Title:A joint Feature Extraction and Data Compression Method For Low Bit Rate Transmission In Distributed Acoustic Sensor Environments
Abstract:Unattended passive acoustic sensors are among the widely used sensors for remote battlefield surveillance, situation awareness and monitoring applications. These small and cost effective sensors can provide real-time information about different types of ground and airborne targets. They are rugged and reliable and can be left in the field for a long period of time after deployment. To improve the spatial resolution for separating multiple closely spaced targets that move in tight formations while reducing the on-board computational requirements, a modest quantity of single microphones could be deployed in a surveillance area of interest. These microphones are considerably less expensive, small sized and contain generic DSP boards capable of performing simple detection, feature extraction and data compression tasks. They are also equipped with basic communication systems to transmit essential compressed target information to a master station which has more sophisticated computational power to carry out high-level operations for sensor array processing and target detection, tracking, and classification. This Phase I research involves development of a joint feature extraction-data compression/encoding method for low bit rate transmission of essential target information to a master computer. The extracted subband features would allow for detection and preliminary classification of the targets in time-frequency as well as data compression and encoding. In this framework, only essential frequency and tonal target features that are needed for accurate target localization and classification will be encoded and transmitted, thus yielding a low bit rate without incurring degradation in the overall detection, tracking and classification performance. This study will also propose new methods to adaptively form sensory arrays based upon coherence information. The effectiveness of the developed schemes will be demonstrated on real and synthesized data sets.

Title:Generic Miniature Acoustic Processor for Distributed Beamforming
Abstract:The U.S. Army is seeking an innovative low-cost generic sensor information transmitter with the capability to compress input acoustic signals at a ratio of 100:1 to transmit essential acoustic signatures to a remote master computer, and to execute high-performance beamforming. In response to this Army need, Physical Optics Corporation (POC) proposes to design and develop an innovative, programmable, generic miniature acoustic processor, called the Adaptive Information Remote Tactical Acoustic Processor (AIRTAP). The AIRTAP is a miniature electronics package with an innovative architecture based on unique integration of commercial off-the-shelf hardware, including generic miniature digital signal processing, SRAM and an FPGA controller, performing two-step compression: acoustic wavelet maxima analysis, reducing data by 25:1, and compression optimal vector entropy processing for an additional 4:1. In this way AIRTAP can achieve the 100:1 compression ratio Army is seeking without any loss of essential acoustic signatures. The generic AIRTAP can be customized to particular applications of the Army's choosing. The AIRTAP will cost around $105 per unit in mass production. In Phase I, a preliminary AIRTAP prototype will be developed to demonstrate its capabilities: acoustic signal processing and compression for high-performance beamforming with minimum microphone arrays.

Title:Harvesting of Recoil Energy from Shock Loading
Abstract:KaZaK Composites, Inc. (Woburn, MA) proposes to design and implement a system for energy harvesting of the G-force recoil energy imparted to projectiles during launch. The innovative device will use piezoelectric actuators coupled with a load transfer mechanism to convert the launch shock load into electrical energy which will replace existing battery power sources onboard projectiles. The device will be compact enough to fit into the space available inside each projectile, with no modification required to its external geometry. It will have the potential to generate the power required to operate sensors, seekers, directional devices, and other control systems embedded in the projectile. Being robust and self-contained, the device will be easy to incorporate into new munitions and retrofit into existing ones. The added capabilities afforded by the proposed system will improve range and targeting accuracy and offer potential weight and cost savings. Perhaps the most attractive feature of the system is the fact it eliminates the need to rely on batteries for powered projectiles, thereby allowing potentially unlimited shelf life. Multiple applications are anticipated for this type of system in any industry where shock loading is present and can be used as a free energy source.

Title:Piezoelectric Actuation system for Small Arms Gun Barrel Stabilization
Abstract:The innovation of this proposal is a configuration to achieve an active barrel stabilization system which: . uses piezoelectric components as the core of the actuation mechanism, which provide high bandwidth, backlash free motion, . uses electronic compensation to cancel piezoelectric element hysteresis and creep, . minimizes the size and weight of the piezoelectric actuators by using single crystal relaxor based piezoelectric components and by incorporating mechanical amplification, . is configured to allow the piezoelectric crystal to be mounted close to the shooter (minimizing aligned with the barrel of the gun, . decouples the shock of the weapon firing from damaging the crystal by using mechanical amplification, and by creating motion at 90 degrees from the motion of the piezoelectric component, . uses accelerometers to sense barrel motion and closed loop motion compensation to eliminate the motion in the compensation system pass-band. This approach eliminates the need for signal integration (eliminating drift problems), and small errors are inconsequential. Intelligent Automation Inc. has built systems which use this exact method of motion compensation and has eliminated random external vibration by 20 dbs and predictable motion by 40 dbs. In these systems sensor and actuator drift were irrelevant.

Title:Small Arms Gun Barrel Stabilization Using High Energy Density, Rugged, and Low Creep Actuators
Abstract:Reducing or eliminating shooter induced disturbances, especially in combat situations, can have a substantial impact on the accuracy of fire, especially in combat situations. Under this effort, an INertially STAbilized Rifle (INSTAR) system prototype employing active stabilization will be developed and tested. A major focus of this effort is the development of novel low creep, highly rugged, precision actuators. Of relevance to this work will be issues relating to actuator displacement, force, bandwidth, packaging, mass, powering, and control. The research team will use its considerable expertise, which is based on previous INSTAR development and other smart structures work, to address these issues.

Title:Low Cost, Composite Modular Packaging with Biodegradability for Military Supplies
Abstract:KaZaK Composites Incorporated (KCI), with assistance from the University of Massachusetts at Lowell, proposes to develop and produce an innovative modular packaging system for use in the transport and delivery of military supplies. The motivation for such future packaging systems is driven by the current need to enhance operational efficiency of soldiers in the battlefield through swift and accurate provision of supplies. In addition to the low cost, modular, and lightweight construction inherent to providing such efficacy, modular packaging will incorporate features of biodegradability, fire resistance, and favorable munitions stabilization under mechanical impact and excessive thermal loading. KCI development efforts will focus on the production of novel, low cost, and lightweight packaging systems for delivering both solid and liquid contents through the application of advanced fiber reinforced composite materials, along with the appropriate use of metal / composite hybridization. Composite materials offer enormous flexibility in constituency, allowing precise tailoring to mechanical, electrical, and chemical performance requirements. Processes such as pultrusion, filament winding, and injection molding will be employed to produce large quantities of packaging at competitively low costs. KCI has considerable experience in novel munitions packaging and has demonstrated a 60% weight reduction over comparable metal designs.

Title:Energy Transmission, Using Self-Channeling Short-Pulse Lasers.
Abstract:Ionized laser filaments can be generated with very small amounts of energy, as long as the energy density in the laser pulse is sufficiently high. The effect has been demonstrated over meters, without suffering the defocusing effects of diffraction, and it has shown remarkable immunity to turbulence, density gradients, and combustion and combustion products. Filaments carry lethal energy densities, capable of destroying any material in their path, and they have been demonstrated to scale over an order of magnitude. Current models predict the effect to scale over at least three further orders of magnitude, generating ionized paths of kilometers in length. An ionized path can serve not only as an electrical conduit, but also as an optical waveguide. As a result, this project will investigate the use of these long ionized paths (filaments) to channel large amounts of electrical and/or laser energy on target.

The device will use the direct piezoelectric effect as actuated by fluctuations in the environment of the storage area. A NiTiNol actuator will be used to suplement the piezo actuator. The Phase I work will result in an early design and will demonstrate proof of principle. Phase II will result in an advanced prototype design that will be thoroughly tested in environmentally controlled laboratory conditions. The applicability to other military needs will also be investigated.

Title:Micro-Optomechanical Orientation Sensor
Abstract:The U.S. Army is seeking innovative autonomous onboard orientation sensors for munitions and other orientation measurement applications as alternatives to rate gyros and GPS. Conventional rotating wheel accelerometers lack long-term reliability, and are limited in accuracy and resolution. Precision fiber optic and ring laser gyroscopes are too expensive and too large for use in most munitions. MEMS accelerometers fabricated by surface micromachining are too thin to be sufficiently accurate. To address this need, Physical Optics Corporation (POC) proposes to develop a new cost-effective Micro-OptoMechanical Orientation Sensor (MOMOS) based on a grating and an integrated optical chip, capable of measuring angles less than 0.05 mrad. MOMOS is a novel design and integration of commercially available microelements, diode lasers, microlenses, and photodetectors in a waveguide or free-space configuration, with a Bragg grating element mounted on a bulk micromachined torsion base. This new design overcomes the limitations of bulk (3D) MEMS, increasing angular sensitivity and accuracy by orders of magnitude. In Phase I, POC will design, fabricate, and test the proposed angular orientation sensor technology, and demonstrate its feasibility by analytical calculation, computer modeling, and experiment. In Phase II an advanced MOMOS prototype will be fabricated and field tested.

Title:Mass Fabrication of MEMS-based Micro Detonator Technology
Abstract:Potential applications of micro-explosives range from munitions, anti-tamper devices and automotive airbags, to spacecraft components and fire suppression. By applying IC manufacturing methods to explosives devices, MEMS technology enables miniaturization, cost savings, and more intelligent systems. A less obvious feature of this technology is its reliability: ultra-pure materials and statistical process controls make IC techniques ideal for producing devices with consistent behavior. A key barrier to applying this new technology has been packaging. With few exceptions, MEMS require hermetic packaging. This is true of chemical systems such as explosives, as well as most other types of MEMS. In the special case of an explosive device, the processing temperature is also a consideration. Hermetic packages usually require temperatures in excess of 300§C during the sealing step, which exceeds the safe handling temperature of many explosives. To meet the packaging requirements of MEMS - i.e. reduced cost, temperature, and size - work was begun by the MicroAssembly team ten years ago, to develop a new type of hermetic package. In this approach, IC manufacturing techniques were employed in the package itself. Reduction of the seal contact area allowed application of extremely high pressures. This allowed a uniform seal to be accomplished at room temperature.

Title:Mass Fabrication of MEMS-based Micro Detonator Technology
Abstract:Tanner Research proposes to leverage an ongoing four-year development effort, supporting ARDEC Warhead and Energetic Directorate in part, to implement low-cost micro- energetics devices for use as `nano-scale' initiators and detonators. Tanner's micro-energetics devices are currently 2.5mm and mass fabricated in silicon and glass with the energetics applied during a post-processing procedure. The complete detonator device requires about 50 æjoules at 3vDC for initiation. Tanner will develop two MEMS-based mass fabrication techniques to demonstrate processes for single-point and multi-point precision-application detonators. For example, high volume, high throughput manufacturing and loading is facilitated by fabricating the initiator/energetics on a cost effective substrate. Tanner contends that detonators can be mass-produced at approximately 20-cents per device with this fully integrated process. During Phase I, Tanner will also study the efficacy of applying a pioneering technique for mass loading of energetics into micro and nano-scale cavities, called READ. This technique, although more costly, will ensure multipoint initiators (MPI) have absolute simultaneity through an identical, controlled fabrication process.

Title:Advanced Multi-Sensor Array System (AMAS)
Abstract:In this Phase I SBIR, Vista Clara and Quantum Magnetics propose to demonstrate the feasibility of detecting and tracking military vehicles at very long ranges using a long-baseline array of magnetic and acoustic sensors. Our AMAS system concept is based on a novel multi-sensor acquisition device, and advanced magnetic/acoustic data fusion techniques. The Phase I work plan will establish the technical feasibility of this concept by accomplishing the following tasks: 1) assemble and test 4 copies of the prototype data acquisition device; 2) develop and evaluate magnetic noise mitigation algorithms and long-baseline magnetic/acoustic tracking algorithms; 3) demonstrate prototype hardware and tracking algorithm performance through Phase I field experiments at Picatinny Arsenal. The proposed work builds directly upon Vista Clara's recent advances in magnetic array processing and magnetic/acoustic sensor fusion techniques, and QM's unparalleled expertise in the design and fabrication of inexpensive magneto-resistive magnetometers. As a Phase I Option, Vista Clara and QM will design, assemble, test and deliver a universal magnetometer calibration instrument, and investigate the feasibility of magnetic/acoustic data fusion for ground vehicle classification.

Title:Ruggedized Solar Charging System for Remote Operation
Abstract:Unattended ground munitions, sensors, and communications systems delivered by air, missile, or rocket face formidable challenges. High deceleration impact during delivery places severe demands on the mechanical strength, while long term continuous operation in a wide variety of environments requires rugged components and a renewable energy source. Additionally, the unit must remain covert requiring low profile and low reflective surfaces. SensorMetrix proposes an impact hardened, environmentally rugged solar power unit for charging onboard secondary batteries. An innovative approach to handling unpredictable lighting situations, such as local solar obstructions, oblique solar incidence and indirect lighting, is proposed to optimize solar power collection. The unit is designed to be operational in a full range of environmental conditions. A smart power management system makes the unit expandable and adaptable to other applications, including multiple battery chemistries, while being compliant to standardized sensor/transducer network protocols. A focused impact testing program using large state-of-the-art gas guns will be undertaken to understand and control damage, and to insure impact resistant designs.

Title:Remote Sensing of the Electro-Magnetic Potential of the Human Heart
Abstract:In 2002, QUASAR demonstrated clear detection of the electric potential produced by the heart at a distance from the subject of order 1 m. Measured data and preliminary calculations show that detection at 5 m should be possible with existing sensor hardware, and that stand-offs greater than 10 m might be achievable with improved sensors presently in development. In Phase I we will develop an accurate electric (E-) field model of the heart/body system in order to project the potential produced by the heart out to arbitrary distances. We will also determine the effective system measurement noise floor to be expected when filtering and signal averaging are included. A breadboard prototype heart potential sensor system, comprised of a pair of existing QUASAR electric potential sensors about the size of a dime (10› coin), and a laptop computer for data acquisition and storage will be demonstrated in a shielded room, and in a normal outdoor urban environment. In Phase II a complete man-portable or gun mountable system that detects and locates personnel via the electric potential produced by the heart will be developed and demonstrated.

Title:Tungsten Carbide Nanoparticle Strengthened Tantalum Nanocoating for Engineered Gun Barrel Surfaces
Abstract:US Army seeks innovative coating technologies for gun barrel surface applications to replace currently available highly toxic electroplated hard chrome. Cylindrical magnetron sputtered tantalum (Ta) coatings developed by US Army labs revealed some success in explosive bonding experiments, however, issues include cost and softness of the unalloyed Ta. Inframat proposes to fabricate a novel tungsten carbide (WC) nanoparticle strengthened Ta nanocoating via an environmentally benign co-electrodeposition process, where WC nanoparticles are co-deposited in a Ta matrix. The proposed program involves (1) preparing a colloidal bath composition containing WC nanoparticles in Ta solution, (2) depositing Ta-WC nanocoatings via IMC's proprietary co-electroplating process, and (3) evaluating coating properties. From our previous experience in electroplated WC/Co-Ni nanocoatings, we expect that the Ta-WC nanocoating will have significantly increased coating to substrate adhesion strength when compared with electroplated microsized hard chrome. The program is aimed to engineer the alloy hardness to a range compatible to hard chrome (850-1000 VHN). Since Ta and WC are high temperature materials, having melting points >3000oC, thermal mechanical fatigue and erosion wear properties are expected to outperform hard chrome coatings. The substitution of Ta with commercially available WC nanoparticles is expected to reduce cost of the alloyed Ta by 40%.

Abstract:The overall objective for this project is to develop and advanced electronic pointing device (EPD) for indirect fire weapons, specifically the M224, M252, M120 and M121 series mortars and M119, M198 towed howitzers. During Phase I, Luna Innovations will evaluate novel approaches to fiber optic gyroscopes for use as an EPD. During Phase II, prototypes will be constructed and field tested. During Phase III, the system developed will be integrated into existing mortar and artillery systems. Experimental data and modeling of fiber optic gyroscope designs based on systems developed and produced by Luna Innovations show the potential for extremely high-accuracy and low drift measurements. Additionally, wireless technology will be implemented to enable improved battlefield awareness. While the focus of this project is indirect fire weapon pointing, a larger market exists in inertial navigation systems for weapons, aircraft, and the automotive industry. Luna Innovations will collaborate closely with the U.S. Army and other DOD branches to ensure that the EPD developed here will integrate seamlessly with existing and emerging systems. With over 13 years of experience in a wide range of fiber optic instrumentation systems, Luna Innovations is uniquely positioned to apply advanced fiber optic technology to address this opportunity.

Title:Advanced Neutron Source for Radiography & Tomography
Abstract:Alameda Applied Sciences Corporation proposes to design in Phase I a pulsed neutron source based on dense plasma focus (DPF) technology that is practical for thermal neutron radiography. A fully operational source will be fabricated in Phase II. The neutron production/pulse by available sources and the resultant thermal flux on target are estimated to be about five orders of magnitude below what is required for radiography at practical source-to-sample distances. This proposal is to demonstrate that we can reduce the gap between requirement and present capability by several orders of magnitude, by exploiting the strong (I10) scaling of neutron output with pulsed DPF current in the range 300-500 kA. Since the neutron yield of DT is about 100 times that of DD, a practical source for thermal neutron radiography would be within reach, if not through the DD reaction, then through the DT reaction. We envisage a 1.5 m3 DPF source that can be carried around on a flat-bed truck and operates with two different moderators: a thermal neutron source to fit the Army's radiography needs and a ~250 keV homeland security source, for high sensitivity detection of fissile materials in improvised targets that use larger quantities of masking materials.

Title:Real-Time Robotic Control System for Titanium Gas Metal Arc Welding
Abstract:The Army is working to satisfy the demands of a future force that will be organized, manned, equipped, and trained to be strategically responsive, deployable, agile, versatile, lethal, survivable, and sustainable. Titanium addresses the Army's need for high strength-to-weight characteristics and can meet the performance and transportability requirements of lightweight systems. Welding and joining technologies enable improved manufactured components by reducing the weight, production time, and cost of jointing parts. Improved welding technology increases product lifetimes and makes possible the fabrication of large structures. Gas Metal Arc Welding (GMAW) has the potential to improve the quality, speed, and penetration depth of titanium welds significantly, without increasing the cost per part. However, this result can only be achieved if proper shielding is provided and proper weld parameters selected. The goal of this project is to develop a Real-Time Robotic Control System for Titanium GMAW for current and future Army and commercial applications. Our real-time weld control system will integrate: (1) feedback sensors that measure weld characteristics; (2) a method of adjusting the welding parameters; and (3) real-time adaptive control algorithms to make critical changes to the weld parameters during welding to achieve high-quality welds.

Title:Real - Time Robotic Titanium Welding (1000-311)
Abstract:Triton Systems, Inc. proposes to develop a robotic gas metal arc welding (GMAW) capability using a real-time integrated titanium welding monitoring and control (Ti-WMAC) system, which will use images in both visible and infrared spectra to sense the arc length and weld pool (respectively) generated in the welding process. GMAW is commonly employed for structural steel and aluminum applications, but the state of the art for this technology in titanium is in its infancy, certainly where real-time quality monitoring and control in a robotic welding system is concerned. Real-time data on weld pool and arc column length parameters coupled with nominal welding parameters, such as current and torch speed, will allow the robotic system to monitor the welding process and make critical modifications to continually maximize weld quality. Triton's innovative Ti-WMAC system, will enable the Army to replace their current steel parts with lighter fabricated titanium parts. Lighter-weight structural components are critical to the Future Combat System (FCS) initiative applications, such as lightweight howitzers and machine guns.

Title:Ovates: Predictive Agents for Homeland Defense
Abstract:ALPHATECH proposes to design and develop an approach to the identification and prediction of events from the semi-automated fusion and evaluation of information from multiple disparate data sources. The core of this proposal is the semi-automatic, ad hoc, and intelligent assembly of fragments of Bayesian networks to form adaptive belief networks that contain hypotheses about current and future events. The occurrence of events recorded by the data sources initiate the assembly of the belief networks, and additional data resident in the data sources are used by Ovates to evaluate the hypotheses and prune those with low likelihood of occurrence until only the most likely hypotheses about future events remain. The Ovates Bayesian blackboard, which supports the inferential predictive reasoning, is based on the classic blackboard architecture, extended for Bayesian inferential computations, agent-oriented knowledge sources, and a multi-agent architecture that provides access to the data sources. Problem and data source descriptions are based on semantics encoded in ontologies based on the DARPA Agent Markup Language (DAML) and the Ontology Web Language (OWL). Ovates is intended to predict the potential occurrence of terrorist threats within a community based upon local data sources such as emergency room, police, and first responder reports, traffic and police surveillance, and harbor activity reports.

Title:Intelligent Agent Technologies for Homeland Defense
Abstract:This effort proposes a solution for Intelligent Homeland Defense Software Agents (IHDSA) that will autonomously retrieve, filter, fuse, and make predictions using relevant Homeland Defense data. The suite of intelligent software processes will gather data from distributed heterogeneous networks, extract relationships between the data, display and forward the relevant product, and then execute predictive analysis to extrapolate the relationships among data and environments to formulate situation and threat assessments. Intelligent software retrieval processes (`agents`) will retrieve relevant data from heterogeneous sources and translate it into a common email-like format. The retrieval `agent` will subscribe or poll the external network of systems for relevant information, filter the results, and then apply further processing and routing to them. The software `agents` will incorporate necessary processes to access, retrieve, and deliver data from each network. The accumulated data may then be processed in a machine-to-machine (M2M) interface without having to await manual screening and association. Returned data will be displayed in an intuitive interface depicting the current operational environment and its associations with the incoming data. A software model for predictive analysis will explore the relationships between events, topics, individuals, locations and time to express a situation or threat assessment.

Title:Agent-based Terrorist Attack Prediction (ATAP)
Abstract:We propose to develop a prototype for Agent-based Terrorist Attack Prediction (ATAP) for Homeland Defense. ATAP will employ mobile agents to retrieve on demand relevant data distributed across various services, multi-national forces, and intelligence agencies, while maintaining the autonomy of individual data sources. ATAP will use ontology-based data modeling for integrating heterogeneous, distributed data sources. ATAP will incorporate Bayesian Belief Network (BN) technology for building models representing interrelationships among various domain concepts such as terrorist activities and observable events, thus allowing models to predict potential attacks based on those observable events. Finally, ATAP will incorporate a simulation environment supporting speculative analysis and exploration of model-generated hypotheses, via realistic simulated terrorist attack events that are based on input such as the attack location, environmental factors, social networks, etc. The Phase I effort will focus primarily on bioterrorism, and ATAP will help predict both bio-attacks and early detection of disease outbreaks due to such attacks. We intend to rapidly develop a prototype based on: 1) our in-house agent-based information retrieval engine ACQUIRE; 2) a domain ontology encoded with Prot‚g‚ 2000 from Stanford; 3) our in-house BN engine BNET 2000; and 4) Carnegie Mellon's simulation environment BioWar.

Title:Threat Assessment and Prediction System (TAPS)
Abstract:The intelligence community as a whole has suffered from information overload due to a glut of information and a dearth of analysis. With the restructuring of the intelligence community, and the redirection of information flow to widen dissemination, the amount of information that must be analyzed is increasing rapidly. Analysts in support of Homeland Security must mine not just the usual information sources such as the FBI, CIA, NSA, and State Department, but the ever increasing number of new and important sources like the Immigration and Naturalization Service, all levels of law enforcement agencies, and various transportation and communications sources. Even with better training in detecting patterns and indicators across the expanding universe of information and a greater depth of information management experience, analyst will still require new and innovative, user friendly, data mining, and pattern recognition analytic tools to effectively and efficiently sort through and analyze this enormous volume of data. CHI Systems has developed a software infrastructure from current project efforts for a system that uses intelligent agents to assist in processing intelligence data and predicting threats for Homeland Defense. This infrastructure will serve as the basis of the proposed Threat Assessment and Prediction System (TAPS).

Title:A Collaborative Peer-to-Peer Approach to Multi-Source Threat Assessment and Prediction
Abstract:The proposed innovation, entitled CiTAPS (Collaborative Intelligent Threat Assessment & Prediction System) combines collaborative software agents, intelligent machine and peer-to-peer technologies to support extensible, interoperable, and fully automated real time indications and warning extraction and dissemination. It provides users with on-demand multi-source data retrieval and fusion, overt threat notification for terrorist activities, and covert threat detection and notification through remote data source monitoring and analysis. Using multiple intelligent software agents deployed to a variety of data sources within a specific domain, CiTAPS is capable of retrieving, fusing, analyzing, and extracting anomalies from multiple sources of heterogeneous data for integration into a Common Relevant Operational Picture (CROP). These agents are able to collaborate within their own domain using standards-based communications for agent frameworks. Our team's approach is to build upon previous research findings on peer-to-peer technologies, leverage those against the Homeland Defense's Intelligent Agent problem, and create a formal standards-based architectural design and an interactive visualization tool outlining the major concepts of the proposed system.

Title:Intelligent Agent Technologies for Homeland Defense
Abstract:In future military operations, intelligence analysts will have access to unprecedented quantities of surveillance data. Toyon proposes to develop an architecture that employs "intelligent software agents" to reduce information overload for the operator by automating many of the intelligence processes. This architecture will also be robust with respect to changing network conditions. The architecture consists of three categories of intelligent software agents: User-Interface Agents, Task Agents, and Information Agents. The User-Interface Agents translate user commands into requests for the Task and Information Agents. The Task Agents automate many intelligence-analyst tasks by using data synthesis algorithms. The Information Agents respond to requests for data by searching the data sources at their network location, and fusing the accumulated information. The intelligent agent architecture will be developed using a simulated intelligence, surveillance, and reconnaissance sensor network. Toyon will demonstrate the system architecture using various formats of data sources produced by simulations which enable tracking with ground-moving-target-indicator (GMTI) radar, track-level fusion between multiple track databases, and multi-sensor data fusion. At the conclusion of Phase I, Toyon will demonstrate the system architecture using a simplified user interface and a small set of rules to govern the behavior of the Task Agents.

Title:Integrated High Resolution Thermal Imager with Small Optics
Abstract:Intelligent networks of distributed, unattended sensors of many modalities serve for increased situational awareness in all echelons of the Army. Applied Science Innovations (ASI) proposes Automated Panoramic Thermal Imaging Sensor (APTIS) with 360ø field of view optics to provide instantaneous full horizon detection, location and tracking of multiple targets. These functions of the integrated sensor will be enabled and enhanced by the new high-resolution panoramic imager. In existing panoramic cameras, the inherent aberrations of the reflector result in smaller effective apertures and larger optics. New optical designs with aberration correction are proposed as part of the Phase I development. The proposed approach will combine the new, low-cost panoramic optics with the implementation of algorithms for target detection, location, and tracking, as well as power management and wakeup capability. GPS navigation and interface for communication with a distributed network of intelligent sensors will be provided. Phase I project will prove the feasibility of the concept, while Phase II will produce a viable, first generation prototype system. In Phase III, commercial applications of APTIS will serve the needs of the Army and other branches of the Armed Services, as well as civilian applications such as security and law enforcement.

Title:Artifact Reduced Tomographic Algorithms
Abstract:JDLL will experimentally rank the four most troublesome causes of artifacts in 2D and 3D industrial computed tomography (CT), including imprecise geometry, beam-hardening, scatter, and partial volume effect. We will then demonstrate artifact reduction algorithms corresponding to the most critical. We propose six promising candidate algorithms. Four of these are original. We also propose two promising algorithms developed for medical CT but not yet applied to industrial CT. In Phase I we will evaluate and deliver demonstrations of the most promising algorithms. In Phase II we will complete all demonstrations and deliver a prototype reduced-artifact CT reconstructor. This reconstructor, which incorporates each successful algorithm, will be productized for two markets: new turnkey CT systems and retrofitting of existing JDLL systems. With over 100 man-years of CT experience, members of the JDLL team have designed and built production industrial CT systems and implemented hardware and software solutions for yielding exactly the data required at the expense of low-priority data. Our most successful programs have always been by involving likely end-users done from the get-go: United Technologies and Alliant Techsystems, who already possess JDLL's production UCT and HECT2 systems, have already expressed enthusiasm for this proposal's Phase III.

Title:Innovative 3D Microbolometer Arrays for Hyperspectral Infrared Imaging
Abstract:Although uncooled infrared (IR) imaging technology has made remarkable progress in the last two decades, a major limitation of 2-D IR focal plane arrays is the lack of real-time spectral discrimination. Multi-spectral detection capabilities are highly desirable for advanced IR imaging systems and can be especially beneficial for early threat warning applications in missile defense since they enable rapid, efficient and multi-dimensional scene interpretation. Systems that gather data in multiple IR spectral bands in real time can discriminate both absolute temperature and unique spectral signatures of objects in the scene. Furthermore, they can effectively reject spurious information, such as background clutter and sun glint from an IR image, leaving only the objects of interest for rapid threat identification. Foster-Miller proposes to design and develop an innovative 3-D micromachined array of bolometric detectors using standard semiconductor micro-fabrication technology capable of hyperspectral imaging in the mid-IR region. The 3-D microbolometer structure will measure simultaneously the entire hyperspectral data cube, i.e., the intensity of the infrared energy in narrow spectral bands for each picture element in the scene. The proposed effort targets its application to missile seeker IR optics where benefits in space, weight and complexity will have a significant impact. (P-030678)

Title:Automatic Optimization of Warhead Performance Measures
Abstract:We propose to develop an improved system for optimizing the design of explosive warheads. Current warhead optimization technique will be advanced on several fronts. The optimization strategy will be modified to take advantage of an abundance of computer power: in each optimization step, "extra" simultaneous warhead-performance computations will be performed to: 1) explore a larger domain of the design space; 2) reduce the effects of numerical noise; and 3) compute higher-order derivatives of the objective function. This will allow more rapid achievement of design goals. For each type of warhead, we will establish a set of intermediate warhead-performance quality measures that are specific to that warhead's ultimate performance goals; special post-processing software will be developed to evaluate these objective functions from hydrocode output. This will ensure that an optimization successfully results in optimal performance of the warhead against its intended targets.

Title:HyperSpectral Data Cube Processor
Abstract:We propose to implement a Hyperspectral Cube Processor by prototyping it on a set of innovative proprietary FPGA (Field Programmable Gate Array) boards which will lead to a highly compact, maximally parallel design. The proven design will be transferred to ASICs (Application Specific Integrated Circuits) in the Phase II program. Along with compactness and parallelization, we will be working toward maximal scalability e.g. the ability to expand for higher data traffic and for more complex operations by just adding more of similar modules, without major reorganization. In the FPGA prototype, we will use a mesh architecture (i.e. with all chips or boards inter-connected in a complete graph) with a serial, 10 Giga-bit/sec mesh backplane. The processor will employ our proprietary technology of massively parallel algorithms in hardware programming. The ultimate goal of the design is to distribute the Hyperspectral Image Processing between the inter-connected ASICs of the Processor in the most efficient way, thus providing the most compact device given the data traffic volume.

Title:Hyperspectral Image Processing Platform (HIPP)
Abstract:Coherent Logix, Incorporated proposes to develop a Hyperspectral Image Processing Platform (HIPP) that will be able process 30 hyperspectral cubes per second, where a hypercube is approximately 100 MegaByte (MB) in size. The platform will be reprogrammable and dynamically reconfigurable to support static and dynamic application requirements and support lifetime field upgrades. Additionally, the HIPP will based on a "hardware under software control" architecture that provides an open [hardware and software] architecture supporting integration for embedded system applications. This computation intensive HIPP system will be enabled by Coherent Logix's HyperX processor technology currently supported by U.S. Army TACOM-ARDEC and the Defense Advanced Research Projects Agency. The HyperX technology is a revolutionary breakthrough in signal processor design that provides more than ten times the processing capability at less than one thirtieth the power of current state-of-the-art digital signal processors that result in critical weight, size, and power reductions. In the Phase I program, Coherent Logix will work with the Government to further define the HIPP requirements and identify optimizations off the base HyperX design that will facilitate more efficient hyperspectral image processing. In Phase II, Coherent Logix will develop a prototype HIPP system.

Title:Measurement of Career Leadership Performance
Abstract:In June of 2000, as part of the Army's Transformation Campaign Plan, the Chief of Staff, Army, (CSA) chartered a panel of both military and civilian experts to look at training and leader development within the Army. This panel of experts surveyed over ten thousand soldiers in the field; it concluded that current Army training and development programs do not successfully develop the self-aware and adaptive leaders necessary to execute the full spectrum operations of the Objective Force. We propose to design a web-based tool that will lay out a "map" of the career path that will produce the leaders needed for tomorrow's Army. The Leadership Measurement and Assessment Program (Leadership-MAP) will link measurable, validated leadership competencies to the career experiences (training, assignments, activities, accomplishments) that are associated with the acquisition of those competencies. At the end of Phase I, we will develop a proof-of-concept for the Leadership-MAP tool, with specifications for how the final tool will be developed in Phase II. The Leadership-MAP will provide guidance to individuals who are developing their leadership skills, to Army personnel managers and commanders providing guidance to developing leaders, and to the institutions responsible for creating opportunities for leadership training.

Title:Question Asking and Answering for ADL
Abstract:There is a pressing need for networked intelligent Question Asking and Answering (QAA) systems capable of interacting with soldiers and DoD civilians anywhere/anytime. These users may have training needs, on-the-job questions, or be deployed in the field. While SMEs could answer many questions, they are often unavailable, and if available, not able to respond instantly. Fortunately, QAA systems are maturing. Recent advances in automatic text understanding (Latent Semantic Analysis) coupled with deeper computational linguistic analyses, such as understanding how language is used to form requests or questions (speech acts) and relating speech acts to responses users are seeking, may allow us to semi automatically construct mature QAA systems whose performance is indistinguishable from knowledgeable human intermediaries. In Phase I we propose constructing a SCORM conformant QAA system that uses LSA as a cornerstone, augmented with paragraph retrieval, relevance feedback, and automated summaries. We add to this syntactic parsing and speech act classification to answer queries about material in distributed learning courseware and other DoD information repositories. While LSA tools give broad brush answers, for finding text containing the answer, the other computational linguistic tools will be used to construct more refined answers for the user.

Title:Question Accumulation and Response Tool for Education and Training
Abstract:Students in distance learning classes have at least as much need to ask questions of their instructors as students in more conventional settings. However, distance instructors are not always available when students need help. Across a course and its repeat offerings, many questions recur frequently. This provides possible leverage for incrementally constructing custom question-answering systems for particular distance learning courses, as a way of making better use of available instructor time. Stottler Henke proposes to apply its extensive experience with intelligent instructional systems, language and knowledge processing, plus its evolving in-house tool-base to build an innovative tool to lower the cost of creating, administering, and maintaining a high precision question-answering system for instructional applications. In this Phase I project, we will (1) explore major technical challenges in areas such as semi-automated learning of questions and answers, and incremental refinement of questions and answers through dialog, (2) design an overall system that uses a diverse set of language processing and machine learning techniques to support storage, retrieval, and construction of accurate question answers, and (3) build a limited proof-of-concept prototype that illustrates the utility of our proposed approach to constructing a QUestion Accumlation and Response Tool for Education and Training (QuARTET).

Title:Enhancing Warrior Ethos in Initial Entry Soldiers
Abstract:Warrior Ethos is an important concept particularly for the Armed Forces. Senior leaders within the Armed Forces are seeking ways to inculcate the Warrior Ethos into each soldier, sailor, marine and airman. The Warrior Ethos SBIR project is targeted to initial entry soldiers but does have applicability across all Armed Forces. As the Objective Force exploits advances in information technology, the battlefield will grow more dispersed and the attributes of Warrior Ethos will become even more important for leaders and soldiers. General Richard B. Myers, Chairman of the Joint Chiefs of Staff, defines the baseline attributes of Warrior Ethos as cohesion, commitment, self sacrifice, courage and leadership (Myers, 2002). As research provides a better understanding of these attributes, it will become possible to examine the feasibility of developing programs to train and sustain Warrior Ethos by providing an environment in which to foster its development.] Our Phase I objectives are as described: Objective 1: Review and analysis of warrior ethos. Perform a literature review and discussions with soldiers. Perform analysis of several types of soldiers including combat arms, combat support and combat service support across several type units. Objective 2: Identify training techniques, systems, vignettes and metrics. Explore available training techniques and systems including simulations and distance training to determine if and how warrior ethos attributes can be imparted on soldiers through self-study and pre-commission. Develop training vignettes that are exemplars of the attributes of warrior ethos to use in various training programs tailored to the target audiences of soldiers in initial entry training, soldiers in units, non-commissioned officers and officers. Propose metrics by which progress can be measured. Objective 3: Feasible plan for development of product in Phase II. A plan will be produced for development of a warrior ethos training package which is technically feasible and commercially viable. Objective 4 (option): Concept Demonstration. The concept demonstration will show the art of the possible in a way that is as tangible and operationally relevant as possible. It will increase the quality of our collaboration and increase confidence about our Phase II plan.

Title:Ascertaining Bio-Mechanical Response of Armor Materials
Abstract:This proposal describes a project to develop an integrated system to measure the energy and impulse transferred through a piece of body armor material subjected to ballistic and non-ballistic loads. The proposed system is independent of the target and body armor material and can be applied to any combination of materials deemed relevant in the future. As part of this effort, a signal conditioning and data acquisition system will be developed that will report pressure, impulse, displacement, and energy transferred to the target as a function of both time and location. In Phase I, a system will be designed, physically modeled, and tested to demonstrate the operation of the system under dynamic loading. The initial use for this system will be to test body armor systems and, using a biomechanical model currently under development, predict the injuries likely to be sustained by the wearer under a variety of attack scenarios. The final system will be commercialized for application to protective garment testing of all kinds including bulletproof vests and sports equipment, testing the response of the human body to impacts for safety and forensic projects, and characterizing the response of malleable materials to static or dynamic loads.

Title:Actively Controlled Rotary Actuator For Vehicle Suspensions
Abstract:For a new paradigm in mobility, future military ground vehicles may look to animals for the added benefits of walking or crawling motion to supplement advanced wheel drive systems. Such hybrid mobility approaches show promise towards overcoming tradeoffs associated with a dedicated wheel or track-based system. A critical requirement for wheel placement in a walking or crawling motion the elimination of packaging and performance constraints imposed by the use of strut-type suspension. RMSV's rotary actuator package represents an innovative approach to replacing a passive, semi-active, or fully active linear suspension used in a leading or trailing arm configuration. The result is an actuator system that combines the functions of a spring and an active damper, allowing efficient, wide bandwidth operation over both traditional and previously impassable terrain. Our concept supports high force, high speed suspension articulation in an extremely compact package that supports the benefits of new technologies such as in-hub motors. RMSV's concept leverages the existing hybrid-electric power system of future tactical vehicles to achieve compact size, light weight and high efficiency unattainable with a hydraulic or pneumatic-based solution.

Title:Compact and Efficient Logistic Fuel (CELF) Reformer
Abstract:To effectively use fuel cells in military and commercial applications, diesel fuel and JP-8 need to be reformed in a compact, reliable and highly efficient reformer. Altex Technologies Corporation (Altex) and Pennsylvania State University (PSU) have identified the Compact and Efficient Logistic Fuel (CELF) Reformer that overcomes the fuel sulfur and carbon formation tendencies of logistic fuels and transforms them into a reformate suitable for SOFCs. This is achieved with a reformer that is projected to have 80-90% efficiency. The base technology for this reformer is being developed under DARPA support for a 20 watts SOFC operating on JP-8. Under the proposed Phase I program, the technology will be scaled up to a 2 KW system and the components that require testing with diesel fuel will be tested to show the feasibility of CELF to meet the DoD and the commercial market goals. This system design and testing and performance and cost evaluations will be the basis for the Phase II effort to fabricate, demonstrate and deliver a CELF/SOFC prototype system.

Title:Compact Fuel Processor for 2 kW Solid Oxide Fuel Cell
Abstract:The U.S. Army has the need for small and efficient fuel cell power generation systems (0.5-2 kW) that can operate on diesel and logistics fuels. The advantages of employing these fuels for "in-the-field" power generation in military deployment include high energy density and wide availability. However, one problem with these fuels is that they all contain high concentration sulfur, which is extremely poisoning to most reforming catalysts and fuel cell anodes currently available. Presently, efficient, compact, and reliable fuel processors that are capable of converting diesel and logistics fuels to contaminant-free reformate are not commercially available. The objective of the proposed program is to develop an efficient, compact, and robust fuel processor to reform diesel into contaminant-free H2 and CO, as the fuel for SOFC. The proposed fuel processor will consist of a sulfur-tolerant partial oxidation reformer and a post-reforming desulfurizer as its key components. In Phase I, Aspen will prepare and evaluate a series of candidate materials to identify a highly active, coke- and sulfur-tolerant partial oxidation catalyst and a regenerable sorbent for H2S removal. Preliminary diesel reforming tests in an integrated fuel processor will also be carried out to demonstrate the proposed concept and identify critical technical issues that would need to be addressed in Phase II for prototype fuel processor construction and demonstration.

Title:Ultra-compact steam reforming reactor for SOFC
Abstract:The military is aggressively pursuing fuel cells for forward deployed logistic fuel powered generators. Partial oxidation and steam reforming technologies have not been able to provide systems that are both compact and efficient, however. A fundamentally new reactor geometry under development by Mesoscopic Devices promises to allow compact, fast response, and efficient steam reforming of logistic fuels. The new reactor achieves highly effective heat transfer and catalytic conversion in an extremely compact and simple design. In this Phase I program, Mesoscopic Devices will build the reactor and demonstrate steam reforming of logistic fuels. Detailed system-level modeling will show that the new steam reformer used in a solid oxide fuel cell system with integrated water recovery will have a higher energy density that other generators and will not require an external source of water for steam reforming.

Title:Hydrogen Generation and Storage for Fuel Cell Systems
Abstract:The aim is to develop new/improved nano-materials to remove sulfur containing compounds in reformate gas for use with hydrogen/proton exchange membrane (PEM) or solid oxide fuel cell systems. Small and efficient hydrogen/PEM or solid oxide fuel cell systems are in development to meet the power needs for vehicle-borne battery chargers, vehicle silent watch and field headquarters. The power range of interest is approximately 500 to 2000 Watts. The main difficulty that remains to be overcome for such applications is the development of compact fuel reformers that produce hydrogen gas on demand. Reformate purity is often an issue and processed fuels routinely contain refractory sulfur compounds such as thiophenes and alkyl substituted thiophenes. We propose here to use nano-adsorbents/oxidizers for reformate fuel desulfurization in fuel cell application with a novel carbon and ceramic supported materials structure that maximizes active material surface area and minimizes agglomeration that can occur over high temperature sorption and regeneration cycles. The optimum materials composition and nanostructure will be indentified and further process optimization and incorporation into 0.1-2 kW fuel cell systems will pave the way for future work.

Title:Logistic Fuel Micro-Reformer
Abstract:Precision Combustion, Inc. (PCI) proposes to develop a compact catalytic reactor based on the proprietary Microlithr catalytic substrate technology for autothermal reforming (ATR) of JP-8 and diesel fuel at the 0.5 - 2 kWe scale. The size of the catalytic reactor is expected to be about 6 in3 (2 D-cell batteries) and weigh < 100 grams. The reformate mixture exiting the reactor will have temperature of about 700 C such that it can be directly feed into a downstream SOFC resulting in a compact and efficient power system. The operating conditions for the ATR reactor operation will be optimized to provide complete conversion of the fuel with thermal efficiency above 70%. The amount of steam required by the ATR will be minimized to operate on water recycled from the downstream SOFC. In this program the ATR reactor performance will be demonstrated and the requirements for the integrated system will be analyzed.

Title:Innovative Methods for Geolocation and Communication with Ultra-Wideband Mobile Radio Networks
Abstract:Geolocation capability is a critical component of wireless systems for public safety, military, and homeland security. Traditional geolocation systems based on GPS and narrowband modulations work well in areas where a direct line of sight (DLOS) path from multiple sources exist. However, these systems become unreliabile for indoor and urban environments that are characterized by low signal level and severe multipath conditions. This inhibits the ability to accurately detect the time of arrival (TOA) of the DLOS path between transceivers. For TOA measurements, an error in the detection of the DLOS path results in error of the position estimate. These position errors prevent traditional geolocation systems from achieving the location accuracy and system reliability required for military and homeland security applications. Innovative Wireless Technologies (IWT) is proposing an ultra-wideband (UWB) system. The project will combine IWT's existing knowledge in ad-hoc UWB communications networks and hardware prototyping with industry leading research in indoor positioning to develop innovative geolocation algorithms that take advantage of the multipath-resistant characteristics of pulse-based UWB. System requirements and architecture will be evaluated and innovative geolocation algorithms developed. Tradeoffs between the number of nodes in a network and location accuracy will be determined through propagation channel measurement and characterization.

Title:Innovative Methods for Geolocation and Communication with Ultra-Wideband Mobile Radio Networks
Abstract:Multispectral Solutions, Inc. (MSSI) proposes to develop a frequency agile Ultra-Wideband (UWB) Radio Frequency (RF) front end for an integrated geolocation and communication network. UWB receivers have extremely wideband RF front ends that are vulnerable in hostile electromagnetic threat environments. A frequency agile UWB RF front end will enhance the Low Probability of Interception and Detection (LPI/D) and anti-jam (A/J) capabilities of advanced communications networks. MSSI will develop requirements and architectures based upon approved scenarios and will examine different frequency agile filter requirements and will develop an appropriate design. The design will consider several potential architectures and the front end will ultimately be integrated into MSSI's geolocation and communication network system. MSSI will demonstrate the ability to operate a dual function simultaneous digital ranging and communication device. The device will provide inter-node ranging while broadcasting voice packets over the same physical layer. Based upon the results of the systems study, and demonstration, MSSI will summarize the results with in a final report. Under the Phase I option and Phase II the resulting hardware will be transitioned into field demonstrable systems.

Title:WIDE BAND HIGH FIDELITY DRFM (HIFID)
Abstract:SPEC will develop a Wide Band High Fidelity Digital RF Memory designated the HiFiD. HiFiD supports generation of multiple high fidelity simulated targets for long range radar sensors and is innovative for future airborne target simulator applications. System provides high fidelity generation of multiple simultaneously delayed replicas of arbitrarily complex radar waveforms with very large instantaneous bandwidths (1-2 GHz). HiFiD will have 4 channels expandable to 16, each having an independently dynamic time delay and Doppler frequency offset. SPEC will develop the HiFiD prototype design favoring proven commercial off-the-shelf (COTS) technologies to minimize technical risk and achieve cost savings. Using existing SPEC DRFM technology, as a baseline, ensures cost effective, reduced risk HiFiD development. HiFiD development program uses existing process and analysis protocols to identify system components, develop technical specifications, and model/predict performance of the system identifying constraints/critical components. Existing computer/laboratory models support theoretical investigations to assess feasibility and practicality of the proposed system design. Leveraging existing DRFM technology significantly reduces HiFiD development technical risk and cost. Although this proposal leverages other DRFM technology, many differences in details of the HiFiD system as bandwidth, number of channels, maximum delay time, Doppler resolution and attenuation require significant innovation.

Title:Advancing the Objective Force Through Mulitnational Coalitions and Interagency Task Forces
Abstract:The proposed effort aims to develop a system that is responsive to the military's needs to develop high performing multinational teams. The goal of the project is to develop a theoretically grounded, computer-based, multination team preparation system. We envision four interrelated components forming the basis of a multinational coalition team preparation system. This system will support both individual and team training methods through use of asynchronous (individual) and synchronous (team) interaction modes. Multicultural and multinational team familiarization will be based on current team theory and is a method to educate team members about the nature of multination teamwork. A warfighting-peacekeeping continuum awareness section will apply lessons learned from recent military activity and the project team's own experiences in Bosnia to prepare soldiers for the information, resources, situations, and decisions they will face and develop appropriate adaptation mechanisms. Teamwork skill development will enhance individuals' ability to perform in a team setting. Finally, collaborative scenario based team preparation is a team-in-the-loop environment that will develop high performance multinational coalition teams. In Phase II, we will operationalize system requirements and develop a system to enhance multinational team performance in military and commercial environments.

Title:Increasing the Effectiveness of Multinational Peacekeeping Teams through Web-Based Assessment Technology
Abstract:This proposal describes an innovative online set of tools that the U.S. Army can utilize in its effort to understand how cultural differences impact the effectiveness of its multinational peacekeeping teams. In this proposal Meridian Resources Associates proposes to assist the U.S. Army in leveraging the diversity of its multinational peacekeeping teams around the world through the use of two research-based web assessment tools. Meridian's approach in Phase I would be to adapt our Global Teams Online assessment tool to the unique aspects of the U.S. Army teams. This would be accomplished through the implementation of the existing survey with a limited number of teams and a series of interviews with experienced peacekeepers from a wide range of countries. In addition, Meridian would survey a broader set of global team members using an online Self-Assessment Profile. This tool is designed to measure differences in work style preferences between people from different countries. The data collected here will help raise awareness regarding cultural differences and prepare team leaders and members working on multinational teams in the future.

Title:Advanced Composites for Ammunition Protection and Crew Survivability
Abstract:Battlefield vehicles such as the Interim Armored Vehicle (IAV) and Future Combat Systems (FCS) carry high energy, large caliber munitions into combat. The munitions are stowed in a rack within the vehicle and are susceptible to burning, detonation, and explosion when impacted by spall fragments occurring when the vehicle wall is penetrated by small arms and medium caliber projectiles. A need exists to protect the munitions from these effects, reduce the probability of detonation and explosion, and increase crew survivability. Fiber reinforced composite materials have been used successfully for both ballistic armor and thermal protection systems. With nearly 35 years of composite experience for both applications, Fiber Materials, Inc. proposes an engineering design and modeling effort to determine the feasibility of combining fiber reinforced, fire retardant composites to provide ballistic impact and fire thermal protection in a single material. The study will include S2r-Glass and/or Kevlarr fabric in a matrix of FTR 402 fire retardant resin. The design options include separate structures to provide protection for the munitions rack and for individual munitions casings. The ballistic/thermal protection designs will be submitted for ballistic impact modeling and the predicted thermal response of each design.

Title:A Nanocomposite that Can Best Lexan in Tranparent Armor Properties
Abstract:In 1996 Shell Chemical discovered a set of tough copolymers of CBDO monomer. These materials have Tg­s to 205›XC and notched Izod impact strengths over 1000 Joules/meter (Lexan: 128 J/m). CBDO copolymers are optically transparent, with a yellowing index less than Lexan. It is the impact strength of these materials that make them uniquely suited to use in transparent armor, and that will allow for reductions in thickness and weight. Using molecular modeling CBDO copolymer nanocomposites will be designed and subsequently fabricated in the laboratory. By forming nanocomposites of CBDO copolymers and tailoring the CBDO:PDO ratio, ballistic resistant sheet will be produced. The sheet will be formed into laminates containing an EMI resistant layer with 30­V80 dB spectral attenuation. Base Phase I laminates will withstand National Institute of Justice (NIJ) level IIA firings, and achieve level IIIA (most powerful 9 mm weapons) in the Option period. Phase I culminates with certified NIJ IIIA testing at H.P. White Labs. A transparent armor company is teamed to provide test services, laminate design assistance, marketing input, and a potential commercial buyer of sheet format transparent CBDO copolymer nanocomposites. During the patent transfer to SMRC subcontractor SWT, Shell estimated CBDO copolymer cost $1/lb.

Title:Novel Hierarchical Multilayer Laminated Plastic Structures (1000-332)
Abstract:In light of recent terrorist activities, there is a need for new materials/process technologies that can provide not only armor enhancements for military vehicles, helicopter and aircraft canopies, improved personal protective equipment for US marines and improved shipboard damage control, but also fire protection and EMI shielding. The use of polymer based materials in several of these applications has increased over the years, driven mainly by desirable properties, ease of processing, light weight and low cost. Triton Systems Inc proposes an innovative strengthened lightweight transparent multi-layer (hard/ductile) laminated plastic structure for enhanced ballistic resistance, with highly conductive coatings (organic and inorganic) for added EMI shielding capabilities. A single structure with all the above properties is lacking in current systems. These unique nanocomposite materials will serve numerous applications, military and commercial markets, viz., aircraft windows, helicopter and aircraft canopies, impact resistant building windows, safety goggles, face shields for soldiers, and public transit windows.

Title:Non-Imaging Disposable Sensor System
Abstract:The proposed SBIR will develop a Disposable Unattended Ground Sensor System that has the performance characteristics of much costlier systems. McQ has defined a design approach which can meet the small size and ten dollar cost goals needed to consider the sensors as disposable. McQ has over ten years of experience in designing state of the art remote sensor systems and successfully commercializing them for a variety of applications. McQ will apply this experience to tradeoff performance and cost issues needed to realize a disposable sensor system that effectively detects targets while keeping the cost at a level the individual sensors can be used as disposable units. McQ will develop a disposable sensor system design in the Phase I effort and evaluate the performance versus the cost to produce in quantity. McQ will provide a Phase I design presentation after four months. McQ will provide a formal Preliminary Design Review in a proposed SBIR Option Phase after an additional two month effort to bridge the work leading toward a Phase II SBIR contract. McQ will develop and demonstrate the disposable sensor system in a Phase II effort.

Title:Cross-Layer Designs for Energy-Efficient Sensor Networking
Abstract:We propose a novel architecture for large-scale, low power sensor networks, referred to as Sensor Networks with Mobile Agents (SENMA) utilizing an Ultra Wide Band physical (PHY) layer. SENMA is designed to exploit node redundancies by introducing mobile agents that communicate opportunistically with a large field of sensors. The addition of mobile agents shifts computationally intensive tasks away from primitive sensors to more powerful mobile agents, which enables energy efficient operations under severely limited power constraints. Additionally, we select the Ultra Wide Band PHY layer to exploit mutual non-interfering operation and its natural by-product of range information. We further propose a cross-layer approach of PHY and MAC layers to provide power efficiency and operation effectiveness over SENMA architecture, referred as an Opportunistic ALOHA. Finally, using randomly selected CDMA codes from a large table of orthogonal codes will further reduce the complexity associated with collision mitigation. A comparison and analysis of SENMA with a flat ad-hoc sensor network architecture will be comprehensively conducted regarding the energy efficiency.

Title:Human Behavior Architecture Interface for Integrated Cognitive and Task Performance Model Development
Abstract:As the Army transforms itself into an organization of the future, emphasis on acquiring new military systems and training soldiers to use those new systems is a primary challenge. These transformation programs are also counting heavily on simulation-based acquisition and training as a means through which risk can be minimized and total ownership cost can be reduced. To truly evaluate aspects of human behavior that impacts system performance, we need to model how soldiers will perform the perceptual, cognitive, and physical tasks required. However, a human behavior modeling environment that includes both procedural and cognitive aspects of human behavior does not currently exist. In addition, the available cognitive modeling architectures are difficult to use and require expertise in programming, modeling, and cognitive science. This proposal outlines a work plan for developing a modeling environment that consists of task network discrete event simulation and a cognitive architecture in a unified and integrated package. The unified architecture is designed to be used by systems engineers, analysts, and human factors professionals without backgrounds in programming or cognitive science to evaluate proposed new systems and to provide realistic training experiences through development of semi automated forces that behave more realistically.

Title:Compact Absorption Cooling Cycle Apparatus for Exhaust Gas Water Recovery
Abstract:Supplying potable water to troops in the field is a significant hurdle requiring complex logistics and specialized equipment. Operational units already have an untapped source of water in the exhaust from their engines. The challenge is to efficiently cool the exhaust below the dew point and condense the water vapor. CFDRC proposes the development of the absorption cooling Diesel Exhaust-Water Recovery System (DEWRS). The system utilizes rejected heat in the exhaust gas stream to drive a thermodynamic cycle that cools the exhaust gas and condenses the water vapor. The cycle circulates liquid refrigerant, which provides the advantages of using a small pump, and offers flexibility in system arrangement. Parametric thermodynamic system analysis will examine the applicability of both LiBr/H2O and H2O/NH3 absorption cycles. A 1-D system model will be developed to simulate the engine-DEWRS integrated system operating under a variety of duty cycles. Additional detailed analyses will be performed to support the design of system components, including the use of Genetic Algorithms for optimization. During Phase 1, our efforts will focus on developing a prototype system compatible with the single cylinder Caterpillar (3400 Series) diesel test engine at the University of Alabama IC Engine Test Center.

Title:Novel Combined-Cycle Turbine Engine with Water Harvesting
Abstract:A novel combined-cycle turbine engine with water harvesting capability is proposed for development into a commercialy viable product. The semi-closed engine and combined absorption refrigeration cycle is ideally suited to water extraction from the exhaust. Water extraction occurs in a portion of the cycle that has high pressure, low temperature and a near-stoichiometric exhaust stream, all of the conditions neccessary for optimum water yield. In addition, the proposed engine cycle has a low thermal signature due to low temperature exhaust and ultra-low emission of NOx and CO. The cycle has high efficiency and high power density. The proposed Phase I effort features analysis, design, and experimental testing to determine the viability of the combined cycle. An existing analysis code of the combined cycle will be modified to accomodate the water extraction bookkeeping. An existing test engine with exhaust recirculation will be used to demonstrate water extraction at atmospheric pressure. Additional work will include a component matching analysis and a water extraction hardware design component. Testing will be performed at an existing facility at the University of Florida. Analytical and design support will be provided by Concepts NREC.

Title:True Time Delay Multiple Beam Antenna System Design Tool
Abstract:The current generation of field simulation codes are powerful design tools that are highly accurate and can solve small to moderately sized problems. For multi-wavelength structures the options are limited. Examples of application areas where one would find such structures include Rotman lens design, IC package design, and electromagnetic compatibility simulation. As the demand for higher performance designs increases in these industries the need for a CAD software package that can analyze these geometries also increases. In addition to being able to simulate larger geometries it is also important that such a tool be easy to use with a user friendly GUI and have robust model translation. We purpose to extend the analysis capabilities of Ansoft HFSS to be able to simulate large multiple wavelength structures. HFSS has a user friendly interface and accurate simulation engine. We purpose to enhance that engine to allow it to efficiently simulate both electrically large and small geometries and to implement further improvements to the user interface and model translation tool.

Title:True Time Delay Multiple Beam Antenna System Design Tool
Abstract:Accurate analysis of multiple wavelength structures which contain regions with fine details is a challenging problem. A full wave method such as the Finite Difference Time Domain method can be used to analyze large structures as long as enough computer memory. High frequencies ray methods are often used for cases where the structure is very large in terms of wavelengths. In the case of an antenna system that includes transmission lines, a beamforming element such as a Rotman Lens, and an array of antennas, a hybrid approach allows a full wave method to be used to solve the complex field interactions on the feed section of the beamformer and around the antenna array while a high frequency method could be applied to the lens section to accurately simulate the field interaction with the complex surface. Even more useful would be an approach that incorporates CAD design elements and some form of optimization as well to allow the best system to be configured and saved in an appropriate format for fabricating a the actual components. The development of this fully hybrid solver with CAD editing capabilities and some form of design optimization will be the main focus of the proposed effort.

Title:High Energy Density, Fast-Rise Film Capacitors
Abstract:The object of this proposal is to demonstrate the feasibility of two new film capacitor approaches to meet Army high-energy capacitor requirements. One is a new type of metallized polypropylene capacitor that already exceeds the Army energy density goal. The other is a new metallized polyvinylidene fluoride (PVDF) capacitor technology that has the potential to increase energy density by another factor of three. Phase I includes experiments with both types of capacitors to evaluate their capability to meet Army capacitor requirements for energy density, rise-time, pulse repetition rate and lifetime. Based on the test results, and working in collaboration with a capacitor manufacturer and a film manufacturer, we will develop a plan to produce full-scale capacitors for the Army and make specific recommendations for development in Phase II.

For the proposed effort TRS and Prof. Qiming Zhang of Penn State will fabricate wound prototype capacitors from terpolymer film and test them for energy density, equivalent series resistance, insulation resistance, and charge/discharge speed. The goal for this program will be to demonstrate a 0.1 to 1 microFarad, 5 J/cc wound capacitor with a discharge speed faster than 10 microseconds.

Title:Mixed Signal MMIC for 10GHz Multifunction Frequency Syntheses and Modulations
Abstract:This proposal presents an innovative, affordable, and feasible architecture of frequency synthesis and modulation based on SiGe high-speed MMIC designs. The architecture includes an ultrahigh-speed direct digital synthesizer (DDS) with a maximum clock frequency of 10GHz to synthesize and modulate the intermediate frequency (IF) of 1GHz and above. It uses a low-noise phase lock loop (PLL) to generate both the DDS clock and the carrier frequency of 10GHz and above. The PLL synthesizer includes a quadrature voltage controlled oscillator (VCO) to generate the quadrature carriers without using a high loss and narrow-band poly-phase network. The high-speed DDS includes a patent pending high-order delta-sigma noise shaper and a sinusoidal weighted digital-to-analog converter (DAC) with 15-bit resolution to achieve better than -60dB spectral purity. The cosine weighted DAC eliminates the sine and cosine look-up table, which is a speed and area bottleneck for high-speed DDS implementations. The DDS modulation waveform configurations include chirp, step frequency, FM, MSK, PM, AM, QAM, and other hybrid modulations. The modulated IF frequency is mixed with the carrier frequency using quadrature mixers with image rejection. The proposed architecture can be implemented in high-speed SiGe processing. Some critical blocks have been implemented and fabricated using IBM 5HP SiGe.

Abstract:TelASIC Communications is pleased to submit an SBIR proposal for the Mixed Signal for Multifunction RF (Radio Frequency) Sensor. This proposal includes the investigative study of the development of a flexible and affordable digital synthesis approach capable of generating waveforms for high range radars and low probability of intercept communication applications. TelASIC is proposing to investigate the highest level of integration on a single chip. TelASIC is proposing to explore the feasibility of a novel RAM/ROM hybrid delta-sigma DDS (Direct Digital Synthesis) with multi-bit DAC on a single chip. Two versions will be considered: The first will clock a multi-bit DAC at greater than 20 GHz for a Nyquist of greater than 10GHz, and the second version will have a higher resolution DAC upconverted to greater than 10 GHz. The feasibility of the multiplexed DAC clocked at greater than 20 GHz and capable of synthesis at carrier frequencies over 10 GHz with 1 GHz of instantaneous modulation bandwidth, using the IBM SiGe 7HP or 8HP BiCMOS processes, will be investigated. In addition to the ultra high speed bipolar capability, special considerations will be given to maximize the utilization of the advanced CMOS in the SiGe BiCMOS, DRAM and SRAM for a low power and low cost monolithic solution.

Title:An Efficient and Accurate Calculation Procedure for Atmospheric Radiation Transport
Abstract:This Phase I SBIR project is aimed toward the development of a novel computational procedure that will allow accurate and fast prediction of radiative fluxes and transmission losses within the earth's atmosphere. The proposed calculation procedure is expected to be several orders of magnitude faster than the currently used very-narrow-band models in MODTRAN (or MODR), with accuracy comparable to that of line-by-line (LBL) calculations. The calculation procedure will be based on the recently developed (Michael Modest, Penn State University) full spectrum correlated-k distribution (FSCK) model, which allows accurate and superfast prediction of radiative fluxes in a medium comprising of participating molecular gases. This novel method is exact for homogeneous paths and its accuracy for inhomogeneous paths depends on the scaling technique (similar to the Curtis-Godson approximation) used for the absorption coefficient. The model has already been implemented in the commercial code CFD-ACE+ for combustion applications and validated extensively. In this project, we propose to demonstrate the feasibility of using this state-of-the-art model for atmospheric radiation calculations, pending required modifications and enhancements. To prove the feasibility, comparisons will be performed against LBL calculations to judge accuracy, and against MODTRAN and other narrow-band-model codes to judge speed.

Title:kURT, k-distribution based Ultra-fast Radiation Transport
Abstract:Design of electro-optical sensors for military and commercial use increasingly relies on scenario simulation models. It is critical these models yield accurate transmittances and at-sensor radiances, and be extremely computationally fast to allow robust sampling of the multi-dimensional design parameter space. Spectral Sciences, Inc. proposes to develop a sensor bandpass tailored RT model, dubbed kURT (k-distribution based Ultra-fast Radiative-Transfer). kURT features a new and innovative method for combining fine spectrally gridded MODTRAN4 k-distributions into a compact and accurate k-distribution for an entire and spectrally-broad sensor bandpass. This provides bandpass transmittance and radiance calculations that are faster by a factor of 100 or greater than MODTRAN4. In Phase I, MODTRAN-generated k-distribution databases will be created for 3-5 micron and kURT modules developed for generation of sensor band k-distributions and prediction of ultra-fast transmittances. These results will be compared to integrated 1 cm-1 MODTRAN4 predictions to determine if kURT meets the requirement for agreement to within 2% in transmittance. In Phase II, the kURT spectral range will be extended for UV through LWIR applications, and the kURT approach generalized for calculation of thermal and solar radiances.

Title:Agent-Based Knowledge Enablers for the Unit of Action
Abstract:The Army's Unit of Action (UA) is part of a joint team that is decisive in any operation, against any level threat, in any environment. This team must be strategically and operationally responsive, and be able to change patterns of operations faster than the enemy can respond. To meet these goals, it relies on the fusion of information from the Battlefield Functional Areas (BFAs), as well as disparate data from joint partners. In this research, the DAC Team will design and implement an intelligent agent toolkit for Network Centric Warfare that enables data from disparate information sources to be translated, coordinated, and fused in such a way that commanders can better respond to the Commander's Critical Information Requirements associated with a UA. This objective will be realized through three major activities: 1) developing techniques that overcome the heterogeneity of different data sources and represent them in a common ontology, 2) designing and implementing the collaborative agent architecture, and 3) specifying and implementing the interactions between agents in a way that enables critical information to be fused and subsequently presented to the commander.

Title:Agent-Based Knowledge Enablers for the Unit of Action
Abstract:As the vision of Network Centric Warfare (NCW) becomes reality in the Future Force, it is clear that trading steel (platform survivability) for information represents a true revolution in military affairs. A principal set of goals is to eliminate archaic information stovepipes, speed the flow of information to the end user, and rapidly increase the rate at which data is transformed into militarily significant and decision-centered information. Improving a commander's ability to collect, process, manage and answer the critical information requirements (CCIRs) associated with a Unit of Action (UA) provides a uniquely challenging opportunity. Given the risks of information overload and high workload, the goal of this system is to assist the commander in a commander-driven, purpose-oriented, knowledge-based fashion. This capability will allow for a continuous, evolving, and collaborative process that will reduce information and cognitive overload, increase the number of options considered, and reduce the time and effort spent planning while simultaneously improving decisions. We propose to combine state of the art techniques in multi-agent service-based cognitive architectures, knowledge abstraction layers semantically organized into ontologies, and intelligent user interfaces to create a system that will demonstrate how information age transformation can enable fundamental improvements to CCIR monitoring in NCW.

Title:Agent-Based Knowledge Enablers for the Unit of Action
Abstract:Unlike the past, modern conflicts are increasingly regional and asymmetric. This has prompted the Army to transform to Future Combat Systems (FCS) via an Objective Force - responsive, deployable, agile, versatile, lethal, survivable and sustainable. Strategic Manuever is key to this force - the rapid projection of military power. Given the available airlift and sealift, this requires the Army to "trade ... steel for ... information:" the lethality and survivability of current platforms is replaced by integration where interoperability ensures component lethality and survivability. Key enablers supporting this shift are Information Dominance via Network Centric Warfare (NCW). However, NCW advantages are often negated by Information Overload - an inability to separate the useful information from the mass of available data. Evolving Army doctrine includes techniques to help mitigate this overload. Among them are the Commander's Critical Information Requirements (CCIR), defined by the Commander as a decision-making aid. Useful CCIR overcomes overload by identifying what is most mission-critical. In a NCW environment, aids implemented via software agents are desired for their mobility and potential for intelligent action. Technology Service Corporation (TSC) will apply mobile software agent technology to the generation of CCIR within the organizational structure of an objective force Unit of Action (UA).

Title:REAL-TIME NATURAL HEARING DEVICE FOR ENCAPSULATING HEADGEAR
Abstract:Protective helmets anticipated for the next generation Army soldier (Objective Force Warrior) will provide superior ballistic and biological protection by encapsulating the entire head. However, such an encapsulating design will limit the soldier's ability to effectively hear the surrounding acoustic environment, limiting the soldier's effectiveness. The design and development of a fully encapsulating ballistic helmet with real-time acoustic field monitoring is proposed. The primary goal of the Phase I effort is to demonstrate the proof of concept of accurate hearing and localization through development of an encapsulating helmet prototype. The technical objectives and work tasks focus on intensive data collection followed by an exhaustive mathematical investigation of the optimal sensor/transducer placements to provide the most realistic hearing capabilities. Finally, the optimal compensation solution will be implemented and tested during the Phase I effort for both quantitative and qualitative performance verification. The multi-disciplinary approach required by the proposed design is facilitated by a strong technical team. Together ATI and Virginia Tech possess all of the expertise, hardware, and facilities required to effectively investigate this problem. The team assembled for Phase I, and anticipated for Phase II, includes experts in human perception of audio, mechatronics, digital audio design, controls, and signal processing.

Title:Polymers for Lightweight Small Arms Cartridge Cases
Abstract:Currently, small caliber cartridge cases are manufactured from brass. Because brass is a critical material, spent cartridge cases must be retrieved from firing ranges, which is time consuming and costly. The motivation to develop a polymer cartridge case is therefore primarily cost based, as it will remove the need for salvage, and will also reduce the cost of manufacture, by employing standard plastic molding techniques. It has also been demonstrated1 that polymer based casings will offer the following advantages: Increased Energy Transfer to the Projectile; Reduce Heat Transfer to Chamber; Reduced Muzzle Flash; Improved weapon feeding; Easier removal of ruptured casing; Reduced weight load for soldiers. The objective of this proposal is to investigate the use of certain some novel thermoplastic cartridge shell casings for small caliber ammunition. These chosen termoplastics have glass transition temperature in excess of 1500 C, moisture intake at saturation of less than 3% and tensile modulus variation of less than 15% over the temperature range from -550 C to 650 C.

Title:Polymers for Lightweight Small Arms Cartridge Cases
Abstract:The modern U.S. Army warfighter is being tasked to carry additional gear into the field to enhance combat effectiveness with the penalty of an increased weight burden. Recent improvements in polymer material technology and manufacturing processes that would allow a lightweight polymer to be used as a cartridge case material would help alleviate a portion of this weight burden. Polymer materials are 5 to 7 times lighter than steel or brass and half the weight of aluminum. Polymer materials have additional benefits compared to metals such as long storage life with no corrosion, potentially lower material and fabrication costs, and potential improvement in insensitive munitions performance. Texas Research Institute Austin, Inc. proposes to develop a lightweight, low cost, corrosion free polymer cartridge for small caliber ammunition that will function reliably in existing weapon systems and be capable of surviving the loads, pressures and temperatures experienced during the ballistic cycle. A polymer 5.56mm cartridge case will save over 1 lb of weight for every 100 rounds of ammunition compared to an equivalent brass cartridge case. This reduction in weight will allow U.S. Army soldiers to carry additional ammunition, or other equipment and supplies onto the field.

Title:Field-deployable, Reformable Tooling System for Repair, Replacement or Prototyping of Composite Structures
Abstract:The use of reformable, reusable tooling can greatly reduce the time, cost and skills required for conventional tooling production, and no waste products are generated since the tooling materials themselves can be rapidly cycled from a hard tooling-capable state to a liquid-like state and back to the tool-capable state. We are proposing to create a new, lightweight, rapid tooling system for prototyping, field repair and depot-level manufacture / re-manufacture of composite components and structures. The proposed fieldable system will be based on a new class of low density state-change materials and on the development of a robust lightweight system that operates a new type of single-faced reformable "toolbed." The new materials, toolbed design and activating system will be mounted in a field-transportable tooling package proposed for development through this program. In the program's Phase III stage and beyond, the system will be further developed into a fieldable "manufacturing cell" for composites fabrication through the incorporation of features for vacuum debulking and vacuum bagged, temperature-regulated cure of parts.

Title:Breathable, Chemically Resistant Materials for Protective Clothing
Abstract:Luna Innovations proposes to develop a cost effective, elastomeric material for lightweight breathable chemical protective clothing. Materials currently used for chemical protective clothing are either impermeable, leading to heat exhaustion, or based upon a permeable, absorptive technology, which is expensive and heavy. The proposed program involves 1) producing block copolymers based on poly(isobutylene) and an ionic segment 2) converting the block copolymers into an aqueous dispersion 3) casting films to demonstrate sufficient water permeation for breath-ability, resistance to chemical agents and mechanical properties necessary for use with flexible textile materials. The proposed elastomer is based on chemistries that can be readily scaled to produce large quantities for field testing and eventual commercialization. In addition, Luna has identified methods of making films from environmentally sound aqueous dispersions saving on the cost of handling, processing and waste disposal. This development will contribute to the Army's goal of producing clothing to protect personnel from lethal chemical agents while maintaining the comfort of the wearer.

Abstract:The objective of our research proposal is to design, synthesize, fabricate and evaluate economical and lightweight breathable, chemical resistant, elastomeric protective composite fabrics suitable for use in chemical agent protective garment applications. Our primary focus will be on developing breathable membranes that allow for water vapor to be transported away from the body, while simultaneously blocking penetration of harmful substances in liquid and vapor form. New fabric technologies suitable for military combat will also be evaluated in parallel along with the most effective methodologies for combining the breathable membranes with these fabrics to create a composite fabric system suitable for use in chemical and biological protective materials applications. These materials and methodologies will be identified, defined and evaluated during our Phase 1 efforts. Phase 2 efforts will involve making pilot and pre-production quantities of selected composite fabrics for testing and evaluation as chemical and biological defense garments.

Title:Long Wave Infrared Acousto-Optic Materials:Development of Novel Materials for the Fabrication of LWIR (8-12 micron)Acousto-optic Tunable Filters for I
Abstract:We propose to develop novel anisotropic materials that can be used to fabricate acousto-optic tunable filter (AOTF)-based spectral imaging systems in the LWIR (8 to 12 micron) spectral region. AOTF's are very attractive for multispectral and hyperspectral applications such as the detection of targets, backgrounds, and stand-off chemical and biological agents. Tellurium dioxide (TeO2) is the most commonly used AOTF material, and it has a spectral transmission range of 0.35-5.0 micron. However, chemical agent infrared absorption/emission primarily occurs in the 8-12 micron wavelength region. Currently, there is no technologically matured material for AOTF imaging in this wavelength range. Thus, we propose to investigate the mercurous halides (Hg2Cl2 and Hg2Br2) and tellurium (Te) for this purpose. These materials can be processed at relatively low temperatures, are nonhygroscopic, have high acousto-optic figure of merit (M2), high birefringence and relatively high transmission in the 8-12 micron spectral range. This long wave infrared (LWIR) region technology is relevant to the detection of buried mines and is an essential part of achieving the goals set forth in the Army's Third Generation Science and Technology Objective (STO).

Title:Ultra-Compact Doppler LIDAR (Light Detection and Ranging) for Unmanned Aerial/Ground Vehicles
Abstract:The rapid development UAVs and UGVs for the Future Combat System is producing requirements for remote sensing of volumetric winds and wind hazards such as wind shear, gusts, and clear air turbulence for safe and efficient vehicle operation. Mission specific parameters such as aerosol plume detection and tracking, terrain mapping, and helicopter rotor turbulence detection must also be measured. The UAV/UGV operating environment requires any operational sensor to be optimally compact, light-weight, and have low power consumption. In Phase I, CTI will develop requirements, specifications, and a system design for a UAV/UGV coherent Doppler Lidar system, focusing on modularity, compact size, and low power consumption. CTI will then leverage from previous work to demonstrate a novel agile-pulse laser technology, with electronic switching between a short-pulse mode for high-resolution terrain mapping with a 10-ns pulsewidth, to a long-pulse mode for wind sensing with pulsewidth electronically adjustable in the range 100 to 400 ns. This agile-pulse capability will allow a single laser to be electronically configured for optimal measurement of a parameter. In Phase I, CTI will also demonstrate a unique proprietary lidar cavity, which will allow small, light-weight, reliable, and rugged transceivers to be built. The agile-pulse laser and the cavity architecture will form the foundation for the ultra-compact Doppler lidar for UAV/UGV. In Phase II, the design for a prototype sensor will be completed. The prototype sensor will then be fabricated, tested, and a performance analysis conducted.

Title:Ultra-Compact Doppler LIDAR (Light Detection and Ranging) for Unmanned Aerial/Ground Vehicles
Abstract:The availability of moderate power fiber lasers and amplifiers has made possible the demonstration of compact Laser Radar systems in the eye safe spectral region. These systems benefit primarily from the high repetition rates afforded by the ideal thermal management in optical fibers allowing very good optical beam and pulse fidelities. For un-manned airborne vehicles to become cost effective and have reliable performance they will require avionic systems for landing and take-off that will be insensitive to sudden weather changes. As a result a compact and rugged solution with a low entry cost is required to limit the number of crashes at landing and take off of UAVs. Under this SBIR we propose to demonstrate a multi-purpose (Doppler-DIAL-DAS), compact coherent detection system that will eventually be tunable in the important eye safe spectral range. This range is relevant for both air and ground vehicles since it affords relative eye safety. In particular we will demonstrate the feasibility of detecting wind-shears and simultaneously perform differential absorption measurements with an all-fiber based transmitter-receiver system. This approach will result in a compact, cost competitive Doppler Lidar system.

This system will interface to the MUVES-S2 modeling suite. Integration of this system will involve several specific tasks. A hardware system will be defined to measure and capture blast response. A transducer location and data analysis strategy will be identified to best relate measured acceleration data to equipment fragility. A strategy for defining equipment fragility will be identified. Utilizing these tools software will be developed to interface the data into the MUVES-S2 suite so as to provide blast definition in terms of equipment fragility thresholds.

Title:A Novel Heavy Traffic Approach to Stochastic Optimal Control of Mobile Communications
Abstract:Balancing high throughput with head-of-the-line wait time for queued data requires explicit stochastic process modeling of the time variations of the channel and the complex queuing process. However, such process models are too complicated for a direct solution. In this proposal, Intelligent Automation, Inc. (IAI) and its subcontractor, Prof. Robert Buche of the North Carolina State University, propose a novel heavy traffic approach to optimal stochastic control of mobile communications. Under the heavy traffic assumption and scaling, one can arrive at a limit system described by a stochastic differential equation (with reflection and/or jumps), which approximates the actual system. Based on the limit system, we can obtain the control by using the powerful novel numerical methods originally proposed by Kushner and Dupuis. Some other advantages of the proposed stochastic control design approach include: First, the controls obtained from the heavy traffic analysis are effective in the practical system, even operating far from the heavy traffic regime. Second, the heavy traffic modeling is general enough to handle a variety of configurations including TDMA, channel estimation, etc. Third, the proposed admission control design is independent of power control. Fourth, the proposed numerical methods sound and it has been theoretically justified by the convergence proofs.

Title:Research and Development of Stochastic Optimal Control Algorithms for Mobile Communications Systems
Abstract:The overall objective of the effort (Phase I and Phase II) is to utilize Stochastic Optimal Control (SOC) techniques to derive and evaluate scheduling algorithms for Mobile Communication Systems. SOC techniques were recently employed to establish the optimality of the widely used Proportional Fair Sharing (PFS) scheduling algorithm under idealized conditions -- one single base station, unique service class and heavy traffic in all transmitters. This result provides an important link between well established SOC methods at one side and the practice of Mobile Communication Systems at the other side. We will use these developments as our starting point in Phase I, and investigate the possibility of extending these results when one or more of these assumptions are not met. Phase I will be focused in the scheduling problem only, using analytical techniques to: (1) investigate the performance of PFS under more general conditions, and (2) modifying PFS for improved performance. Limited numerical experiments will be performed to validate the theoretical developments. The most promising physical layer schemes derived in Phase I will be combined into a full protocol stack for High Rate Packet Data Systems in Phase II. We will focus our developments in the IS-856/CDMA2000 protocols, seeking the development of algorithms compatible with the emerging Third Generation Wireless Technologies. Northrop-Grumman Information Technology will be a subcontractor in the effort, providing expertise in the tactical operation of mobile networks. Professors Harold Kushner (Brown University), John Tsitsiklis (MIT) and Sanjoy Mitter (MIT) will serve as consultants, working with SSCI in the development of control theoretic methods for scheduler analysis and design.

Title:Mixed-Feed Direct Methanol Fuel Cell
Abstract:The Army's need for high energy-density, lightweight power sources gives incentive to the search for creative fuel cell concepts and approaches that can potentially reduce size, weight, and complexity. Success in such efforts would certainly have significant spin-off opportunities in the commercial sector, such as in medical devices, computer hardware, and recreational needs. The mixed reactant feed approach in direct-methanol fuel cells has attractive potential in light of the fact that it could reduce size and weight associated with fluid delivery devices, manifolding, and sealing. The proposed project is intended to explore the cell/stack and system design opportunities associated with mixed-feed, with the objective of laying the groundwork for substantial improvement in size and weight parameters for the system power and energy required. The overall technical goal is to meet the Army's size and weight requirements for a 20-watt, 1-kWh power source during Phase II. The objectives of the project are: a) to identify and deploy selective cathode catalysts/electrodes that demonstrate enhanced activity/performance in methanol-air mixed-feed fuel cell stacks and b) to investigate, optimize, and implement a novel stack design concept that yields substantially reduced size and weight in relation to those of conventional DMFC stacks

Abstract:Mesoscopic Devices proposes to develop an advanced direct methanol fuel cell generator using mixed reactant technology. Our approach combines an advanced compact mixed-reactant stack with a tightly integrated balance of plant specifically configured to take advantage of the unique characteristics of mixed-reactant DMFC stacks. The combination of the mixed-reactant stack with the innovative BOP design will allow simultaneous increases in the power density and reductions in cost. The proposed design is significantly simpler and more compact than conventional DMFC designs. In Phase I, the feasibility of the innovative approach will be demonstrated through fabrication of mixed-reactant stacks and design of a complete power generator including all components of the unique balance of plant.

Title:Catalytic Coatings for Chemical Protection
Abstract:The U.S. military must be prepared to operate in an environment contaminated by chemical warfare (CW) or biological warfare (BW) agents. Currently, chemically contaminated hardware is decontaminated either with the highly caustic and corrosive DS2 or with peroxide foam decontaminants. Either approach necessitates carrying sufficient decontaminant to forward bases, and therefore presents an additional logistics burden. Furthermore, even decontaminated items may retain some agent especially around seams, and in time the trapped agent may diffuse out of the coating (desorb), exposing soldiers to additional hazards and activating alarm systems. An ideal protective system would modify the surface of critical materials so that they offer protection from CW and BW agents at all times, with no additional operational or logistics burden. TDA Research, Inc. (TDA) proposes to develop a reactive coating to spontaneously detoxify chemical weapons under ambient conditions, focusing in Phase I on developing a robust catalyst for the hydrolytic detoxification of nerve agents, particularly agent VX. In Phase I we will synthesize new catalytic materials capable of detoxifying agent VX. We will then demonstrate that these new catalysts, and oxidative catalysts for detoxification of agent HD, can be incorporated into coatings as required for military vehicles.

Title:Detection of Drugs/Narcotics and Processing Components Using
Abstract:Seacoast Science proposes to fabricate a detector that meets all the requirements to serve as a system for sniffing out illicit drug processing laboratories. The system includes a chemical sensor array selective and sensitive to the volatile chemicals commonly used in drug synthesis, a radio for wireless communication and a small, rugged, lightweight, low-power system designed for long-term battery operation. Our MEMS chemicapacitor technology utilizes an array of surface micromachined capacitors, coated with chemoselective polymer coatings optimized for volatile chemicals such as ketones, alcohols and hydrocarbons. These and similar chemicals are commonly used in drug processing. Its exceptionally low power consumption, inexpensive production cost and robustness allow our detector to operate under battery power for up to 6 months. In Phase I we will test our sensors by exposing them to common drug processing chemicals at appropriate concentrations under a range of environmental conditions. This 6 month Phase will result in a demonstration of a detector package consisting of three sensor units that will be able to transmit concentration levels of chemicals wirelessly. Operationally these detector systems will be small enough to be used clandestinely at suspected lab locations and cheap enough for widespread distribution.

Title:Large Scale Biomaterial Production
Abstract:The engineering of food crops such as corn or rice to produce proteins has significant commercial potential. Very high levels of protein can be produced at a relatively low cost with a relatively long shelf life. In addition, for medical applications the use of cereal grains such as corn or rice as a source is deemed safe. Ceres has developed a system to enhance the production efficacy of proteins in cereal grain. Included in the system are expression amplification, pollen and progeny control systems and detection systems for rapid testing to verify the genotype. The system consists of two genetic components or lines, a target line and an activation line. The target line is male sterile, i.e. it cannot produce pollen. It will function as the female in a cross. The activation line is male fertile and expresses a transcription factor targeted to the desired cells, but no other foreign genes. It functions as the male in a cross. The target line contains the gene(s) of interest, a Ceres proprietary plant gene to make the progeny nonviable and a marker gene. Target genes are expressed, and target proteins are produced, only in the grain.

Title:Large Scale Production of Spider Silk by Immortalized Spider Cells
Abstract:Despite a decade of active research into cloning and expression of spider silk, no adequate solution has been found to the production of significant quantities of these proteins, especially for broader markets and materials applications. Two options that address the need for increased spider silk production, namely overcoming production limitations in engineered cells and scaling up production of low producing systems, do not offer sufficient advantages for further development. Foster-Miller, in collaboration with Tufts University, proposes an alternative approach that is based on generating stable cell lines that originate from silk producing spider glands via a spontaneous mutation process during continuous culture, viral transfection, and by telomerase immortalization. Retention of natural silk productivity in immortalized cells will be targeted. The proposed work for the Phase I base program involves generating and characterizing immortalized spider silk producing cells, producing a representative batch of silk protein solution, and evaluating properties of the protein excreted by spider cell lines. The technological parameters of silk protein production will be optimized in the option program. Nexia Biotechnologies, Inc., a world leader in the manufacture of recombinant silk proteins, has agreed to assist the proposing team in the commercialization of the proposed process. (P-030567)

Title:Cross-Layer Protocols for Energy Efficient Wireless Sensor Networking (CrossNet)
Abstract:The goal of this Phase 1 SBIR is to refine and evaluate an integrated cross-layer wireless networking protocol suite that spans OSI layers 2 (link) through 4 (transport) and reduces energy consumption in sensor networks. Early analysis suggests that an order of magnitude reduction in energy consumption over traditional approaches is achievable for typical UGS scenarios by combining services across layers. Our innovation combines novel extensions in link-layer MAC scheduling and hop-by-hop repair services with recent network layer research in minimum energy diversity routing. The link-layer services may also be used to control power modes of emerging radios for further cross-layer performance gains. In all, the combination promises to eliminate major sources of energy consumption including idle listening, control signaling, congestion hot-spots, and packet retransmissions due to channel errors. The approach leverages our existing sensor network simulation testbed developed under NSF funding to evaluate the energy, throughput, and latency performance against alternative solutions. The technology developed under this SBIR is anticipated to have broad application to army sensor networks as well as public commercial wireless systems and plant automation.

Title:Man Portable Personnel Detection Device for MOUT
Abstract:This project demonstrates the feasibility of fusing ultra wideband (UWB) radar and acoustic sensors to produce a high performing man portable personnel detection device for MOUT. Time Domain Corporation (TDC) has developed RadarVisionƒ, a commercially available, handheld, battery-operated, synthetic aperture UWB through-wall motion imaging device. This device rapidly indicates and displays sources of motion behind walls. An ongoing Air Force contract will deliver enhanced features needed for MOUT applications. UWB penetrates concrete, sheetrock, wood, plaster, tile and fiberglass, but it is blocked by solid metal and metal coated objects. Since acoustic energy does travel through metal, fusing a sonic sensor with RadarVision would provide additional capability to sense through metallic barriers. In this project, TDC will investigate how UWB-enabled radars and sonic devices operate independently in similar motion-detection scenarios. The company will fabricate, test and demonstrate an acoustic sensor testbed, define a prototype radar-sonic fused system, and predict fused sensor performance. If Phase I results show sufficient improvements in performance, in Phase II TDC will assemble and test an integrated, dual-sensor system for evaluation by DoD in MOUT scenarios. The sonic enhancement could also be incorporated into TDC's commercial product for use by law enforcement and search and rescue teams.

Title:High Power, High Efficiency Diode Sources for Pumping Eye-Safe Solid State Lasers
Abstract:High power eyesafe lasers are crucial for many military and industrial applications. Erbium doped lasers offer the potential for direct laser operation at 1.5 microns thereby reduces the size and cost and improving the efficiency of today' frequency converted one-micron lasers. Diode pumped Erbium lasers are typically pumped at 980-nm. The large quantum defect between the lasing wavelength and the pump wavelength leaves roughly 30% of the deposited energy as heat. For example, a 1-kW Erbium laser would require at least 500 Watts of heat to be removed. This amount of heat not only effects laser performance, it also requires a large thermal management system that adds size, weight, and cost to the system. A similar laser that was pumped at 1470-nm would require a factor of ten less heat to be removed. Unfortunately, today's high power InP diode lasers operating at 1470-nm produce less power and are less efficient 980-nm laser diodes. This is primarily a result of a dramatically lower differential quantum efficiency that results from both lower injection efficiency and higher optical losses. With a novel epitaxial structure we propose to improve the overall efficiency of high power 1470-nm InP based laser diodes to over 40%.

Title:Flexible UHF Chaotic Devices for Radar Applications
Abstract:We propose to develop ultra-high-frequency optical and electronic chaotic devices that offer great flexibility. In Phase I, we will design one optical and one electronic chaotic device whose central frequency can be adjusted in the range from 1- 50 GHz and the dimensionality can be adjusted from low (~3) to high (>50) values. We will develop mathematical models that incorporate the detailed characteristics of the device components that are crucial in understanding the high-frequency characteristics of the devices, delineate the nature of the chaotic behavior and how it depends on the device's characteristics, and specify manufacturing parameters. A unique aspect of the proposed devices is that the time scale and "complexity" of the chaotic waveforms can be adjusted over a wide range so their performance can be matched to a variety of applications. Recent progress at Duke University demonstrates the feasibility of controlling chaos in high-bandwidth systems even when the latency is comparable to the characteristic time scales of the chaotic device. Adjustments to our controller allows for controlling different UPOs embedded in the chaotic system, which could be used for symbolic-dynamic-based communication schemes. Such communication schemes possess inherent advantages for efficient use of bandwidth, and feasibility of robust encryption.

Title:Compact Submillimeter-Wave Sources and Detectors for Biological and Chemical Spectroscopy
Abstract:This SBIR Phase I project addresses the challenge of minimizing the size, weight and power consumption of a frequency domain THz spectrometer operating in the 0.3THz to 3THz range. Traditional solutions are larger and heavier than necessary since they rely on assembling optical sub-systems by using separately packaged commercial components, or by using general-purpose commercial grade optical mounts. Reducing the size and weight of a THz spectrometer will require advanced assembly techniques that are currently under development at Phasebridge and a small handful of other companies and research groups. This proposal makes the case that the design of the THz spectrometer should be relatively straightforward and can be accomplished in Phase I, and the advanced manufacturing techniques can be introduced in subsequent phases. The challenges in Phase I involve defining the system architecture and identifying the optical and signal processing components that would be part of the compact THz spectrometer system. A successful Phase I will fully establish feasibility of achieving these goals using Phasebridge's hybrid packaging technology. Owing to the mature state of the packaging technology at Phasebridge the prototype for Phase II can be built directly after the successful completion of Phase I.

Title:INTEGRATED COMPUTATIONAL ALGORITHMS TO TREAT FRACTURE AND FRAGMENTATION: Development of Software, Based on the Truly Meshless Local Petrov-Galerkin (M
Abstract:The objective of the proposed research and development is to develop integrated computational algorithms, and attendant software, to treat fracture and fragmentation of brittle as well as ductile materials, using the Meshless Local Petrov Galerkin nmethod, which is a new pardigm in computational mechanics. The object of Phase I is to develop a three-dimensional code based on the MLPG method. The code will be thoroughly validated through simulations of static and dynamic problems for which analytical and other numerical solutions exist. These problems include: The Boussinesq problem; The Eshelby problem; The problem of non-planar three-dimensional fatigue crack growth in an elastic-plastic solid; and The dynamic Hertzian contact problem

Title:Integrated Information Interface for Electromagnetic Modeling and Simulation Tools
Abstract:This work will extend and revise the design of the Computational Electromagnetic Framework to provide graphical user interface and pre- and post-processing capabilities to a variety of computational electromagnetic (CEM) software products for accurate and rapid design and prototyping for a variety of practical real-world DoD electromagnetic problems. Five Framework components are proposed: a model builder in which users describe the geometrical structure and have it translated into EM models; an application builder, in which users construct the "scene" to be simulated, complete with environment, sources, observables, geometries, etc.; a post-processor by which users format, manipulate, and visualize electromagnetic and engineering results, a database into which all models and results are restored and from which they are retrieved; and a Remote Software Management Console, from which a suite of CEM codes - perhaps residing on different computers - can be programmed, executed, and result retrieved.

Title:Integrated Information Interface for Electromagnetic Modeling and Simulation Tools
Abstract:Recent advances in electromagnetic algorithms such as the Multi-level Fast Multipole Algorithm (MLFMA) provide rigorous and efficient full-wave analysis of arbitrary PEC and dielectric structures with principle dimensions many wavelengths in length. This proposal is to take a suite of such algorithms developed under 6.1 ARO support at Duke University and wrap them in a common user interface that simplifies their use and provides a means for end users to script the user interface as well as underlying algorithms. The scripting interface is a key element that provides a capability sorely lacking in most Graphical User Interface (GUI) based scientific software built today - the ability for end users to extend an application's functionality beyond the features that were embedded by the original developers. This scripting capability will be integrated into an intuitive user interface designed by a team including electromagnetic experts, human-computer interface (HCI) specialists, technical writers, and experienced computer scientists. Together they will integrate state-of-the-art 2d and 3d visualization techniques with the best practices in UI design to deliver an application that supports the aggressive schedule for technology insertion into the Future Combat Systems for the Objective Force.

Title:Remote Neurological Measurement and Sensing
Abstract:This program combines state-of-the-art research into the determination of cognitive state and autonomic arousal with a recent breakthrough in electrophysiologic sensors. The sensor breakthrough enables accurate measurement of bioelectric signals without close contact to the skin, and opens up the possibility of a wearable (e.g. through clothing) sensor suite for operational environments. Additional data from respiration obtained via the Vivometrics "Lifeshirt" system, and conventional galvanic skin response, will be included. The goal of Phase I is to identify sensors combinations that can be used as inputs to algorithms (gauges) to assess cognitive state and cognitive capacity under high stress conditions. In Phase I we will project how well existing methods for determining cognitive state can be expected to work under conditions of high mental and physical stress. We will also measure the level of noise and artifacts when the candidate sensors are used on subjects undergoing high physical stress. In Phase II, a functional prototype including the sensor array and all algorithms will be demonstrated. The target configuration for the Phase II system is a small array of the new bioelectrodes mounted on the inside of a helmet with additional respiration and skin sensors as needed...

Title:SENSORS: System for Evaluating Neurological Stress with Objective and Remote Sensors
Abstract:The primary goal of this work is to develop an objective, wearable and robust medical data sensing and processing system, to remotely assess warfighter stress level and cognitive state. The experience of United States Army and much medical research show that types of neurological stress can greatly impede human performance, thus the Army seeks ways of reducing the cognitive workload on warfighters. During Research Development, Test and Evaluation (RDT&E) exercises, candidate military equipment and systems must be evaluated for how well they inform and facilitate warfighter decision-making during combat situations, and reduce stress and cognitive workload. Currently there is no objective means to evaluate cognitive state, nor therefore a human-machine interface. TIAX, in collaboration with Harvard Medical School and MIT researchers, proposes to research and build a medical sensor array worn by the warfighter during battle or simulation, to broadcast neurological data. Phase I will involve an interactive feasibility study of neurological measures and their supporting methods, followed by a Phase I option for systems integration and data reduction algorithms, leading to a Phase II construction of a system for warfighter use, and spawning Phase III commercialization of derivative products for critical staff monitoring, trucker alertness and lie detection.

Title:A Liquid-Crystal on Silicon Infrared Scene Projector
Abstract:This proposal outlines the research and development of a novel infrared scene projection system based on Liquid Crystal on Silicon (LCoS) technology. This technology combines the light modulating capabilities of liquid crystal with the compact, active electronics of VLSI circuitry. The result is a mass-producible, inexpensive, compact, low-power, high frame rate device. This proposal addresses the limitations of current visible LCoS-SLM technology in meeting the needs of an IR scene projector, and proposes an approach for the development of a multi-purpose VLSI backplane that is suitable for use in both the visible and IR. When combined with IR appropriate materials, the result is an inexpensive device that is reconfigurable.

Title:Advanced Visible-to-Infrared Dynamic Projector for Testing Imaging Sensors
Abstract:The Army is seeking development of an electro-optical/infrared projector for simultaneous testing of multiband suites of sensors - - visible, MWIR, FLIR, and LWIR. To meet this Army need, POC proposes to develop a new Advanced Visible-to-Infrared Dynamic (AVID) projector based on deformable surface elements placed over a MEMS chip. This device will project high-spatial-resolution dynamic scenes spanning the spectral range from visible to long wave infrared. The proposed AVID projector will have spatial resolution of 1240 x 1820, spectral bandwidth of 0.4-14 microns and amplitude resolution of 14 bits with variable dynamic range control. It will be flicker free, and sufficiently portable to operate on a mobile platform. The Phase I feasibility of the approach will be proven by simulation, followed by fabrication and testing of a working model. The Phase II prototype will have full functionality. This prototype will be the basis for several products and applications.

Title:Variable Aperture Cold-Stop for Multiple f-number Optics
Abstract:We propose to implement a simple continuously variable iris mechanism for operation at cryogenic temperatures. The iris is designed to function as a variable cold stop on an existing camera system in use by the Army Test and Evaluation Center (ATEC). The proposed device is based on a similar variable cold stops for SADA and pour-fill dewars that is under development by Opto-Knowledge Systems Inc. (OKSI) (this technology currently has patent pending status). OKSI's has the experience and ability to quickly move beyond the Phase I objectives, as defined by the ATEC solicitation, and begin addressing Phase-II goals in a relatively short amount of time. Under Phase-I we will develop and demonstrate a variable cold-stop for use with an existing camera in use by ATEC. During the Phase-I Option we will implement the variable cold stop in the same camera, and support the Army during a field test use of the new system. Under Phase-II we will address issues such as data collection and transfer rates, as well as, fine tune hardware items such as the optical train.

Title:Airspace Management and Deconfliction of Networked UAV
Abstract:ISX Corporation, in cooperation with SRI International, proposes a research effort to develop a UAV Airspace Management System (UAMS). UAMS will use advanced artificial intelligence techniques for airspace plan generation and repair in a network aware communications framework. UAMS will consist of 2 major components. One component, the UAMS Planner, will handle plan generation and monitoring. The other component, the UAMS Information Dissemination Layer (UIDL), will handle coordinating communications necessary for airspace control. The UAMS Planner will implement AI reasoning procedures for Airspace plan generation, monitoring and repair. The UIDL will implement an agent-based framework for intelligent information dissemination based on the DAIDS effort. The UIDL will have the following functions: . Dynamic team formation . Dissemination policy generation. . Communications adaptation. UAMS will use the most advanced AI techniques available in generating, monitoring, and repairing UAV airspace management plans. The quality of the generated plans and the ability to rapidly detect and fix conflicts will allow the highest degree of flexibility in UAV operations possible. It will use a software agent-based intelligent information exchange framework to minimize the amount of bandwidth required for airspace coordination, and will be adaptable to support centralized, distributed, or hybrid control protocols

Title:SMA Active Rotor Trim Tab
Abstract:Mid‚ proposes to build an on-blade active trim tab using Shape Memory Alloys. SMAs are active materials that undergo a phase change from martensitic to austenitic form when heated. The materials can be trained to a specific shape in the austenitic phase. When heated, the material will recover the trained shape. Since the modulus in the austenitic phase is relatively high, the force exerted is large. The specific energy in the device is very high, and the form factor is small, since the actuator consists in essence of a wire bundle. The proposed actuator is a self-locking device so that no power is required to hold a trim tab set point, and the failure modes are benign. A fixed-frame control system is used to set tab position, so that the system requires no fixed/rotating frame data transfer.

Title:Dismounted Small Unmanned Air Vehicle (SUAV) Associate
Abstract:GUAVA will provide a PDA-based associate system for the dismounted soldier operating a small UAV. This system will augment the soldier in the field to realize a force multiplier benefit through assistance with effective UAV employment. As an associate system for the dismounted soldier, GUAVA will be cognizant of the operator's plans, goals, and situation. In particular, GUAVA will interpret a set of succinct commands such as "cover me" or "search along my route" and translate them into commands for the UAV. GUAVA will also be aware of what kind of tactical data is of the greatest interest to the soldier and will alert him appropriately when it is received. GUAVA will include a suite of agents based on ATL's Autonomy software. These agents will increase the autonomy level of the UAV/PDA GUAVA pair by providing system monitoring, analysis, diagnosis, capability assessment, and mission impact capability. GUAVA will use the Distributed Agent-Based Information Dissemination System (DAIDS) developed by ISX and ATL for AATD. GUAVA will use dissemination policies to determine the priority of tactical data, status messages, and control commands for exchange using the tactical data link.

Title:Inter-Turbine Burners for Improved Part Power Performance of Turboshaft Engines.
Abstract:he use of an inter-turbine burner for improving the part power performance of small turboshaft engines in proposed. An inter-turbine burner is a second combustor placed between the gas generator exit and the power turbine to "reheat" the engine gas stream before it enters the power turbine. The inter-turbine burner is used to increase engine power at the maximum power setting permitting the core engine to be run closer to its design condition at part power settings. Cycle analysis shows significant improvement in engine power with an accompanying increase in specific fuel consumption at the full power condition. The part power specific fuel consumption improves by significant at power levels below half of the maximum power. This improve specific fuel consumption at part power settings will reduce fuel consumption during the cruise/loiter segments of the UAV mission. Thus there is a net benefit to time-on-station, provided that the cruise/loiter segment is long compared to the take-off and climb segments. The increased specific thrust of the turboshaft engine with an inter-turbine burner results in a lighter engine for the same maximum power.

Title:Merging Sensor and Stored Terrain Database Data for Rotorcraft Poor Visibility Weather Operations
Abstract:A joint venture team consisting of three small businesses, Monterey Technologies, Inc. (MTI), Nav3D, and AIREYES, will perform this work. The ultimate goal of the team is to produce a functional, Integrated Multi-sensor Synthetic Imagery System (IMSIS) that merges information from radar, IR, and other sensors and a terrain data base to produce a synthetic image of the scene on a panel-mounted display. The inclusion of real-time radar and other sensor information in the IMSIS display compensates for the inability of a Synthetic Vision Systems (SVS) to display detailed, current obstacle information relevant to Army helicopter operations, e.g., trees and wires, recent battle debris. The Phase I work will produce one or more animated displays illustrating the IMSIS display design to demonstrate the capability to present, and the effectiveness of, imagery from merged sensor and terrain database information. The design goal is a rotorcraft display to allow the pilot to easily interpret and avoid flight path obstacles while maintaining overall awareness of the aircraft and the environment in currently unflyable visibility conditions. Avoiding SVS perceptual capture is another design goal. The team has already produced displays that combine fuse sensor information and synthetic terrain imagery for fixed wing operations.

Title:Fatigue crack detection using built-in Sensor Cluster Network
Abstract:The performance and behavior characteristics of nearly all in-service structures can be affected by degradation resulting from sustained use as well as from exposure to severe environmental conditions. Condition awareness of structures in (near) real-time is therefore an important factor that can limit or extend their service life. Acellent Technologies proposes to develop an innovative one-of-a-kind system that will combine Acellent's current single-element SMART Layer actuator/sensor network together with multi-element phased arrays to produce a Sensor Cluster Network that has been geometrically optimized to (a) Quantitatively assess structural damage such as cracks due to fatigue, (b) Identify damage in inaccessible areas of rotorcraft structures, (c) Characterize damage growth, and (d) Provide an image of the damage size and orientation. The basis for the development will be Acellent's SMART Layer technology that utilizes a network of distributed transducers that are integrated with the structure itself and serve as sources for acousto-ultrasonic structural data. The technology in its current form can be used to identify damage location and extent and the utilization of geometrically optimized sensor/actuator clusters can further enhance the use of the methodology and improve the resolution of damage detection such that small linear fatigue cracks can be easily detected.

Abstract:An innovative approach to self-healing composite fabrication is proposed by Global Technology Connection along with its project team from Georgia Tech, Texas A & M and industrial partners Bell Helicopters, Boeing Rocketdyne, Goodyear. The approach addresses the short-comings of current approaches namely low strength of the healed material especially following any impact damage and fatigue-induced damage. Achieving this objective will enhance Army readiness, increase safety, and reduce maintenance labor, time, and cost. In Phase I, concept for developing a new composite with self-healing capability will be demonstrated in concert with US Army Aviation. The feasibility of such an approach will be demonstrated with suitable coupon and sub-element test specimens. The transition plan for the prototype development along with scale up issues will be fully addressed. In phase II, more extensive testing of sub-element and component testing representative of actual rotorcraft part/environment will be undertaken by partnering with US Army rotorcraft prime contractor. This testing would validate the methodology, developed in the previous phase. The demonstrated technology will meet Rotary Wing Vehicle Technology Development Approach (RWV TDA) Phase 3 Technology Objectives for improved structural efficiency and affordability

Title:Self-Healing Composite Structures
Abstract:The main thrust of the proposed research is to develop a novel fiber coating system which builds self-healing attributes into fiber reinforced composites. The new fiber coating is a layered composite of piezoelectric and solid electrolyte constituents. The piezoelectric layer generates electric potential in response to fiber stress rise in damaged areas. This potential drives electrochemical processes in the context of the solid electrolyte layer, which transport structural substance towards highly stressed (damaged) areas where they would be electrodeposited to render self-healing effects. The structural substance rendering self-healing effects comprises metallic nanoparticles dispersed within the solid electrolyte layer. The system essentially converts the mechanical energy input of service environment (which concentrates in damaged areas) to electrical energy for driving the self-healing process. Self-healing is an intrinsic attribute of this system, with piezoelectricity providing for both sensing and actuation effects, and concentration of stresses in damaged areas yielding an inherent control of the self-healing phenomenon. We have conducted fundamental theoretical studies to validate the following key hypotheses of our approach: (1) piezoelectricity can generate the potential needed to drive electrolysis phenomena within solid electrolytes; (2) conversion of mechanical to electrical energy by piezoelectric effect can generate the charge needed to transfer structural substance at viable rates; and (3) increased concentration of metal nanoparticles within polymer-based coatings can make meaningful contributions to the mechanical performance of fibers, thereby strengthening damaged areas of fiber composites. Our approach focuses on enhancing the mechanical performance of fibers (in lieu of the matrix) in damaged areas, recognizing the critical contributions of fibers to mechanical performance of composites. The proposed Phase I (and Phase I Option) research will establish an analytical framework for design of self-healing composites, and will experimentally validate the fundamental principles of the approach through establishment of processing methodologies, and design, fabrication and experimental verification of basic self-healing composites embodying our principles. A multi-disciplinary team of top industrial and university researchers with specialties in the fields of composites, piezoelectricity and solid electrolytes has been assembled to conduct the proposed research.

Title:SMART SNUBBER/DAMPER FOR FIVE FOLD INCREASE IN DAMPING OF BEARINGLESS MAIN ROTOR BLADES
Abstract:Snubber/damper damping performance is severely limited by component size and load constraints yielding insufficient RLM damping. Solutions using existing technology lead to excessive snubber damper size and weight to accommodate all operating conditions. Also, current snubber/damper designs are not sufficiently reliable and have limited life. High damping is required for stabilizing ground and air-resonance (rotating frequency of interest typically 0.3-0.7P). However, simply increasing the damping of snubber/dampers designs will also increases the 1P lead-lag associated loads and reduce related component lives One solution to the above problem would be to design a ­.smart­" snubber-damper that takes advantage of the superimposed 1P motions by producing damping forces that oppose Ÿ‡lag motions but produce zero or low force when the net damper loads are not favorable for suppressing Ÿ‡lag motions. This is not possible using conventional passive dampers because passive elements like relief valves, orifices, produce forces that oppose the net velocity even if the resulting force excites the regressive lag mode! The new active concept arises from the recognition that the net damper force, i.e. from the combined Ÿ‡lag and 1P motions, often produces forces that can be advantageously used to suppress Ÿ‡lag response, thus converting a chronic difficulty in damper technology, unwanted 1P motions, into a benefit. The proposed concept relies upon two actions: 1) Minimizing the net damper force when it is in the same direction as the Ÿ‡lag velocity. This avoids adding energy to the Ÿ‡lag mode. This would be done by selectively opening a controlled valve to equalize the pressure in the damper chambers thus not allowing pressures to build. 2) Maximizing the net damper force when it opposes the Ÿ‡lag velocity. This would extract energy from the Ÿ‡lag mode. This would be done by selectively closing a controlled valve to maximize the damper load.

The MRFE snubber/damper will increase flexbeam life, extend the stability envelope for air resonance, and extend damper life. The MRFE snubber/damper system will augment damping inflight only when required as commanded by the controller. To enable retro-fit to existing rotor systems, the electrical power required to operate the actuator will be drawn from the DC power bus supplying the main rotor de-icing system.

Title:An Affordable Health and Usage Monitoring System (HUMS) for UAVs
Abstract:Impact Technologies, in collaboration with Lord Corporation and the Georgia Institute of Technology, propose to develop an affordable/miniaturized health and usage monitoring system (HUMS) for unmanned aerial vehicles (UAVs). Based upon the unique requirements of UAVs, an innovative hardware/software solution will be developed and demonstrated that includes embedding advanced vehicle health management algorithms for anomaly detection, fault classification and prediction into a low-cost, aerospace-certified digital signal processing (DSP) based hardware platform. All critical parameters related to UAV performance and mechanical health will be monitored including aero-thermal flight parameters, propulsion system information, structural/vibrations and vehicle subsystem performance data to address condition-based maintenance activities that are required to ensure UAV mission success. Key UAV subsystems including the gas turbine engine, drive train (shaft/clutch), fan, louvers, actuators (fight control) and avionics will be monitored by the proposed system. The proposed UAV-HUMS will continuously assess and track the health of all critical UAV subsystems using a combination of anomaly detection and diagnostic reasoning software that can communicate the health status of the vehicle through a low-bandwidth air-to-ground link. The anomaly detection software will implement proven signal processing and automatic signal feature extraction techniques that are capable of identifying abnormal system behavior and reporting it to the diagnostic reasoning software. The diagnostic reasoning modules will utilize a combination of fuzzy reasoning and robust fault classifiers such as neural networks and support vector machines to obtain the fault diagnosis of the UAV. The development and integration of advanced diagnostic and prognostic algorithms into a real-time health monitoring system is expected to improve UAV mission success rates and positively impact total ownership costs. The proposed Phase I development includes a hardware/software demonstration of the next generation UAV-HUMS including embedded anomaly detection and diagnostic reasoning algorithms, DSP hardware specification and an on-board/off-board design trade study. This work will leverage Impact's existing expertise in air vehicle prognostic health management systems, Lord's expertise in flight-qualified electronics hardware and Georgia Tech's helicopter UAV test bed.

Title:Composite Fastener Development
Abstract:Composite materials offer excellent specific strength and specific stiffness advantages over metals for flat panels such as aircraft control surfaces and aerostructure that are stressed in two dimensions only. Fastener materials, however, typically are stressed in three dimensions, so isotropic metal fasteners are universally better structurally than composite fasteners. Unfortunately, metal fasteners are incompatible with composite aerostructure in terms of conductivity, hardness, strength, radar signature, and density. TRI/Austin proposes to incorporate state-of-the-art composite fastener technology into addressing the needs of the Army's Comanche program to capitalize on the compatibility of composite fasteners with composite aerostructure while ensuring the lack of high isotropic material strength is addressed through novel design. TRI/Austin has expertise in the areas of testing, materials research and development, tooling, and manufacturing to develop fully functional composite fasteners.

(TSI) proposes a revolutionary combination of material, process and configuration innovations enabling a new generation of composite fasteners having the tensile and shear capability today's UNJF-3A titanium fasteners yet meeting critical LO, clamping force, durability and weight reduction needs specific to Army needs. TSI fasteners can be made using composite engineered materials such as reinforced polymer matrix composites (PMC) or as ceramic matrix (CMC) or metal matrix (MMC) composite. TSI's hybrid materials also allow fastener design as functionally graded polymer / metal and metal / ceramic composites (PMMC and MCMCT). These engineered materials use similar low cost forming and processing technologies. In design discussions with aircraft and vehicle team integrators, Army systems such as the RAH-66 Comanche and family of FCS land & aero vehicles require fasteners allowing connection of composite parts to other structure elements. TSI's innovative approach(s) will reduce un-wanted effects with metallic fasteners including galvanic corrosion, damage to composite materials during assembly (excessive clamping forces) and during dis-assembly and fastener loosing under high vibration and cyclic usage. Finally, by design TSI's fasteners can reduce parasitic weight by replacing heavier metallics with lightweight composites yielding structural weight reduction while providing enhance survivability from radar detection.

Title:Analysis, Design & Test of Low Reynolds Number Rotors and Propellers
Abstract:The successful development of unmanned air vehicles (UAVs) has allowed aeronautical design to proceed without the limitations that are inherent to manned vehicles. As a result, extremely small UAVs are currently under development, including both aircraft and rotorcraft. Also, UAVs are being designed to work at extremely high altitudes, or in extraterrestrial environments with extremely thin atmospheres, such as Mars. UAVs that are small in size or operate in extremely low-density environments experience much lower Reynolds numbers than do conventional aircraft. Since aeronautical CFD has been mostly concentrated on high-Reynolds-number flows, the aerodynamics and computational simulation at low Reynolds numbers are poorly understood. These flows may exhibit combinations of laminar, transitioning, and fully turbulent flows (and may include compressibility effects) that present challenges to both experimental and computational disciplines. A practical analysis and design tool is proposed for three-dimensional low-Reynolds-number flows. The approach is based on vorticity confinement, a CFD approach that allows viscous effects to be modeled with relatively coarse grids and low computational requirements. Vorticity confinement allows vortical structures, such as separating boundary layers, to persist and be convected in a physically consistent manner. This effort extends the vorticity confinement approach to the low-Reynolds-number flow regime.

Title:High Strength, Affordable Helicopter Gears
Abstract:The Army's Rotorcraft Force Modernization Fleet requires a substantial increase in main gearbox power density, with minimal impact on the gearbox interface. Instead of increasing gearbox size and transmission weight, this project seeks to accommodate the higher power density requirements through designed material processing techniques, integrating several state-of-the-art manufacturing processes to specifically improve the gear material contact and bending fatigue strengths. In Phase I, a novel heat treating method called "Intensive Quenching", as well as superfinishing will be investigated to determine the feasibility of improving the bending fatigue life of the Pyrowear 53 steel by at least 25% over conventional processing.

Title:High Strength, Affordable Helicopter Gears
Abstract:The Army's SBIR Phase I solicitation seeks to demonstrate the potential for improved bending and contact fatigue strength of gear alloys for increasing the power density of main helicopter gearboxes. QuesTek Innovations proposes to utilize advances in gear steel technology and surface treatment processes to address these objectives. It is possible to improve gear performance through both advanced materials and surface treatments. QuesTek will evaluate laser shock peening as an improvement to traditional shot peening to increase bending and contact fatigue strength for test coupons of conventional Pyrowear 53. Additionally, advanced gear steel test coupons of GearMetO C61 and GearMetO C69 will be evaluated as superior alternatives to Pyrowear 53. Material improvement and an optimal surface treatment will allow for an increase in fatigue strength and a subsequent increase in gearbox power density. QuesTek will team with Bell Helicopter to evaluate the potential benefits of incorporating laser peening of Pyrowear 53 and to additionally evaluate GearMet C61 and C69 for both military and commercial helicopter gear systems. Results of Phase I coupon tests will be used to establish the feasibility that Phase II gearbox testing has a significant probability of achieving a 25% improvement in bending and contact fatigue.

Title:LED-based Inertial Reference System for Aviator Helmets
Abstract:Intelligent Automation, Inc. (IAI) propose to develop a robust, high-speed, high-accuracy helmet-tracking system for use in the Comanche helicopter. Current systems have numerous problems, such as requiring recalibration whenever the cockpit environment changes, time-consuming mapping of the cockpit, and the inability to process data in real-time. Our proposed system uses a number of photosensitive detectors (PSDs) to look at a known pattern of dots on the helmet to determine position and orientation of the helmet in all six degrees of freedom. Using an algorithm we have developed that is capable of calculating absolute position from the image of the dots, we can build a robust system with accuracy and refresh rates that are over two orders of magnitude better than the requirements. We have extended the algorithm so that any given PSD does not have to see all of the LEDs. This redundancy enhances the robustness and accuracy of the system. During Phase I, we will demonstrate the feasibility of using PSDs and LEDs for helmet tracking through high-level design, simulation, and experiments. As a Phase I Option, we propose to conduct initial testing in a cockpit using an actual helmet to verify system performance.

Title:Cockpit Helmet Tracking System Using Miniature Inertial Reference Sensors
Abstract:InterSense has previously developed ultra-miniature (0.6 in.3) MEMS-based InertiaCubeT inertial measurement units for human motion tracking. In this SBIR, we will further miniaturize and apply them to cockpit helmet-tracking by developing integration and Kalman filtering algorithms for differential inertial tracking between helmet-mounted and aircraft-mounted inertial sensors, and novel optical drift correction techniques. By fusing low-rate inside-out and outside-in optical measurements with high-rate inertial data, we will achieve sub-millimeter position accuracy and sub-milliradian angular accuracy, low-latency and high robustness using small and inexpensive sensors. During Phase 1 we will produce a prototype tracking system suitable for flight testing and explore four innovative techniques to produce a revolutionary advance in cockpit helmet tracking. We will prove the differential inertial tracking approach with a working prototype, evaluate the relative benefits and trade-offs of inside-outside-in v. outside-in optical aiding approaches, define powerful estimation-theoretic auto-calibration and auto-boresight procedures to achieve quick and accurate cockpit installation and pre-flight alignment, explore using direct high-bandwidth feedback from the inertial sensors to image-shifting optics to cancel display vibration, identify suitable optical wavelengths for covert operation, and develop a plan to miniaturize and harden the inertial and vision sensors in Phase 2.

Title:Small Multi-decade Communications and Electronic Warfare (EW) Antenna
Abstract:The RF bandwidth from 20 MHz to 2000 MHz is of particular interest to the US Army as it encompasses various communications, sensors, and electronic countermeasure systems. Developing a small antenna with 100:1 bandwidth would resolve many problems associated with multiple individual antennas including co-site interference, blockage, and overall real estate availability. The proposed baseline antenna design will provide improvement in size and performance well beyond the stated goals of this solicitation. The baseline approach will provide a lightweight passive antenna that is broadband and non-tunable and will cover frequencies from approximately 20 MHz to 2000 MHz. Reactive tuning techniques will significantly reduce the size of the antenna and innovative antenna apertures will minimize the interaction with vehicle mounts to improve low angle performance. Overall, FIRST RF has an in-depth understanding of the problem and its application. The proposed approach will directly meet the intended requirements of the SBIR program, as well, as being directly applicable to solving current problems in communications and EW antennas. We intend to model and prototype several antenna candidates as part of Phase I, thereby, enabling US Army and contractors to perform evaluation on early units.

Title:Scalable and Robust Blockage Mitigation Techniques for On-the-Move Satellite Communications
Abstract:Satellite communications (SATCOM) are integral part of both military and civilian communication infrastructures. Applications are being developed that require satellite communications support for mobile satellite terminals. However, both urban and rural terrain present many obstacles that block satellite signals and interrupt voice, video and data transmissions for moving military tactical vehicles and civilian vehicles. To address this real barrier to effective communication, military and civilian satellite terminals need scalable and robust mechanisms to ensure that voice, video and data communications are received correctly and in their entirety despite interruptions during transmission due to blockage caused by obstacles. This needs to be accomplished without using excessive amounts of limited SATCOM bandwidth. Leveraging extensive experience in wireless network technology, Architecture Technology Corp (ATC) will develop a system that provides blockage mitigation techniques for networks of on-the-move satellite terminals. The system will maintain the QoS requirements of multimedia flows despite satellite signal blockages.

Title:Blockage Mitigation Techniques for On-the-Move Satellite Communications
Abstract:The primary objective of Phase 1 of the proposed project is to design a ground-based protocol to provide reliable and efficient communication services by overcoming the problems associated with fading and blockage by terrain obstacles. The protocol will address both voice and data communication. In particular, the protocol must overcome the low and variable quality of service offered on mobile satellite links and provide reliable and timely indicators of link availability and quality to the users. Seamless communication service is desired as the users move through varied terrain. The protocol will use techniques such as data compression, forward error correction, acknowledgement and retransmission protocol, instantaneous rerouting, caching, and proxies to achieve this goal.

Title:Extensible Markup Language (XML) Compression Tool
Abstract:XML is becoming the dominant means of universally communicating data designed to be processed by machines in networks, much the same way as HTML has become the dominant means of communicating data designed to be processed by human beings. However, like HTML, the human-readable source format of XML leads to large files with many redundancies. Therefore, although universal, XML documents are not the most efficient way to transmit and store data. In the field, such efficient transmission and storage is vital to the data-gathering effectiveness of a unit. Because the XML format is universal, it cannot be abandoned, thus making XML compression necessary. This project consists of the following objectives designed to achieve efficient XML compression. Firstly, design and develop a novel and efficient XML compressor (and decoder) based on context analysis and machine learning. Secondly, design and develop a preliminary codec using this compressor/decoder that will in addition compress any still or video imagery that might be included in the XML data stream. The anticipated result of this Phase I research is (1) the design of a superior intelligence-based, adaptive XML compression method and associated algorithms (2) the development of a preliminary XML compression tool based on the algorithms designed. The feasibility of this nascent compressor will be demonstrated and performance will be scientifically extrapolated in order predict the efficiency of the compressor to be developed in Phase II.

Title:Applying Gaming Technology to Military Visualization - Games where You Only Live Once!
Abstract:Applied Visions, Inc.(AVI) proposes to design a flexible, extensible application program inter-face (API) to commercial game engines that will provide Military Commanders, in a collaborative environment, with high-quality 3D visualization of the outputs of current and emerging C2 applications. Our approach is to attack the problem from two aspects: a) to harness the power of the gaming engine without invoking features, which while vital to success in game products, result in false or misleading information in a C2 environment, and b) to extend the game engines abilities to in-clude more accurate physical modeling, including elements of the non-visual spectrum (e.g. IR & RF) which are an integral part of the FCS (Future Combat Systems) architecture and will add vital, mission-related information to the Commander's visualizations Combining AVI's extensive experience in 3D visualization and military simulation with the Gaming Engine expertise of our consultant, Dr. David Sturman, our Phase I effort will be de-voted to defining the key requirements of the systems architecture, designing the API and imple-menting an early prototype to demonstrate core features of the full system. Our Phase II effort will refine the architecture, upgrade the prototype and integrate it with emerging Future Combat Systems (FCS) C2 applications.

Title:Military 3-D Visualization Utilizing Gaming Technology
Abstract:In support of Future Combat Systems (FCS), the U.S. Army is seeking to develop a solution that will allow the state-of-the-art in gaming technology to be integrated seamlessly into a planned military Command and control (C2) facility. This initiative will support C2 applications such as the Commander's support Environment, Combined Arms Planning and Execution Systems and the DaVinci Toolkit. In an effort to present a visual representation of the current simulation state of the C2 applications, a standard application programming interface (API) to the visualization component is necessary. However, existing applications provide data in various formats each unique to the application. CG2 proposes to develop the "Constructive Game Engine Abstraction Library" (conGEAL) API. This standardized API will work with C2 data models, XML Schema and DTD, as well as support NIMA maps and imagery and take live feeds from FCS military planning tools, in a networked environment. Work performed during this Phase I effort will include the investigation of existing game engine technologies and explore the integration of the game engines into the C2 environment via the conGEAL API. All aspects of the proposed conGEAL API will be investigated and recommendations made to ensure a successful completion of a prototype API in Phase II.

Title:Ultrafast Charging of Smart Lithium Ion Rechargeable Battery Hybrid Power Sources
Abstract:To meet ultrafast charging requirements for the LI7 land warrior battery, we propose building a large format, high power lithium ion battery using the high rate technology that already exists and is available from Lithium Technology Corporation. This battery will not only discharge quickly to provide the rapid recharge of the LI7 units, but will itself be capable of recharging quickly from another power supply. Initially, we will quantify energy storage and heat generation for a variety of charging and discharging protocols at the single cell level - both 9Ah and 27Ah - all within 30 minute duration. From these tests, we will select protocols that offer the highest specific energy actually stored in the LI7 units in 30 minutes and test them using full scale 4S large batteries and 4S4P arrays of 18650s. Last, we will recommend power electronics to condition the voltage and current output based on the outcome of the full battery tests. Also, a Phase I Option is recommended to scale-up the best effort results from Phase I. A portion of this work will be subcontracted to PennState Future Truck group. Lithium Technology Corporation will perform over 67% of this work in its Plymouth Meeting, PA facility.

Title:Lithium-Air Technology
Abstract:This Small Business Innovation Research Phase I project will advance the lithium air battery with improved rate of discharge, capacity, and water repulsion. Specifically the project advances lithium air batteries by focusing on increased oxygen diffusion in the porous carbon electrode by the use of oxygen transport molecules in the electrolyte. Typical problems of metal air batteries are low oxygen diffusion rates and water contamination. By enhancing the electrolyte with oxygen transport molecules and using a non-aqueous proprietary thin film composite polymer electrolyte, the battery system will greatly improve in both of these aspects. The oxygen transport molecules will increase the amount of dissolved oxygen carried by the electrolyte in the porous air cathode. This will increase the rate of discharge and the capacity by distributing the oxygen throughout the pores of the cathode. We propose to increase the oxygen diffusion rate of the cathode structure by investigating different oxygen transport molecules in combination with several electrolyte compositions. Yardney's experience and technologies in the metal-air power sources will be adopted in the design of the new advanced Li-Air battery. Advantages of the proposed lithium air battery include a high energy density, safe design, environmentally friendly components, and increased oxygen diffusion.

Title:Agent-based Commanders Portal Technology
Abstract:The Agent-based Commander's Portal Technology (CPT) concept is to provide an environment for the operational commander or action officer to manage their activities and mission information while maintaining a shared situational understanding. This is achieved by building application components on top of an agent-based workspace technology actively under development by Cougaar Software. This technology is based on the Cognitive Agent Architecture (Cougaar), the result of a $100M DARPA program. The core concept of CPT is to have panel agents behind each application component, and another agent responsible for the overall task-oriented application. These application agents coordinate over shared workflows and shared representations of the relevant situation. Other agents are responsible for interfacing with external data sources and collaborating with other agent-based interface environments. Together, all the agent environments share and maintain a common operational picture, even though each agent community supporting an operator's interface environment is only responsible for pieces of the larger situation. An Agent-based Commander's Portal would provide the commander or operator with dynamic information management, task-centric information display, intelligent automation, workflow-based collaboration and innovative agent-based application components.

Title:Using Cognitive Systems in Generation of Course of Action
Abstract:This proposal will increase the efficiency of knowledge processing and decision making by the Objective Force by providing the warfighter with the software for supporting the process of developing the Course of Action (COA). The processing time will be reduced by more than an order of magnitude and the quality of the results will satisfy the highest standards of the quality achievable in automated decision making processes. Automated processing of data referenced in multiple documents is required for the Intelligence Preparation of the Battlefield process. The decision aids based upon COA are required for mission planning, activities simulation, and plan execution in the battlefield. COA combines geographic data with detailed descriptions that should be processed automatically. As a result of this research new technologies will be developed reducing required computations resources and efficiently utilizing knowledge of natural and man-made features. COA-based decision aids should be developed for multiple DOD elements with the goal to improve their integration and consistency of functioning. We employ new tools that allow for supporting nested and visualization tools helping to integrate descriptive, topographical and pictorial elevation information into a multiresolutional knowledge and data representation, thus forming a knowledge repository.

Title:Linguistic Geometry Intelligent Nodes for COA Generation and Analysis
Abstract:We propose to develop and demonstrate a new approach to rapidly conceptualize and prioritize information vital to Objective Warrior (OW). The approach is based on Linguistic Geometry (LG), a mathematical theory for strategic superiority discovery. The most significant advantages of the LG approach are modeling of the intelligent enemy and extraordinarily fast automatic generation of best strategies, tactics and COA for all the sides of a conflict. We will also develop LG based semantics for BML as well as LG based architecture for intelligent nodes (IN) to generate and analyze COA options. Utilizing these semantics and architecture, we will develop operational specs for a software prototype of LG-CHALLENGER representing the COA generating and analyzing engine of the IN capable to understand and assign semantics to BML sentences. In addition, utilizing our proprietary software LG-FRAMEWORK as well as our existing prototypes for IAD (integrated Air defenses), SEAD missions, and effect-based operations (EBO), we will develop experiments illustrating feasibility of LG-CHALLENGER. With LG-CHALLENGER, an OW will be able, using convenient LG templates, to map the entire operational battlespaces into LG hypergames providing intuitively clear common operational picture (COP). The OW will employ LG-CHALLENGER to obtain COA options that will allow the OW to plan and execute future warfare missions including IAD, EBO, Joint, asymmetric, and humanitarian relief operations. The LG-CHALLENGER engine will communicate with the information carrying cells via BML, and with the OW via BML and human-centric GUI.

Title:Near-Real Time Tactical Automated Machine Translation Technology(N-TAMTT)
Abstract:Recent DARPA-sponsored MT evaluations showed that phrase-based statistical MT systems derived through automatic training on very large corpora achieve the highest translation quality for both generalized and specialized texts. Intuitively, syntax, morphology, and semantics should help; however, rule-based systems that incorporate such knowledge are not yet able to beat the best statistical systems. We propose the following plan for incorporating richer linguistic knowledge into the translation process: . Start from a good baseline: the best A2E machine translation system in the world (as evaluated by NIST). . Devise experiments to determine major sources of error in the system (E.g.: verb agreement; morphological errors; contextual errors) . Assess the impact that solving these problems may have on translation quality. This is done by measuring the increase in BLEU score when a problem is fixed. Assess how our current system should be enriched to deal with each of these problems. . Rank-list the problems in order of impact on translation quality and feasibility of addressing them using richer linguistic knowledge (morphology, syntax, semantics, context). . Devise solutions for solving these problems in turn and incorporate the solutions into an end-to-end system

Title:Near-Real Time Arabic/English Machine Translation by Integrated Statistical and Linguistic Learning Methods
Abstract:StreamSage proposes an approach to the automatic translation of Arabic and Arabic dialect texts to and from English that significantly extends the state-of-the-art in regards to the integration of statistical and traditional machine translation techniques. This research will greatly increase translation accuracy while decreasing the need for domain-specific training. The proposed near real time translation system will use automatically induced transfer rules between English and Arabic syntactic structures that have been statistically trained on a feature set that is of unprecedented sophistication. This feature set will be automatically generated through the use of tools that have not before been applied to Arabic machine translation, such as language-wide noun and verb sense disambiguation, a TAG-Based Stochastic Parser, and a hierarchical representation of Arabic dialect morphology, lexical features, and syntactic structures. Additional innovations include the application of state-of-the-art Arabic morphological analysis throughout the translation process, from word sense disambiguation to transfer rule induction to generation, and the automatic induction of syntactic-structure to target language generation rules. This research will make use of past work in machine tranlation, Arabic parsing, Arabic dialect analysis, and word sense disambiguation by StreamSage, Columbia University, and CoGenTex.

Title:An Adaptive and Distributed Approach to Developing and Maintaining an Integrated Search and Discovery Portal
Abstract:We propose an innovative approach to supporting the Army's Homeland Security (HLS) mission that turns the diversity of perspectives that exist amongst largely autonomous HLS communities in DoD and non-DoD organizations into an exploitable strength. In particular, we propose to develop an approach to the development and maintenance of a search and discovery portal that exploits an eclectic set of techniques in order to achieve functional and semantic interoperability amongst these communities without forcing participants to conform to the type of oppressive monolithic semantic schema that has led to the demise of so many corporate knowledge management efforts over the past decade. Rather, the proposed system, Vista, will employ an adaptive distributed paradigm where individuals and groups can manage their local information in a manner that fits their respective workflow patterns and Vista will exploit this diversity in a machine learning based bootstrapping approach to meaning negotiation. The resulting system will be capable of delivering personalized and context-aware information access and awareness in support of the Army's information superiority needs. Phase I research and the development and evaluation of a limited prototype will provide a solid foundation for the complete implementation of Vista in Phase II and its commercialization.

Title:Absolute Distance Hemispherical Rangefinder
Abstract:Physical Optics Corporation (POC) proposes to develop a new absolute distance hemispherical rangefinder (ADHER) for 3D rendering of large rooms and cavities for combat operations of Objective Force Warriors. The proposed ADHER is a nonscanning, compact device for stealthy robotic platforms. The ADHER design is based on an innovative optical fish-eye lens with telecentric arrangement, a smart pixel array, and unique software implementing the Chinese Remainder Theorem for distance retrieval and the DaVinci visualization infrastructure. The ADHER optical system to be developed in Phase I is extremely compact -- 30 mm in length and 10 mm in diameter. ADHER will enable instant 3D hemispheric rendering of objects of interest with several millimeters distance resolution and one degree scene resolution. It will be mass producible, reliable, low in cost, and specifically suited to future urban combat and antiterrorist operations. In Phase I, POC will develop a complete computer simulation for system modeling and a preliminary ADHER model prototype to demonstrate the feasibility of our approach. In Phase II an engineering prototype ADHER will be developed and integrated with a stealthy robotic platform and advanced 3D rendering software.

Abstract:Rapidly evolving technology and network connectivity are enabling innovative command and control systems, concepts, and strategies, yet no accepted measures exist for assessing the effectiveness of those innovations. Because effective C2 outcomes are difficult to define, and the contribution of individual behaviors to those outcomes is rarely clear, a model or framework is needed to guide measure development.

This tool will provide users with the capability to: (1) develop a model of the C4ISR architecture for the C2 unit or component being assessed (e.g., a command post or Tactical Operations Center); (2) use the model output to identify the most important factors to be measured; and (3) generate examples of data collection strategies for obtaining empirical data on the desired measures. The final product (in Phase II) will be a C2-MATE tool that identifies appropriate measures based on an architecture model and draws on a library of operational measures and data collection methods and instruments to make recommendations for C2 assessment. Although the initial focus will be on the Army C2 TOC, the tool will be designed to support C2 measurement in a variety of environments.

Title:Advanced Azimuth Estimation Techniques
Abstract:The short radar sensor baseline and low RF frequencies required to penetrate foliage on typical UHF GMTI radars cause the azimuth extent of the main beam to be quite large, producing large azimuth error ellipses that limit the target location accuracies that these systems can achieve. Since accurate target location in both the range and azimuth dimensions is desired to support precision location, targeting, and tracking of enemy targets utilizing camouflage and concealment tactics, future UHF GMTI systems need to devise innovative ways to limit these large azimuth errors. This Phase I SBIR will investigate, analyze, and present various innovative approaches to achieving improved azimuth angle estimation from UHF GMTI radar systems onboard rotorcraft air vehicles by using a combination of monostatic, bistatic, and multilateration techniques. Computer simulations will be used to evaluate the performance of the various azimuth estimation techniques, which will employ adaptive and superresolution methods. The effectiveness of monostatic, bistatic, and multilateration techniques will be compared, and the most promising techniques will be identified. Radar measurements of the moving targets including range, Doppler, and angle of arrival will be exploited to improve the azimuth angle estimates for these UHF GMTI radars.

Title:Video-Moving Target Indicator (MTI) Trackers for Multiple Targets
Abstract:Motion imagery comprises an information-rich data source complementary to radar and other sensors. Video cameras can operate in various frequency bands, including infrared (IR) and visible spectrum electro-optical (EO), and provide multi-dimensional measurements across both spatial and temporal domains. Except for simple functions, however, human operators are required to scan the area of regard, designate objects of interest, and track single targets. The objective of this effort is to automate the use of video/imagery for the detection and tracking of multiple movers to provide reduced operator workload, enhanced situational awareness, and support follow-on intelligence and targeting. ALPHATECH proposes to modify and extend our multiple target tracking architecture, currently being developed for the DARPA Video Verification of Identity (VIVID) program, to conform to Army CECOM objectives and to rapidly achieve desired performance levels. We will focus on specific needs of the Army, such as the accurate absolute location of targets on a topographic coordinate frame, and will develop technology that enables detection and tracking of move-stop-move objects, exploiting the wealth of information provided by video. We will assemble a custom testbed from existing components to demonstrate tracking performance in scenarios agreed upon by the Army CECOM technical monitor.

Title:A Novel Motion Tracking Indicator Algorithm for Multiple Target Tracking
Abstract:This SBIR Phase 1 project investigates algorithms and methodologies necessary to extract multiple moving objects/targets out of video/imagery data, establish individual tracks for each and maintain those tracks over multiple image frames Genex Technologies, Inc. proposes in this SBIR effort to develop and test the feasibility of a novel Motion Tracking Indicator (MTI) algorithm that reliably detects, extracts, and tracks the location and history of the movement of multiple targets in real-time within any imagery data (i.e. Visible, near-infra-red, infra-red, image intensified (I2), UHF ground-based radar, or any imagery yielding movement of multiple targets within a stationary or moving background). We propose a unique design for a MTI algorithm that provides a unique approach to making detecting and subsequent target tracking both reliable in terms of False Acceptance Rate (FAR) and False Rejection Rate (FRR). Genex will use a variety of mathematical models in a unique design that considers the "state" of the object to improve tracking reliability.

Title:Knowledge Engineering Environment for Army Intelligence Analysis and Interpretation
Abstract:Traditional methods for constructing knowledge-intensive systems have relied heavily on intervention from artificial intelligence specialists. The first step in this intervention is typically either: extensive human-directed interviews of subject-matter experts so that the knowledge can then be laboriously hand-encoded; or the training of SMEs in some highly-restricted intermediate representation. Such systems have been costly to produce, and have typically failed to model expert knowledge to any degree of complexity outside of very narrow domains. This failure has been a major obstacle to the development of systems that harness human reasoning with a computer's tireless attention to detail. We propose to investigate why knowledge engineers need to be in the loop, and provide requirements and high-level design to addresses many of these problems. Our focus will be on interfaces that operate in the SME's domain of discourse. As a concrete example, we will be looking at a mixed graphical/textual representation of the intelligence analysis process whereby complex rules can be expressed as simple questions in a context inherited from the workflow. Our experimentation to date has found that this representation is not only very intuitive for SMEs, but is also highly productive in comparison to more conventional rule-construction methods.

Title:See Thru the Wall Technologies
Abstract:This Phase I SBIR project addresses the development and feasibility evaluation of handheld and vehicle-mounted see-thru-the-wall (STTW) capability combined with non-lethal weapon (NLW) through the use of infrasound technology that meet the Army needs and as a key element for the Future Combat System (FCS) and is spelled out in the FCS Operational Requirements Document (ORD). The work involves investigation of underlying infrasound technology as applied to STTW applications (STTW-ISCAP) and NLW applications (NLISW). The STTW-ISCAP and NLISW are combined in a Infrasound Standoff Combat Capability (ISTACC) wherein they share a single platform with displays and controls and possibly other components. This allows for combined combat operations as well as activation of one or the other dependent on the situation. The Phase I will determine the size, weight, power, component technology, and standoff capability achievable based on the limiting physics. Components-off-the-shelf (COTS) will be utilized as much as possible in the implementation. Use will be made of the ground work that has been done by Department of Energy in the area of location of objects and faults in the earth as well as the work performed in the medical field research on the effect of infrasound on human.

Title:ULTRASENSITIVE SCALABLE PERIMETER DETECTION SYSTEM WITH DIRECTION FINDING CAPABILITY
Abstract:A novel technique for perimeter detection (PD) system is proposed here for the first time, which is passive and undetectable (buried in ground), very sensitive (can measure sub-micron strain), fast (> 40 Hz), scalable to large encampments (> 2 km), low-cost and rugged, and has direction-finding capabilities (including a potential for finding angular direction and movement towards or away from camp). This technique promises a new generation of PD system, which has high sensitivity, large bandwidth, environmentally rugged, immune to electromagnetic interference (EMI), lightweight, small size, easy to install, and high scalability. This novel technique is insensitive to temperature effects, and can senses precise location of the intrusion within a few meters. The precise location and direction sensing, and undetectability of this technique would provide early warning without its knowledge to the intruder, and would increase the effectiveness to tackle the intruder by increasing the reaction time. This PD system can be strategic to the military for the protection of military encampments especially in foreign land, and for homeland defense applications such as for protecting nuclear plants, high-security buildings, airports and other key structures.

Title:Wind-Blown Clutter Mitigation to Improve Ultra High Frequency (UHF) Moving Target Indicator (MTI) Performance
Abstract:For stationary ground moving target indication (GMTI) radars, targets are generally isolated from clutter under the assumption that the clutter background is non-moving and therefore exists only at zero Doppler while moving targets will appear at non-zero Doppler shifts. In reality the background clutter will often have a non-zero bandwidth due to the presence of wind-blown foliage such as trees and shrubs and thus occupy Doppler filters other than the zero-Doppler filter. This results in degradation of the detection performance for slow moving targets resulting in minimum detectable velocity (MDV) performance of a radar system that varies as wind conditions change. For example, when the wind is blowing the clutter will occupy additional Doppler filters resulting in the obscuration of some moving targets that would otherwise be detectable under calmer wind conditions. The main goal of the proposed research is to develop techniques to enhance system performance by estimating clutter Doppler spread directly from the radar data in "real-time" and apply that knowledge in detection and tracking filters to reduce false alarms while maintaining system sensitivity. It is anticipated that the algorithms developed under the proposed effort will improve system performance by applying real-time characterization of the clutter Doppler spread due to wind-blown clutter during a given coherent processing interval (CPI).

Title:Selective Localized Global Positioning System (GPS) Denial
Abstract:The proposed Phase I research will define and evaluate the technical feasibility of a novel concept for selectively denying the use of GPS by adversaries. The goal is to provide mobile military units a flexible GPS denial system that can operate both autonomously and in a coordinated, network-centric, manner. Termed the GPS Selective Denial System (SDS), the proposed concept will equip mobile units with the capability to target specific regions and/or adversaries, denying them the use of GPS while still enabling our own forces continued service. The SDS is a fully programmable, beam steerable, jamming system that utilizes a high-quality frequency reference and monitoring of the GPS to produce a variety of jamming signals designed to disrupt an adversary's GPS service. At the same time, receivers equipped with the appropriate anti-jam components (termed the SDS Decoder) and apriori knowledge of the jamming scenario can effectively eliminate the jam, enabling normal operation without major degradation. The proposed research will develop this concept in accordance with known requirements in preparation for a Phase II implementation. Research will consist of theoretical analysis, requirements analysis, systems design, and simulation testing. Feasibility will be assessed by analyzing expected performance, complexity, production costs and anticipated benefits.

Title:Silicon Light-Controlled Passive Elements for High Speed, High Power Electronics
Abstract:The U.S. Army needs new tunable electronic components for high-frequency high-power devices such as RF power amplifiers and other devices and subsystems in the Future Combat System. These components must have extended tuning range and fast response to control signals. To meet this Army need, Physical Optics Corporation proposes to develop a new Silicon Light Controlled (SiLC) switching technology, in which several passive elements can be combined either in parallel or in series with low induced losses for high-frequency signals. The induced losses will be reduced by fully separating the high-power circuits from the control signal circuit. Light-induced conductive bridges between passive elements will be created in specially formed charge-confining area on silicon wafer by highly efficient vertical cavity surface emitting lasers (VCSELs). The proposed technology will bring great flexibility to circuit design for both existing and future passive electronic components. In Phase I, POC will demonstrate a fully operational SiLC switch model; Phase II will be devoted to technology optimization and to fabrication of tunable elements for immediate integration into Future Combat System devices.

Title:Low Probability of Intercept/Low Probability of Detection (LPI/LPD) and Radio Frequency Interference (RFI) Mitigation Techniques
Abstract:RFI and signal security are indelibly intertwined in military FOPEN radar systems. RFI is a dual problem for FOPEN radars: on transmit, the radar signal interferes with other friendly systems operating in the same band; on receive, these systems' signals interfere with radar operations. A common solution to dealing with both RFI manifestations is to notch the RFI signal. However, a piori knowledge of the spectral characteristics of the friendlies in the region, which is acquired by a "sniff" mode or is available before radar operations, is crucial. Furthermore, notching distorts the received signal, degrading the performance of the radar, if not corrected for. TSC proposes an LPI/LPD waveform design to alleviate the RFI problem with minimal distortion when RFI information is available, while providing signal security. When information is unavailable, RFI is detected, notched, and autoregressive filtering applied to recover the target signals. TSC has investigated and developed a variety of LPI/LPD waveforms in the past, and applied AR techniques to recover corrupted SAR and other radar signals. During Phase I, TSC will investigate the feasibility of these RFI mitigation techniques, and develop tools and plans for Phase II demonstration tests utilizing a GeoSAR UHF transmitter in TSC's possession.

Title:Global Positioning System (GPS) Interference Electronic Support Measure (ESM) Payload for Unmanned Aerial Vehicles (UAVs)
Abstract:The availability of low cost global positioning system (GPS) jammer systems provides the potential for an adversary to severely limit the utility of one of the United States' most important navigation and timing resources. During the recent conflict in Iraq, GPS jammer systems developed by the Russian Aviaconversia Company were believed to have been used by the Iraqi Defense Forces. A system that provides accurate GPS jammer geolocation in an affordable, small size, weight, and power package will allow US forces to quickly relay information to decision makers so that an appropriate response can be formulated to eliminate or mitigate the source of the jamming signal. To meet the needs of the Army a GPS Jammer Geolocation Payload for Unmanned Aerial Vehicles (UAV) that provides high accuracy geolocation of the GPS direct sequence spread spectrum (DSSS) signal while to continuing to provide navigation information in the presence of GPS jamming will be designed and prototyped.

Title:Low-Loss Synthetic Aperture Radar (SAR) Data CompressionComplex SAR Image Compression for Automatic Exploitation
Abstract:SAR (Synthetic Aperture Radar) systems have proved to be invaluable for many applications, both military and commercial, including automatic target detection and recognition (ATD/R), terrain mapping, change detection, battle damage assessment, and moving target refocusing and detection. The proliferation of SAR systems, along with the dramatic increase in on-board data gathering and processing rates, places an onerous burden on the communication links that transmit SAR data to groundstations for analysis. SAR-specific data compression may alleviate this problem, but compression must not adversely affect downstream automatic exploitation applications (e.g., ATR) that must mine the data for information. These applications require not just the viewable SAR magnitude image, but the full complex image. Previous SAR compression work is lacking in that it deals only with magnitude imagery, and does not measure the effect of compression-induced degradation on downstream applications. ALPHATECH proposes to use innovative approaches to complex SAR compression to develop real-time capable, deeply-compressing algorithms tuned to SAR exploitation applications. Key to algorithm design is an upfront analysis of exploitation application sensitivity to compression-induced degradation, where we quantitatively measure sensitivities by playing degraded imagery through ALPHATECH-owned exploitation applications, including ATD/R, registration, coherent and non-coherent change detection, super-resolution and moving target focusing.

Title:Optical Components to Reduce Retroreflection from Uncooled Infrared Focal Plane Array
Abstract:The use of long wave infrared (LWIR) sensors is limited in many covert environments by their unacceptably high reflectivity. The high reflectivity makes them susceptible to detection by search CW laser systems. There are many traditional methods for the reduction of optical signature, but most adversely affect the final system image quality and are not cost effective for large volume applications. CDM Optics has an innovative method for redistributing the reflected intensity while retaining high image quality with reflectivity reductions of 4 orders of magnitude being possible. The technique called Wavefront Coding has previously been used to realize other system benefits such as a reduction in system complexity, a reduction in system size, cost and weight, passive athermalization with a simple housing and an increase in imaging volume where the user can clearly see targets simultaneously over a large range of object distances. The Wavefront Coding low-reflectivity concept can be fused with these other benefits to realize a system with superior performance and a favorable benefit to cost ratio. Additionally, the methodology and the specific optical design can be applied across any platforms that use a sensor with the same geometry and can be cost effective through the utilization of moldable IR materials.

Title:Optical Components to Reduce Retroreflection from Uncooled Infrared Focal Plane Array
Abstract:Telic Optics proposes to develop optical components for use in reducing retro-reflections from uncooled focal-plane arrays in the low-reflectivity uncooled camera systems. Specifically, Telic proposes to design and manufacture prism systems that can be used in conjunction with lens systems and uncooled FPAs in a low-reflectivity camera-system design. The prisms operate by deviating the line of sight so that chief rays strike the FPA surface at an angle, and light reflected off the FPA does not exit the optical system. Telic will design prism systems based on the optical parameters presented in the solicitation. Telic will manufacture prototypes of one or more promising prism designs to demonstrate image quality and beam deviation angle. The anticipated outcome is the identification and feasibility demonstration of one or more prism systems that will greatly reduce the retro-reflection from uncooled FPAs while having minimal effect on basic system performance. Telic Optics has already performed significant research in this field. We have previously designed retro-reflection-reducing prisms systems for common-module and SADA detector arrays. We have also previously designed and manufactured retro-reflection-reducing devices for cooled MWIR FPAs. This prior experience provides a high level of confidence in the success of this proposed Phase I project as well as the anticipated Phase II and Phase III successor projects.

Title:Uncooled Infrared (IR) Camera with High Resolution Zoom
Abstract:ISC has successfully developed algorithms that utilize micro scan techniques for a variety of applications. The first of these required a large computing system to convert real-time FLIR imagery for stabilization in an air platform. The technology was further developed to do non-real-time resolution enhancement to evaluate surveillance video. A commercial product was developed known as "Redhawk"T that provides high-resolution still images from video data streams. Processing technology has advanced to the point that full-rate video can be processed to achieve resolution enhancements in real-time using the ISC-developed algorithms for micro scan. While most of the effort has focused on RS-170 type analog video streams, the process works better with digitized data that can be made available from the more customized processing of thermal cameras. The proposed program will adapt the prior algorithms to the digital video stream of thermal imaging microbolometers to convert 320x240 data into the equivalent of 640x480 or higher without the loss of sensitivity. ISC intends to update the key algorithms and verify them on an existing 320x240 camera. With that success, a study will be made of how newer generation 640x480 cameras could be further enhanced for the longer-range weapon environments.

Title:Land Mine Detection by Time Reversal Acousto-seismic Method
Abstract:The objective of the proposed research is to develop new technologies based on principles of Time Reversal Acoustics (TRA) that will provide highly sensitive land mine detection. We suggest applying the Time Reversal Acousto-seismic method in combination with a nonlinear acousto-seismic mine detection technique. The TRA focused system provides a high concentration of seismic wave energy at any desired point (e.g., on a land mine) and can detect it due to the high nonlinearity the mine produces. It is the only system that is capable of focusing seismic waves in time and space, which highly increases the detection abilities of linear and nonlinear acousto-seismic methods. Several systems based on TRA focusing (with speakers and small seismic vibrators) for laboratory and small-scale field tests will be developed and tested. Measurements of the surface vibration will be conducted by a scanning laser vibrometer and contact sensor. TRA spatial and temporal field structure, its dependencies on the frequency of radiated waves, distance from radiators, and the number of radiators will be investigated. High harmonic generation, due to nonlinear contact between the mine and the surrounding sand/soil, will be used for mine detection. Feasibility tests will demonstrate the abilities of TRA for land mine detection.

Title:Landmine Detection
Abstract:Buried landmines produce distinct seismic surface vibrations when excited by acoustic or pressure energy. Many approaches to this problem are being investigated. To date the biggest problem is the slow demining rate due to dwell time requirements. The platform speed is governed by the necessary dwell time (100 ms for 10 Hz resolution) and the number of simultaneous measurements. To support a 1 m/s platform velocity with a 3 m wide swath and 2 cm resolution, a total of 5x150 beams (pixels) is required. Faster platform velocities are conceivable through a larger array. In principle a 25x150 array would support a 5 m/s platform velocity. CTI proposes to develop a novel scannerless acoustic landmine detection system using a coherent detection receiver to detect these minute surface vibrations on a moving platform. At present CTI is carrying two conceptual designs to be down-selected in Phase I. The first concept is a multi-channel conventional bistatic CW laser vibrometer. This multi-channel/beam lidar increases the demining rate through parallel beams. The second and more novel concept is a baseband imaging interferometer, which utilizes a low-noise high-speed CCD camera to image an interfereogram, thereby significantly reducing hardware complexity. Speckle mitigation is achieved through the a series of diversity techniques, which include some combination of the following : dual polarization receiver, multiple receive apertures for each transmit beam, multiple wavelengths, and temporal averaging. The sensor also employs platform motion sensors and advanced signal processing algorithms to optimally process the speckle diversity and mitigate platform motion induced noise. A post processor filters the data using knowledge of the mine-signatures to produce the mine detection signal.

Title:Off-Route Mine Detection
Abstract:There is a growing threat of side-attack mines that attack vehicles and personal from the side as the target passes by. The ability to detect mines that are concealed by camouflage or foliage at distances of 200 meters with a high probability of detection, high clutter discrimination, and low false alarm rate and at rates that a convoy travels is essential to the systems success. This proposal entails the development of state of the art off-route mine detection technology capable of detecting existing and next generation off-route and side-attack land mines. The proposed solution uses commercial automobile collision warning radar equipped with a fixed monopulse antenna to search the roadsides for potential targets. By measuring the difference between the Radar signal level returned or reflected from a side-attack mine and or explosive and the expected signal level returned or reflected from the roadside, it is possible to exploit that difference to determine normal environment from potential threatening environment. The proposed solution efforts will address one or more of the following: detection of the threat, self-calibration, no requirement to re-trained system for each new weapon or configuration, low cost, light weight and simplicity of operation.

Title: A High Performance, Low Cost, Compact, and Wireless E-nose System for Explosives Detection
Abstract:Detection of non-buried explosives is of great significance to both military and homeland security. Although many existing sniffing devices may be used for explosives detection, the size, cost, weight, and portability are primary concern in the development of a field deployable sniffing devices. Herein we propose to build high performance, low cost, compact, and wireless e-nose devices for explosives detection. The system has three key features. First, we have identified an e-nose chip family, developed by Cyrano Sciences, Inc. In addition to small size and low cost, the chip has a wireless capability, which makes the wireless data retrieval possible. Second, we propose to use Support Vector Machines (SVM) to improve the accuracy of explosives classification and nonlinear unmixing for accurate explosive concentration estimation in a mixture. SVM has several attractive advantages and better classification performance than most other classifiers. Most existing unmixing methods are linear in nature. However, our proposed unmixing is a nonlinear approach, which addresses the nonlinear relationship between e-nose responses and different explosive compounds. Finally, we will use a PDA to wirelessly collect the e-nose sensor reading and analyze the data. We believe that our proposed system can find many applications.

Title:Super-Sensitive Explosives Detector
Abstract:Ion Mobility Spectrometers (IMS) are sensors used extensively to detect trace volatiles of explosives and chemical weapons. Developed in the 1970s, IMS has become a mainstay of explosives detection technology due to its low cost, rapid response and high sensitivity (parts per billion). Nonetheless, there is compelling need to develop more sensitive sensors that are field-deployable to meet the challenges of countermine and anti-terror defense. Greater sensitivity will enhance ability to detect explosive volatiles at greater distance from the source of emanation and will also enable detection of advanced explosives having low vapor pressure. We propose to develop a new form of IMS instrument based on Differential Mobility Analysis (DMA) to meet these challenges. Whereas IMS separates ions in time, the DMA separates them in space. This fundamentally new approach offers important advantages including potential for significantly enhanced sensitivity (

Title:Near Infrared Streak Tube Development
Abstract:The Streak Tube Imaging LIDAR (STIL) combines streak tube and CCD imaging technology to yield high-resolution 3D imaging systems. The technology was developed primarily for ocean imaging and the operational wavelength is around the blue green portion of the visible spectrum. However, laser eye safety requirements and the need for covert operation preclude operation at a visible wavelength. Arete proposes to join emerging transferred electron (TE) photocathode technology with a high temporal resolution streak tube design to extend the STIL operating range into the near infrared. The near infrared streak tube design relies on the use of high quantum efficiency InGaAs/InP photocathodes. The proposed development effort will produce an integrated design of a near infrared STIL receiver capable of operating near the eye-safe wavelength of 1.55 microns. The result of the combined Phase I and Phase II efforts will produce a component that allows STIL technology to be applied to military and commercial laser radar problems where operation in the NIR is essential.

Title:Near infrared streak tube imaging lidar receiver
Abstract:The Streak Tube Imaging LIDAR (STIL) combines streak tube and CCD imaging technology to yield high-resolution 3D imaging systems. The technology was developed primarily for ocean imaging and the operational wavelength is blue green. However, STIL and STIL derivatives have been demonstrated to be a powerful technique for generating high resolution 3D imagery in littoral, terrestrial and atmospheric applications but eye safety requirements and the need for covert operation preclude operation in the visible. Arete proposes to develop an advanced wavelength converter to extend the STIL operating range into the near infrared. The converter relies on the use of high quantum efficiency detectors (e.g., InGaAs arrays), VLSI analog electronics and Vertical Cavity Surface Emitting Lasers to accomplish the conversion. A proof of concept experiment demonstrated high bandwidth range resolved measurements in the laboratory. The proposed development effort will build and test a prototype converter system that will elucidate design issues in a risk-controlled manner, yielding a high probability of success in Phase II. The result of the combined Phase I and Phase II efforts will produce a component that allows STIL technology to be applied to military and commercial laser radar problems where operation in the NIR is essential.

Title:Security for Wireless Handheld Devices
Abstract:DAT, Inc. has invented and developed an authentication technology that employs as the source of a shared secret a source of dynamic entropy whose origins lie within chaotic, natural physical processes. By using a secret whose value is based on location and must be measured at that location, DAT has been able to add new layers of control to the authentication process. These new layers of control effectively add two new access control credentials: - where have you been - where are you now The DAT technology can be employed to provide a location-based authentication system that cannot be spoofed, predicted or otherwise subverted. The technology combines this powerful, location-specific random entropy (noise) with known technologies in a unique way to provide a powerful new method of user and data packet authentication that is based on location. DAT proposes to study the uniqueness of these signatures in a wireless environment in order to discriminate between approved and unapproved users for granting access to a LAN. Issues such as building construction, activity within the RF spectrum, spatial granularity and temporal stability will all be examined.

Title:Security for Wireless Handheld Devices
Abstract:The XPRT Solutions,Inc./New Jersey Institute of Technology /Network Security Solutions, Inc. (XNN) team proposes to prototype the Locally Enforced Global Trust (LEGT) strong authentication technique for handheld wireless devices in a Mobile Ad-hoc Network (MANET) or in a Future Combat System (FCS) environment. MANET/FCS nodes can operate in a decentralized "trust no peer" mode that complicates and inhibits security services. Phase I is used to refine the design of LEGT, whereas Phase II will develop a prototype, then test and evaluate its performance against realistic red-team scenarios using our laboratory testbed that also emulates Future Combat Systems (FCS) scenarios among others. The XNN team has constructed and tested successfully a solution architecture to the provision of security in MANETs that is based on a "neighborhood watch" concept. LEGT utilizes this architectural approach, along with known successful principles of authentication that include self-organized PKI with certificate chains over clusters, threshold cryptography with localized trust, distributed trust, and cluster based key management, thus building a fully decentralized scalable strong authentication policy.

Title:Terrain Aware Network Planning Tools
Abstract:The objective of this proposal is to research, develop, and prototype a lightweight network planning tool with an embedded modeling and simulation capability to support future Army tactical communications networks. This new lightweight tool will be notebook computer-based, allowing soldiers on the battlefield to quickly analyze the combined effects of network topology, terrain, propagation, and node mobility to perform dynamic network planning and course of action studies. The Army's Objective Force (OF) and Future Combat Systems (FCS) Programs will enable the Warfighter to conduct network-centric warfare with multiple communications assets to achieve information superiority and mission success. A lightweight, simple to use, network planning tool will enable the Warfigther to design and provision tactical mobile ad hoc networks, rapidly validate and verify networks on the move, and study alternative courses of action based on the battle plan, node mobility, situational awareness, RF propagation, and terrain data. Modeling and simulation (M&S) offers many benefits to the DoD including the ability to evaluate and optimize C4ISR systems in a variety of pre- and post-deployment scenarios. Currently, there is no available COTS M&S software that can effectively utilize terrain, propagation, node mobility, weather, network topology, and traffic data to support the Army's requirements for rapid network planning using a lightweight, field deployable PC. OPNET's proposal focuses on approaches to solve this problem (based on simulation techniques and non-simulation based "point" tools) and also describes key attributes of the prototype Terrain Aware Network Planning Tool that will result from this Phase I SBIR program.

Title:Network Protocols for Onboard Satellite Packet Routing
Abstract:The objective of this proposal is to develop packet switching protocols capable of providing efficient network access to satellite resources with the intention of passing IP traffic across onboard satellite routers and switches. Stratogis propose to use existing software capabilities to quantitatively assess the impact of design decisions on analytic performance parameters and perform system engineering trades to assess the impact on qualitative performance parameters. After defining key design trades, typical performance parameter requirements, sample network requirements scenarios and a baseline reference architecture, Stratogis will parametrically analyze performance of key design trade parameters such as Layer 2 vs. Layer 3 onboard switching/routing and INTSERV vs. DIFFSERV QoS protocols using existing OPNET-based simulation tools. The performance for each option will be compared with target requirements. In addition, Stratogis will evaluate TCP accelerator and bandwidth-on-demand DAMA protocols. Performance metrics will include quantitative parameters such as latency, packet loss, and throughput as well as qualitative metrics such as manageability, ease of integration and scalability. The results will be documented in a forward looking architecture document describing operational and technical requirements for both space and ground components of network architecture.

Title:High Efficiency Waveform for Small-Aperture, Mobile, Satellite Communication Networks
Abstract:The proposed research is to develop an overall system design for a power- and bandwidth efficient satellite communication modem, a communication waveform and an associated Medium Access Control (MAC) protocol to realize efficiency improvements. In currently deployed networks a single modulation scheme is typically used to communicate with all the users in the network, thus requiring a communication waveform designed to serve the most disadvantaged user. Given a typical mix of locations within a Ka-Band spot beam (e.g. at the center of the coverage area vs. the edge of the coverage area), local propagation conditions (e.g. local rain fade), and antenna sizes, current system designs typically result in allocation of 5-9 dB of excess link margin to the vast majority of users. Implementing the proposed waveform and modem that support dynamic, variable resource allocation can improve network capacity by a conservative factor of 3 to 5. Currently deployed networks typically base the return link on a Time Division Multiple Access (TDMA) waveform, which requires tight synchronization of terminals and a transmitter with high RF output power. The proposed implementation employs a spread spectrum return link that mitigates synchronization requirements and reduces the required RF output power, resulting in a more economical terminal design.

Title:Sensor Node Radio (SNRadio) for Ad Hoc Sensor and Munitions Networks (9640)
Abstract:Q-DOT proposes to develop a low-cost, low-power, Sensor Node Radio (SNRadio) specifically designed to support ad hoc sensor and miniature networks for FCS and OFW. It supports ad hoc sensor and munitions network protocols. The SNRadio provides the first link in communication paths between the Sensor Node and the User. The SNRadio maximizes sensor time-on-station by minimizing network communications power requirements. Its DSSS waveform facilitates LPI, LPD, jam-resistant communication at 1 Mchip/second. The proposed SNRadio is realized completely with COTS components built around R.F. Monolithics' (RFM) ASH 3 Transceiver. RFM claims that the ASH 3 receiver consumes less power than any other receiver in the world at any given bit rate. Q-DOT will conceptually design network protocols and a secure waveform in Phase I to project SNRadio size, cost, power consumption, and performance. (Separately, Q-DOT proposes to develop the next generation ASH 4 transceiver (under Topic A03-121) which is specifically tailored to support ad hoc sensor networks.) A network of SNRadios coupled with a COTS sensor package will be designed, built, and demonstrated in Phase II.

Title:Digital Predistortion at RF using Superconductor Electronics
Abstract:HYPRES proposes to develop an RF-in-RF-out linearizer module that can be easily incorporated into existing radio systems for direct predistortion linearization of broadband (>100MHz), multi-carrier power amplifiers, over the 2MHz-2GHz range for the Joint Tactical Radio System (JTRS). This module will enable the use of higher-efficiency, but strongly non-linear, power amplifiers, as well as improve the spectral purity of the broadband transmit waveform. HYPRES will exploit fast (20-40GHz), high-linearity superconductor analog-to-digital and digital-to-analog converters and ultrafast digital logic circuits on an integrated multi-chip module to perform digital predistortion correction directly on the RF waveform. In Phase I, we propose to develop a new digital-RF predistorter that uses proportional, integral, and differential (PID) correction to compensate for rapid (10 GHz bandwidth) signal-dependent variations of the amplifier's non-linear transfer function, to achieve maximum suppression of intermodulation distortion. Neither narrowband analog RF electronics, nor slower semiconductor digital electronics, can achieve the necessary suppression. In Phase II, starting with a Phase I Option, we will design and demonstrate the PID digital-RF predistorter on a superconductor multi-chip module (MCM).

Title:PAMELA: Propagation Analysis and Modeling Experiments for Laser Applications
Abstract:Laser communication has enormous potential to provide a secure, jam-resistant, low detection probability and high-bandwidth means to support multimedia, imagery, video, mapping and other command and control functions in battlefield environments. We propose to develop a complete numerical model for lasercom links, which will predict the performance and evaluate tactical feasibility of lasercom links, guide link design, evaluate the efficiency of scintillation mitigation techniques, and identify areas where further research is required. During the Phase I program we will evaluate jointly with researchers from ARL/NRL an approach for estimating the vertical profile of the structure parameter based on its values predicted by the turbulence model in the surface layer. We will develop a model for a closed-loop optical tracker, total link budget analysis, and aero-optics effects in the lasercom link. We will integrate this model with the wave-optics code for propagation through turbulence, and evaluate the performance of the Tera Hertz Operational Reachback (THOR) communication links. In addition, we will validate the efficiency of the mitigation techniques to reduce turbulence-induced signal fading in the communication links and develop a top level software architecture to provide a complete model of military laser communication.

Title:Smart Single or Multiple Beam Forming Antennas in the 1 to 2 GHz Range
Abstract:The Joint Tactical Radio System (JTRS) needs multi-band airborne and ground vehicular antennas that can cover all JTRS bands over 1-2.5 GHz and have steerable beams. The difficulties in developing these antennas are due to the requirements of not only multi-band/broadband to cover 1-2.5 GHz, but also low-profile and conformability suitable for mounting on a military airborne and/or ground platform, as well as an affordable cost for inherently expensive beam steering. Fortunately, Wang Electro-Opto Corporation (WEO) has recently developed an airborne multiband/broadband array antenna having performance and features generally similar to the requirements of this Army SBIR program, Topic A03-120, as well as affordable costs. The main differences are the wider operating frequency range and the specific JTRS bands in this SBIR program. Based on this new technology, Wang Electro-Opto Corporation (WEO) proposes to develop a smart beam-forming antenna operating throughout the 1-2.5 GHz JTRS bands. The initial design is for single-beam with multiple-beam features to be added later if desired.

Title:Networked System-on-a-Chip for C4ISR (9643)
Abstract:Q-DOT proposes to investigate the feasibility of developing a fully integrated system-on-a-chip for sensor-based C4ISR networks. In Phase I, a prototype Sensor Node Radio (SNRadio) will be conceptually designed based upon the commercially off-the-shelf (COTS) ASH 3 Transceiver produced by RF Monolithics, Inc., in Dallas, Texas. The ASH will provide the small, ultra-low power, RF communications link between various sensor nodes. The SNRadio maximizes sensor time-on-station by minimizing network communications power requirements. RFM claims that the ASH 3 receiver consumes less power than any other receiver in the world at any given bit rate. Under software-control, a DSP and a micro controller will enable the SNRadio to participate in ad hoc sensor and munitions networks. (Under a separate proposal submitted under Topic A03-117, Q-DOT proposes to investigate the waveforms and protocols required to create ad hoc networks using the SNRadio.) Link analyses will be performed for potential operating environments to help select an optimal operating frequency and to predict the achievable link distances. In Phase II, the detailed design of the prototype SNRadio will be completed. Upon successful demonstration of the prototype early in Phase II, the design of the next generation ASH Transceiver (ASH 4) will begin in order to enhance performance and integrate as much of the SNRadio functionality onto a single SiGe BiCMOS chip as possible. The ASH 4 development will be completed and demonstrated in the next-generation SNRadio during Phase III.

Title:Networked System on a Chip for C4ISR
Abstract:The overall goal of the Reconfigurable Networked Smart System on Chip (ReNSS) is to provide a network-oriented C4ISR chip. This will include designing (1) energy-efficient, intelligent sensor processing and fusion modules, (2) reconfigurable hardware for reliable communication and processing capabilities, (3) routing algorithms for a self-organizing network, and (4) an innovative fabrication method to combine these technologies onto a single energy-conservative VLSI chip. To advance the networking and C4ISR system capabilities further, this innovation can provide self-configuring, self-healing, fault-tolerant communications that also communicate with the fixed, wired network infrastructure. This hybrid network architecture enables sensors or C2 reporting and messaging functions to collect and process data both independently and cooperatively, as opposed to the centralized HOST data processing approach. The proposed solution focuses on reducing the latency of Network Reconfiguration in a distributed control infrastructure for component-level-based automation systems. It also will allow the creation of self-forming networks that can expand and contract on demand, extend into damaged areas with unknown infrastructures, and communicate between ad hoc elements as needed. Finally, the proposed effort will consider emerging automated tools for specification, design, implementation, testing, and verification for the chip design and development process.

Title:Orthogonal Coding for Code Division Multiple Access (CDMA)
Abstract:We propose to develop and assess an Orthogonal CDMA cellular communications system that capitalizes on the advantages associated with a unique pseudonoise (PN) code class identified as "Multiplexed Noise" (MN) codes. Employing MN codes for CDMA eliminates all of the major disadvantages of present CDMA systems that employ Maximal Length Sequence (MLS) codes. Those systems are forced to be non-orthogonal and process only a short segment of the MLS code. Obtaining orthogonal operation eliminates the near-far ratio problem and need for power control. This provides the maximum attainable capacity of n (n = the code length) users per cell or sector with no interference between any of the users. Optimum AJ and LPI/LPD is provided with a guaranteed processing gain performance improvement of n for every processed code. We will identify and develop proprietary concepts that can accommodate multiple data rates for spread spectrum systems such as used in LANs and in Future Combat Systems. This provides significant processing gain even for the high data rates associated with video. Using MN codes is still optimum here and several proprietary concepts we have enable combining inputs at different rates and maximizing the code lengths to obtain optimum AJ and LPI/LPD performance.

Title:Automated Wafer Polishing for Epi-ready CdZnTe Substrates
Abstract:MCT grown on CdZnTe substrates is the dominant material for infrared photon detectors. However, the technology for polishing CdZnTe substrates to the quality demanded by molecular beam epitaxy (MBE) does not currently exist in the United States. EPIR Technologies proposes to develop a technology for substrate polishing by (1) creating an advanced chemical polishing procedure for CdZnTe (2) creating a post-polish annealing procedure, and (3) growing MCT by MBE and fabricating photovoltaic devices. CdZnTe substrates that were previously used for MCT growth by MBE will be stripped of their MCT layers and polished (i.e. substrate reclamation or reclaiming). The reclaimed substrates will be characterized by atomic force microscopy, etch-pit density, profilometry, Hall, FTIR, and x-ray diffraction in the base period. In the option period, transmission electron microscopy will be employed to evaluate the atomic structure of the reclaimed substrates, and MCT heterostructures will be grown on the substrates. The development of this reclaiming technology will greatly reduce the cost of MBE-quality CdZnTe substrates and increase the yield of good MCT layers grown on CdZnTe by MBE. EPIR is committed to the development of MCT MBE technology and is the only commercial vendor of MCT by MBE in the United States.

Title:Development of Automated Batch Polishing and Reclaiming System for Epi-ready CdZnTe
Abstract:MATECH will demonstrate, during Phase I, the capability to polish CdZnTe substrates to state-of-the-art EPI-ready quality. MATECH has already demonstrated a preliminary capability to produce EPI-ready material of superior quality. Phase II will automate and deliver a system capable of automated simultaneous polishing and reclaiming multiple substrates of sizes up to, at least, 70x70mm. MATECH will demonstrate that the polished CdZnTe substrates have a rocking curve virtually undistinguishable from the bulk material, as well as suitable topography as determined by AFM. At the core of the proposed effort is a novel, modified, non-contact chemical polishing process capable of producing consistent EPI quality CdZnTe substrates from ground material. This is a very important advance because, since the polishing is done purely by the chemistry and no abrasives are involved, mechanical subsurface damage and other structural defects caused by the polishing media and mechanical process are entirely avoided. MATECH has developed other materials, processes and systems for the Government before, and has successfully introduced most of them into commercial manufacture. MATECH has been featured in the Missile Defense Agency (MDA) 2002 Antiterrorism Technologies Report, on the cover of its 2003 Technology Applications Report, and in its Summer 2003 No.46 MDA Update.

Title:Improved Infrared Screening Smoke Particles Using Single-Wall Carbon Nanotubes
Abstract:There is a continuing need for effective obscurants at infrared frequencies and below. In particular, the infrared screening effectiveness of current smoke materials needs to be improved by an order of magnitude based on the extinction cross section per volume of material. Foster-Miller, Inc., proposes overcome these deficiencies by developing improved infrared screening smokes using single wall carbon nanotubes (SWNTs). Foster-Miller will use its proprietary methods for dispersing and forming SWNT ropes that will meet the performance objectives for infrared screening smokes. During this Phase I program, Foster-Miller will produce grams of modified SWNTs and disperse these into a liquid media for infrared spectroscopic cell analysis of the extinction coefficient to demonstrate the technical feasibility of its approach. It will also demonstrate that during the time frame of the Phase II program, its teaming partner, Carbon Nanotechnologies, Inc. (CNI) will be in a position to provide high quality SWNTs at quantities and prices required for this application. (P-030597)

Title:Multidimensional Microfluidics for Mapping Post-Translational Modifications
Abstract:This proposal aims to develop and validate a multidimensional protein separation platform based on polymer microfluidics technology which will be capable of mapping a wide range of post-translational modifications (PTMs) in complex protein samples. The proposed system employs three separation dimensions, namely: IEF, SDS gel electrophoresis, and MALDI-MS. The platform will combine IEF and SDS gel electrophoresis on a single microfluidic chip, with chip-level laser-induced fluorescence detection to record the separated protein positions, and an integrated electrospray tip array to elute separated protein bands from the chip onto a MALDI target plate for MALDI-MS analysis. On-target proteolytic digestion will be performed using two different enzymes to ensure a high degree of peptide coverage during MS analysis. This detection platform will eliminate the manually-intensive process of running standard 2-D gels, while also eliminating the sample dilution associated with traditional 2-D PAGE / MALDI-MS interfacing. Furthermore, the system is expected to provide complete 3-D separations in ~1 hour, approximately an order of magnitude faster than traditional 2-D PAGE / MALDI-MS, with greatly improved PTM analysis capabilities in a miniaturized format.

Title:Separation Technology for Glycoproteins
Abstract:The successful identification, production, and purification of useful proteins (e.g., organophosphorous hydrolase) would allow for its incorporation into sensors, armor and equipment for soldiers, helping to improve soldier health and performance. Large portions of proteins undergo post-translational modification, resulting in a varying degree of protein function. The range of modifications that glycoproteins may undergo is vast due to the number of potential carbohydrate moieties that a protein could accept. Current separation and detection technologies have proven insufficient for dealing with glycoproteins; therefore, there is a great need for developing new separation techniques and/or technologies that can add a third dimension of separation for glycosylated proteins and other modified proteins. Lynntech proposes to develop a novel system capable of separating various levels of glycosylation within a targeted protein family, through the use of a novel carbohydrate affinity separation system. In the Phase I project, Lynntech will prove the feasibility of the novel separation system for isolating varying degrees of glycosylation that have occurred in a protein sample. In the Phase II project, Lynntech will build a prototype separation system that can be integrated with current commercially available two-dimensional separation systems to create a multi-dimensional separation system for glycoproteins.

Title:A System Dynamics Approach to Buried Mine/Unexploded (UXO) Detection and Identification
Abstract:Current landmine detection approaches use very little object specific information from the sensor signal. A drawback is high false alarm rates due to large overlaps of the limited feature sets used to distinguish mines from clutter. In this project, we will focus on a model-based approach to feature extraction and pattern recognition for the acoustic-seismic mine detection platform built by University of Mississippi. The acoustic-seismic mine detection approach has shown a lot of promise in detecting low-metallic (plastic) mines that are considered hard to detect by conventional metal detectors and GPR. The motivation of our approach is that by imposing mine/soil model under acoustic-seismic excitation we can perform more robust system identification. This, in turn, will help us extract physically meaningful features for statistical learning and target recognition under limited but noisy data. The main objective of the proposed effort is to investigate candidates of ISSD model that is most suitable for use of mine detection. The requirements for such models are not only accuracy of the models but also identifiability of the models given inquiry signal and sensor data. Our second objective is to develop a parameter estimation method, in parallel with the ISSD model selection. The method is to be used to determine from the collected inquiry signal and detector data any model coefficients that are not known during mine detection operations. The project team consists of Scientific Systems Company, Inc. (SSCI) as the prime contractor, and the University of Mississippi as the sub-contractor.

Title:3D Topology-based GIS Model (TGIS)
Abstract:We propose to research, design, and develop a boundary representation based topological representation model for 3D GIS. The representation model provides a theoretically sound foundation for intra-relation 3D GIS query. The intra-relation includes all encoded topological relationships except disjoint. Also, Octree-based spatial index, Polyhedron approximation based inter-relation GIS query filtering will be integrated with the proposed topological representation. The spatial index uses a 3D space partition concept to scope down a disjoint topological relationship or unencoded intra-relation. Polyhedron approximation for inter-relation query filtering helps reduce frequency of precise 3D computation and improve overall system performance. The rationale is that 3D computation for providing a topological relation sometimes is expensive and unnecessary. Most importantly, we are adopting a 3D topological representation that can incorporate current 2D GIS representations as a subset. Therefore, a majority of current 2D GIS functionalities can be reused in the proposed 3D GIS model. Based on our design, we will take advantage of characteristics of boundary representation and use them to bridge with existing 2D GIS layer schemas. We envision the approach will smooth the migration from 2D GIS to 3D GIS without jeopardizing performance of the proposed solution.

Title:Implementation of a Geospatial 3-Dimensional Topology Model
Abstract:The development of a conceptual design that demonstrates the feasibility for creating, storing, and exploiting 3-D topology in a commercial geographic information system will establish a new standard for the industry. Founding the design on the ISO 19107 Spatial schema standard, issued in 2003, and the Open GIS Consortium's Web Services standards will solidify the development and enable federal and civil organizations to procure standards based architecture. More importantly, the instantiation of a 3D Topology standard in commercial DBMS will provide the enabling tools for software based automated data maintenance in a real 3D world.

Title:Spatial Data Mining Toolkit for Generating Mission Specific Data Sets (MSDS)
Abstract:The Army today must be prepared to embark on contingency and emergency operations with very little advance notice in distant parts of the world. In such an environment, the geospatial information requirements to support operations cannot be accurately or adequately specified until close to the commencement of the mission. To be responsive to the needs of such missions, it is imperative to have a process for the rapid and timely production of Mission Specific Data Sets (MSDS). The traditional manual process for MSDS production is extremely labor intensive and time consuming. There is a need therefore for an automated tool to support rapid generation of MSDS with the required degree of fidelity from lower fidelity data sources. Spatial data mining techniques that have been developed in the recent past represent a key enabling technology for building tools to assist a topographer in rapidly generating MSDS feature data. Leveraging a number of novel spatial data mining techniques, Architecture Technology Corporation will develop an automation tool called TopoAssistant (Topographer's Assistant) to assist Army topographers in building "just-in-time" MSDS. The proposed Phase I effort will develop the architecture and design of the TopoAssistant software tool and establish its implementation feasibility through a rapid prototype.

Title:Clustering and Overlay Analysis for Discovering Spatial Association Rules
Abstract:An explosion of geographic data sets and related processing has occurred in recent years. Spatial data mining techniques are of interest to handle these large volumes of data and to identify relationships between features in a data set. Data mining holds the promise of being able to discover and validate association rules, to quickly determine whether a feature of interest is present, and to predict the existence of missing features. A spatial data mining technique is proposed which can work with data from multiple sources, can handle both numeric and categorical data, and can account for spatial neighborhood effects. This technique uses clustering, overlay, and statistical analyses to determine whether a group of features or attribute values are likely to appear together in a data set, and if so, whether an association rule can be validated between these features. The method will create a representational format for the data, identify both vertical and horizontal relationship types and determine their probability, and test and validate the specific relationships found. The Phase I project will demonstrate the feasibility of this approach, with the purpose of predicting missing features or rapidly identifying significant features in a large data set.

Title:Real-time, Ultrasensitive Water Supply System Biosensor
Abstract:This Small Business Innovative Research Phase I proposal seeks to develop an ultra-sensitive, low-cost, highly-redundant biowarfare (BW) agent sensor for the in-line monitoring of water supply networks. The compact microphotonic sensor will be capable of rapidly (<1 s) detecting multiple BW agents and pathogens via highly-selective DNA and protein-specific interactions. The sensor will provide real-time screening of water distribution systems for numerous targets, providing an on-site, highly-parallel sensor platform that outperforms existing sensor technologies for both small-scale and large-scale water networks. The Phase I research comprises demonstrating the core technology on pathogen simulants, and identifying fabrication formats that are suitable for large-scale manufacturing. The ability to detect waterborne pathogens rapidly with high selectivity will be demonstrated, and embodiments for the Phase II prototypes that are configured for DoD priority targets will be determined. The water screening biosensor will be installed, tested, and qualified at a DoD facility on priority targets during Phase II. During Phase III, the sensor will be adapted for commercial applications comprising military and domestic water quality monitoring systems and portable clinical diagnostic systems for first responders. The proposed real-time sensor system is an ideal trigger technology for proven, yet time consuming diagnostic methods such as PCR.

Title:Sensitive GaN-based Chemical and Biological Detectors for Monitoring of Water Supplies
Abstract:Effective monitoring is critical in protecting populations against the dangers of accidental or intentional contamination of water supplies. For both civilian and military operations, fast-acting remote sensors are needed that can detect a range of possible biological and chemical substances, below toxicity levels in water supplies, and report the results to central computers. Additionally, for troops these sensors should be portable, easy to install, and low-maintenance for long-time continuous operation. In this Phase I project, SVT Associates in collaboration with the University of Florida will demonstrate the feasibility of chemical and biological sensors based on III-nitride optical and electrical devices for fast, reliable and automated monitoring of hazardous materials in water supplies.

Title:A Highly Selective, Low Power, Wireless, Immunoassay Based Optical Sensor for Detection of Water-born Pathogens.
Abstract:There exists a need for near-real time detection and location of small quantities of waterborne biological agents by the warfighter. Since surface water is the primary water source for field soldiers, there is a critical need to determine the extent of potability. The objective of the proposed work is to design and build a small, low cost, highly selective, immunoassay based optical sensor/communication module that can be taken into the field by soldiers to wirelessly monitor streams and effluents for the detection of biological agents. This (Module) will include signal-conditioning circuitry and a radio frequency (RF) transmitter subsection. The signal conditioning subsection will process the raw signals from the sensor subsection and the RF section will transmit a device ID number together with an alarm indication. A soldier, using a handheld reader developed for the purpose, will be able to determine if modules are within communication range and whether any indicate an alarm condition. Work will concentrate on defining: application requirements, optimum target proteins, antibodies, and probes, the support/antibody preparation (membrane) techniques, the optimum packaging/integration strategy, and the means of signal dispersal, communication, and recognition. The work will be performed through a partnership between Sporian Microsystems and Phase IV Engineering.

Title:Modeling and Simulation of Chemical and Biological Agents in Potable Water Systems
Abstract:Modeling the fate and transport of CBR agents introduced into water is crucial to predict the vulnerability of current water distribution systems. Current hydraulics models such as EPANet do a reasonably good job of modeling the transport of pollutants in water. Such codes can be used to model the transport of CBR agents in water distribution systems, provided the material properties and degradation kinetics of these agents are integrated into the code and databases. The degradation mechanisms of interest include agent neutralization due to disinfectants in bulk water and interactions with rough pipe walls. In this study, we propose to carry out lab scale experiments on select simulants for anthrax, a biological agent and VX, a chemical agent to characterize the degradation kinetics due to exposure to chlorine, a common disinfectant in water. We will integrate the decay kinetics into EPANet and carry out code verification. The key deliverable at the end of this project is the EPANet model containing agent degradation databases for simulants of one chemical and one biological agent.

Title:Geospatial Exploitation of Motion Imagery
Abstract:Motion imagery is emerging as a major source for intelligence information, especially in rapidly evolving tactical deployments. Novel deployment techniques, e.g. video sensors onboard unmanned aerial vehicles, distributed sensor networks, and handheld and fixed position monitoring systems are supporting the collection of timely, geospatially-registered information, enabling the precise monitoring of time dependent activity. The transition from static to motion imagery introduces significant challenges - indexing and retrieving large amounts of data, and extracting spatiotemporal activity patterns. Here, we present an innovative spatiotemporal helix approach to deriving temporal geospatial information from motion imagery. We present our approach for the scenario of identifying and labeling of object trajectories, and discuss its generalization to other geospatial information. In contrast to earlier work, our approach is applicable to arbitrary motion trajectories, and leverages metadata imbedded in the motion imagery stream for robust recognition. Our approach is fairly robust to incomplete and noisy data as our representation performs spatiotemporal smoothing, and filtering operations. We also propose to develop uncertainty management extensions to provide motion imagery time and position error budgets. Our Phase I research will show the enhancements and expansions to existing motion imagery capabilities in Army topographic terrain units, military intelligence units, and NIMA.

Abstract:Triton Systems proposes to develop novel dendrimers for detection and neutralization of biological warfare agents that can be easily incorporated into materials currently used as liners or filters in HVAC systems. Triton's approach will be to incorporate functional moieties on the periphery of PAMAM dendrimers that can "capture" and "neutralize" biological warfare agents. Using this method, the detecting agents and the passivating agents can be effectively immobilized in ultra-thin films that can be fabricated directly onto filter/liner substrates.

Title:AmmoSIM
Abstract:Compared to fighting in the open field, military operations in urban terrain (i.e., man-made, built-up areas) is the greater challenge. It is riskier and costlier in manpower, resources, and time. The urban environment easily provides the in-place enemy with settings for ambush, places to hide, civilians as shields for unscrupulous use, and many escape routes - above and below ground. Warfighting in cities adds so many challenges that most commanders would prefer to bypass population centers. How can we give our soldiers the advantage to this urban warfare challenge? In a word, information. 21st Century Systems, Inc (21CSI) sees an opportunity to provide the urban commander critical information using a weapon selection decision aiding tool during military tactical operations. The tool, entitled "AmmoSIM," will be used during action in the streets of the urban area. As the name implies, it simulates the direct employment and secondary effects of a specified set of weapon system components against a given target and the target environment. The tool would be used in conjunction with other terrain analysis systems and will provide two useful modes - single shot and barrage. This SBIR will culminate in an agent-based urban weapon-pairing management tool called AmmoSIM: a unique product.

Title:Optical Measurement of Penetration Resistance, and Automatic Determination of Rating Cone Index
Abstract:The Department of Defense currently administers 25 million acres of land. To expedite and reliably estimate mission impacts on this huge territory, the U.S. Army Corps of Engineers is soliciting an innovative portable device for estimating site condition in terms of Erosion Potential/Training Capacity/Trafficability (EPTCT). All current methods are based on manual collection of cone penetrometer data, which is neither automatic nor rapid. To eliminate this bottleneck, Physical Optics Corporation (POC) proposes to develop a novel device for optical measurement of penetration resistance (OMOPR) for automatic determination of the rating cone index in off-road soil. This device, to be installed on any driven wheeled vehicle, will measure wheel tire track depth and correlate the results with cone penetrometer data. The proposed OMOPR functions automatically to continuously generate rated cone index values for site EPTCT estimation. A minimal amount of cone penetrometer data will be required for system calibration, and the depth of a tire track will be measured optically by a system of laser triangulation sensors. In Phase I, POC will provide a feasibility demonstration of the OMOPR technology. In Phase II, a full-scale OMOPR system will be developed and tested under field conditions.

Title:Void Detection and Stiffness Measurement System for Road and Airfield Pavements
Abstract:Currently, people use man-operated heavyweight deflectometer to detect the void under runway and use large cone penetrometer to measure the soil stiffness. It is expensive, slow, and destructive. During the wartime, the operator will involve the risk from enemy­_s land mine, sniper, and artillery attacks. In this proposal, a very innovative remote void detection and runway condition survey system using a small robot is designed. The robot will integrate GPS navigation, motion control, visible and infrared stereo sensor fusion camera, ground penetration Radar, obstacle avoidance laser scanner, actuator-activated cone penetrometer, and digital modem 7 sensors to survey the runway with a speed of 5 miles per hour. The detection and measurement methods are quick, quite, safe, accurate, quantitative, automatic, non-destructive or minor-destructive, and without human involvement. The measured data will be wirelessly sent to the powerful computer at the remote control center for further processing and get correct conclusion. The measured stiffness will be used to: 1) locate areas with potentially hazardous voids, 2) identify weak sections of pavement that would pose a high risk for catastrophic failures, and 3) aide in the determination of the pavement load carrying capability. Although the Army does not request a prototype delivery or demonstration in phase-I, based on our rich experience in the phase-I research for SOF (we will enter phase-II soon), we have confidence to build and deliver the above survey robot and its 7 integrated sensors to the Army. A field demonstration at any site selected by the Army will be performed.

Title:High Temperature Matrices for Filament Wound Composites
Abstract:The Army desires to have a high temperature matrix for use in filament winding composites that can be easily processed at room temperature and has a minimum glass transition temperature of 260C (500F)when cured. This objective will be accomplished by developing epoxy curing agent technology based on eutectic aromatic amine and anhydride chemistries. Eutectics are defined here as combinations of solid or solid/liquid amines or anhydrides that when properly combined become a stable liquid at room temperture and may even possess lower viscosity than either component alone. The use of specific high temperature aromatic amines and anhydrides will be combined and the eutectic nature determined. These eutectics, in combination with multifunctional epoxy resins, can achieve the required processing and high temperature performance necessary for missle and rocket composite applications. API will focus only on epoxy technology due to the knowledgebase, fiber adhesion, low cure shrinkage, easy processing, and low cost in comparison to other high temperature resins, such as: BMI,cynate esters,phthalonitriles, and imides.

Title:High Temperature Matrices for Filament Wound Composites
Abstract:Despite the extensive research expended on developing high Tg resins for composite filament winding applications, these resins require heated processing which limits their general acceptance in current production facilities. Novel filament winding matrix resins are therefore proposed to overcome this limitation. TRI/Austin will develop a new class of hybrid resins that will offer the desired combination of high Tg and low viscosity. In addition, a mechanism will be investigated whereby a thermal barrier skin effect will protect the composite from extreme temperatures. This may be relevant in terms of eliminating the secondary thermal barrier coating that is sometimes necessary on rocket motor casings. Additional low viscosity high Tg candidate resins will be identified and used for comparison to the hybrid resin systems developed. TRI/Austin's team for the Phase I effort will include experts in the field of rocket motor filament winding technologies. These experts include personnel from a prominent rocket motor manufacturer that has been in business for over 50 years and has extensive experience in solid propellant rocket and gas generator development and production. Processing and performance requirements will be identified to ensure that the developed matrix resins comply with the end-use and manufacturing requirements.

Title:Robust Alignment Concepts for Precision Guided Weapons
Abstract:NETFIRES is a very sophisticated future ground launched missile. It is to be deployed in a sometimes unattended pod, and intended to be launched and controlled through AFATDS. While the individual missiles have their own navigation system, it may be desirable to know the orientation and location of the launch condition. These are classic artillery and mortar questions, significantly different from the dynamic transfer alignment problem alluded to in the topic description. The vertical axis is easy using gravity, but unfortunately, azimuth is much more difficult. Our best clues are limited to 1) earth rate 2) earth magnetic field 3) celestial bodies or other landmarks and 4) GPS attitude. In this project we will explore the tradeoffs of each. If there is an opportunity to transfer an azimuth reference from another electronic source, this will also be considered.

Abstract:RDAS will baseline its effort from a generic system, the elements of which could be either collocated or non-collocated, wherein the targeting sensor, weapon and fire control systems are integrated, as is the case for modern system development. From the baseline, the sub-elements of the system will be defined and the error sources identified. The errors will then be categorized as fixed, variable or random and then characterized. Concepts for determining misalignment will then be generated. At the conclusion of Phase 1, and in preparation for Phase 2, RDAS will propose for a Phase 1 option to develop the methodology and the criteria needed to select the best concept of those concepts formulated in Phase 1.

Title:Cost-Effective Fabrication of Transparent Spinel Domes
Abstract:Sapphire is the state of the art material for windows and domes with requirements for transparency from the visible to the mid-wavelength infrared (MWIR) region, where environmental loading is an issue. Unfortunately, sapphire is expensive and costly to fabricate due to its an-isotropic properties. Spinel combines superior MWIR transparency with isotropic properties. Consequently, it can be formed into near net shapes, and fabricated at lower costs than sapphire. The combination of improved transparency with potential for lower cost, make spinel an attractive candidate for high volume applications such as the Common Mode Missile. However, there has never been a reliable supply of optical Spinel material. One reason for this is the lack of reliable supply of Spinel powder. In Phase I Surmet will modify commercially available powder as well as synthesize its own powder. This powder will then be consolidated and heat treated to full density. Surmet's spinel process will combine the best practices of its production ALON process with lessons learned during their ongoing spinel development effort with a customer. At the end of the Phase I program, optically transparent 6" hemispherical spinel domes will be delivered to the Army for further testing and performance evaluation, to be followed by program review and Phase II consideration.

Title: Enhanced Spinel Domes
Abstract:The common missile is being developed for operation from a wide range of air, sea and ground platforms. Predicted production costs are driving much of the development direction at this time and spinel is the only durable, dual-band, electro-optical dome material capable of meeting these cost goals. Production approaches are therefore being pursued to establish a robust, low-cost fabrication technology to deliver spinel domes with excellent optical properties that require minimal finishing. This will be achieved by pressureless sintering near net-shape green spinel domes and careful ceramic processing. This proposal outlines the key technical hurdles to the success of this technology clearly identifying an approach to achieve technical readiness.

Title:Weapon Weight Reduction Using Genetic Algorithms
Abstract:The proposed project focuses on the development for an integrated system for structural optimization of weapon system components. The system provides an integrated process for topology optimization, geometry (shape) optimization, and sizing optimization. The software is designed to use 2-D and 3-D finite element solutions from off-the-shelf FEM solvers such as NASTRAN and ABAQUS or an internal FEM solver. Design constraints supported during the optimization process include compliance (stiffness), stress, buckling, and thermal (heat transfer) requirements. In order to reduce development risks, the software will be developed by integrating existing software packages wherever possible. This includes: (1) An off-the-shelf geometry modeling package that provides CAD import/export capabilities, (2) Two optimization packages that provide user-selectable optimization techniques (genetic algorithms and gradient based methods), (3) A FEM mesh generation package, (4) A cross-platform graphical user interface package, and (5) A distributed parallel computing package allowing concurrent execution of numerous trial solutions. The use of a scripting language to integrate the various software components results in a cross-platform application with a built-in scripting interface and API.

The software will have the capability of automatic mesh adaptation and parallel processing. It will evaluate different design alternatives using external finite element solvers such as ABAQUS and NASTRAN through Application Programming Interfaces (APIs). Apart from ensuring the cross-platform suitability of the software, special emphasis will be placed on minimizing user intervention after initial problem set-up. Under a potential Phase II program, we will implement of the software design, and demonstrate its capability and effectiveness. The planned effort complements the current research work being done at NextGen and Purdue University. To ensure near-term technology transfer, NextGen Aeronautics plan to coordinate the Phase I efforts with major aerospace and automotive companies, and include them on the team on a Phase II program.

Title:Rocket Exhaust Plume Secondary Smoke Formation Modeling
Abstract:Our proposal addresses the inclusion of a secondary smoke model into a modern CFD code that is widely used for plume simulations. This will permit high fidelity simulations of dynamic, missile exhaust plume flowfields that, under certain conditions, produce a condensation cloud that can obscure the electromagnetic signals utilized for guidance and targeting. We will utilize a state of the art Navier-Stokes code that already contains much of the requisite physics (finite-rate chemistry, multiphase particulates, condensation/vaporization, etc.) in a dynamic grid framework that was developed to analyze extended plumes (launch to target) for tactical systems. In Phase I, we will implement and demonstrate the operation of an advanced secondary smoke model in the CRAFT CFDr code that will model the condensation of water vapor on heterogeneous nuclei in the presence of HCL. The resulting droplets will be composed of water only and droplets with variable water/acid compositions will be addressed in Phase II. We will assess the potential of the modeling approach for providing high fidelity predictions that can accurately simulate secondary smoke formation in tactical missile exhaust plumes under a broad range of conditions, and in our optional task, perform studies for a representative tactical missile system.

Title:Nanocomposite Processing for Multimode Radome Applications
Abstract:Improvement in deployed missile system capabilities has been one of the essential missions for U.S. Defense. Next generation missile systems will require multi-mode seekers to improve standoff distance, provide all weather capability, and allow for some degree of target recognition or aim point selection. Therefore, there is a need for developing an advanced material for tri-mode RF seekers. Utilizing these technologies requires radomes that are compatible with IR, RF, and millimeter wavelengths. This program proposes an innovative method of processing nanocomposite powders to achieve a fully dense nanocomposite, which can be fully transparent from 1 to 7 microns. The program will investigate the effects of particle size and the heat treatment on the final structure and IR transparency. During the Phase I program, hot-pressing will be performed and pressureless sintering will be performed during the Phase II program. By combining the IR transparency and low dielectric properties, the material developed from this program can be compatible with IR, RF, and millimeter wavelengths and can survive the thermal-structural environment.

Title:Nanograin MgF2 for Multi-Mode Seeker Dome
Abstract:Next generation missiles require multi-mode seekers that combine both infrared and millimeter wave capabilities to improve standoff distances and allow for accurate target recognition. Materials used to fabricate domes for such seekers suffer from drawbacks such as high dielectric constant and/or inferior transparency to IR. Magnesium fluoride is a candidate material for the above application since it is known to possess superior dielectric and IR transmission properties than other traditional dome materials. Despite the established promise of this material, it has not yet been successfully used, due to its inferior mechanical properties. In this Phase I Small Business Innovation Research project, Materials Modification Inc., aims to overcome the above drawback of MgF2 by fabricating nanostructured material that will exhibit good mechanical and optical properties. MgF2 nanopowders will be prepared by a proprietary process and will be compacted to high-strength, optically transparent pieces for fabrication of multi-mode seeker missile domes. Phase I will involve processing of the nanoparticles and their consolidation into near net shapes while Phase II will include scaling up the process for producing, in addition to domes, a large number of parts for use by defense organizations.

Title:Particulate Impact/Erosion Phenomena and Materials Failure for Supersonic KVs
Abstract:The development of missile technology and missile systems will benefit greatly from a capability to simulate the dynamic particulate aerodynamic environment that a supersonic missile experiences during flight. Such a capability will provide the systems design engineer the ability to assess the mechanical and optical performance of the targeting system in a solid or liquid particle environment and determine whether or not the window will fail or to what extent the missile's ability to kill the target is degraded. Currently this capability does not exist. Systems developers must rely on costly and time consuming testing that in all but a few examples do not meet the requirements or rigors of the particulate environment. This effort develop a capability to incorporate into the ATAC3D code a particulate model that can model the impact environment, statistically quantify the number of impacts, the size distribution of the impacts, the level of damage experienced by the window, probability of failure, and optical performance.

Title:Performance Assessment of Carbon Nanotube Containing Coatings and Sealants
Abstract:Electromagnetic interference (EMI) has become a major concern in military applications, as EMI interference reduces the lifetime and efficiency of instrumentation and telecommunication equipment. Luna Innovations, in this Army Phase I SBIR, will assess the effectiveness of single walled carbon nanotube (SWCNT) additives in enhancing the EMI shielding of current military paints and coatings, while preserving or improving other coating characteristics (for example, corrosion resistance and durability). Single wall carbon nanotubes are prepared at Luna Innovations (nanomaterials division) and numerous other sources, and have properties and aspect ratios greatly influenced by the mode of preparation. In Phase I, Luna will evaluate various admixtures of single walled carbon nanotubes (functionalized and unfunctionalized) and current military coatings with respect to EMI shielding, durability, corrosion and chemical agent resistance. Carbon nanotubes of varying aspect ratios will be used, until the most promising formulations are identified for further research and commercial development. A detailed cost analysis will be completed in Phase II. Luna Innovations has assembled a dynamic team combining expertise in nanotube synthesis and functionalization/solubilization techniques, electrical engineering, corrosion science, a military coatings supplier and expert, and business/marketing specialists to ensure a successful program and transition to Phase II/Phase III optimization and commercialization.

Title:A Novel Self-sensing Local/Global Structural Health Monitoring System
Abstract:The objective of this proposed project is to develop dual E/M impedance and wave propagation based innovative structural health monitoring (SHM) system for application to composite structures for Army rotorcraft and unmanned air vehicle platforms. Composites can incur invisible damage from impacts, loading abrasion, operator abuse, or neglect that if unchecked may lead to lower structural reliability, higher life-cycle costs, and loss in operational capability. This situation can be rectified by the use of a built-in inspection system that can monitor structures in real-time thereby providing for inspection and damage detection with minimal labor involvement. Acellent proposes the development of a stand-alone sensory array system containing the capabilities for local and global structural area damage detection, data evaluation, wireless data transmission and data storage and processing. The system will be developed based on Acellent's SMART Layer Technology that utilizes a built-in network of piezoelectric transducers embedded on a thin dielectric carrier film that queries, monitors and evaluates the condition of a structure. Phase I will focus on demonstrating the feasibility of development of a dual methodology E/M impedance and wave propagation system using an embedded sensor network. Architecture requirements for a diagnostic/prognostic SHM system will also be developed in conjunction.

Abstract:Utilizing newly developed solid propulsion technology developed at ET MATERIALS LLC a throttable controlled solid rocket motor will be develoed that incoporates variable thrust control without moving parts or varying the nozzle area. A dual mode grain incoporating ET MATERIALS controllable extiguishable solid propellant will be used to vary the pressure in the chamber containing a conventional AN high slope propellant. Various models will be studied to establish a thrust throttable range of 15:1 and determine the capability to provide for extiguishmens and reignition of the propellant grains. In addition, the capability of the controlled solid propellant to provide thrust control during the trnansient ignition phase will be established, thus providing for total thrush control management of the motor.

Title:A Throttling Solid Propellant Rocket Motor with Adaptive Thrust Control
Abstract:An innovative nozzle concept is proposed to enable variable thrust solid rocket motors to operate with minimal loss in efficiency over a wide thrust range. The proposed approach will also allow commanded near-extinguishment of the motor, and more controllable start transients. The approach will be compatiable with an adaptive control system to allow closer adherence to a specified mission profile. A Phase I program is proposed which will evaluate the concept using CFD analysis and produce an optimized approach for a development test program to be conducted in Phase II. Pintle design concepts have been applied in the past with limited success. The proposed design addresses the problem areas identified in previous solid motor variable thrust programs. By applying technologies used in other applications, the Phase I objective will be to determine the feasibility of variable thrust solid motor operations with higher performance throughout the thrust range by providing convincing evidence that the technical issues can be resolved. Phase II will demonstrate the feasibility by conducting component and engine testing, final design, and prototyping of a development system suitable for production design culminating in a demonstration test of the development hardware.

Title:A Throttling Solid Propellant Rocket Motor with Adaptive Thrust Control
Abstract:This proposal outlines a Phase I SBIR program to define and develop a throttling solid propellant rocket motor with enhanced performance capability and minimum 15:1 turndown that provides total thrust management capability for tactical missile applications thru adaptive control and propellant extinguishment (also non-extinguishment) techniques. The adaptive control techniques to be used will interface with a variable area nozzle system to provide closed-loop control system capability with the built-in intelligence necessary to provide on-demand thrust control to the missile. Active optimal thrust control during the important ignition transient phase will be fully implemented and the overall delivered performance of the pintle motor will be maximized to the greatest extent possible. Many propellant formulations obtained from three different propulsion companies will be evaluated to ascertain the candidate providing the greatest overall motor performance capability. Insensitive munitions, aging, smoke and other important propellant performance parameters will be ranked and scored to determine this BEST available propellant candidate. As a result of PRI''s present state of pintle motor development in several key program focus areas, the Phase II program will be able to concentrate exclusively on hardware development and pintle motor testing. In addition to testing at propulsion companies, pintle motor testing at support contractor operated Government testing facilities will also be proposed with Sponsor approval.

Title:High Speed X-Band Single Pole 4 Throw Switch
Abstract:This solicitation calls for the investigation and development of a specialized high performance X-band Single Pole 4 Throw (SP4T) microwave switch. This switch will be used in used at the US Army AMCOM's Hardware-in-the-Loop (HWIL) facilities. The currently used PIN switch technology has rise and fall times on the order of 200 nS, as the goal is to switch at a rate of 60 MHz switching speeds on the order of 3 nS are required. In conjunction with demanding insertion loss and isolation requirements the specification is extremely challenging. This proposal presents the methodology to be used during Phase I to develop the optimal switch. Simulations presented in the proposal include insertion loss, isolation, switching speed, video feed through and various transient simulations. In this proposal we describe several technological alternatives to PIN technology for fast switching the most promising candidates including MESFET, PHEMT and MHEMT technologies. These technologies are all depletion mode FET based technologies and while their cut-off frequency is considerably lower than that of PIN technologies their switching speed is superior. The three terminal structure of the FET devices and the fact that they do not require a DC current to sustain their ON state makes biasing them simpler in comparison to PIN devices. The Phase I option will be used to develop the interface and packaging concepts required to achieve the isolation and interface goals for the SP4T.

Title:Active RF Switch Array (9646)
Abstract:Q-DOT proposes to develop an Active RF Switch Array for the Army's hardware-in-the-loop (HWIL) missile seeker test system. The switch array is designed to route 10 GHz X-band signals at low levels of approximately 0 dBm. IBM's SiGe heterojunction bipolar transistor (HBT) technology is used to create ultra-fast active RF switches capable of switching times of 200 ps or less. This integrated circuit technology may also be capable of integrating other functions such as gain and signal combining in order to produce a complete 4 x 4 or 4 x 8 switch matrix on a chip. The active switch approach has the potential to provide ultra-fast switching with constant port impedances while reducing the size and component count of the switch matrix. Under Phase I, Q-DOT will perform an architecture study and circuit approach evaluation to determine the feasibility of the switch array and the more complex switch matrix. A prototype switch array will be built and tested in Phase II.

Title:Compact, Efficient, and Robust Eyesafe Ladar Transmitter
Abstract:The Army has identified a need for a laser transmitter for the NetFires Loitering Attack Missile and Precision Attack Missile programs, and for similar ladar systems in expendable munitions. CTI has performed a detailed trade study which shows that current 1 or 1.5 micron laser architectures (based on bulk Ho, Er and Tm lasers, OPOs/OPAs and Raman lasers) are poorly-matched to Army requirements for transmitter cost, efficiency, footprint and performance ( 5-10W, 20-30kHz, 5-20ns, 0.3-1.0 mJ). Single-mode or large-mode-area double-clad fiber lasers are attractive for efficiency, cost and packaging, but the peak power levels required for Netfires are too close to limits set by damage and parasitic nonlinear processes. Our trade study, conducted to meet Army efficiency and packaging goals, has led us to a novel patent-pending fiber-based laser architecture that retains the advantages of single mode fiber, but enables robust scaling to peak power levels required for the Army application. The architecture provides a clear path to a simple, compact and robust system with low parts count and high wallplug efficiency. A preliminary concept for the rugged prototype transmitter has been developed, leveraging off CTI's widespread experience with rugged flight-qualified laser systems and mature optical telecom components at 1.5mm, as well as recent demonstrations and parallel programs. Phase I will conduct validation demonstrations of the ladar transmitter and develop a preliminary design for the prototype transmitter. Phase II will develop and test the prototype, and deliver it to the Army for testing.

Title:Mixed-Effects Logistic Regression Model for Missile Reliability Prediction
Abstract:In this Phase I SBIR project we propose to use a Linear Mixed Effects Logistic Regression Model for missile reliability assessment. An effective model candidate for missile reliability assessment must be flexible enough to incorporate the different nature of covariates, yet simple enough to allow practical methods for parameter estimation using a realistic amount of sample data. A Logistic Regression Model is particularly suitable for modeling dichotomous data such as pass/fail in missile tests. The main advantage of a Mixed-Effects Model is that it provides a systematic method of aggregating a large numbers of effects of different nature into a manageable number of random effect terms in the model. This in turn allows us to estimate the model parameters efficiently. By combining the desirable features of these two models, we expect the proposed model will perform favorably compared to standard linear regression models. During this Phase I project we will obtain test data, determine the appropriate model structure and estimate the model parameters, and evaluate the model prediction performance to demonstrate the feasibility of the proposed model. We will also investigate the use of the Expectation-Maximization algorithm to cope with the issue of incomplete covariates data. Dr. Alyson Wilson and Dr. Nicholas Hengartner from Los Alamos Lab will provide consulting support on the choice of model structure and covariates, and parameter estimation issues during the Phase I period.

Title:Novel Fuel Gel Formulations and Methods for Property Optimization
Abstract:Gelled propellants are safer to handle, have reduced flammability and lower spill susceptibility compared to traditional liquid fuels. However, they are more difficult to atomize and combust, and the gelling agent can cause a loss of specific impulse. EERGC Corporation in cooperation with subcontractor NGST, a leader in gel propellant technology, proposes to develop MMH-based advanced fuel gels that provide higher volumetric specific impulse, incorporate combustible particulate gellants, and have established spray characteristics. To do this we will optimize the physical and chemical characteristics that determine the suitability of gels, including quantitative measures of: 1) The affinity of the components with one another, which affects fluid separation; 2) Physical properties, including surface tension and viscosity, which affect flow and atomization; 3) Chemical properties including energetic content which affects the specific impulse, and the resulting combustion products, which affect the plume emissions signature; 4) Evolution of gaseous products by physical or chemical means, which affects the long-term storage of the gels. This is a departure and advancement over prior work, quantitatively addressing significant issues not previously addressed, particularly the impact of interfacial interactions on heterogeneous gel ingredient interactions and on the surface tension properties and breakup behavior of the gel.

Title:Advanced MMH-Based Gel Fuel
Abstract:ORBITEC and SRI propose to develop an advanced gel propellant fuel based on monomethyl hydrazine (MMH) that provides higher volumetric specific impulse, incorporates a combustible particulate gellant, and has desirable stability and aging characteristics. To improve volumetric Isp, a performance-enhancing compound can be added in conjunction with existing polymeric gelling agents, or new high-energy gellants can be used. Various solid-fuel additives will be considered to provide additional performance benefits by increasing density specific impulse. Atomization can be improved by adding surfactants to modify the MMH surface tension. The resulting MMH-based gel fuel is expected to meet the demands of at least 25 lbf-s/in3 increase in volumetric specific impulse, minimum exhaust signature, high stability, and long life required for advanced propellant gels.

Title:Skeletal Muscle Water Content Measurement Sensor/Tool
Abstract:The objective of this proposal is to develop a Muscle Water Content (MWC) sensor, an ultrasonic device for assessment of body hydration status in soldiers with accuracy better than 2% during deployment and training. The MWC assessment is based on measurement of ultrasound velocity in muscle, which is, to a good approximation, a linear function of the water content. The expected outcome will be a lightweight, compact, and simple sensor for military use as well as civilian medical use for assessment of hydration status of various institutionalized patient, athlete, and worker populations. The proposed ultrasonic sensor will advantageously differ from the existing techniques by its completely non-invasive application, higher accuracy, rapid tests and possibility of continuous monitoring MWC by a portable lightweight device in the field. The goals of Phase I and Option Effort are to build the first MWC sensor prototype and to demonstrate the feasibility of the proposed technology and necessary sensitivity in the experiments on tissue models and ex vivo animal muscles.

Title:UWB Muscle Water Content Sensor
Abstract:During this Phase I, we intend to evaluate Ultra Wide Band (UWB) radar for use as a sensor for water content of skeletal muscle. The sensing mechanism is based on the large difference between the dielectric constant of water, and that of the host material. We have clearly demonstrated the feasibility of this approach for sensing of moisture in materials with gross dielectric properties similar to invitro muscle tissue. The sensor will be capable of generating two- and possibly three-dimensional images of water content of skeletal muscle. The sensor will be non-contact. The basic hardware (UWB chip set) is being developed for the communications market, where economies of scale will sharply drive down prices. This will allow for the development of a novel, cheap, and accurate non-contact Total Body Water (TBW) sensor. Because our hardware emits ultra-low power RF signals (45microwatt, as compared to about 2 Watt for a cellphone), there is no risk to human subjects to be subjected to the sensor.

Title:Proteomic Biomarker Diagnostics for Early Detection of Cancer using MEMS Biosensor Arrays
Abstract:BioScale is developing a high-throughput diagnostic tool to perform proteomic assays of multiple protein biomarkers for early detection of cancer and infectious disease. Genomic and proteomic profiling of tumors and cancer cells are enabling the new paradigm of "Proteomic Diagnostics", namely the measurement of multiple biomarkers matching the proteomic profile of specific disease states. Such tests promise to achieve the ideal of >96% sensitivity and specificity. Elucidation of specific proteomic profiles of cytokines released in response to infectious disease offers another such opportunity. Rapid and specific measurement of multiple proteins in the serum proteome can be enabled by instruments based on arrays of non-fouling biosensors capable of sensitive and quantitative detection. This Phase I proposal will demonstrate such detection capabilities in a non-optical MEMS sensor array by integrating a candidate set of biomarker assays aimed at early detection of prostate cancer. Phases II and III of this effort will focus on further clinical screening of sets of proteomic biomarkers and the development of the sensor array platform into a rapid diagnostic tool for clinical labs. Such a proteomic profile assay system will accurately detect specific disease states in individuals facilitating effective screening and therapeutic decision-making in military and civilian settings.

The system will perform label-free quantitative detection of the activity of the members of the family of metalloproteinases in unpurified extracts of tissue or body fluid. The MIRPA system will contribute to early and accurate diagnosis of cancer and increase caregivers' ability to adapt to a tumor's changing phenotype as a particular therapy progresses. This technology will also be very useful for generating infectious disease profiles and profiles characterizing exposure to biological and chemical warfare agents. In Phase I, POC will design and fabricate a MIRPA model and demonstrate the proof-of-concept. Phase II will culminate in a prototype that will successfully distinguish between normal and cancerous/diseased tissue using well-characterized controls as well as clinical and pathological findings.

Title:Personal Area Network for Warfighter Physiological Status Monitoring (WPSM)
Abstract:We describe an effort to design and implement a reliable, secure, medium-bandwidth wireless personal area network (WPAN) that supports routine, continuous ambulatory physiological status monitoring of physically active warfighters. This proposal primarily addresses the development of a Warfighter Physiological Monitoring System, or WPSM, wireless sensor PAN. The WPAN supports the WPSM mission of continuous physiological data acquisition and real-time health, performance, and injury classification. Enabled by the WPAN, the WPSM comprises a light-weight, robust, self-contained body-worn, or "wearable," system for monitoring such physiological parameters as heat, hydration, fatigue, and injury, Further, the WPAN enables the WPSM to provide early-warning indicators of exposure to biological/chemical weapons and pathogens. Finally, the WPAN enables the WPSM to enhance individual performance, improve planning and team-level situational awareness, and improve combat casualty care. The WPAN would be useful in general commercial environments, where team members collaborate and cooperate to accomplish a task. Furthermore, the WPAN would be useful in hazardous environments, where safety workers must operate to aid others in peril.

Title:Respiratory Endothelial Cell Sensor for Real-Time Air Toxicity Monitoring
Abstract:Because endothelial cells organize to form a tight barrier under normal conditions, several electrical devices have been used to measure the electrical resistance of endothelial cell monolayers. An Electric Cell-substrate Impedance Sensing (ECIS) system can measure the electrical impedance of endothelial cell monolayers on gold electrodes in real-time. This system is extremely sensitive to any changes in the integrity of the endothelial cell barrier and therefore would make an ideal biosensor to detect changes in endothelial cell "health" after exposure to a broad range of chemical and biological warfare agents. Although this device has been used for several years to assess endothelial cell monolayer integrity after exposure to a variety of agents, to date this system has not been exploited for development as an airborne toxin biosensor. We believe such a novel system could be developed by integrating current ECIS systems with respiratory endothelial cells, microfluidics, and air sampling technology. In this Phase I, Agave BioSystems proposes to adapt ECIS technology for detection of airborne chemical and biological agents using respiratory endothelial cells as a broad and highly sensitive detector, state-of the art air samplers for monitoring the environment, and microfluidic technology for continuous delivery of samples to the biosensor.

Title:Honey Bee Fast Response System for Broad Band Detection of Airborne Toxicants.
Abstract:This Small Business Innovative Research Phase I project is to develop a broad band detection system for air toxicity. Our overall objective is to show that honey bee orientation and locomotor behaviors can be used as reliable and measurable indicators of certain airborne toxicants. Locomotor sufficiency and directional orientation are behaviors that should unambiguously indicate toxicant exposure. Nearly all airborne toxicants affect the sensory systems or neuromuscular coordination of honey bees, either through cuticular absorption or inhalation,. Above threshold exposures, neurological and motor impairment should progressively degrade efficiency of movement of bees toward a goal. The resulting application builds upon our proven bee colony real-time monitoring and data delivery system. The proposed project introduces new features to: (1) demonstrate that honey bee orientation and movement at the hive exhibit unique responses upon exposure to airborne toxicants, (2) quantify dose-response relationships to the tested toxicant, (3) determine lower threshold concentrations for measurable response; (4) determine whether other environmental perturbations could elicit a similar behavioral response, and (4) demonstrate that a bee colony will display measurable responses across a range of exposures in less than 30 minutes, over a two week demonstration period. These studies will facilitate construction of semi-quantitative response profiles for a hazard evaluation system, and for benchmarking bee responses to existing human exposure risk data, resulting in a report on the efficacy of using bee behaviors to monitor health hazards from airborne toxicants, as well as a plan for a hive-mounted device that can be incorporated into our existing real-time monitoring/reporting systems, leading to Phase II application, and Phase III activities and self-sufficiency.

Title:Integrated Architecture for Functional Genomic Measurements
Abstract:The integrated informatics architecture proposed here will facilitate the construction of gene regulatory and other biological pathway models from networks of molecular and phenotypic associations. Current commercial or academic solutions are mostly limited to basic analysis of array data to determine differential expression and do not practically address the advanced analysis of array data to uncover sets of regulatory associations between genes. Moreover, no commercial solutions exist to assist scientists in the critically important task of taking the results of these advanced analyses and assembling testable models from them. The work proposed here will create a next generation informatics architecture that overcomes these deficiencies by providing (1) advanced analytical methods to identify from either Affymetrix or De Novo spotted RNA array data networks of regulatory associations between genes and (2) methods to assist in the interpretation of function genomic results by providing methods to build gene-phenotype association models about which, how and where molecules associate with one another and what are the molecular and phenotypic effects of the association. The components of the architecture will be able with freely exchange information with biological databases, literature mining, analysis and visualization applications to allow better interpretation of the resulting analyses and models.

Abstract:An innovative technique is needed to simulate the "look and feel" of open surgery. Current techniques are inadequate for training and measuring surgical skill. Visual feedback is especially important for open surgery, with haptic feedback secondary. Energid Technologies proposes developing an open surgery training system that uses our method of video-based tool tracking. Our approach will unintrusively capture the motions of the surgeon and accurately render the visual scene. This will allow the surgeon to use normal, untethered instruments. This will be combined with optional, untethered magnetic haptic feedback that is made possible through the video-based tool tracking. These techniques will be combined with surgical-skill metrics and training feedback to provide a complete training system. Our archetype procedure will be open splenectomy in a case of splenic trauma.

Title:Haptics-Optional Surgical Training System (HOSTS)
Abstract:Surgical simulation has a widely recognized potential to improve the training of surgeons, yet faces many technical and market challenges. A simulation system based on an adaptation of the da Vinci surgical system already owned by the Army at Walter Reed, capable of open as well as minimally invasive surgery simulation, and developed by Intuitive Surgical, a potential user of simulation technology (not just a promoter) would address many of these challenges. Because the da Vinci system was designed to emulate open surgery, the da Vinci master has all the degrees of freedom necessary for an open surgery simulator. Intuitive will leverage synergies with millions of dollars of past R&D investment, hundreds of person-years of prior work, and a collaboration with SimSurgery AS to produce a demonstration simulator coupled with the da Vinci surgeon's console by the end of the Phase I. Intuitive will use its unique combined role as a medical device company using simulation to meet training requirements as well as a technology provider to pull simulation technology through to its surgeon customers and cut a path for other simulation applications to gain entry into hospitals.

Title:Haptics-Optional Surgical Training System (HOSTS)
Abstract:In summary, we propose to plan a prototype Basic Surgical Trainer as part of a standardized basic surgery training curriculum, which we will develop with input from world leaders in surgical education. During Phase I, the trainer will focus on one surgical procedure, i.e., sebaceous cyst excision, and its subtasks that comprise key skills for surgical training. The subtasks will be evaluated to determine which ones need haptics for effective training, and to develop performance metrics to set an objective standard for skill acquisition. During the option period, we plan to complete a design document, and develop the curriculum and performance metrics. During Phase II, we plan to build the prototype and validate the curriculum and the simulator with respect to their efficacy in providing training that translates into excellence in the operating room. In addition, we plan to use surgical trainees in a transfer of training study and to evaluate the need for haptics as part of a simulator training device.

Title:Diagnostic Microarray Test Based on Comparative Studies of Gene Expression in Humans with Common Inflammatory and Infectious Diseases
Abstract:In order to assure accurate detection of exposure to biological warfare agents or any environmental agents, it is necessary to exclude a variety of common conditions that may confound proper diagnosis. Many groups, including ours , have found that biological warfare agents can stimulate inflammatory systems, the same systems found stimulated in common inflammatory disease such as rheumatoid arthritis, inflammatory bowel disease or ankylosing spondylitis. In order to create an accurate diagnostic tool, it is therefore necessary to define the changes in gene expression that are characteristic of these common inflammatory diseases in clinically accessible tissue (such as peripheral blood) and compare them with the genetic expression level changes characteristic of exposure to biological warfare agents. The database of genes that make this distinction most effectively will be used in the creation of a practical diagnostic test. The addition of the work proposed herein to our existing projects will result in complete expression databases for rheumatoid arthritis, inflammatory bowel disease, hepatitis C and ankylosing spondylitis. This will allow for the creation of a straightforward test reflecting only the gene expression changes indicative of exposure to particular biological warfare agents or existing inflammatory conditions

Title:Accelerated Drug Design Through Computational Biology
Abstract:Our initiative to design agents to combat Plasmodium falciparum, the most debilitating of several malaria strains, combines powerful bioinformatic techniques to develop protein target structures with a multifaceted strategy for rational drug design. Using the available x-ray crystal structure of CDK2 as a structural template, we will generate and validate three-dimensional structural models of the P. falciparum kinases using computer-based homology modeling techniques. These models, together with structures available for mammalian CDKs, will enable us to employ a battery of computer-assisted rational drug design techniques, including a proprietary tool called Shape Signatures, to accelerate the identification of drug candidates that not only are potent antimalarial agents but also selectively inhibit P. falciparum over human CDKs. The limited success of prior compounds examined under these criteria may be attributed to "off the shelf" testing rather than their rational design. This study will remedy this shortcoming by employing computer-assisted drug design approaches to exploit differences in key ligand-binding residues within Pfmrk versus mammalian CDKs. Our modeling study of PfPK5 is provided as proof-of-concept. This design strategy is further enhanced by our expertise in protein expression, assay development and execution such that lead validation provides rapid iterative feedback to the molecular design process.

Title:Accelerated Drug Design Through Computational Biology
Abstract:New computer-based modeling and data mining tools are continuously being developed to help assess and exploit targets uncovered in genomic research. Traditional computer-aided drug design software has several serious shortcomings. Cross-vendor incompatibilities induce users to use single software exclusively. The user's ability of `Mix & Match' software, unattainable with any current offering, has been shown to enhance in silico hits discovery and enrichments and to lead to increased hit rates. Additionally, low throughput of compute-intensive jobs in commercial seriously limits `Docking-scoring-hit identification' due to its inability to partition and streamline jobs execution across a cluster of compute servers. These limitations inspired TransTech Pharma to introduce innovations to circumvent them. The proposed system features a graphical user interface, `Mixing & Matching' cross-vendor software, uses a `divide-and-conquer' strategy to increase throughput across a multi-unit/multi operating system distributed processing architecture to parallelize job execution across a cluster of compute servers. This parallelization would maximize throughput of complex and compute-intensive computational chemistry tasks. The system will be validated using structure-activity information for three cyclin dependent kinase inhibitors - PfPK5, PfPK6, and Pfmrk as targets. Initial work showed that Pfmrk has 40% sequence identity to MAP-Kinase P38 whose crystal structure would serve as threading & homology model template for Pfmrk.

Title:Innovative Manufacturing Techniques for Polysaccharide-Protein Conjugate Vaccines
Abstract:This project develops a conjugate vaccine against Shigella flexneri 2a utilizing cGMP-compatible manufacturing processes. The antigenic component of the vaccine is deacylated-polysaccharide from the bacterial LPS that has an average of one O-antigen repeat unit per polysaccharide molecule. The polysaccharide is deacylated by a biological process, and has a core structure with intact phophosphoryl groups. It is expected that phosphorylated core components will elicit antibodies that cross-react with LPS of other strains and species of Shigella that share these core epitopes. Phase I research studies will provide a cGMP-compatible method for producing the conjugate vaccine, and Phase I Option studies will evaluate the immunogenicity of the vaccine, and its potential to elicit cross-reactive antibodies against several serotypes of S. flexneri and against other Shigella species.

Title:Anti-Microbial Nanoparticles Composed of a Magnetic Core and Covered with Photocatalytic TiO2
Abstract:Physical Sciences Inc. (PSI) proposes to utilize reverse micelles as constrained nanoreactors for controllably fabricating magnetically extractable, anti-microbial nanoparticles. A 20 nm diameter nanoparticle composed of a magnetite core surrounded by a titanium dioxide (anatase phase) shell will be the target of this Phase I. Critical to the success of this effort is the ability to control the micelle geometry and to minimize the processing temperature necessary for crystallization of the anatase layer. PSI intends to demonstrate the ability to control the diameter of the micelle's aqueous core, forming a cage-like structure, limiting the formation of the coating to a thin, uniform, conformal layer. After the coating layer is applied, temperatures in excess of 400 C are normally required to obtain the desired crystalline form and further densify the layer. These high temperatures can lead to defects in the structure through inter-diffusion, undesirable phase changes, and the generation of electron/hole recombination centers; potentially leading to both inefficient photoactivity and poor magnetic performance. In Phase I, PSI expects to demonstrate, using a simple metal salt, the formation of the anatase phase at temperatures as low as 150 C.

Title:Programmable Wrist-Worn Prediction Model and Environmental Stress Monitor
Abstract:In the next few years it will be possible to build a commercially viable wristwatch sized instrument suitable for Objective Force Warrior that contains environmental sensors, motion sensing, electronics, and algorithms to predict environmental stress, sleep, performance, and life signs. The complementary sciences have been extensively developed by their respective research agencies, but have not been integrated into in a single instrument. Continuous day and night time human activity modeling and environmentally driven thermodynamic algorithms provide the basis for a physiologic model that may predict metabolic expenditures, and indirectly estimate core temperature variability for specific activities. The proposed Programmable Wrist-Worn Environmental Stress Monitor will provide the wearer with estimates of stress and strain as defined, and overall fitness for duty throughout the day. The instrument will accomplish this by: 1) Measuring the daily ambient environment and estimating work rate, 2) Continuously estimating sleep and recording sleep history, 3) Applying stress/strain and performance algorithms, and displaying the results.

Title:Perioperative Readiness Information Management Environment
Abstract:Accurate patient information is perhaps the most important requirement for the delivery of safe, coordinated and comprehensive care by members of the health care system. This is especially true of the complex and high-risk perioperative process where the consequences of compromised patient safety can be severe. To help avoid errors, the entire team must share the same awareness of the situation and the information must be accessible at will in order to see trends and make predictions. There is a need for an integrated perioperative support system for delivering the best possible care to patients, thereby reducing errors and increasing patient safety. A human factors and risk analysis approach to identify safer clinical processes can inform the design of a perioperative information support system. To achieve this goal we will design and develop PRIME, a web-enabled, model-based Perioperative Readiness Information Management Environment. In the base period we will identify the normative model of information flow in the perioperative process and identify vulnerabilities in the network that would most benefit from a layer of decision support, and in the option period design the concept for the system.

Title:Patient Safety Perioperative Readiness Support System
Abstract:This Phase I Proposal aims to analyze current perioperative protocols and develop a plan for a fully integrated, patient-centered data acquisition system enabled by interactive PC-based devices. The study will include a detailed report on integration challenges present in current operating room procedures and logistics. Existing methods of obtaining patient information prior to and during surgery is redundant, inefficient and susceptible to errors. In this project, all areas of data acquisition involved in surgical procedures will be examined, from the operating room environment to hospital-wide IT systems. The solution to these present challenges will propose an innovative and unique solution of a single database that automatically records information to track the entire perioperative environment. This database will also provide an objective understanding of the nature and incidence of adverse events in operative rooms/surgical settings, and also effectively support the deployment and measurement of strategies to prevent such adverse events. LiveData, Inc. will be working directly with investigator from Massachusetts General Hospital to define, design and implement this product (in Phase I and Phase II). Long term, a complete hardware software solution will be built based on this studies finding.

Title:Polyphosphazene Presenters for the Mulitmeric Protein Malaria Vaccine
Abstract:There is a critical need for the development of malaria vaccine to protect military and civilian personnel. It has been demonstrated that the PfMSP1-42 protein, a leading vaccine candidate, might require presentation in a multimeric form to achieve the optimum efficiency. Parallel Solutions Inc. (PSI) proposes to develop water-soluble polyphosphazene based carriers for the effective multimerization of the PfMSP1-42 protein. PSI has previously shown that polyphosphazene polyelectrolytes can effectively bind protein molecules in multimeric non-covalent complexes, which demonstrated superior performance in vivo when compared with alum and other adjuvants. These interactions result from the conformational adjustability of the macromolecule, the diversity of attachable ligands and the high functional density and multimeric display. The lead candidate, PCPP, has demonstrated an excellent safety profile. PSI will screen already synthesized polyphosphazene compounds for the optimal binding characteristics and refine polymer structures as necessary. In Phase I, we will identify and develop polyphosphazene-PfMSP1-42 protein complexes capable of multimeric protein presentation without affecting the conformational epitopes.

Title:Isolation of Focal Adhesion Kinase-specific Modulators
Abstract:Focal Adhesion Kinase (FAK) plays an important role in transducing signals generated by cellular adhesion molecules regulating cellular migration, growth and survival. It is becoming clear that FAK also relays angiogenic signals from multiple cell surface proteins. Inhibition of FAK by expression of the noncatalytic carboxyl-terminal protein-binding domain of FAK, known as FRNK (FAK-related, non-kinase) reduces vascular endothelial growth factor (VEGF)- and vascular cell adhesion molecule (VCAM)-induced angiogenesis, as well as platelet-derived growth factor (PDGF)-induced proliferation and migration. Additionally, embryos of FAK-knockout mice demonstrate impaired blood vessel formation most likely due to migratory defects. Thus, FAK activity appears to be essential for angiogenesis. This emerging role for FAK suggests that a small-molecule inhibitor of FAK would disrupt angiogenic signaling. Additionally, the use of FRNK has demonstrated that FAK inhibition may enhance the cytotoxic effects of chemotherapeutic agents on transformed cells and inhibit proliferation of tumor cells. Thus, a small-molecule, FAK-specific inhibitor would have many applications. We have developed high throughput screening assays for identification of small-molecule, kinase-specific inhibitors. We will screen an extensive natural products library derived from plants of rare genera to isolate and identify FAK-specific inhibitors.

Title:Amplification of Proteins in Body Fluids for Early Detection of Biological Warfare Exposure
Abstract:This SBIR Phase I project will lead to the development of a technology to detect very low levels of multiple pathogen-specific proteins or human proteins very quickly after exposure to biological warfare (BW) agents. The technology will link several proven techniques in a unique sequence so that a mixture of biological warfare proteins can be accurately and sensitively detected in one simple procedure. First, we will generate high affinity rabbit monoclonal antibody (RabMAb) pairs for specific biomarkers, using our proprietary rabbit hybridoma technology. Second, we will develop a sensitive, multiplexed assay system that combines antibody binding, T7 RNA polymerase amplification and DNA array detection. Our technology will eliminate the requirement of sophisticated proteomic instruments, radioactive labeling and large scale automation, yet will possess the potential to detect hundreds of low level proteins in a simple assay. We have named the novel protein detection technology Multiplexed Quantification Using Antibodies and T7-amplification, or MultiQUANT. In Phase I, we will generate RabMAb pairs for 3 BW biomarkers. Concomitantly, we will validate MultiQUANT technology using anti-fibronectin RabMAb pairs that we already have in our possession. In Phase II, we will develop the MultiQUANT system for several dozen BW biomarkers.

Title:Advancing Training Techniques of Non-Invasive 3-Dimensional Ultrasound Sound Technologies for both Diagnostic and Therapeutic Applications
Abstract:Ultrasound is known to be an excellent imaging modality for trauma cases due to its portability and versatility. These factors allow ultrasound to be particularly suitable for battlefield imaging and diagnoses. However, the modest display technology and lack of intelligent systems do not allow battlefield ultrasound to live up to its true potential. In this work, UtopiaCompression proposes the development of a novel three-dimensional hand-held display device and analysis package that is powered by artificial intelligence and highly sophisticated adaptive models of external and internal anatomy that will dramatically increase the diagnostic power of battlefield ultrasound. Using this non-invasive diagnostice imaging technology, a medic would be able to gain and utilize information that is currently either unappreciated or simply unavailable. The power of this medical diagnostic imaging system stems from its adaptive capabilities and its intelligence in localizing anatomy of interest with respect to certain anatomic landmarks and displaying and recognizing known patterns and classifications of normal and abnormal anatomy. Furthermore, given this intelligence at display and localization and the ability of the system to guide even inexperienced users to acquire diagnostically useful views, the training times of medics performing medical ultrasound on the battlefield should be greatly reduced. Overall, this system should allow a low cost, highly efficient, and well integrated diagnostic ultrasound system whereby the user is more efficiently engaged with the scanning hardware and imaging tasks. The anticipated result of this research is to produce a user friendly intelligent visual anatomic guidance/decision support system/device backed by an effective 3D modeling and visualization technology that can significantly assist army medics in their ultrasound training and decision making.

Title:Portable Visual Anatomic Guidance System for Diagnostic Ultrasound Applications
Abstract:Waveband Corporation offers to develop a portable 3D visual anatomical guidance solution to support medical ultrasound devices in order to provide military personnel expert assistance in performing diagnostic and therapeutic ultrasound on the battlefield. The proposed solution will be a rugged and easily deployable visual interface to examine and treat the injured or sick in far-forward conditions in which lower-skilled medics would have to acquire and transmit these scans to higher-skilled clinicians working at a remote telemedicine facility. The system, called 3D Anatomically Guided Ultrasound Device will use a state-of-the art portable real-time animation solution to display a high fidelity model of the human body and provide active computer assistance to the medic performing the examination by visually displaying how the image plane of the ultrasound probe moves toward the specified anatomic location as she or he manipulates the ultrasound probe over the combatant's body. Our innovative approach employs Digital Human Technology (DHT) and image guided external registration techniques to measure the 3D motion of the probe and register its location to the precise features of the combatant's body. Therefore, our 3D visualization interface will be easily integratable with any existing ultrasound device used in clinical practice today.

Title:Development of a Field Portable Mosquito Monitoring System with Attractant
Abstract:To increase the ratio of combat to support personnel and to preserve the health of combat personnel. Accurate surveillance of disease carrying mosquitoes provides risk assessment for some of the most important military infectious diseases including malaria, leishmaniasis, dengue, and West Nile virus. Current methods only approximately measure the risk, unless dangerous human-bait collections are performed. Better methods would reduce the number of vector control personnel required because their efforts could be targeted to the most problematic locations. Improved vector control would reduce the number of cases of disease among combat personnel. Development of a field portable mosquito monitoring system to identify the true disease risk (from disease vectors) in an operational environment is therefore a high priority for the Department of Defense; a portable device ready to use anywhere that electronically scores the number of disease carrying insects. We envisage a field portable, durable, light, remote mosquito monitoring system that incorporates observational software with more robust algorithms to handle lower contrast settings with higher background noise levels, into a small "data logger" type device used in conjunction with a miniature camera(s)/ imagery device to accurately record both visual and time duration data of mosquitoes landing on an artificial attractant surface. This system would be used in combination with an attractant-monitoring surface.

Title:Noninvasive Treatment of Hemorrhagic Shock
Abstract:Hemorrhagic shock is the leading cause of death in combat injuries. This application focuses on a novel way to treat hemorrhagic shock using a new device called the inspiratory impedance threshold device (ITD). The ITD increases blood pressure and survival rates in animals in hemorrhagic shock. Phase I studies in human volunteers are intended to demonstrate proof of concept that use of the ITD is a) feasible, b) tolerable, and c) will increase cardiac stroke volume and stabilize blood pressure in normotensive and hypotensive subjects. In spontaneously breathing subjects the ITD creates a small vacuum within the chest, forcing more blood from the extra-thoracic veins into the heart with each inspiration. This results in an increase in blood pressure, without an immediate need for intravenous fluids or surgical intervention. Phase II studies will focus on use of the ITD in volunteers subjected to hypotension simulating battlefield shock in a lower body negative pressure chamber and in hypotensive patients in the emergency room. The studies are designed to demonstrate that the ITD can "buy time", until more definitive care is available. The studies will shed new light on the mechanisms and treatment of hemorrhagic shock, with important military and civilian applications.

Abstract:An extremely capable team of M Cubed Technologies and Simula is proposing to replace existing ceramic-based small arms protective insert (SAPI) personnel armor plates with hard-faced metal matrix composite (MMC)-based products. This new product will offer much greater durability due to the relatively high fracture toughness of MMCs relative to ceramics. In short, the program will produce MMC tiles, examine hard facing of the tiles via traditional thermal spray processes, and characterize the products for physical and ballistic properties. Variables to be studied will include the MMC composition, the type and thickness of hard facing, and the hard coating process. Finally, an economic analysis of the most promising system(s) will be made, with a comparison to the current ceramic-based systems. The strengths of the team members will be utilized, such as M Cubed's expertise in developing, characterizing and commercializing advanced materials; and Simula's expertise in designing, testing, manufacturing and fielding advanced armor systems.

Title:Development of Stitchless Seaming Equipment
Abstract:A technology has been developed whereby a polymer (plastic) is delivered through a nozzle onto an area to be seamed causing the polymer to bond to the substrates to which it has been applied. This is accomplished by coaxially delivering laser energy in the plastic as it is being applied. The laser energy coaxially delivered in this way is referred to as Laser Enhanced Bonding (LEB). This process is patented (Patent #5348604). The name of the technology is copyrighted and is referred to in the textile industry as LightSeam. The resulting seam is impermeable, flexible, environmentally safe, long lasting, and aesthetically pleasing. Butt seams generated utilizing LEB demonstrate impermeability approaching or exceeding parent material strengths. This impermeability extends from helium and other gasses to blood pathogens, chemicals, water, and any other characteristics the parent material has been engineered to achieve. The technology allows for the use of virtually any polymer, to be used in conjunction with virtually any complex substrate construct. LEB allows common off-the-shelf polymers to be used in applications previously reserved exclusively for solvent based technologies (neoprenes, rubbers, leather, etc.). This is an incredibly significant environment opportunity. No comparable seaming technologies exist today!

Title:Portable, Re-Usable, Non-Electric Beverage Chiller
Abstract:Soldiers must drink over a gallon of water a day to operate safely and effectively in hot climates. We propose to develop an individual cooling element that can cool an individual soldier's drinking water to boost consumption. The unit is portable, re-usable, requires no electric power, and can meet the Army's specifications for cooling capability and light weight. In Phase I, we will prove the feasibility of our approach by demonstrating the cooling process in the laboratory and showing that the Phase II prototype can meet the Army's specifications. In Phase II, we will build prototype coolers and demonstrate them under realistic conditions.

Title:Development of Silent Hook and Loop Closure System
Abstract:Current hook and loop products bear the producing of noise burden which is of increasing concern to the military community and is an irritation in some commercial applications. Similar to zippers, which have a "zipping noise, snap fasteners and plastic buckles which have a "clicking" noise when either engaged or disengaged, the "ripping" noise generated by hook and loop has become a product standard. The SBIR seeks to enhance technology by collaborating with industry and academia, harnessing these talents with the development of a silent hook and loop (touch fastener) closure system where currently available products are extensively used and is at its loudest. A silent closure system will offer stealth field operation for the individual soldier, especially on reconnaissance mission, and battalion levels where soldiers are gathered and noise must be kept to a minimum. Combat based uniforms that require stealth attributes, will be quieter in varying climatic conditions, resistant to mud and lint pickup in laundering. Opportunities to revolutionize the hook and loop fastener market exist through the purview of this SBIR, developing a lighter weight, more flexible without loss of holding strength product that offers characteristics that counter detrimental qualities in current technology.

Title:Modular Parachute Concepts
Abstract:Modular concepts will be applied to round parachutes and parafoil parachutes for the purpose of improving utility and reducing cost. Round parachute designs will be formed from the alteration of uniform fabric panels and limited sewing operations. Fabric panels of round parachutes will be connected with structurally suitable cordage ties to facilitate rapid fabrication and maintenance repairs. Parachute geometry, aerodynamic performance, and reefing capability for designs employing the modular concepts will be demonstrated. Parafoil parachute designs will be formed by lacing the canopy sections or cells together for allowing dissection and piece part recovery as desired. The lacing technique used to connect the parafoil cells will employ processes like those used for the mid-span reefing opening load management method. The canopy geometry and aerodynamic performance that results from application of the modular concept will be similar to traditional parafoils. Release of the parafoil modular sections will also be demonstrated during flight as a method for transitioning the gliding system to a vertical trajectory for landing.

Title:Micro-Atomizing Logistic-Fuel Delivery System
Abstract:Given the high pressures required to micro-atomize logistics fuels, we believe the smallest and safest Micro-Atomizing Logistic-Fuel Delivery System can be achieved by using a pre-combustion vaporization strategy. State-of-the-art capillary pumps can gasify high-viscosity liquid fuels with sufficient velocity to design a passive air-entrainment system. A device based on capillary pump technology can meet the target 300 watts, "deck of cards" size requirement with a relatively small amount of startup thermal energy. An on-board battery-powered heater will be used for start-up in cold conditions. An MSR capillary pump micro-atomizer can be adapted to power a wide range of combustion driven, man-portable applications for the Objective Force Warrior.

Title:A Low-Power Micro-Atomizer for Logistics Fuels
Abstract:Soldiers in the field require compact portable combustion-fired devices for cooking and heating, but existing hardware is not capable of using the heavy logistics fuels (JP-8 and diesel) that are most readily available in forward locations due to their atomization and evaporation characteristics. An innovative micro-atomizing device is proposed that will generate fine aerosols of logistics fuels to promote rapid vaporization. The device will be compact and consume only limited electric power, making long-term battery operation practical. The technology behind the device has been demonstrated for other aerosol generation applications and can be readily integrated with a wide range of combustion devices. Phase I will demonstrate feasibility by building and testing a proof-of-principle device. Phase II will involve fabrication and testing of prototype micro-atomizer devices culminating in the delivery of hardware for initial field-testing and demonstration.

Title:Hydrogen Capture or Utilization in Mg/Fe Based Chemical Heaters
Abstract:An inline method is proposed by Westford MicroCells to capture and use the hydrogen released from flameless ration heaters. Our proposed approach electrochemically reacts the hydrogen to form electricity, heat, and water such that no hydrogen is released to the environment. The electricity generated by the electrochemical reaction may be used to operate external electronic conveyances such as digital equipment, radios, computers, and battery chargers or the electricity may be used with integrated electrical heaters within the ration or heater unit. During the Phase I program, we will demonstrate the electrochemical reaction process culminating in a heater unit that readily integrates with the flameless ration heater. The Phase I program will result in an alpha-prototype unit along with a preliminary design of the complete unit. During the Phase II program, we will develop, demonstrate, and deliver a beta-prototype of the proposed electrochemical hydrogen reactor.

Title:Antimicrobial and Hemostatic Wound Dressings
Abstract:Hemorrhage, infection, and infection-induced sepsis are leading causes of death after trauma on the battlefield and in the civilian community. Both problems are being exacerbated by the increasing frequency of rapid deployment and intense conflict followed by delayed troop evacuation times. Most current efforts to develop advanced wound dressings have focused either on infection or hemorrhage, but not both, and have generally resulted in complicated and expensive solutions. Luna Innovations proposes to develop low-cost antimicrobial and hemostatic wound dressings via topical treatment of conventional textile-based wound dressing materials in a project that combines technologies from textile science, polymer science, biomaterials science, and biochemistry. A naturally occurring and abundant polymeric compound that is biodegradable and possesses both antimicrobial and hemostatic properties will be covalently bound to and/or crosslinked within the woven textile structure of current wound dressing materials on a molecular level. The resulting material will combine the look and feel of current dressings with an enhanced ability to stave off infection and stop blood loss by promoting coagulation.

Abstract:Under this Phase I effort Triton Systems will develop a novel material that will incorporate advanced bio-textile technologies to provide advanced skin and/or wound infection barrier to the war fighter in combat operations. Utilizing Triton's proprietary fiber treatment and coating processes, fibers will be produced with broad-spectrum anti-microbial properties. These fibers will be able to be incorporated into textiles for uniforms using all conventional techniques- nonwoven, woven and knit- which can then be used for treatment of wounds and abrasions quickly, therefore avoiding more debilitating infection brought on by delays in treating wounds resulting from waiting to seek medical attention. This novel material will allow the soldier in a battlefield situation to easily treat injuries, as the antimicrobial capability is an inherent part of the fabric.

Title:A Precision Height and Velocity Sensor for Airdrop Applications
Abstract:Accurate estimations of the height and velocity of airdrop payloads are required to trigger soft-landing systems. These systems have a limited deceleration window, so robust and reliable estimations are required. Current systems rely on a 24-foot stick to trigger the deceleration. This approach is not ideal, and an electronic sensor would be preferable. Radar, sodar, and lidar sensors have been evaluated for this role with varying degrees of success. Foliage and vegetation prove troubling for many of the sensors. However, sodar has been shown to successfully penetrate ground vegetation at certain frequencies. Creare proposes to develop a lightweight low-cost sodar sensor. In addition, we will investigate the value of fusing sodar data with data from other sensors in an optimal estimation algorithm to provide increased accuracy and reliability. In Phase I, we will select an optimum sensor suite based on a careful trade study of the cost and accuracy associated with different sensor component configurations. We will design a prototype height and velocity sensor incorporating the selected component set and prove its feasibility through a simulation based on measured component performance. In Phase II, we will build and test the prototype HVS at Creare and also in the field.

Title:Flexible Aerogel Insulation System for Rapidly Deployable Army Shelters
Abstract:Aspen Aerogels, Inc. (AAI) proposes the development of silica aerogel-based, flexible, insulation systems for Army shelters as a direct replacement for the current multi-layer, cloth-based insulation blankets. The superior thermal resistance of aerogel materials will provide an insulation system with excellent thermal resistance compared to current shelter insulation solutions with an 8x reduction in thickness and total volume. AAI's unique flexible aerogel insulation blankets will allow these high performance insulation materials to be packed efficiently for storage and shipment and will maintain thermal properties through multiple strike and erect cycles. In addition, the inherently low flammability of the silica matrix of the aerogel will reduce the flammability of the overall system and reduce the thermal signature of soldiers using the tent. On the proposed effort, AAI will team with Johnson Outdoors to develop the insulation for shelters such as their Modular General Purpose Tent System (MGPTS). The new insulation materials developed on this program will improve the mobility and sustainability of ground forces and improve the effectiveness, safety, and comfort of soldiers in extreme hot and cold environments.

Title:Body Conformal Cables and Connectors
Abstract:Current military cables and connectors tend to be heavy, bulky and are not conducive to comfortable body contact, particularly when worn for extended periods of time. They are stiff and have round profiles that cause excessive pressure on the body. They also tend to have insufficient bend relief, and mate with system components at odd angles resulting in lengths of the cable not contacting the body which is a snag hazard. Foster Miller proposes developing a stretchable body conformal integrated personal area network capable of transmitting power and data, and supporting electronic subsystems such as personal wearable computers, communications, sensors and GPS. The proposed network will take the form of narrow appliqu‚d elastic textile cables and an associated set of low profile connectors. Technologies to be investigated in Phase I could easily be leveraged to implement broadloom woven or knit conformal electrotextile garments if desired. Electrical performance, durability, design for wearability, and connection convenience will be addressed by the Foster-Miller team. Building on substantial experience of the team-members and their ongoing joint work, initial prototype elastic cables and CAD drawings of proposed connector designs will be evaluated and delivered within the Phase I program.

Abstract:The U.S. Army is seeking a wearable, ergonomically-designed wearable electronic network to be integrated into military protective clothing. To meet this Army need, Physical Optics Corporation (POC) proposes to develop a new Modular Enhanced Systemic Hardware Network (MESHNet) to be integrated into an existing MOLLE (Modular Lightweight Load-Carrying Equipment) vest. The MESHNet will comprise wearable connectors, embedded cables, a wearable internal antenna, and a tactile sense subsystem. MESHNet will be fully compatible with existing military hardware, and will reduce procurement and logistics costs. MESHNet will integrate body-conformable optical/electrical connectors with the POC developed WITS (wired integrated textile seams) and embedded fiber routing system, wires and optical fibers in the fabric seams along the natural contours of the body. The wearable snap-fastener will interconnect POC's universal sensor interface module (USIM) with the MESHNet system at any access point within the system without any manual configuration so the dismounted soldier can affix any type of sensor that has been USIM-enabled to any part of the MESHNet system.

Title:Rigidification of Flexible, Inflatable Composite Structures
Abstract:Highly-mobile military missions have a need for lightweight, rapidly deployable structures. Advances in inflatable airbeam technology has allowed the rapid deployment of lightweight structures. However, inflatable airbeam technology may not be the optimum solution for long-term facilities, where high durability and low maintenance are extremely important characteristics. Meeting these characteristics will ensure that the structure will not collapse due to inadvertent loss of air pressure. These characteristics are best met with an inflatable structure that remains structurally sound when deflated. A rigidizable inflatable airbeam similar to structures used by NASA in space can provide the desired durability and maintenance levels. The objective of this proposal is to demonstrate the technical feasibility of field rigidization of rapidly deployable inflatable beams. The state-of-the-art for lightweight inflatable rigidizable beams has been advancing for the past several years, primarily for space applications. These beams offer unique advantages for achieving reduced overall mass and packaging volume while providing high structural efficiency. Ultimately, these beams will be used as frames for fabric-skinned structures to provide enhanced durability for long-term deployments.

Title:Rigidification of Flexible, Inflatable Composite Structures
Abstract:Airbeam shelters are used for military deployments, disaster relief, and commercial shelters. The advantages of airbeam shelters include lightweight, low pack volume and rapid deployment and strike. When a shelter is deployed for an anticipated long duration at a given site, it would be advantageous to rigidize the airbeams to eliminate the need to maintain inflation pressure. A number of rigidizing materials and technologies are known. These include thermosetting resins whose cure is triggered by a variety of methods, thermoplastic composites, foam-filling, and water or solvent evaporation-hardening materials. Vertigo will employ a systems engineering approach to rigidizing airbeams which will address material compatibility, application methods, packaging materials, storage methods, rigidizing after deployment, and will work toward the objective that no hazardous or polluting emissions or byproducts are generated. The major steps in the systems approach will include a requirements analysis to establish the operational need. Vertigo will then identify and evaluate candidate solutions including pre-impregnated structures, post-infused structures, foam filling, foam sandwiches, concrete pre-preg and shotcrete. Vertigo will fabricate and test samples of airbeam materials with candidate solutions. Vertigo will document the results in a technical report. A Phase I option will fabricate a prototype rigidized airbeam with the leading solution.

Title:Enhanced Lethality Munitions for Army Applications
Abstract:In order to destroy ballistic and cruise missile threats with chemical, biological, HE or nuclear warheads in hit-to-kill or shoot-to-kill scenarios by PAC-3 or THAAD like systems (under the realities of limited targeting accuracy) lethality enhancement is needed. Discrimination of balloons and the potential RV kill in the exo can also benefit from more lethal warheads. Highly energetic-reactive composites of several densities have been shown to increase damage to simulated RV targets and balloons by at least a factor of ten at velocities close to 5 km/sec. The proposed program describes several formulation approaches, which will improve material properties and reduce production costs accelerate technology insertion and transition the technology into a stage where missile designers can identify uses as reactive projectiles or reactive missile structure members functioning non-parasitically prior to impact. Several synthesis concepts will be evaluated and all pertinent measurements will be made to establish acceptable physical and reactive properties. As an optional task, ballistic evaluation is proposed against a realistic target set.

Title:Advanced Algorithms for Tomographic Imgaging
Abstract:Current LIDAR-based ATR systems generally fail to exploit orientation information preserved in multi-view image datastreams. We propose to transition and adapt a novel technique that FTI developed in 1998 for Air Force high-range-resolution (HRR) radar signature classification to the LIDAR ATR problem. The approach is based on comparative analysis of the temporal LIDAR (or HRR) signatures obtained from multiple target views and on exploitation/fusion of target-related signature redundancies. We have demonstrated that the accuracy and fidelity of the associated algorithm approaches 100% Pd with 0% RFA as the number of independent profiles is increased. However, in the HRR application, the number of available source pulses was constrained severely by hardware limitations. Within the currently considered LIDAR applications, we expect to see considerably more independent LIDAR return profiles for each target; and thus we expect to be able to exhibit superior classifier performance. In Phase I, we will design and develop a software solution to optimally exploit multi-view LIDAR signatures; and adapt our algorithms for demonstration using GFI or in-house data. Phase II will develop advanced LIDAR ATR software to run on low-volume, low-power hardware (COTS components) that can support embedded real-time computation.

Title:Iterative Tomographic Algorithm for Laser Radar Imaging of Unmanned-Aerial Vehicles
Abstract:As unmanned-aerial vehicles (UAVs) become more prevalent, they represent a unique threat to deployed ground forces overseas and population centers in the US. The development of a robust imaging and surveillance capability targeting these aircraft is critical. A new tomographic reconstruction algorithm, Tomographic Reconstruction of Active Imaging Ladar Signals (TRAILS), is proposed for ground based laser radar imaging of unmanned-aerial vehicles (UAVs). TRAILS iteratively corrects for inaccurate UAV motion estimates and unavoidable limited-angle distortion. Limited-angle distortion is expected due to the short sweep angle over which the target motion is determined. The degree of limited-angle distortion is characterized for a UAV, including determination of observable features and specification of target trajectories for which the reconstruction is optimum. The proposed algorithm is benchmarked for real-time parallel implementation using a Beowulf cluster. The radar signal is simulated using a facet-based UAV QUick Image Display (QUID) model that includes the effects of oblique angle scattering and shadowing. Iterative reconstruction is applied to these higher order models to determine limited-angle distortion, motion solutions, and algorithm run times. The fidelity of the image reconstruction is verified by overlaying QUID wireframes projected into the image plane.

Title:Advanced Virtual Environment Haptic Simulation
Abstract:Virtual training environments are becoming increasingly important to the U.S. Army for training warfighters as the Army transitions to Objective Force. Training systems are providing more realistic battlefield contexts for the dismounted soldier, increasing soldier immersion and providing a better basis for transfer to operational systems. However, in support of better simulation, the incorporation of haptics has lagged behind the simulation of visual and auditory cues. Reasons for this include the difficulty of simulating tactile information, limitations in hardware and software supporting haptic systems (e.g. restricting movement of users), and the lack of research on how best to utilize haptics. The proposed work is intended to advance the utilization of haptic technologies in virtual training environments. Specifically, CHI Systems, Inc. proposes to team with the University of Central Florida's Institute for Simulation and Training (IST) to (a) provide recommendations for haptic technologies that can be used to support training in virtual environment (VE) training systems, and (b) provide a haptics system design. In Phase I we propose to analyze three high payoff training applications and identify haptics technologies that can be used to support training in these areas. The product will be a set of recommendations to be published as well as a haptic system design tailored to a specific training application and VE. In Phase II we propose to implement and evaluate the haptic system.

Title:Full-Body Haptic Simulation
Abstract:Current immersive virtual environments provide the participant with realistic representations of many of the senses, including sight, sound, and even smell. However, they do not provide the ability for the participant to feel the environment. There are existing haptic-based products that can solve part of this problem (such as force feedback joysticks), but no product meets the diverse needs of adding the complete ability to feel to a simulator. In order to accommodate a realistic sense of touch, the system must provide tactile information (such as textures), thermal information (hot/cold), and applied forces. In order to be operationally compatible with training simulators, the system must be unobtrusive and untethered. Finally, in order to provide for the most usability, the system must be capable of supplying this sense of touch over the participant's entire body. Currently, no system exists that can meet all of these requirements. Cybernet has extensive experience in the development of haptic systems and PC-based simulations (including training simulations that integrate force feedback). Cybernet proposes to leverage our experience in these areas to create a design for a system capable of producing the required sense of touch.

Title:High-Precision, Expendable, Six Degree-of-Freedom Sensor
Abstract:Innalabs, Inc. has developed a concept based on ferromagnetic fluids that has the potential to serve as an alternative to MEMS based inertial measurement units (IMUs). It has the capability to precisely measure linear and angular acceleration in all three axes (six degrees-of-freedom). When the sensor detects position change in x, y, and z axis (movement along an axis) and orientation change in pitch, roll and yaw (movement about an axis), the sensor reports that movement from an initial position. The sensor, once "initialized" would be used to track movement and orientation, such as exactly where an individual weapon is and where it is pointed. The fundamental concept is to place a nonmagnetic object in a magnetic fluid inside of a container. Then, using DC currents on coils to create small electromagnetic fields, any displacement of the object will cause a change in relative distances between base points of the container and nonmagnetic object, and trigger a resultant change in the electromagnetic fields. Sensor can measure amount, rate, and ultimately acceleration of the displacement using the coils as transducers. This displacement can be along or around any axis, in other words, six degrees of freedom.

The channels can be precisely patterned using standard microelectronics technology. The GMR sensors have advantages of high-resolution, small dimensions, low cost, low power, temperature compensation, and intrinsic shock resistance. Different sensing modes and ranges of measurements are possible with the proper choice of magnetic particles and suspension fluids. The proximity of the sensor to the magnetically-tagged inertial mass, and the ability to densely pattern GMR sensors, should be ideal for achieving high sensitivity. The inertial sensor proposed here may be more shock resistant and thermally stable than the micro-electromechanical (MEMS) suspended structures used in commercially available accelerometers.

Title:A Mixed Initiative Team Performance Assessment System (MITPAS) For Use in Training and Operational Environments
Abstract:Military forces of the future will use mixed manned /unmanned forces for a broad variety of functions. Measurement of overall effectiveness in these mixed initiative systems will be essential in order to achieve optimal system performance levels. Behavioral measures of both human and unmanned performance obtained in system simulations or in live exercises will be used to continuously diagnose performance and identify required areas of training requirements. Likewise, specialized training will be necessary in order to leverage the complementary cognitive functions of human and machine to forge fighting entities and units with capabilities superior to those of humans or machines in isolation. This proposal describes an innovative approach to developing a Mixed Initiative Team Performance Assessment System (MITPAS). The MITPAS consists of a methodology, tools and procedures to measure the performance of mixed manned and unmanned teams in both training and real world operational environments. Our objective is to provide a turnkey MITPAS software system running in the OneSAF-OTB environment, integrated with automated data collection functions and containing protocols for evaluation of various manned/unmanned team configurations in selected event-based scenarios. As an option we propose to develop and demonstrate a specific application within a realistic FCS battlefield scenario.

Title:Adapting Intelligent Tutoring System for Assessing Collaborative Skills
Abstract:Effective team training is at the heart of enhanced mission effectiveness for military operations now and into the foreseeable future. However, despite numerous advances in intelligent tutoring system (ITS) technologies for individual skills, these systems have yet to fully address the "coach-less" instruction of teamwork skills. Accordingly, in this project we propose to build a prototype Intelligent Teamwork Tutoring System (ITTS) that is targeted at supporting Army team training. More specifically, our primary objectives for Phase I include: 1) The identification of critical teamwork skills relevant to training Army teams; 2) The creation of a high-level framework for an ITTS; 3) The specification of a high level design for a simulation-based testbed; and 4) The development of a proof of concept demonstration. In Phase II, we will build on this work by developing a prototype version of this system for an Army team, by testing and evaluating its effectiveness, and by engineering the necessary extensions for application to larger scale teams. In Phase III, we will transition and market the eventual product, the Intelligent Tutoring System for Adaptive Team Training.

Title:Adapting Intelligent Tutoring System for Assessing Collaborative Skills
Abstract:The Army's vision of the future included an Objective Force, a highly-mobile and lethal organization of warriors, which will be supported by the Future Combat Systems, consisting of a systems infrastructure that will integrate training, operations, and maintenance. The Objective Force will be required to rapidly assemble and deploy units in response to the dynamic environment such as the recent war in Iraq. The ability to coordinate these operations successfully will hinge upon the team performance skills of these distributed units. Consequently, team performance training is a necessity in achieving the vision of the Objective Force. Due to the distributed nature and rapid response of the Objective Force, training will need to be conducted in the field or remote locations. Technology innovations have resulted in intelligent tutoring systems to provide instructor-less training on a PC or other mobile computing device. However, intelligent tutoring technology has thus far focused on individual training. This Phase I effort will build upon the current intelligent tutoring technologies to extend their applicability to design a collaborative training intelligent tutoring architecture. In Phase II, this architecture will be implemented as a collaborative intelligent tutoring prototype.

Title:Software Tools for Modeling Urban Details
Abstract:The ability to represent and model buildings, interiors, and subterranean areas for simulation has become increasingly important for a number of disparate markets, including government applications in simulation of military operations in urban terrain, chem/bio flow analysis, and first responder and anti-terrorist training, as well as commercial applications in real-time visualization of planned developments, traffic and transportation flow analysis, and viewshed inspection. However, current tools do not address the automated generation of building interiors and critical underground structures, let alone the integration of these generated models into a consistent three dimensional representation suitable for supporting modeling and simulation activities. CAD tools provide capabilities well suited for geometric modeling, but not the attribution or topology necessary to drive constructive simulation; consumer products lack representations for attribution, topology, and rigorous geographic coordinates. This Phase I effort will produce a detailed design of an efficient, flexible, and powerful urban authoring tool that would serve as an enabling technology for numerous government and commercial interior and subterranean urban modeling applications. Such a tool will enable users to easily and accurately construct realistic geospecific and geotypical interiors and subterranean structures in well-populated urban contexts, exportable with full attribution to current simulation formats.

Title:Software Tools for Modeling Urban Details
Abstract:Vexcel proposes to build an urban modeling system by combining the SketchUp 3D CAD tool with the photogrammetry based as-built modeling tool Foto-G. These tools represent the state of the art in both, intuitive 3D modeling user interface, and automation supported 3D feature extraction. The final result of this effort will allow the Army to create large simulation databases almost fully automatically from spaceborne, aerial, or handheld still images or video sequences. Full comliance with all relevant database standards will be provided. Automated attribution with non-visual characteristics will be supported. The cost of urban models and the time to create them will be reduced by an order of magnitude compared to the current manual approach.

Title:Base Object Model (BOM) Aggregation Framework
Abstract:The aggregation of entities is considered a practical approach for managing large-scale simulation exercises and improving performance. The key for aggregation to work is to reduce independent high fidelity models to more efficient, lower resolution models that can then be grouped together to create combined model sets. While practical, aggregation is not easy to implement and universally apply by the players within a federation. Furthermore, models used to represent entities and interactions are not typically built with aggregation in mind. Aggregation capable models are instead needed, which would allow differing levels of detail or resolution to be dialed up or down for any one model. A promising technology that encourages the representation of multi-resolution models and combined model sets are Base Object Models (BOMs). Based on the potential BOMs provide, SimVentions proposes to design and develop a BOM Aggregation Framework that encourages multi-resolution models and facilitates aggregation and de-aggregation.

Title:Multi-Resolution Representations and Interactive Visualization of Large Terrain Models
Abstract:We propose to develop multiresolution representations and algorithms for synthetic terrain environments. They will be used for representing large terrain models as well dynamic and atmospheric simulations. Our ultimate goal is to increase the validity of the simulation by incorporating the multiple models at varying resolutions. We will use the OneSAF simulation Product Line Architecture Framework (PLAF) as a reference, and evaluate the use of static and dynamically generated multiresolution models within that framework. Moreover, we will develop novel multiresolution reprsentations of large scattered datasets and use them for interactive display as part of Phase I. We also propose a Phase I option to develop efficient line-of-sight (LOS) computations algorithms based on the multiresolution representations for large terrain environments. If successful, the proposed representations and algorithms can significantly improve the performance of OneSAF simulation framework.

Title:Base Object Model Multi-Resolution Terrain Representations
Abstract:With the advent and implementation of faster computers and peripherals in simulations came the realization that models must have varying degrees of complexity depending on their use within a specific simulation. Terrain representations, for instance, have many physical models which include mobility, thermal, seismic, buildings, flooding and acoustic to name a few. Depending on the application of the model, different fidelities are necessary. With increased demands and diversity in simulation models comes an opportunity to provide methods to store and distribute models at various resolutions with specific attribution and specified formats; to provide methods for the incorporation of multi-resolution models into dynamic simulations; and, to provide methods to link real-time data, live and constructive entities and simulations together through a collaborative capability/mechanism. SimVentions recognizes the opportunity exists with the use of Base Object Models. SimVentions proposes research into methodologies, processes, tools, and algorithms needed to produce and/or represent these multi-resolution models. SimVentions will also research concepts for interfacing and interoperating between simulation, architectures, frameworks and collaborative / enterprise environments that will support informational flow, communications, situational awareness, weapons and survivability and that will integrate with new systems such as FCS and MATREX for sharing multi-resolution models in a collaborative way

Title:Increased Plastic Oxygen/Water Barriers
Abstract:The reduction of the weight of individual equipment components is one of the main objectives in the Army's quest for a lighter, more mobile force. Special attention is required for non-structural components, because the potential for weight reduction without compromising battle field survivability is greatest in this area. Optical components are usually made from glass, which has a high density and, therefore, high weight. High grade optical plastics are available, that could lead to significant weight reduction. Unfortunately today's materials do not provide the necessary non-optical properties desired for a military application, this is especially true in regards to the permeability for oxygen and water Adherent Technologies, Inc has studied the surface modification of polymeric and composite materials using plasma for over 10 years. Plasma induced surface polymerization has been shown to be a powerful tool in changing the surface properties of materials. Thin coats of hydrophobic and oxygen impermeable polymers can be covalently bound to optical materials. Surface polymerization is a fast way to modify existing polymer based optical materials in a way that makes them acceptable for use in a military environment. This technology allows the rapid acceptance of polymeric materials for optical parts at low cost.

Title:Lightweight Multifunctional Slipring
Abstract:To reduce the weight and size of Future Combat System ground vehicles, Physical Optical Corporation (POC) proposes to develop a new Lightweight Multifunctional Slipring (LMFS) based on metal fiber-rotary band contact (RBC), active fiber optic rotary joint with time and wavelength division multiplexing (TDM and WDM) capabilities. This compact rotary joint will allow 360 degree free rotation for multiple electrical (DC and AC) circuits, will transmit wideband optical signals in both directions and will pass hydraulics/pneumatics such as air, water, and lubricants. LMFS will be highly reliable, maintenance free because of its metal fiber rotary-band contacts, contactless magnetic slipring for AC electrical signals, and WDM/TDM signal conversion for single mode fibers with extended beam optical transmission. In Phase I POC will demonstrate a working model of the proposed slipring with all required functions. In Phase II, POC will fabricate and test a full-scale engineering prototype slipring assembled in accordance with the TACOM specifications.

Title:Low Cost Materials, Designs, and Manufacturing Processes for Robust Tubular Solid Oxide Fuel Cells (SOFC)
Abstract:A low cost method for manufacturing cathode SOFC tubes is proposed. This method provides more uniform properties, is easily scaled to high volume production, and is less expensive than more conventional ceramic processing methods, such as extrusion or isostatic processing. It involves preparation of a colloidal suspension of particles containing a small amount of organics, low pressure injection into a die, solidification by a temperature change, removal of tube(s) from the die, drying and firing to a temperature that provides desired properties of permeability, mechanical strength and electrical conductivity. Both short and long cathode tubes (30 inch) have been made using this process; however, neither the process nor the composition are optimized and significant improvement can be expected through the successful completion of this program

Title:Low Cost Materials, Designs, and Manufacturing Processes for Robust Tubular Solid Oxide Fuel Cells (SOFC)
Abstract:New power systems are needed for U.S. Army vehicles, to enhance fuel efficiency and reduce reliance on the fuel supply train. Solid-oxide fuel cell systems provide compelling advantages in fuel efficiency, fuel flexibility, and fuel impurity tolerance. The same fuel efficiency advantages provided to military applications, when extended to commercial vehicles, would have an enormous impact on fossil fuel consumption, pollution emissions, and transportation costs for the next century. Developmental programs are in place, but require new materials and new processing routes to achieve manufacturing cost and performance targets. The objective of this Phase I SBIR project is to develop low-cost materials and fabrication methods for producing tubular SOFCs while maintaining high mechanical strength, toughness, and electrochemical performance. The successful completion of this program will significantly improve tube manufacture for the Turbo Fuel Cell Engine. By tailoring the manufacturing process to provide consistent extrusion, drying and sintering performance, the resulting improvement in cell reproducibility and enhanced manufacturability will enable larger scale demonstration of the design. In addition, by focusing materials enhancement on the development of interchangeable interfacial layers, a compromise of demonstrated performance and design flexibility will be achieved.

Title:Hydraulic Actuated Roll Inhibited Active Suspension for the Army
Abstract:Vehicle stability is typically compromised when the high mobility, payload and transportability requirements placed on military tactical vehicles are dependent on conventional passive suspension technologies. Rod Millen Special Vehicles (RMSV) is confident that with the proper selection and development of an advanced suspension system for military tactical vehicles, improved stability, safety and performance can be realized. Electronically controlled suspension systems allow the integration of the suspension into vehicle area networks, supporting prognostics and embedded diagnostics. For this effort, RMSV will update its internal database of advanced suspension technologies and perform a systematic high fidelity dynamic analysis to evaluate the relative performance of each candidate technology. The performance of RMSV's prior bolt-on active/semi-active suspension systems will also be assessed in the context of this evaluation. Using HMMWV as a common platform for evaluation allows real-world test data to be used to assess the performance of many candidate suspension systems. A comprehensive trade study, based on dynamic analysis and field test results, will support the identification and development of an optimal suspension technology which will result in improved safety, performance, mobility, driver control and passenger isolation at minimal cost for the Army's fleet of future tactical vehicles.

Title:Biofiber-Reinforced Structural Composites for Use in Matting/Temporary Roadway Panels
Abstract:The Army's goal of deploying faster and farther can potentially be met using biofiber reinforced degradable composites. Fully degradable structural composites require the use of high strength natural fibers, a degradable polymer matrix material compatible with the fibers, and excellent bond strength between the two. In this case, the application for the degradable composite is to assist military vehicles in climbing muddy inclines adjacent water crossings. This challenge requires knowledge and experience in 3 unique areas for a total solution to come to fruition: subgrade reinforcement for roadways, engineering using composite materials, and degradable polymer chemistry. TRI/Austin is unique in that all these areas of expertise can be found under one roof. TRI will use the expertise of its environmental division, which houses the world's first accredited geosynthetic testing facility, to develop the overall strategy required to provide roadway reinforcement functionality through the use of geosynthetics/organic erosion control product hybrids. TRI's mechanical engineering division will develop the composite material structure required to make up the selected reinforcement system. Finally, TRI's polymer materials science division will build on previous research to develop the best biofiber/matrix material system.

The shape-shifting track is shaped conventionally for rough terrain traversal and then transforms into the shape of a wheel for high speed efficient travel over smooth surfaces.

Title:Sentinel: A System for Command and Control of Small Teleoperated Robots
Abstract:We propose to develop Sentinel, an integrated system for command and control of teams of small teleoperated/autonomous robots. Sentinel will integrate technologies for dynamic camera selection, variable autonomy levels, variable-bandwidth communication, and Monte Carlo Localization using GPS, INS, and manual landmark recognition. The Sentinel localization system will enable operators to increase localization accuracy by identifying landmarks visible through robot cameras. This system will also enable robots to use other robots as landmarks, providing increased localization accuracy for all robots and providing fault-tolerance when GPS is unavailable. During Phase I, we will design the integrated Sentinel teleoperation/autonomy system. We will design this system to enable the operator to dynamically change robot autonomy levels based on the current situational demands. We will also characterize the bandwidth requirements for command and control of multiple robots, including the bandwidth-vs-video-quality tradeoffs involved in simultaneously receiving multiple video streams. Also during Phase I, we will design the Sentinel localization system, including the system architecture, user interface, and Bayesian sensor models. We will implement and demonstrate an initial version of this localization system using GPS and manual landmark recognition on a PackBot UGV.

Title:Advanced Robot Vision and Communication System
Abstract:Physical Optics Corporation (POC) proposes to develop a new Active Robot Vision and Communication System (ARVACS) that incorporates active lighting with fully automatic image enhancement, multichannel digital wireless communication, and real-time video compression. This system will be low-power-optimized for battery operation. ARVACS will be based on POC's advanced technologies and existing commercial-off-the-shelf (COTS) hardware and software. POC's technologies will include real-time video compression by an embedded system that can produce 1 kbps to 20 Mbps compressed video (MPEG1-4, DivX, and Wavelet) with less than 15 ms latency, and enhanced wireless communication hardware that is compatible with industry standards such as IEEE 802.11, Bluetooth, and HiperLAN2. The Phase I ARVACS model will utilize a leading image enhancement processor such as the NuCORE SiP-1270 and will provide fully automatic image enhancement functions such as noise reduction, white balance, edge enhancement, error correction, and gamma correction. The major innovation of ARVACS will be fully automatic active lighting with an adapting active lighting controller. In Phase I, an ARVACS feasibility demonstration prototype will be fabricated, which will be further optimized in Phase II for power efficiency on a battery-operated UGV target system.

Title:Intra Vehicle Adaptive Computing with SQUAWB (Secure QoS-enchanced UltrA Wide Band)
Abstract:Ultra Wideband (UWB) technology provides high-speed, low-power wireless networks with a low probability of detection and interception, and is resistant to jamming. This promising technology lacks support above the physical layer to provide capabilities that the Army requires for intra-vehicle communication for real-time, multimedia data streams. ATC-NY proposes to create the SQUAWB (Secure QoS-enhanced UltrA WideBand) protocol to support the efficient use of the frequency spectrum among multiple simultaneous users. SQUAWB will support QoS guarantees and provide security in a dynamic environment in which the underlying capabilities of the physical layer, such as bandwidth, change due to the environment and adversaries. SQUAWB will be developed as a MAC-layer protocol to interface with the physical layer and a middleware layer protocol to interface with the application layer. The middleware layer will use adaptive, reflective techniques to let it adapt to the changes at the lower levels. In addition, the middleware layer handles the security and QoS details that most application programs currently do not handle. In Phase I, we will create the MAC and middleware layer protocols and perform simulations to demonstrate the feasibility and benefits of SQUAWB.

Title:Highly Multi-Perspective Autostereoscopic Display
Abstract:The objective of this Phase I effort is to design and simulate an innovative optical architecture for true, interactive-rate holographic video. Our novel technique takes a contrarian approach to existing multi-view and holographic video systems, which are typically crippled by "jailbar" dark regions, limited viewing zones, and image distortions arising from rendering techniques not intended for multi-perspective displays. The proposed multi-view holovideo system is a highly multi-perspective autostereoscopic display, capable of generating three-dimensional Spatial imagery visible across a 30-degree viewing zone, comprised of 100+ XGA-resolution views. This represents an order-of-magnitude leap in performance over previous approaches. Actuality Systems is a recognized leader in the commercialization of Spatial 3-D visualization systems; construction of a prototype in Phase II will be simplified by the reuse of certain core technologies. The resulting display is amenable to cost- and size-reduction, and will be suitable for use on the desktop, in the cockpit, and eventually in handheld devices.

Title:Replacement of CRT-Based Displays
Abstract:Microvision, Inc. will develop a CRT replacement platform using its MEMS-based scanned beam display technology. Microvision's effort will leverage the knowledge gained in internally funded monochrome feasibility demonstrator and existing MEMS products to jumpstart an effort aimed at developing a fieldable full color display that eliminates many of the disadvantages of current CRTs. The effort will begin by examining and analyzing three candidate architectures that convert non-visible light to visible light to determine the best match to the military's requirements and to provide a platform that can be most readily manufactured and commercialized. After selecting a single architecture, Microvision will then develop a more complete system model of a display according to the selected architecture to predict achievable performance and manufacturability. The model will incorporate Microvision's expertise in MEMS scanning, the limitations of currently available wavelength converting materials, an analysis of color masking techniques, and Microvision's extensive optical and system modeling capabilities. The analysis will inform Microvision's development of a next-stage plan to produce a full-color prototype system. Accordingly, additional deliverables include, a roadmap leading to a Phase II prototype and a realistic commercialization plan for both civil and military Phase III products.

Title:Integrated High-Performance Remote Visualization Capability
Abstract:Digital transmission schemes have the potential to become extremely effective in enabling remote broadband visualization and graphics resource sharing in the LAN and WAN. Intrinsically flexible deployment, low fiber count, global collaboration distances and low image latency are among the many advantages offered by digital technology. Given the ubiquity of transmission in the WAN - whether circuit or packet based- new technologies that take advantage of this infrastructure will be able to expand the reach of high-resolution graphics for visualization applications. For this Project, we will explore architectures that integrate transport and switching in a flexible, cost-effective, remote visualization solution that allows users to extend, switch and remotely collaborate on high-resolution graphics. During this examination, we will look at minimizing the graphics transmission costs through the use of novel compression techniques that reduce bandwidth connectivity requirements. Transmission components will be chosen that take best advantage of both multimode and single mode fiber infrastructures. A modular, scalable graphics switching architecture will be proposed consistent with the "pay as you grow" model encountered in telecommunications. Network management and control software requirements will also be examined.

Abstract:Offline vehicle dynamics simulation software is used to predict the performance of new vehicles as well as to predict the performance of modifications to existing vehicles. By developing software that integrates vehicle models and analytical simulations with virtual immersive environments to allow inspection and collaboration, greater insight and understanding of the performance of the vehicle can be achieved. The objective of this proposal is to develop immersive vehicle dynamics visualization software (IVDYN). This software will import results generated in LMS Virtual Lab, CADSI DADS, McNeil Schwendler's ADAMS, and Realtime Technologies, Inc. (RTI)'s SimCreator. It will also import CAD models from standard environments such as Virtual Lab, ADAMS, CATIA, DADS, PTC ProE and Unigraphics and allow connection of vehicle dynamics results with specific CAD bodies and degrees of freedom. The software will also allow the definition or import of the virtual terrain on which the vehicle was driven. Finally the software will project the resulting simulation in a variety of immersive systems including: CAVE, PowerWalls, and ImmersaDesk settings.

Title:Development of High-Resolution Virtual Terrain for Use in a Motion-Based Simulator with an Image Generator
Abstract:Visual Simulation, training, and virtual prototyping platforms demand ever increasing fidelity. Visual cues such as specular highlights and distinguishable surface contour must be presented to offer a sense of realism in the environment. Use of the visual database for a "glass smooth" terrain database does not provide adequate high frequency queues in motion and haptic feedback subsystems. Realistic surface roughness characteristics must be captured and used throughout the simulation system. This proposal will demonstrate the feasibility of generating, integrating, and overlaying high-frequency roughness characteristics onto both the visual database and in the terrain database. The use of bump mapping and Phong illumination will be investigated as methods of increasing scene realism.

Title:Computational Modeling of Nanocomposite Structures
Abstract:The overall goal of the project is to provide a computational based multi-scale approach to realize the projected extra-ordinary properties of the nanotube-reinforced composites in structural applications of interest to the United States Army. To achieve this goal it is proposed to develop and demonstrate methods that can link atomic scale variations within a meso or macroscopic domain with a strong two-way coupling. The proposed study seeks to develop computational methods based on sound physics and theoretical underpinnings to effectively model the structure-property-processing relationships in nanoscale systems that are inherently separated by scales of many orders of magnitude. The proposed methods account for the effect of nanotube length, diameter, chirality, and orientation distribution on the thermal, mechanical and impact properties of the carbon nanotube-reinforced polymeric composites. During Phase I of the proposed research, the theoretical models and computational approaches will be investigated, and the feasibility of the developed models will be assessed in light of existing numerical and experimental data. In Phase II of this research, numerical implementation of the computational models developed in Phase I will be carried out and the utility of the developed software in the analysis of nanocomposites and nanomaterials of different kinds will be demonstrated.

Title:Modeling of Nanostructures
Abstract:A dynamical derivation of the Dirac wave equation is developed by unifying the torsion and curvature of spacetime in a six-dimensional hyperspacetime supporting closed-circuit affine geodesics that form stable atomic orbitals of a spinning electron. The physical basis of spin is mechanically established. Causality is restored to atomistic phenomena by providing a spatiotemporal basis of Heisenberg's uncertainty by unifying spacelike spacetime with timelike spacetime. The discrete singularities of quantum theory are reconciled with the continua of relativity theory by unifying discrete line-continua in spacelike spacetime with the space-continuum of timelike spacetime. Spacelike and timelike spatiotemporal manifolds are established as being physically coupled by an exchange force that results from a self-generated electromotive force due to the path-dependent parallel-transport of momentum along a closed-circuit affine geodesic in flat spacelike spacetime. The self-generated electromotive force in flat spacelike spacetime accounts for the stability of a spinning electron by compensating the dissipative radiation of the rotating charge.

Title:Integrating Stochastic Engineering Models in a Distributed Environment
Abstract:The main objective of this project is to develop an efficient stochastic-optimization approach that can be applied to large-scale high-complexity Army military vehicle applications in a high-speed distributed computer hardware environment. Specifically, the proposed work will integrate the refined stochastic response models (stochastic field expansion approximations) developed by GP Technologies Inc. with the RBDO Probabilistic Measure Approach (PMA) developed by the University of Iowa. The research project team will explore and refine the stochastic response analysis part of the UOI RBDO approach based on state-of-the-art stochastic field/network modeling and artificial intelligence concepts. The proposed development will also include fast Dynamic Monte Carlo simulation algorithms, plus Bayesian inference for optimal model fitting and selection. Phase I will also provide a probabilistic-design methodology for incorporating the data and modeling uncertainties in the RBDO problem and will explore the application of other non-deterministic approaches to RBDO including multi-objective problems. In Phase I the proposed RBDO methodology will be applied to the Army M1A1 tank road arm component via ANSYS FEA code. The RBDO approach will operate in the distributed environment of hardware available at the U.S. Army. The parallel programming task will be conceptually initiated in Phase I and completed in Phase II.

Title:Exploratory Development for A Controllable Combustion Process for Improved Power-Density and Fuel Economy within Multi-Fueled, Low Heat Rejection Comp
Abstract:The goal of this proposal is to develop a feed back controlled combustion process for high power density, near stoichiometric air/fuel ratio diesel engines, capable of running on multi-fuels, with superior cold start capability. The company, its advisors and suppliers will introduce new innovative concepts to achieve the goal of delivering power greater than 1 hp/lb. Adrenaline Research has developed technology known as the "SMARTFIREr" Plasma Ignition, which will enable an engine to achieve all of the Army's major objectives. SmartFire's high intensity in-cylinder plasma energy will deliver reliable cold starting and good low load operation of a low compression diesel engine, without the need for any external cold start aid. With SmartFire's combustion feedback to the engine management system, the combustion process will be tightly controlled to allow the engine to switch to different fuels on the fly, without engine modification. To achieve the goal of greater than 4 atmospheres of boost; two properly sized turbochargers will be used in series, each one with its own compact intercooler. Selective cooling, in addition to in-cylinder and exhaust port surface treatment will reduce the thermal load, and increase thermal energy delivered to the turbochargers.

Abstract:Baker Engineering Inc. proposes a 4.5 liter opposed-piston, 3-cylinder, 2-cycle diesel engine with a target of 500 hp, weighing less than 900 lbs. to fulfill the Army's quest for an improved power density, multi-fuel capable and low heat rejection compression engine. This 4.5 liter engine offers an opportunity to further advance the opposed-piston combustion technology by building upon the successes proven through previous opposed-piston engine development and testing efforts (prototype engines ranging from 4.1 liter to 8.3 liter). The proposed new 4.5 liter engine design will advance the design of pistons, rods, cranks and other core opposed-piston engine components with the primary emphasis on improving the fuel delivery system and controls, adding a self-sustained turbo charger system, reducing weight, and improving packaging.

Title:Passive Thermal Management for Advanced Vehicles
Abstract:The use of advanced technologies is proliferating on board military and commercial ground vehicles. New power sources such as fuel cells and batteries create unique cooling requirements. The use of electronics for power conditioning, diagnostics and control, and military applications (command and control, weapons systems) leads to ever increasing heat loads which must be rejected from the vehicle. With limited on-board weight and power budgets, an innovative, passive, highly efficient thermal management system is needed. The development of a multi-evaporator, looped heat pipe thermal bus system is proposed to meet such a need. This technology provides the capability to collect heat from disparate sources and reject it from a central location, simplifying the management of the on-board thermal systems. A program is proposed to demonstrate this technology with a proof-of-principle test, and to sufficiently develop a conceptual design to address how a thermal bus would be integrated with a vehicle and show the vehicle level benefits (reduced weight, improved thermal control, increased device reliability and life expectancy). Issues of modularity, control, and adaptability to changing environmental conditions will be resolved.

Title:Virtual Prototyping Vehicle Electrical System Management Design Tool
Abstract:Complex engineered systems such as tactical vehicles and advanced weapon systems involve a broad spectrum of technologies and interactive subsystems that must work synergistically in order to achieve mission goals. Due to the interdependencies between subsystems that comprise the overall system, it is becoming increasingly important to establish a flexible virtual prototyping design and analysis infrastructure that empowers program engineers, managers and/or system integrators to rapidly evaluate design alternatives and competitive technologies and architectures, and to optimize the overall system design. The primary objective of the Phase I effort is to establish the viability of such an infrastructure for electric power/propulsion systems in hybrid-electric vehicles. It is envisioned that a successful virtual prototyping environment will include an extensive heterogeneous models/methods library and a flexible easy-to-use interface that allows rapid configuration of component models, which could be implemented using different simulation languages on a distributed computer network. If the Phase I effort is successful, the Phase II will focus upon the development of this infrastructure and, ultimately, its implementation at TACOM. Although this research will focus on electric power and propulsion systems for tactical vehicles, this prototyping environment will have widespread applications including commercial and/or military terrestrial vehicles, ships, and aircraft.

Title:Transmission and Driveline Development and Their Components
Abstract:This proposal is directed at a fundamental change in military trucks by designing driveline systems as a complete lightweight module manufactured from selectively chosen lightweight components. Current driveshafts, differentials, transfer cases, axles, and brake systems are typically bolted together of cast iron and steel components. If a lightweight aluminum part is included, it is typically substituted for an iron component. The identical mating shape is required for bolting, so the lightweight part is not truly optimized. Therefore, designing an entire module of the best lightweight materials is the only way to truly optimize the system. This allows optimized designs, multi functional shapes, and advanced materials to integrate for a lightweight system. The proposal will design a complete driveline module of advanced materials to demonstrate the weight reduction of this concept. To limit the size of a program for a Phase I SBIR, GS Engineering will design a side plate, axle structure and differential housing as a module. Advanced lightweight materials including magnesium, magnesium metal matrix composites, and aluminum metal matrix composites will be used to optimize the weight of the entire system. This concept can be applied to any military truck, from the FTTS to retrofitting existing HEMTTs and FMTVs. GSE has chosen to design a system for the HEMTT A3 as the platform as it has a current weight reduction program. Oshkosh Truck Corporation will cooperate on this program by providing design information, loading conditions, and engineering support for the HEMTT A3 upgrade.

Title:Transmission and Driveline Development and Their Components
Abstract:U.S. Army ground vehicles such as the Family of Medium Tactical Vehicles (FMTV) use a driveline system to transfer power from the engine to the vehicle's wheels. Modern driveline systems make up a significant amount of a ground vehicle's empty weight. Driveline system components are fabricated from relatively heavy metals that are subject to corrosion damage, and are expensive to manufacture due to the fabrication processes required to form the complexly shaped parts. Innovative driveline system designs that utilize low cost, lightweight, durable materials are required to reduce the weight of the driveline system, while reducing part procurement costs and maintenance costs by eliminating corrosion damage. Texas Research Institute Austin, Inc. and subcontractor Stewart & Stevenson Tactical Vehicle Systems, LP propose to develop cost effective, lightweight, damage tolerant, polymer composite driveline system component designs to replace currently used metallic components in the FMTV tactical vehicles. The use of composite materials will reduce the cost and weight of the driveline system while providing a reliable, corrosion free service life with little or no maintenance costs. The use of lighter weight, polymer composite driveline components will increase the power-to-weight ratio of the vehicle and allow for increased performance or payload.

Title:Develop New Innovative Filtration Designs and Components for Improved Service Life, Performance and Durability
Abstract:A concept is presented for improving the service-life, performance and durability of air filters. This concept proposes to replace disposable fiber air filters with permanently installed self-cleaning filters that can be cleaned by air blast in the opposite direction, without removing the filter from its canister. The proposed self-cleaning filter is made from plastic discs and contains micro-passageways for the airflow. The disc material is robust, allowing it to withstand the intense air blast The proposed study will demonstrate the feasibility of our technology for applications in military vehicles and will carry out a system analysis that supports the goal of eliminating filter replacement. The main tasks will focus on an analysis of military vehicles and their filtration systems, modeling the fluid dynamics of air flow in the complex pattern of micro-passageways and creating an engineering database that will enable design of prototypes. The final Phase I report will clearly show the improved service life of our proposed self-cleaning filter, as well as the efficiency of its operation and its cost savings. A successful implementation in military vehicles will result with applications for commercial heavy- duty trucks and other machinery.

Title:Point of Use Oil Quality Analysis
Abstract:The maintenance of vehicle and support systems is of key importance in Army operations. However, determination of the correct time to perform changes of hydraulic fluids is currently inexact and can be expensive. If fluids are changed too late, significant damage to equipment can occur while if fluids are changed too early, wasted effort a disposal costs are incurred. Determination of fluid health and remaining useful life presently depends on labor intensive, protocol dependent techniques. Makel Engineering, Inc. proposes the development of a microsensor based system to provide continuous in-situ monitoring of hydraulic fluids and automated book keeping by way of bar code scanning of vehicle hood numbers or wireless telemetry and the storage of vehicle and fluid data in a suitable database. The envisioned system will incorporate sensors produced using MEMS and thick film processing techniques and these sensors will be robust, low cost units capable of directly monitoring fluid parameters of interest such as viscosity, conductivity, TAN/TBN, various contaminants, pressure, and temperature. The sensors would be mounted on a dipstick or drain plug and interface with engine control electronics or portable monitoring equipment to improve maintenance procedures. In the case of a portable diagnostic system, the sensors would be incorporated onto a "smart dipstick" and vehicle information would be obtained by a simple bar code scanner incorporated into a handheld computer. In the case of a monitoring system integrated with vehicle control systems, data could be logged continuously and uploaded wirelessly to a main database of vehicle information.

Title:Advanced Military Diesel Engine Technologies
Abstract:The objective of this proposal is to improve Army logistics by permitting the use of diesel engines capable of operation on heavy-hydrocarbon fuels including DF-2 and JP-8, instead of gasoline engines, for small mobile generators and other small motor applications (e.g. utility pumps), thus reducing Army fuel/ fuel distribution costs. Normally, diesel engines do not have sufficient power density when compared to gasoline engines for these applications. A recent University of Wisconsin study identified a significant opportunity for the Army to use durable, reliable, and relatively lightweight diesel engines equipped with superchargers to replace gasoline-fueled engines in mobile generators and other small motor applications. Assuming success, this proposal will satisfy the objectives of the A03-233 program to increase fuel economy, increase power density, and reduce specific heat rejection for small diesel engines. The supercharger will be designed and developed to meet or exceed the engine RAM-D goal of 1000-hour life expectancy.

Title:High Efiiciency, Compact Heat Exchanger for Mobile Equipment Applications
Abstract:This project leads the efforts of advance heat exchanger technology through the integration and convergence of the best emerging methods and materials for increased heat transfer and efficiency. Achieving high efficiency, beyond the present art, involves an in-depth analysis of present heat exchanger designs, by gaining an understanding of application specific demands within mobile equipment such as fuel cells and batteries, to implement new design flexibility, which cycles from new materials impacting new manufacturing methods and vice versa. A plethora of energy generators and consumers both yielding heat sources from power inefficiencies exists in the next generation of vehicles. The requirement to dissipate heat ranges from air-to-air, liquid-to-air, and liquid-to-liquid heat exchangers that are both single phase and multi-phase systems. These processes will perform in the future by taking advantage of new materials, specifically nanotechnology, in order to realize significant gains in performance with new heat transfer methods that potentially have the means to accelerate heat transfer using non-linear design and quantum tunneling. Lastly, new materials utilized for sensors coupled with increasingly powerful control systems will achieve the highest energy efficiency by enabling the entire heat transfer system, including the heat exchangers, to operate at their optimal levels.

Title:Meshless Thermal Analysis of Vehicles Using Distance Fields
Abstract:Computational thermal analysis of vehicles is dominated by model preparation time, typically in the development of surface meshes for import into analysis software. This preparation requires time-consuming creation of new geometry (a mesh) that only approximates the original model. Despite the presence of automeshing capabilities, human intervention is often required to prevent poor quality meshes. We propose to solve thermal analysis problems using native CAD geometry in a system that employs distance-based parameterization of the temperatures. The supporting technology does not rely on a mesh discretization of the geometry and will work with virtually all mesh-based and meshless solution techniques while all boundary conditions are exactly satisfied. With successful commercialization of this technology, the product development process will be revolutionized by removing the meshing bottleneck and substantially automating a significant portion of the design-analysis cycle. The feasibility of the proposed approach has already been demonstrated for a variety of analysis problems; please visit the home page of Intact Solutions at www.meshfree.com to download prototype 2D thermal solver software and to experiment with fully automated Internet analysis service.

Title:Rapid Thermal Modeling
Abstract:ThermoAnalytics proposes to create a streamlined process from CAD-to-thermal-model suitable for rapid prototyping and for virtual field-testing in synthetic natural environments. The use of thermal predictions in such applications has been restricted by the time required to build thermal models. Creating a mesh from geometry, adjusting the mesh to support thermal modeling, and model preprocessing can be painstaking and time-consuming. To achieve its goal, ThermoAnalytics will investigate innovative techniques to accelerate the thermal modeling process, and build a suite of tools to automate the most time-consuming modeling tasks. These tools address specific needs of designers and analysts: automated construction of meshes given CAD geometry, innovative "meshless" thermal solutions, and diagnostic and quick fix tools to repair meshes and models. ThermoAnalytics will also upgrade MuSES so that it is more tolerant of modeling defects, and to reduce model pre-processing time - specifically - the computation of radiation view factors. These improvements will alleviate user burden and reduce computational time. The resulting acceleration of the thermal modeling process will increase the size of the design space that can be explored during rapid design processes as well as permitting the introduction of new designs rapidly into real-time scene simulations.

Abstract:A hybrid power system for military vehicles, consisting of a battery/capacitor hybrid and a MEMS based integrated smart controller with wireless communication to the dashboard and to maintenance personnel is proposed. The hybrid increases available cranking capacity by utilizing the low current capacity of an automotive battery to charge a double layer capacitor bank which in turn is used to start the engine at the required high currents. The smart controller is based on Microns smart battery controller, which provides cell monitoring and status information of each cell inside a 12V automotive battery. The proposed technology includes a novel method for corrosion proof cell voltage access, the Micron OneWire system for a drastic reduction of the wire harness inside the battery, a novel charge algorithm to reduce gassing and a low temperature control system to prevent low temperature extremes. The control system is designed for integration in off-the-shelf automotive batteries and requires no changes to the battery case design of conventional batteries.

Title:Heavy Duty Vehicles Cold Starting System
Abstract:With the integration of new technologies and advanced electronics into military vehicles, there grows an increasing demand on electrical systems to sustain adequate energy during extended "silent watch" periods. Meanwhile, on-board storage systems must be capable of delivering sufficient electrical power to start heavy-duty engines under extreme cold temperatures. Conventional storage systems, including military lead-acid batteries, represent a compromise that is neither optimized for prolonged energy nor instantaneous power delivery. As a result, many heavy-duty vehicles in their present configurations will be unable to meet future silent watch and cold engine starting requirements. However, through the use of a dual-power distribution system, it is possible to optimize for both of these performance criteria simultaneously. Potential innovations include the integration of ultracapacitors to deliver maximum power during engine starting in conjunction with deep-cycle batteries that maximize the delivery of stored energy over extended periods of time. The objective of the proposed Phase I program is to demonstrate the feasibility of developing a dual-power distribution system for a heavy-duty military vehicle platform that outperforms convention implementations.

Title:Dual Electric Starting System fo Heavy Duty Vehicles Cold
Abstract:The advent of advanced electrical generation technologies has finally led to the development of novel devices that meet mission target goals for the next generation of high power and high energy density applications. Current battery systems in military vehicles are becoming increasingly unable to adequately support the full array of onboard electrical sensors as well as all weather vehicle operation. In response to this need, Mainstream proposes a dual electrical system comprised of Absorbed Glass Mat (AGM) batteries for maximum energy and ultracapacitors for maximum power. For a given DoD heavy duty vehicle, this Phase I effort will include (1) the investigation of key battery chemistries, ultracapacitor configurations, and fuel cell technologies and (2) the design of a complete dual electrical cold starting system for the given vehicle that maximizes both power and energy. In view of Mainstream's long-term commitment to the design and development of improved power production and conversion technologies and our past record of successful performance, we believe funding of this Phase I is warranted. The significant improvements in performance combined with the commercial potential and Mainstream's previous experience lead us to believe this Phase I effort will be highly successful.

Title:Use of Unmixed Combustion for Catalytic Cracking
Abstract:Highly compact lightweight autothermal reformers have been developed by several research groups which will allow the conversion of gasoline into hydrogen for use in portable fuel cell power systems. Excessive coke formation prevents these reformers from being used with logistics fuel. This problem would be solved by developing a portable catalytic cracker to convert logistics fuel into a fuel that resembled gasoline. Previous efforts to develop such a catalytic cracker have failed because 1) coke formation in the cracking process causes problems; 2) packed bed reactors conduct heat poorly, making it difficult to get enough heat into the reactor to supply the endothermic cracking reaction. Dr Lyon of EERGC has invented a new combustion technology called Unmixed Combustion. In application to Steam Reforming this technology has been shown to solve both the coking and heat input problems. EERGC Corporation proposes to use a combination of experimental and engineering design studies to develop an Unmixed Combustor/Catalytic Cracker; demonstrate that it converts logistics fuel into a cracked fuel with chemical composition and combustion properties similar to gasoline; identify the autothermal reformer most suitable for interfacing with the Unmixed Catalytic Cracker; and find the most thermally efficient way of doing so.

Title:JP-8 Gasifier and Pre-Reformer
Abstract:Precision Combustion, Inc. (PCI) proposes to develop a compact multi-fuel catalytic reactor based on the proprietary Microlithr technology for gasification and pre-reforming of up to 6 lb/hr (i.e. ~ 40 kWt) of liquid hydrocarbon logistic fuels, such as JP-8, diesel or Jet-A, without the need for external pre-heat or pre-vaporization. The size of the catalytic reactor is expected to be less than 30 in3 (0.5 liter) and weigh < 1 kg. The hydrogen rich gasified fuel mixture exiting the reactor can then be utilized in a downstream fuel cell or combustion device for clean and efficient energy generation. The pre-reformer will be capable of operating in either catalytic partial oxidation (CPOX) or autothermal reforming (ATR) mode. For the CPOX mode only fuel and air are supplied to the reactor, yet partial fuel conversion can be achieved. For the ATR mode small amounts of water will be recycled to the reformer, allowing achieving complete conversion of the fuel and higher efficiency of the reforming process. Therefore, the performance of the pre-reformer can be adjusted depending on the particular application. In this program the pre-reformer performance will be demonstrated and the requirements for the integrated system will be analyzed.

Title:Development of An Underarmor 10 Kilowatt Thermoelectric Generator Waste Heat Recovery System for Military Vehicles
Abstract:The development of a 10 kilowatt thermoelectric generator (TEG) waste heat recovery system has been identified as an approach to meet growing demand for on-board power combined with the requirement to reduce the thermal and noise signatures for emerging and future military vehicle platforms. Four elements are critical to the successful development of the TEG system: (1) increased efficiency of thermoelectric power generation systems, (2) increased power density, and (3) reduced cost, size and weight of resultant power generators. The last element is (4) a well-reasoned path forward, based on developmental experience and technical knowledge. BSST will develop the specified TEG system, using its advanced TE thermodynamic cycles in combination with high power density state-of-the-art thermoelectric materials to achieve the required efficiencies, size, weight and reduced cost. In its fundamental thermoelectrics R&D, BSST has demonstrated increases in power conversion efficiency of 2X compared to that of present high wattage systems, and size reduction in power generators of 4 - 6X using high power density state-of-the-art TE materials. Adding an APU function to this system is a task of only moderate difficulty, building on the basic elements of the TEG as discussed.

Title:Development of An Underarmor 10 Kilowatt Thermoelectric Generator Waste Heat Recovery System for Military Vehicles
Abstract:The proposed program will provide the preliminary design of a 10 kilowatt thermoelectric generator that can be used on the Army's Stryker and other similar vehicles. the proposed generator will directly convert energy in the exhaust of the Stryker's engine to electricity using advanced quantum well thermoelectric materials. It will also investigate the use of this generator as a separate APU by the addition of a logistic fuel burner and control system. The program will also investigate the applicability of this generator to other vehicles such as the FCS, Future Scout and LAV as well as the feasability of using a similar system on the exhaust of the Abrams Tank's gas turbine engine. The preliminary design of a quantum well based thermoelectric module for the 10 kW generator will be completed during Phase I. the eggcrate, element contacts, the necessary tooling, and film production for a prototype quantum well module for the 10 kW generator is proposed during the Phase I Option.

Title:Compact 10 kW TEG APU Using Exhausted Gas
Abstract:In this Phase I program, an innovative concept for a 10 kW thermoelectric generator (TEG) using high temperature exhaust gas will be developed. Analysis shows that more than 90 % of the total heat transfer resistance is at the gas heat exchangers attached to the hot and cold junctions of the TEG modules. The major innovation offered in this program is to use an innovative method to stack thermoelectric modules between layers of high performance heat transfer surfaces resulting in a highly compact design that meets the specified size requirements. Also, the enhanced heat transfer surface will reduce the aerodynamic noise and weight of the system. To achieve the desired power generation rate, a number of TEG modules and heat exchangers will be stacked. This requires efficient flow distribution of the exhaust gas and the ambient air through the stacks. This program will also study an innovative concept of the header to obtain a counter flow configuration. In Phase I, a high performance heat transfer surface geometry and header will be designed, and a sub-scaled system will be built and tested. The test results will include estimation of noise, size, weight, and the temperature of the exiting exhaust gas.

Title:An Advanced Water Filter for the Soldier
Abstract:Provision of clean drinking water poses a significant challenge to Army units in the field. Due to the quantity of water required and its substantial weight, soldiers can only carry a limited supply, and sustainment of soldiers through centralized resupply poses major logistical hurdles in many situations. Existing portable water filters do not meet the need to treat locally available water supplies for safe consumption. The proposed water filtration unit addresses the limitations in current filters. It will be lightweight and compact so that it can be carried by soldiers to purify water in the field and will meet the challenging EPA standards for microbiological purification. During Phase I, proof-of-principle filter hardware including housing, pump, and filtration media will be tested. Phase II will involve development of full prototype filter systems and extensive testing.

Title:Water Production for Tactical Systems
Abstract:Transforming the military into a sophisticated, lighter force able to mobilize quickly in response to crises around the world requires technological advancement in the production and distribution of drinking water. Recent Operation evaluations for both bottled water and bulk water use indicates that significant improvements in safety, cost, taste, distribution, and security are required to meet the transformation goal. WaterVisions International has developed improved drinking water purification technology which utilizes advanced composite materials. These materials incorporate only food-grade components (no pesticides), are inexpensive to manufacture, and highly scalable. System purification performance has been independently verified and meets EPA regulations. The technology can be embedded in soldier and vehicle systems, used to improve bulk water production, and can improve the taste of bulk stored water. Phase I objectives include evaluating microbiological and chemical purification efficiencies for prototype components designed to be embedded into tactile systems including the soldier system. Lightweight devices will be fabricated which provide 6-log reductions in bacteria, 4-log reductions in viruses, and 3-log reductions in cysts. Strong interest from commercialization partners who are currently evaluating composites for use in residential water purification applications guarantees that this effort will impact both military and civilian organizations.

Title:Robotic Mules Using Leg Pairs as Virtual Wheels
Abstract:Applied Minds, Inc. (AMI) will build a legged robotic vehicle by replacing the four wheels of a conventional vehicle with four leg pairs (such as those in bipedal walkers), effectively providing a set of very large diameter virtual wheels, resulting in a family of robotic legged mules with high ground clearance, high maneuverability, enhanced stability, and the ability to navigate very uneven terrain as well as narrow trails. Legged robots provide a practical solution for navigation on narrow trails but raise design and engineering challenges such as balance, stability, speed, and payload capacity. At the same time, when navigating uneven terrain, there are advantages to having wheels of very large diameter, both for rolling over surface irregularities, as well as to obtain a high clearance between the axle and the ground, but large wheels involve greater cost, greater weight, and greater power and mechanical demands on the vehicle, as well as decreased maneuverability. AMI have identified a solution to this problem by using leg pairs as virtual wheels in the design of a vehicle. By using leg pairs as a substitute for wheels in vehicle design, AMI's solution combines the advantages of legs and large wheels.

Abstract:A work plan is presented to perform surveys of components, manufacturing processes required and technologies anticipated for use in providing a preliminary design for a 4.4/8.8 kW (15,000/30,000 BTU/HR) multi-fuel fired forced air heating system. Existing products do not meet the requirements detailed in MIL-PRF-62550D. The work plan will outline the first phase of a program meant to culminate in a heating system that provides crew cab heat at low arctic temperatures for military tactical and commercial vehicles utilized in extreme environmental and rugged conditions. The proposed heating system that is developed from this proposal will contain self diagnostics, operating mode codes, component failure codes, system faults, error codes and data codes which are conspicuously displayed to assist in troubleshooting and repair. Furthermore, an analysis of candidate vehicle requirements and existing system capabilities will be investigated and documented. Finally, the proposed program will allow a fresh prospective to be taken concerning the potential for a Dual Air system to be compatible with current NBC protection considerations in over-pressurization of crew cabs.

Title:Lightweight Materials for the Expeditionary Fuel System (EFS)
Abstract:The Expeditiary Fuel System (EFS) concept was designed to be a modular fuel tank system capable of deployment aboard a multitude of ships, ground vehicles and aircraft. The EFS is comprised of individual tank modules mounted to a unique transport pallet. While the concept was successfully demonstrated in FY 2001, the prototype tanks were too heavy to meet requirements for production. The Marine Corps needs a system comprised of individual tank modules that can break down for transport aboard amphibious ships. The fuel tank modules must be affordable, lighter and more robust than the current aluminum EFS tank modules. Texas Research Institute Austin, Inc. proposes to develop a cost effective, lightweight, durable, modular, composite EFS fuel tank that will be man portable, easy to assemble and disassemble, and corrosion resistant, significantly reducing maintenance and repair costs. The composite EFS tank module will be constructed from composite materials that will meet all U.S. Navy shipboard requirements, operational loads and environmental exposures. The use of composite materials will provide a low cost, lightweight EFS tank module that will have a long, corrosion free, damage tolerant service life.

Title:Affordable Lightweight "Integral" Composite Material Design for The EFS Module (1000-305)
Abstract:Triton Systems Inc. proposes a lightweight, low-cost, composite material design to replace the current heavy aluminum system for the expeditionary fuel system (EFS) module. The composite EFS will be fire- retardant, corrosion resistant, and environmentally friendly. Triton will engineer and optimize the advanced thermoplastic or thermoset polymer matrix composite (PMC) material design for lightweight, rendering the EFS module man-portable. The lightweight EFS module will provide the Marine Corps with capability to efficiently conduct bulk liquid throughput and distribution on the battlefield. With its high strength-to-weight ratio, comparable stiffness, and energy absorption properties, engineered PMC offers significant potential for weight savings (>35%), over the current aluminum design. The composite EFS module will be fabricated using Triton's Controlled Resin Injection Molding Process (CRIMP), a modified version of Vacuum Assisted Resin Infusion Molding (VARIM) process, which is the most cost-effective integral manufacturing process. The process uses closed molds and is thereby environmentally friendly.

Title:Lightweight sandwich composites for improved thermal and acoustic performance
Abstract:In this phase I SBIR program, Advanced Ceramics Research, Inc. (ACR) proposes the development of an innovative, one-step co-curing fabrication process for sandwich composite structures with a flexible insulating material encapsulated by an fiberglass/epoxy face sheet for thermal and acoustic barrier applications. The flexible insulating material has excellent thermal and acoustic properties, is commercially available but its use has been limited due to the lack of structural integrity. The advantage of the proposed method is that in a stitched sandwich construction it can provide exceptional thermal and acoustic properties at half the thickness of current fiberglass/epoxy composites. ACR's patented water soluble tooling material will be used in the fabrication of sandwich panels with complex geometry. This provides the opportunity to make sandwich panels to fit any given profile further reducing size and weight. The composite panels can also be fabricated for modular construction to provide high repair/replaceablity at low cost.

Title:High Attenuation Thermal Barriers for the AAAV (MSC P1B16-327)
Abstract:Structural vibrations and heat produced by high output turbo-machinery can adversely impact the performance of nearby personnel and contribute to costly and premature failure of equipment within the AAAV. The product of the SBIR program outlined in this proposal is a lightweight composite structural enclosure designed to provide maximum acoustic attenuation and thermal shielding. The design concept proposed by Materials Sciences Corporation integrates two synergistic noise control technologies into a sandwich construction in which constituent materials, layering sequences, fiber architectures, and a structural geometry are tailored to maximize thermal shielding and transmission losses at a minimum weight. The feasibility of our integral acoustic attenuation concepts into low thermal conductivity panels will be demonstrated by designing, fabricating and testing five panel configurations to assess their performance relative to the AAAV performance goals.

Title:Passive Acoustic-Thermal Vacuum Insulation System (PATVIS)
Abstract:Performance requirements of the Advanced Amphibious Assault Vehicle (AAAV) have resulted in hot and/or noisy equipment inside the AAAV with sound levels over 120 dBA. Current methods are inadequate to allay these extreme conditions that present physical and operational hazards to Marines engaged in combat maneuvers. TAI is proposing a highly innovative concept to provide a new level of performance in combined thermal insulation and acoustic attenuation. Advances in the areas of thermal insulation and noise suppression are available through the use of vacuum insulation panel (VIP) technology. VIP has exceptionally low thermal conductivity resulting in thermal performance that exceeds AAAV requirements by as much as an order of magnitude. Because vacuum is the ultimate attenuator for sound, VIP provides a great potential for noise reduction. However, no study has been conducted to determine the effectiveness of VIP with respect to passive acoustic attenuation. TAI proposes to conduct such a study in this Phase I effort. Additionally, state-of-the-art viscoelastic materials can be packaged with VIP providing a synergistic combination of properties to achieve a solution for the AAAV.

Abstract:This proposal describes work efforts culminating in the design and eventual (Phase II) development of a prototype circuit card tester utilizing nanoscale sensors combined with laser and optical techniques to analyze circuit cards as an entire, complete system of components, circuit paths, and connectors rather than the sum of its individual parts. This revolutionary new approach has been made possible through the development of nanotechnology-based devices that can sense characteristics and changes at the molecular level, lending itself to the detection of entire classes of anomalies and failures that are not detectable using currently available automatic or other test equipment currently performing end-to-end diagnostic testing of individual signal parameters. These characteristics include degraded operational performance resulting from the aging of components as well as from corrosion, wear, stress, and other effects that may accumulate in the field. Our approach focuses on the development of a small footprint, man-portable lightweight system capable of being deployed via Humvee or remotely controlled ground or air vehicle to remote locations.

Title:Microscopic Damage Detection and Remaining Life Assessment of Printed Circuit Boards
Abstract:Field inspection of printed circuit boards (PCB), and assessment of their condition is critical for the readiness of military equipment. A new technology is needed that is portable and able to inspect PCBs, yet can perform sophisticated characterization of defects, and predict the remaining life of the electronics. The technology proposed by RMD could revolutionize the nondestructive evaluation (NDE) of PCBs and circuit components using inspection at the microscopic level to predict aging effects in PCBs. The technology is based on the use of a two-dimensional, high density array of microscopic MR (magnetoresistance) sensors for detection and mapping of both induced magnetic fields, and electric currents in PCBs and components. Analysis of the magnetic fields allows detection and imaging, at the microscopic level, of parameters such as electrical continuity, trace thinning, short circuits, and aging effects. The defects will be mapped and imaged in three-dimensional space so that the localized electrical parameters can be correlated with the nature and severity of the defect. RMD has assembled a team with the technical expertise, and experience to successfully develop the proposed technology. When fully realized, the new technology will detect defective circuitry, and analyze the reliability of critical DoD systems.

Title:Demonstration of a Portable Water Purification Device for the USMC
Abstract:A lightweight portable water purification device has been long sought by the US military. Mainstream has been hard at developing such a lightweight purification device since 1989, and has finally developed the configuration for a small portable device that will meet or exceed all the performance requirements of this USMC solicitation. This device, which uses a unique and patent-pending configuration, has already been designed by Mainstream and is discussed in this proposal. At 24 ounces dry-weight, this device can produce 1.5 liters of purified water in as little as 45 seconds. Cleaning is simple and straightforward. Phase I includes the fabrication and demonstration testing of this lightweight water purification device, which includes a 1.5 liter water storage capacity. Mainstream has been developing this technology for many years and we will continue to put our own Internal Research and Development funds into this project, because of the tremendous commercial potential for this technology. Phase I will allow a full demonstration of the concept's feasibility, and provide performance comparisons to alternative approaches. The Phase II effort will address DoD field testing, and prototype refinements for an actual USMC application.

Title:Man Portable Water Purification System
Abstract:In today's military, Marines must be highly mobile and carry all necessary equipment and supplies with them. A major limitation to mobility is the need to carry fresh water. An individual Marine must carry 12 to 24 pounds of water for each day they will be in the field without re-supply. It would be far better to be able to purify locally-available water, but no technology exists that will allow Marines on the battlefield to purify water in every environment. Existing, commercially-available water purification devices can readily handle large particles, bacteria, protozoan cysts and viruses, but currently there are no man portable systems for purifying brackish or salt water. In this proposal TDA Research, Inc. (TDA) will build a portable water purification system that includes desalination. The overall Phase I work plan is to build a prototype system, and then test its desalination capacity. From this prototype system we will be able to identify the advantage of desalination process and address the problems. We will do an engineering analysis to analyze the cost and performance of the system and allow us to design and build improved systems in Phase II.

Title:Arrayed, Wide Bandgap Semiconductor Based High Intensity LED for Area Denial
Abstract:Nanohmics proposes to develop a compact, efficient, high luminous intensity strobe light that emits in the 520 to 550 nm spectral range using gallium nitride (GaN) emitters. The design will be developed around an array of GaN surface mount chips for a 180 degree illumination pattern of light luminous intensities capable of temporarily disabling or disorienting potential adversaries (i.e. flashblinding). Nanohmics will also investigate the use of broad area emission from optically doped aluminum nitride as a down converter to optimize the emission wavelength for optimal eye sensitivity. The system will operate from rechargeable batteries, contain embedded circuits for variable frequency pulse generation, and an integrated radio-frequency link for remote programming and reporting of individual strobe systems. All strobe systems could then be operated from a single control unit for wide area coverage. Systems can be strategically placed to maximize probability of disabling the target(s). In Phase I, Nanohmics will determine optimal device properties and configurations. Based on this study, a prototype design of the system will be generated. During the Phase II, Nanohmics will take the most promising materials system and construct a prototype device optimized for Navy area denial requirements.

Title:Adaptive Noncoherent Dazzler Floodlight
Abstract:A noncoherent source of light is needed as a nonlethal weapon to disable opposing forces with minimal casualties. To address this need, Physical Optics Corporation (POC) proposes to develop a new Adaptive Dazzler Floodlight (ADF), based on a noncoherent compact source and a dazzler. ADF will deter opposing forces at controllable levels varying from repel to incapacitate. Its noncoherent eye-safe illumination will cause no permanent injury to personnel. In the ADF approach, the output power is controlled by switching on a variable number of light emitting diodes (LEDs), the outputs of which are collimated by nonimaging solid collimators. The ADF also includes a xenon arc lamp as a conventional floodlight whose output is collimated by an innovative POC omnidirectional collimator and directed by a conical mirror. The xenon lamp outputs the floodlight beam through the ring-shaped outer area of the ADF aperture, whose central area is occupied by the LED dazzler assembly. In Phase I, POC will demonstrate the feasibility of the ADF technology. In Phase II, an engineering prototype will be developed and tested.

Incorporation of low-cost, environmentally acceptable plant-based extracts that exhibit remarkable corrosion inhibition into the primer system will provide the required corrosion protection. Luna will demonstrate the performance properties of the coating system through the appropriate standardized military tests and in direct comparison to existing chromate-bearing military qualified products. Substantial cost and performance benefits with concomitant decreased environmental impact will be realized from the novel high performance system formulated to conform to existing logistical and operational requirements.

Abstract:The Advanced Amphibious Assault Vehicle (AAAV) is the United States Marine Corps' newest weapon system that moves three times faster and carries greater firepower than the current amphibian vehicle. The spectacular performance of the AAAV is due in part to the structural use of Aluminum alloy 2519-T87. Aluminum alloy 2519 is an Al-Cu alloy developed as a weldable material, and has ballistic penetration resistance superior to the previously used Al-Mg 5xxx series armor alloys, such as 5083. Unfortunately like other Al-Cu alloys (e.g. Al2024-T3 used in aircraft), alloy-2519 is highly susceptible to corrosion. Thus, high levels of corrosion protection are needed in order to minimize general corrosion, largely in the form of pitting and filliform corrosion and thereby minimize the AAAV's operating and support costs. TDA Research, Inc. (TDA) has developed a novel releasable corrosion inhibitor that offers exceptional protection for high strength Al-Cu alloys. TDA will incorporate these new corrosion inhibitors into a low-VOC epoxy and combine their use with the Navy's hexavalent-chromate-free trivalent chromium conversion coating to make a highly effective corrosion protection system.

Title:Non-Woven Textile Technologies
Abstract:The main objective of this proposal is to investigate the use of nonwoven textile composite fabrics in military applications such as battledress uniforms (BDU), chemical and biological agents protective uniforms (CBPU), tents, tarps, coverings, bags and other miscellaneous items where conventional woven and knitted fabrics are currently used. The opportunity is to create innovative and lightweight nonwoven composites that will enhance the functional performance of current military uniforms and other textile applications while retaining properties of wear, durability and printability at improved life cycle cost. The possibility of improving the current design of BDU to incorporate additional protection against chemical and biological agents while reducing the heat stress will also be explored. This phase I proposal will investigate the potential uses of various nonwoven textile technologies such as spunlace, spunbond, melt blown, ultrasonic-bonded and needle-punched for use in the US military. The nonwoven composite fabrics will be tested for functional properties such as durability, air permeability, printability and launderability.

Title:EPIC (Electromagnetic Personnel Interdiction Control)
Abstract:The Marine Corps has a requirement for a non-destructive stun weapon that would render a hostile war fighter ineffective for a period of time. There is significant political and military interest in such a capability. In addition, the ability to remotely incapacitate a human being without permanent damage would be a landmark event in the field of civil law enforcement. The desirability of waging bloodless war to counter threats to national security is virtually limitless since both military and civil authority could determine a priori when and if loss of human life is necessary. IVC proposes to investigate the use of beamed RF energy to excite and interrupt the normal process of human hearing and equilibrium. The focus will be in two areas. (1) Interruption of the mechanical transduction process by which sound and position (relative to gravity) are converted to messages that are processed by the brain. (2) Interruption of the chemical engine which sustains the proper operation of the nerve cells that respond to the mechanical transduction mechanisms referenced in item (1). Interruption of either or both of these processes has been clinically shown to produce complete disorientation and confusion. Second order effects would be extreme motion sickness.

Title:Remote Personnel Incapacitation System
Abstract:WaveBand Corporation proposes to develop a new class of remote Temporary Incapacitating Systems (TIS) particularly suitable for area denial to unfriendly crowds. The approach is based on a known phenomenon whose physical and physiological principles have been experimentally established. The proposed TIS has the advantages of: - Compact packaging. - Full perimeter coverage with dynamically controllable radius of the protected area. - Relatively low power consumption permitting autonomous battery powered operation. - Low probability of fatalities or permanent injuries. In the Phase I of this project WaveBand will demonstrate the feasibility of the proposed approach and will design its hardware implementation.

Title:Multi-Band Air Defense/Air Search Radar
Abstract:Multi-band phased array radar systems that contain solid-state transmitter sources and low-noise preamplifiers for transmission and reception are preferred over the conventional airborne radar antennas. The active array radar offers the advantages in the areas of power management and efficiency, reliability, signal reception, beam steering target detection and system performance. The current phased array radar design is narrow-band, very complex, expensive and less efficient. In addition, the size, power dissipation and the weight problems have inhibited the development of multi-band phased array antenna systems so far. This proposal describes the development of multi-band active radar system based on wide-band multi-functional antenna elements and very low loss, wide-band, and high power handling phase control circuits for beam scan. The new phase shifter design is based on micro-strip feed lines perturbed by the proximity of voltage controlled piezoelectric transducer (PET). The insertion loss of phase shifter is less than 1dB up to 20 GHz. The new active array radar design will have significant improvement in performance, size and efficiency.

Title:Multi-Band Air Defense/Air Search Radar
Abstract:Next generation radar systems will be required to perform multiple missions. For example tactical ground based systems will be called upon for supporting air defense with target identification and for air traffic control. Additionally the same system will be required to perform hostile weapons locating together with cueing of friendly weapons. It is essential that all of these missions be accomplished effectively with a high degree of performance and readiness. Providing the ability for the radar system to operate in more than a single frequency band enables realizing optimum multi-mission performance. Lower frequencies generally provide superior long range surveillance capabilities while higher frequencies excel for angular accuracy and target discrimination. Novel implementations for multi-band radar are essential to support system performance growth and system readiness, and to realize attractive total ownership costs. Sensis Corporation proposes to develop the technologies for realizing multi-band active phased array antennas for high mobility multi-mission radar systems. For Phase I of the proposed program, Sensis will leverage our expertise to formulate the dual-band radar system operational concept, architect the active phased array, establish key Transmit/Receive channel requirements, and derive an active array T/R building block concept.

Title:Enhancement and Optimization of a Lobed Mixer for AAAV
Abstract:CFDRC proposes to reduce the thermal and acoustic signatures of the AAAV engine exhaust with a minimal loss in installed engine performance by designing, optimizing and testing a passive, lobed mixer/ejector system. A design, analysis and test cycle based upon accurate and validated Computational Fluid Dynamics analyses, parametric design optimizations and detailed testing is proposed to reduce the detectable thermal and acoustic signatures. During Phase I our efforts will focus on isolated ejector analyses and tests that will be used to assess enhancements to the lobed mixer. This will be expanded during Phase II by optimization of the installed mixer system performance and signature reduction via consideration of flow features upstream and downstream of the mixer for various engine operating conditions and environments. The AAAV design currently incorporates an untested and uncharacterized, passive, lobed mixing device that conditions engine exhaust flow to reduce the thermal and acoustic signatures. The proposed work will characterize the existing system, and at completion of Phase II, result in an optimized design that reduces the thermal and acoustic signatures without significant impact on space, weight and power. CFDRC has applicable experience assisting GDLS in the design and analysis of such systems for other combat vehicles.

Title:Reduction of Ground Vehicle Observables Through Carbon Foam-Based Exhaust Treatment
Abstract:This project addresses the topic of Reduction of Ground Vehicle Observables. The use of carbon foam to reduce engine-related observables will be investigated. Carbon foam offers high specific thermal conductivity while providing better structural properties at elevated temperatures than traditional heat exchanger materials. Carbon foams also resist chemical and environmental corrosion without the need for additional coatings or treatments, making them well suited to abusive environments. Because of the foam's open-celled structure CFOAMr also has the potential to act as a filter for particulate matter. This study will address the reduction of three observables: heat, noise and particulate matter and the impact on cost, weight and performance. The Phase I effort will review design options and analyze their impact on observables, vehicle functionality and performance. Phase II work will construct a prototype to demonstrate the reduction of observables and will address future technological hurdles.
