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.

Abstract:The proposed effort is expected to result in a device that will maintain the charge on batteries that will be used in remote isolated munitions storage areas. 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%.

Title:Fiber Optic-Based Electronic Pointing Device for Indirect Fire Weapons
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.
