Title:6 Degree of Freedom RF Position Tracking for Virtual Reality Applications
Abstract:Facilities such as CAVE and GROTTO utilize rear projection displays to immerse the subject into the virtual scene Their success for scientific visualization and training has created the need for body tracking technology that does not exist. Current tracking systems based on magnetic sensors are only useable at short range and tracking can be significantly affected by nearby metallic objects. The proposed approach to whole body tracking for immersive environments is to utilize modulated RF tags with an inertial sensor. The tags are placed on the object whose motion is to be tracked. A stationary tracking receiver queries each tag by emitting a unique code. The tag responds by transmitting a dual frequency ranging waveform modulated by the attitude as provided by a solid state gyro. The phase difference between the two frequencies provides range which is processed to estimate tag position while demodulation provides attitude. Data is made available to a workstation where synchronization of subject position with projected video takes place. With recent interest in RF ID tags, wireless products and solid state gyroscopes there is an abundance of low cost RF ICs and subsystems which can be used to construct a demonstration prototype with little risk

Title:Improved Position Tracking System for Immersive Projection-Based Displays
Abstract:Spatially immersive displays such as the CAVET are increasingly gaining acceptance because they offer higher resolution and greater user comfort and realism than HMDs. A technology for accurate untethered tracking of several users within a large immersive display is needed to fully unlock their potential for interactive exploration. InterSense proposes to develop improved technology for tracking head and body position inside of immersive projection environments by extending our previously-demonstrated ConstellationT motion tracking system. ConstellationT uses innovative adaptive sensor fusion algorithms to optimally blend time-of-flight ultrasonic range measurements with angular rate and linear acceleration data from a proprietary micro-miniature inertial sensing device called the InertiaCubeT. The ConstellationT is a cost-effective, proven technology that delivers sub-centimeter accuracy over a scaleable tracking volume (up to the size of a whole building), with robustness superior to single-technology solutions. In the phase I research, we will analyze techniques for tracking multiple body parts of multiple users, and build a prototype system to demonstrate operation in a projective display environment. Our approach will provide precise, low-latency, 6-DOF tracking of multiple users in a spatially immersive display of any size with no sensitivity to metallic or electromagnetic interference and minimal user encumbrance or line-of-sight constraints.

Title:Low Parasitic Heterojunction Bipolar Power Transistors
Abstract:WiTech, in collaboration with UCSB, proposes to develop Gallium Nitride (GaN) based transferred substrate HBT transistor technology for highly linear and efficient broadband microwave power amplifier applications. WiTech has been actively developing GaN based materials technology for microwave power HEMTs. A transferred substrate HBT technology that minimizes the parasitic base-collector capacitance thereby resulting in very high fmax (> 400 GHz) transistors, has been demonstrated at UCSB. The ability to merge the aforementioned high performance technologies would lend WiTech a key advantage in developing GaN based transferred substrate HBTs. GaN based transferred substrate HBTs would enable an extremely low parasitic HBT technology capable of operating at very high power levels at microwave frequencies. A necessary feature of the transferred substrate technology is the presence of an etchable substrate. In order to facilitate this, WiTech proposes to develop the AlGaN/GaN based HBT structure on Silicon substrates. In the phase I contract, WiTech will investigate growth of GaN on Silicon and address the fabrication of the HBT base-emitter junction. The full-scale development of the HBT and circuit applications will be part of a Phase II effort. Transferred substrate AlGaN-GaN HBTs on Si substrates would combine the advantages of a low parasitic-high performance HBT technology, high power operation realizable from GaN based materials and the economies of scales of Silicon. This would make it possible to develop high power, broadband (1-5 GHz and 5-25 GHz), linear (3'rd order products 28 dB down) and efficient (> 60 %) amplifier modules.

Title:HTS Transmission Lines on Flexible Substrates for Digital Applications
Abstract:In several cryo-electronic technologies there is a need to transmit large amounts of RF digital signals from a low temperature end (4K) to a relatively higher temperature end (80K), with minimum signal attenuation, low cross-talk, and low static heat load. The primary objective of the Phase I effort is to explore the feasibility of developing high temperature superconducting (HTS) transmission lines on flexible substrates for digital applications, meeting the RF and heat load requirements. Flexible 3-mole% yttria stabilized zirconia (YSZ), with a unique combination of mechanical, thermal, RF and chemical properties will be used as the substrate. In-plane aligned YSZ buffer layers will be deposited by Ion beam assisted Pulsed Laser Deposition method. Subsequently deposited YBCO films will be patterned to form 50W transmission lines and their RF properties will be evaluated.

Title:W-Band Transmission Line and Rotary Joint
Abstract:Design is to carried out for a transmission system for a Naval Research Laboratory W-Band radar. This system is to convey high-power rf pulses from a gyroklystron amplifier within a radar van to a rotating antenna on the roof of the van. During Phase I, the mechanical layout for the entire transmission system will be designed. Two critical millimeter wave components have been identified that require detailed analysis, design and testing during Phase I. These components are the right-angle miter bend and the output mode converter. Low-power tests of these components are planned during Phase I. Successful tests with these components will allow the full electrical design of the transmission system to be completed during Phase I, for completion and high-power testing during Phase II.

Title:System Concept for ALR-67 Real-time Multi-Node Connectivity
Abstract:The ALR-67 Radar Warning Receiver (RWR) provides valuable data to its host aircraft and related onboard countermeasures systems. However, the data directly collected and analyzed by an ALR-67 in an action area could be further exploited by sharing it with an off-board SIGINT platform that could fuse it with data from other ALR-67s to provide enhanced Situational Awareness (SA) for the entire strike group. Specifically, data could be used to geolocate threat emitters if the data could be time tagged, [Time Of Arrival (TOA)] and provided along with aircraft GPS data to a central node for correlation with data from other ALR-67s intercepting the same emitter data. AVISYS, Incorporated proposes to develop a concept for modifying the ALR-67 RWR to provide its onboard processed data to a SIGINT fusion platform. The data could be transmitted through a high bandwidth distributed network such as the Navy's Cooperative Engagement Capability (CEC) The fusion platform could then perform the geolocation analysis using Time Difference of Arrival (TDOA)methods. The fusion platform could typically be an EP-3E or ES-3A operating in the vicinity of the action area, but beyond the lethal range of enemy weapons.

Abstract:A miniature, low-cost, and low-power ocean sensor system to be deployed on small Autonomous Underwater Vehicles (AUV's) for measuring and analyzing ocean surface waves will be designed and evaluated. Collection and automated onboard processing of AUV measured coastal wave data will enable validation of shallow water remote sensing wave estimation algorithms, validation and updating of shallow water wave generation and transformation models, and initialization of predictive models such as those for nearshore sediment transport and surf. Directional wave spectra will be obtained using data from a hull-mounted pressure sensor array with corrections for simultaneously measured AUV motion. An existing state-of-the-art AUV will be used to assure realistic design and enable collection of preliminary data.

Title:A Multispectral Fluorescence and Reflectance Probe for In-situ Characterization of Benthic Environments (7129-050)
Abstract:This project will investigate the feasibility of developing a compact, low-power, low-cost light probe to be used for remotely interrogating the fluorescence and reflectance properties of the sea floor and benthic marine organisms at a number of wavelengths. The resultant data would comprise the input to an automated bottom type classification algorithm. The point-by-point bottom classifications would in turn comprise the input to a statistical approach to characterization of the environment being surveyed. The system would be useable by divers or as a component on an autonomous or remotely operated underwater vehicle. The Phase I effort will include construction of a benchtop prototype of the primary sensor elements (light source and detectors), an experimental evaluation of the performance of the selected components, computer modeling of the implications of operating the sensor in the optically variable seawater environment, a computer evaluation of alternative schemes for processing and utilizing the sensor data stream, and a Phase II system design.

Title:Topological Matched Filtering for Active Sonar
Abstract:The most significant causes of poor detector performance are unrealistic and incomplete models for the true signal and noise statistics. Starting from first principles, we have developed a signal-processing model that incorporates more robust assumptions than is typical of published approaches for active sonar. Our new methods include robust estimators for removing reverberation and background noise to enhance detection of signals in difficult environments and a methodology for constructing a replica representation basis for classification of active sonar returns. An existing version of this processor has already demonstrated up to 10 dB deflection ratio gain on passive underwater ASW signals.

Title:Adaptive Data Fusion for Maritime Surveillance
Abstract:The 21st century Navy will need complete awareness of the surface and subsurface situations across a wide area of interest, in spite of the constraints of reduced budgets and manning levels, and the need for closer collaboration with other forces. To meet these new challenges, the fleet must rely on technology innovation, leveraging of existing programs, and consolidation of common functions across platforms. ORINCON's proposed research and development concentrates on the surveillance problem of high target density in a cluttered maritime environment. Our effort focuses on robust data fusion for ISR through algorithmic adaptation. Our goals are to incorporate adaptive control of the fusion process in the baseline Contact Management/Common Module architecture; to develop a fuzzy controller to select fusion algorithms based on changing problem context; and to demonstrate the resulting context-dependent dynamic adaptation of the fusion system. The immediate benefits will include improved tracking and classification performance, increased modularity and portability between platforms, and expanded interfaces to additional sensors. In a broader context, the Navy will experience payoffs in terms of leveraging of existing technology and improved performance that is widely applicable to surface-, subsurface- and land-based systems.

Title:GPS Bistatic Radar
Abstract:The Navy has a requirement to acquire and maintain situational awareness to facilitate potential actions in a littoral environment. Technology Service Corporation (TSC)and Radar Imaging Resources(RIR), in cooperation with NASA Langley Reserch Center (LaRC), will demonstrate that using GPS satellite signals as the illuminator for a bistatic radar system, will enable surveillance of the littoral environment. Since 1996, NASA LaRC has been crrrying out experiments using enhanced receivers to obtain GPS bistatic datra on sea conditions. These data contain evidence that ship targets are detectable using this bistatic technuque. During Phase I, TSC/RIR will work with NASA LaRC to collect and analyze data addressing the Navy littoral scenario. This activity will lead to a set of radar and platform requirements. TSC/RIR will define operational systems and a Proof-of-Concept radar system for Phase II development and test. The highly developed GPS receiver technology wil result in a low cost, very small package GPS Bistatic Radar receiver that can be mounted on a low observable UAV for covert surveillande in a littoral environment. The Phase I effort will also investigate the potential use of satellite receivers to obtain wide area surveillance over the open ocean.

Title:Environmental Data for Mine Warfare (16-H-98)
Abstract:In this project we will develop requirements and a detailed design for an Environmental Data Fusion for Mine Countermeasures (EDFMCM) system which will significantly improve the ability of Naval MCM forces to carry out their missions through the more effective use of available environmental data. EDFMCM will allow MCM planners and operators to (1) develop more effective MCM plans, (2) more accurately evaluate the effectiveness of MCM operations, and (3) more accurately evaluate the threat to shipping from mines which remain after MCM operations. We will concentrate on three key areas. These are (1) obtaining all of the environmental data which is relevant to MCM operations in the area of interest (AOI) with minimal operator interaction, and presenting it to the operator in an easily understood manner, (2) determining the variability and reliability of the available environmental data, using this variability to alert the MCM planner/operator to deficiencies in the data, and developing plans for obtaining additional environmental data in the AOI using the limited resources available to the MCM commander, and (3) analyzing the relevant environmental data, combined with both exercise and real-world operational MCM data, to discover the relationships between environmental factors and MCM effectiveness.

Title:Mine Warfare Environmental Data Analysis and Fusion System (MEDAFS)
Abstract:Mine Warfare and Mine Countermeasure decision-makers have few in-situ observations, infrequent remotely sensed images with course resolution, and a limited ability to synthesize the different types of information into one analysis. Limited datasets do not provide warfighters with a thorough understanding of the littoral environment necessary to make accurate decisions. The overall objective of this proposal is to develop the Mine Warfare Environmental Data Analysis and Fusion System (MEDAFS). This system will receive different types of environmental data (in-situ and remotely sensed), organize and integrate the data through Geographical Information Systems (GIS), fuse the data and analysis into a relational database and disseminate the information. Phase I Objectives - Design the laboratory necessary to create, test, and evaluate MEDAFS. Determine the data collection systems to be used in PHASE II where in-situ systems might include HF Radar, buoys, in-situ atmospheric and oceanographic packages; remotely sensed data might include ocean color systems (SeaWifs), NOAA polar orbiters (AVHRR), scatterometers (ERS), altimeters (GFO) and sea-surface microwave imagers. Modify Ocean Technologies' existing GIS software to receive, organize, and integrate the data collected within the laboratory. Design new methods for packaging the data and analysis together to disseminate to shipboard tactical decision aids.

Title:Vacuum Attachment Mechanism
Abstract:Attaching objects quickly, quietly, reliably and securely underwater is required for various operations by Navy Divers. To present most of these objects have been attached to surfaces magnetically. Magnets can be detected and removed, redeeming an operation unsuccessful. Various other methods have been explored, but the harsh environmental conditions have limited approaches such as adhesives. The concept proposed here attaches mechanically to ill prepared surfaces. No adhesive and surface treatment is required. The device can attach to non-ferrous surfaces. The device utilizes a vacuum not unlike the system used by an octopus. This ensures reliable, quiet and secure attachment to any surface.

Title:Development of Catalysts for Unmixed Reforming
Abstract:Since PEM fuel cells are much more efficient than motor generators, their use by U.S. Navy ships would greatly improve fuel economy. Use of fuel cells would also allow power to be generated where needed throughout the ship, eliminating the vulnerability of a central electrical power generator. Since fuel cells run on hydrogen, a process is needed to convert diesel (or other liquid fuel) to hydrogen. EER has been developing such a process, Unmixed Reforming, but to make the process fully satisfactory for use by the U.S. Navy, an improved catalyst is needed. The research proposed herewith will develop that improved catalyst.

Title:A Novel Hydrogen Generation System
Abstract:TDA Research, Inc. (TDA) proposes a Novel Hydrogen Generation System (NHGS) to meet Navy requirements for reliable fuel cell generated power produced by low temperature fuel cells operating on high sulfur (1% sulfur, wt) logistic fuel. TDA's NHGS will steam reform logistics fuel into a gas stream which contains >90% H2 dry basis, less than 1 ppmv sulfur and less than 0.1 ppmv carbon monoxide (CO). TDA's NHGS operates with a very high efficiency. This effect is due to the design of the novel steam reformer, which is the key research item in Phase I. The novel steam reformer provides the endothermic heat of steam reforming and at the same time minimizes the quantity of steam required for steam reforming while operating at temperatures where stainless steel components can be used. All other components in the system have been used commercially. We anticipate that over 70% of the lower heating value of the logistics fuel can be consumed as hydrogen in the fuel cell to generate power, including the losses from 1) purging the fuel cell of non-reactive gases, 2) reforming the logistics fuel, 3) generating steam, and 4) the heat content of the exhaust products.

Title:Novel Perfluoro-coatings for Enhanced Fouling Release
Abstract:Heat exchanger seawater inlet pipes and heat exchanger face plates of ships and submarines are susceptible to biofilm formation and growth reducing heat transfer performance. Current remedies include enviromentally harmfull chlorinations and high pressure flushing which is expensive and can damage equipment. Low surface energy, solution processable fluoropolymers offer a viable solution against seawater biofouling. Compact Membrane Systems, Inc.'s organophobicity coupled with an enhanced primer system and solution processability to allow for excellent adhesion. Additionally, these fluroopolymers are abrasion resistant, have excellent tensile strengh, as well as have solubility in selected solvent systems to allow for smooth, ultra thin in situ couatings. These materials show excellent resistance to biological fluids minimizing fouling while the low surface energy allows for excellent fouling release. Phase I activities include coating of metallic substrates and testing for (1) adhesion and continued toughness with immersion, (2) chemical stability and low surface wettability, and (3) biofilm growth and ease of removal. Objectives of Phase I work include the demonstration of good adhesion to metallic substrates, easier removal of foulants, compared to commercial silicones, and maintaining hydrophobicity and chemical stability in seawater.

Title:Hybrid Epoxy Resins Based on Silsesquioxane Cubes and Polydimethylsiloxanes for Use as Fouling Release Coatings on Inlet Side Heat Exchangers
Abstract:The Navy has identified a need for new environmentally friendly polymeric coating materials which possess high mechanical strength, high adhesion to substrates, and resistance to the surface build up of marine organisms. We propose the use of hybrid organic/inorganic epoxy thermosets based on silsesquioxane cubes ([(RO)SiO1.5]8, where R is an epoxy terminated organic group) in combination with amine-terminated polydimethylsiloxane hardeners as fouling release coatings on inlet side heat exchangers. Such hybrids would combine the demonstrated resistance of polydimethylsiloxanes to marine fouling organism with the direct incorporation of robust (SiO1.5)8 clusters into the polymer backbone, resulting in high thermal and chemical stability, low organic content, high mechanical strength, and excellent adhesion to a variety of substrates. Our objective for Phase I is to demonstrate that these advanced coatings can be easily fabricated using epoxy-terminated silsesquioxane resins and amine-terminated poly(dimethylsiloxane) hardeners and that they possess the desired physical properties. To achieve this we will 1) study the curing behavior of silsesquioxane resins with amine-terminated poly(dimethylsiloxane) of various molecular weight, 2) prepare a library of thermoset thin films with varied compositions, 3) measure their contact angle, adhesive strength, and hardness and 4) vary sample properties with the inclusion of commercial resins and hardeners. In Phase II we will further optimize the thermoset formulations, determine their long term stability in water, and fully assess their resistance to marine organisms.

Title:Development of Lattice Block Material as an Ultra-Light Structural Steel Fabrication Technology Technique
Abstract:The objective of the proposed work is to develop Lattice Block Material (LBM) as a cost effective fabrication technology for ultra-light steel structures. Specifically, JAMCORP proposes to develop manufacturing methods for producing LBM with densities less than 50% that of the bulk alloy. Lattice Block Materials are a new class of materials which make use of the well understood principles of trusses and space frames. These principles are applied at a size previously thought to be impractical for manufacturing. JAMCORP has successfully developed and demonstrated a manufacturing process to produce components having unusually high strength to weight ratios. The physical properties of LBM, such as temperature resistance and hardness, closely reflect the physical properties of the parent material whether it be a metal, an alloy, or a polymer. Cost-effective LBM manufacturing will enable significant reductions in structural component weight. Analysis indicates that hundreds to thousands of pounds could be eliminated from military and commercial naval craft if LBMs were used to replace solid structural components. Weight reductions directly increase maneuverability, range, and fuel efficiency.

Title:Ultra-Light Structural Steel From Metal Foams
Abstract:The objective of this proposed effort is to develop cost-effective fabrication technology for ultra-light steel structures using metal foam technology. Ultra-light metals, materials with densities less than 50 % that of bulk alloys offer significant structural advantages in terms of compressive strength- and stiffness-to-weight ratios for both military and commercial structures. Such materials have also been found to offer excellent crash protection, flame retardation, vibration damping and blast protection. UltraClad Corporation intends to build upon steel metal foam technology developed at Fraunhofer Institute which have been shown to offer promise in meeting program objectives. In Phase I concepts for low cost fabrication/manufacturing like Hot isostatic pressing (HIP), P/M techniques, and foaming additions such as strontium carbonate and carbon will be evaluated as candidate technologies. In Phase II a material mechanical and physical property data base sufficient for engineering design studies will be developed, and methods identified in Phase I for joining ultra-light steel materials and fabricating engineering structures will be demonstrated.

Title:Low Cost Grating Based Laser Sensor
Abstract:OPTRA,proposes to develop a low-cost laser sensor for recording illumination events during flight. The proposed sensor uses a diffraction grating, a CCD array, a fast photodiode, and signal processing electronics to extract and record illumination power, wavelength, pulse length, pulse repetition frequency, and event duration. The sensor possesses a wide two-dimensional field of coverage that is able to distinguish illumination from multiple locations as well as multiple wavelength sources. The sensor operates across the visible to mid Infrared with high resolution and uses low-noise electronics to achieve high bandwidth with large dynamic range. All the elements of the sensor are commerically off the shelf, low-costing parts that are mounted in a compact package. The sensor runs off of battery power and saves illumination event information in memory for post-mission downloading and processing on a personal computer. OPTRA will demonstrate the feasibility of the proposed laser sensor by designing a breadboard prototype and performed a detailed analysis.

Title:Frozen Platelets
Abstract:The long-term objectives of this research are the development for widespread use of closed, sterile, inexpensive disposable sets and their automated control systems for rapidly thawing and washing frozen platelets. The benefits in health care are a greatly extended storage time for frozen platelets compared to room temperature storage; a major reduction in the risks and incidence of bacterial growth in stored platelets; the removal of toxic cryoprotectants; a decrease in platelet damage during storage; the decrease in outdating during storage; and the improved logistics of platelet collection and administration. The use of unique hollow fiber counterflow fluid exchangers and automated control systems provide the potential for substantial technological innovation and low costs. The proposed research will evaluate the feasibility of this technical approach by the fabrication and testing of disposable sets actuated by automatic programmable control systems. In vitro testing with human platelets will permit comparisons between the proposed new methods, devices, and solutions and those reported in the literature or used currently.

Title:Low Cost Lightweight Rhenium Components
Abstract:Rhenium has been demonstrated to be the ideal material for construction of structures exposed to high temperature propellant exhausts, including divert systems, rocket motor throats, and gun tubes. Unfortunately, rhenium has three drawbacks, consisting of high cost, poor fabricability, and high density/weight. The proposed program will utilize commercially developed cermet technology to produce rhenium structures having high erosion and thermal resistance with a >50% reduction in cost and weight. Specifically, the proposed program will demonstrate the application of rhenium coatings to ceramic and metallic particles, which will then be fabricated into tailorable components using press and sinter or powder forging techniques. The resultant structure will consist of a continuous network of rhenium as the minor phase (roughly 30 v%), reinforced with a discreet distribution of ceramic or lower cost metallic phase. This technology is currently used for abrasives, syntactic foam, composite, and cutting tool manufacture. The proposed program would fabricate, characterize, and test in a subscale rocket engine, a series of rhenium cermets having a distribution of thermal conductivities and heat capacities, enabling the tailoring of rocket and gun components for naval applications.

Title:Ship's Weapons Connectorless Interface
Abstract:Connectorless interfaces for shipboard weapons would improve supportability and maintainability by reducing requirements to constrained access areas and provide corrosion avoidance/reduction. Connectors are often damaged during weapon/store transportation and handling, easily corrode in the ship environment, and complicate maintenance tasks required during removal, repair, and installation. The SITE team proposes to apply commercial-off-the-shelf (COTS) technologies in connectorless interfaces to ship weapons systems. The feasibility of various innovations in connectorless technology, based upon environment and location of existing weapon connectors, existing and future signal/data transfer, and available ships power will be examined and a preferred approach determined. Innovative technologies determined to be high risk for transmission/receipt of data signals will be demonstrated in Phase I. Phase II will propose an integrated approach to applying connectorless interfaces to eliminate all or a majority of weapons connectors for provision of data signals and power.

Title:Long-Life, High-Performance, Cost-Effective Refractory Metal Bore Surface Treatments for Gun Barrels and Missile Launch Tubes
Abstract:Gun barrel and missile launch tube wear limits the life and performance of air and surface weapons systems. NASWT requirements for enhanced accuracy, longer range, and higher delivered energy on target demand higher energy, higher temperature propellants and new projectile designs. These requirements accelerate gun barrel and missile launch tube wear and, in some cases, preclude the implementation of new propellants or projectiles. Alternatives have been proposed to inhibit wear. Potentially the simplest, most cost-effective such alternative is the addition of wear- and corrosion-resistant refractory metal bore surface treatments to existing barrels and tubes. The success of this approach has been limited to date due to high barrel length-to-diameter (L/D) ratios and related limitations of current processes for fabricating refractory metal liners within high L/D bores. These limitations are especially great for rifled barrels. To overcome these limitations, Ultramet proposes to use an innovative new low temperature chemical vapor deposition (CVD) process to apply refractory metals directly within conventional gun steel barrels without degrading or distorting the steel jacket. In Phase I, specific applications and goals will be identified and the feasibility of fabricating net-shape refractory metal bore surface treatments will be demonstrated.

Title:Wearable Language Translation System
Abstract:Mobile Translator Mission Statement: To develop a near real-time, two-way, mobile, lightweight, robust and low-cost multilingual language translation device that can be operated with minimal training in a hands-free manner. The object of this Phase I research effort is to investigate the scientific, technical and commercial merit and feasibility of the system described in the preceding mission statement. Specifically, the team will investigate design options for the mobile translator, identify potential applications, and select the best option to pursue in making the design a reality. Three technical areas will be investigated; the mobile computer platform, the operator interface, and the language translation software. The commercial feasibility of this design will also be investigated. This includes identifying potential applications, languages to be supported, cost, and user requirements such as acceptable system weight and battery life. By combining both the commercial and technical elements, a complete definition of a successful mobile, near real-time language translation device will be achieved. A prototype system will be developed and demonstrated and a final report written documenting the Phase I results and recommendations for follow-on research and development in Phase II. Options are included for incorporating additional language pairs into the system and application specific terminology.

Title:Innovative Heavy Fuel Compression Ignition Engine Designs
Abstract:The Navy has many tactical and operational missions that require equipment powered by lightweight, high output internal combustion engines, 5 to 150 BHP. Navy inventory of engine powered equipment in this size range is predominantly gasoline fueled. Department of Defense (DoD) has mandated future buys of engine powered equipment must have engines capable of burning heavy fuels: jet fuels and DFM (No. 2 diesel). The Navy wants fuel efficient, lightweight, high powered (1 lb/HP) compression ignition heavy fuel engines (HFE) 25 to 150 HP. These engines operate in a battlefield environment; stealth features are required. Operated by personnel with limited technical knowledge, engines must be reliable, simple to operate and maintain. No commercially available engine meets these specifications. AED Corp. will combine its developed heavy fuel burning spark-ignited, direct-injected controlled combustion engine technology with commercial electronic direct-injected gasoline and diesel engine technology to develop a compression ignition HFE operating on a precisely controlled dual combustion thermodynamic cycle limiting maximum cylinder pressure. HFE has applications for unmanned aircraft, generators, and other platforms throughout the military. Phase I base efforts: HFE base technologies will be analyzed and evaluated as applied to production 2- and 4-cycle high performance homogeneous charge engines. Two concept design layouts will be made around a 500 cc per cylinder engine. Following a design review, a concept test engine will be built. Phase I Option: the concept test engine will be installed on the dyno for heavy fuel test and evaluation.

Title:The Separate Process Diesel Engine
Abstract:Compression ignition engines have the highest potential for efficiency, greater mass processing, and torque per cycle of all positive displacement engines, yet they are RPM limited, which severely restricts their power to weight potential. Diesel engine operation allows extreme boosting as autoignition and pressures are controlled by injection. This same injection process which allows extreme mass processing and torque, limits the allowable RPMs, and severs the diesel engine's full potential. A new cycle has now been invented which promises to allow the compression ignition positive displacement engine to reach its full potential, thus achieving extreme mass processing, with RPMs limited only by rod integrity. Pressures can now be controlled mechanically rather than by injection allowing complete injection before top dead center. This cycle known as the Separate Process Diesel Cycle promises to surpass spark ignition engines, as to power to weight, while maintaining diesel efficiencies and emissions more characteristic of spark ignition engines. Military Separate Process Diesel (SPD) designs are modeled after the two stroke spark ignition engine which offers the highest power to weight potential of all positive displacement engines. The SPD engine cycle is carried out by the separation of the compression, combustion, and expansion processes in the SPD engine. This separation of processes allows separate process optimization as is seen in the turbine engine. The interaction between processors can be varied during operation, optimizing the SPD cycle through out the RPM ranges. This revolutionary technology is in step with the military's need for high power density compression ignition engines and promises to add to the U.S. military propulsion superiority as we move into the next century.

Title:Improved Formability of Aluminum Aircraft Skin Panels via Electromagnetic Forming
Abstract:IAP Research proposes to eliminate this costly preliminary heat treating step by using Electromagnetic Forming (EF), a high rate forming process to form aluminum aircraft skin panels in the T4 or T6 condition. EM forming uses electromagnetic forces generated on the aluminum workpiece by a closely coupled magnetic field coil to accelerate the aluminum sheet to velocities of nearly 200 m/s. Recent studies have shown that forming aluminum sheet at these velocities invokes a phenomena called "hyperplasticity". This phenomena has been observed in high rate sheet forming experiments with common aluminum alloys (6061). Plain strain extensions exceeding 70% have been recorded in aluminum alloys formed at room temperature. This exceeds the formability of steels and approached the extensions sought by the superplastic forming of aluminum alloys. IAP Research, Inc. proposes to exploit the "hyperplasticity" phenomena by developing the technology to form aircraft skin panels directly from a T4 or T6 condition using EM forming.

Title:Detonation Technology to Replace the Hard Chrome Plating
Abstract:The main goal of this project is to develop the new concept of gas detonation system to replace environmentally unfriendly Chrome Plating which is conventionally used in the industry. The environmentally friendly Thermal Spray Coatings provide excellent wear and corrosion resistance, but the highest quality coatings are sprayed by Gas Detonation Spraying Process, many with carbide containing materials. Analysis of coating properties and technology benefits of the detonation powder spraying ensure that Detonation Spraying Process can be successfully used to replace Chrome Plating. To meet the requirement of Navy to spray different powders (WC-Co, AL2O3, Cermet, etc.) on very thin aluminum plate, the development of new concept of detonation gas spraying process and equipment with efficient parameters and high deposition rate constitues the objective of this proposal. The substrate cooling system will be developed to keep the substrate temperature below 100 degrees C. To decide proper parameters and optimize the process, the required coatings are made on the heat treatable high strength Aluminum (7075-T6 and 7050-T7) substrate, and microstructure, stresses, diffusion, physical and mechanical properties of substrate will be evaluated. Also, the spraying parameters of different powder composition will be investigated to develop coating materials and technology to replace Chrome Plating.

Title:High performance hard carbon coatings for naval aircraft components
Abstract:EPA and OSHA regulations regarding the toxicity of the hazardous waste disposal products from surface treatments such as black oxide have spurred the quest for alternate coating process which meet or exceed their performance requirements. The challenge posed by this solicitation is to develop a low cost environment-friendly alternate finishing operation. The use of high performance carbon coatings that are hard, chemically inert and possess a low coefficient of friction has been proposed as the alternative. An innovative and economical process to produce this coating is also proposed. The coating is gray black in color and has intrinsic lubricity and exceptional wear and corrosion resistance properties and is galvanically neutral. While the coated surface is an excellent retainer of oil films, the surface will continue to perform very reliably even without the application of oil films. The low process temperature assures that the metallurgical properties and dimensional tolerances of the base material are retained. There are no effluents from the process and it is 100% environmentally clean. The process is simple and is expected to be highly scalable and economical.

Title:REPAIR OF CERAMIC MATRIX COMPOSITES FOR EXHAUST WASHED AIRFRAME STRUCTURES
Abstract:Nicalon/Blackglas CMC blastshields have been designed, fabricated, and tested for the AV-8B Harrier. They replace existing stainless steel blastshields that must be constantly repaired due to high thermal stresses and severe thermal acoustic loads. The improved CMC blastshields, however, cannot be introduced into the fleet until repair procedures have been developed and demonstrated for the CMC blastshield. The proposed program seeks to develop those repair procedures by combining the expertise of two leading organizations in this field. Materials Research & Design recently completed the first DOD program in repair of ceramic composites by successfully designing and demonstrating bonded, bolted, and reimpregnation repairs. Northrop-Grumman is the leading fabricator of Nicalon/Blackglas composites and they recently flight-tested the AV-8B blastshield that is the focus of this effort. The proposed Phase I program includes design, fabrication, and testing of repairs on Nicalon/Blackglas flat plates. A successful Phase I effort will provide a foundation for the Phase II effort which will address hat stiffened structures representative of the actual blastshield and thermoacoustic testing to simulate the in-service environment.

Title:Optical TCAS For UAVs
Abstract:In order to operate outside military ranges, UAVs need a means of achieving "see and avoid" at least equivalent to that achieved in manned aircraft. In this project, we propose to take low-cost visual image processing devices currently being developed by Mercedes-Benz as collision avoidance devices for the automotive market and adapt them for use in UAVs. We will use the analysis tools and encounter logic developed for the Traffic Alert and Collision Avoidance System (TCAS) to create an "Optical TCAS" that operates passively and can be installed at extremely low cost. We will use unique panospheric mirrors to achieve 360 degree coverage around the UAV without the need for complex and expansive scanning systems. Development and testing of this system will be facilitated through the use of Aurora's "Chiron" optionally piloted aircraft, which will allow continuous testing aboard an actual UAV operating in the National Airspace System. In Phase I, we will collect data on component performance and perform system trade studies. In Phase II, we will fabricate a prototype system, conduct ground tests, install the system Aurora's optionally piloted aircraft, the "Chiron," and fly actual test encounters to measure in-field effectiveness.

Title:Development/Integration of Low Cost, Light Weight See and Avoid Capability for Unmanned Aerial Vehicles
Abstract:To date, Remotely Operated Aircraft (ROAs) have been operated predominately by the Department of Defense and have been flown in special use airspace (SUA) and/or in accordance with the FAA (Order No. 7610.4) ROAs are now being operated increasingly outside of SUA for a variety of DoD and civilian tasks normally assigned to manned aircraft. Therefore, there exists a need to develop and integrate a "see and avoid" capability on current and future unmanned aerial vehicles (UAVs) that is equivalent to manned aircraft. Engineering 2000 addresses this requirement through this SBIR, titled: The Development / Integration of Low Cost, Light Weight "See and Avoid" capability for UAVs. LADAR/LIDAR technology will be used to detect obstacles within a full 360 degree sphere. Collision avoidance steering will be attained through an interface with the UAVs autopilot. Engineering 2000's experience with Fly-by-Light (FBL) technology will allow full optimization of benefits for improved UAV dispatchability and safety of flight. This concept will allow reduction of engineering and lowered first costs, production, maintenance and operating costs will also result.

Title:ISO-Lift
Abstract:The requirement exists to move ISO-containers short to medium distances over a variety of terrain and to position them in a variety of configurations. There are ISO-container `mobilizers' available. However, all the currently available systems suffer from significant limitations due to their size and weight, support required (in terms of material handling equipment), and the limited mobility that they actually impart. The efficiency of container based logistic operations could be significantly improved by the development of a system which: o could be fitted to an ISO-container by a small crew (1-2 people) and without mechanical assistance, and o would allow the container to be towed around a site, or short distance on road or cross-country, by any prime mover, and o allows the load to be positioned in any orientation relative to a ganged group of containers (that is, butted end-to-end, side-to-side, or whatever), and o when not in use takes up minimal storage space and requires no special support (such as a towing vehicle). Such a system could be called the ISO-Lift.

Title:Non-Hazardous Air Pollutants Rubber Cement
Abstract:Cements currently used to bond rubber to metal and rubber to rubber contain large amounts of hazardous volatile organic compounds (VOCs), including methyl ethyl ketone (MEK), toluene, and methyl isobutyl ketone (MIBK). These adhesives are essential to the bonding of gaskets, door seals, bumpers, heater boots, and other applications during Naval Aircraft maintenance and assembly operations. Environmental laws and regulations require the development of new non-hazardous cements that meet or exceed the performance requirements of MMM-A-121, MMM-A-122, and MMM-A-1617. Texas Research Institute Austin, Inc. proposes the formulation and testing of three new environmentally compliant, high performance cements. Two advanced water based and one high solids cement formulations will be investigated. Screening tests will be carried out to evaluate physical properties, and the best formulation will be optimized. The performance of this formulation will be compared to current specifications. Sample kits of the cement will be prepared, and the formulation will be submitted to NAVAIR for evaluation. This formulation will be modified based on sponsor feedback, and the final formulation will be submitted as a deliverable. TRI/Austin will team with an adhesive manufacturer and packager to set the stage for Phase III commercialization.

Title:GPS Interface Emulation for Flight Simulators
Abstract:The objective of this SBIR Phase I project is to develop a GPS interface emulation for flight simulators. The interface emulation allows a Control Display Navigation Unit (CDNU) with an actual aircraft Operational Flight Program (OFP), to function properly in a flight simulator environment as if the aircraft were really flying. In the flight simulator, the GPS navigation system will be replaced by a GPS interface emulation computer. The emulation computer receives real-time 6DOF trajectory data from the flight simulation computer and produces GPS measurement data by a GPS model. The GPS measurement data are then sent to CDNU through a MIL-STD-1553B data bus in a proper format and control protocol. The GPS interface emulation allows the aircraft OFP to be installed directly in the CDNU without modification. In this Phase I project, first, a GPS navigation system model and measurement simulation method is proposed and investigated. Next, the emulation computer configuration is proposed and designed. Then, the MIL-STD-1553B data bus hardware and driver program are designed and implemented. Finally, the CDNU interface emulation computer will be extended to include the interface emulation for an inertial navigation system (INS) or an integrated GPS/INS system, and thus achieve a more versatile interface emulation system for flight simulators and avionics system testing.

Title:Night-Vision Goggle Simulation/Stimulation
Abstract:Night-vision capability is a significant advantage for aviators performing missions with limited ambient illumination. However, scenes viewed with night-vision equipment under starlight illumination appear quite different from those same scenes when viewed under full sunlight illumination. These differences include brightness variations due to the nature of the illumination and the responsivity of the night-vision systems, anomalous artifacts such as haloing and loss of low-light contrast due to the presence of intense light sources, and a loss of effective visual acuity under conditions of very low light. As with other sophisticated technologies, a properly trained operator can effectively utilize a given system within the constraints of its performance limitations. Flight simulators are an example of effective training mechanisms that provide safe, cost-effective, and observable educational platforms. The difficulty in incorporating night-vision goggles (NVGs) into such systems is that current simulator display technology cannot sufficiently exercise or simulate the critical NVG characteristics described above. In this proposal, we describe an approach to emulate the full range of NVG characteristics for out-the-window simulators. Our approach augments existing simulators, uses actual NVG hardware (so that peripheral imagery, user work load, and night-vision phenomena are properly represented), and relies on existing image generators.

Title:Geographic Information System (GIS) Advancements for Mission Planning and Rehearsal
Abstract:The ARA team will analyze the capability of the GIS to meet the requirements for database development to support mission planning and rehearsal systems. Specifically, the team will investigate the family of GIS products from ESRI, which is a world leader in GIS software, as the baseline for GIS evaluation. The team will analyze and identify those GIS capabilities that meet the mission planning and rehearsal requirements, what requirements are not met, and what future GIS capabilities may satisfy the requirements. Once the GIS capabilities satisfying the requirements have been identified, then we will design and develop methodologies that will meet these needs. Some of the areas, already identified, which would greatly improve the capabilities for mission planning and rehearsal are as follows: direct and collateral bombing operation damage prediction and assessment, dynamic terrain blast effects, merging of data sources and OPFOR tactics to predict anti-aircraft and other threat locations, multi-spectral image and geometry input/capture and manipulation for large area databases with scalable complexity, and the creation of high resolution urban area databases. The analysis of the mission planning and rehearsal requirements performed by the ARA team may identify other areas that need to be developed. The Phase I Option portion of the proposal will consist of the ARA team developing a preliminary design for the implementation of the needed GIS enhancements.

Title:Process-Based Assessment and Training Support Tools
Abstract:The project by Micro Analysis & Design, Inc. presented in this proposal involves the design and demonstration of a Measure of Performance (MOP) based assessment system. The measurement approach is based on a probabilistic reasoning method using Bayesian networks. A set of three proof of concept demonstrations will be developed during Phase I. The demonstrations will evaluate the feasibility of using a Bayesian network assessment methodology, as the basis of (1) an MOP-based performance assessment and diagnosis tool, (2) long-term proficiency profiles for individuals and teams, and (3) an approach for assessing the effectiveness of training methods. Prototype instructor interfaces will be developed to (1) prompt the instructor/evaluator to enter observations into the automated assessment system, and (2) allow the instructor to inspect and link diagnostic information to the scenario context and the actions of other team members. Existing research and development efforts will be reviewed and a preliminary functional design framework will be developed for a process-based assessment and training support system. The proposed system would include: an automated performance assessment and diagnosis system, an integrated set of instructor support tools, a performance management database, and tools for analyzing the impact of training on combat readiness.

Title:Automatic Generation of Bump Map Textures
Abstract:There is an exploding demand for high fidelity 3D models in a variety of fields, both in the commercial and military sectors. Commercially available 3D rendering engines are able to meet these high fidelity 3D modeling requirements efficiently if they are given bump maps (which modulate the surface normals), as a supplement for the polygonal model. At the present time, however, the development of these bump map textures is a difficult and labor intensive activity. In an effort to reduce the cost of creating bump maps, the feasibility of applying automated techniques from photogrammetry and computer vision to the generation of bump map textures from photographic images will be investigated. A preliminary design will be developed for a software tool that will combine automated techniques with selected user input via a simple user interface. A working prototype will be developed to verify that acceptable levels of fidelity and automation can be achieved. Input from a variety of source data types will be investigated, including photo imagery and existing 3D scene databases. The generation of multiple levels of detail and smooth transitions between bump-maps and high fidelity 3D polygonal models will be addressed.

Abstract:A suite of software tools is proposed for the development of bump mapped texture patterns, including patterns of the surface normal vectors, shininess, and shininess strength. The tools are to be built as plug-ins to Adobe Photoshop (tm) beginning with adoption or modification of existing commercial tools for texture pattern generation including dehaze, color correction, perspective correction, autotiling, and sysnthesis. New tools are proposed for interactive generation of bump mapped textures from a single photograph and a materials catalog, from multiple photographs from a single perspective with varying light positioning, and from multiple photographs from a multiple perspectives with a single light position. Requirements for a library of patterns to be built with the tools is to be studied in conjunction with determination of the feasibility of the tool design.

Title:Exploitation of Target Scattering in Airborne Active ASW Systems.
Abstract:Active acoustic detection of underwater targets generally relies on reflection of the incoming sound energy. For a monostatic sonar attempting to detect a submarine target, the strongest signal return is a specular reflection from beam aspect. For a bistatic sonar, where the source and receiver are separated, the strongest return is a specular reflection. This SBIR proposes the exploitation of an additional signal path which is the result of acoustic scattering phenomena of targets. We believe this additional signal path will significantly increase the number of detection opportunities and will translate into increased mission effectiveness. The air ASW platform is the proposed commercial application for this technology. The air ASW platform is capable of deploying a distributed sonobuoy field which is ideally suited to take advantage of this signal. The existence of this signal path has been verified by the U.S. Navy. A few data samples of this scattering phenomena were obtained in one or two NAWC sea tests. This proposal provides an innovative approach to estimating the field performance improvement and the signal processing required to exploit this acoustic scattering phenomena.

Title:Exploitation of Target Scattering in Airborne ASW Systems
Abstract:Signal Systems Corporation proposes this research to improve current ASW system effectiveness by exploiting elastic wave re-radiation in multi-static sonars. We will use at-sea data, boundary element scattering models, existing echo detectors, advanced resonance extraction technologies and noise reduction techniques to conduct our research. The combination of these tools will demonstrate improvement in discriminating submarine echoes from other detections. In prior research, we have proven that our extraction technology can detect useful resonance phenomena in full-scale targets in mono-static geometries, but the reliable target to sensor ranges need to be increased. And, based on our work with acoustic scattering models, we believe that multi-static geometries will have stronger resonance amplitudes - thus motivating our proposed research. SSC also will pursue both coherent and incoherent sonar concepts, relying on noise and reverberation reduction techniques applicable to both types of sonars. In Phase I, we will process sonar echoes, comparing the resonance based classifier to existing data screening methods, as well as identify operational concepts compatible with resonant scattering theory and resonance extraction technology. These findings will be the foundation for a Phase II real time prototype system.

Title:Applying Evolutionary Computation to Route Planning
Abstract:Missile route planning has typically been performed by human or heuristics. As such, it has proven inefficient and unable to provide solutions to complex real-world problems. The aerial asset assignment problem (N missiles to M targets) is in the class of NP-complete problems, hence the difficulty in obtaining optimal solutions in a reasonable amount of computational time. Applicable constraints reduce the size of the search space but typically only by a few orders of magnitude. Significant improvements in automated aerial asset route planning can be achieved through the innovative combination of evolutionary computation with the Valuated State Space Approach for quantifying the mission to be accomplished. The inherent flexibility of this approach facilitates planning and replanning on-the-fly, and is extensible to other problem domains.

Title:Application of Product Line Engineering to Enhance Command and Control for Multiple Mission Planning for Multiple Precision Guided Munitions.
Abstract:By applying innovative systems engineering principles for a group of systems within a domain, generic architectures are defined and implemented that support commonality while allowing for variances among multiple systems. This developmental approach is the vehicle by which the Navy can integrate unmanned aerial vehicle operations with strike warfare on all platforms, air, sea, and land. This will directly lead to the capability to maximize the use of intelligence so that the resultant command and control system can more efficiently attack multiple targets with multiple weapons. Our experience in assisting in the implementation of product-line architectures across the government reduces the technical risk while enhancing the commercialization potential of the proposed effort. This proposed effort results in a common, modular, reconfigurable architecture for the Tactical Control System (TCS) and the Tactical Tomahawk Weapon Control System (TTWCS) with geometric reduction in development, deployment and maintenance costs for future releases of these systems. The common TTWCS/TCS can become the basis for future Navy Command & Control efforts that integrate advanced sensors with strike platforms. This effort includes refining the process and methodology of developing reconfigurable, modular, and adaptable architectures, which has tremendous commercialization potential throughout the public and private sectors.

Title:CMARS: Cruise Missile Autonomous Routing System
Abstract:The Gulf War demonstrated the changing nature of modern warfare. In modern warfare, a great deal of fire power is directed at a battle space compressed in space and time. Assets such as cruise missiles and aircraft are concentrated on a relatively small number of platforms. Thus, the complexity of mission planning is increased due to: (i) the trend towards jointness and (ii) using missiles and aircraft missile systems that are sophisticated in their capabilities. This complexity renders conventional mission planning systems inadequate to operational needs. Thus, the area of mission and route planning is fertile for the application of genetic algorithms and genetics based machine learning approaches. Phase I will demonstrate the application of a genetics based route planner for the multiple-mission, multiple-platforms scenario. The success of Phase I is largely assured by the previous work done by the Scientific Systems and Boeing in applying genetic algorithms to cruise missile route planning. Phase II will continue the Phase I development, and demonstrate and deliver an operational genetics based auto-router to the Navy. It will also develop a potential commercially viable Genetics-Based Machine Learning Toolbox for routing applications. In addition we will make Phase III plans for implementing a genetics based auto-router on the TLAM command and launch system.

Title:High Temperature Valve Research
Abstract:High speed airbreathing engines of the future will operate in the higher Mach regions of hypersonic flight (M>4) where aerodynamic heating is too great for conventional structural materials to survive without active cooling. The liquid fuels used in these engines must, therefore, have a good heat-of-combustion, and provide the necessary heat sink for an active cooling system. This program seeks to design, fabricate, and test the performance of a high temperature, high speed, liquid fuel control valve to Government performance requirements. In the valve approach proposed, the control of fuel flow rate is achieved by varying pintle tip axial position relative to a fixed orifice which in turn varies the flow area of the valve. Phase I will involve the design, fabrication, and testing of a prototype valve based on established high-performance Government requirements. Phase II will carry-out minimum size construction of both the fuel valve and its control electronics. A limited production run of five units will be fabricated, and multiple tests will be accomplished to document valve performance throughout the lot.

Title:Standard Telemedicine System Architecture (STSA)for shipboard Use.
Abstract:ImageView, Inc, will provide the Navy with an accelerated STSA based on its operational SeaMedTM commercial telemedicine system for both cruise lines and private yachts. SeaMedTM is a satellite-based service, which includes a 7 x 24 worldwide operations center connecting the ship's infirmary directly to emergency department physicians and specialists at Cedars-Sinai Medical Center in Los Angeles, thereby creating a virtual emergency room environment. By leveraging SeaMedTM and emerging technologies into the healthcare delivery system, ImageView will create a MIMS built upon patient-centric, secure, diagnostic quality multi-media medical records. Phase I will develop the engineering information necessary to provide a comprehensive definition of requirements and create a conceptual design for the STSA. Phase I Option will develop the first increment of schematics and requirements for the STSA, ensuring that system architecture is compatible with the MIMS being developed by NAVSEA/BUMED. An ongoing, and evolving conceptual design of STSA will be initiated supporting Phase II prototyping. Design elements from the LPD 17 will be examined, in conjunction with information from both the LPD 17 shipbuilder, Avondale, and the SWAN developer, Raytheon to create an LXX Theme Ship STSA conceptual design. The LXX Medical Department IRD will be implemented as a guidance document for anticipating MIMS functionality requirements. ImageView intends to submit a Fast Track proposal for Phase II.

Title:Standard Telemedicine System Architecture (STSA) for Shipboard Use
Abstract:The benefit of and need for Telemedicine in the Naval fleet has been clearly demonstrated by various studies done to date. However, practical implementation which provide an appropriate level of patient care without requiring dramatically more communications bandwidth than is available to the shipboard medical department have not existed, thus far. Here in this multiphase SBIR, ViaSat is proposing to design, build and test a system that can solve this problem. This system uses an innovative communications design to allow the use of commercial telemedicine components, but requires dramatically less shipboard bandwidth. Since this system is based on IP protocol, it will integrate seamlessly with present and planned shipboard and WAN systems. Because of its many advantages, this system has the capability to save time, money and lives.

Title:A Cogntive Learning Architecture for Shipboard Systems (CLASS)
Abstract:The Navy has embarked on an ambitious program to bring training "inside the lifelines", moving formerly land-based training to the operator's console on the ship. Embedded simulation-based training is the major technology being developed to achieve this goal, but simulation-based practice without adaptive and active instruction may be insufficient to meet the Navy's training needs in an increasingly complex tactical and geo-political environment. Advances in cognitive science have enabled the development of intelligent tutoring technology, in which trainees are given context-sensitive coaching and instruction in conjunction with simulated problem solving offers a potential solution to this problem. Technology develoments to make embedded simulation widely available (specifically the Battle Force Tactical Training or BFTT system) provide the means to leverage intelligent embedded utoring methods in a generalized way. CHI Systems proposes to develop a Cognitive Learning Architecture for Shipboard Systems (CLASS), using technology for tactically-oriented knowledge representation, cognitive diagnosis and student modeling that it has recently developed for a tactical embedded tutoring system. Phase I combines the technology and lessons learned from applying this new technology BFTT technology standards to develop a general CLASS architecture and software design, as well as a proof-concept demonstration.

Title:Advanced Techniques for Combat System Training
Abstract:Tight defense budgets and intense operational tempos have strained the military service's ability to maintain training readiness levels. These pressures make it imperative that new technologies and methodologies be harnessed to deliver training more efficiently and effectively. Intelligent Tutoring Systems (ITSs) are a training methodology that can help meet these new military training demands by delivering instruction that is individualized to the learning needs of the trainee. ITSs are software systems that apply advanced theories on the structure of human memory to training, and thus, are engineered to enhance learning retention by providing instruction that is compatible with those memory structures. Digital System Resources (DSR), Inc. proposes to provide an innovative, cost-effective, embedded ITS for the Cooperative Engagement Capability (CEC) operator. DSR further proposes investigating the feasibility of using this same architecture to develop a performance metrics and monitoring capability for use during the conduct of tactical scenarios. This will be accomplished by interfacing the ITS with the AEGIS Combat Training System (ACTS) or the Battle Force Tactical Training (BFTT) system. The proposed CEC ITS described here will result in increased learning and retention, shorter learning cycles, increased motivation, a precise real-time performance measurement capability, and ultimately, increased personnel readiness.

Title:Fiber Optic Compass
Abstract:A remotely monitored fiber optic sensor system which exceeds the Navy's performance requirements in a compact package will be demonstrated during Phase I. The orientation of the axis of the sensor head relative to the horizontal component of the earth's magnetic field is precisely determined using a novel optical readout scheme in conjunction with a conventional magnetic compass. In addition to magnetic heading, the system also measures the pitch of the sensor head. Compasses of this type, each connected to the dry-end signal conditioning unit by a single optical fiber, are suitable for mounting in a towed array cable to determine its trajectory in the ocean. The wet end of the system requires no electrical power. The cost of instrumenting an array cable is minimized because the sensor head is simple in design and contains only inexpensive components, and because many sensors can be multiplexed using a single light source.

Title:Fiber Optic Heading Sensor For Towed Arrays
Abstract:The objective of this SBIR project will be to develop an all fiber optic heading sensor for towed arrays which is affordable, accurate, immune to electromagnetic interference, free of electromagnetic emissions and suitable for a wide range of civilian commercial applications. The heading sensor will consist of three-axis, fiber-coupled magneto-optic sensors housed in a small, high pressure-tolerant cylinder. In Phase I, detection of the Earth's field direction to an accuracy of 0.1 degrees or better will be demonstrated. In Phase II, the magneto-optic sensors to an integrated form in which all components will be placed onto a single chip small enough to fit into the required form factor. In Phase III, an all optical heading sensor with the associated electronics package will be produced.

Title:Automated Shipboard Food Service
Abstract:Advanced Technology and Research Corporation (ATR) proposes to develop and demonstrate a prototype system approach for automation of shipboard food service operations. Phase I will baseline the conceptual design and evaluate the concept's feasibility. A Phase I Option will serve as a bridge to Phase II and result in the Preliminary Design of a prototype implementation. In Phase II, the prototype will be developed and installed in a shore facility for testing and evaluation. For Phase III, the prototype will be transitioned to a ship for at-sea testing and operational evaluation. The basic rapid prototyping approach will make maximum use of existing products and technologies from related or unrelated areas and adapt them for this application and the shipboard environment. Areas of risk to be addressed include acceptability of the food, automated storage/retrieval of chilled/frozen meal units within shipboard constraints, response times, cleanup & waste disposal, and underway replenishment.

Title:Advanced Technologies for Automated Ship Meal Preparation & Delivery
Abstract:The Aeptec Cook/Chill Automated Galley team has significant experience integrating Commercial Off the Shelf (COTS) equipment onto Navy ships. We have assembled a strong team which has expertise in all aspects of the problem to develop our Cook/Chill system concept. Aeptec has just completed the design, installation and testing of the first SHIPWIDE WIRELESS LAN SYSTEM on the USS THE SULLIVANS (DDG-68) and we are processing the PMS400 SHIPALT to add this capability to FFG's, DD's, DDG's, and CG's. Our team includes a commercial food service expert experienced with the implementation of Cook/Chill, a Robotics company, a company that is developing environmentally safe untensils, and engineers that have an extensive background in shipboard integration and the SHIPALT process. Our commercial partner, Hyperport Corporation, will take our Cook/Chill Automated Galley system to a worldwide market through their innovative theme park/commerce center concept that will revolutionize e-commerce. We will examine the current and evolving technology solutions available in industry for their applicability to a shipboard Automated Galley system architecture. Phase I will documents this approach and begin the planning for Phase II when our Cook/Chill Automated Galley recommendations will be implemented into a shipboard system prototype. Our Automated Galley will include a computer front panel that will enable sailors to order their meals remotely or on site. Our design will modify commercial Cook/Chill refrigerators and ovens that will be integrated with a Robotics system which will automate the meal preparation and delivery.

Title:Integrated Design Process
Abstract:The primary objective of the proposed effort is to demonstrate the feasibility of an integrated design process for the development, validation, accreditation, and integration of fluid dynamic and hydronumeric computer-based ship design tools. This will include the integration of tools that can be applied by the commercial maritime industry, as well as DOD ship and small boat design contractors, into a comprehensive design process. Existing ship design tools will be integrated at one common on-line site using an easily upgradable, open system architecture approach. While the current methodology provides adequate designs, it is a time consuming and expensive process due to the lack of design process integration. This process combines different design practices, each of which addresses different performance objectives, to produce an overall system design. For each process or design practice, there are different software codes and, in general, these different codes were not meant to interact with each other. This fragmentation of the current design process increases the time and cost of ship design, development, and analysis.

Title:Low-Cost Carbon-Phenolic Composites for Reentry Body Heatshields
Abstract:APD proposes to investigate the feasibility of introducing its textile preforming processes for advanced composite materials manufacturing into the processing cycle for carbon phenolic heatshields, to address the need identified by the Navy Strategic Systems Program Office to identify and quantify payoff of processing variations which reduce cost of carbon phenolic reentry body heatshields. Both braiding (2-Dimensional or 3-Dimensional) or net-shape knitting may provide solutions for a more cost effective production. In general textile preforming operations allow for a much more cost effective production of advanced composite structures. APD will use its integrated design for manufacturing approach to assess which textile preforming operation is most suitable. With textile preforming technologies it is also possible to create structures with a high toughness, by introducing through the thickness reinforcements. This may introduce means of controlling the ablative behaviour of the heatshield during reentry and provide for improved impact resistance. It is proposed to do a thorough review of the current material configuration and processing cycle and to start from there the creative process of finding alternative processing methods, including the composite impregnation and consolidation phases. APD will work with Thiokol Corporation, a.o. to assess the suitability of the RTM process. Cost estimations will be made for various alternative processing cycles, to assess which processing variations or alternatives should be further developed in phase II.

Title:Low-Cost Carbon Phenolic Composites For Reentry Body Heatshields
Abstract:This program proposes a fresh look at the tape-wrapped carbon-phenolic (TWCP) fabrication process used in the manufacture of reentry body heatshields with the objective of finding their variations to the existing processing or new processes which will result in significantly reduced costs. Since the TWCP process was developed in the 1970's, there have been significant advances in composite processing methodology such that large complex parts can be made near net shape by semi-automated techniques resulting in improved uniformity and reproducibility. Despite these advances, a new process has not been qualified for TWCP becuase of the high cost of qualification. The dwindling supply of qualified rayon fiber affords an excellent opportunity to develop a new SOTA process. This program will quantify cost reductions afforded by advances in fabrication technology to the existing process as wll as from alternatives and prioritize them on a cost/performance basis. The Phase I effort will assume low thermal conductivity PAN-based carbon fibers as rayon replacement materials. Phase I will produce a plan for Phase II, to evaluate high priority alternative heatshield fabrication process(es). This program will validate the cost reduction estimates and include hardware fabrication for test evaluation.

Title:Tethered Aerostat Communication Link Application
Abstract:The Phase I project effort will develop a rapidly deployable aerostat system capable of elevating communications relay equipment to an altitude of approximately 600 meters for the transmission and reception of voice and data information to U.S. Navy vessels in a logistic support mode. The aerostat system will supply the connectivity between the logistic support group and the sea-based end of a fiber optic cable leading to forces ashore. One of the aims of the study effort will be the design of an aerostat system which can be left unattended for a long period of time. The study will determine the aerostat design, power system, mooring platform and deployment methods for the aerostat system. In addition, computer simulations will be employed to determine the "red line" limits for the operation and survival of the aerostat system.

Title:A Modular Composite Pier Deck (MCPD) for the Navy's Hybrid Pier
Abstract:KCI will develop and compare a variety of designs for very large modular pultruded composite pier decking sections. KCI has considerable experience with design and fabrication of large composite panel structures. As part of a previous Phase II conducted for the Air Force, KCI designed and built what we believe to be the world's largest and most capable pultrusion machine. This machine is optimized specifically for fabrication of very low cost composite panels up to 10 feet wide. Because pultrusion is the least costly method for making constant cross section composite structures, the pier decking designs developed during this proposed program are expected to use that as the manufacturing process of choice. During Phase I we will develop several alternatives for deck concepts, each one involving a different combination of materials and geometry. Finite element analysis will be used to size each candidate to pier design loads. Manufacturing procedures will be conceptualized, and estimates for production cost of each option will be developed. KCI will also demonstrate the possibility of embedding fiber optic strain sensors in the composite structure during the pultrusion process in order to provide the ability for in-service health monitoring.
