Title:Development of a Regulated Transformer Rectifier Unit (RTRU) for the V-22 CV Requirement
Abstract:Modern US Navy aircraft as well as older aircraft currently being updated to today's avionic standards, contain avionics and ordinance equipment that require regulation of the 28VDC system. The V-22 platform utilizes three regulated AC/DC converters (CVs) to provide regulated DC power from the AC generator source. The presently used device uses a power topology that yields both a very complex device and electrical system. The current design provides a regulated DC output at the expense of reliability, cost, weight, electrical performance and aircraft system compatibility. Avionic Instruments Inc. offers to perform a Phase I SBIR feasibility study to verify that by utilizing a patented form of regulated transformer rectifier, the V-22 CV can be improved. Specifically, this technology will allow unit cost to be reduced to less than $ 15,000., overall weight to less than 25 lbs. and reliability to be increased by ten fold. A Line Conditioner-based AC/DC Converter (CV) is proposed that will, in addition to meeting SBIR objectives, provide TRU-like qualities such as high input power factor, low input current harmonics, high overload and short circuit capability. A reduced parts count enables the design to increase reliability and reduce cost. Avionic Instruments will examine potential semiconductor devices, new magnetic materials and novel thermal approaches to further enhance the design. Circuit models will be created and computer simulations performed to demonstrate comparative differences of various regulated converter topologies. In addition, a demonstration of the existing Line Conditioner-based CV topology will be provided to the Navy. A final report will be provided at the conclusion of Phase I.

Title:Develop Low Weight/Low Cost AC/DC Regulated Converter for V22 Applications
Abstract:We propose to apply our Power Node Control Center (PNCC) technology to develop a converter for the V22 application that meets the power quality, size, weight and cost requirements. The innovations in our concept are: (1) the use of Multi Functional Programmable Modules (MFPM) which are half bridge leg to perform the power factor correction, boost rectification on the input end, and the buck conversion on the output, (2) the use of Pulse Current Modulation to perform the power factor correction on the input, and (3) the use of plastic coated iron powder composite pot cores to form the chokes required for filtering which reduces the size and the cost of the filters. In Phase 1 of this effort, we propose to develop the concept and conduct bench type test to validate key concepts.

Title:Develop Low - Weight / Low-Cost AC/DC regulated Convertor for V22 applications
Abstract:This document describes Innovative Power Solutions (IPS) proposal to design a regulated converter for the V22 aircraft. This unit converts aircraft 115/200 VAC, 360 to 457 Hz, three phase power into a regulated 28.7± 0.3 VDC output. The objective is to meet the stringent power quality as well as the EMI and thermal requirements in a package that will conform to Boeing drawing 901-375-201 and not exceed 30 lbs. The goal is to offer the regulated converter, in production quantities, for less than $23,000. In order to meet these ambitious goals we intend to use a high switching frequency to help reduce the filter size. This will help reduce size and weight, as well as improve power quality. Additionally, improving efficiency will be a prime goal that will require help meet the thermal requirements of an aerospace application. Cooler operation will increase the reliability and will eliminate the need for extensive heat sinking, again reducing size and weight. Modular design will be used to cut production costs and improve product maintainability so that purchase cost and life cycle costs could be reduced.

Title:Failure Detection System for Composite Joints
Abstract:There is a need for a portable X-Ray System with appropriate software that can be used to document failure initiation and propagation on lap joints and joints with woven inserts. This system could be used to validate analytical and numerical failure analysis predictions. Additionally, the system could support Non-Destructive Evaluations on carriers, in repair depots, and in the field. The proposed portable X-Ray System, identified as "RX-BOND," makes use of the unique resolution and imaging advantages of Reverse X-Ray technology. Additionally, the system is capable of Computed Tomography (CT) and utilizes the information contained in the diffracted X-Rays to measure peel stresses in the bondline. This multimode operational capability combined with system portability and ruggedness is much beyond the current state of the art. The feasibility of the "RX-BOND" system will be investigated during the Phase-I Basic Program. Additional tasks in the Phase-I Option concentrate on the portability issue and on the identification of a bonded structure on a Navy platform which could benefit from RX-BOND technology. This information will be submitted as part of a Phase-II readiness report.

Title:New High Density Scintillator-Based X-ray Imaging System for Nondestructive Evaluation of Composite Structures
Abstract:The sophisticated new designs of multi-layer composites currently used in naval technology present a challenging problem of detecting integrity-reducing anomalies to assure safe and reliable operation. Microwave techniques are useful for NDT of these composites due to their penetrating power and sensitivity to changes associated with boundary conditions. However, microwave bending and surface polarization make it difficult to localize the detected defects. Conventional techniques such as ultrasound and infrared imaging do not provide the necessary resolution. Thus, a reliable technique to address this problem must be developed. Recent advances in 3-D x-ray imaging modalities have created excellent potential to successfully address this demanding application. The capabilities of these powerful instruments, however, are presently limited by the x-ray sensors available, which offer a tradeoff between the efficiency and the image resolution and limit the speed of operation. We propose to develop a novel x-ray imaging detector based on a new transparent optical ceramic scintillator to address these needs. The scintillator will be micro-pixelized to provide high detection efficiency without degrading the image quality. The scintillator will be integrated into a fast digital readout to form detector that will allow the full potential of advanced 3-D imaging modalities be realized.

Abstract:The objective of this Small Business Innovative Research project is to investigate and develop the capability for the selective depainting of Navy aircraft and the cleaning of precision instruments and equipment using semiconductor diode laser technology. This will be accomplished by first demonstrating in a laboratory environment, performing materials testing and cost analysis, and then designing a and testing a scale system for rapid depainting and cleaning of aircraft surfaces and components. It has been demonstrated that diode lasers offer the ability to selectively strip and clean coatings and soils in an efficient and cost-effective manner over other types of lasers and methods.

Title:ACIM Assisted Selective Depainting and Precision Cleaning of Delicate Surfaces
Abstract:Cavitation is ordinarily a chance-dominated process. Recent research in ACIM (Acoustic Coaxing Induced Microcavitation) promises to solve the long-standing problem of "controlling cavitation". Being able to control microcavitation enables one to solve formidable engineering problems. During this Phase I effort, we seek to evaluate the feasibility of using ACIM for selective depainting and precision cleaning of delicate surfaces. Such cleaning will be accomplished using only "SILENT SOUND and CLEAN WATER". No chemicals will be used. Acoustic microcavitation is brought about by low megahertz frequencies and involves micron size bubbles that last a few microseconds. During microcavitation the imploding cavities create intense energy densities at the implosion sites. Since these implosions are effective only at the thin surface layer, controlled microcavitation (ACIM) is ideal for cleaning surfaces without damaging the underlying substrate. ACIM assisted selective depainting and precision cleaning will be universal in application and effective on all substrate-paint/particulate combinations.

Title:Environmentally Compliant Self-Priming Aircraft Coatings
Abstract:A corrosion protection process for treating structural aluminum aircraft components is proposed which can simplify manufacturing and maintenance operations while dramatically reducing hazardous waste generation. The proposed research explores the feasibility of using an aqueous blend of surface oxide derivatizers and film-forming polymers with non-hazardous corrosion inhibitors to yield self-adherent, self-priming topcoats. The proposed primer/topcoat paint would exhibit better stability in the presence of inorganic corrosion inhibitors and yield coatings having significantly less permeability to water and ionic species than conventional waterborne coatings. The ability to form strongly adhered, durable barrier layers over structural metal alloys without the need for toxic chemical etchants and pigments or multiple coating applications would represent a significant advancement in corrosion engineering. The objective of the Phase I program is to identify candidate materials which meet the goals of low toxicity, simple application, adhesion promotion, and corrosion prevention. A novel combination of polymers and sol-gel precursors will be used to form stratified coatings to achieve optimum adhesion and corrosion inhibition. These formulations will be tested on common aircraft aluminum alloys for salt fog resistance and paint adhesion. Potentiodynamic electrochemical analysis will also be used to study the corrosion inhibiting mechanisms.

Title:Corrosion Inhibiting Fluoropolymer Film Wallpaper System for Aircraft
Abstract:Naval and Marine Corps aircraft suffer from pitting and crevice corrosion to a much higher degree than land based counterparts. Operation from air capable ships ensures that 7000 series aluminum alloys are exposed to the chloride ion from salty seawater spray and air. This aggressive corrosion environment increases: sailor maintenance demands, inspection requirements, and ultimately, total costs per flight hour. A logical solution to the corrosion problems on aircraft surfaces would result from application of a thin fluoropolymer wallpaper system with embedded revolutionary corrosion inhibiting features. One of the present drawbacks of applique technology is the inability to prevent the chloride ion from reaching the substrate where the applique is gouged, torn away, or along seams and edges. This research seeks to address these problems by incorporating an inhibitor that retards pitting, corrosion fatigue and stress corrosion cracking of aluminum alloys, into the applique or adhesive system. The goal of this proposal is to utilize the "Fluorogrip" method for surface modification of fluoropolymers and incorporate corrosion inhibitors directly into the film or pressure sensitive adhesive. The adhesive system to be used for this project will be tailored for near complete removal without solvents in cases where film replacement is required.

Title:Elastomeric Aircraft Primer with Non-chromate Corrosion Inhibitors
Abstract:The overall objective is the development of a non-chromate low VOC content primer that meets the requirements of the current flexible polyurethane (TT-P-2760) and earlier polysulfide (MIL-P-87112) aircraft primers. The primer is based on an epoxy-elastomer resin that forms a microscopic interpenetrating network on cure. The epoxy imparts strength, fluid resistance, and adhesion while the elastomer provides low temperature flexibility. The elastomer also acts as a reservoir for corrosion inhibitors and other functional components added to the primer. Chromate inhibitors will be replaced by new organic inhibitors that demonstrate comparable corrosion inhibition of Al 2024-T3 and Al 7075-T6. These inhibitors will partition into the elastomer and leach to active corrosion sites if the primer coating is damaged. In Phase I, primer formulations that exhibit the necessary flexural and corrosion resistant properties will be developed and characterized for ambient and low temperature flexibility, salt spray and filiform corrosion resistance. Collaboration with a coating manufacturer and aircraft company to conduct testing to appropriate Military and Federal standards is proposed. Phase II would involve refinement of primer formulations, address all aspects relevant to meeting Military Specifications and acceptance for use at depot facilities, as well as field-testing.

Title:Non-Chromated Flexible Primer
Abstract:Foster-Miller proposes to develop a flexible primer system for US Naval aircraft which meets/exceeds current military specifications (TT-P-2760) and exhibits enhanced delamination resistance and corrosion protection without the use of toxic chromates. Our approach combines three concepts to generate this next-generation primer: 1) incorporation of flexible segments into the primer which do not impact mechanical and solvent resistance properties, 2) incorporation of functional groups into the primer enabling chemical bonds to be formed across every interface, and 3) a non-chrome-containing corrosion inhibitor system that becomes active only at the onset of corrosion. The primer will be designed not to require any special equipment or procedures which would interfere with naval aircraft maintenance facility operations. Phase I will concentrate on proof of primer feasibility and preliminary corrosion studies, with full development of the corrosion inhibitor system deferred until Phase II. Primer formulations will be developed, tested and evaluated according to targeted performance specifications of TT-P-2760. The primer will be low VOC, have viscosities suitable for spray application, and be compatible with existing substrate pretreatments and topcoats. Samples of coated test panels will be submitted to the US Navy for independent evaluation.

Title:Innovative, Thermal and Environmental Barrier Coatings for Aircraft Exterior
Abstract:There is an ever-growing need for thermal and environmental barrier coatings for applications in aerospace and defense industries. Such coating of aircraft fuselage, supersonic aircraft fuel tanks, cryogenic containers and munitions packages not only reduces the need for elaborate safety back-up systems, but also cuts down on wastes. The minimum general requirements for TEBCs and associated materials are: (i) lightweight, (ii) minimum bulk, (iii) very low thermal conductivity, and (iv) radiation resistance. Other special requirements include fluid and humidity resistance, adherence, low gloss in visible wavelengths, and reasonable electrical conductivity. State-of-the-art coating technology employs multi-layer and multi-material(polyurethane elastomers or silicone binder in combination with ZnO or MgO or other ceramic insulations) configurations that must be improved for performance, life, and versatility. LoTEC, Inc. proposes to develop a cost-effective, advanced coating material system that is non-outgassing, non-flammable, and has superior thermal insulation, environmental resistance, radiation stability, and noise-reduction characteristics. Thermal spraying deposition, which is an environmentally-benign coating process in which a polymer powder is injected into a flame or plasma, will be used to apply the coating. Liquid crystal polymers (LCPs) will be used in conjunction with ceramic hollow microspheres (CHMs) to form the protective coating.

Title:Advanced Fullerene Thermal Protection for Exterior Aircraft Structures
Abstract:The proposed concept of advanced thermal barrier technology utilizes fullerenes and fullerene-based materials to create effective lightweight and environmentally safe thermal protection coatings on exterior aircraft structures exposed to high temperatures. Based on preliminary results, fullerenes were shown to have extremely low thermal conductivity and high emissivity along with low ablative rates and good ablation cooling properties. During the course of this Phase I project, MER will investigate thermal properties of fullerenes and fullerene-based materials in wider temperature ranges and develop apropriate techniques of applying fullerene coating onto the surface of aircraft components. The optimization of these parameters and procedures will be performed during anticipated Phase I programs.

Title:Design Assistant and Software Tools for System Identification and Adaptive Fault-Tolerant Control
Abstract:Significant advances have been made in the development of health monitoring and control algorithms that identify unmodeled dynamics and compensate for many classes of system failures. Yet, there is a general reluctance on the part of industry to employ these techniques in safety-critical production applications. Although many valid reasons exist, a primary source of resistance is the requirement that industry end-users abandon familiar design and certification practices to achieve safety and performance benefits for flight conditions that are rarely encountered (e.g., failures). The proposed work addresses many of the challenges associated with retrofitting existing flight control systems to provide engineers with an ability to compensate for airframe damage, sensor and actuator failures, effector impairments, and dangerous unmodeled dynamics. The approach leverages recent algorithmic advances in system identification, statistical change detection, and model validation to yield a simple (from the user's perspective) add-on system module that provides adaptation to the baseline controller only during a failure. To fully exploit the opportunity, a prototype software tool is envisioned that will allow automated development of custom add-on reconfiguration modules.

Title:Design Assistant and Software Tools for System Identification and Adaptive Fault-Tolerant Control of Fighter Aircraft
Abstract:Scientific Systems Company Inc. (SSCI) proposes to develop a systematic procedure for the design of algorithms and a toolbox for System Identification (SI), Health Monitoring (HM), Failure Detection and Identification (FDI), and Adaptive Reconfigurable Control (ARC) algorithms for F/A-18 aircraft. In particular, in Phase I we will carry out the following tasks: (i) Problem formulation and acquisition of linearized F/A-18 models and flight test data for flutter identification; (ii) Apply Deterministic Stochastic Realization Algorithm (DSRA) and Global Maximum Likelihood Estimation (GMLE) algorithms to flight data of F/A-18 aircraft; (iii) Determine the sensitivity of the system to different failures; (iv) Quantify the available control input redundancy in terms of the control authority required to accommodate different failures; (v) Design integrated HM-FDI and ARC algorithms; (vi) Test, tune and evaluate the performance obtained using the SI, HM-FDI, and ARC algorithms for the F/A-18 aircraft models and data; (vii) Develop a conceptual design for the SI, HM-FDI and ARC software toolbox that can be readily integrated into the IDEAS and MATLAB environments. In Phase II we will extend our approach to a larger set of failures and structural damage, to nonlinear F/A-18 models, and complete the development and delivery of the toolbox in IDEAS and MATLAB environments. Our main objective in Phase II will be to demonstrate the viability of our algorithms and software through hardware-in-the-loop piloted simulations. Boeing Phantom Works and SAIC will provide technical and commercialization support in all phases of the project.

Title:Adaptive Reconfigurable Control Based on a Reduced Order System Identification for Flutter and Aeroservoelastic Instability Suppression
Abstract:Reconfigurable multivariable flight control using an indirect adaptive algorithm is proposed for aeroservoelastic (ASE) instability and flutter suppression in the presence of aircraft system failure or battle damage. A reduced order procedure using an effective and rigorous proper orthogonal decomposition technique (POD) is adopted to reduce all critical modes collected from an offline instability study called massive failure screening. It acquires the flutter/ASE sensitivity parameters using a unique computational aeroelastic/aeroservoelastic MDO/Analysis software tool ASTROS*/ASE, developed and advanced by ZONA under AFRL support since 1996. Massive failure screening and POD are essential techniques that will promote the efficiency of the parameter estimation for real-time system identification. Selections of optimal sensor locations and the on-line search and comparison of the critical modes with sensor outputs can then follow. The minimum variance control scheme proposed is a very efficient optimal scheme for output response minimization. Continuous on-line monitoring will be applied to the control system except the minimum variance control. Switch-on gauge is based on a threshold whenever impact or diverged responses overrides the gust/white noise levels. F/A-18 will be used as the baseline aircraft to demonstrate and validate the proposed reconfigurable controller in terms of its algorithm stability, efficiency, effectiveness to flutter/ASE instability, fault-tolerance, and overall performance with cost considerations.

Title:Affordable Composite Heat Exchanger
Abstract:Advanced ceramic-based composite heat exchanger has the potential to reduce weight, improve ECS performance, increase aircraft payload, and decrease life-cycle cost. Allcomp has assembled a strong and experienced team to address all relevant issues to design and produce a functional composite heat exchanger for V22 at affordable price. It is also our belief the developed technology can be easily extended to other naval A/C platforms. It is our intent to leverage on the on-going Air Force funded F/A-18 prototype C-C Heat Exchanger activity. However, critical issues that were not addressed under the Air Force program are identified for further evaluation under this proposal. Four key issues will be investigated under Phase I effort. It includes cost (material and process), environmental resistance (oxidation and corrosion), carbon based joining and design methodology. Innovated solutions will be identified and validated for heat exchanger application. Full-size test panels and quarter-size cores will be fabricated for material characterization and manufacturing process verification. A successful completion of Phase I will provide a solid foundation to Phase II effort where a comprehensive technology base will be integrated and applied to produce and eventually to commercialize composite heat exchangers for ECS applications.

Title:High Performance Carbon-Carbon Plate Heat Exchanger
Abstract:Advanced Thermal and Environmental Concepts (ATEC), Inc. in collaboration with Carbon-Carbon Advanced Technologies (C-CAT), Inc. proposes to develop a carbon-carbon composite weight efficient, compact air-to-air heat exchanger for the V-22 application. The development effort takes advantage of a number of innovative technologies unique to ATEC and CCAT. These technologies include, the use of a carbon-carbon high modulus composite material for high temperature application, electrohydrodynamic (EHD) enhancement of the heat exchanger performance, and advanced design structures for producing compact and weight efficient parallel plate counterflow heat exchangers. There are a number of advantages using the proposed design, including: (1) extremely high effectiveness (greater than 90% with EHD and 80% without EHD), (2) high throughput and low pressure drop, (3) high resilience against high temperature degradation and decomposition, (4) simple design and manufacturing process, (5) damage tolerant, and (6) extremely light and compactness. During Phase I, we will further develop the concept presented in this proposal, perform analytical and computational modeling for feasibility study and demonstration of the significant weight and volume reduction advantage and improvements in the specific conductance of the heat exchanger. ATEC/C-CAT team will also show feasibility and prototyping of the proposed manufacturing approach for a single layer heat exchanger. Additionally, we will investigate the feasibility of deposition of a ceramic coating on the internal surfaces to yield higher temperature tolerance and corrosion resistance under hostile V-22 environment. Efforts during Phase I option will be focused on development and testing a multi-layer geometry, which will be adopted for prototype and final product development during Phase II.

Title:A Designed-to-Cost Turbojet for Target Drone Applications
Abstract:The Navy seeks low cost target drone turbojet engines based on the technology used in current hobby turbojet engines. These hobby engines rely on simple designs based on automotive turbocharger components and technology. Inherent to these hobby engine designs is a low overall engine pressure ratio and low turbine inlet temperature. These two features permit the design of an engine with a relatively simple compressor and an uncooled turbine, which may be executed using the inexpensive cast component technology used in automotive turbochargers. Advanced Projects Research, Incorporated (APRI) proposes a design using these operating conditions and simple cast components. Formed metal parts are used for the bulk of the remainder of the system. To execute the design, fabrication, and eventual production of the proposed engine, APRI has teamed with Turbonetics, a manufacturer of automotive turbocharger components and systems. This permits the proposing team to develop components specially suited to the requirements of the proposed target drone engine while still taking advantage of the existing turbocharger manufacturing technology and infrastructure.

Title:Motion Coupling in a Deployable Virtual Environment Trainer
Abstract:A preliminary design concept is presented for development of a deployable Helmet Mounted Display based Virtual Environment Training Device. The Phase I process lists key technical risks in development to mitigate the primary deficiencies of existing systems: 1) Provision of appropriate cueing system synergy (bandwidth and latency) necessary to support the high bandwidth inter- and (intra-) sensory neural correlation processes of the human primarily through design requirement specifications for display subsystems. 2) Provision of integrated system cueing compensation processes to satisfy intra sensory temporal correlation requirements. 3) Real time measurement of Virtual Environment fidelity presented to the user with recovery of neuro-physiological based fidelity metrics (e.g., during saccades; retinal slip), allowing optimization of user/training performance. The Phase I design requirements will provide high bandwidth synergism between Virtual Environment channels pre-requisite to support integration of operational environment motion conditions (e.g. ship motion) into the Virtual Environment while mitigating the severe limitations encountered in development of such systems. Inclusion of a motion cueing subsystem within the system architecture also allows extension to training in dis-similar motion environments. Furthermore, Phase I system design specifications will be directly applicable to the improvement of many existing Virtual Reality devices.

Title:Advanced Time Management for Distributed Systems
Abstract:Distributed Simulation is becoming an increasingly important aspect of DoD training, analysis, and acquisition processes. However, certain technical hurdles have yet to be overcome. This project addresses specific problems in meeting message passing bandwidth and latency requirements. New time management paradigms have yet to be exploited by existing HLA RTIs. These include approximate time protocols, repeatable real-time techniques, and synchronized data distribution management. Embedding these technologies in an RTI gives a federation new control of its execution environment. By understanding underlying network infrastructure and specific simulation requirements, we can make use of these new controls, optimizing the performance of the system, and ensuring correct system behavior.

Title:The Federation Application Integration Infrastructure (FAII)
Abstract:The Navy's aircraft simulators are a complex and diverse set of systems with unique data models, varied timing schemes, and different hardware architectures, all of which must be accommodated in order to achieve interoperability through HLA. This proposal presents an experience-based, federation engineering approach that exploits lessons learned in previous, successful programs involving similar techniques and technologies. The interoperability solution proposed lies in the use of a number of existing elements applied across the problem domain. These include: Object Model Repositories, Agile FOM mapping tools, DDM tools, middleware, gateways, and federation planning, monitoring, and analysis tools that support the Federation Development and Execution Process (FEDEP) model. We present a framework within which interoperability can be achieved when a sound approach to applying HLA to the integration of disparate simulation systems is followed. This solution is based on a federation engineering approach employing the FEDEP across the diverse set of naval flight training systems. The proposal provides a well-tried and proven approach, discussing how VTC will capitalize on our past experiences to develop a "Federation Application Integration Infrastructure (FAII)" to provide interoperability between joint military training systems and simulations.

Title:Networked Avionics Part Task Trainer
Abstract:Cost effectiveness, and training capability, associated with avionics Part Task Trainers (PTTs) can be significantly improved by incorporating Internet based technologies. The resulting increased PTT functionality enables collaborative aircrew-to-aircrew and aircrew-to-instructor training. AAC proposes to develop a client/server interface with supporting software applications to perform networked data messaging over the Internet enabling multi-user state data sharing between User "Client" Applications and a server. The Phase I conceptual design defines the Networked Avionics PTT comprising a mixture of Commercial Off-The-Shelf (COTS) C/C++ software, and innovative custom software applications to create a system of networked PTT client applications, an instructor application, and a server application over the Internet. The applications utilize Dynamic Linked Libraries (DLLs) insuring flexibility, adaptability, and product reuse with multiple avionics emulations (e.g., Multi-Function Displays, Heads Up Displays, and Control Panels) resident in multiple aircraft platforms (e.g., F-16, F-18, V-22, ATF, and Commercial Aircraft). The instructor application supports controlled asynchronous fault insertion into targeted PTT user systems for degraded avionics training. A full analysis, design, proof of concept demonstrator, and final report will be provided under Phase I. A validation demonstrator using the AH-1W Control Display Navigation Unit Emulation (CDNUE) will be provided as a Phase I option.

Title:Web Based Client/Server Interface for Part Task Training
Abstract:This exciting SBIR project will develop a real-time web browser client/server interface module and supporting client and server software for Collaborative Part Task Training (CPTT). The hardware module will interface multiple aircrew Control Display Units (CDU) and consoles used by the flight training instructors. The project will develop real time network software that will function in a standalone or in an internet server (interactive training) mode. The project will develop the CPTT software for a server and distributed embedded clients that will provide bi-directional synchronous and asynchronous data transfer over the Internet, local, or commercial lines of communication. The CPTT will enable remote supervision by instructors who will have the ability to insert realistic faults and failures that will test the student's abilities. The CPTT data transfers will enable server administrative management of single or multiple remotely sited PTTs as the same time. In phase I a prototype system will be demonstrated using the Navy funded FlightLab Software for H60 helicopter training liinked for collaboration PTT with a P3 CDU.

Title:SHALLOW WATER DIRECTIONAL NOISE MEASUREMENT SENSORS
Abstract:Environmentally adaptive sonar decision aids are needed to help sonar operators determine how to effectively deploy sonobuoy fields. Previous evaluation of the Airborne Low Frequency Sonar (ALFS) system indicated search rate improvements of 30%-100% are theoretically possible through proper selection of sonar deployment parameters. Achieving these improvements depends on an ability to predict acoustic coverage. Practical use of these predictions requires feedback via in situ measurements to improve the estimates of the actual environmental characteristics. This SBIR will estimate the potential improvement in acoustic coverage achievable through selection of effective IEER/ADAR multi-static deployment geometries. The following will be determined as part of this Phase I effort: (1) Sensitivity to knowledge of the environmental parameters, (2) characteristics of an air-deployable sensor that utilizes Matched Field Techniques to estimate environmental parameters over an ocean volume, and (3) feasibility of implementing such a sensor in an A-size sonobuoy configuration.

Title:Shallow Water Directional Active Measurements
Abstract:This SBIR proposes the design of an expendable directional noise measurement sensor for in-situ (using tactical sonobuoys or dipping sonar) or post analysis (using an Environmental Measurement Buoy (EMB)) of environmental acoustic parameters which impact the performance capabilities of sonar systems. These data would be inputs to acoustic performance models such as Tactical Design Aids (TDAs). Variants of this sensor could provide affordable environmental data acquisition for commercial and other Department of Defense applications. The technical objective is to formulate a design concept and demonstrate feasibility of an "A"-size air-deployed expendable directional noise and reverberation sensor. This sensor will obtain real time, environmental data in shallow water to optimize the deployment and performance of acoustic sensors and systems. The sensor will be used to collect data for historical data bases and predeployment forecasting of future missions. The Navmar sensor will be capable of measuring the following parameters; directional ambient noise and reverberation, bottom depth and transmission loss for both monostatic and bistatic measurements in water depths to 1000 feet. From the above parameters, bottom loss and bottom backscatter can be calculated through the use of models. Sensor characteristics to be considered are dynamic range, source level, bandwidth and in-buoy processing.

Title:Flexible, High-Speed Video Display Processor using Field Programmable Gate Array
Abstract:The bandwidth required to drive infrared (IR) emitter arrays, used in hardware-in-the-loop simulators, has been increasing exponentially. Advanced mega-pixel arrays are taxing the controllers, pixel buffers and processing electronics needed to drive these arrays. As array resolution and frame rates increase, the bandwidth required to drive these arrays will only increase. InterSpace, Inc. has developed a unique array driver architecture that will not only satisfy current bandwidth requirements of IR emitter arrays, but is also expandable in memory capacity, bandwidth and functionality. By taking advantage of recent advances in high-speed mega-cell field programmable gate arrays (FPGAs) and direct Rambus memories, InterSpace, Inc. will develop an IR emitter array driver with sufficient bandwidth and flexibility to meet the needs of current and future arrays.

Title:High-Bandwidth Scene Projector Drive Electronics
Abstract:As infrared scene projectors evolve from their current 512x512 pixel emitters to larger arrays, technologies are needed to develop drive electronics capable of processing the higher data rates that these projectors will require. A 16-bit 1024x1024 scene running at 200Hz corresponds to a data stream of 420 megabytes per second (1024 pixels x 1024 pixels x 2 bytes x 200 Hz). Drive electronics for an emitter array, regardless of size, must perform as a minimum: (1) acceptance of 16-bit data from the scene generation computer, (2) perform pixel-by-pixel non- uniformity correction with sufficient accuracy so as to preserve the fundamental resolution of the emitter array, and (3) format the data for emitter array: timing, scaling, scan conversion, etc. Additionally, the electronics typically has local memory for storage and playback of brief display sequences. This proposal is to develop a design for an electronic subsystem for processing scene data as described above. This system should be scalable so that it can be adapted to larger arrays as they are developed, adaptable so that it can be used with a variety of emitter arrays, and flexible so that it can be utilized in scene injection applications as well as scene projection.

Title:Novel Signal Processing Algorithms to Exploit and Classify Active Sonobuoy Returns
Abstract:AETC Inc. proposes to develop and demonstrate clutter rejection algorithms for airborne active ASW systems operating in high clutter environments. These algorithms will exploit nonlinear dynamics to cancel clutter and leave desired target echoes largely undisturbed, significantly increasing the probability of detection and reducing the probability of false alarms. Recent research has shown that modeling radar clutter as the output of a nonlinear system allows the receiver to successfully distinguish between clutter and target echo. Such nonlinear "clutter cancelers" have been implemented as hidden Markov models, nonlinear Kalman filters and neural networks. All methods take advantage of the fact that-in contrast to completely random noise-clutter is a low-order chaotic signal that can be predicted, if for only for a short time horizon. One experiment using this approach to extract acoustic signals from chaotic clutter reported a 27dB increase in signal-to-clutter ratio. Investigation by AETC Inc. has shown that active sonar reverberation and clutter also display these low-order nonlinear dynamics which are amenable to modeling and cancellation. AETC Inc. proposes to adapt these breakthroughs in radar processing to develop nonlinear clutter canceling algorithms for active sonobuoy use and demonstrate their effectiveness using recorded sea test data.

Title:Advanced Broadband Signal Processing Algorithms for Detection and Classification of Targets in Highly Cluttered Sonobuoy Data
Abstract:A set of advanced broadband processing algorithms and a broadband classifier are being proposed for clutter rejection and detection/classification of weak targets in sonobuoy returns. Novel algorithms for the harsh shallow water acoustic environment are needed since the threat model for the ASW has shifted from deep to shallow water. Recent efforts by the underwater community have identified the advantages of using broadband signals and new processing techniques to limit the effects of reverberation. This effort proposes an unconventional approach that exploits the broadband nature of explosive or impulse-like sources, as well as the new generation of coherent broadband acoustic sources the Navy uses. This broadband approach achieves very good array gain and dynamic range using a limited number of sensors. This technique uses degrees of freedom in the frequency domain, by drawing an analogy with degrees of freedom in space in a discrete line-array. The algorithms being proposed include broadband adaptive filtering, beam canceling and modified eigen-vector beamforming techniques. These algorithms are used to feed a broadband classifier based on a time/frequency wavelet analysis, and are expected to enhance the performance of future ASW systems operating in high clutter environments.

Title:Small GPS Controlled Reception Pattern Antenna for Aircraft
Abstract:Aircraft and missile platform needs are advancing the development of Global Positioning System (GPS) user equipment by requiring increasingly smaller, more affordable, and higher performance hardware. Spatial nulling techniques using Controlled Radiation Pattern Antennas (CRPAs) are very effective at countering jammers and spoofers in harsh environments. However, the size and cost of existing CRPAs make them unsuitable for new aircraft and missile platforms. Therefore, a need exists to reduce the size and cost of GPS CRPAs while maintaining or improving radiation pattern and Low Observable (LO) performance. There are established theoretical analysis and simulation tools which provide the basis for a new reduced size antenna design using higher dielectric constant materials. For example, using a material with a dielectric constant of 50, an existing element CRPA could be reduced in size from approximately a 14 inches in diameter to under 5 inches. These antenna elements will be prototyped and manufactured using advanced tools. DARPA is funding CMS and Raytheon in the development a CAD/CAM tool capable of depositing a wide variety of materials on diverse substrates ("any" shape). This new "mesotool", could significantly increase production rates, lower labor and material costs, and improve the yield for manufacturing GPS antennas.

Title:Small Tactical Antenna Array and Electronic Control (STAEC) Unit
Abstract:The U.S. Navy dependence on GPS continues to increase, making it imperative to protect the GPS signals from radio frequency interference (RFI). Spatial nulling by CRPA systems is very effective at countering these RFIs, however, current CRPA systems are large and expensive, therefore unsuitable for current and future airborne platforms. The present SBIR Phase I proposal addresses this Navy requirement and proposes a Small Tactical L1/L2 CRPA (equivalent to 5" diameter circular array) Antenna Array and Electronic Control (STAEC) employing spatial-temporal processing architecture that provides cost-effective anti-jam capabilities. The small antenna array and digital antenna electronics design derives its legacy from a proven Mayflower GPS adaptive antenna solution. The proposed STAEC solution employs a novel signal processing approach that is effective against wideband jammers and aircraft multipath. The Phase I research will include modeling and simulation of the antenna array, as well as prototype antenna array measurements in anechoic chambers to demonstrate the performance of the small array by generating measured data of key system elements. The Phase II program will design, fabricate and demonstrate a prototype STAEC unit consisting of the small array and the digital beamforming/nulling electronics. The cost goals for the STAEC unit will be validated in Phase II.

Title:Small GPS Controlled Reception Pattern Antenna for Aircraft
Abstract:The purpose of this proposed effort is to provide a design for a new generation of GPS CRPA which will have superior anti-jam performance against a large number of intentional interfering sources than is currently possible. At the same time, this new antenna (including electronics) will be designed for a small aperture, have reduced Radar Cross Section and minimum cost in commercial production quantities. This proposal demonstrates an in-depth understanding of the GPS system as it relates and responds to jamming and interference signals, and will highlight experience in antenna design, measurement and fabrication. MRC, allied with Compton Research, Inc., provides a unique capability to analyze, design, and in later phases, fabricate and measure new integrated GPS hardware. MRC is well known for its special purpose antenna design and fabrication, but MRC has also designed, built and tested large scale integrated electronics which in one instance is a GPS antijam filter. This effort is proposed to investigate antenna configurations given the satellite, GPS receiver and interfering signal spatial envelopes. An array of designs and cost tradeoffs will be delivered.

Title:Expendable Broadband Projectors for Undersea Warfare
Abstract:Use of active sonar systems for shallow water anti-submarine warfare and mine warfare is highly attractive owing to its potential for improved target detection and localization. Unfortunately, adverse environmental conditions in shallow water scenarios can degrade the performance of active sonar. Improved performance is possible, however, if the sonar system can adapt to its environmental conditions. New transducer technologies that offer both spectral and spatial adaptability promise superior detection capabilities. This proposal considers the novel application of arrays of flextensional type actuators, sandwiched between cover plates. This innovative combination of flextensional drive elements and mass loading by cover plates permits low-frequency operation from an extremely compact unit. This work effort will make extensive use of state-of-the-art transducer models and extensive design expertise to determine efficacy of the proposed technology and provide a rapid virtual prototyping capability. Different types of flextensional geometry, multilayered configurations and hybrid mixed-frequency devices will be considered. Experimental prototype fabrication and characterization will be used to demonstrate the validity of the hybrid finite element modeling strategy. The proposed approach holds great promise for a new level of performance and adaptability in a cost effective, compact and efficient unit.

Title:Compact, High Efficiency IRCM Laser Source
Abstract:Current Band IV DIRCM laser sources suffer disadvantages such as excessive size and weight, limited duty cycle, low output power and the need for an operational "warm up" time. These disadvantages make it difficult to utilize these sources on space-limited combat aircraft. Conseequently, compact, MWIR laser sources that can operate with high electrical efficiency at elevated temperature are needed for next-generation spoof-and-jam systems. Coherent Technologies, Inc. proposes an innovative solution to this problem that leverages recent advances in laser and nonlinear optics technology. In Phase I, Coherent Technologies, Inc. will demonstrate a room-tmperature, multi-watt cw MWIR laser transmitter that operates with high electrical efficiency. A growth path towards an extremely compact system that can operate at elevated temperatures will be provided. In Phase II a prototype waveform-agile, Band IV transmitter that can be integrated with an existing CM system will be constructed and tested. This effort will leverage multiple successful CTI demonstrations of on-time, on budget, turn-key, flight-qualified electro-optics systems. This combined Phase I/II effort will provide the Navy with a low-risk, near-term route towards a substantial improvement in DIRCM technology.

Title:A Day/Night Window System for Imaging Targets from a Supersonic Missile
Abstract:Oman Moments, Inc. will conduct a Phase 1 trade study to determine the best approach for providing both day and night imaging of ground targets from a supersonic missile. The objective is to develop a practical window system that permits both visible and IR operation in the missile's thermal environment. The key challenge is reducing the in-band IR thermal emission from the window material. This emission must not fog the image to reduce ground target image contrast below the level required for target recognition. A Baseline system will be defined for comparison of alternatives. Special phenomenology issues will be investigated, especially non-traditional band pass performance. Window materials and configurations, optical band regions, modes of protection and deployment, focal plane technology options and missile integration issues will be traded to choose a recommended approach. Phase 1 will define system parameters and specify required testing for a proposed Phase 2 program. Window system design candidates will be ranked according to the terminal Mach number at which standardized images of ground targets are discernable. To perform this study we have formed a team of experienced specialists in aerothermodynamics, optical sensing, properties of optical materials, and IR and visible phenomenonology.

Title:Survivable EO/IR Sensor Windows for Supersonic Missile Applications
Abstract:Electro-optical imagers used in high velocity applications such as supersonic aircraft and especially missile seekers require a window element to protect the imager assembly from the external environment. Traditionally these windows have been spherical concentric shell elements to minimize optical aberrations over gimbal angle. These shapes are not aerodynamically efficient, resulting in high drag and large thermal transfer between the flowfield and the dome. Previous programs have utilized covers, deployable sensors, or active cooling to minimize thermal transfer. This program proposes to examine the benefits of combining aerodynamic dome shapes and minimization of thermal transfer via covers or active cooling. The collective expertise of OPTICS 1 and SAIC in the areas of optical design and analysis and aero-thermal modeling and analysis for aerodynamic shapes and will be focused in this effort. Relative benefits of previously tried and new methods will be investigated to enhance the achievable resolution and sensitivity required for the long stand-off range requirements of tomorrow's missiles.

Title:GPS Ground Plane Nulling Antenna
Abstract:Many existing weapons and platforms presently have Fixed Reception Pattern Antennas (FRPAs) that have no AJ GPS capability. There is a desire to upgrade these systems to incorporate AJ antennas. This SBIR topic solicitation desires a FRPA that provides a minimum of 20-dB attenuation of signals that are less than 5 degrees above the horizon and 0-dB gain for angles greater than 20 degrees above the horizon. In addition, the antenna should mount conformally to the top of the weapon on a flat surface and should fit in the existing 3-inch aperture. Toyon Research Corporation proposes to develop a small FRPA that is designed to provide nulling of GPS jammers on the ground while still allowing reception of GPS satellite signals. Our approach is to use an innovative design methodology, which we have been using successfully to develop small, single element, AJ GPS controlled receive pattern antennas. Specifically, Toyon will use our techniques for designing Electronically Reconfigurable Antennas (ERA) to develop a 7-cm, anti-jam FRPA for retrofitting JSOW missile GPS antennas.

Title:An Innovative Low Cost TCXO for GPS Receivers
Abstract:This SBIR topic identifies an important requirement in further advancing and expanding the application of GPS technology in DoD and commercial applications, namely, the need for a temperature compensated or other low power oscillator that provides the same quality performance as today's Oven Controlled Crystal Oscillators without the size, weight, power, and cost penalties of the oven controlled oscillator. There is no existing crystal oscillators that will meet all the requirements of this SBIR topic. Furthermore, we believe no existing crystal oscillator technology is capable of meeting these requirements. Therefore, innovative technologies capable of producing crystal oscillators meeting these requirements must be developed. There is a huge market for crystal oscillators meeting these requirements, for a wide range of military, commercial and consumer applications. The objective in Phase I is to define and prove the feasibility of an innovative technology using new temperature sensors and actuators to compensate for temperature change and hysteresis under normal temperature change, in order to achieve high quality crystal oscillators. The new TCXO developed from this project is expected to meet all the requirements set forth in this SBIR topic, and will find widespread use in other DoD applications and in the commercial and consumer markets.

Title:Precomputed Clutter Characterization for Automatic Target Recognition
Abstract:For every Automatic Target Recognition (ATR) application, a class of clutter can be defined as target-like because most false alarms originate from that category. If this class of target-like clutter can be accurately defined for a given ATR application and precomputed, then the false alarm rate for that application can be significantly reduced and throughput rate increased. In particular, the classifier's decision surface can be crafted much more accurately through the use of negative training examples (training samples labeled "non-target"). The first step of our proposed approach is to cluster all clutter in a self-organized manner using a hierarchical Adaptive Resonance Theory neural network. Self-organization is critical since only an unbiased analysis across the full clutter space will allow us to uncover all potential target-like clutter clusters. The second step is to analyze each cluster using the statistical classification technique known as Support Vector Machines to choose members from the clutter categories to use as negative training examples for the ATR's own classifier. This approach enables automatic selection of the members ("support vectors") closest to the target category in feature space, those members most likely to cause false alarms. The approach will be evaluated on in-house developed ATR algorithms.

Title:PC-Based Real-Time Target Detection/Recognition Algorithms for Still and Video Images
Abstract:Real-time image-based pattern recognition is critical in many military and commercial applications. A common approach is 2-D correlation between the acquired image and reference prototypes. This usually requires immense amount of memory and computation throughput and is achieved using special hardware. Also, the pattern recognizers are specifically tuned to a given problem. The goal of designing "universal classifiers", so that a diverse set of image recognition problems can be handled in a unified framework, has been elusive, largely due to the fact that feature extraction has been largely problem dependent. In this Phase I effort, ImageCorp, Inc. proposes to address theoretical and practical issues involved in designing a PC-based real-time target detection/recognition system that can be used for a diverse set of image-based recognition problems. We will investigate the performance of several pattern recognition techniques for real-time target detection/recognition in terms of computation, memory requirements, detection/recognition accuracy, and generalizability. The algorithms to be analyzed include our recent algorithms for face recognition using discriminant analysis, finger print classification, Ladar/Flir ATR, and target seeking, as well as selected well known approaches in the literature. A prototype system built by novel integration of promising techniques will be developed during Phase II.

Title:Fast Pattern Recognizer for Real Time Pattern Recognition
Abstract:The US military has need for a Fast Pattern Recognizer (FPR) System for guided cruise missile applications to autonomously detect, identify, correlate, and track complex mobile military targets in hostile, high-clutter environments in real time. Similar real-time needs exist in commercial applications for image correlation, identification, and recognition for law enforcement, medical, security, product assurance, and other imaging applications. Since image correlation is computationally intensive, real-time processing must be accomplished by means other than available traditional hardware and/or software. The proposed FPR system easily accomplishes this task with rated processing speeds equivalent to 250_600 MHz Pentium III PC's. During Phase II, this speed will be increased an order of magnitude to the equivalent of 2500_600MHz Pentium III PC's by implementing the FPR as an application specific integrated circuit (ASIC) chip-set in a multi-chip module (MCM) that is less than two inches square. The latter version will offer additional benefits in reduced power, size, weight, and cost while increasing circuit density, processing power, and throughput rates for virtually all image-processing applications. The FPR module is hosted as a Pentium PC peripheral processor with all the benefits of standard PC operating system, software and hardware.

Fortunately, for RCS problems the areas needing treatment are localized, and for EMI problems the on-board sensor locations are known ahead of time. This enables significant optimization of the absorber to minimize cost and size. A new absorber is proposed that uses this fact to full advantage. It is proposed that a very thin layer of metallization, containing a pattern of small resistively loaded elements, be added to an existing thin iron-loaded rubber type of absorber. The advantages of adding this layer are threefold. First, the orientation and loading of the elements provide the anisotropy needed for absorption of arbitrarily polarized waves. Second, since the absorption takes place in a very thin layer instead of over a volume, it is inherently lightweight. Third, the pattern can be optimized and fabricated using low-cost printed circuit board techniques. The type of absorber proposed is sufficiently pliable to be easily cut and wrapped to cover the surface where needed on military and commercial vehicles.

Title:A Portable Raman Instrument for Fuel Characterization
Abstract:Rapid, "on-demand", fuel analyses are required to assess stored, host nation or captured fuel supplies to ensure readiness and optimize battlefield performance. Unfortunately, current field techniques provide only limited information, while laboratory techniques are labor intensive, slow, and costly. Recently, spectroscopic methods such as near infrared, mid infrared, and Raman have been successfully used to determine fuel quality parameters. These instruments, however, have been designed for laboratory use and simply are not rugged or portable. This proposed program will develop a rugged, hand-held, light-weight, low power Raman spectrometer, that provides fluorescence free, wavelength stable, sensitive measurements suitable to "on-demand" field analyses of fuels. Phase I will focus on instrument development and demonstrate feasibility using a unique, small optical design. It is based on technology developed by Advanced Fuel Research, Inc. (AFR) and its spin-off company, On-Line Technologies, Inc. (OLT). The design employs a 1 cm diameter optical beam that allows significant reduction in size, mass, power consumption, as well as the use of a new optical design. Phase II will focus on developing spectral libraries, calibration, and chemometric routines to allow rapid fuel analysis, as well as building a prototype instrument capable of wireless data transmission using the TC/PIP protocol.

Title:RAY-TRACING TOOL OPTIMIZED FOR PRO/ENGINEER GEOMETRY
Abstract:Vulnerability and survivability assessments require a ray-tracing tool capable of analyzing geometry created using Pro-Engineer. ThermoAnalytics proposes to extend their recently developed ray-tracer to meet this need. This modular ray-tracing tool currently calculates thermal view factors for infrared and thermal signature assessment. It incorporates the latest ray-tracing techniques including spatial subdivision. ThermoAnalytics proposes to extend this existing ray-tracer to: 1. Ray-trace Pro-E surface and solid entities, 2. Report the identity of components along the shotline, the incident angles at each intersection of the shotline with a surface, and the distance traveled, 3. Be easily integrated into vulnerability codes such as MUVES, 4. Interrogate Pro-E files to report the material properties of intersected components. This tool will eliminate the difficult translation of target geometry between commercial CAD systems and BRLCAD. This translation is presently required because the current MUVES ray-tracer functions only with BRLCAD geometry. The proposed standalone program will be capable of ray-tracing surface and solid geometry from a variety of commercial CAD systems. ThermoAnalytics will optimize it for ray-tracing files produced by Pro-E. The program will run on multiple platforms (UNIX and Windows systems). The proposed work capitalizes on the synergism between vulnerability and IR/thermal analyses codes.

Title:Real Time High Resolution Tetherless Optical Tracking System
Abstract:PhaseSpace proposes to demonstrate in applications, a 3D tracking system that will allow real time interaction of humans in computer generated environments. Tracking active markers will allow control of computer generated characters and objects in real time with less than 10 milliseconds latency. The system will be an input device capable of tracking multiple objects in a 10 x 10 x 8 foot metallic compartment. The key elements of this system will be a real time, high spatial resolution, high temporal resolution, tetherless motion tracking system comprised of smart targets, smart cameras, and sophisticated tracking software based on a commercial system already in production. The distributed processing design will enable real time control of computer generated characters and simulations. The system will be set up for one or more participants and their weapons for a total of 120 tracked markers, each with a unique binary ID to allow tracking between systems, and elimination of occlusion re-identification problems. Resolution is targeted at better than 1 mm at 2 meters.

Title:Multi-Sensory Grenade (MSG) for Non-Lethal Clearing of Facilities
Abstract:Emerging challenges to the 21st century warfighter and law enforcement officer will require the development of effective non-lethal weapons. MOUT, peace-keeping missions, facility/embassy protection, control of civil unrest, hostage rescue, counter-terrorism missions all require effective non-lethal technologies that provides profound disruptive and diversionary effects. SARA proposes the development of an innovative Multi-Sensory Grenade (MSG) that achieves profound disruption through the combined overwhelm of three human sensory systems. The MSG achieves 1) strong auditory pain and verbal communications defeat through intense sound emission, 2) production of disorienting visual flicker vertigo through intense rep. pulsed light, and finally 3) nausea and disgust through release of an overwhelming noxious scent compound. All three sensory bombardment effects occur with intensities and exposures well below any permanent eye or auditory damage threshold. The production of the intense sound, light output and malodorous components are all driven from a common long storage life high pressure or warm gas source with no electrical power required. The MSG will give the warfighter and law enforcement officer a powerful new tool in countering 21st century threat scenarios.

Title:System Level Approach to AAAV Internal Noise Reduction
Abstract:The proposed Phase I program will design active noise and vibration reduction systems for the Advanced Amphibious Assault Vehicle (AAAV) in order to satisfy specific performance-based objectives. Those objectives are: 1) maintain safe exposure limits for all AAAV personnel (crew and in-transit marines) while eliminating the need for any personal hearing protection as first-priority or eliminating the need for double personal hearing protection as second-priority; 2) ensure speech intelligibility levels greater than ninety percent; 3) improve reduction in low frequency interior noise for idling hatch-open versus hatch-closed condition; and 4) improve noise reduction in AAAV interior acoustic signatures for both 15 mph land-based operation and 25 knots marine operation. Realistic ANR designs are expected to provide significant local noise control zones (10-25 dB SPL) and more modest global noise control performance for certain configurations. The work plan offers a two-path approach 1) system-level design for global/local noise reductions and 2) personnel-level design for at-the-ear noise reductions. A subcontract with BBN Technologies will provide exchange of critical AAAV data. Existing FEM and analytical models will be requested from General Dynamics to facilitate the Phase I work. The Phase II program will validate all recommended local/global ANR designs and engine isolation techniques.

Title:Interior Noise Reduction for Armored Vehicles
Abstract:The next generation of amphibious assault vehicles will be capable of carrying 18 marines at a water speed of 25 kts and a ground speed of 45 mph, a significant improvement over current vehicles. Unfortunately, however, there is the potential for extremely high noise levels inside the vehicle cabin. This noise, possibly exceeding 120 dBA, requires individual hearing protection and makes speech communication inside the vehicle nearly impossible. CSA Engineering proposes to develop a hybrid passive-active noise suppression system for the Advanced Amphibious Assault Vehicle. This hybrid system, combining passive and active elements and inherent to the vehicle, will provide global noise reduction inside the vehicle cabin, making protective headsets unnecessary and facilitating verbal communication. Once the system requirements and constraints have been established, the suitability of a number of passive and active acoustic suppression techniques will be assessed. The best performing passive and active techniques will be combined in a preliminary design. A structural-acoustic simulation of the vehicle response including the disturbance sources will be used to evaluate performance levels of the noise suppression design. The predicted attenuation levels, weight, power, and the physical practicality of the design will be used as the metric in evaluating the design.

We explore the feasibility of the MT array connector in an towed array submarine application. Two approaches are investigated: a low risk "splice case" and a more ambitious design of an insert, possibly holding multiple 12 fiber arrays, that is compatible with a number of military circular connectors.

Title:Advanced Underwater Multi Single-mode Fiber (MSF) Optic Connector
Abstract:Further advances in underwater fiber optic conectors will require a technology leap to a new type of fiber termination. Connectors on the market today use a sherically polilshed fiber that is limited to roughly -45 dBm back reflection and cannot preserve polarity information. SEA CON proposes to integrate new fiber connection technology into the TB-29 multi single-mode fiber (MSF) 8 fiber 1 coax (MSF 8/1) connector. The most advanced fiber connection on the market today is the angle physical contact (APC) which has an 8 degree cut for mating. Back reflection can be as low as -70 dBm in APC connections. To accomplish this will require precision keying and alignment, and development of 1.25 mm ferrule/fiber retainers smaller than those used in SEA CON's recent TB-29 electro/optic connector built for L3 Inc. The SEA CON appraoch can be modified to fit any location in the array, uses current TB-29 shells, and can eventually replace the TB-23 connectors. SEA CON proposes to design and develop the alignment and fiber packing density required for the MSF 8/1 using APC technology with an HPC option (which gets to - 55 dBm) as a risk reducing backup appraoch. SEA CON's experience in producting the first 1.25 mm TB-29 towed array connector for L3 Inc. will be a key factor in accomplishing this precision driven design. SEA CON also proposes a an in-depth marketing strategy that will introduce MSF connectors to the geophysical exploration industry - the world's largest buyer of towed array electro/optic connectors.

Title:Water Based Hydraulic System
Abstract:Inadvertent releases of petroleum based hydraulic fluids into the sea can create serious adverse environmental impacts. OPNAVIST 5090.1B, the Clean Water Act, Section 311, 40 CFR 110, and other international, federal and state regulations forbid the discharge of petroleum products that results in a sheen on the surface of the water or violates water quality standards. The Submarine External Hydraulic System (SEHS) is especially susceptible to problems. This system is exposed to the submarine's full range of temperature and pressure extremes, and a leak in this system releases hydraulic fluid directly into the ocean. Texas Research Institute Austin, Inc. will team with the Milwaukee School of Engineering Fluid Power Institute and Sargent Control & Aerospace in a unified approach that involves integrating the new water based hydraulic fluids with SEHS materials and components. During Phase I, we will formulate new water based hydraulic fluids with superior performance. These new fluids will be evaluated in a hydraulic testbed. Component and material redesign/replacement in current SEHS's will be proposed (if required) to achieve compatiblity with the new hydraulic fluids. This approach will reduce Navy total ownership costs associated with the cleanup, storage and disposal of hazardous petroleum based hydraulic fluids.

Title:Search and Rescue (SAR) Using Active Light Detection and Ranging (LIDAR) Technology
Abstract:Although only two percent of maritime Search and Rescue (SAR) operations conducted by the U.S. Coast Guard every year last longer than 24 hours, they cost over $50 Million annually and, at times, result in fatalities. These incidents are extremely time-critical, and any approach that can reduce search time and increase the probability of mission success would add significant value.

A need exists to improve SAR sensor coverage for persons in the water and small life rafts, particularly for nighttime but also for daytime operations. Lidar systems are ideally suited for this mission, and we propose to apply classic SAR planning techniques to develop optimum modes of operation for the incorporation of the Airborne Laser Mine Detection System (ALMDS) as an augmenting sensor for SAR operations, and to quantify the value-added to SAR mission success.

Phase I technical objectives are: (1) Develop quantitative and qualitative measures of SAR mission improvements afforded by ALMDS , and (2) Develop a systems and operational concept for a real-time SAR Tactical Decision Aid for ALMDS. These objectives will produce the performance measures and a baseline system concept for development and demonstration in Phase II.

Title:Search and Rescue (SAR) Using Active Light Detections and Ranging (lidar) Technology
Abstract:Lidar systems intended for detection of surface and near-surface mines may be candidates for use as sensor systems in Search and Rescue (SAR) operations at sea. Lidar systems have the capability of searching at significant area search rates during the day or night in a variety of ocean conditions using automatic target recognition (ATR) software. This Phase I SBIR will investigate the feasibility of using lidar systems designed for mine detection in the SAR role. Test data from existing systems will be reviewed to provide a baseline of performance against near surface objects. Additional modeling of existing systems will be undertaken to determine the likely detection performance of the existing systems with respect to survivors in the water and in a variety of rafts, with and without the presence of sea dye marker, in both a day and night search operation. Changes to parameters and software of the existing lidar systems will be specified that will optimize the detection performance of existing systems. We will also develop a plan for adapting existing tactical decision aids to support the lidar SAR mission.

Title:Scriptable Human Animation Figures in an Open Enviornmental Framework
Abstract:One of the most critical engineering issues is how to integrate parameters of human factors into the design process. The traditional design process tends to put a disproportionate focus on the technical performance of equipment, with little regard for the human component. This project will link human performance modeling and simulation software with human anthropometric models in an open framework that will allow multiple simulations to access situational awareness of a 3D world. The simulations will then be capable of driving human figures in this three-dimensional virtual world and obtain feedback from the physical model. This effort will allow for dynamic interaction between software tools (during the execution of a simulation) as well as data flow for static, or scripted information. Micro Analysis & Design is the proven leader in human performance modeling with ongoing development for the US Navy, Army, Air Force and Joint Commands. For this effort, MA&D has teamed with Deneb Robotics, a worldwide leader of CAD independent digital software, including Deneb/ERGO, an accurate, physics-based human motion and task analysis tool. Joining the team is BCI, Inc., which combines the experience of engineers and command warfighters to provide a unique capability to determine future system performance parameters.

Title:Innovative New Material Form for Cost Effective Expeditionary Shelters
Abstract:Triton Systems Inc. proposes to develop a new unique rigid wall expeditionary shelter based on an innovative continuous manufacturing process initiative that was invented by Triton for the automotive industry for rapid production of structural flooring. Triton's high performance laminated composite panels are made from inexpensive post consumer recycled material in a low cost, high volume continuous manufacturing process. The proposed tactical shelter system would meet the Navy's need for environmentally friendly and durable materials that reduce deployment and life cycle costs through reduced weight, increased service life and a commercially valuable recycled material or energy product at the end of service life. These thermoplastic composite shelters will outperform, and will have lower total life cycle cost than wood, fiberboard or steel based products due to there inherent mechanical properties and superior resistance to environmental deterioration. The proposed innovative continuous processing will allow for the production of curved or shaped panels, and by consolidation and forming the edges insitu, will afford integrated panel attachment and assembly systems without reworking or significant hand labor, thus reducing total shelter cost. The incorporation of integrated attachment and assembly hardware will allow for deployment without the use of fasteners and will provide for easy disposal and recycling at the end of service life. In Phase I we will demonstrate the thermoplastic processing and superior mechanical and environmental performance. The Phase I option will be devoted to developing interlocking panel edge systems leading to preproduction development and qualification of full size shelters in phase II.

Title:Compact Wetland System for Washrack Effluent
Abstract:Gradient Technology proposes to develop a compact and modular wetland system for the treatment of washrack effluent. The system was designed through the combination of best engineering practices and the latest in wetlands research, yielding a system that requires a fraction of the area as a typical constructed wetland. The "Compact Wetland System" (CWS) presently consists of two modules. The first module handles solids and a majority of the phosphorus and nitrates. The second module finishes the stream to discharge standards. Creative hydrodynamics and optimized macrophyte clustering result in a highly efficient system. Phase I will demonstrate the proof of concept with a combination of pilot-scale laboratory experiments and simulations. Phase II will see the construction of a working demonstration facility.

Title:Constructed Wetland System for Treatment of Washrack Effluent
Abstract:Under the Clean Water Act, the EPA is developing effluent guidelines for facilities that generate wastewater while processing metal parts, metal products, and machineries. The proposed rule covers maintenance activities such as aircraft engine washing and establishes daily and monthly discharge limits for analytes. Currently, the Navy's T-56 engines contain parts that are electroplated with nickel-cadmium. Testing of the effluent from these engines indicates that the discharge exceeds the TCLP limit of 1.0 mg/L for cadmium. The proposed Phase I research intends to investigate the technical and economic feasibility of using constructed wetlands to treat washrack effluent contaminants from aircraft washing facilities. Phase I research will develop an initial design that is compact and low maintenance. Capital costs for construction of the constructed wetlands treatment system will be comparable with existing systems currently in use and will not generate appreciable secondary waste.

Title:Carbon Composite Reinforcement For Waterfront Construction
Abstract:This proposal encompasses a reinforcement alternative to steel rebars that are deteriorating due to corrosion on waterfront constructions. Fiber reinforced polymer reinforcing has been used in the past decade as it offers great potential for use in concrete construction under conditions in which conventional steel reinforced concrete has yielded unacceptable service. A new carbon composite reinforcement concept for use in conventional reinforced and prestressed concrete structures is developed in this proposal. This design concept mitigates the problems associated with the FRP reinforcements presently used. The non-corroding characteristics of the CFRP reinforcement can significantly enhance the structural performance of concrete waterfront structures and increase the service life of the constructions. The reinforcement design proposed involves innovative materials and fabrication technologies. The proposed reinforcement concept will increase bond strength with concrete and provide high tensile strength and stiffness to the concrete structure. The new concept will reduce maintenance costs and construction time. The feasibility and cost effectiveness of the proposed design has also been addressed.

Title:Optimization-Based Antenna Design
Abstract:ALPHATECH and Atlantic Aerospace propose to study the use of numerical optimization in the antenna design process. Such a study requires not only trying optimization algorithms on design problems, but also a detailed understanding of the underlying issues involved in choosing an algorithm. When deciding if a particular algorithm is effective for antenna design, it is important that it not be judged as a "black box". That is, it should not be evaluated based only upon the final solution and rate of convergence, but it is also important to judge the suitability of the algorithm for its utility in the overall design process. It is the objective of this effort to identify optimization algorithms that are suitable for antenna design in a more general, interactive optimization-based design environment that allows the designer to explore tradeoffs between design requirements. The phase I effort will produce a survey of optimization algorithms with respect to the antenna design problem as well as a prototype of a generic optimization interface to the numerical electromagnetic code (NEC). The performance of several optimization algorithm implementations will be characterized using realistic antenna design problems.

Abstract:The Department of Defense has shown a need for the reduction of manpower and maintenance costs associated with the present door/hatch closure systems. This proposal discusses a solution to the problem with Williams-Pyro, Inc.'s innovative concept of a SMART Damage Control Boundary Opening System. The system combines advanced composites, wireless sensors, Shape memory alloys, and an innovative sealing and hinging system. Sensors embedded within the system remotely transmit relay data concerning the environment within a compartment (i.e. flood, fire, and chemical emergency), to the damage control center of the ship. Personnel would be able to evaluate the situation and either remotely or manually seal-off damaged compartments to preserve operational integrity. Composite material candidates for the door panel, doorframe and so forth are also discussed with regard to structural design and manufacturing processes. The advantages of this smart boundary opening system include minimal maintenance and an increase in the longevity of the entire system.

Abstract:Goleta Engineering (GE) proposes to start with and build upon prior and on-going efforts such as the ONR ACTIVE and the DARPA MSTAR programs to develop a robust ISAR ATR capability for USN platforms such as the APY-6, APS-137, APG-73, and JSF. The proposed Phase I effort will focus on two areas: (1) improved image formation processing using advanced signal based mocomp, time-frequency algorithms and possibly super res, and (2) robust feature extraction for subsequent ATR based upon retention of the phase in the processed image. During Phase I we will pursue teaming arrangements with one or more partners to be selected from MIT/LL, Norden, ERIM and Raytheon McKinney. GE has just successfully completed a program to develop a robust 2-D Signal Based Mocomp approach utilizing APS-137 B(V)5 radar data provided by Raytheon McKinney TX. Further, GE is currently working with ERIM to develop a robust motion-tolerant efficient image formation algorithm. These two efforts will directly assist in the first part of the proposed effort. The teaming partner(s) will be selected, contracted with and utilized during Phase I. GE will then work with the selected partner(s) to develop the features, feature extraction and ATR algorithms.

Title:Non-cooperative Moving Target Recognition Using ISAR
Abstract:Identification by radar of moving targets, including aircraft, ground vehicles, and ships, is difficult because their complex backscattering behavior is coupled with motion that is not smooth. The identification cannot be based on target shape and size alone. MARK Resources has developed an advanced radar signal processing technology for extracting detailed information about the target. It utilizes the return signal phase, which is usually discarded, and as a result it is capable of solving the identification problem. On this basis the Navy will have a reliable all-weather identification system that does not require the cooperation of the target.

Title:Maritime Intelligent Decision Aiding System (MIDAS) for Enhancing Organic Mine Countermeasures (MCM) Operations
Abstract:The use of mine warfare (MIW) by potential adversaries poses a severe threat to Naval operations in the littoral environment. However, the explosive growth in the area of information technology and the development and introduction of more capable intelligence, surveillance, and reconnaissance (ISR) platforms provide a tremendous opportunity for addressing this threat and enhancing Naval warfighting capabilities. The management, processing, and fusion of mine warfare ISR information, in tandem with the requisite assessment of enemy mine laying capabilities, intent, and objectives, form a critical element of Navy littoral environment operations. Additionally, the rapid and verifiable generation of appropriate response recommendations is also of paramount importance. Here, we propose a Maritime Intelligent Decision Aiding System (MIDAS) for enhancing tactical organic mine countermeasures (MCM) operations. Our novel system integrates a Bayesian belief network approach to support situation assessment and diagnostic and inferential reasoning, a fuzzy logic expert system-based approach for event detection and threat assessment analysis, and an argumentation-based mechanism for construction and evaluation of appropriate response recommendations. We see considerable potential for this approach in enhancing existing Navy tactical MCM systems and addressing future information dominated battlespace requirements.

Title:Maritime Intelligence, Surveillance, Reconnaissance (ISR) and Space Exploitation
Abstract:Maritime Intelligence, Surveillance, and Reconnaissance (ISR) has been critical to national defense. During the cold war, assets were developed to support the ISR mission. E-2C and S-3B aircraft performed ISR in support of Navy task groups. To monitor activities outside these task groups, P-3C and EP-3 aircraft patrolled sea lanes of high interest. Even though these assets meet the ISR primary mission, the ISR task has dramatically increased but budget limitations has prevented ISR from increasing beyond using these same approaches and same aircraft. Only a lower cost approach would allow the new increased ISR mission to be met while not increasing its allotted budget. With the development of low cost Unmanned Air Vehicles (UAVs) and small low cost payloads, a means is available to address these new requirements without significant cost increases. Even though development of UAVs has progressed, the development of small low cost, lower power ISR payloads still need to be developed. In this proposal a Maritime ISR system is described that uses the GPS satellite signals in a bistatic system architecture for surveillance. This architecture is completely passive and leverages advances in GPS electronics to provide a low cost, low power ISR solution for Maritime applications.

Title:Adaptive Threshold Control in an Autonomous Sensor Field
Abstract:An autonomous field of sensor nodes needs to acquire and track targets of interest traversing the field. Small detection ranges limit the detectability of the field. As detections occur in the field, detections are transmitted acoustically to a master node. Both detection processing and acoustic communication drain a node's battery. In order to maximize field life, an approach must be developed to control detector thresholds and acoustic communication routing, as well as the initial placement of the field. To address these problems, ORINCON proposes the development of an adaptive threshold control scheme. This technique will minimize the power consumption while still maintaining the field-level probability of detection. Acoustic communication routing of the field will also be accomplished to minimize power consumption and therefore extend the life of the field. The control law to be developed is based on two approaches, evolutionary programming and integer programming. At the end of the Phase I effort, ORINCON will demonstrate these techniques in the Deployable Autonomous Distributed System (DADS) prototype master node for testing and evaluation in the system.

Title:Pressure-Tolerant Batteries for Autonomous Undersea Applications
Abstract:It has long been known that batteries can be pressure compensated, i.e., modified to operate at depth [e.g., Work, 1968]. Unfortunately, these modifications bring along severe restrictions on vehicle handling as well as increased maintenance requirements, neither of which is acceptable for the new generation of small, low-cost, AUVs. Recent advances in polymer-electrolyte and all-solid-electrolyte lithium ion cells open the possibility of pressure-tolerant batteries, i.e., batteries that are intrinsically capable of withstanding the pressure with negligible modification. In this proposal we will demonstrate how such pressure-tolerant batteries can increase an AUV's energy capacity by 50% or more, with no reduction in vehicle payload and no increase in vehicle size. To get a corresponding increase in capacity through better electrochemistry or cell manufacturing would require many millions of dollars and many years of R&D effort, with no guarantee of success. For this Phase I effort we propose to perform the key tests required to demonstrate the feasibility of such pressure-tolerant batteries.

Title:Low Cost, High energy Density, and Pressure Tolerant Lithium-ion Battery
Abstract:A low cost, high energy density, pressure tolerant lithium-ion battery system is proposed based on doped Mn-based cathode material and low cost domestic graphite in 1M LiPF6 electrolyte with ternary carbonate-based organic solvents. A specialized cell design to limit and manage the electrolyte in soft package to provide the pressure tolerance and high energy density will be developed. A series of modified Mn-based lithium intercalation compounds will be investigated. The potential candidate materials will further be evaluated as cathodes for lithium-ion batteries. Cathodes and anodes will be prepared and performance evaluated under pressure up to 6000 psi in half-cells design. Several prismatic design lithium-ion pouch cells will be made and tested under various pressures to establish the feasibility of the proposed concept.

Title:A Precision, Solid-State, Magnetic Compass for Autonomous Underwater Vehicles (AUVs)
Abstract:MTI, Ltd. will develop a precision, solid-state, magnetic compass with an absolute accuracy of better than 0.5 degree using the innovative Scanning Magnetic Angle Comparator (SMAC) technology. A SMAC compass will offer distinct advantages over conventional compasses, because it provides more degrees of freedom to optimize performance by employing feedback via a microprocessor to minimize error. The basic SMAC compass will be a non-inertial, self-calibrating design employing commercial-off-the-shelf (COTS) magnetic sensors. It will also incorporate tilt sensors. A design for a prototype, guided by error model analyses, will be developed in Phase I. The prototype proposed for fabrication and development in the Phase I option will be about 1.0" in diameter and 2.5" long, and will be tested and evaluated in a Helmholtz coil facility. In Phase II, the SMAC compass design will be optimized and, to the extent possible, implemented using integrated circuit technology to achieve both the performance goals and the cost goal of under $1,000 per unit. At the end of Phase II, a compact, integrated SMAC compass will be available for evaluation by the Navy's autonomous underwater vehicle (AUV), towed array or extended range guided munitions programs.

Title:Using Adaptive Simulated Annealing to Estimate Ocean Bottom Acoustic Properties from Acoustic Data
Abstract:The effective use of active sonar systems in littoral environments relies on the accurate knowledge of the acoustic environment. Current Navy standard databases for ocean bottom properties provide a valuable tool for planning but do not currently provide the spatial resolution needed. Inversion of ownship and/or bistatic/multistatic transmissions for ocean bottom properties can provide much more accurate information about the acoustic environment. This information can then be used in optimizing the use of the active sonar system, in essence, tuning the sonar for the environment. Recent advances in inversion techniques, specifically Adaptive Simulated Annealing (ASA), have made these techniques tactically viable tools by significantly increasing their speed. PSI proposes to implement the ASA algorithm with current transmission loss and bottom reverberation models to develop a set of tactical tools. Each of these inversions will characterize the ocean bottom in terms of Navy standard parameters. The use of Navy standard parameters allows the immediate use of these values in performance prediction models and their use in a network-centric environment among different combatants.

Title:Model-based Beam-time Arrival Matching
Abstract:Recent advances in acoustic modeling and inversion has led to the development of new acoustic tomography approaches for rapid environmental assessment. However, most tomography work has focused on deep-water environments where the bottom interaction is insignificant. In shallow water, the bottom is the most significant environmental factor affecting sonar performance. The variability of the seabed properties far exceeds those experienced in water column, making the shallow water environmental assessment much more complex. Here, we propose to develop a new model-based approach based on identification of distinct time-angle properties of seabed reverberation which are hypothesized to uniquely characterize the seabed sound speed structure and the reverberation mechanism such as volume and surface scattering. Image processing techniques such as edge detection and template matching are used to detect the seabed characterizing features of the time-angle signal power. The algorithm is expected to be robust because the model matching is done in the signal power as opposed to phase sensitive algorithms such as Matched Field Processing.

Title:SimEdge(TM): A Web-enabled, Integrated Design Environment for Simulation-based Acquisition
Abstract:The Simulation Based Acquisition (SBA) initiative jumped to the forefront as the DoD, faced with decreasing budgets, turned to strategies to maximize effective use of the resources at its disposal. The SBA is a technology-based response to the defense mandate for Integrated Product and Process Development. The major components of SBA are the Smart Product Model (SPM) and the Simulation, Test, and Evaluation Process (STEP). The goal of this SBIR is to: (a) design an architecture to support SBA of future surface combatants and aircraft carriers, consistent with DoD requirements; (b) demonstrate the lifecycle applicability of a virtual prototype (i.e., SPM) to support SBA to actual ship acquisition. The specific objectives of Phase I are to define a virtual product model of at least one major ship system and infrastructure addressing interoperability and standards. The product of Phase I will be a concept prototype of a web-based collaborative acquisition/engineering environment that integrates members of geographically dispersed IPTs, disparate tools, and heterogeneous data bases that cut across multiple cooperating organizations.

Title:Web-based Smart Modeling Environment
Abstract:The complexity of modern ship systems has made it difficult to develop cost-effective system designs. Increasingly, system design activities involve cross-disciplinary teams of experts, each using a distinct set of tools. Data exchange between different tools is often difficult, error prone, and adds little value; consequently, collaborations that could increase system performance or reduce cost do not occur as frequently as necessary to produce an optimal system design. This proposal offers a framework for building a collaborative, smart product model over the World Wide Web. This environment will enable increased collaboration among cross-disciplinary teams for large, complex systems and the production of designs with higher performance and lower cost across the life cycle.

Title:Positron trap beam source
Abstract:This Small Business Innovation Research Phase I project will establish the feasibility of developing a Positron Trap Beam Source (PTBS) that will provide a state-of-the-art positron beam for a variety of applications in science and technology. The PTBS will produce a brightness-enhanced positron beam by employing recent advances in the field of nonneutral plasma science to achieve high-efficiency brightness enhancement. The technical objectives of Phase I are: (1) to assemble an experiment to study compression of positron plasmas by a rotating electric field; (2) test plasma compression at a low magnetic field in the presence of a buffer gas; (3) develop the conceptual design for the laboratory prototype to be constructed in Phase II; and (4) (option) investigate advanced methods for beam extraction. If successful, the experiments will provide a basis for the design and construction of a laboratory prototype of the system in Phase II. Positron beams are the basis of a variety of analytical tools for the study of surfaces and solids. The are also used in atomic physics research and have potential for application in mass spectrometry. The PTBS will advance these applications by providing beams that are significantly colder and brighter than any currently available.

Title:Integrated Tactile Transduction Garmet for In-Flight Spatial Orientation
Abstract:Foster-Miller proposes to develop an integrated tactile transduction garment for in-flight spatial orientation. Pilot disorientation is a disturbingly frequent phenomenon for military, commercial and civilian pilots. Pilot disorientation costs the U.S. military about 30 lives and over $300 million in lost aircraft annually. Speculation surrounding the recent crash of John F. Kennedy Jr.'s Piper Saratoga aircraft has, again, attributed the tragedy to pilot disorientation. Pilot disorientation generally occurs when pilots incorrectly perceive attitude, altitude, and/or motion when visual information is compromised, either through temporary distractions, increased workload, or reduced visibility. Current research at the Naval Aerospace Medical Research Laboratory is focused on developing a Tactile Situational Awareness System (TSAS) which, when linked to the aircraft's instruments, will provide attitude and spatial orientation awareness to the pilot. TSAS will use a number of tactile transducers (tactors) that are placed in arrays surrounding the torso. To assist this development, Foster-Miller will develop a garment into which the tactor arrays will be incorporated. The garment will take the form of a full torso suit which will extend from the mid-thigh to the neck, including the upper arms. The tactor suit will be designed to conform to the human torso in a uniform manner.

Abstract:Steadfast proposes to develop tactor garment technology for TSAS applications. The overall goal is to design tactor garments which extend current coverage while maintaining reliable contact with all sites on the user's skin. We will carry out this task by investigating several means of positioning tactors, including stretch materials and inflatable pannels. Prototype garments will be assembled and tested. Deliverables will include specifications, patterns, production techniques, drawings, and material and component sources. We will also provide a prototype TSAS garment for further testing and demonstration.

Title:AAAV Mineblast Attenuating Seat
Abstract:This proposal describes a 6-month SBIR Phase I proposal to develop a preliminary design for a seating system that attenuates the vehicle acceleration effects of mineblasts. A vehicle and occupant motion analysis is presented to identify the characteristics of a mineblast acceleration pulse. Human tolerance to whole-body and body segment accelerations are compared to mineblast accelerations to assess their injury potential and to define the operational envelope of a mineblast energy attenuation system. Candidate energy absorber designs are described using static and dynamic analysis methods and advanced seat design tools. A static and dynamic test plan that verifies the function of the AAAV mineblast seat energy attenuation system is outlined. Preliminary designs for the seat structure, energy attenuator, occupant restraint system, and cushion system are presented along with a system weight budget and supporting static and dynamic analyses.

Title:Advanced Concepts for Hull Array Beamforming
Abstract:The objective of this research is advanced hull array beamformer technology to reduce the levels and extent of reverberation noise effects at the input to active signal processors. AHA will investigate spatial and temporal characteristics of reverberation by processing hull array at-sea data recordings. This analysis will identify reverberation properties to be exploited by adaptive algorithms for improving beamformer noise gain. Both single-ping and multi-ping (inter-ping) adaptive algorithms will be investigated to determine the most robust approach. Candidate adaptive algorithms include element-based, beam-based, and adaptive interference canceller techniques. The research must identify innovative methods to reduce the dimensionality of the adaptive process for a hull array containing several hundred acoustic channels. AHA will model the most promising algorithm(s) to determine key performance metrics using simulated acoustic field models. A mathematically correct model will be coded to address basic performance issues, including signal gain, noise gain, and adaptive convergence rate. Second, the model will be enhanced to consider both performance and computational speed improvements. A sizing analysis will determine the COTS resources required for real-time processing implementation. This analysis will consider measured execution time of signal processing functions, memory requirements, and data transfer rates of specific COTS computer architectures.
