Title:Advanced Packaging Technology for Trident Missile Systems
Abstract:This SBIR proposal is for the development of innovative packaging of radiation hardened electronics in support of Strategic Missile Guidance System upgrades for sea launched ballistic missiles (SLBMs). The Navy Strategic Systems Programs has authorized Life extensions for the Trident Fleet Ballistic Missile Submarines Hull and Missile systems and hence there is significant interest in utilizing all advancements in technology that are available. The Navy has authorized a 20 year extension to the life of the Trident System providing a total life of 42 years; all of the vehicles will be armed with the Trident II D5 missiles. During the life of the Trident missile system the electronics are active and utilized. It is desirable to continue to upgrade the electronics with the latest technology especially technologies that improve radiation hardness. The inertial guidance electronics will be the focus for this project. The opportunity for this SBIR project will be to develop packaging technologies that can be integrated and transferred to the Trident II submarine system throughout the current and extended life of the system. AMT and it's partner Raytheon will develop and apply new technologies that include ball grid array and column grid array interconnection and plastic encapsulated microcircuits.Military systems are rapidly faced with obsolescence and parts availability issues, especially for microelectronic devices. This project will provide an opportunity to utilize commercial technologies that are widely available from large suppliers of semiconductors and significantly enhance the options for the Navy. AMT is presently developing procedures and systems for certifying commercial products for military use and this project will have direct relevance to on-going activities that will lead to high reliability electronics for military applications.

Title:Ceramic Composite Lined Metal Composite Gun Barrels for Small Arms
Abstract:Rapid fire small arms gun performance is limited by wear and erosion in the chromium plated steel gun barrels which are also heavy for infantry use. Ceramic lined steel gun barrels have demonstrated potential to eliminate the wear and erosion but have failure from cracking for lack of toughness, uniform triaxial restraint and offer negligible weight savings. Recent developments in ceramic matrix composites (CMCs) have the potential to overcome the toughness and cracking limitations of monolithic ceramics. CMC liners coupled with outer shells of metal matrix composites (MMCs) have the potential to eliminate wear and erosion, and achieve up to 50% weight savings over chromium plated steel barrels. This program will demonstrate the fabrication of very high thermal conductivity and toughness CMCs that are functionally graded into MMCs to produce a small arms rapid fire barrel which eliminates wear and erosion, and provides 50% weight savings. Modeling and simulation will be conducted concurrent with CMC composition and fabrication processing demonstration, and screen tested using vented bomb, barrel burst test and thermal conductivity. Selected processing will be utilized to fabricate select CMC composition(s) into barrels including attachments, which will be live fire tested.Ceramic composite lined metal composite tubes not only have a substantial market for all gun barrel applications in DoD, law enforcement and recreational, but such composites have a plethora of applications in engines, brakes and chemical processing industries.

Title:Ceramic Barrels for Small Arms
Abstract:Surface Treatment Technologies, Inc. (ST2) proposes the development of Electro-Spark Alloying (ESA) technology for the formation of ceramic coatings on current gun barrel steel and lightweight alternative barrel materials, such as titanium. ESA technology involves the arc deposition of metal and ceramic coatings directly onto metal surfaces. The process forms a coating with a full metallurgical bond, forms no heat affected zone in the base alloy, creates a coating that is amorphous to nano-grained in structure, and exhibits wear and erosion properties far superior to conventional coatings of ceramics and composites of similar chemistries. In addition, the process permits the investigation of functionally gradient coatings for the end-use application. In the Phase I effort, ST2 will investigate both ceramic and refractory metal candidate coatings for conventional gun steel and titanium barrel materials. Unique to this approach will be the coating of a barrel blank, followed by a rotary forging process that will maintain the structural integrity of the coating. This evaluation will include full mechanical and metallurgical analyses, as well as live-fire testing of rifled barrel components. Phase II will expand the potential coatings candidate options, and then focus on manufacturing scale-up requirements in anticipation of a Phase III transition. Lightweight gun barrels with extended life, yet using no toxic and hazardous plating materials for military, law enforcement, and commercial applications. Additional benefits will focus on the power tool industry, medical tools and implants, and engine/transmission markets.

Title:Advanced Ceramic Barrel Materials & Processing Methods
Abstract:Barrel erosion, which is produced by the combination of high temperature and pressure with aggressive propellant combustion products, and the action of the projectile, results in decreased muzzle velocities, increased projectile yaw, and decreased accuracy. New material designs are needed to mitigate erosion in gun barrels, which limits service life Ceramic composites are a leading material candidate for gun barrels because of their thermochemical stability, erosion resistance and low density. Ceramic composites can prolong service life and provide other enhancements to gun barrels. New designs and manufacturing methods are needed to integrate ceramic composite barrels with current infantry weapons, such as the M249 Squad Automatic Weapon. Thor Technologies, Inc. will team with Los Alamos National Laboratory, Materials Research & Design, and FN Manufacturing, Inc. (FNMI) to develop a novel hybrid ceramic composite design and an innovative, low-cost manufacturing method. Polymer infiltration/microwave pyrolysis processing enables manufacture of ceramic composites with integral metallic attachments. In Phase I, a prototype hybrid ceramic barrel will be produced and used to demonstrate improved service life through firing tests at FNMI. The Principal Investigator and the project team have the experience and expertise to develop ceramic composite gun barrels suitable for the infantry combat environment Enhancement of barrel service life will reduce weapon lifecycle costs. The availability of low cost ceramic composites will benefit aerospace and industrial applications ranging from jet engines and rocket motors to corrosion-proof piping for chemical processing.

Title:Nonlinear Optical Up-Converter for Eye-Safe Imaging
Abstract:Active imaging in the short- and mid-wave infrared has well-known benefits versus shorter wavelengths: eye safety, better visibility through battlefield obscurants, high atmospheric trans-mission, and reduced background emission. However, there are no suitable imaging detectors at eye-safe wavelengths. CTI proposes a nonlinear sum-frequency generator (SFG) to convert an image at 1.55 mm to a shorter wavelength where image intensifiers can be used. In addition, the SFG can provide spectral filtering and optical range-gating capability. Modern nonlinear optical materials can operate with high efficiency using modest pump sources in a compact design. CTI proposes a SFG converter with a large field-of-view, that is relatively temperature insensitive, and operates at room temperature. In Phase I, CTI will conduct detailed analyses and laboratory demonstrations to validate the proposed nonlinear up-converter. In Phase II, an imaging breadboard converter will be tested, optimized, and delivered.(1) increase detection sensitivity in eye-safe laser radar imaging, (2) demonstrate enhanced 2D LADAR imaging through SFG converter, (3) demonstrate receiver techniques through optical range-gating.

Title:Eye-safe LADAR Laser Transmitter
Abstract:This Small Business Innovation Research Phase I Project will produce a design for a monoblock configuration pulsed Er-Yb:glass micro-laser at 1540 nm, suitable for use in coastal LADAR applications at ranges greater than 1 km. Beside LADAR such a laser would be an extremely useful tool for a number of important applications; range finding, remote sensing, optical communications, etc. Our preliminary analysis indicates that the best way to meet the requirements for this laser is through an approach based on the optimal selection of pumping wavelength and cavity configuration, where both pumping and oscillation resonators form attached cavities. This method allows for scalability and versatility, while still achieving excellent performance in a relatively simple and rugged monoblock configuration.The developed system will radically improve the characteristics of lasers at 1540 nm, bringing its construction to a monoblock micro-design. In the commercial sector, the proposed laser will serve as an ideal source for parametric oscillators, high data transfer rate communication systems, spectroscopy, clocks, etc.

Title:High Performance Composite Backing Armor System for the Advance Amphibious Assault Vehicle (AAAV)
Abstract:The AAAV requires lightweight components that can be affordably produced and assembled. The goal of this SBIR is to develop an effective armor system that can use low cost materials while minimizing overall weight. Reduction in fabrication and material cost of the armor solution translates into a meaningful reduction in the vehicle cost. In this SBIR, we expand the state of the art through the use of conventional materials in innovative ways. The technology focuses of on ways to reduce the overall installed armor costs through material, and manufacturing innovations.We expect that the technology developed in this SBIR will be immediately applicable to other application areas such as Navy patrol boats, Army spall liners, and aircraft armor, where weight and cost are important. Additionaly, we belieive that we can modify the material system to allow its use as a flexible body armor material for law enforcement. The law enforcement market is very price sensitive, and many of the materials in use today are very cost prohibitive. This material would provide a very attractive alternative.

Title:Multi-Layer Interlocked Pultruded Composite Armor for AAAV
Abstract:KaZaK Composites Incorporated proposes in this Phase I project to develop a novel composite process allowing low cost fabrication of high performance backing armor for AAAV. Key elements of this process implementation include pultrusion of multi-layered glass and hybrid glass/aramid preforms in which the layers are both differentially infiltrated with resin and interlocked with a through-thickness reinforcement. The type and degree of layer interlocking will be chosen to optimize ballistic performance. The varying density of matrix through the thickness of the composite, and the possibilities of multi-resin layering will also be evaluated to optimize the performance-weight-cost tradeoff. During the Phase I project, 12" panels of different constructions will be fabricated and subjected to ballistic testing to resolve key architecture details. Upon selection of a promising composite architecture, a trial run of continuous pultrusion for that composite will be performed. This trial of a multi-layer/material composite armor will not only shed light on processing, but will also provide specimens for ballistic testing. While we intend to evaluate novel composite architectures, our primary focus in Phase I will be to develop the continuous processing parameters allowing a "good" ballistic composite architecture to be fabricated at the lowest possible cost via pultrusion.KCI anticipates that the results of the proposed project will have widespread application in governmental and commercial arenas, both as a means of fabricating highly effective backing armor for various vehicles, and as a primary armor for those applications having less demanding threats. We believe that concentrating on reducing the cost of "good" architectures is at present more important than wringing out the optimum specific weight performance in order to enhance commercialization to law enforcement and VIP protection markets. Given a low cost processing scheme for the basic multi-layered/multi-material construction, architecture modifications to optimize ballistic performance can be easily implemented, either through material substitution or distribution and orientation.

Title:Piezoelectric Single Crystal Applications
Abstract:A study is proposed in which the performance of an underwater acoustic vector sensor (AVS) containing conventional piezoelectric transducers is compared with that of an AVS containing single crystal piezoelectric transducers. An acoustic vector sensor is a device that measures three orthogonal components of the acoustic particle velocity in conjunction with the acoustic pressure at a single point in space. The sensor employs unimorph bender disks to measure pressure and bimorph bender disks to measure velocity. The size of each device is the same, so the chief parameters that will be evaluated are the sensitivity and bandwidth. Acoustic vector sensors are being planned for use in tactical underwater surveillance platforms that are operated by the U. S. Navy.Improve performance of tactical underwater surveillance platforms operated by the U. S. Navy.

Title:Personnel Identification and Location for MOUT Applications
Abstract:The Marine Corps is currently enhancing its capabilities in Military Operations On Urban Terrain (MOUT) in response to a clear trend toward increased military conflicts in urban settings. The MOUT capability requires new technologies, including a next-generation position-location system that penetrates building walls and tracks individuals within urban structures. This system must be compact, rugged, power-efficient, undetectable by enemy personnel, and immune from multipath and ambient electromagnetic interference. ĺther Wire has developed a communication/location system-the Localizer-that represents a system that could be optimized to meet these requirements. This system is based on Ultra-Wideband RF communications; its signals are inherently difficult to jam, have good multipath properties, and can penetrate urban structures. The Localizer represents the current state of the art and is the product of 10 years of internal and Government funded R&D. ĺther Wire's world class technical expertise will make it possible to meet/exceed the Marine Corps' requirements for MOUT within the limited scope of this SBIR effort. For Phase I, ĺther Wire proposes to 1) address key design issues (e.g., signal attenuation, multipath removal, range limitations, power consumption), 2) construct and test demonstration model, and 3) develop recommendations for further localizer development in Phase II. Phase I success will lead to a Phase II project focused upon advancing the prototype development and optimization/scale-up of the Localizer system for field demonstration. ĺther Wire anticipates developing a next-generation Localizer that will provide accurate personnel identification/location capabilities for the Marines' MOUT applications. This location technology also has diverse commercial potential in applications including asset tracking, fireman buddy systems, home navigation systems for the blind, house-arrest monitors, and automobile collision-avoidance systems.

Title:Multi Sensor Personnel Identification System
Abstract:The objective of this SBIR Phase I project is to design, fabricate, and evaluate a low cost, small size and lightweight, Multi Sensor Personnel Identification System, based on AGNC's commercial product with AGNC's worldwide pending patents, the AGNCTM-2000 CMINU/GPS Palm NavigatorTM. The Palm Navigator is based upon the coremicroTM IMU with MEMS inertial sensors. This provides a problem solution that is low power, low cost, small size, and lightweight. In the proposed system, the coremicroTM IMU is combined with an RF data link and an acoustic phased array sensor for underground and inside structures communication. The acoustic sensor, when used in a cooperative network, is utilized for interrogation, and identification of friend or foe. The proposed system is coupled with a build-in state-of-the-art GPS (Global Positioning System) chipset and exploits the GPS signals to calibrate and align the IMU when GPS is available. During those instances when no radio contact is possible, a sonar relay device is provided to furnish continuous radio contact with remote users. The techniques and systems developed in this project provide a combined military/commercial product that can be exploited in various military and commercial applications, such as Urban warfare, law enforcement, fire fighting, and emergency services equipment.

Title:Time-Modulated Ultra-Wideband Personnel Identification System
Abstract:Within the last few years low cost ultra-high precision time delays have become available, and these now make it possible to build UWB communication systems which have no carrier frequency. The only signals transmitted are pulses. With current hardware, the pulses are ź nanosecond, and a typical duty cycle is 1/500. The energy of these pulses extends approximately from .5 to 4 gigahertz, and the energy content in any conventional frequency band is far below the noise. Friendly forces (cooperative targets) will carry a small TM-UWB radio which will: 1) provide a local area communication net between friendly forces within range; 2) transmit a unique pseudo random code which will provide a private channel and which will also uniquely identify the particular radio, and 3) provide an accurate range measure from the user to any other radio. TM-UWB technology will also assist in tracking non-cooperative targets inside buildings and under ground. This will be done using Synthetic Aperture and/or Phased Array techniques. Our partner company, Time Domain Corporation is already working on a SAR based system to be used by police for tracking motion through walls, and good results have already been demonstrated.A key opportunity for TM-UWB short range wireless networks is the industrial wireless LAN market. In 1997, wired LAN equipment sales for Internet service providers alone was $18B, while wireless LAN equipment sales were a mere $213M - a gap that is beginning to close even as the market scale increases. As an example, in the health care industry TM-UWB offers a single mechanism for wireless communication to and from mobile instruments, plus it offers the ability to track the position of each of those mobile assets. TDC has raised $70 million in private funds, including funds from Sony, Siemens, US West, and Marconi plus many private investors, all of which is being expended in perfecting TM-UWB.

Title:High-Output Solid-State-Converted Piezoelectrics for Remote Vehicle Sonars
Abstract:This program will demonstrate the performance advantages of applying solid-state- converted (SSC) PMN-PT 1-3 composite transduction materials to selected Navy sonar systems which require greater bandwidth, lower frequency operation, and/or higher source levels to meet their operational objectives. The SSC materials are highly oriented piezoceramics which exhibit up to 80% the strain of very expensive piezo-single crystals, at a cost only modestly higher than traditional piezoceramics. In Phase I, MSI will (a) develop transducer concepts consistent with the emerging SSC manufacturing technology, (b) evaluate the insertion potential into selected Navy sonar systems, (c) down-select to one or more insertion opportunities based on system payoff and transition sponsor interest, and (d) develop and model prototype transducer designs for each of the selected insertion platforms. The follow-on Phase II program will focus on hardware fabrication and performance demonstration.Utilization of higher strain, higher coupling transduction materials will enable acoustic projector designs which are more compact, have increased bandwidths and lower achievable operating frequencies, and provide higher source levels. Smaller and more sensitive hydrophones will also be realized. Commercial applications include medical imaging, NDE, inkjet printing, high strain actuators, optical switching, automotive engine control, and commercial sonars.

Title:Visible, diode-array illuminator
Abstract:Diode-laser arrays operating in the visible region of the spectrum offer advantages for illuminator applications, particularly for night and water penetration capability. Recent developments in diode-laser materials allow operation throughout the visible spectrum. At this time, red diode-laser technology is more mature than the existing blue-green or violet diode-laser technology. The novel aspect of this work is the use of recent advances in monolithic silicon microchannel coolers to produce two-dimensional, red, diode-laser arrays. Cylindrical microlenses can be added to the two-dimensional arrays to create high-brightness sources. The initial work in the Phase I program will focus on the production and characterization of linear diode arrays suitable for use in 2D arrays. We will investigate the tradeoffs involved in operating at the shortest possible red wavelengths.At the conclusion of a Phase II program, we would be able to introduce stacked bars commercially. The markets that could be addressed are diode laser pump sources for solid-state lasers and materials processing using the diode lasers directly. Red diode laser arrays also address the photodynamic therapy market for cancer treatment.

Title:Blue-Green Laser Illumination System Study (BLISS)
Abstract:This project will be devoted to the development of an illuminator technology suitable for use in underwater imaging applications. While there are a number of extant technologies, we will focus on new technologies that may provide higher efficiency, lower cost, and reduced size and weight. A variety of illuminator technologies will be investigated, and compared to requirements derived from analyses of the underwater imaging application, and from platform properties. The illuminator technologies to be investigated include emitter technology, pulse power technology, and optical beam projection technology including the capabilities for varying the beam divergence (zoom). We will focus on new and emerging technologies such as Frequency Doubled Diode Pumped Vertical Cavity Surface Emitting Lasers (SHG DP-VCELS), and Electrically Pumped Two Triode Organic Lasers (TTOLs) such as the Tetracence TTOL (TcubedOL). Other candidates will be sought as well.The major advantage of this approach is to be able to illuminate underwater objects from unmanned platforms. A secondary advantage is that the sources will be low cost. A tertiary advantage is that the beam will be zoomable, allowing adaptation of the illumination to allow deeper water penetration. The use on unmanned platforms allows these systems to used in a RPV, the low cost feature allows the imaging to be performed from expendable platforms, and zoom is an additional feature that allows the platform altitude or water penetration depth to be adjusted as necessary. Thus applications such as search and rescue, airborne reconnaissance, imaging for surveillance and security, (coastal through fog), and many others would be feasible.

Title:Automatic Test Equipment (ATE) Commercial-Off-the-Shelf (COTS) Replacement for Obsolete Instruments
Abstract:This SBIR is concerned with extending the service life of existing automated test equipment (ATE) and their associated test program sets. A number of legacy ATE systems will continue to be used for the foreseeable future. The support costs for these systems continue to escalate as they near or pass their intended service lives. SBIR N01-008 addresses the problem with the introduction of commercial-off-the-shelf (COTS) instrumentation and processing equipment. DSR's proposed product can provide a form, fit, and functional replacement of the obsolete instrument that minimizes impacts to the existing ATE (hardware and software) and to the test program sets (hardware and software). The DSR proposed product includes several innovative features to capture software design requirements, to validate ATE operation after replacement, and to assist in the resolution of test program tolerance issues.The thrust of this proposal is to develop these innovations for the ATE application, define the product architecture, and to perform a top level design for a sample instrument to validate the concepts.Completion of this effort (Phase I and Phase II) will lead directly to a reduction of Navy ATE support costs through the replacement of obsolete instrumentation. Capability could also be applied to other military or civilian test systems.

Title:Automatic Test Equipment (ATE) Commercial-Off-the-Shelf (COTS) Replacement for Obsolete Instruments
Abstract:Test equipment obsolescence in Department Of Defense (DoD) Automatic Test Equipment (ATE) is a major problem. Many of these systems currently operating were designed and built decades ago. As these systems age their individual test instruments are subject to increasing failure rates. Simultaneously, manufacturer support for these devices is diminishing. Consequently, many complex ATE instruments have, or will, become the problem-prone "system degraders" tracked in ATE program reviews. New Commercial Off-The-Shelf (COTS) instruments would ideally replace these obsolete instruments. However, integration of the new COTS instruments into existing ATE systems presents several challenges. These challenges result from incompatible communication protocols and interface busses, functional differences in the way instruments operate, mechanical packaging changes, and calibration differences. This proposal presents a plan to research and develop a methodology for implementation of a translator module to act as a bridge between the new COTS instrument and the existing ATE system. This translator module, in combination with the new COTS instrument, forms a Composite Replacement Instrument that exactly mimics the function of the original obsolete instrument. This scheme will eliminate many of the integration challenges associated with replacing obsolete instruments in military ATE systems, greatly reducing the cost and complexity of upgrades. The composite replacement instrument has widespread application in civilian and military organizations utilizing ATE systems. As test equipment integrated into ATE systems is obsoleted, it must be replaced. However, integration of new COTS instruments into existing ATE systems presents several challenges. These challenges result from incompatible communication protocols and interface busses, functional differences in the way instruments operate, mechanical packaging changes, and calibration differences. The composite replacement instrument will exactly mimic the obsoleted test equipment. This provides a few benefits. First, it creates a link between legacy ATE and test instrument replacements, which improves ATE flexibility and reduces total upgrade costs. Second, it enables replacement of obsoleted equipment without modification of existing application software. Third, since the ATE interface will not change, no operator training is required. Last, since the functionality of the replaced instrument is not altered, expensive system verification tests are not required.

Title:Low-Cost Sonobuoy Geographic Position Locator
Abstract:Precise geolocation of deployed sonobuoys is a standing requirement of the U.S. Navy for improving ASW operations. Current approaches to sonobuoy localization often require close over-flight of the sonobuoy by the monitoring aircraft. This compromises the security of the aircraft, and does not provide a precision result. There is a obvious need for a Sonobuoy Geolocation System that has the following characteristics: 1) ability to operate at significant (50 - 100 mile) standoff distances, 2) geolocation of multiple sonobuoys simultaneously, 3) precise location to within 100 meters, 4) low cost @ $50.00 per sonobuoy in production, 5) low probability of intercept and detection, and 6) not susceptible to narrowband jamming. Under Phase I of this effort, ASIT will refine its preliminary system design, for precision geolocation of sonobuoys, at an extremely low cost per system. The novel solution that is proposed specifically does not incorporate Global Positioning System (GPS) receivers on each sonobuoy, but does take advantage of Direct Sequence Spread Spectrum (DSSS) signals to determine precise range and geolocation. The use of low-cost commercial wireless technology is key to the success of the program. During this effort, ASIT proposes to make the design a reality by building a prototype sonobuoy geolocation system that will be ready for demonstration to the customer by the end of the Phase I effort.To address both Government and commercial needs for low-cost, robust, precision geolocation, this effort will use spread spectrum signal processing technology combined with exisiting commercial wireless components to provide a reliable geographic position locator.

Title:Low-Cost Sonobuoy Geographic Position Locator
Abstract:Under this proposed SBIR effort, NAVSYS will develop a design for a low cost sonobuoy position locator using GPS geolocation technology. GPS has been proposed as an alternative for sonobuoy geolocation, but the environment and DoD security requirements leads to problems with a conventional GPS approach. SAASM compatible OEM modules that prove P(Y) code tracking capability are prohibitively expensive for "disposable" applications such as sonobuoy geolocation. NAVSYS have developed a low cost tracking technology, TIDGETTM, which uses a client/server approach to reduce the functionality needed on the GPS geolocation sensor. This has been previously demonstrated with C/A code operation, installed on a sonobuoy provided by DERA Farnborough. Under this SBIR effort we propose to the develop a P(Y) code TIDGET architecture suitable for installation in US sonobuoys. A feasibility study will be performed to very the performance, physical and cost goals, and test results will be provided demonstrating the P(Y) code geolocation performance using live GPS satellite signals. Under Phase II, a prototype P(Y) code GPS sensor integrated with a government furnished sonobuoy will be .delivered for field testing. The low cost P(Y) TIDGET sensor will provide a cost effective geolocation alternative for sonobuoy applications while meeting the DoD PPS security requirements. Other applications include GPS tracking of radiosondes, for wind-finding support of DoD missions, and geolocation of low cost "smart-sensors" deployed for surveillance applications.

Title:Large Format Resistive Arrays (LFRA) for Infrared Scene Projectors (IRSP)
Abstract:This proposal is to demonstrate the feasibility of a larger format resistor emitter array, greater than 544x672 pixels. Mega-pixel IR/EO emitter arrays allow higher resolution imagery to be utilized in the testing and performance evaluation of advanced IR array sensors. As both the pixel count and the framerate capability of these sensors increase, the data rate required by the large emitters strain the state-of-the-art. This large format array is to be compatible with, and test, a next generation high-speed scene projector drive electronics, being developed via a FY-1999-2 SBIR topic program, capable of processing real-time image data at rates exceeding 420 MB/sec, roughly 200 Hz for a 1024x1024 array. Use with the GFE electronics set dictates that the "array" for this proposed SBIR effort is defined as all of the necessary components and assemblies from the output interface of the GFE drive electronics to the emitting pixel itself. Besides transforming the digital electronic data into a compatible set of integrated analog voltage singles to drive the array, an additional set of requirements will be dictated by ramifications from the larger array size, packaging needs, and potentially new operational regimes.The large format resistor array increases, simultaneously, the total field of view and resolution with which infrared scenes can be projected to test hardware in the loop simulations. The image quality is realistic to the point that todays IR seekers cannot distinguish the difference, allowing for acurate testing in a cost saving simulation versus flight test. Many hundreds of tests can be executed for the cost and time involved in a single flight test.

Title:Large Format Resistive Arrays (LFRA) for Infrared Scene Projectors (IRSP)
Abstract:Indigo Systems proposes to design and produce a 1024x2048 format high performance Large Format Resistive Array (LFRA) for Infrared Scene Projector (IRSP) applications. The proposed project will leverage Indigo's recently developed 512x512 MIRAGE commercial off-the-shelf (COTS) micro-emitter array technology. Additionally, to the extent possible, our current development activities for a 1024x1024 LFRA will be leveraged to insure project synergy and success. PHASE I: During phase 1 Indigo proposes to advance the 1024x2048 LFRA design from concept through the preliminary design stage of the Indigo detailed integrated circuit design process. During this activity the requirements and specifications for the device will be developed. Complete schematics of the different functional blocks and signal chain will be simulated and evaluated. The outcome of this phase is the Preliminary Design of the ROIC, including concepts studied and an interface description for a high bandwidth scene projector system during. This effort will last 4 months. PHASE I Option: The Phase I continuation (Phase I Option) will last 2 months during which time Indigo will begin the detailed design process for the 1024x2048 LFRA. The outcome will be an Interim Design Report. The objective of the proposed 1024x2048 LFRA development activity is to begin to produce the next generation in LFRA devices for scene stimulation. The current generation of IRSPs using resistive arrays contain on the order of 512x512 emitter pixels. These devices are introducing performance limitations in the testing of many modern currently fielded sensor systems. They do not provide the necessary resolution and FOV coverage to adequately test advanced sensors that are currently under development (i.e., advanced target acquisition sensors, threat warning sensors, IR search and track sensors, surveillance and reconnaissance sensors, and missile seekers). This project will facilitate the transition of existing mature resistive array technology to larger format resistive array based IRSPs for testing next generation IR sensor systems that will require testing in FY01-03.

Title:Web-Based and Traditional Classroom Lesson Design Guide
Abstract:The purpose of this SBIR is to develop and evaluate a Web-based instructional tool (WBIT) that can be used by officers and enlisted personnel to design courseware for traditional classrooms and distance learning environments. The WBIT will be organized around the five phases of ISD/SAT (analysis, design, development, implementation, and evaluation), and will provide the user with access to state-of-the-art principles of effective lesson design. The latter will reside in a powerful relational database management system forming the knowledge engine of the system. The primary products of Phase I will be a well-developed database of instructional design principles, a demonstration module, and the functional requirements for a complete system. For Phase II, the literature review will be expanded, functionality for the system will be enhanced to encompass all five phases of ISD, and experimentation with various configurations of web-hosting will be employed. The resulting product will be a powerful web-based instructional tool that can guide even novice developers through the complex ISD/SAT process.Benefits of the tool will include faster courseware development, more effective and interesting courseware materials, greater standardization and quality control of courseware, and greater integration of effective classroom techniques with the latest developments in web-based training. These attributes will be combined to produce a more optimized learning environment for student users. Upon conclusion of Phase II, the tool may be deployed either as an adjunct to MIL-HDBK-29612-2 or as a stand-alone system. The principles embodied in this system may be effectively exploited within any industry where a Systematic Approach to Training (SAT) is employed, such as Power Generation, Transportation, and Process Control.

Title:Guide for Instructional Design (GuIDe)
Abstract:Technological advances (e.g., advanced electronic classrooms, video tele-training, and web-based curricula), quickly being incorporated into instructional environments, offer the instructor increased flexibility. To maximize learning we must explore not only technology but the multiple factors that impact training effectiveness. It is not enough to simply incorporate the most recent technological advances into traditional instruction, for doing so does not guarantee an optimal learning, or training, environment. Instead, planning an instructional program requires careful selection of the optimal technology and training mode out of the myriad available. For our Phase I effort we propose to develop a thorough taxonomy of learning issues, based on contemporary cognitive theory and practical training issues, that defines each issue, describes when it is most likely to be a problem and outlines what can be done to maximize the effectiveness of the instruction; this taxonomy will be used to develop a proof-of-concept web-based Guide to Instructional Development (GuIDe) that will help instructors develop the optimal training/instructional environment for their circumstances. Our unique inter-disciplinary combination of expertise and experience, ranging from innovative military training research to hands-on teaching experience in web-based environments, makes us exceptionally well qualified to address the challenge of creating an instructional development guide.A flexible and upgradeable web-based tool instructors can use to develop the optimal instructional environment for their circumstances will be valuable to government, academe, and industry as instructor?s seek to use only that technology that enhances learning.

Title:Instructional Designer's Workbench
Abstract:Intelligent Automation, Inc. (IAI) proposes to design The Instructional Designer's Workbench (IDW), an expert system that incorporates an extensive set of rules and heuristics derived from (1) research literature; (2) the advice of successful, expert instructors; and (3) policy and parameters set by the Navy. This automated tool will support courseware authors by advising the author on relevant cognitive issues and learning principles and how they should impact design of instruction. An instructional designer will use this tool as he/she considers and implements the design for an instructional program. IDW complements the Instructional Systems Design (ISD) process, advising the designer throughout the stages of the process. As a tool that provides expertise in pedagogy and psychology, IDW will strongly influence the quality and effectiveness of instruction in environments where courseware developers may not have a level of theoretical expertise to inform the development decisions they are asked to make. Regardless of the instructional delivery platform (including classrooms), IDW will be designed to answer queries about design, using cognitive learning principles, pedagogy, and relevant examples of instructional intervention. We believe that the potential for commercialization of our product is closely tied to the rapid growth of the computer-based training (CBT) and distance learning markets. As a participant in the Advanced Distributed Learning Initiative sponsored by OSD, we are keenly aware of the explosive growth and interest in distributed learning systems used in a distance-learning context. We believe that the issue of quality becomes critical in a Web environment, where materials "published" directly by authors have not been subject to the same rigor of professional quality review that most commercial products undergo prior to publication. Therefore, our product will also be marketed to purchasers of CBT and distance learning technologies as a method of reviewing courseware for the quality of its design in terms of cognitive science attributes.

Title:Web-Based and Traditional Classroom Lesson Design Guide
Abstract:Current military handbooks primarily focus on instructor-led training. This project will develop an Instructional Design Advisor and Guide for computer- and web-based training. Phase I will be an analysis of the existing literature and initial recommendation of an effective methodology/algorithm that will: 1) recommend an effective instructional method(s) based on situational factors and 2) provide clear, concise guidance on how to design the interactive courseware for a particular lesson. The analysis will compare areas such as instructional technology, learning theory, cognitive psychology, distance learning, human-computer interaction, and lessons learned from practitioners. Research gaps will be identified. Phase II will develop the decision matrix and specific design guidance. The design guidance will be provided in Military Handbook format and also delivered in a computer-based decision aid and instructional design tool. A Phase III effort would focus on developing a knowledge-based agent advisor.Distributed learning technologies are critical components of the goal to provide learning, any time, anywhere. However, the rush to convert courses to the computer or Internet has put the focus on delivery rather than design. The Instructional Design Advisor will provide novice designers with the information they need to develop computer-based lessons that are instructionally effective.

Title:The Development of an Electrical Wire Chafing Protective Technology for Aircraft
Abstract:This Small Business Innovation Research Phase 1 project describes a patented sensor technology that BPW Incorporated has developed. This technology which is called "ShortWatch," can offer significant improvements in electrical safety. The sensor consists of a temperature and mechanical damage-sensing strip distributed along the length of an electrical wire or distributed along the surfaces of an electrical component. The sensor strip performs three tasks: (1) It senses an overtemperature condition at any point along the length or surface of the electrical wire or cable, (2) It acts as a mechanical damage sensor by sensing continuity in the sensor strip distributed in the electrical cable insulation, (3) It can monitor or check the insulation effectiveness remotely without disturbing or accessing the electrical wiring. Mechanical damage (or deterioration) of the insulation or casing which might expose the energized conductors will result in loss of continuity of the sensor strip and would provide an alarm and/or interrupt power to the component, or warn the operator of a potential problem. This particular SBIR project focuses on developing the technology to protect existing aerospace wiring from chafing or external mechanical damage.We believe that the proposed "ShortWatch" technology would have very broad usage in both aerospace and non-aerospace applications. We foresee the initial applications of this technology in high-risk, high-value applications, which would include aerospace, nuclear power, and oil and gas electrical apparatus. The application of this technology for the residential and low-risk industrial usage would come later as the development costs were amortized.

Title:Wire Chafing Diagnostic Technology for Aircraft
Abstract:IDI proposes to investigate passive diagnostic approaches for the detection of wire chafing on the aircraft well before exposure of the bare conductor. Conventional methods involve assessing the reduction in dielectric breakdown of the worn insulation, time domain reflectometry, or other methods that require disconnecting the cable either for access or for circuit protection. The proposed approach uses passive sensors to monitor the chafing action without removing or disconnecting the wires under reviewuation. Noise generated by the chafing can be statistically related to structural vibrations, and the chafing source can be located through signal correlation techniques. Phase I will investigate candidate passive diagnostic approaches. Lab testing on wires in a simulated chafing environment will be performed to validate the approach. Based on the test results, a down select of the preferred measurement approach will be made. Phase II will develop a functional prototype and in-situ demonstration. During the commercialization phase, IDI will work with established HUMS manufacturers to integrate the wire chafing technology into an aircraft health monitoring system. Incorporation of the in-situ wire chafing diagnostic technology into an aircraft health monitoring system will increase the safety and readiness of both military and commercial aircraft fleets. Signification life cycle cost savings could be realized with a reduction of aircraft accidents as well as reduced downtime for inspection, maintenance, and repairs. Such a system could be commercialized to detect wire chafing in space, sea, and land vehicles as well.

Title:THERMOGRAPHY TO THE RESCUE: WIRING SYSTEMS DIAGNOSTICS AND PROGNOSTICS
Abstract:An urgent need exists for diagnostic methods to interrogate wiring of a Navy air vehicle on demand and assess its current health. While naval craft remains in an active status, its wiring materials, particularly insulation, interact with a complex operating environment which accelerates its aging/degradation, especially in the hostile engine environment. Ability to determine if the wire has undergone excessive degradation to warrant its replacement has direct implications on (i) aircraft operation safety and (ii) maintenance cost and the cost of ownership. We propose to place a miniature infrared sensor in a suitable location within each CRITICAL zone or compartment of an aircraft. IR sensor will continuously monitor all the wiring in that zone and send real time data to the flight crew via a single video cable. Under normal flight conditions, any defect in the wiring would manifest itself as a hot spot. Such a thermal disturbance would be instantaneously detected by our high resolution IR sensor and a signal sent in real time while in flight to alert the crew to a wiring problem in that specific area. This instantaneous determination of defects would eliminate the need for ground personnel to spend hours trying to find the defect. Visual images of wiring problems may be recorded on a pocket size videorecorder to monitor the rate of progression of the defect and then "objectively" determine the remaining useful lifeMilitary and commercial aircraft maintenance; chemical plants with explosive and/or corrosive environment; boiler rooms in public buildings; nuclear power plants

Title:Mid-Air Collision Avoidance System (MCAS) Using Mode 5
Abstract:FTI will research the present need for MCAS by integration of an IFF Mode 5 waveform to provide collision avoidance capabilities for the Navy platform. We will evaluate current transponder hardwares to determine the change/modification requirements necessary for such integration. Also included will be studies of current military systems, hardware and software currently in use, and the technical and functional limitations and restraints required to implement Mode 5 MCAS functions into the IFF transponders. We will provide our solutions in a functional block diagram, including the necessary interfaces and options selected.The commercial potential of this research will be to provide collision avoidance via MCAS using Mode 5, for general, commercial, and NATO aviation. This will provide for greater safety world-wide, and enhance NATO applications as well as increase sales potential to foreign militaries and individuals.

Title:Mid-Air Collision Avoidance System (MCAS) Using Mode 5
Abstract:Scientific Research Corporation (SRC) proposes to use the Identification Friend or Foe (IFF) Mode 5 Waveform set in the design of a secure high capacity Mid-Air Collision Avoidance System (MCAS). The investigation into the design of MCAS will focus on incorporating the functionality of a collision avoidance system (CAS) upon an existing Government approved Mode 5 IFF Transponder, such as the BAE System's CXP unit. Therefore, the implementation strategy for MCAS is via software. MCAS will provide security provisions such that the data link can not be easily exploited, constant monitoring of the situational awareness of the platform's safety zone, and transparency as not to affect the operational capabilities of the platform that MCAS will be installed on. MCAS will also provide a high degree of "user-friendliness" as not to interfere in any manner with the pilot's ability to successfully complete the intended mission. By embedding MCAS into a Government approved Mode 5 IFF Transponder no additional equipment needs to be installed onto the platform such as the F/A-18F. This design approach offers minimal risk to the Government by minimizing the costs associated with installing a stand-alone commercially available CAS system such as TCAS that offers no security provisions.Since MCAS will be embedded into a Government approved Mode 5 IFF Transponder, MCAS immediately can be used in joint U.S. service training exercises and operations with negligible multi-service integration concerns as well as between U.S. and armed forces of current and future members of NATO. MCAS can also be installed in privately owned aircraft as well as small and mid-size aviation firms without major retrofits to their aircraft or without causing any security breaches for military platforms.

Title:Environmental Assessments and Mitigation of Naval Operations
Abstract:The objectives of this research are to research and design the necessary components of an environmental impact assessment software suite and to provide modeled environmental impact assessment results for selected sites. The research will focus on the impact of active acoustic emissions on marine mammals in the oceans. In the research and design portions of the study, AHA will examine the pertinent marine mammal characteristics and develop a database for those characteristics; retrieve and perform statistical analysis of environmental acoustic characteristics of the oceans, including temporal, spatial, and directional variability; investigate active sound propagation and procedures for the assessment of its impact on marine mammals; and incorporate the above items in the design of a web-enabled environmental assessment decision aid software tool. In the assessment portion of the research, AHA will perform acoustic modeling to produce representative summaries of marine mammal impact for selected sites.Many organizations within the U.S. government and private industry could make use of the environmental assessment software tool designed as part of this research, in order to ensure compliance with applicable laws. Examples include companies involved in drilling and recovery of natural resources, underwater construction, oceanic transportation, and marine geophysical and seismic surveying.

Title:Environmental Assessments and Mitigation of Naval Operations (Air and Surface)
Abstract:A marine environmental compliance and analysis web-enabled toolset will be designed based on extensive prior experience with web and GIS enabled technologies in an environmental analysis and documentation environment. The objective of this research project is to develop an environmental tool capable of efficiently ensuring that the Navy has limited environmental impacts on the marine environment, while maintaining its force readiness and testing and evaluation programs. The toolset will consist of two parts. Part 1 will use existing data, acquisition policy documents, regulations and document design specifications to produce draft NEPA documents based on project requirements that are comparable to previous proposed actions. Part 2 will provide analysis tools for evaluating systems, sub systems, and technology at various stages in the acquisition lifecycle and the corresponding actions that are planned (tests, fielding, OPEVAL, etc). Two key features define this product. One: all the data is cross-referenced by the action or equipment being used, the resource impacted, the location of the action, time of year, the environmental standard operating procedures and regulations. Two: all documents and methods included at the outset will reference approved data, so that new documents can be built using approved language and methods. As changes occur in regulations, approved language and methods, these data will update automatically with minor software enhancements.Broad applicability for the resultant product is anticipated, both within the Navy and in the general environmental community. Any organization doing environmental analysis and documentation will benefit directly from a tool that allows quick and accurate access to previous related documentation. Although the content would change, no release of Navy information would occur, and the design would be useful elsewhere.

Title:Environmental Assessments and Mitigation of Naval Operations (Air and Surface)
Abstract:SBIR N00-014 addresses the problem of developing a tool that can provide environmental assessments in support of the deployment and operation of active sonar systems. DSR's proposed product will initially target support of the SH-60R Airborne Low Frequency Sonar (ALFS). The design of the product will be modular so that functions that address unique SH-60R characteristics are easily separable from the basic environmental assessment capability. The proposed environmental assessment capability is based on an existing product that tracks both the acoustic source and the animals' movements, estimating the incident sound intensity and resulting impact on the animals. The product interfaces to a propagation model (selected based on the particular sonar system) to characterize the acoustic propagation and combines this information with models of the migration habits, behavior and physiology of various animal species. Incorporation of information such as ocean characteristics, weather patterns and actual animal sightings are also included in the design. The product is modular enough to accommodate any acoustic propagation model and to support other sonar systems simply by modifying the functions that interface the environmental assessment functions to the unique processing algorithms, interfaces, communication channels and OMI of the selected sonar system.Completion of this effort (Phase I and Phase II) will result in development of a tool that provides an environmental assessment capability to support deployment and operation of the SH-60R acoustics system. With appropriate interface modifications, this same capability could be provided to other U.S. Navy sonar systems and commercial systems that use acoustic energy to explore or characterize the ocean

Title:Enhanced Crash Survivable Flight Incident Recorder (ECSFIR)
Abstract:Proposed is a study of incorporation of aircraft incident recorders and Structural Data Recorder Systems (SDRS) into an open architecture wireless network. This Enhanced Crash Survivable Flight Incident Recorder (ECSFIR) will improve flight safety by providing better information to accident investigators and reduce aircraft maintenance costs by improving diagnostics and automating maintenance schedules. Invocon will conduct comprehensive investigations into the ECSFIR system expectations and technical requirements. Consideration will be given to the incorporation of microminiature wireless sensors similar to those previously developed by Invocon. Programmable Surface Acoustic Wave (PSAW) correlators are under investigation by a team including Invocon, Sandia National Laboratories, NASA, and the Air Force Research Lab; in the ECSFIR, they will provide simultaneous RF communications giving the RF data bus extremely high-speed and reliable transmissions. The system will have an open architecture for future expansion and portability between aircraft. Invocon will provide at the Phase I conclusion a report detailing conceptual designs and configuration structures for all ECSFIR elements. Invocon proposes a Phase I Option to demonstrate a prototype wireless ECSFIR aboard a Naval Aircraft. This system will perform most of the major proposed requirements and provide a proof of concept and predetermination of some Phase II obstacles. Commercial airlines are always seeking ways to reduce costs and increase safety. It is likely that the reduction in aircraft maintenance costs alone will demand a system like the proposed ECSFIR. But the market for this type of system extends far outside the aviation industry. In any setting where machinery performance is essential, and failure induced stoppage greatly affects profit, a health maintenance system is imperative and cost effective. Commercial equipment from all types of industry could benefit from component monitoring and performance evaluation: oilrigs, tractor-trailers, locomotives, and industrial equipment. A wireless health monitor like the proposed ECSFIR provides two major benefits over current monitoring systems: convenient retrofitting and acquisition from previously inaccessible areas. Often equipment is designed with unknown weaknesses, and the built-in sensors do not monitor all the critical components. Retrofitting with current wired sensors is not cost efficient, and at times impossible. A wireless system allows quick non-intrusive installation on any component. The incorporation of the microminiature wireless sensors adds one more way to reduce installation complexity and costs. In addition the ability of remote processing paves the way for real-time health monitoring and operator warning notification of potential failures or the end of the life-cycle approaching.

Title:Digital Data Download (D3) with Crash Survivable Memory
Abstract:This proposal presents innovative research that will result in a multi-purpose, crash survivable, universal flight information system and data recorder (UFDR). The UFDR will digitally process and record structural, engine/propulsion, electrical/avionics, environmental, exceedance, and event data to crash survivable memory with capacity for terrabytes of data. It will have advanced features for processing and storing voice and data from Integrated Mechanical Diagnostics and data from Aircraft Health Monitoring Sensors. This is a ş°single boxş˝ solution that offers significant function, weight, and total ownership cost advantages over current technology. The UFDR will incorporate a very high-speed transceiver with data compression algorithms that will download hours of flight data in a few minutes making it unnecessary to spend millions on ş°black boxş˝ recovery. The architecture is backwards compatible to legacy aircraft as well as future aircraft. Reduced parts count and lower power consumption will dramatically improve fielded reliability. Field Programmable Gate Arrays will provide upgradeability, programming flexibility, flight data sensor management, enhanced reliability and product longevity. This innovative approach is low cost, modular, expandable and configurable to support legacy, new and undefined requirements and communication protocols.The proposed UFDR offers reduced weight and significant cost saving with increased functionality combining the conventional Air Data Recorder, Health Usage Monitoring System, and Integrated Mechanical Diagnostics units. Based on successful completion of the UFDR research, MSI will prototype, manufacture and market the UFDR to the military and civil aviation communities. We anticipate developing strong marketing relationships with aerospace, avionics and aircraft manufacturers, owner/operators and aircraft servicing organizations. These relationships assure that the UFDR is compatible with state-of-the-art avionics design.

Title:Flight Anomalous Event Recorder Information Technology Open (FAERITO) Digital Data Download (D3)
Abstract:Physical Optics Corporation (POC) proposes a new approach to Digital Data Download (D3) with Crash Survivable Memory. Based on this approach we will develop a system called Flight Anomalous Event Recorder Information Technology Open (FAERITO) D3, to collect and quickly download hours of video, audio, and sensor diagnostic data. This system will use 3400 g crash-survivable PCMCIA packaging cushioned with aerogel, which is an outstanding thermal insulator and 3400 g crush protector. The FAERITO system will be compatible with SDRS, CFSIR, and FLDR, all of which will be integrated into the single FAERITO package. The crash-survivable-memory FAERITO system will be based on non-volatile newest-generation multi-Gbyte flash memory and POC's soft-computing and soft-communication (SC2) hypercompression technology, which offers up to 4000:1 compression for TV-class video. It will enable automatic recording of anomalous events (both spatial and temporal) without a priori knowledge of the specific nature of these events. FAERITO will also incorporate wireless sensor LAN technology that is still unknown to present commercial (or military) 2G and 2.5G wireless telephony, and which is equivalent to futuristic 3G wireless units. It will provide capabilities to transfer TV-class imagery, video, imaging radar, teleconferences, and other interactive and IP video information.Many commercial applications will benefit from the diverse components and system features of FAERITO information technology, including: emerging generations of interactive wireless video (3G wireless phone), IP-video, cellular video phones, e-commerce security, video surveillance, video games, telemedicine, robotics, physical protection, video conferencing, MPEG-4, and finally, civilian FAA black-box flight data recorders.

Title:Development of New Processes for the Refurbishment of Infrared Search and Track (IRST) Germanium (Ge) domes
Abstract:A proprietary method is analyzed for the refurbishing IRST germanium domes that have been damaged in flight operations in adverse hostile environments which include particulates such as sand, rain., aerosols, etc. The COI technique involves removing the damaged surface and then restoring the domes on a production basis to their original focal length performance specification. Improved coating machine technology is evaluated in the application of Amorphous Diamond Like Carbon (ADLC) via a process known as Ion-Assisted Filtered Cathodic Arc, IFCAD, process coating technology to Germanium substrates operating in the 7.5 to 14 micron band. The result is a low cost refurbished dome that has a harder outer coating than the original dome and hence longer expected lifetime. The proposed research will benefit not only government programs but will also benefit existing work currently at Computer Optics Inc. The technology developed under this proposal will have direct application to laser optics, the electric power industry and construction.

Title:Development of New Processes for the Refurbishment of Infrared Search and Track (IRST) Germanium (Ge) domes
Abstract:A procedure has been developed to refurbish hemispherical infrared (IR) windows designed for use on the Infrared Search and Track (IRST) System. The two stage program will enable repair of the surface coated germanium (Ge) windows, more commonly known as domes, which have failed to meet IR transmission and focus specifications. Failure to meet specifications is due to a high density of pits in the aperture area generated from exposure to adverse environmental conditions at high velocities. Stage 1 (immediate) involves removal of surface material, which will result in a finished dome that meets transmission requirements with 4.7% maximum deviation from the specified focus. This process may introduce slight image aberration, which may or may not be within acceptable tolerance of the optical system. A dome refurbished using stage 1 will be delivered at the end of SBIR Phase I. Stage 2 will implement a process to add Ge to the dome surface in an amount necessary to allow resurfacing to the original design dimensions. This process would return the dome to the like-new operational performance. Feasibility for stage 2 will be demonstrated during SBIR Phase I. Delivery of domes refurbished using stage 2 would occur during SBIR Phase II. The electric power utility industry utilizes IR sensors in the same bandwidth as the IRST sensor to perform evaluation on above ground power transmission lines for insulation leaks. These leaks result in power transmission loss costing the utility companies millions of dollars annually. To identify failures in power line insulation, public utilities use specially configured aircraft that fly over the nation's power lines using IR sensors to detect the leaks. The location of the failed insulation along the power line is detected and the information sent to the power company for repair. The IR systems used in the utility company's aircraft have the same type of IR window used in an IRST system. While less harsh (lower speed), the utility company aircraft's IR system is subject to much of the same environment as the F-14D IRST. The utility companies' IR systems experience more usage than the IRST. Further, flights are made at lower altitudes where airborne particulate matter has a greater opaqueing effect on the IR window. Resulting failure of the IR window occurs at least as often in the IRST. Development of a refurbishment process can be directly applied to this particular commercial application.

Title:Shallow Water Bottom Characteristic Measurement Sensors
Abstract:This SBIR proposes the design of an expendable sensor system for in-situ measurement of bottom characteristics such as bottom loss and bottom back-scatter. The data would be inputs to acoustic performance models such as Tactical Decision Aids (TDAs). This sensor system will obtain real time environmental data in shallow water to optimize the deployment and performance of acoustic sensors such as Air Deployable Active Receiver (ADAR), Advanced Low Frequency Sonar (ALFS), and Directional Command Active Sonobuoy System (DICASS). The unique features of this proposal concept are near bottom sensor strings combined with near bottom small sources to obtain bottom characteristics at low grazing angles without the need for large high power sources. The sources proposed here are only 170 (dB//uPA2 in a one-octave band) compared to the 200 to 215 (dB//uPA2 in a one-octave band) source level required by near surface measurement systems. The proposed system also utilizes an in-buoy processing system to compute bottom loss and bottom back-scatter from measurements of signal level and arrival times. Only results that can be directly input to TDA will be transmitted to tactical aircraft adding no additional processing burden on the tactical aircraft system.This proposed device will satisfy a critical need for a rapid response environmental measurement system to acquire data and in-situ measurements for accurate on site tactical decision aids, nowcast active sonar predictions and buoy deployment geometry optimization, and perform this task in a more environmentally friendly manner with smaller sources. This development will allow the measurement of ocean bottom parameters safely at sites close to shore and at sites which are off-limits to the current large source level system. Commercial markets include offshore environmental bottom sediment data collection, coastal environmental studies and potentially off shore oil exploration.

Title:Shallow Water Bottom Characteristic Measurement Sensors
Abstract:Detailed knowledge of the operational environment can be exploited to improve the capabilities of active sonar detection and classification systems. The deployment geometry, transmit bandwidth and averaging time can all be set to optimize detection performance given the detection system has a detailed knowledge of the operational environment. In addition, more detailed knowledge may also provide target classification clues derived from the received echo shape. The environmental data gathered on station could be integrated into a tactical decision aid (TDA) that is run prior to the start of the Anti Submarine Warfare (ASW) search phase of the mission. One of the more difficult parameters to measure in-situ is the bottom scattering strength vs. grazing angle. Knowledge of the bottom scattering strength is critical in shallow water operation where the bottom reverberation is the dominant source of interference. This is especially true in downward refracting environments. The bottom scattering strength is difficult to measure because bottom reverberation is a function of a number of complex parameters such as the transmission loss to the bottom and the bottom loss verses grazing angle curve. This SBIR solicitation (N01-017) proposes the development of a new sensor capable of making a bottom loss measurement. To keep development and production costs manageable, this new sensor will leverage heavily on existing air deployed sonobuoy technology. The proposed sensor would be used in conjunction with existing sonobuoys already in the Navy's inventory. In this SBIR solicitation we shall address the methodology and feasibility of such a technique.The product of this SBIR will have a direct impact on existing and proposed air deployed ASW search systems. The proposed system could be used either prior to the deployment of or in conjunction with existing or planned ASW search sensors. The benefit to the fleet will be an increased awareness of the operational environment leading to more effective mission planning and execution. The proposed sensor could potentially be marketable to non-military government agencies for the purpose of harbor monitoring and surveillance. More specifically, we see a potential market to drug interdiction agencies needing to detect and classify small vessels that may escape detection by radar systems yet have strong acoustic signatures.

Title:Semi-Active Side-Lateral Engine Mounts for Control of Vibration and Shock Loading
Abstract:The objective of this proposal is to define a program that will investigate the E-2C vibration and shock dampening side engine mount requirements and develop an innovative semi-active vibration and shock mount system for the E2C aircraft's side lateral mounts. Currently, there is no system available that incorporates both vibration nulling and appreciable shock alignment in a compact package. FFF is proposing an innovative hybrid MR concept that can meet the E-2C's requirements in a package that can withstand the aerospace environmental conditions and the installation constraints.New semi active mounts can be used on many of the curent classes of aircrafts and helicopters. The combination of improving vibration isolation while maintaining static alingment under shock loads can be applicable to many commercial and miliatry programs including land vehicles and marime applications.

Title:Side lateral Engine Mount
Abstract:The key innovation of this proposal is combining an MR fluid damper with a stiction based shock absorber to provide adaptive damping and shock absorption as a means to upgrade the current side lateral engine mount which provides no vibration isolation. Our concept is focused on minimizing the certification process for use on E-2C and C-2A aircraft, and therefore minimizing the time and cost to being installation on actual Navy aircraft. The proposal also describes the control algorithms which will allow the system to be totally autonomous. We have organized the proposed project so that by the end of Phase 1 we will be able to test the key aspects of the system and assess the benefits with respect to adaptive damping based on MR fluid. By the end of Phase 2 we will have a fully integrated adjustable damping and shock absorbing side lateral engine mount which would be ready to begin the certification process.Our first commercialization focus will be to achieve a system which the Navy will use on E2-C and C-2A aircraft. Later commercialization will focus on other aircraft adaptive isolation mounts, and then on applications beyond aircraft.

Title:Smart Engine Mounts with Energy Managing Continuous Structural Elements
Abstract:Vibration and shock attenuation is the focus of this SBIR project. We offer to demonstrate the feasibility of the Smart Engine Mount with Energy Managing Continuous Structural Elements system concept suitable for use in airborne vehicles such as E-2C aircraft. Excess vibration energies will be channeled and attenuated inside the Smart Engine Mount whose continuous and connected elements will have energy flow control and energy managing capabilities. This innovative Smart Engine Mount concept may be used as an effective semi-active and hybrid barrier between vibration energy generated by an engine and sensitive optical and electrical components inside an aircraft. The entire smart mount will be composed of three main layers in which semi-active and hybrid energy-managing elements will be embedded. In other word, vibration and shock disturbances injected into the engine mounts will be confined, diverted, converted, absorbed, steered, and dissipated using embedded passive elements and active actuators. It is this energy-managing feature of the smart mount that makes our concept unique and effective. In addition, our approach will be distinct when compared with conventional discrete mounts because our smart mount will be made of continuous elements that are interconnected to make the entire mount system significantly more effective. Finally, the semi-active feature of the proposed Smart Engine Mount will have the capability of changing it stiffness and/or damping rates in an on-off manner to accommodate operational changes.More effective engine mounts may be used on many of the current commercial piston and turboprop aircraft as well as helicopters. The combination of improved vibration isolation while maintaining static alignment conditions under shock loads will also be applicable to better isolating a variety of military and commercial power trains from the rest of the vehicle. In addition to airborne types, these vehicles include passenger automobiles, commercial trucks, marine vehicles such as submarines and surface ships.

Title:Advanced Rotorcraft Shipboard Landing Aerodynamic Interference Software Modules
Abstract:Shipboard landing presents a multitude of problems for rotorcraft that must be addressed to assure safe operation. The interaction of the rotor downwash with the ship's deck and the interaction of the ship airwake with the rotor are two key areas of this "Dynamic Interface" that must be fully evaluated to establish limits on shipboard operations for rotorcraft. The high cost and inherent danger of shipboard testing have been major impediments to supporting the Fleet in this critical area. The use of simulation to provide a Rotorcraft Shipboard Operational Limit Prediction Tool will enhance flight test productivity, reduce cost, and increase the safety of flight test operations. Advanced Rotorcraft Technology Inc. (ART) has developed FLIGHTLAB, a comprehensive rotorcraft modeling tool, and has added extensive utilities to support flight testing and validation. Under this SBIR, ART proposes to extend the aerodynamic and interference modeling in FLIGHTLAB to fully encompass the shipboard landing environment and to incorporate automated prediction of the Rotorcraft Shipboard Operating Limits and a prototype Maritime version of the ADS -33 Handling Qualities analysis. The resulting Rotorcraft Shipboard Operational Limit Prediction Tool will greatly facilitate the test and evaluation of helicopter shipboard landing. The tool developed will expedite rotorcraft/ship qualification, benefit both military and commercial rotorcraft shipboard landing training, and facilitate commercial airline landing zone planning.

Title:A Real-Time Airwake Model for Dynamic Interface Simulation Support
Abstract:A novel physics-based real-time computational method of representing the airwake of Navy ships to support rotorcraft shipboard landing simulation studies is proposed for research and development. In this method, the unsteady ship airwake is modeled using vortex doublet elements shed from sharp edges of the ship superstructure, and the approaching rotorcraft is described by a panel-based fuselage model and freely distorting wake analysis. Use of fast panel methods and octree sorting structures may allow this highly complex wake representation to be calculated in real-time, using networked computers in a parallel computation environment. The airwake model representation provides an appropriately detailed level of fidelity to capture handling qualities features of importance to shipboard rotary-wing aircraft operations, while maintaining real-time computation throughput. This approach promises to revolutionize "dynamic interface" simulation by combining physics-based models of helicopter flight dynamics, rotorcraft free wake representations, unsteady ship airwake generation, and, optionally, ship motion dynamics. The resulting simulation environment may be used to quantify operational shipboard approach envelopes without the considerable time and expense of at-sea testing.Software developed under the proposed program would drastically reduce Navy costs associated with at-sea qualification testing of various ship/rotorcraft combinations, by replacing a significant number of tests with computer simulation. The airwake software would also enhance the safety of commericial helicopter pilots operating from offshore oil platforms or in urban environments when used with flight simulator systems.

Title:Software Cost and Schedule Estimating
Abstract:There is an acute need for the development of software estimation techniques that will allow government organizations and contractors to realistically determine the scope of software development projects up-front and to refine these estimates and make project decisions during development based on quantified estimates and risk assessments. This information is needed on new developments, upgrades and maintenance for the variety of languages and methods used within NAVAIR and the Department of Defense, as well as a broad range of other government and commercial organizations. Research by the Navy and others has identified realistic software estimation as a "Best Practice". Galorath proposes "plug-ins" to its commercial SEER models that will considerably enhance the state of the art in software project estimation and tracking. Plug-ins will include data mining and other techniques, a database of project histories and trends, as well as tighter integration of project management functionality. Once this SBIR is successfully completed, users will be able to: ˙ Estimate software development cost, schedule, and risk with more accuracy, early in the acquisition cycle. ˙ Better evaluate risks and make informed decisions both early and throughout the project. ˙ Better prepare project "estimates to complete". GartnerGroup has identified SEER as best in class and has estimated significant growth in the software estimation tool and services market. The products resulting from this SBIR will help Galorath achieve this significant growth.

Title:Software Cost and Schedule Estimating
Abstract:The objective of this Phase 1 proposal is to demonstrate the feasibility of developing a set of software estimation tools and procedures that will estimate software development cost and schedule for software efforts of Naval Aviation. The set of software cost and schedules estimation tools and procedures developed through this project will include Marotz, Inc.'s software estimation tool Cost Xpert. The software estimation models in Cost Xpert will be customized and calibrated to reflect Naval Aviation's specific software development domain and to estimate the costs and schedules of Naval Aviation software development projects with a standard deviation of 10% or less. This set of tools will also include a tool with the ability to update Naval Aviation's project estimates and project baselines to with metrics gathered from by Naval Aviation's automated project management tools. This tool will allow Naval Aviation to record and store actual project metrics, compare actual results with estimated results, when appropriate create new project estimates or baselines, and finally correlate the metrics needed to refine and calibrate the customized Naval Aviation software estimation models.These tools and procedures hold the promise of allowing Naval Aviation to not only effectively plan for the allocation of its resources in the development of new and upgraded systems for the Fleet but also become more dynamic and systematic in its decision making processes throughout the entire lifecycle of its projects increasing the probabilities of project success. Marotz, Inc. anticipates that the same software management professionals that use its estimation tool Cost Xpert will be interested in a tool that ties together general purpose software management tools used by Naval Aviation, the estimation models in Cost Xpert 3.0 and a PERK database. It will be using its established sales channels and relationships with clients to market this tool. Marotz, Inc. estimates that a successful software process simulation tool will be achieve $500 thousand in revenue in its first year after release and $2 million in its second year.

Title:Software Cost and Schedule Estimating
Abstract:The proposal addresses development of a tool to improve software cost and schedule estimating accuracy. After collecting and building a preliminary database of historical software cost, technical, and programmatic data, we will explore application of innovative methods and techniques to use in the software estimating tool. The anticipated results of this research include: 1) an increase in the accuracy of software development and maintenance cost and schedule estimates; 2) a more realistic and defensible quantification of uncertainty (estimating error range); and 3) a reduction in the effort required to generate an estimate and calibrate the estimating tool.Our proposed software cost-estimating tool will be tailored to both the unique requirements of Department of Defense (DOD) organizations and to the unique needs of industry, including defense and other commercial concerns. Because the model will provide a more accurate and defensible cost estimate, we believe we will achieve substantial market penetration within DoD. Consequently, defense firms developing and maintaining software would then have a strong incentive to also purchase and use this model in order to: 1) determine what the government's estimate of their project will be and 2) produce an estimate that the government is more likely to consider reasonable. Because of its proposed built-in capability to tailor itself to the salient attributes of a specific software organization, the model can also be rapidly generalized for use by other commercial firms.

Title:Pressure Sensitive Non-Slip Surface Appliqué for Low Drag
Abstract:Military and commercial aircraft use non-slip treatments on upper areas of the aircraft to provide safe walking surfaces for maintenance personnel and pilots during routine service operations and, in some cases, cockpit access. Current non-slip surface treatments for aircraft rely on fixed surface roughness to provide traction. While these surface treatments provide slip resistance, significant performance penalties in terms of aerodynamic drag can arise due to the surface roughness of these devices. Continuum Dynamics, Inc. (CDI) proposes the development of an innovative Pressure Sensitive Non-slip Surface Appliqué (PSNSA) which is slip resistant when pressure is applied to the surface. Under aircraft flight conditions the PSNSA device has a smooth surface equivalent to aircraft skin yielding low viscous drag and improved aircraft performance relative to current surface treatments. In addition, this non-slip device offers the potential for greater slip resistance in all weather conditions reducing the risk of accidents and injury.The successful development of the proposed PSNSA concept will reduce operating costs for commercial and military aircraft by reducing drag. Additionally this device will make maintenance operations safer by providing better non-slip surfaces on aircraft wings.

Title:Non-skid Coatings for Aircraft
Abstract:Horizontal external surfaces on military and civil aircraft are usually treated with non-slip coatings to provide a safe pathway for maintenance personnel walking on with tools and equipment during service and repair. Current non-slip treatments are heavy and degrade the aerodynamic performance of the airplane because of their high profile. The Department of Navy is looking for a new effective slip resistant surface treatment that does not increase the drag and weight of the aircraft. In this Phase I SBIR project TDA proposes to develop a new anti-slip nanocomposite coating that is light and does not require a high-profile surface roughness to be effective. This new multicomponent material will offer good dry and wet traction and will be applied as a regular topcoat.TDA's material will have immediate application as a coating for the upper surfaces of military and commercial aircraft. Non-skid coatings have other applications including flooring for ramps, aisles, walkways, steps, handicap zones, docking stations, recreational and commercial boats; in forklifts traffic areas, around machinery and in chemical transfer zones. Industries that benefit from the use of anti-slip coatings include chemical plants and transformers, food processing plants, paper mills, hospitals, railroads and subways, wineries, sewage and treatment plants, swimming pools, schools and public facilities.

Title:Fasteners/Rivets for Watertight Integrity and Corrosion Prevention in Permanent Application
Abstract:Military aircraft require corrosion inhibiting sealants around fasteners gaps to prevent fuel leaks, water ingress, and corrosion. Conventional selants must be wet-applied during assembly, which results in excessive labor costs and downtime. Limitations of conventional polyether and polysulfide-based sealants include: the slowness of cure below room temperature, contraction during cure, and cumbersome application methods. A novel fastener sealant based on an expandable matrix resin with microencapsulated curing agents and chrome-free anticorrosive agents is proposed for this application. The sealant is designed to be pre-applied to metallic fasteners, form a thin, dry outer film surface and remain shelf-stable. Upon insertion into a hole, the shearing forces reflow the sealant and activate the base resin curing. The curing process will be accompanied by a controlled level of material expansion for effective sealing. The proposed sealant system should effectively protect aircraft structures from water intrusion and associated corrosion processes. Pre-applied fastener sealants will be formulated with microencapsulated curing agents, low toxicity corrosion inhibitors and rheological additives and tested for adhesion to aluminum and composites, fuel and water barrier properties, resistance to thermal and chemical degradation, and corrosion inhibiting properties. The physical performance will be compared to commercial sealants meeting MIL-S-81733.A pre-applied,chrome-free, expandable sealant having excellent corrosion inhibiting properties would provide the DoD with a cost-effective process for maintaining military aircraft. Potential commercial applications would include the manufacture and repair of civilian aircraft, automotive and marine products.

Title:Fasteners/Rivets for Watertight Integrity and Corrosion Prevention in Permanent Application
Abstract:During aircraft and helicopter production fasteners are currently wet installed with two-component polysulfide-sealant. Applying the two-component sealant is both time consuming and labor intensive. The excess sealant can be classified as hazardous waste. MIL-STD-7179 requires that fasteners be wet installed with sealant to secure water tightness and corrosion prevention. METSS is proposing to apply its expertise in the area of sealants, environmentally friendly corrosion inhibitors, and micro-encapsulation to develop a coating that is applied during the manufacturing process of the fastener /rivet. The dry non-toxic coating developed will provide lubricity during installation, water tightness, and comply with current environmental laws and regulations. Under the proposed program, METSS will evaluate three different approaches to obtaining this objective. These are: (a) low compression set, water repellant, elastomeric coatings; (b) Post fastening, swellable coatings; and (c) post fastening, foamable coatings. Each of these technologies is technically and commercially viable, thereby offering the potential for a near-term solution to this critical problem.The results from this Phase I program will lay the groundwork for a leak-proof, corrosion resistant coating that can be applied on a rivet or other type of fastener used by the U.S. Navy during its manufacturing and will eliminate the need to apply a wet, two-component, polysulfide sealant prior to the rivet or fastener installation. METSS expects that the proposed improvements will very significantly increase the rate of riveting, make it much less labor intensive, reduce worker exposure to hazardous chemicals, and avoid the handling and disposal of hazardous wastes. Successful completion of the research and development work, with participation by one or more potential partners, will facilitate technology transfer and insertion. Subsequent optimization and commercialization efforts by METSS and its development partner(s) will have a significant impact on the specialty fastener sector, which in turn will be able to supply the U.S. Navy, U.S. Marine Corps, and U.S. Coast Guard, as well as the U.S. Army and U.S. Air Force with commercially available corrosion resistant, fastening systems. The technology developed should have additional uses in commercial and industrial markets, for example in the automotive, marine, and building construction industry sectors.

Title:Fasteners/Rivets for Watertight Integrity and Corrosion Prevention in Permanent Application
Abstract:Polysufide sealants work well in rivets/fasteners for Naval aricraft, providing sealing and corrosion prevention functions, but their installation is problematic. The labor and waste hazardous materials associated with mixing the sealant are costly and time consuming. Systems and Materials Research (SMRC) proposes to develop a one-part polysulfide (1K-PS) nanocomposite sealant that activates with the pressure of installation. A nano-putty, containing environmentally friendly anti-corrosion additives, will be formed from COTS 1K-PS liquid by blending in nano-clays and polymeric thickeners. The nano-putty is an uncured state that will be encapsulated to prevent premature cure. The 1K-PS encapsulated nano-putty will be formed into collars and assembled onto the rivet. A full scale demonstration will be conducted at the end of Phase I on a 7075 T6 aircraft aluminum sheet test bed. SMRC has formed a Phase I alliance with a large aircraft fastners company as technical consultant and potential Phase III licensee for self-seal rivets. Southwest Texas State Univeristy, a leader in nanocomposite reserach, will provide subcontract research services, and full access to an 8500 square foot state-of-the- art materials development laboratory. A commericalization plan will be prepared in Phase I that will center on development of a licensing agreement with the Phase I commerical partner rivet manufacturer.The labor and time savings of a self-seal rivet design makes this a very attrractive commerical product. In addition to the cost savings in manufacture and maintenance, the 1K-PS nanocomposite self seal rivet will virtually eliminate hazardous waste volume while improving the reliability of the rivet seal. This improvement comes from standardizing the amount of sealant applied, and the improved sealing function that results from using a nano-clay constituent. Commericalization will be appraoched through licensing the technology to rivet manufacturing companies, with the SMRC Phase I commercial partner as the first licensing target.

Title:Phase I Demonstration of a Passive Missile Environment Monitor
Abstract:The ability to safely detect fuel leaks, salt and water intrusion, charge, shock and temperature extremes in a missile canister is lacking. Normal methods used to determine a fuel leak, moisture, charge, or exposure to extreme temperatures and shock inside a missile canister are inadequate because they require power to operate. The introduction of voltage and current into the volatile fuel vapors, no matter how small, can be catastrophic in that it can ignite the very liquid it is attempting to detect. Battery powered systems are also impractical due to the five year certification period. Mainstream has a developed a concept for a passive inexpensive non-electrical, non-mechanical sensor to perform these detection functions. This indicator does not introduce any electrical discharge when performing the monitoring. Under this Phase I effort, Mainstream will completely demonstrate the leak detector and investigate the ideal configuration for this Navy missile application. The Phase I effort includes an extensive experimental demonstration of a visual indicator for use in missile canisters. Phase I will include critical proof-of-concept experiments to demonstrate the feasibility and accuracy of the proposed monitor. This product would complement our existing line of passive system monitors and our marketing studies have indicated markets for a moisture/temperature/shock version of this monitor for the shipping industry, a charge/moisture/shock/temperature version of this indicator for the computer and electronics industries (for use in shipping and storage), and a fuel leakage indicator configuration for the energy industry.

Title:Low-Cost Missile Environment Monitor
Abstract:The determination of the environmental extremes that a sensitive piece of equipment has been exposed do during shipping and storage is of critical importance. All electronic equipment and chemicals have limitations as far as specific environmental conditions are concerned. If these specific conditions have been exceeded, serious operational problems can result. It is therefore crucial that a sensor that can determine if environmental parameters have been exceeded operates reliably over a long period. To date, most sensors operate with electrical power. This poses serious problems for sensors that need to operate over an extended period of time as batteries deplete and alternative energy sources are required. Midé proposes a sensor array that is purely mechanical and will require no electrical power. This array of sensors will utilize the unique qualities of intelligent materials, specifically smart gels and shape memory alloys to determine if the limitations set for the humidity, temperature, shock, fuel, salt and water levels have been exceeded. This sensor will be built on proven technology and will be extremely cost effective.The smart materials environmental monitor promises substantial returns from the ability to monitor environmental conditions inside commercial shipping containers for sensitive items such as electronics. The monitor offers an inexpensive and easy-to-use solution to check for and ameliorate environmental exceedances.

Title:Low-Cost Missile Environment Monitor utilizing a beam of radio frequency (RF) energy
Abstract:This project will develop a monitoring system for the inside of Tomahawk missile canisters that can operate for an indefinite period exceeding five years with power provided by an external hand held reader using radio frequency (RF) energy. The hand held, battery operated reader will power the transponder inside the missile canister using RF energy to penetrate through its skin, charging a miniature storage capacitor that will operate a micro-power data acquisition system. The sensors will be passive devices only requiring power during readout. Our entire system of transponder and sensors will be easily installed in new or existing canisters without tools because it will be packaged in miniature modules with adhesive backings. All the sailor need do is remove the protective layer on the back of each package and press fit the module to the inside skin of the canister. Phase I will demonstrate the concept in the laboratory with breadboard sensors, the RF link, and a simple breadboard reader. Phase II will engineer an entire system which, in addition to working for Tomahawk missile canisters, will be easily adaptable to a wide variety of commercial applications.System will have wide application in grocery retailing, military logistics, and agriculture, where perishable items must be checked for spoilage without breaking open a package.

Title:Innovative Gas Turbine Engine Propulsion
Abstract:Low Plasticity Burnishing (LPB) has been shown to provide twice the HCF strength of shot peening, and four times the strength after FOD in Ti-6Al-4V and IN718 laboratory specimens exposed to turbine engine temperatures. The deep compressive layer produced by LPB is comparable to laser shock peening (LSP), and can fully arrest the growth of 0.020 in. deep fatigue cracks. LPB offers higher speed, lower cost, and better surface finish than LSP, and is performed on conventional CNC machine tools in a manufacturing or engine overhaul shop environment. The feasibility of applying LPB to compressor blades critical to the NAVAIR IHPTET and VAATE programs to improve damage tolerance and HCF life will be established in Phase I. LPB processing parameters and control software will be developed for following the complex surface of a compressor blade using existing tooling and 4-axis LPB facility. The HCF life and damage tolerance of LPB processed blades will be compared to the current practice of shot peening. Thorough documentation of HCF performance of LPB processed blades and development of an automated production LPB facility for blade rework will be undertaken in Phase II. The anticipated benefit of the proposed effort to NAVAIR is substantial reduction in the total cost of aircraft ownership and improved fleet readiness. LPB blade processing will improve engine HCF life and FOD tolerance, resulting in reduced costs of both replacement parts and maintenance. Increased damage tolerance will reduce required inspection time for further man-hour savings and increased on-wing time. The initial cost savings for the T56-A-427 compressor alone are estimated at $3.6M annually. Current military expenditures of $2B annually to address fatigue of aging aircraft and legacy engines provide the immediate market for LPB and potential savings to the DoD. Commercialization will, therefore, begin with NAVAIR overhaul and then expand to other military aviation applications. LPB is well positioned for commercialization due to low costs of operation and capitalization relative to laser shock peening(LSP), and improved depth and stability of the compressive layer produced by LPB relative to shot peening. LPB can be applied easily during manufacturing operations with conventional CNC tools at engine overhaul centers for much less than new blade costs. Demand for improved HCF performance and cost reduction from military owner-operators will lead to LPB processing of new blades and other critical rotating parts during manufacturing. Military applications will be followed in the commercial aviation sector, driven by improved HCF performance and cost reduction. Potential secondary commercial opportunities for LPB to improve HCF performance in the aerospace, automotive, and power generation turbine industries are vast, and will follow the initial military applications over a period of several years.

Title:Innovative Gas Turbine Engine Propulsion
Abstract:Output shaft torque is a very useful parameter for health and usage monitoring, as well as electronic control, of turboshaft engines. Magnetoelastic polarized band technology is a novel method of torque sensing that provides a wireless signal while maintaining superior torsional stiffness, low mass, and packaging flexibility. Although this technology has been successfully proven in many automotive and industrial applications, its use to date has been limited to average torque measurement and niche production volumes. The objective of this project is to prove the feasibility of a magnetoelastic non-contact torque sensor for turboshaft and turboprop engine applications, with the specific goal of achieving a repeatable signal having large bandwidth from actual measurements on an engine output shaft. This test program is intended to demonstrate enhanced performance as compared with existing torque sensor systems, which more often than not present a heavy compromise among the desired resolution, bandwidth, and packaging. The significant weight and cost reductions, and long-term rotorcraft safety enhancements that can be achieved by the U.S. Navy through this new torquemeter make it well worth evaluating. This initial proveout is intended to provide the basis for a Phase II project to commercialize the technology for various military and commercial gas turbine engine applications.Torque is one of the most fundamental parameters used to analyze and control the performance of rotating machinery. Although all gas turbine engines generate mechanical torque at certain individual stages, turboshaft (and turboprop) engines are particularly well-suited for analysis of their system performance through torque monitoring due to the fact that they provide mechanical power through an output shaft. By demonstrating the feasibility, in hardware, of a magnetoelastic non-contact torque sensor for gas turbine engine output shafts that provides a high bandwidth signal, the following benefits are anticipated:  Far greater flexibility in packaging layout of the engine output shaft assembly  Improved torsional stiffness and output signal resolution with respect to existing strain gauge and phase shift torque sensors  Elimination of compliant torsion bar used in existing phase shift torque sensors, with a consequent weight and cost reduction  Lower torque sensor system and output shaft assembly physical length and mass  Improved ability to detect, and eventually prevent, potentially hazardous engine transient events such as flutter, surge, and stall  Improved HUMS capability during engine operation  Improved controllability of engine torque balancing in dual engine configurations  Enhanced capability for diagnostics in helicopter flight testing programs, especially airframe-engine matching and drive system dynamics The commercial implications of a successful high bandwidth torque sensor development program are significant. Truly non-contact, robust, accurate torque measurement for a variety of vehicle and industrial applications has been an elusive goal for many years. The advent of magnetoelastic polarized band technology, in combination with recent improvements in magnetic field sensor technology, suggest the strong possibility that at last reliable torque measurement, including that of transient events, is a real prospect for machine designers across many fields. Such a development could be put to use successfully in such varied applications as automotive engine control for reduced emissions, power control of helicopter engines and rotors, and tool condition monitoring in CNC machining centers. Due to the fact that there are literally millions if not billions of rotating shafts in the field that could benefit from integrated torque sensing, the ramifications of a successful program for U.S. military and industrial applications are exceptionally broad indeed.

Title:Detection of foreign materials in prepregs
Abstract:Fiber-reinforced polymer prepreg materials are supplied in the form of tape, tow, fabric, etc. During the cutting and lay-up processes, some of the backing material (release film) remains on the material. Composite parts manufactured using such prepreg materials can fail since the backing material prevents a good bond between individual plies. Menon and Associates proposes to demonstrate a magnetic resonance (MR) system to detect the backing material. MR principle is based on exciting the hydrogen atoms inside the material being inspected. Depending on the state of hydrogen we receive a unique signal. For example, the resin used inside the prepreg and the polyethylene or paper backing material have hydrogen atoms. However, the state of the hydrogen atoms in these two are different. We have a hand-held MR probe that can measure relaxation times of the hydrogen atoms in prepreg materials. This will detect any remaining backing material. In addition, if the backing material is aluminum, the MR field gets distorted and this also gives a good response. Using MR (similar to MRI in medical imaging) we can potentially measure wrinkles and voids at different depths by monitoring drastic variations in the signal from the hydrogen atoms from inside the composite. The capability of the proposed MR sensor for early flaw detection will result in a) improved fabrication and thus capability, b) increased life-time of the composite structure, and c) increased cost effectiveness. The commercialization potential is not limited to military uses but also includes civilian applications. Examples are the civilian aerospace industry, the automobile industry and sports industry.

Title:Enhanced Scanning Thermography for Large Scale Composite NDE
Abstract:The increased use of composite materials in the manufacture of structural aircraft components such as the V-22 tiltrotor requires that Nondestructive Evaluation is performed frequently in the early stages of the fabrication process. Although Pulsed Thermography has been demonstrated to be an effective tool for many composite NDE applications, it lacks the speed and low cycle time required for frequent inspection during manufacturing. We have proposed a new approach to composite NDE, Enhanced Scanning Thermography, that provides the advantages offered by pulsed Thermography in a continuous scanning system that is ideal for the large, complex composite structures. The system will inspect parts while they are in the tooling at each debulk cycle, and provide fast, automated identification and measurement of defects such as wrinkles, voids or tape inclusions without operator input or intervention.Our proposal was formulated based on input from current and prospective customers in Government and private aerospace manufacturing, service, and R&D, including NASA, commercial airline, and military NDE personnel. We found that several major aerospace customers (Boeing, GKN Westland, Lockheed-Martin) were still using very crude scanning systems, simply because the systems matched the geometry of the parts they were inspecting. These customers indicated a high degree of interest in a scanning system that would incorporate the advanced features of the pulsed systems that they were using on other applications. Although the proposal has focused primarily on aerospace applications, significant market opportunities exist in the automotive and energy industries. The growing use of composites in automotive manufacturing and is presenting new QA and NDE challenges to the industry. TWI has been a pioneer in applying Pulsed Thermographic solutions to automotive applications, and has worked with Ford, General Motors, Chrysler, Nissan and numerous Tier 1 suppliers. The automotive market is distinctly different than the aerospace market, primarily because of the high volume requirements and the importance of autonomous, on-line systems. TWI has recognized and responded to these needs, will build on our experience in the automotive industry in marketing the scanning system."

Title:Sprayable Polysulfide Elastomeric Development
Abstract:This project will develop a polysulfide based coating system that can be spray applied to marginally sound coatings that are coating steel substrates. The coating will be high solids, preferrably 100% solids, to minimize its environmental impact due to VOCs. The coating will have a low cure stress to aid in the adhesion. The adhesion of the coating system will be such that it will be able to wet out most common coatings already in use by the Navy.The coating will be able to adhere to most coatings used on Navy structures. The cure stress will be very low minimizing the chance of lifting a marginally sound coating system previously installed on the steel. The finalized system will expand our product line to include a process that our customer base is looking for.

Title:High Temperature, High Energy Density Multilayer Power Capacitors
Abstract:At this point in time, existing capacitors technologies fail to meet satisfactorily Navy application needs for parts that are able to deliver energy densities greater than 1 J/cc and that are able to operate in severe conditions such as high temperatures, high operating voltages, and high currents. As a solution to this problem, Sigma proposes to develop a unique multilayer capacitor architecture to produce parts that are projected to deliver energy densities over 10 J/cc. These parts will be rugged enough to withstand the harsh conditions. In the phase I program, we propose to design and fabricate high voltage, high current, high temperature capacitors, with an energy density in the range of 10-20J/cc, based on existing and proven capacitor technology. The new capacitor design will based on Sigma's new nanocomposite patented technology that allows the production of polymer/inorganic multilayer capacitors that have improved self healing characteristics, higher breakdown strength, lower dielectric absorption and superior thermal and mechanical properties which result in higher current carrying ability. In the Phase II program, specific DOD applications will be addressed and capacitors will be produced and delivered for field testingThe new generation high energy density capacitors will serve a multitude of critical high power defense and commercial applications which may include motor controllers, inverters, power conversion, advanced linear motor, implantable defibrillators, pulsed lasers, electromagnetic catapults, high energy switches, radar modulators, isotope separation lasers, directed energy weapons, countermeasure pulse generators and other applications in the power electronics industry

Title:High Dielectric Constant Polymer for Power Electronic Applications
Abstract:Recently it was discovered that a relaxor ferroelectric copolymer consisting of poly(vinylidene flouride - trifluoroethylene) (PVDF-TrFE) exhibits a dielectric constant >60, more than 20 times the values of existing polymer film capacitors. In this SBIR program, TRS Ceramis and its subsidiary Centre Capacitor will demonstrate the feasibility of using this materials for compact, high volumetric efficiency, and low cost capacitors. This technology will bridge the gap between low ESR capacitors made with linear polymer, dielectric ceramics, and ferroelectric ceramics and high capacitance valued components such as electrolytics and ultracapacitors. In Phase I, commercially available polymer film will be processed to determine the optimum irradiation and film annealing conditions. The effect of electrode material (metallization)will also be studied to determine if self-healing electrode technology can be applied to this material. Prototype capacitors will be constructed by lamination techniques and the results will be used for pilot production in Phase II. The overall goal is to meet or exceed the DOD energy density requirement for DC bus capacitors.We anticipate relaxor PVDF-TrFE to be a breakthrough in capacitor technology leading to high volumetric efficiency components applicable to a broad range of markets. Besides military applications, PVDF-TrFE capacitors are expected to find wide use for implantable defibrillators, industrial motor drives, and electric vehicles.

Title:Combined Direct Digital Synthesis, Predistortion and Efficiency Enhancement RI Power Amplifier
Abstract:Broadata Communications, Inc. (BCI) proposes to development a novel Direct Digital Synthesizer (DDS) for high power radio frequency (RF) amplifiers. The development of this DDS is in response to the Navy's requirement for the development of a technique to pre-distort the signal fed to a high power RF amplifier in such a manner as to reduce distortion components to a point lower than -40dBc. This technology will combine digital synthesis and digital pre-distortion with efficiency enhancement to boost RF power amplifier efficiency and, at the same time, reduce cross modulation distortion often associated with higher efficiency power amplifiers. This device will be fabricated using the latest available, off-the-shelf commercial technology. It will be suitable for high power and high efficiency base station applications. Phase I will focus on hardware architecture design and algorithm simulation. In Phase II, a RF power amplifier, driven by the DDS with pre-distortion compensation, will be built to demonstrate the feasibility of the systems.The proposed DDS power amplifier approach is applicable to both, military and commercial markets. High efficiency power amplifier translates into lower battery weight or longer usage and lower costs. Together with low distortion generated by DDS with predistortion for today's highly complex and stringent modulation schemes, the proposed technology is a win-win solution for the wireless communication industry.

Title:Digital Compensation for Distortion
Abstract:The development of a digital signal synthesizer with integrated predistortion linearization (DSS/PDL) is proposed. The DSS/PDL will generate complex waveforms and predistort these waveforms so as to compensate for the distortion of high power amplifiers (HPAs). All signal generation and processing will be done digitally. The use of digital processing for the predistortion (PD) allows precise complex transfer characteristics to be more easily generated. It also allows greater flexibility in generating and modifying these responses. Linearizer Technology, Inc. (LTI) will use its extensive experience in the design and manufacture of linearizers to develop a new class of digital distortion equalizers that offer superior performance, are faster and more efficient than earlier designs, and that are commercially viable. A novel architecture will be employed to overcome stability problems and allow a wider dynamic bandwidth than previously possible. Linearizers are essential in systems carrying bandwidth efficient modulated (BEM), high data rate digital signals. The largest part of LTI's business is providing linearizers to manufacturers of HPAs for satellite earth stations. Linearization is also of great value to the wireless telephone and personal communication industry. The implementation of digital techniques will allow LTI to produce linearizers with greater performance at a lower cost.LTI specializes in the solution of problems involving all aspects of non-linearity in communications systems. Although LTI provides both manufacturing and consulting services, LTI's principal business is the production of linearizers for microwave power amplifiers. LTI now makes more than ten standard linearizer models covering the L,S,C,X,Ku,K and Ka bands, designed specifically for satellite ground station and terrestrial applications. In addition, LTI offers custom linearizer design services for frequencies from base-band through millimeter wave and above, and engineering consultation for all forms of distortion related problems. LTI Linearizers are in use in the US and throughout the world. Users include SSPA, TWTA and KPA manufacturers, satellite system operators, major teleports and satellite users. These customers have continually expressed a desire for linearizers that will provide increased linearity, greater operational bandwidth and do not require alignment. These are the features offered by the DSS/DPL to be developed by this proposal. The digital predistortion technology will be initially integrated into the design of our standard linearizer products and offered as an option. This option will be promoted in the same way other LTI products have successfully been promoted. A new line of high performance linearizers tailored to the cellular and personal communications market place will be developed. This market place has not been directly addressed by LTI because of the difficulties involved in producing linearizers with very high C/I performance. The development of multi-band linearizers will also be considered. Interest has been expressed in a single linearizer to cover the C,X and Ku-bands for tri-band TWTAs. Such multi-band performance has not been possible with a single PD generator, but with a digital PD it should be achievable. Other business opportunities are anticipated as word spreads of the capabilities of digital PD linearizers.

Title:High-Resolution Digital Linearity Distortion Compensator
Abstract:This Small Business Innovation Research Phase I project demonstrates a breakthrough approach to high-resolution linearity error compensation (LinComp) using computationally-efficient digital signal processing to reduce harmonic and intermodulation distortion in digital-to-analog converters (DACs), analog-to-digital converters (ADCs), sampling circuitry, and radio frequency amplifiers (or the combination of these devices in the complete RF chain) by at least 24 dB. This technology improves the dynamic range by at least four bits, enabling very accurate synthesis of data at high intermediate frequencies (IF) with very high sample rates (e.g., 18-bit dynamic range with 300 MHz sample rate or 12-bit dynamic range at GHz sample rates). The LinComp technology reduces the size, power, and cost of radar systems and RF transceivers by eliminating much of the RF electronics and reducing the digital signal processing requirements. The significant performance improvements afforded by this approach over traditional compensation techniques will be demonstrated in Phase I by implementing the digital processing in realtime FPGA hardware, demonstrating efficient auto-calibration routines, an testing the processor on a combination of devices in an RF chain. The auto-calibration routines will be built in FPGA hardware in the Phase I Option. V-Corp has confirmed the technical efficacy of the LinComp processing methodology by testing with state-of-the-art digital-to-analog and analog-to-digital converters. This compensation approach requires less hardware, provides much better dynamic range, and provides compensation over a wider bandwidth than competing linearity compensation methods (such as phase-plane compensation and dither). Very importantly, the LinComp processor will always exceed the state-of-the-art because it can easily be upgraded as new, more powerful DAC, ADC, and amplifier products become available. During Phase II, a compact LinComp DAC prototype will be developed with a high-speed waveform generator and RF electronics to enable high IF direct digital synthesis (DDS).The LinComp approach overcomes the critical D/A conversion bottleneck which limits performance of state-of-the-art radio frequency transceiver systems. Virtually any high-performance modern electronic system will benefit from the LinComp DAC. Significant applications include enhancement of radar systems, wideband universal RF transceivers, specialized test equipment, and medical imaging systems.

Title:Simulating Data for the Development of Decision-Making Systems
Abstract:Sensor outputs form the foundation for decision support systems. Accurate models and simulations of these sensor outputs enables effective development, test, evaluation and use of decision support systems. Phase I focuses on chemical/biological detectors because their variability embodies cutting-edge problems in the field of sensors and detectors. Phase I will focus upon the requirements, specifications, design, and methodology for modeling and simulating the inputs to decision support systems from outputs of detection (sensor) systems, which transform input data sources and associated uncertainties. These uncertainties include meteorological fluctuations, intrinsic and extrinsic noise of detection system channels and components, computer precision errors, and external disturbances. Existing simulations will be evaluated for incorporation into the methodology. Phase I will develop an initial prototype simulation of decision support system inputs, based on the methodology and simplified sensor models and simulations for the emerging Navy Artemis and ion mobility spectrometer detection systems. The resulting methodology will be extensible to other sensors. Phase I option period will add a graphical user interface prototype, initial database, and perform verification and validation. Phase II will develop a fully functional software prototype, including support for synchronized time representations between simulations.The sensor simulation environment will have applications as a simulation environment used by sensor/instrument manufacturers, government program managers, chemical process industries, and the developers of decision support systems.

Abstract:Dynamics Technology, Inc. (DTI) will develop non-acoustic ASW (NAASW) sensor algorithms and software to provide simulated sensor data, measures of performance, and innovative displays to support the analysis and development of decision aids for submarine situation awareness/vulnerability and mission planning. The approach is based on adapting and extending the Navy-standard PC-FOM suite of NAASW sensor performance models, which encompasses a wide range of sensors/signatures, and leverages two decades of Navy R&D and validation against high-fidelity simulations and field data. PC-FOM sensor models are designed to run rapidly and to provide militarily useful measures of performance such as probability of detection, making it ideally suited to decision aids. In addition to sensor performance modeling, DTI will develop candidate processing algorithms and displays (e.g. vulnerability maps, route planners) for integration into existing or future mission planning tools. Phase I research will: 1) demonstrate the utility of existing PC-FOM models and identify/prioritize upgrades and additions, (2) define NAASW decision aid CONOPS and display concepts, (3) demonstrate sample algorithms for vulnerability displays, and (4) determine the detailed requirements for Phase II development of a prototype NAASW sensor model and decision aid. The proposed effort supports a current need for vulnerability assessment and mission planning tools to support submarine operations in littoral environments. There are identified user needs and transition to operational use by Special Forces (NAVSPECWARCOM), ONI (threat assessment), ASW forces (e.g. vs. foreign air-independent propulsion subs), and the Submarine Technology Program (N775).

Title:Innovative Sensor Technologies for In-Situ Air and Ocean Sampling under Extreme Conditions
Abstract:The objective of this proposal is to demonstrate the feasibility of measuring in-situ the parameters necessary for the calculation of heat and momentum flux at the air-sea interface under very calm to moderate sea conditions. The Micro-Buoy proposed here will provide an off the shelf solution for the measurement of the near surface fluxes at a cost low enough to permit multiple synoptic deployment. Multiple buoy deployments will enable a better understanding of the local variability on time and space scales of order of seconds and meters to days and kilometers. The Micro-Buoy is fitted with the eddy correlation heat and mass flux instrumentation. With this package the heat and momentum flux is found at both sides of the air-sea interface. Measurements within a distance less than the significant wave height are difficult due to imperfect coupling to the sea surface of the measurement platform. The Micro-Buoy will allow accurate, high-resolution measurement of temperature and velocity micro-structure to within fractions of a meter of the water surface. Once the Micro-Buoy technology is developed, custom sensor packages will also be possible in addition to a standard set of sensor packages through the implementation of a modular design strategy.The expected market for the Micro-Buoys is the scientific community including various governmental agencies, academic institutions and the offshore oil industry. All of these parties have an interest in low-cost accurate assessment of the ocean environment and the air-sea surface fluxes of heat and momentum.

Title:Compact High-Power Electronic Components
Abstract:This Phase I SBIR proposed the development of technology that will lead to smaller, lighter and more efficient power amplifiers for driving the highly reactive loads presented by active sonar transducers. Compared to other amplifier components, existing designs employ physically large, high weight magnetic components in the amplifier-transducer coupling interface. Proposed research will focus on two new and innovative circuit topologies that accomplish the required transducer image impedance transformation by novel means. The approaches have the potential to realize substantial amplifier size and weight reduction while maintaining high overall efficiency when driven by state-of-art Class D power modules. The final part of the investigation will consider a fusion of the two approaches that may have advantage, especially for low frequency applications where magnetic components greatly increase size and weight of the amplifier. Phase I option will involve the design and fabrication of prototype power amplifier circuitry to test the analysis developed in Phase I and verify the operation of each circuit approach.The proposed research provides an important means of reducing overall weight and size in power amplifiers used in active sonar systems. Results will apply to the immediate market for the space/weight/efficiency optimized power amplifiers aboard Navy surface, submarine and airborne ASW platforms; and autonomous acoustic source systems such for acoustic tomography, active Navy sonobuoys, acoustic countermeasures, LELFAS and ADLFP. Other applications for the resulting technology will be in spacecraft and aircraft systems, where the benefits of space/weight efficient products are obvious. Additional applications include power distribution and power amplifier systems, control actuator driver circuits and high power modulators for communications

Abstract:This Phase-I SBIR program will investigate novel techniques for the efficient delivery of signal power to reactive loads such as are required in sonar systems. Class-D and class-S power amplifiers with very fast switching offer a theoretical efficiency of 100 percent. Maintaining high efficiency with a reactive load is achieved by very fast switching, achieved by a new type of complementary MOSFET. Bandwidth can be extended by a new minimum-rating filter that allows maximum bandwidth within a given set of power-amplifier voltage and current ratings. An electronically tuned output filter allows significant extension of the frequency range. Electronically tuned inductors and semiconductor capacitors currently under development for another application can be adapted for such filters. Commercial applications include not only sonar and high-power audio amplifiers, but also RF power systems including RF heating, antenna tuning, jamming, and magnetic-resonance imaging.

The digital controller will be able to download accurate phasing information directly into the drive electronics at high-speeds essential to the integrity of the waveforms. This modular system remote programmable towed array technology will function at full operational efficiency with an inverter module failure and enables `at convenience' low-cost replacement.Immediate applications include the enabling the use of high efficiency power electronics for the controls and audio systems industries.

Title:Silicon Carbide Technology for a Hull Mounted Sonar System
Abstract:The development of compact, light-weight power-electronics for driving underwater acoustic transducers has been the subject of research over the past 30 or more years. Improvements have occurred in parallel with advances in power electronic switching devices, most notably, the development of the silicon MOSFET, essential for the high-efficiency switching-amplifier technology widely used today. We are on the threshold of another advance in power-electronics, the advent of silicon-carbide semiconductor technology, which offers great improvement in semiconductor operating temperature and voltage ranges. Its higher temperature capability will enable greater packaging density and its higher voltage capability will provide a closer matching of the switching device voltage rating with the voltage requirements of typical transducers, leading to the possibility of size reduction in impedance matching components. We propose to research the application of silicon carbide technology to an example hull-mounted sonar system, the AN/SQS-53C (part of SQQ-89 system), and determine its beneficial impact on transducer, power-amplifier and overall system design.As a minimum, we expect an improvement in power-amplifier density due to the higher temperature capability of silicon carbide, a benefit particularly significant for pulsed-power applications such as the 53C, with its high peak-to-average power ratio. A major benefit is the possibility of eliminating the power-amplifier output transformer. This transformer weighs an estimated 3 pounds and occupies about one-third of the volume of the power amplifier. For a system of about 600 amplifiers, the weight savings would be on the order of 1800 pounds. We expect the high voltage, high frequency capability of silicon-carbide switching devices will be adequate for driving the transducer element directly, eliminating the need for the output transformer. If the transformer can be eliminated, a third benefit is the possibility of integrating the power amplifier with the transducer, offering the opportunity for another significant reduction in overall system size and weight.

Title:A Low-Cost Airborne EO Oceanographic Measurement System
Abstract:The goal of this SBIR proposal is to evaluate the feasibility of transferring technology developed by Arete Associates for a UAV surrogate payload, the Airborne Remote Optical Spotlight System (AROSS), to a system capable of being mounted on an aerial photography airplane. AROSS is a field-tested and robust electro-optical system producing time-series imagery with sufficient resolution and spatial coverage for Navy METOC requirements. The approximate cost of $2000 per hour to fly AROSS, while not expensive by military standards, restricts its non-warfare or commercial use and its participation in ongoing scientific research. The development of a system similar to AROSS, which can utilize commercial aircraft, would cost less to build and reduce operating cost by a factor of 5 to 10. The limitation of the new system will be a restriction in the viewing geometry resulting from using a downward looking viewport instead of a military-based turret. Arete proposes to assess the effects of the restricted viewing geometry, using AROSS data, and determine the engineering requirements to mount such a system on standard, commercial aircraft.The successful transfer of AROSS technology to a system capable of being mounted in a commercial aircraft will be an inexpensive oceanographic research asset. This asset will directly benefit the Navy wave modeling community who require wide-area measurements of METOC parameters, including directional wave spectra, in the littoral zone. The lower operating cost of the proposed system will be more in-line with the budgets of typical field experiments designed to enhance scientific understanding of coastal processes. Government agencies responsible for coastal waterways, such as USACE, and mapping, such as NIMA, represent potential customers who can utilize the low-cost rapid bathymetric and current survey capability of the proposed system.

Title:Miniature Infrared Transmissometer (MIT)
Abstract:The goal of this Phase I effort is to find a practical optical and physical instrumentation geometry that will result in a miniature infrared transmissometer (MIT) capable of estimating in-situ and in real time the atmospheric extinction coefficient for aerosols with particles ranging in size from a fraction of a micron to tens of microns. The approach of this research is to investigate the wavelength scaling between light scattered by the particles in the visible spectrum and the aerosol infrared extinction coefficient in the two atmospheric windows as a function of potential MIT geometries. Such scaling was previously described in the literature, but has not yielded a practical and miniature atmospheric sensor for estimating infrared extinction. Innovative solutions for known problems with the wavelength-scaling method will be sought to make the MIT a practical wavelength-scaling instrument.There presently exists no practical method for real-time and in-situ measurements infrared aerosol transmission (extinction). An atmosheric sensor such as the MIT would benefit the operation of infrard optical systems.

Title:Optimization of an Ionospheric Imaging Instrument for Geosynchronous Orbit
Abstract:Disturbances in the earth's ionosphere can affect systems that rely on trans-ionospheric RF propagation. Validated DoD needs for real-time monitoring of ionospheric weather are not being met by current remote sensing techniques. Our proposal supports development of an ionospheric imaging instrument capable of providing realtime information on a global basis about ionospheric irregularities to improve tactical operational responses supporting surveillance, navigation, communication, missile defense, and precision geolocation. This SBIR effort focuses on reducing the instrument's cost, mass, and volume to facilitate integration as a secondary payload on geosynchronous satellite platforms. Future deployments aboard these platforms will enable real-time global monitoring of ionospheric disturbances affecting both DoD and Civil Sector systems.A successful effort would lead to production of multiple ionospheric imaging instruments as part of a global multi-platform geosynchronous real-time imaging system for monitoring structures and tracking irregularities within the earth's ionosphere. The system would provide real-time information to systems affected by ionospheric disturbances leading to improved surveillance, navigation, communication, missile defense, and precision geolocation. Potential applications to private industry communication systems may also provide benefits.

Title:Weather Radar Processor for Rapid Scanning Tactical Radars
Abstract:This Phase I SBIR proposal describes a weather radar processor that will be used to add a weather surveillance mode to existing military radar systems. Existing tactical radars, such as the TPQ-37 and MPQ-64, are highly sensitive search and track radars whose basic operational parameters are ideally suited for weather surveillance applications. During Phase I, we plan to work with engineers from the radar manufacturer to design one or more weather surveillance modes for the TPQ-37 and MPQ-64. A custom radar signal processor will be designed to extract reflectivity and Doppler data from the analog output of the radars. This data will be merged with antenna scanning, time stamp and geo-location information to accurately display the output data in world coordinates. Recurring and non-recurring costs to modify the radars for weather surveillance applications will be determined. The pulse-to-pulse scanning agility of these radars makes them especially powerful tools for the study of rapidly developing convective weather systems that are poorly characterized by conventional PPI-scanning weather radars.Commercial applications include modification of existing and new TPQ-37 and MPQ-64 radars for tactical and civilian weather surveillance applications. The radar processor developed through this SBIR can be readily modified for use with other civilian weather radars.

Title:Four-Dimensional (4-D) Atmospheric and Oceanographic Instrumentation: A Novel Dual Wavelength Optical Beam Attenuation Meter for Automated Underwater
Abstract:The technical and commercial feasibility of developing a miniature dual wavelength optical beam attenuation meter for use with Automated Underwater Vehicle (AUV) systems such as the REMUS is evaluated. The meter will use a novel Scattering over Dual-Pathlengths (SDP) approach, where two measurements of light backscattering are made with identical angular weighting functions but over different pathlengths. Using a single source, beam attenuation is readily derived from the ratio of scattered fluxes measured by the detectors and the difference between the two pathlengths. A key issue to address in determining feasibility is the tradeoff between increasing resolution and decreasing signal return as a result of increasing pathlength differentials between the two scattering measurements. A second challenge will be determining how to minimize and account for any light that is scattered more than the single incident in the sample volume (intersection of detector field of view and source beam), but still makes it to the detector. The SDP approach is likely the key to solving the apparent paradox of making high resolution attenuation measurements over very long pathlengths with a compact sensor. The sensor will be low power, robust, and have the approximate dimensions and volume of a hockey puck.Beam attenuation is a key property in diver visibility and vulnerability models, lidar performance models, and in determining particle concentrations in natural waters. Currently there is no commercially available miniature sensor for measuring optical beam attenuation with high accuracy. Such sensors are needed for deployment on the new generation of sampling platforms such as AUVs, profiling/gliding floats (e.g., the ALACE floats), and long-term, unattended observing systems. In the near future, thousands of such sampling platforms will be built. Revenues for a compact, high accuracy attenuation sensor costing about $3000 per unit are expected to be about $1.5 million annually (500 units per year).

Title:Data Link System for In-Situ Ocean Observing Platforms
Abstract:According to a report by the National Oceanographic Partnership Program (NOPP), knowledge of the ocean is demanded by many constituencies including climatologists, fishermen and fisheries managers, harbor pilots, coastal zone managers, Navy and Coast Guard commanders, Public Health Service officers, environmental protection professionals, commercial and recreational boat and ship operators, weather forecasters, and the offshore mining and oil industry. Many of these needs are being met by in-situ ocean observing platforms such as drifting surface buoys, moored buoys, floats, remotely operated vehicles and ships, just to name a few. For these platforms, the NOPP has placed a high priority on the development of technologies that disseminate data in a timely manner. A variety of commercially available low-Earth orbit (LEO) satellite systems produced by the private sectors are now in, or will soon achieve, operational status. They have the potential to meet NOPP's requirements including two-way communications, real-time data transmission, global coverage, high data rate and reduced costs. As a result, NAL Research proposes to design and build a data link system utilizing LEO satellites to collect environmental parameters from ocean observing platforms and to deliver them to users worldwide in real-time.Satellite data link system can be extremely useful in many applications. Ships, airplanes and trucks have relied on geostationary satellites to provide mobile satellite services for years. Now, LEO satellite data link system will soon make mobile satellite services available for individuals. Any type of transmission, internet connection, voice, fax, data or paging, will soon be able to reach its destination anywhere on the planet. The system will simplify communications for business professionals such as salespeople, field producers and reporters for television networks, construction engineers sending plan revisions, oil-company geologists uploading test results, just to name a few. People who live in thinly populated areas that will never be covered by regular cellular phone service, travelers, private pilots, yachtsmen and disaster relief teams will benefit from the LEO satellite-based data link system as well.

Title:A System for the delivery of data from remote unattended platforms using a Low Earth Orbit Satellite (LEOS) system
Abstract:Field observational programs coordinated under the Ocean.US program require a reliable, global coverage, cost-effective, and flexible method of returning data from remote platforms, including moorings, surface drifters, and ALACE and PALACE floats. The present methods of doing this have many disadvantages: high costs, excessive latency, limited bandwidth, and limited geographic coverage. The PI proposes an integrated system for the retrieval and delivery of data from remote-moored and drifting unmanned sites and platforms in the ocean, using the Iridium Low Earth Orbiting Satellite (LEOS) system as the data carrier. The project will be coordinated with the Ocean.US Office and Ocean.US participants. The system will include a remote data communications package, bulk purchases and management of Iridium airtime, a data download hub with an Internet gateway, two-way comm- unications capability, and itemized billing. In Phase I, the PI will work in close collaboration with the NOPP Ocean.US Office to develop a detailed design, determine the cost-effectiveness of the proposed system and compare it with existing and planned next generation systems. We will prepare a risk and cost-benefit analysis comparison. We will also survey the market, both within the US oceanographic community and beyond.The anticipated benefits to the ocean research and operational communities are the availability of a system for the retrieval of remote data from ocean platforms which: = Provides true global geographic coverage = Uses a small, lightweight, low-power remote unit = Includes platform location capability = Provides higher base bandwidth (10 kbits/sec) than currently-available systems = Allows for channel multiplexing to achieve higher effective bandwidths = Has a lower cost per kilobyte of data traffic than any currently-available system = Can transmit data in real-time = Allows two-way communications = Provides a central system for support, itemized billing, and carrier quality monitoring = Provides a mechanism for automatic real-time distribution of data via the Internet = Provides a web-based data management and display service The system will be cost effective for delivery of data from terrestrial sites as well as ocean platforms. It has many potential commercial applications, including data communications for: = Ocean drilling platforms = River monitoring stations = Vessels at sea and in port (e-mail and data) = Geologic (earthquake) monitoring sites = Hazardous waste monitoring sites = Railroad infrastructure monitors = High-value mobile cargo monitoring = ...and others The proposed system would have advantages over the systems presently used for these applications: = Low cost per kbyte = Higher bandwidth = A single protocol/procedure globally = Lower cost equipment = Global coverage = Real-time data delivery = Allows two-way communications = Central itemized billing for multiple sites

Title:Technology for Shipbuilding Affordability
Abstract:The objective of the project is to demonstrate that practical, affordable, and reusable software components can be used to create an affordable, real-time production monitoring and control system for U.S. shipyards. Atlantec and National Steel and Shipbuildng will develop, test, and demonstrate two product prototypes: "Production Monitor" an application that integrates engineering, production, with planning and scheduling; and "Shop Floor Client," a computer work station located in production areas. "Shop Floor Client" will allow production workers to retrieve and edit on-line production information from an on-site computer. Production processes will also be visualized in a "geographical" view of shipyard facilities, showing an activity at the production location providing the actual work status by work resource. The Proposed products, "Production Monitor" and "Shop Floor Control" will support just-in-time practices, enhancing productivity and reducing costs in U.S. Shiyards. Interim product, product model information, production status, and work order information will be accessable anywhere at anytime in the enterprise. The products will enable shipyards to integrate concurrent operations with real-time production information. The products will be affordable, practical, and will be easy to use and implement.

Title:Automated Planning and Design for Producability and Maintainability
Abstract:Ship construction represents one of the more challenging planning problems in industry today. The purpose of this proposal is to reduce ship construction and operation costs by making optimal use of available automated fabrication facilities and designing for maintainability. An efficient algorithm for solving this class of problem has been discovered. The feasibility of developing software tools for automatic assembly planning and detailing of ship structure and outfitting and automatic maintenance removal planning will be demonstrated, using this algorithm. The tools would automatically plan assemblies, determine joint locations in piping and seam locations in structure, layout piping in banks, and plan maintenance access. A working prototype will be developed to verify that acceptable levels of fidelity and performance can be achieved. These new innovative tools will use accurate models of shipbuilding fabrication processes and life cycle operations so that they generate optimal designs/plans for shop production. In addition to the construction cost and life cycle maintenance savings, use of these tools will enable a substantial reduction in planning man-hours. The intent is to develop software components to be integrated into existing commercial CAD/CAM and planning systems. New design and planning business practices using these tools will be outlined.Anticipated savings are $160 million per year in construction costs and $1 million per year in planning costs for U.S. shipyards and $16 million per year in reduced ship maintenance costs for ship owners. This assumes that 10% of piping fabrication work is moved from in-dock and in-module on-site fabrication to mechanized shop fabrication as a result of this project and that 5% of structural fabrication operations are moved from on-site fabrication to mechanized process lanes as a result of this project. A 5% reduction in ship maintenance costs is assumed through optimum design for maintenance.

Title:Material Identification and Procurement System (MIDAPS)
Abstract:We propose to design, build, and deploy a Material Identification and Procurement System (MIDAPS). MIDAPS facilitates information-integrated synchronization of construction activities with materials management functions through a rapidly reconfigurable, centralized relational database management system. MIDAPS facilitates both new construction and ship repair jobs. The Phase I effort will define, design, and build a prototype MIDAPS. The Phase II effort will rapidly transition the innovation into an operational shipyard application. The most significant innovation of the MIDAPS concept is the development of a materials system that becomes a real time management decision tool rather than a quasi-static information statusing tool. MIDAPS benefits include (a) significant reductions in ship construction and repair cycle time and cost, and (b) substantial gains in ship throughput and capacity. The proposed open-architecture, model-based approach will produce accelerated and affordable deployment of the technology to the U.S. shipbuilding community.MIDAPS applications areas include Enterprise Resource Planning, Material Requirements Planning, Finite Capacity Scheduling, Material Planning and Control, and Production Planning and Control.

Title:Technology for Shipbuilding Affordability
Abstract:A well-designed integration of a machine's control system with a CBM system will reduce manufacturing costs, simplify maintenance, reduce risk of critical failures, and reduce life-cycle cost of the machinery. This Phase I proposal's goal is to demonstrate the commercial and technical merit and feasibility of a combined CBM and control system for diesel generator sets on the Caterpillar 3608 and 3616. This machinery is not now digitally controlled, nor is it equipped with a CBM system. Both generators are either currently in service or scheduled for service soon aboard Navy ships, and each will eventually feature an electronic fuel control system. Choosing to integrate the engine control and CBM systems before designing either system will significantly reduce design, development, and implementation costs of both compared to designing and building both systems separately and then integrating after the fact. For example, the two systems can share a substantial portion of the sensors and other elements that typically compose the separate systems, thus reducing the total number of parts required and systems costs. The work accomplished by successfully integrating the engine control and CBM systems will benefit these generator sets and other machinery throughout the Navy and in commercial applications. Note attached letter of support from Caterpillar.The benefits anticipated from this project fall into three categories: 1) The direct and near term benefits derived from cost savings in acquisition and maintenance of the 3600 series gen-sets. Savings result from avoiding the cost of separate CBM and control systems and from the reduced cost of maintenance compared with a periodic preventative philosophy of run-to-failure. 2) Lessons learned and system design accomplished on this project will translate readily to other ship machinery, both new and legacy, generating savings as described above. 3) Because of the R&D accomplished in the project has direct and immediate application outside the DoD, rapid commercialization is anticipated in 3600 series gen-sets, and on a wide array of other machines. Note attached letter of support from Caterpillar.

Title:Cellular Wireless Sensor System for Aircraft Health Management
Abstract:Modern wireless systems such as cellular are practical due to the integration of radio, processing, and semiconductor technologies, and as production volumes have grown, component prices have dropped. Reduced costs and well-developed design methods may now combine to provide software controlled and highly cost effective wireless monitoring. The development and production costs for this equipment are easily offset by reduced maintenance cost and staffing allowed to users of the system. For military aircraft maintenance applications equally important issues are improvements in mission effectiveness and capability that result from reduced down time, higher reliability and sortie generation rates, and improved safety. Use of the commercial Industrial, Scientific, and Medical bands for this system design allow commercial reuse, and thus provides lower cost and greater availability to military users. The system will be designed with a Time Division Multiple Access (TDMA) Automatic Repeat reQuest (ARQ) for high spectral efficiency and reliability. The MicroRadio and data acquisition technology base of Cleveland Medical Devices provides an ideal starting point for this program.Greater military aircraft mission effectiveness, crew safety, and simplified maintenance are the chief benefits of this program to the military. However, the methods developed here will be immediately applicable to civilian aircraft maintenance, particularly airliners and corporate aircraft, and also to myriad other civilian monitoring applications. Virtually any complex equipment for which expensive regular maintenance is required could benefit from this new technology. Health monitoring of humans and animals may prove to be an even larger market than industrial and military data acquisition.

Title:Wireless Sensors Systems for On-Board Aircraft Health Monitoring
Abstract:Aircraft diagnostic and prognostic systems can enhance aircraft safety, reduce total costs of ownership, and increase asset availability. However, they require a great deal of integration with the platform. Wiring such a system into the aircraft makes up a large percentage of overall system complexity, cost, and weight. Wireless transducers have enormous potential to simplify new and retrofitted diagnostic/prognostic systems by eliminating currently required cabling and interconnects, enhancing robustness via redundancy, easing sensor placement, and reducing system weights. A wireless system also allows for flexibility in sensor placement to meet changing system needs and to aid in identifying, troubleshooting, and monitoring emerging fleet problems. Luna Innovations and its research partners will develop a wireless sensor system for on-board, real-time aircraft health monitoring. The development team will survey the aircraft application and determine candidate sensors and system architecture. The system will work under constraints such as long operational lifetime, low power, non-light-of-sight, high bandwidth and ease of integration. The developed system will consider flight qualification, sensor size, and will offer performance comparable to existing systems. Luna will leverage previous wireless sensor development efforts and commercial production capabilities to satisfy the immediate Navy requirements and bring the developed technology to near-term market. Luna Innovations anticipates large related markets in preventive maintenance systems and diagnostic instrumentation coupled with wireless transmission capability. Specific applications include shipboard, spacecraft, aircraft, and nuclear/conventional power plant health monitoring, transportation vehicle design and testing, and industrial rotating machine monitoring. The previous success in this area resulted in a spin-off company, dedicated to the production of wireless instrumentation systems for industrial rotating machine health monitoring utilizing off-the-shelf RF technology, and has over $1 million/year in revenue. Products resulting from this research will undergo immediate transition for introduction to the market.

Title:Integrated Simulation-Based Design Environment
Abstract:This proposal provides a solution to problems in using disparate integrated computer-based design tools to determine the performance of underwater weapon and vehicle concepts. The proposed system would consist of a suite of domain-specific engineering software applications that undersea weapon and vehicle engineers would access and operate via personal computers as thin-clients over a secure network. Critical to enabling this design environment is a middle layer of software that provides workflow management, messaging services, analysis integration, optimization, and data and model persistence. A presentation layer of software applications will be able to provide an immersive user interface to interactwith engineering applications. Such a system can be easily extended as new analysis applications become available and as the user community grows. The benefit of such a system has two components, reduction of total ownership cost, and improved quality of design. The reduction of cost comes from the fact that potential design conflicts have been resolved early in design, in such a way that optimizes not only the weapon or vehicle design, but also its manufacturability, and life cycle maintenance costs. The system acheives this benefit by encouraging product team members to utilize the best available design, manufacturing, and operation tools, as well as to communicate and negotiate frequently. The system benefits not only the design team, but also the application developers, by allowing easier updates of codes during the design cycle, and by providing an environment to test, validate, and benchmark new codes. To the undersea weapon and vehicle design community, the system provides a framework for the product development, access to all the necessary applications, and produces greater capability than the individual applications alone.

Title:Integrated Simulation-Based Design Environment
Abstract:With the increasing complexity and size of advanced system designs come increasing requirements for an integrated set of methods and tools to measure, evaluate and predict behavior and performance. An environment is needed that will allow the engineer to rapidly iterate through multiple design paths and options, while evaluating the capability and completeness at multiple levels of abstraction. An integrated distributed environment is needed for engineers that support their processes and tools. This environment must support design, visualization and analysis at varying levels of detail. These capabilities can only be realized through the incorporation of a framework consisting of an integrated set of tools sharing a central design data repository that has "plug-in" support for external tools and codes. Creation of a robust environment to support complex systems development includes several key elements: first, an extensible framework and for integrating tools for designing, simulating and visualizing various aspects of the design; second, a process for using the tools and integrating and sharing their data; and third, a formal schema for describing, capturing and interrelating the data used by the tools. This project will attempt to realize a prototype of such an environment for the design and optimization of undersea weapons and vehicles. Successful completion of this project will represent a significant advancement in the design and optimization of undersea weapons and vehicles decreasing the design time while improving the performance and overall quality of the systems produced. This environment will provide an open, ubiquitous, distributed environment that will not only integrate existing and future codes and tools but also provide configuration management, asynchronous integration, advanced analytical and visual capabilities, as well as a flexible scalable environment based on Trident's Interchange product.

Abstract:Chemical kinetics based solid propellant combustion predictive capabilities have developed to the point where it is possible to compute combustion properties of solid propellants. Specifically burning rates over a range of pressures and temperatures. This capability will reduce the time, effort, and cost in developing solid propellants for a variety of combustion devices from rockets to air bags.The ability to predict solid propellant combustion properties will reduce cost and effort in designing and formulating new propellants. The cost savings to industry and the government are potentially enormous since only likely propellant formulations will be progress to the mix, cure, and testing phase of the development cycle.

Title:Prediction of Hyperbaric Oxygen Seizures Using Neural Networks
Abstract:It is known that hyperbaric oxygen (HBO) exposure causes seizures in animals and humans, although the mechanism by which this occurs is still incompletely understood. Oxygen toxicity is a concern, for example, in certain types of military diving operations, as well in treating patients in clinical HBO chambers. At present, the most reliable physiological "marker" known to anticipate HBO-induced seizures is escape from cerebral vasoconstriction. To provide an "early warning" system for increased probability of HBO-induced seizures practicable for field and clinical use, non-invasive measurement parameters are needed. For example, hyperbaric hyperoxia is known to increase the parasympathetic influence in the regulation of the heart. Therefore, subtle changes that occur in cardiovascular parameters (e.g., heart-rate variability) prior to the onset of seizures may be exploitable markers. Barron Associates, Inc. will apply its neural network estimation and classification technology, in conjunction with various signal analysis and nonlinear dynamics pre-processing techniques, to identify predictive cardiovascular parameters and to relate such parameters to seizure onset time and/or the probability of seizure occurrence. Successful development of a methodology that can account for individual differences in HBO susceptibility will lead to improved safety in diving and clinical applications. The proposed neural network-based predictive modeling technology has strong potential for application/integration in the Lung Automatic Regenerator (LAR) V Oxygen Breathing Device used by Special Operations Forces breathing pure oxygen. HBO therapy is widely used for the medical treatment of decompression sickness (i.e., the "bends") and many severe medical conditions (e.g., chronic wounds, acute blood loss, anemia, carbon monoxide poisoning, tissue/bone damage from radiation, gangrene, smoke inhalation, crush injuries, decompression sickness, air or gas embolism, persistent fungal infections, cyanide poisoning, bone infection, skin flaps/grafts with poor blood supply, and cerebral palsy). Improved prediction of HBO toxicity will have a large impact in HBO treatment.

Title:Prediction of Hyperbaric Oxygen Toxicity
Abstract:Military divers and medical patients undergoing hyperbaric oxygen (HBO) therapy may breathe pure oxygen. The elevated ambient pressure levels in these circumstances lead to high partial pressures of oxygen which can become toxic. The goal of this program is development of a Diver Warning System capable of monitoring environmental and physiological parameters and predicting impending seizures due to oxygen toxicity. During Phase I, we will review existing data and literature, implement several novel data processing algorithms, and determine which parameters are most predictive of impending seizures. During Phases II and III, the work will be extended to include additional hyperbaric testing and integration of the Diver Warning System into the LAR V Rebreather used by military divers.Successful completion of this project will increase the safety of military divers exposed to hyperbaric oxygen. The technology developed under this program may also benefit recreational scuba divers and medical patients undergoing hyperbaric oxygen therapy.

Title:Needleless Topical Administration of Dengue DNA Vaccine
Abstract:Dengue virus (DV) is a serious threat to people including military personal in endemic areas. So far no prophylactic vaccine is available. The aim of this study is to develop a DV vaccine patch. Transcutaneous vaccination by topical application of a patch requires a lower level of medical training, is economical, painless, safe, and effective in a number of animal models. The hypothesis is that the expression of pre-membrane and envelope proteins (preM/E) in the outer layer of the skin following inoculation of DNA vaccines can stimulate neutralizing antibodies against preM/E and thereby induce a protective immune response against DV infection. Cholera toxin has been used as adjuvant for transcutaneous vaccination. We have previously shown that an immune response can be elicited by topical application of a plasmid coupled to adenovirus and that GM-CSF can enhance the potency of transcutaneous vaccines. In these studies, we will evaluate cholera toxin as well as GM-CSF as potential adjuvant for a DNA-based transcutaneous vaccine against DV. We will also compare the protocols developed in this proposal to their counterparts using intramuscular injected DNA vaccines. The line of investigation proposed herein may allow the development of efficacious and safe vaccination protocols against DV infection.The transcutaneous DNA-based vaccine as proposed in these studies could arrive as the first prophylactic vaccine against dengue virus infection if its efficacy and safety should appear superior to other methods. People living in endemic areas, military personal deployed to the tropics and subtropics and travelers would greatly benefit from an effective dengue vaccine, particularly a dengue vaccine patch that can be administered simply and confers no pain.

Title:Autonomous Solid Phase Microextraction for Explosives Detection and Identification
Abstract:The overall goal of this project will be to develop an automated sampling and chemical analysis system that can be used for detecting trace concentration of explosives in marine environments. Such an analysis system can be integrated into a small autonomous underwater vehicle (AUV) and employed for the identification and mapping of unexploded ordnance in bodies of water. Phase I will involve the design and fabrication of a prototype pre-concentration sampling instrument based on solid-phase microextraction (SPME). The prototype sampling instrument will automate the steps involved in the SPME sampling (extraction and desorption) and will be designed so that it can be easily interfaced with existing analytical methods for detecting explosives. The proposed design will utilize miniaturized components to achieve a compact, rugged sampling system that can be easily integrated in AUVs.The development of an autonomous underwater sampling and chemical analysis system for explosives will be both beneficial to the military and commercial sectors. An underwater explosive analysis system will be particularly advantageous to the Navy because it will provide an advance warning to naval vessels of the presence of mines in the surrounding area. This is important because it will then allow naval personnel to perform appropriate countermeasure actions. In the commercial sector, the underwater explosive system will also be important for environmental monitoring applications as well as in law enforcement.

Title:Novel Sample Collection Method for Locating Seamines
Abstract:Nomadics proposes to design and evaluate a fast, in-situ apparatus to sample nitroaromatic explosives in marine waters. The sampler will extract explosive compounds from plumes around seamines and unexploded ordnance (UXO). By following a plume to its source, an autonomous underwater vehicle, guided by the sensor, will be able to locate seamines and UXO. The design introduces two novel technologies to allow rapid detection of trace signature chemicals of seamines. The system uses an innovative method for rapid mass transport of analyte into the sampling chamber. The second innovation is the sensor platform, which uses Nomadics' proven Amplifying Fluorescent Polymer sensor. The sensor has been demonstrated to detect extremely low concentrations of vapor-phase TNT and recent studies substantiate its ability to detect TNT in a water matrix. During the Phase I effort, Nomadics will demonstrate the ability of the collection system to present detectable levels of analyte to the sensor. During the Phase I Option, Nomadics will focus on enhancements to the system to support the transition into full prototyping in Phase II and then commercialization.The proposed system provides a way of locating explosives underwater that can be applied to detecting seamines, locating submerged UXO, finding lost ordnance, etc. These applications can be used by defense units and search and recovery organizations. The novel sample collection system is complementary to a number of sensor technologies, including ion mass spectroscopy, and the sensor platform can be functionalized to detect other substances. Therefore, the proposed technological innovations can be applied to a large number of chemical sampling and analysis scenarios.

Title:A COMPACT SUBMERSIBLE TRACE CHEMICAL ANALYZER FOR TRACKING PLUMES OF CHEMICAL EXPLOSIVES WITH AUTONOMOUS UNDERWATER VEHICLES
Abstract:A small autonomous underwater vehicle (AUV), with appropriate chemical, acoustic and optical sensor systems, would be a useful tool for remote, automated tracking and mapping of underwater plumes of leaking organic chemical explosives and locating their source. Presently it is not possible to survey and track such underwater plumes because available AUV-deployable chemical analyzers do not have the required lower limits of detection and fast response times. The primary goal of this Phase I project is to demonstrate the feasibility of developing an autonomous Submersible Solvent Extraction Module (SubSEM) that utilizes integrated microfluidic circuits to continuously sample and preconcentrate (100X - 1000X) explosive organic chemicals (i.e. TNT, DNT) that may be present at ultra-trace concentration levels in marine waters. The design of the miniature sized SubSEM will enable coupling to comparatively sized submersible chemical detection systems. The resulting compact submersible chemical analyzer will be readily integrated into small AUVs. The envisioned submersible chemical analyzer would also have the analytical selectivity, sensitivity (sub part-per-trillion) and fast response times (seconds) that are required for underway tracking of plumes of chemical explosives and the detection and identification of unexploded ordnance in the marine environment. AUVs with integrated high-resolution chemical and physical sensor systems are clearly needed for rapid detection, classification and localization of mine-like objects and unexploded ordnance in shallow water operating environments. Similarly designed AUVs could also have substantial private-sector applications in marine waters including, environmental investigations of the hydrodynamics of riverine and sewage inputs, hypoxia, harmful algal blooms and chemical pollution events, and commercial aviation search and find missions. There are also numerous private sector applications for submersible chemical analyzers with the lower detection limits afforded by the envisioned SubSEM preconcentration module. Examples include environmental monitoring of industrial and municipal waste streams for compliance and in-line quality assurance monitoring in chemical and pharmaceutical processing plants.

Title:Underwater Sampling Inlet/Preconcentrator System for In Situ Chemical Measurements of UXO Contaminants in Seawater from AUVs
Abstract:Thorleaf Research proposes to develop and and test a rugged underwater sampling inlet/preconcentrator (SIP) system for in situ chemical analysis of seawater samples from a small autonomous underwater vehicle (AUV). This addresses a key technology gap for in situ underwater sampling and preconcentration of such analytes, mainly how to acquire and pre-process trace level analytes from seawater while remaining within challenging mass, volume and power constraints. Although various miniature chemical detectors are under development for explosives, their potential for the identification of UXO in marine environments will not be realized without complementary developments in technology for underwater collection and pre-processing of samples. The proposed SIP system will be suitable for coupling to such detectors, isolating them from the pressure of seawater at the selected sampling depth, and providing for automated 100-1000x preconcentration of TNT and other UXO analytes. The goal of our proposed SBIR Phase I effort is to demonstrate feasibility for a miniaturized, low power sampling inlet/preconcentrator system for in situ chemical measurements of UXO contaminants in seawater from AUVs, to develop detailed designs for fabricating prototype instrumentation in Phase II, and to fabricate and test a SIP system breadboard in a Phase I Option.By following an inherently modular design approach in developing this sampling technology, it is anticipated that modifications will allow it to be adapted to meet needs for a variety of underwater chemical measurements. This is likely to include terrestrial uses, such as environmental monitoring of water quality and monitoring for hazardous materials. Our proposed SBIR effort to develop a miniaturized, low power, underwater sampling inlet/preconcentrator (SIP) system for in situ chemical analysis addresses these needs in an innovative way, and thus technical developments in the proposed program could have a significant commercial market impact.

Title:Device Independent Voice-To-Voice Language Translation Software
Abstract:The proposed innovative development and demonstration of a pocketable voice-to-voice language translator is achievable because it uses LSI's current PC-based, speaker-independent, two-way voice-to-voice translation software as a foundation for the effort. The development will involve six technical tasks; the first four are planned for the initial Phase I effort, and the last two for a Phase I Option. Tasks 1 and 2 involve extension and enhancement of LSI's current voice translation software using VoiceXML and Java to provide platform independence and a capability for remote activation. Task 3 is dedicated to dialog development/extension for a selected military application, and 4 is a test of the software developed under Tasks 1-3. Task 5 is a proof of concept demonstration for the standalone capability, and 6 involves experimentation with cellular, PDA, and hybrid devices to determine the optimal platform for both local standalone and remote capabilities. Motorola, which has expressed interest in the project, can assist LSI in testing the remote translation software, and in evaluating platforms for local and remote capability. The commercialization strategy for this development will follow LSI's strategy for commercializing our current voice-to-voice translation software, originally ported to the PC environment under a previous DARPA/Air Force effort.The pocketable voice-to-voice translator will benefit LSI's current law enforcement clients, as well as medical and paramedic service providers, retail financial service providers (banks, loan companies, real estate companies, insurance companies), organizations with multinational operations, business travelers and tourists.

Title:UV/Blue III-Nitride Micro-Cavity Photonic Devices
Abstract:The research proposed here is built on the recent successful fabrication of the first electrically-pumped III-nitride micro-size LED, micro-size LED arrays, and waveguides by the principal investigator's research group at Kansas State University. New physical phenomena and properties begin to dominate as the device size scale approaches the wavelength of the light they emit, transmit, and detect. In this realm, quantum nature of light dominates, enabling more efficient and fast devices. The micro-size lasers and LEDs allow the ability to create arrays of individually controllable pixels on a single chip. Potentially these micro-size light emitters can operate as large arrays or independently to communicate millions of messages (or images) at the same time. Such vast numbers of micro-lasers could be used to read, write or process two-dimensional images, and to speed the flow of information between memory and processing chips as well as between different computer boards. Micro-cavity lasers based on III-nitrides offer additional benefits including shorter emission wavelengths (higher optical storage density and resolution), the ability to operate at much higher voltages and power levels due to their mechanical hardness and larger band gaps, and high speed due to the intrinsically rapid radiative recombination rates. The objectives of this Phase I research are to further develop the III-nitride micro-cavity photonic device technologies and to demonstrate the feasibility for achieving electrical pumped microcavity lasers as well as the integration of miniaturized light emitters with waveguides.III-nitride microdisk and microring lasers and arrays developed here are not only useful in compact displays, but also useful as emitters for remote free space functions and in short distance optical communication and high resolution and high speed optical links. By combining millions of the laser beams of these micro-lasers together, one may also obtain extremely high power lasers with very small size and simple designing. When an array of III-nitride microcavities is reverse biased, it can be modified as a miniaturized UV detector array. Thus III-nitride microcavity photonic devices open many important applications such as optical communications, signal and image processing, optical interconnects, computing, enhanced energy conversion and storage, chemical- and biohazard substances and weapon detection and warning and medical. III-nitride LED technologies will pave the way for full color displays and mixing three primary colors to obtain white LEDs for general lighting. The P.I.s have already developed a novel LED architecture that utilizes microdisk cavity LEDs and can boast the emission efficiency by more than 60%. Finding methods for increasing LED efficiencies is a key step for many applications, including full color displays and general lighting. There is an enormous market interest in the area of general lighting based on LEDs.

Abstract:We propose to develop and commercialize GaN-based blue and near UV light integrated optoelectronics technology for modulation, switching, and distribution of blue and near-UV light. This technology will include integrated optical waveguides, splitters, and electrooptical modulators integrated with LEDs and photodetectors. We will investigate waveguiding in thin GaN, AlN, AlGaN, and AlGaInN films grown by SET, Inc. on different substrates. We will evaluate light coupling using commercial LEDs and blue high-brightness LEDs fabricated by SET, Inc. We will explore the integration design of GaN and GaN/AlGaN photodetectors developed by SET, Inc. The initial modulator work will investigate and implement an acousto-optical modulator based on GaN technology. The technology evaluation will rely on modeling and simulation using our optoelectronic CAD tool - simulator called photonic AIM-SpiceBiological and chemical substance detection and identification is very important for medical, biological applications, as well as for chemical and automotive industry. Integrated blue optoelectronics sensors have promise for the development of cheap and reliable GaN-based sensor systems drastically reducing cost, improving reliability, and safety.

Title:Sonar Stimulation for Virtual Targets in Netted, Tactical ASW Training on Legacy Submarines
Abstract:The Battle Force Tactical Training (BFTT) Program is the most widely recognized Navy program for in port netted training. The operational fleet desires to achieve a Netted ASW Training capability for the submarine community during range operations. Through use of current underwater communication modem technologies, the submarine would be able to communicate in net-centric training situations thus creating a synthetic battlefield situation. Progeny Systems has technologies that allow us to propose innovative bandwidth utilization, data compression techniques, as well as other weapon simulator systems to support the development of a complete "virtual" battlefield operation. Our communication management and data compression techniques have been successfully demonstrated at CTF-12 during the Advanced Undersea Warfare Concept (AUSWC) system demonstration in August 2000. Our data compression techniques were specifically designed to provide battle group connectivity for the submarine using legacy 2400-baud communication links. Through the adaptation of these data compression, data prioritization and data extraction algorithms to the underwater communication modem technology, we will enable the submarine to participate in BFTT operations. By evaluating Internet-Gaming technologies, we propose to further enhance the submarines ability to participate in this limited connectivity environment thus providing a reliable, efficient connectivity Advanced Training Capability.Progeny Systems is in the unique role of defining and constructing the battle group connectivity infrastructure required to link the ASW systems from surface, sub, air, surveillance and shore-based systems for the AUSWC system. As such, the concept of acoustic modem one-way connectivity for the submarine could be used in non-secure operations during battle group operations. We believe by coupling BFTT ASW Training Goals with the operational ASW Battle Force Connectivity a military commercialization opportunity with ASN RD&A may be available to demonstrate additional objectives in Battle Force Connectivity.The results of this project also have application to both commercial and military systems. Initially, this product would be best applied to government agencies and DoD for fleet submarines. As such, initial customers are intended to be PMS401, PMS415, PMS425, PMS450 programs and NAVSEA 92L1. Since the research is targeted towards improving coordinated (via netted communications) ASW training, the resulting technologies from this topic could support training in complex-theater operations, net-centric war gaming, airborne surveillance, NAVAIR, and surveillance applications requiring multiple participant training operations. Potential commercial applications are bandwidth management tools for enhanced Internet gaming, training for coordinated search and rescue missions and ocean exploration. During the research cycle, we will be in constant contact with industry, military, and university experts in the related fields. This will also provide us with the opportunity to identify new methods for achieving high performance innovative communication applications using industry standard development environments.

Title:Fiber Optic System to Measure the Size Distribution and Concentration of Airborne Aerosols in Multiple Locations of a Sampling Inlet.
Abstract:This proposal discusses the development of an aerosol size spectrometer based on an innovative fiber optic system that provides versatility and ruggedness. The system will be compact and flexible and will provide the capability of installing multiple optical probes in an airborne sampling inlet or duct. The fiber optic system will be capable of measuring the size distribution and concentration of airborne particles using well-established principles that are similar to those used by the externally mounted probes. Analytical and experimental studies will be conducted during Phase I to demonstrate the feasibility of measuring the required size range of 0.5 to 50 Šm and to work in flows with velocities from 1 to 100 m/s.The particle sizing system proposed here would be of significant benefit to government and industry engaged in atmospheric particle sizing and pollution monitoring. Instruments presently produced by several manufacturers would derive great benefit from the compactness and multi-probe capability of the proposed system. In addition to the airborne application, potential users include industries and Government agencies interested in powder technology such as food, pulverized coal combustion, and sand blasting.

Title:Characterization of Aerosol Inlets and Ducts
Abstract:Atmospheric aerosols have a strong potential impact on both global radiative forcing and the planetary hydrological cycle. Quantitative measurements of the particle size distribution and composition of aerosols are required to reliably predict the influence aerosols are having on global climate change. Quantitative assessment of aerosol composition (i.e., chemistry) currently requires that air be ingested in the cabin of a research aircraft, where losses in the inlets and tubing are unavoidable. Simple and reliable instrumentation is needed for quantifying particle losses in inlets and tubing. In Phase I, we will design, build and make laboratory tests of a prototype instrumentation system for reliably measuring particle size distribution in tubing just prior to entry into cabin instrumentation. The inlet/tubing characterization system will easily be transferable from station to station and will be totally compatible with measurements made by the FSSP-300 and FSSP-100, currently the most reliable instrument for measuring aerosol size distribution outside the aircraft. In Phase II we will build an airborne version of the new instrumentation system and make comparative measurements with an FSSP-300 mounted on the outside of a research aircraft. It is expected that the new device will eventually be low-cost and readily adaptable for application in all inlet/tubing systems and research aircraft. Aerosol measurements are becoming increasingly more important and it is expected that inlet calibration devices will be purchased by almost all of the groups using research aircraft. In addition to research aircraft, inlet calibration devices will be useful in ground based operations, including measurements of pollutants in urban atmospheres and effluents from stacks. The ground-based applications open an extremely large commercial market.

Title:A Knowledge-Based Indications and Warning Toolkit for Mixed-Initiative Information Warfare Analysis
Abstract:Naval intelligence centers validate, correlate, and analyze information from various sources (cryptologic sensors, tactical airborne reconnaissance, units in contact with the enemy, etc.) to generate Indications and Warning (I&W) in support of friendly operations. Increasingly, naval intelligence centers are deployed in littoral regions around the world. The close proximity of littoral threats significantly decreases warning and reaction time for friendly forces, while anticipated reductions in shipboard manning and increases in the range and quantity of available sensor data further exacerbate workload for intelligence personnel. New information fusion technology is required to help intelligence analysts meet these challenges. Accordingly, we offer a mixed-initiative knowledge-based approach to multi-source intelligence analysis in which user-specified rules and scripts are employed to infer I&W from large volumes of sensor data. To ensure scalability, the proposed system operates in three stages: data transformation, trend identification, and script/plan recognition. Data transformation performs statistical analyses and generates potentially useful abstractions of sensor data. Trend identification monitors these abstractions for user-specified triggering events. Finally, the script/plan recognition step generates I&W by matching these triggers to user-specified scripts for operationally significant activities. The technology developed under this program will immediately benefit cryptanalysts at naval intelligence centers, but also has ready application to intrusion detection for defensive IW, and to multi-source intelligence analysis for DoD and law enforcement.

Title:Indications and Warning (I&W) Inference Engine for the Information Warfare (IW) Picture
Abstract:There are many approaches to improving IW systems' ability to provide Indications and Warning (I&W) for the Information Warfare (IW) Picture. Traditional approaches have relied on rule based systems to infer the RF environment. But in the modern IW battlespace the rules may change too quickly to effectively write IW heuristics. This SBIR takes an innovative approach to deriving the IW Picture by investigating self-organizing algorithms to quickly classify and parse the RF environment in a high-order parametric space only available to the sensor itself. A number of algorithms have been tentatively identified as prospective candidates for investigation, including hard and soft Hebbian learning and neural-gas algorithms. It is expected that these algorithms have the potential to separate signals not only by their individual parameters (frequency, bandwidth, etc.), but also by important (and a priori unknown) joint parameters such as transmission timing, secondary signal follow on, and diffuse RF environmental changes. During Phase I, the self-organizing algorithms will be selected and put into a mathematical foundation suitable for inferencing using IW system high-order data sets. The algorithms will be coded (JAVA is the current language of choice for machine independence) and subjected to well controlled data sets with parameter vectors that match IW systems used in both the National and Tactical RF environment. The performance of the self-organizing algorithms will be evaluated and compared. It is anticipated that one or more algorithms will be recommended for further testing in a prototype system. Initially this software system will be demonstrated on the new generation of IW systems, such as those built on LIGHTHOUSE Technology. However, by using JAVA as machine independent code, the software can migrate to other generations of IW equipment. It is expected during Phase II that a successful IW Inferencing Engine will become a GCCS-M/CUB software segment. We envision multiple opportunities for commercializing the software products that are developed under this SBIR. The immediate opportunities for commercialization involve other government agencies that have similar problems with rapidly interpreting changes in the RF environment, whether to identify hostile threat or to recognize illicit communications. There are extensive applications in the telecommunication industry for monitoring and predicting traffic loads and managing predictable interference. Further, the same concepts of self-organization may be applied to other disciplines including weather prediction and stock-market forecasting.

Title:Enhanced Data Rate Performance for VLF/LF
Abstract:Fleet Submarine Broadcast System (FSBS) VLF/LF communications are severely bandwidth limited due to the high Q of the transmit antennas and the low frequency of the VLF/LF band. The existing communications modes were designed using Minimum Shift Key (MSK) waveform modulation built into analog modulation and demodulation equipment. Soon the very capable digital Submarine Low Frequency/Very Low Frequency VMEbus Receiver (SLVR) will be deployed throughout the submarine fleet, and the analog modulators will be replaced by digital modulators. Advanced modulation techniques such as partial response continuous phase modulation (CPM) at higher baud rates can now be considered for implementation in FSBS communications equipment. In addition, Low Density Parity Check Codes (LDPCC) that provide additional coverage performance through forward error correction (FEC) are already being used for FSBS communications and additional improvements in these codes have been identified. Finally, incremental improvements in current Range Extension Mode (REM) message data compression are also feasible. TSC proposes to investigate designs that incorporate a combination of advanced modulation techniques, adaptive data compression, and larger block size and higher code rate LDPCC for the band-limited VLF communication channel in order to increase the data rate of FSBS information transfer 2 to 5 times yet maintain good coverage range.This research will establish the compatibility and combined performance of partial response continuous phase modulation (CPM) used with Low Density Parity Check (LDPC) forward error correction codes and will establish the compatibility and combined performance of these with adaptive message data compression techniques. These results will lead the way for SPAWAR to incorporate these improvements as software modernization/upgrades into Navy VLF/LF transmit and receive terminals. In addition, these results may also be implemented in application-specific integrated circuits (ASICs) or software modules as data rate upgrades to HF, VHF or UHF narrowband communications modes.

Title:Remote Data Set Manipulation and Fusion via Bandwidth-Independent Networks
Abstract:The approached described within this proposal focuses on the identification and analysis of existing data sources and their targeted users, coupled with the development of a prototype client-server network and user application. The results from the data sources and user analysis will provide us with valuable data to be used for testing purposes during Phase I. Also, the information will give us a jump-start in developing the complete system during Phase II. The prototype network and application resulting from Phase I will demonstrate the capabilities of the client-server network. Results will demonstrate the ability for remote users, regardless of bandwidth limitations, to access, view, fuse, and manipulate data from multiple sources. Emphasis will be placed on the layout of the network, the necessary hardware, the development of a user application, and techniques to limit the amount of data that actually needs to be physically moved. A detailed description of how the network will be laid out will be presented, along with how the software will be developed to bring together the entire network.Anticipated benefits include order of magnitude improvement in data management capabilities of remote users restricted by low bandwidth communications channels. Commercial opportunities exist in providing access to data at locations, especially third-world countries, where the data communications infrastructure is rudimentary or non-existent and low-bandwidth satellite communications is the only option.

Title:Optical Powering Of Systems
Abstract:Undersea, fiber optic, cable systems are currently either battery powered or powered from shore via a conductor that is part of the cable. For the former, large battery packs must be deployed wherever electronics are located along the system. For the latter, the conductor in the cable dominates system size and controls system cost. An alternative concept is to power the fiber optic cable system by sending laser power from the shore side of the cable that is tapped off at locations where electronics are located and converted to electrical power for powering the electronics. In Phase I Aculight will extend a breakthrough technology it has developed on DOD funding to demonstrate diffraction limited diode laser bar sources that can be coupled efficiently into single mode fibers at the multi Watt level. In addition, Aculight brings new manufacturing techniques, based on semiconductor fabrication, that will result in robust and long life power sources. This combination will provide an efficient and compact device for supplying optical power into a single mode fiber for optical-to-electrical converters. Our proposed Phase I work will demonstrate the feasibility of achieving the Navy specifications in laboratory experiments. This ambitious plan is possible because of closely related research accomplishments.Techniques that deliver optical power into a single mode fiber, or multi-mode fiber, have significant markets in DOD (illuminators, power into fibers, pumps for fiber lasers) and the commercial sector (telecommunications, marking, materials processing, sources for end pumping solid-state lasers, and medical diagnostics).

Title:Compressed Internet Protocol (IP) Data Via Geosynchronous Earth Orbit (GEO) Satellite Circuits
Abstract:TCP/IP is the leading protocol used by networked applications the Navy requires to perform its mission. However, TCP/IP was designed for use in reliable, but possibly congested, wired networks, and thus does not support stealthy communication over intermittent and degraded wireless links as required by the submarine fleet. To enable IP-based applications in the submarine environment, CTI will investigate and define requirements for an integrated system, comprising enhanced Data Link and Transport layers, and an innovative Application Traffic Controller, that provide optimal SATCOM link utilization despite high/unstable Bit Error Rate, low bandwidth, long latency, and intermittent connection. For use under Low Probability of Detection / Intercept conditions, additional protocol enhancements will provide reliable transport of IP traffic to the submarine without acknowledgement. This system will operate over any intermittent and degraded wireless media such as HF, UHF LOS/SATCOM, and sonar data transmission, providing significant benefit to both Commercial mobile platforms and Naval mobile assets such as surface ships, aircraft, brown-water Navy, and special operation forces. The severely constrained radio communication environment of a submarine coming infrequently to periscope depth, with a small antenna rising barely above the waves from a rolling platform, confounded by anti-jam and LPI requirements, is a worst case for mobile wireless networking. Historically, the commercial wireless industry has not focussed on such harsh environments. Now, however, network operators and equipment manufacturers recognize a large and growing demand for reliable provision of multimedia services to highly mobile users with extremely small devices, despite severe multipath, fading, interference, spectrum crowding, etc. Solutions to this Navy problem should be directly cross-applicable to the consumer space.

Title:Runtime Evaluation and Prediction System (REPS)
Abstract:OTI proposes to research and develop the Runtime Evaluation and Prediction System (REPS) technologies providing the advanced methodology, techniques and integrated tool suite required for the most effective utilization of existing simulation capabilities for real-time or near-real time course-of-action (COA) analysis. In rapidly changing environments, maximum benefit from simulation technologies can be achieved only if the simulation users can reliably predict the time delay from the beginning of a simulation-based analysis effort until the results become available. In addition, REPS capabilities will greatly improve the potential benefit from simulation through significant improvement of productivity from the available resources, including both computing resources and human analyst resources. Significant productivity enhancements are expected from REPS as a consequence of better allocation of the limited human and machine resources to focus on those simulation scenarios that are likely to produce the required analysis results within the specified time constraints.As both DoD and commercial systems continually grow in size and complexity, simulation techniques are increasingly used to evaluate expected system behavior under a wide range of possible conditions. However, increasing size and complexity of the modeled systems also tends to rapidly increase the runtimes for the simulations and the application of simulations for course-of-action (COA) analysis requires that the simulation-based analysis results be available in time to impact the decision making process. Furthermore, it is frequently the case that the selection of simulation configuration parameters can have a very large impact on the runtime of a simulation experiment. REPS provides the additional automated tool support is necessary to reliably and accurately predict the runtime of a simulation model based on the configuration of models, model parameters, and the availability of simulation execution host machines. REPS research will greatly improve the ability to quickly and accurately predict the runtime for simulations employed for the purpose of course-of-action (COA) analysis. Specific benefits from improved predictive abilities include: 1) greater effectiveness of existing simulation based course-of-action (COA) analysis techniques; 2) more efficient utilization of scares human resources; 3) more efficient utilization of limited computing resources; 4) reduced frequency of analysis results that are not produced in time to be useful for decision making processes.

Title:Precise Time and Frequency for Navy Applications
Abstract:As the reliance on the Global Positioning System (GPS) increases, so too does the risk to dependant systems caused by GPS signal outages or acquisition problems. Timing and synchronization systems, such as Navy operational sites, can benefit from a precision common time reference that offers atomic frequency standard stabilities without drift or total dependency on GPS receivers. Advanced atomic clock technology utilizing Coherent Population Trapping (CPT) as a basis can provide a compact, cost effective solution to the growing need to provide a coordinated knowledge of time while maintaining independence from the GPS system. NAVSSI and Link-16 terminals could be significantly upgraded upon the availability of reliable atomic clock performance in a package compatible with subject Navy hardware.The CPT clock technology has a wide range of applications outside of the military frequency and time area. A compact, low-power, low cost frequency/time standard would find a market in virtually every aspect of modern electronics including communications, test and measurement, computer networking and personal location and positioning devices.

Title:PICO - A Small, Intermediate-Term Precision Time and Frequency Source for NAVSSI and LINK-16 Terminals
Abstract:Syntonics proposes to develop a precision time and frequency source with excellent intermediate-term timing stability (accuracy better than 1e-12 seconds over several hours), long life and high reliability. This intermediate-term precision time and frequency source will use a time scale generator based on an ensemble of small quartz oscillators. This product would give the Navy an inexpensive time and frequency standard with the precision necessary for the Navigation System Sensor Interface (NAVSSI) and Link-16 terminal, but with significantly higher reliability and longer service life that any solution using an atomic physics package.An inexpensive, highly reliable and long-lived time source with the signal purity and short-term (i.e., up to approximately 20 minutes) stability of a good quartz oscillator, and with the intermediate-term (i.e., 20 minutes to one day) stability of an atomic standard would have numerous commercial applications. Today's marketplace offers a variety of cesium- or rubidium-based frequency sources with good intermediate- and long-term time stability, but their short-term stability and phase noise performance is inferior to a precision quartz oscillator. Further, they are relatively expensive, unreliable and short-lived compared to quartz oscillators.

Title:Information Warfare Sensor and Wireless Network Using TM-UWB
Abstract:We propose to develop an information warfare sensor network based on Time-Modulated Ultra-Wideband radio. TM-UWB radio has several characteristics which make it ideal for low cost covert recovery of wideband data. The only signals transmitted by UWB radio are pulses generated pseudo-randomly in time. The Fourier transform of a perfect impulse is constant at all frequencies. The pulses we are currently using are ź nanosecond in duration and the energy extends approximately from .5 to 4 gigahertz. The energy content in any conventional frequency band is far below the noise, making TM-UWB transmission very difficult to detect unless you know the specific pseudo-random sequence of the pulses. With TM-UWB there is no carrier frequency, there is no up conversion and no down conversion required, and the output stage is a single transistor which creates a binary pulse, all resulting in decreased radio size and complexity. The duty cycle of the pulses is approximately 1/500, resulting in low power consumption because 99.8% of the time, nothing is being transmitted. During phase I we will demonstrate UWB communication at 5 miles with at least two simultaneous channels. We will also evaluate several innovative system concepts related to the IW sensor network, including ad hoc network protocol and range measurement capability.While IW sensors do not represent a very large commercial market, the basic technology has very large commercial potential in health, telecommunication, manufacturing, and security industries. For example, in the health care industry, TM-UWB offers a single mechanism for wireless communication to and from mobile instruments, plus it offers the ability to track the position of each of those mobile assets.

Title:Information-Technology-Enhanced Asymmetric Sensor Star (ITEASS) Wireless Network for Recovery of Wide-Band Data
Abstract:Physical Optics Corporation (POC) proposes to design and develop an entirely new wireless network for recovery of wide-band sensor data. This network is based on the Information Technology-Enhanced Asymmetric Sensor Star (ITEASS) architecture, which consists of an asymmetric communication interface (CI) for both longer-distance (100 mile) BLOS (beyond-line-of-sight) communication between a relay and processing center and short-distance (5 mile) sensor wireless LAN (WLAN) with LPI and LPD. The proposed network has exceptionally high tolerance to multipath errors, necessary for sensors fielded in urban and littoral areas. System novelties include: low millisecond latency, essential to real-time interaction sensor control; PCMCIA sensor-specific communication interface; IT-superhigh compression encoding for wide-band sensor data; and spread-spectrum-code-division-multiplexing access (SSCDMA) software and hardware. The ITEASS will be modular to accommodate diverse sensors (TV, video, wide-band RF, radar imaging, sonar, acoustic, seismic, and EO/IR imagery). It will operate at 50 MHz for BLOS: TCDL, CDL, IDL; and ~1 GHz for the sensor LAN. The stand-alone system will cost only ~$100 per board, in spite of its supercomputer-class 8BOPS distributed processing power. It will be compact (2 in. x 3 in. PCB); low-power (~1 W); mass-producible; and designed for both required modes of operation: snap shots and streaming.Commercial applications include the rapidly growing world markets for cellular videophones (2.5G and 3G), video conferencing, IP-streaming video, and video surveillance, which together are expected to generate annual sales of $250 billion in the year 2002.

Title:A Multisensor Approach to Covert Acoustic Calibration of Littoral Environments Using Sources of Opportunity
Abstract:Submarine detection in the littoral environment is a very challenging problem. Acoustic propagation depends critically on complex oceanography and bottom sediment type. The difficulty lies in determining these quantities in a covert manner. We propose the development of a suite of algorithms that will fuse multiple platform data received from surface ships of opportunity to determine the environmental parameters required for ASW operations. The objective of this work is the development and evaluation of four algorithms (with increasing complexity and pay-off). The algorithms range from critical angle estimation from striation patterns to matched field geoacoustic inversions using simulated annealing. Each algorithm will be developed and evaluated using existing data. One available data set is from the ADS Fleet Exercise Test/SwellEx-99 conducted in 1999. This includes GPS records of ship tracks, environmental measurements for "truth" estimation, and data from ADS and several other acoustic arrays. The objective of Phase I is to validate the scientific approach to environmental characterization and to select appropriate algorithms for further development. In Phase II, a system concept will be developed for insertion into select ASW assets. Phase III will conclude with sea trials and system installation into one or more of the specified IUSS systems.Phase I of this research will lead to robust algorithms that determine the physical quantities of interest to current ASW platforms (beamformers, prediction models, noise models, etc.). These algorithms will be used to produce an automated rapid environmental calibration software suite for the ARCI-IUSS acoustic processing system. We envision this being used daily on a submarine in forward areas where geoacoustic/oceanographic sound speed databases are sparse, or for the ADS system where covert calibration is required. Given accurate geoacoustic parameters for an area and real-time surface ship locations, a real-time ambient noise model can be used to determine tactically relevant system performance.

Title:Effectiveness of Doubler Plates as a Permanent Repair Under Cyclic Loads in a Highly Corrosive Environment
Abstract:The feasibility of the use of doubler plates as a permanent repair under cyclic loads in a highly corrosive environment will be demonstrated during the proposed Phase I effort. The work plan will include a review of literature, review of use of doubler plates, investigation of corrosion issues, investigation of crack initiation and growth, and investigation of ultimate strength issues. The review of the past use of doubler plates will include consultation with shipyards that have installed doubler plates as temporary repairs and with shipyards that have had to remove them to perform permanent repairs. Means will be found to reduce corrosion when doublers are placed over a corroded plate to which seawater may still gain access. Design of doublers will be developed of maintain the original structural integrity, including ultimate strength and fatigue and fracture strength. Chapter 100, Hull Structures, of Naval Ships' Technical Manual will be reviewed and a plan developed for updating it to reflect the results of the proposed research as well as other developments in the maintenance, inspection, and repair of ship structure. A plan will be developed for a Phase II effort to experimentally verify the results of the Phase I effort.A significant reduction in the cost of structural repairs to U.S. Navy ships is anticipated if doubler plates are used as permanent repairs. Avoidance of drydocking for structural repairs can save several hundred thousand dollars per repair. If there were only one such instance per year, the U.S. Navy would save several million dollars over a 10 year period, quickly amortizing the investment in this research. Commercial structural design standards such as those contained in the classification societies would benefit as new performance data of doubler plates is incorporated. This would lead to better monitoring & inspection procedures for these repairs as well as provide a more cost-effective strategy for decisions to permanently repair doubler plates.

Title:Wireless Interface to Programmable Logic Controllers (PLC)
Abstract:The installation of Programmable Logic Controllers has become an integral part of shipboard control system. The most popular method for PLCs to communicate with external devices is through RS-232 connections using the MODBUS protocol. Newer PLCs support DeviceNet, ControlNet, or Ethernet networks, as well as Data Highway Plus, RS-232C, RS-422A, or RS-423A networks. As the Programmable Logic Controller becomes more prevalent throughout the ship, the use of RS-232 communication techniques increases the cost of the installation. In an effort to reduce the installation costs of shipboard control system, wireless communication to and from the PLC is required. This project will develop low-cost, single-chip wireless units for inclusion into manufacturers equipment to allow direct MODBUS (as well as, other standard protocols) communication between PLCs, other PLCs, SCADA equipment, and HMI interfacesCost Reduction Opportunities Decreased numbers of PLC's ˙ Decreased amount of cable ˙ Decreased number of cable/LAN drops ˙ Faster installation and setup times ˙ Greatly reduced sensor installation cost ˙ Quicker system debug and fault isolation Decreased installation of shipboard control and monitoring systems Potential Commercial Applications Potential Commercial and Military Market Opportunities ˙ Monitoring and control of factory floor ˙ Power plant monitoring ˙ Monitoring proper curing of molded materials, cements, concrete, etc ˙ Monitoring the temperature of sensitive explosives to warn of dangerous situations ˙ Monitoring the integrity of sealed containers ˙ Cutting tool feed mechanism control ˙ Process control in refinery and petroleum industry ˙ Turbine operation and state monitoring ˙ Pulp and paper feedwater monitoring ˙ Monitoring of machinery condition in dangerous, hard-to-reach or moving sites ˙ Water/Wastewater control ˙ Material handling and shuttling ˙ Lighting control

Title:Wireless Interface Modules for Programmable Logic Controller (PLC) Communications
Abstract:The installation of Programmable Logic Controllers (PLCs) is a major cost driver for shipboard controls and monitoring systems. The proposed effort will develop and demonstrate a wireless interface for PLC controllers within a shipboard environment per the Navy's instrumentation requirements. All situations where reliable, low cost wireless links are established in lieu of wires/cables will directly result in major savings to the Navy during both the installation and maintenance lifetime and will result in reduced weight of the instrumentation system. Luna Innovations and its development team will first determine the best suited wireless technology for shipboard application (audio, radio, infra-red, etc), and develop a suitable wireless communications concept for shipboard data transfer while providing a cost effective approach. The research will focus on commercial-off-the-shelf (COTS) technologies and standards such as 802.11 and Bluetooth, resulting in modules that will communicate PLC information directly to a remote centralized control room, requiring non-line-of-sight transmission capability. A prototype interface module will be designed, developed, and then demonstrated at the end of the Phase I program. Luna will leverage previous wireless sensor development efforts and commercial production capabilities to satisfy the Navy requirements and bring the technology to immediate application and near-term product sales. Luna Innovations anticipates large non-defense related markets in industrial control systems, with specific applications including shipboard, spacecraft, aircraft, and nuclear/conventional power plant instrumentation systems. The previous success in this area resulted in a spin-off company dedicated to the production of wireless instrumentation systems for industrial rotating machine health monitoring utilizing off-the-shelf RF technology, and has over $1 million/year in revenue. Products resulting from this research will undergo immediate transition for introduction to the market.

Title:Portable Wireless Vibration Monitoring System for Shipboard Applications
Abstract:The rapid development of wireless technology is creating new opportunities and challenges for instrumentation users and suppliers. Wireless sensor systems can significantly decrease instrumentation set-up time and cost, while simultaneously improving sensor signal-to-noise ratios and instrumentation system flexibility. Further, the arduous task of manually collecting accelerometer samples for purposes of machinery health assessment has created a situation where a wireless data conditioning and collection approach would have many benefits; primarily a reduction in man-hours devoted to data collection and reduced instrumentation installation and maintenance costs. Unfortunately, no wireless accelerometer systems are currently available that meet the needs of the Navy's Assessment of Equipment Condition Program and similar harsh environment applications. Luna Innovations proposes to develop a miniature, robust, low power, wireless system for measuring vibration utilizing the emerging RF and MEMS technologies with the primary objective being a target cost and performance equivalent to standard cabled accelerometers. This system will encompass both the sensor and the mobile unit used to collect data from multiple sensors in high-temperature, high-acceleration shipboard environments. Luna and its commercial partners will leverage previous wireless sensor development efforts and commercial production capabilities to satisfy the immediate Navy requirements and bring the developed technology to near-term market. Luna Innovations anticipates large non-defense related markets in industrial preventive maintenance systems and diagnostic instrumentation coupled with wireless transmission capability. Specific applications include shipboard, spacecraft, aircraft, and nuclear/conventional power plant health monitoring, transportation vehicle design and testing, and industrial rotating machine monitoring. The previous success in this area resulted in a spin-off company, dedicated to the production of wireless instrumentation systems for industrial rotating machine health monitoring utilizing off-the-shelf RF technology, and has over $1 million/year in revenue.

Title:Conventional and Revolutionary Material Solutions for Composites Hatches and Scuttles
Abstract:KCI, working with Bath Iron Works, proposes to design, develop and ultimately (in Phase II) install composite hatches and scuttles on DDG51's for sea trials. Our Phase I program has two important parts. First, we will select three DDG51 hatches and/or scuttles and develop replacement designs based on conventional composite material and processing technology. We expect leading designs selected in a Phase I trade study will be E-glass fiber reinforced sandwich panels produced by VARTM processing. We will investigate numerous matrix options including vinyl ester and epoxy loaded with fire-retardant thermosets, phenolics and new materials such as phthalonitrile, to deveop a design that cost-effectively meets MIL-STD-2031 requirements plus goals for weight and impact resistance. We will consider skin-stiffened designs as a potentially superior configuration to damage-prone sandwich panels. A second and perhaps far more important component of our Phase I research will be an investigation of a conceptual tri-component material system termed KCISTM. In Phase I will fabricate KCISTM test specimens and subject them to mechanical, EMI and FST testing. If this new materials technology performs as expected, it could be nearly impervious to expected shipboard fires conditions and could revolutionize the application of composites to shipboard structures. Demonstration of technology for making light-weight, cost-effective, damage-resistant composite hatches and scuttles accepted for use on DDG51 will open a market for similar products on a vast array of commercial and military ships. The same composite technology demonstrated for hatches and scuttles could be applied to a wide range of other shipboard structural parts. A new technology concept, KCISTM, if proven to perform as postulated in this proposal, could revolutionize the entire high temperature and fire-resistant composites industry by providing a material that is nearly impervious to fire at a cost that is competitive with conventional composites meeting the same performance requirements.

Title:Low-cost Molded Polyparaphenylene Scuttles and Hatches
Abstract:We propose using our unique, self-reinforcing, rigid-rod, polyparaphenylene-based thermoplastic for fabricating low-cost, lightweight scuttles and hatches. This thermoplastic, named Parmaxr Self-Reinforced Polymer ("SRP"), is an extraordinary high-performance polymer that exhibits the strength of metals. Parmaxr SRPs, however, are not long fiber composites, and thus are readily fabricated using conventional low-cost, automated molding methods. The most elegant design solution for hatch and scuttle fabrication is single operation molding. This is not possible with current sandwich-core composite technology, which requires complicated lay-ups. For scuttles and hatches, use of Parmaxr SRPs will offer the following advantages 1) lightweight, possibly including a Parmaxr SRP foam core (sandwich structure); 2) charring, providing an insulating, protective layer in fire situations without toxic gasses; and 3) simplified compression manufacturing methods, enabling production of cost-effective scuttles and hatches. During Phase I we propose to 1) compound Parmaxr SRPs into suitable formulations (ensuring acceptable mechanical, weight, EMI shielding, maintenance, and fire tolerance properties); 2) fabricate and test specimens to qualify formulations for use (with an emphasis on fire situation properties); 3) enter into a collaboration with one or more existing manufacturers of scuttles and hatches for development work; and 4) design prototype scuttles and/or hatches for Phase II development.Lightweight thermoplastic hatches will be commercially viable products to support the commercial cruise industry and perhaps even specialized fire door markets. This technology will offer high quality, low maintenance, low weight and potentially high volume/ low-cost conformal shape doors for commercial and DOD applications.

Title:Lightweight Advanced Composite Hatches and Scuttles
Abstract:Triton Systems, Inc. proposes to design and develop a lightweight hatch/scuttle using a combination of advanced hybrid metal/polymer matrix composites, fire resistant polymer, and electro-magnetic interference (EMI) shielding polymer for the DDG 51 surface combatant. This combination of materials and processes enables the fabrication of a hatch/scuttle that meets the major design criteria of damage tolerance, EMI shielding, fire resistance, dimensional stability, low weight, low maintenance, and low cost. The hybrid metal/polymer composite is a structure that allows a direct transition from metal matrix composite to polymer matrix composite with efficient load transfer. In addition, the structure allows the co-mingling of metal matrix composite with polymer matrix composite in a unified structure, enhancing damage tolerance and EMI shielding. This approach also allows the co-casting of all of the closure, hinge and sealing fixtures simultaneously, reducing cost. Triton's InstaShieldä polymer will be used for all external gluing, such as gaskets and seals. InstaShieldä is a new conductive resin system that is formulated to high performance EMI shielding specifications, both for advanced composite laminations and adhesive applications.The composite hatch/scuttle proposed for development on this program is expected to have a direct impact on the DDG 51 ship by lightening the hatches and scuttles and reducing maintenance costs. Additional near term Navy applications include the DD21 surface combatant for the 21st century and retrofit onto other naval vessels requiring lower maintenance costs and lighter hatches. Commercial applications include hatches, scuttles and doors for commercial cargo vessels, and commercial cruise liners. Additional applications include missile casing end fittings, space truss tube end fittings, bicycle frame fittings, automobile frames, bodies and joints, drive shaft end fittings, propeller hub assemblies and airframe components of all kinds.

Title:Development of Probabilistic Design Primary Loads (Vertical & Lateral Bending) for use in a Weight-Optimized Structural Design of CVNX
Abstract:The objectives of Phase I are to develop realistic, extreme primary hull girder loads necessary to facilitate the application of reliability-based methods for investigating the possibility of weight savings for aircraft carrier. In this study, an empirical-analytical methodology will be developed based on sea trials, spectral analysis and extreme value analysis that uses empirical data, operation profiles and motion analysis. The specific tasks needed to achieve these objectives of the proposed effort can be enumerated as follows: 1. Definition of reliability-based design and its needs in terms of load definition; 2. Assessment of primary loads; 3. Probabilistic characteristics of primary loads; 4. Extreme value analysis to determine the probabilistic characteristics of primary loads; 5. Load combinations; 6.

Title:Development of Probabilistic Design Primary Loads (Vertical & Lateral Bending) for use in a Weight-Optimized Structural Design of CVNX
Abstract:One of the principle objectives of the project is to reduce construction weight of the CVN(x) and similar naval vessels. With this in mind, it is important to consider all loads influencing members scantlings. Some of the member scantlings are governed by local rather than global loads. Because of this concern, both local and global environmental loads will be investigated in this project if awarded to Mansour Engineering, Inc. In Phase I of the project, an operational profile will be constructed for the CVN (x) in consultation with NAVSEA and NSWCCD personnel, consistent with her service life requirements. Based on the operational profile and wave statistics in areas of operation, a multi-dimensional matrix of sea state (H1/3, Ta), heading angle (0), ship speed (V) and loading condition (W) will be established. A probability of occurrence of each "cell", i.e., each combination of (H1/3, Ta, q, V, W) will be estimated. The time domain computer program LAMB will be used to obtain the response of the ship in each "cell". The response shall include ship motion, global loads such as vertical and lateral bending moments as well as local loads in the various regions of the hull. As much as possible, slamming loads will be included. Long term distribution of ship motion and global and local loads will be determined, and from these, life time extreme values will be estimated. These values may be used as design loads or for guidance in determining member scantlings. Mansour Engineering, Inc. has been awarded and successfully conducted similar work in SBIR project "Reliability of Ship Structures," SBIR N00024-94-C-4059. In Phase II of the project, the strength aspects will be developed, including appropriate limit state equations for global and local structure requirements. As much as possible, the effect of fabrication imperfections on member strength will be included in the limit state equations. Mansour Engineering, Inc. has been awarded and has successfully conducted an SBIR project on this subject, "Structural Fabrication Tolerances and Structural Details," SBIR contract no. N00024-96-C-4123. In Phase III of the project, a weight optimization of the midship section will be conducted based on the extreme loads developed in Phase I and the limit state equations developed in Phase II. The proposed principal investigator, Dr. Alaa E. Mansour has conducted a similar study titled "Reliability-Based Method for Optimal Structural Design of Stiffened Panels," Journal of Marine Structures, Vol. 10, No. 4, June 1997. In addition to the principal investigator, there will be co-workers specialized in Naval ship technology including Dr. Robert Sieleski and Dr. Woei-Min Lin who was responsible for the development of the LAMP software at the Science Applications International Corporation. Significant weight savings in construction of the CVN (x) and similar USN ships are expected if it is demonstrated that an optimized midship section can be achieved with no decrease in structural integrity relative to an existing carrier. This has been demonstrated in other engineering fields (offshore, civil and mechanical) where weight savings can be accomplished when reliability-based structural design methods and optimization techniques are used. The proposed principal investigator is currently conducting a reliability-based study for ABS to reduce structural weight in the design of bulk carriers in order to modify Safe Hull Rules.

Title:Relay Replacement
Abstract:The objective of this proposal is to prove the feasibility of building high-power Solid State Relays (SSR) using power MOSFET technology, and specifically to produce a unit to replace the Navy N-130 relays. Power MOSFET technology affords the capability to switch high voltage power at high currents with little on-resistance.Solid State Relays built with MOSFETs offer a number of advantages over SSRs constructed from SCRs and TRIACs, such as: lower on resistance, better control signal isolation (coil to contact isolation in relays), higher efficiency, and higher power handling capability.This research will result in the capability to produce efficient Solid State Relays that operate at higher voltages and currents than are currently available. These SSRs will have application in commercial power switching, telecom, and test equipment, where the use of electromechanical relays is currently the standard.

Title:Relay Replacement
Abstract:The Phase I objective of this R&D project is to confirm the feasibility of developing a solid state relay (SSR) to replace the problematic electromechanical relays in the automatic bus transfer (ABT) control circuitry of the in-plant load centers onboard CVN 68 class ships. The feasible design will closely match N-130 performance characteristics and have substantially increased reliability, low maintenance, the ability to accommodate six current configurations and cost significantly less than the $1800 replacement electromechanical relay.Anticipated Benefits: The solid state relay design will exhibit greatly increased reliability, low operational and replacement cost. It should be noted that the replacement cost for electromechanical relays is not guaranteed to remain approximately $1800 nor would it be unreasonable to expect the electromechanical relay failure rate to increase as the population ages. A successful SSR design could eliminate the probable prospect of substantially increasing electromechanical relay maintenance costs. Potential Commercial Benefits: The reliable, compact, flexible and cost effective design anticipated would permit pursuit of applications using the same or similar devices which in and of themselves would not justify the engineering and manufacturing costs necessary to develop solid state replacements but could use directly or with minor adaptation the replacement relay developed under this program.

Title:Ship Hull Intelligent Protection (SHIP) using Data Mining Techniques
Abstract:The ultimate goal of this effort is to develop state-of-the-art software that performs data fusion on ship hull sensors including reference cell voltage, hull polarization voltage, hull current, salinity, temperature, etc. This research will lead to the optimal control of the Impressed Current Cathodic Protection (ICCP), the prediction of failures like paint removal, remaining anode life, and bridge formation as a means for reliably estimating the remaining life-cycle and planning for dry docking and other condition based maintenance (CBM). Reliable prediction and mitigation of hull corrosion is one of the single most important aspects for the condition-based maintenance (CBM) of the seawater system. No commercial product for performing this task is currently available.Extending the interval between dry docking periods one cycle (18-24 months), would allow substantial savings of over $8.6 million dollars per year for a fleet of 56 ships. The technology developed in this research would reduce the life cycle cost and increase the availability of the fleet.

Title:Low-cost gaseous and liquid oxygen production system
Abstract:Requirements for oxygen production aboard aircraft carriers are changing. As more aircraft are converted to OBOGS, the need for liquid oxygen is decreasing. However, LOX requirements are not expected to drop to zero for a decade or more. For the next decade, there is a clear need for a flexible, compact system to produce LOX in small quantities. Mesoscopic Devices proposes to develop a compact gaseous and liquid oxygen production system using both gas-phase and cryogenic separation to yield a high-purity oxygen stream in a compact, modular system that can be baselined into new ships or retrofitted to existing ships. Our baseline design uses an innovative large-capacity pulse tube liquefier and high performance compact heat exchangers to yield high efficiency and long life. With no moving parts at the cold end, the system is tolerant of shock and vibration loads. The system can be configured to produce liquid and gaseous oxygen in any combination and is scalable to meet future needs. In Phase I, we will identify the most promising separation approach, define the optimum system configuration, and design the baseline system. In Phase II, we will build and test a complete oxygen production system.

Title:Fully Automated Cargo Handling System
Abstract:Automated storage and retrieval systems have proven effective methods of increasing efficiency and lowering overhead costs in many land-based industries. Implementing such systems in Navy aircraft carriers is the objective of the next generation CVNX aircraft carrier. Automated or semi-automated storage and retrieval systems (AS/RS) improve the efficiency of and reduce manpower required for storing, retrieving and tracking inventory. An (AS/RS) decreases time needed to resupply the ship and retrieve supplies on demand, while increasing the stowage capacity of the ship, a direct result from more efficient use of manpower and space in the cargo hold. Before a system concept can be developed to fit (or retrofit) the aircraft carrier or any vessel, a thorough spatial analysis must be performed to assess feasibility. This analysis will allow insight into design content selection, clearly show features most critical for a successful systems operation, and provide information for simulating the entire system. Thus, development time and cost of the scaled model in Phase II will be reduced, allowing for more effective design efforts to be spent on creating an evolutionary, cost effective, rugged, user-friendly, and operationally reliable S-AS/RS, which satisfies shipboard constraints and restrictions. No strike down is required.Development of this automated or semi-automated storage/retrieval system AS/RS as described in this proposal will benefit many existing industries by providing a low cost, reliable system which will improve inventory tracking and maximize storage density. Currently, billions of dollars are spent annually on the installation, maintenance and management of inventory through the use of existing storage and material retrieval system. The simplicity of the proposal concept, coupled with its multidirectional capability by use of multiple transporters will enable many businesses to automate their material handling of inventory, whereas in the past this was cost prohibited. Thus, they will become more cost competitive and profitable. Industries that will benefit include but are not limited to: military logistics commands, distribution warehouses, assembly lines, baggage handling (both airline and cruise ship), and parcel/package services such as FedEx, UPS, and the U.S. Postal Service. This system will also translate into future applications in the medical industry for homebound and handicap patient mobility.

Title:Autonomous Mobile Cargo Handlers For Carrier Automation
Abstract:Operational requirements of the next generation aircraft carrier (CVNX) demand a level of hardware and software automation which current technologies have yet to meet. Of critical importance is the dramatic reduction of crew size. Orbital Research proposes the development of an advanced, robust, and reconfigurable autonomous handling mechanism designed to relieve sailors from physically exhausting manual labor associated with load transport, particularly during underway replenishment (UNREP). In Phase I of this work, Orbital Research will develop a discrete event simulation of cargo handling operations on board an aircraft carrier. This simulation will be used to conduct a system integration study of an Autonomous Mobile Cargo Handling (MCH) device that optimizes the logistics of the transport of stores and munitions on aircraft carrier. Phase I will close with a hardware design and a simulation optimization for the MCH device. Results will be leveraged into Phase II where a detailed, realistic scale model will be designed and constructed that will be mounted on a ship motion simulator.The Orbital Research modular flexible Robotic Materials Handling System is a readily adaptable design giving it diverse commercial applications. Commercial applications include: handling heavy payloads in difficult environments such as heavy manufacturing facility automation, metal forming operations, large component assembly processes, high speed flexible manufacturing for large scale components, and underway ship automation.

Title:Shipboard Bio-mechanical Oil Water Separator
Abstract:In a ship's bilge, water mixes with oils, cleaners, and other liquids and dissolved solids to form a complex wastewater solution harmful to the marine environment. Naval vessels carry onboard oil/water separators (OWS) to prevent discharging oily wastes overboard. OWS systems can remove oil from water; however, serious problems arise when other contaminants, like detergents, are present. These ingredients cause oily water to form an emulsion, which fouls the OWS and prevents proper operation. Thus, the navy is seeking improved methods of separating oils from bilge water and preventing discharges of oily wastes. Acceptable techniques must be compact, automated, and effective on a wide range of waste compositions. Electrocoagulation (EC) is a method of electrochemically inducing coagulation of dissolved ions, oils, or suspended solids to create a readily separable phase. EC effectiveness has been demonstrated on heavy metals, fats, oils & grease, coal fires, and bacteria. However, use of the EC process has been limited due to its inability to effectively compete with land-intensive, chemical coagulation processes. ADA proposes to develop and demonstrate a shipboard EC system that will take advantage of key EC attributes - compact size and broad applicability - to enable this technology to be used for marine applications. The EC process can remove oils and dissolved metal ions from diverse wastewaters and can function as either a primary treatment step or as a pretreatment to other processes. For shipboard operation, EC attributes like compact size, diverse applicability, and minimal reagent usage become key advantages. A successful project will demonstrate EC's ability to treat oily wastewater to the targeted 15 ppm oil concentration regardless of the presence of detergents, solvents, and other contaminants. ADA's existing manufacturing base will be applied to provide these units for marine use.

Abstract:The objective of this proposal is to develop and demonstrate a high volume underway replenishment circulating ropeway system to transfer stores and ordnance to aircraft carriers from supply ships. Circulating ropeway concepts will be developed and evaluated for at-sea future underway replenishment needs. Adaptation of circulating ropeway technology to existing replenishment installations will be considered.The anticipated result of the project is the conceptual development of a circulating ropeway system that will be used for future transfer of stores and ordnance to aircraft carriers from supply ships. Adaptive technology has the potential to increase the range of commercial applications for circulating ropeways where large differential movements or changing positions of terminal points are required.

Title:High Volume Underway Replenishment Circulating Ropeway
Abstract:Weidlinger Associates, with John J. McMullen Associates and Leitner Lifts USA, will develop a high volume underway replenishment system. Several innovative circulating ropeway approaches will be investigated Weidlinger is responsible for the overall management of the SBIR effort and provides expertise in structural design, analysis of dynamic systems, and cable design and inspection. The performance of the cables in a marine environment and the dynamic and fatigue issues will be addressed. McMullen provides expertise for issues associated with ship architecture, including design and evaluation of the onboard equipment and components associated with the UNREP system, personnel and operational issues associated with the operation of the system, and compatibility of the system with other requirements of the delivery and receiving vessels. Leitner provides expertise on rope transport systems pertinent to the design, assessment and construction of the system and test models. The candidate approaches include a Simple Mono-Cable Rig, a Modified Mono-Cable Rig, a Bi-Cable Send / Mono-Cable Receive Rig, a Single Bi-Cable Rig, and a Dual Bi-Cable. The team will use a formal trade study process to evaluate the alternatives using weighting criteria developed with input from the Navy. One or two rigs will be selected for further development. As the size and capability of commercial marine vessels increases, one would expect an increased civilian demand for enhanced replenishment capability. Also the potential development of new sending, supporting, transporting and/or receiving components could find application in commercial funicular applications. Finally, adaptive technology has the potential to increase the range of commercial applications for circulating ropeways (for example, transferring loads and people directly from ships to tops of mountains and cliffs). There are potential applications for replenishment systems for drill ships and drill barges as well as floating production, storage and offloading systems, mobile offshore drilling units and undersea pipeline systems and risers.

Title:Water-Wet Pelletized Nitrocellulose Dehydration
Abstract:Apogee Engineering Inc. proposes to R&D a unique process for dehydrating a slurry of 10% pelletized nitrocellulose (PNC) in water, ending with a final product of 60% PNC in a n-heptane slurry with a maximum of 0.1% water. The existing process involves drying the PNC to dryness in ovens and handling trays of material manually, then mixing it with very low flash point n-heptane. One can draw their own conclusions regarding the safety of this process. The Apogee goal is to use the best available technology so that the resulting process is: Operable and performs as required, Safe, Continuous, Energy and environmentally efficient, Minimal capital and operating cost and Composed of robust unit operations and equipment. Five options for processes have been proposed for evaluation and several others considered and rejected. The best process may be a combination of unit operations selected from among the five options. Membrane technology will probably be used. Principle investigator, David Lee Tanner,P.E. chemical engineer with over 45 years experience in diverse technologies, will establish the correct design basis for the process. A robust and superior process will be developed that will meet the needs of the Navy, other DOD components and the private sector.Benefits to the Navy, as a result of this research and development, will be the creation of a safer, automated and less labor intensive process for the dehydration of their pelletized nitrocellulose for use in composit cast modified double base explosives. The technology developed will also be of benefit to other DOD components. Apogee employees have conceived a unique processing step utilizing pervaporation membranes that may have utility in the pigment and dye industry, the pharmaceutical industry and the explosive and propellant industry in the private sector. This technology is anticipated to be patentable based on a percursory patent search. Successful development of this technology and obtaining patent rights would lead to a partnership with an established equipment manufacturing company that would be in a position to market this technology to an established customer base with an established marketing structure.

Title:Dehydration of Water-Wet Nitrocellulose by Enhanced Leaching Operation
Abstract:AVEKA proposes the use of one of its proprietary leaching processes to dehydrate water-wet pelletized nitrocellulose (PNC). This is a process which will be safe, economical and will allow continuous processing during the dehydration step in the pelletization process. It is also a process that can utilize standard industrial leaching/extraction equipment with some modifications. The successful completion of this phase I research will be the adaptation of the AVEKA process to process the water-wet nitrocellulose into heptane dispersion without exposure to high temperatures and without changing the product characteristics. Phase II of this research will scale-up this process to production for integration into the present Navy facility for this process.The potential commercial applications for this water extraction technique are industries which presently deal with temperature sensitive materials and have a need to dehydrate or dry them. This process will be adapted for usage in the pharmaceutical and biochemical industries to dehydrate drugs and biologically derived materials which undergo decomposition at high temperatures.

Title:Improved Magnetostrictive Composites
Abstract:The DOD has identified a need for high power broadband hybrid transducer arrays for use in surface ship sonar systems. The hybrid transducer design incorporates both magnetostrictive and piezoelectric elements into a novel double-resonant system that provides a previously unattainable bandwidth and power combination. The device currently incorporates laminated Terfenol-D materials for the magnetostrictive drive element. However, the laminating approach limits the design scope of the transducer device due to both limitations in lamination thickness (bandwidth) and stiffness properties available. These limitations can be overcome by replacing the laminated Terfenol-D elements with a robust magnetostrictive particulate composite assemblage described in this proposal. Development of magnetostrictive material that has tunable stiffness properties and large piezomagnetic coefficients. Commercial applications include sonar and hybrid sonar devices.

Title:Enhanced Crystalline Alignment of TERFENOL-D
Abstract:The effort proposed will validate the methods needed to achieve an enhanced crystalline structure in TERFENOL-D drivers. These new materials are expected to show substantially increased magnetostrictive performance (20-40% increase in strain, 10-20% reduction in hysteresis) as compared to baseline, large diameter ECG materials. This performance is expected to be on a similar level to FSZM materials, but will be available in much larger diameters than the 8mm maximum of FSZM. In Phase I, a rudimentary method for achieving enhanced crystalline alignment will be proven. Some of the critical process parameters will be explored, and others will be defined. In Phase II, this foundation of information will be used to develop a full scale process for reliable, day-to-day production of these materials. Phase II will also include an evaluation of full-sized samples to directly compare them against drivers in an established configuration. TERFENOL-D is a new competitive technology suitable for several different commercial and military applications, such as fuel injectors, braking systems, semiconductor bonding clamps, mine avoidance/removal, hazardous waste remediation, acoustic sources, dental tools, sono chemistry, construction tools, active machine tool control, rubber recycling, and enhanced oil recovery. ETREMA Products, Inc. was established to commercialize TERFENOL-D and transfer the technology from a laboratory discovery to industry and is now recognized as the world leader in the growing manufacturing sector for this material. ETREMA's marketing history is evident in the corporation's growth statistics. ETREMA has successfully established an international market for TERFENOL-D material, devices, and R&D services to develop solutions for industrial problems. Proof of its success is best illustrated in the year-over-year sales increases running between 50-100% over the last 6 years. ETREMA stands ready to implement any advantageous developments from the proposed effort. Substantial increases in the magnetostrictive performance will only accelerate the insertion of TERFENOL-D into the already growing market.

Title:Improved Magnetostrictive Materials
Abstract:Objectives of this program include the development of magneto-active materials that yield improved performance, such as greater strain and reduced hysteresis loss, when compared to the current parameters of the magnetostrictive material Terfenol-D. We propose to consider the use of a recently discovered class of highly active ferromagnetic shape memory alloys (FSMAs). One of these FSMAs, Ni2MnGa, shows strains as high as 6 % and the possibility of low hysteresis loss; and thus, offers potential as a high-output transduction material. To this end we plan to use current and new measurements on the FSMA material to characterize it for transducer applications by state-of-the-art modeling. R. C. O'Handley's group at MIT will perform the FSMA material measurements. Based on this, analytical transducer models would be developed and used to evaluate the material as a transducer driver in potential transduction devices and applications. Our models would include electrical equivalent circuits, the finite element program ATILA and the program FLEXT. Transducers such the Tonpilz, X-spring and flextensionals would be considered as well as selected actuators. Our results will lead to optimized designs that could be fabricated in a Phase II effort.The development of this technology will permit the design and fabrication of high power actuators and transducers for military as well as commercial applications in the aerospace, automotive and control industries.

Title:Development of Low-Cost Manufacturing Process for 1, 2, 4-Butanetriol (BT)
Abstract:A process to manufacture low cost, high purity 1,2,4-butanetriol for use as a starting material in the manufacture of the plasticizer, 1,2,4-butanetrinitrate, will be developed. The starting material for the synthesis of 1,2,4-butanetriol will be the commercially available d,l-malic acid. The d,l-malic acid will be biotransformed under mild conditions using an anaerobic microoganism to reduce the carboxylic acid groups to the corresponding alcohol groups.An inexpensive source of high purity 1,2,4-butanetriol would allow greater incorporation of the 1,2,4-butanetrinitrate plasticizer in nitrocellulose propellants. Substitution of 1,2,4-butanetrnitrate for nitroglycerin in these propellants should extend the life of the propellants and decrease the hazards associated with their manufacture. The optical isomers of 1,2,4-butanetriol are of commercial interest as chiral building blocks for the synthesis of pharmaceuticals and specialty chemicals. The commercial demand for low cost, high purity (both chemical and optical) 1,2,4-butanetriol isomers is expected to increase rapidly in the next few years.

Title:Development of an Efficient Low-Cost Manufacturing Process for 1, 2, 4-Butanetriol (BT)
Abstract:There is a need to replace explosives, such as nitroglycerine, with more thermally stable materials for military and commercial applications. BTTN (1,2,4-butanetrinitrate) meets this need by offering a ten-fold increase in stability. Unfortunately, BTTN is prepared from an expensive material (1,2,4-butanetriol; BT), which currently costs $30-40/lb (compared to $0.50/lb for the glycerine, the precursor for nitroglycerine). For this reason, the Navy is interested in more cost-effective methods of preparing BT. This Phase I effort proposes a two-step, one-pot procedure for preparing BT that is based on well-precedented literature procedures. It is anticipated that this procedure will reduce material costs of preparing a pound of BT to less than $5. The proposed synthesis will be demonstrated in Phase I and scaled up to 30- to 100-gal reactors during the Option Period. The development of a more economically and commercially viable process for the preparation of 1,2,4-butanetriol (BT) would make 1,2,4-butanetrinitrate (BTTN) more affordable for military and commercial use as a stable replacement for nitroglycerine.

Title:Drag Reduction in Water
Abstract:An innovative program is proposed to exploit the dramatic drag reduction potential of microbubble layers on high-speed undersea vehicles. Under the turbulent flow conditions experienced by torpedoes, microbubble drag reduction is capable of providing the maximum friction drag benefit. Previous research has revealed that 80% of the skin friction drag can be eliminated through the introduction of small bubbles into the boundary layer surrounding the vehicle, but the application of the technology has not been vigorously pursued. The focus of this effort is to obtain extreme drag reduction levels by controlling the bubble characteristics and emphasizing techniques for high-speed vehicles. Three methods will be investigated experimentally: porous surface gas flow, water electrolysis and chemical gas bubble generation. All are capable of achieving high drag reduction levels, but the compatibility of each technique with the vehicle power system and weight/volume constraints will be carefully evaluated using an engineering model accounting for energy costs and system efficiencies. In the Phase I effort, experiments will be undertaken to establish the maximum drag reduction levels that can be achieved using controlled microbubble layers. The technique(s) providing the optimum performance and power system compatibility will be evaluated in large-scale experiments conducted in Phase II.The microbubble drag reduction technology is applicable for all marine vehicles. Commercial applications include supertankers, cruise ships, freighters, ferries and private power boats. Navy applications are high-speed torpedoes, AUVs/UUVs, submarines and surface combatants.

Title:Cycloidal Fan for Low-Noise Air Management
Abstract:BOSCH Aerospace, Inc., a service connected disabled veteran-owned small business, is pleased to submit this proposal to develop and demonstrate an efficient, low-noise, low-maintenance air management system for shipboard ventilation. The concept is adapted from the Vertical Takeoff and Landing aircraft Cycloidal Propeller (CycloProp) development currently underway in SBIR Phase II Contract N68335-00-C-0201. CycloProp geometry places wing sections into rotation in a paddlewheel manner. In this geometry, air velocity is equal at all points across each wing's span. During rotation, the wing's angle-of-attack is changed in the sector of rotation requiring air acceleration. The result is very high-thrust and low noise at rotational speeds of about 20% of conventional propellers. CycloProp has demonstrated thrust of over 12 lbs/HP versus about three pounds for conventional propellers. This low-speed, high-thrust capability means less wear on bearings, lower energy consumption, low noise and lower maintenance. The research phases are: Engineering/Design, Fabrication/Integration, Testing/Demonstration. The project documentation will include design drawings, test reports, video, photographs and monthly Cost Performance Reports. Success will be exploited in the commercial sector whereSuccess will be exploited in the commercial sector where low-noise, efficient air movement systems are in demand. Benefits include low noise, low power consumption, high efficiency, and low wear on components, thus low maintenance. Commercial applications include worldwide forced air heat and cooling, electronic cooling applications in space, and other high-volume, low-pressure air or gas movement applications.

Title:Projectile Inertial Navigator from COTS Instruments
Abstract:This topic seeks a gun-hardened inertial navigator, suitable for guided munitions, made from low cost, commercially available instruments. After many years of waiting, and many failed starts, a Commercial Off The Shelf (COTS) 'Chip Gyro' is finally emerging. Analog Devices is sampling to us integrated (all silicon) iMEMS angular rate sensor prototypes designed primarily for the high volume automotive market. We will show in Phase 1 through analysis, simulation and extensive shock testing that these gyros can be combined with existing automotive grade silicon accelerometers and a single chip microcontroller to form a small, low cost IMU that will eventually occupy only 1 cu inch of volume. Performance will NOT be on par with current tactical grade optical and spinning wheel inertial instruments, but we will demonstrate their adequacy, with proper calibration, for dead reckoning ERGM and other guided munitions through the final stages of an engagement when the enemy is likely to locally jam the GPS timing signals. Everyone is excited about the eventual possibilities of MEMS. This project emphasizes the near term development of a low cost, low risk Inertial Measurement Unit based on COTS MEMS.

Title:Projectile Inertial Navigator from COTS Instruments
Abstract:This Phase I study proposes to address the high cost of navigation systems suitable for guidance of gun-launched projectiles. The basic approach to reducing cost is to adapt for this purpose components which are under high rate production for the commercial market. Especially in the case of integrated electronic circuits and microfabricated mechanical devices, high production rate equates to low cost. We propose a navigation system which integrates the functions of an inertial navigation system, a GPS receiver and anti-jam antenna control. The INS is based on hardened versions of MEMS accelerometers and gyros which were designed for the large market in the automotive industry. The modest performance capability of these instruments is accommodated by strong aiding with GPS data. GPS receivers have been manufactured in large quantity for some time, and gun-hard versions have already been demonstrated. The addition of anti-jam signal processing gives the GPS receiver an additional margin of protection against both intentional and unintentional interference. This function is implemented in digital signal processing electronics, and when reduced to ASIC form can be produced at low cost.There is a clear need to improve the accuracy of long range projectiles through active guidance. There is at present no navigaiton capability suitable for this purpose which can be acquired at acceptable cost. This study proposes to integrate a set of components whose costs have been reduced due to COTS applications which will provide the required capability

Title:Projectile Inertial Navigator from COTS Instruments
Abstract:With the development of intelligent gun-launched munitions such as the US Navy Extended Range Guided Munition, there is a strong need for small, inexpensive, rugged and accurate inertial navigation systems (INS). Advances in MEMS sensors, miniature GPS receivers and A/J capability make a GPS-aided MEMS-based INS a strong candidate for this technology The objective of Phase I is to demonstrate the feasibility of a complete COTS INS solution that meets these requirements. Performance prediction of several externally aided INS design approaches will be performed. Packaging, electrical, and producibility issues will be addressed along with high-G testing. Phase II will involve prototype development and high-G testing of the proposed integrated INS.The potential commercial market for such an INS is orders of magnitude larger than any contemplated military market. Current automobile navigation systems rely completely on GPS. The INS would provide the navigation during times of GPS dropout caused by satellite LOS obstruction and signal interference. Other markets include commercial and private aircraft navigation and control, robotics, toys, medical equipment, surveying equipment, Geographic Information Systems, self-documenting digital photography systems used in highway maintenance, crime scene documentation, and insurance investigation.

Title:PBO Fiber-Reinforced Hydrocarbon Resin Composite for Low-Density, Wide Frequency Range Sonar Domes
Abstract:Shipboard sonar domes based upon steel fiber-reinforced rubber currently show unsatisfactory performance as a result of narrow operating frequency range, high acoustic insertion losses and corrosion of metal fibers. Foster-Miller proposes to combine and extend our successful hydrocarbon resin, PBO fiber,VARTM and acoustic window technologies to develop a new class of sonar dome that is low density (1.23g/cc), hydrophobic, structurally sound and acoustically transparent over a wider frequency range than current sonar domes. Our low viscosity hydrocarbon resin will be VARTM-processed using low density (1.5g/cc), high performance PBO fiber preforms into a damage-tolerant, PBO fiber-reinforced, hydrocarbon resin sonar dome, called the Low Density Sonar Dome (LDSD), in one automated step. The LDSD will exceed the performance of current sonar windows, be lighter in weight and more economical. In Phase I, we will produce the LDSD and conduct acoustic testing to demonstrate feasibility. In Phase II, we will refine the material and process, scale-up to larger, more complex composite test specimens and conduct extensive acoustic and mechanical testing to qualify the LDSD for use in Navy shipboard applications. Our team includes experts in PBO fiber composites, hydrocarbon resins, VARTM processing and acoustic testing and Raytheon. (P-01401) The Foster-Miller LDSD will provide the U.S. Navy and commercial shipping industry with a sonar dome that is lower in cost, more durable and broader in acoustic frequency range than current shipboard sonar domes. Commercial applications include shipboard sonar domes and windows as well as other acoustically transparent, water-resistant composite structures such as remote submersible vehicles.

Title:Improved Sonar Dome Window Materials that are Acoustically Transparent across a Wide Frequency Range
Abstract:Current sonar domes do not provide best performance acoustically such as the insertion loss is high at high frequencies. Also, they do not cover wide band of frequencies of interest. Sonar domes materials have changed very little for over 20 years. There are new materials in the market which should be evaluated for the Navy applications.Development of the new material can be used for fishing boats, and radar domes for the aircraft industries.

Title:Innovative Fiber Reinforced Composite Materials for Acoustic Window Applications (MSC P1B16-102)
Abstract:Material systems that meet the insertion loss (IL) requirements of current acoustic windows have been shown to have difficulty meeting the structural properties required for undersea operation. In this proposal, Materials Sciences Corporation (MSC) outlines a research program to develop and demonstrate new and innovative fiber reinforced composite material concepts that have low IL across a wide frequency range yet have stiffness and strength characteristics necessary to survive undersea operational loads. The material solutions to be investigated will not rely on a tuned core to provide the required insertion loss characteristics; rather MSC plans to investigate innovative continuous fiber reinforced composite designs that are compatible with a low-cost composite manufacturing process. The leading candidate is a hybrid construction, comprised of a small amount of specialty glass and organic fiber reinforcement, that results in a composite material with a characteristic impedance that is acoustically transparent across a wide frequency range. Laboratory tests will be conducted to provide acoustic and structural response data needed to validate analysis tools used to select promising material candidates. Once validated, these analysis tools will be used to evaluate alternate acoustic window designs for sonar array systems proposed for the DD21.The leading application for the materials developed under this effort will be higher performing acoustic windows for use in U.S. Navy combatants such as the DD21 and submarines produced by Bath Iron Works, Litton/Ingalls Shipbuilding, and Electric Boat Corp. In addition to these direct applications, MSC will pursue application of the products of this SBIR to commercial sectors, which transmit acoustic signals through materials, including those in the fishing industry, the oil exploration industry and the medical industry.

Title:Automatic Code and Data Migration in a Networked Computer Environment
Abstract:In the DoD, many systems operate in multiple computer networks. Therefore, if a particular computer goes down, disabling the functions it performs, critical systems would be unavailable. If these functions could be moved to another hardware platform, no disruption of critical services would ensue. Cybernet has a patent for combining an Internet router with an applications-specific execution engine that caches algorithms. In this proposed effort we will extend the concept to routers that cache arbitrary code (not just code for message parsing and culling) for execution. The idea is to put a JAVA-like execution engine into all routers. Cybernet will:1) Develop a means that allows URLs to be resolved to where a dataset or function is cached, and not to a strict physical location,2) Develop an algorithm for moving datasets and functions from machine to machine,3) Develop a set of intelligent network and traffic monitoring/diagnosis processes, 4) Define a common runtime cache/shuffle system which is easily ported to each operating system platform, and 5) Determine the best way of bringing code user interfaces to a user who might be located anywhere on the network.A demonstration of this system will be implemented during the Phase I effort.The anticipated result of the proposed Phase I effort is to identify and prototype new and technically innovative web applications caching technology, which we plan to commercialize via Cybernet's NetMAX product line.

Title:Run-Time Reallocation of Heterogeneous Computing Resources
Abstract:This proposal combines recent developments in the Java and CORBA communities with the real-time capabilities for the CORDS/GIPC group communications system. By enhancing those basic technologies with comonents that provide easily accessible fault-tolerance methods, the resulting system will be useful in military combat systems as well as commercial environments, such as factory floor automation and stock exchanges.This project will produce a system in which only one form of executable object exists, and that object can execute on any node regardless of the underlying platform. The system enables the development of efficient implementations of real-time, fault-tolerant applications. The project leverages the existing base of Java and Ada applications and programmers and fosters the creation of code without hidden security risks.

Title:RTRACE - Real-Time Reconfiguration and Control Environment
Abstract:TimeSys will develop the Real-Time Reconfiguration and Control Environment (RTRACE) solution to the reconfigurable distributed software problem by combining several independently developed activities originating with TimeSys technical professionals, both independently and in concert with efforts by the broader real-time systems standards community. We will develop and describe an approach for building an operating environment platform to allow real-time applications to run on multiple processor types. We will develop all of the infrastructure components required to implement typical Navy applications. This will include a RTSJ-compliant Java Virtual Machine (JVM) running on the TimeSys Linux/RT operating system. We will develop and describe an approach for building a distributed operating environment that supports the reallocation of system functions and/or applications across heterogeneous computing resources. We will extend the environment described above to incorporate the solution developed by our involvement in the Distributed Real-Time Specification (DRTSJ) for Java. In addition, we will evaluate CORBA-compliant components that can be used in conjunction with the DRTSJ, especially several components that are compliant with the Object Management Group's Fault Tolerance specification as well as with its real-time CORBA specifications.The proposed work through Phase II and beyond, will help to develop a technical solution that will begin to realize the vision of a truly "plug and play" total ship operating environment.

Title:Fault Location in an Intelligent Open Sensor Network
Abstract:Condition monitoring depends on information that is extracted from data gathered through a well-defined, yet dispersed, sensor network. The combination of embedded, self validating sensors, the development of a widely dispersed self-organizing sensor architecture and the intelligent agent software to facilitate the development and design of an emergent, self aware monitoring system will make available an up-to-date and accurate status, prognostic health assessment, diagnostic, and maintenance procedures. Because of the large number of on-board sensors and the fact that they will be widely dispersed, development of communications and controls technologies capable of coordinating these resources is needed. The intent of this research is to develop the necessary and sufficient connectivity to allow stable operation of a shipboard prognostic and health monitoring system and to formulate it as a dissipative system, able to recover from anomalies and disturbances without compromising mission compliance. We propose to develop a system where dynamics and stability are predicated on changing optimality and that cooperating agents form the basis for such rational behavior. Furthermore, for a system of operating agents to be successful, a communication architecture must be developed that allows for the free flow of data and information unencumbered by any spatial constraints.A successful approach will result in a blueprint for development of a robust, virtually indestructible network that will serve as a high-reliability communications link and sensor network for emergency and crisis management. It is expected to have wide application in areas such as Navy ships, hospitals, emergency response centers, nuclear plants, and any high value industrial asset or process.

Title:A Physics-Based Software Framework for Detection, Location, Isolation and Masking of Faults in Composite Sensor-Computer Networks
Abstract:This Phase I SBIR Proposal responds to Topic 2001.1 Navy01-080, "Fault Location in an Intelligent Open Sensor Network." Proposer, MPI Software Technology, Inc, offers a physical-model-based approach to fault-location, operations-based management, and fault-tolerance of sensor networks. Such systems have relevance to DOD systems, including on-board systems for naval vessels, with corrolary application in other defense and dual-use settings anticipated, including automotive, homes, industrial and space-based applications. The state of the art incorporates stove-pipe subsystems involving sensors, computers, networks, and their separate management, with minimal management and fault-handling interactions. The purpose of this proposal is to create an integrated framework in which the sensors and computers work together in a more tightly coupled manner than is presently done in practice. Phase I studies integrated measurement and computation with the goal of providing enhanced accuracy of sensor measurement through fault-tolerant schemes. Phase II would create a prorotype based on COTS hardware and novel algorithms and software prototypes to be created by Proposer, based on Phase I studies and preliminary findings. Topic Navy01-080 requests fault-detection in sensor networks used in condition-based management of systems of interest. This proposal addresses that requirement, and goes further, offering fault-tolerance concepts, that will enable autonomous operation. Condition-based management can be applied to industrial, automotive, home, and other dual-use settings going beyond military applications. Scientific applications involving integration of measurements and computations are also a valid use, with potential for weather and other applied uses of such scientific computing with high societal value. This concept can be further enhanced to support model-predictive control scenarios of complex systems, which could include autonomous vehicles, or systems operating in harsh environments with no human intervention.

Title:Fault Location in an Intelligent Open Sensor Network
Abstract:The development of complex sensor networks for CBM has created the challenge of assuring the reliable transmission of sensor data across the network and the reliability of the actual data obtained by the sensors. Both classes of sensor and system error - false positives and failure to report a fault - can be costly and dangerous. The probability of these errors must be very low if CBM is to reach its potential. Oceana Sensor Technologies,Inc (OST) proposes to establish a model for self-testing of intelligent sensor networks, including wireless communication links, that can be adopted as an integral feature of emerging intelligent sensor systems. OST recognizes that, with the broad range of sensors and networks in existence and under development, an ad hoc strategy will become an endless series of tasks. Accordingly, OST's approach is general enough to work in any sensor-network configuration.The successful development and implementation of a self-testing CBM network of sensors has many implications. More reliable sensors and sensor networks for CBM give more accurate data over longer operating times. Smart sensors diagnose the exact location of a problem within the network so that humans need to spend less time diagnosing problems. The compliance of the open architecture network in accordance with IEEE1451 standards means it will interface with many vendors' sensors and network systems. And lastly, this technology will apply to any CBM system, DoD or commercial.

Title:Application of JINI Technology to Tactical System Integration
Abstract:As submarine data processing systems become more complex and are comprised of more and more heterogeneous components, a new compatibility problem has arisen. Use of middleware packages, which broker data between applications using unique protocols and standards, has caused inter-subsystem connectivity problems, since each middleware solution, adhering to their own standards, is usually not interoperable with any other middleware. In addition to this problem, many middleware solutions are not backward compatible with previous versions of the same middleware. This situation, whatever the cause, has made a system, which should have a single data exchange standard, now support at least four different standards.At the base of this problem is that middleware products provide a useful service to the applications that use them. Middleware packages provide seamless data exchange services, platform independence, simplified system interfaces, and a standardized execution scheme. In fact, the middleware packages chosen or developed by each subsystem match the needs and requirements of those systems.A desired goal would be to create an architecture for systems to use to insure their interoperability, regardless of the middleware solution each has been developed under. This architecture would allow new subsystems to be integrated into the architecture with little effort.The results of this project are anticipated to have application to both commercial and military systems. Initially, this product would be best applied to government agencies and DoD where there is a real need to provide a better networking solution for system interoperability. In addition, since commercial industry has many of the same networking interconnectivity issues, there is a substantial market for the application of Jini technology in commerce, banking, and transaction-based services where multiple heterogeneous systems must exchange data in a common format.

Title:Application of JINI Technology to Tactical System Integration
Abstract:New standards are emerging for inter-process communication among technical systems under development. Subsystems using the CORBA protocol (IIOP) are sometimes tied to a specific vendor's ORB implementation without regard to portability in a heterogeneous network environment. As technology advances, upgrading is not cost effective. The JINI API, coupled with the Java Naming and Directory Interface (JNDI) API can provide a network architecture with a middleware layer that can relieve clients of many of the housekeeping tasks necessary to maintaining connections between clients and services. This is of particular interest when developing subsystems for the Virginia Class Submarine. One of the NPES subsystems of particular interest is the NTDPS. In this subsystem, laptops are assigned to particular tasks and may be moved to different places in the submarine. Docking ports are available in specific areas of the ship where it is anticipated that the laptops will be used. A wireless solution would be ideal in situations where no docking port is available. Using JINI in conjunction with a Bluetooth, the network can form itself when new hardware is nearby, thus greatly reducing the cost of maintenance and configuration Provides three primary benefits: development of a network infrastructure that provides the framework for extensions that provides inter-subsystem communication and a universal, spontaneous plug-and-play capability; a conceptual network architecture that provides wireless connection for clients and services regardless of location; and development of key services necessary in building a loosely coupled network environment including Accept/Deny procedures, Intrusion detection, Performance monitoring, and Fail over procedures.

Title:Submarine Mast Detectability Reduction
Abstract:Physical Sciences Inc., Sippican, Inc., and ARC Technologies propose to develop thin-film materials for significantly reducing the infrared and visible signatures of submarine masts. The proposed materials incorporate very thin film, conductive polymer electrochromic devices deposited on polymer substrates that can be bonded to existing radar absorbing materials like adhesive tape. The devices provide modulation of their infrared emissivity and visible reflectivity while being highly transmissive to microwaves (1-20 GHz). In Phase I, we will fabricate three different types of devices, measure their electrical and optical switching characteristics, and conduct experiments to estimate their microwave reflectance. We will subject the devices to some basic tests to verify their survival in operational environments. A preliminary system study incorporating the devices, visible/IR background sensors, and control electronics will be conducted. PSI will be responsible for device development and characterization. Sippican will be our commercial partner with experience in submarine mast manufacture; they will guide device development to meet systems integration and Navy requirements. ARC and PSI will perform microwave testing. In Phase II, the devices designs will be developed and optimized, subjected to rigorous environmental and performance testing, and integrated into a laboratory scale demonstration system.The proposed technology has wide applications in both military and commercial sectors. Military applications include US and allied submarines and army equipment. Commercial applications include telecommunications spacecraft thermal control and space electronics systems and electronic billboards and displays.

Title:Low Cost Miniaturized INS for Torpedo Guidance and Control
Abstract:Inertial navigation sensors and system technologies are essential for modern torpedo guidance and control. The objective of this Phase I project is to design a low cost miniaturized inertial navigation system (INS) for torpedo guidance and control using the AGNC-developed coremicroTM IMU. This miniaturized INS is an integration of AGNC's achievements in MEMS sensors and inertial navigation system development. The application of the MEMS inertial sensors makes it possible to build a small, light, low-power, and inexpensive INS. This miniaturized INS meets the torpedo requirements by its small size, light weight, low power, and reduced cost in design and production. It can be used in torpedoes and other vehicles for guidance, attitude determination and control. In Phase I, first, the hardware and software design of a miniaturized INS is proposed and investigated. The system design of the INS makes use of AGNC's rich experience in inertial navigation system (INS) development. Then, based on AGNC-developed technology, MEMS sensors for the miniaturized INS are designed, fabricated and integrated into the system hardware design. Next, an AGNC-developed MEMS testing and calibration system is used for design evaluation. Finally, an accuracy evaluation of the INS is performed by the way of a hardware-in-the-loop simulation.In addition to the application for torpedoes, because of its small size, low cost, and light weight, the miniaturized INS based on MEMS sensors has wide applications in navigation, control, and guidance. Examples of application areas include: miniature underwater vehicles, airborne, land vehicle navigators, micro UAVs, balloon-borne, and spaceborne vehicles, microrovers, micro tracking mechanisms, and space robots.

Title:Torpedo Affordability Improvements through Alternative Gearbox Lubrication and Sonar Transducer Uniformity
Abstract:Oil lubricated gearboxes can be very costly with oil life and maintenance issues, complex sealing, seal shelf life issues, and oil sump requirements. Barber-Nichols Inc. will investigate alternative lubrication concepts to reduce these costs. Investigation areas will be water lubrication, dry or semi-dry lubrication, and material selection. These concepts have potential of significantly reducing gearbox complexity and resultant cost but include the challenges of boundary lubrication, heat rejection, and wear. BNI's experience with very highly loaded gearboxes, gear and bearing design with low viscosity fluids, and extreme applications (cryogenic to 2600F) make them uniquely qualified for success in this challenge. Today's torpedo sonar transducers are manufactured in large lots then individually tested and hand sorted into similar response groups. This hand labor and low yield manufacturing process adds significant cost to sonar arrays. Materials Systems Inc. has a patented injection molding process for piezocomposites that yields a large sheet of very uniform property piezocomposite material. When cut into pieces it provides very uniform elements. MSI has also developed manufacturing process controls and transducer construction methods that provide high electroacoustic repeatability among phased array elements and assemblies. MSI will use this technology to make torpedo transducers more affordable. An alternative lubrication gearbox could allow dramatic cost savings through decreased complexity, elimination of seals and associated shelf life issues, and an integrated feedpump design with resulting part count reduction. Reduction in gearbox size could enable added torpedo range or warhead size. These benefits would increase torpedo affordability. These concepts can also be used in other short life power transmission applications such as aircraft engine oil loss scenarios, missile applications, and space launch vehicle applications. Improving sonar transducer uniformity will also make torpedoes more affordable. If successful, the work performed in transducer uniformity under this program could practically eliminate the hand labor component of sonar assembly cost thereby driving torpedo system cost down. This technology could be used for all sonar applications in Navy and commercial ships, submarines, and other underwater applications.

Title:Data Network for Submarine Command, Control, Communication, and Computers
Abstract:This proposal details a low cost, low risk, innovative approach to implementing a network for connecting sensors to C4 systems within a submarine. Two devices will be built. The first device will eliminate the problem of powering sensors by using a single wire cable to provide power to the sensors. That same wire will also serve as the communication path for all the sensor signals attached to the single wire cable. The second device will be fully wireless. Both devices will be based on a new innovative approach to high bandwidth communication called ultra-wideband communication, where pulses pseudo-randomly modulated in time encode the information, rather than the conventional modulation of continuous waveforms. The wireless sensor link (WSL) and single wire sensor link (SWSL) are not two separate systems. In fact, our concept allows a SWSL unit to be converted to a WSL unit by simply pulling off the battery and antenna module and replacing it with a cable connection module. Likewise, the receiver unit is also the same, allowing signals to reach it via a receiving antenna or cable, but otherwise the electronics are the same. This is because the data is encoded in the same way for both cases.A key opportunity for TM-UWB radio is the industrial wireless LAN market. In 1997, wired LAN equipment sales for Internet service providers alone was $18B, while wireless LAN equipment sales were a mere $213M - a gap that is beginning to close even as the market scale increases. The system we propose offers significant flexibility in using both single wire and wireless nodes in the same network, with the same sensor package, and the same receiving hardware. For equipment health monitoring, our approach is compelling in that it provides a solution to the fundamental problem of how to power the sensors comprising a sensor network. We believe our system could easily become the routine method to interconnect sensors in future military and civilian health monitoring applications.

Title:Wireless Technology for Submarine Communication Systems
Abstract:The rapid development of wireless technology is creating new opportunities and challenges for instrumentation users and suppliers. A significant portion of the cost for design, construction, and upgrade of Submarine Command, Control, Communications, and Computers (C4I) Systems relates to cabling and could be eliminated if wireless links replaced the cables. However, these benefits cannot be realized until the numerous technical challenges to implementing wireless links are overcome. Wireless transmission of data will also offer the potential to eliminate expensive cabling modifications, thus reducing installation and maintenance costs. The proposed Phase I program will first focus on determining which cables in the C4I system that can be replaced and the overall system impact. This includes compatibility and security issues, power requirements, system bandwidth capabilities and the problems associated with RF transmissions. Luna researchers will perform trade studies to assess the feasibility and payback of replacing candidate cables with wireless links. Requirements for those wireless links will be documented and used to evaluate commercial wireless technologies. Luna will draw conclusions about the feasibility of wireless links on submarines, and will offer creative ideas and a plan for adapting COTS products and/or developing new technologies and methods to meet the special requirements. The technologies and methods developed in this program can be applied to numerous military systems, potentially including Naval platforms, shielded data centers, underground command bunkers, and large space-borne equipment such as space stations. Luna also anticipates large non-defense related markets in industrial instrumentation systems coupled with wireless transmission capability. Luna's previous success in this area has resulted in a spin-off company dedicated to the production of wireless instrumentation systems for industrial rotating machine health monitoring utilizing COTS RF technology, and has over $1 million/year in revenue.

Title:Computer Simulation Improvements For Utilization of COTS Equipment in Naval Combatants
Abstract:By improving computer simulation capability for shock isolation systems, this proposal will support the U.S. Navy's efforts to incorporate the use of commercial-off-the-shelf (COTS) equipment items in combat environments. Attention will focus on shock environments, including hostile underwater explosion (UNDEX). Under this proposal, the LS-DYNA finite element software will be enhanced and optimized for application to COTS certification against UNDEX environments. The methods of modal representation, substructuring, and component mode synthesis will be developed in LS-DYNA to greatly enhance its efficiency in simulating the gross structural response of the ship. This will allow simulation detail to be concentrated on the shock isolation system. In the phase I activity, new software features for "flexible-rigid body" modal representation will be implemented, and an anticipated 10x improvement in overall simulation speed will be demonstrated. Interfaces will be added to support user-supplied, potentially proprietary, shock isolation system models. In the phase II activity, substructuring and component mode synthesis will be added to LS-DYNA, an automated simulation procedure will be developed to simplify application of these new methods, and large scale validations of the new software will be performed. The new capabilities developed under this proposal will become a permanent part of the standard production version of the LS-DYNA software.

Title:Transient Shock Resistance of COTS Electronics
Abstract:United States Navy military shipboard equipment designers have utilized of military rated components in their designs together with the application of military specifications to ensure survivability during conflict. These designs were subject to long development cycles and unique point designs with the associated high costs. Due to the rapid growth in commercial electronics, and especially in computing, commercial solutions to shipboard equipment designs have become appealing. Little growth in the defense budget coupled with mandated acquisition reform has led to new shipboard equipment designs with increasing application of Commercial-Off-The-Shelf (COTS) solutions. The positive potential to the Navy in utilizing COTS equipment is enormous. These include the ability to access state-of-the-art technology solutions in its surface ships and submarines coupled with avoiding costly point designs to military specifications. To realize the advantages of utilizing COTS equipment, the uncertainty in understanding the response of COTS equipment to shock loads must be addressed. This will help ensure that the COTS systems will continue to support the war fighter during conflict. Our Phase I research will identify and develop concepts to address and reduce these uncertainties. An improved analytical modeling capability resulting from this research and associated COTS equipment certification process may be used by the commercial shipbuilding industry. This research will allow the evaluation of new designs and associated risks related to vibration and noise control as well as dynamic loads encountered due to wave slamming, sea keeping, grounding, docking loads and collisions at sea.

Title:Low Cost Compression Techniques Applied To Encrypted Data Distribution System
Abstract:The Cooperative Engagement Capability (CEC) was developed to share unfiltered sensor measurements between cooperating units (CU) within the battlegroup. This sharing of information facilitates the development of a common air picture. However, due to bandwidth limitations, there is a limit to the number of units that may receive this information. Data compression techniques can be applied to increase the number of units which are able to exchange these sensor measurements. This Phase I proposal will examine the current state of data compression and develops/analyzes a lossless compression algorithm for inclusion within the CEC's Data Distribution System (DDS).The utilization of a lossless compression algorithm with the Cooperative Engagement Capability's Data Distribution System or any other tactical data link will enhance the information superiority achievable by US military forces.

Title:Low Cost Compression Techniques Applied To Encrypted Data Distribution System
Abstract:What is required is to step "out of the box" and consider solutions that take the needs of a real-time system like the Cooperative Engagement Capability (CEC), as well as the data it is exchanging, into account to design compression solutions that work for the system as a whole. While there may be some development savings in going to the commercial world for these solutions, in the end it is the solution that takes the system into account that will provide the best answer. Progeny Systems has a long history with years of experience in real-time data delivery and processing. Some of the solutions we are providing to the Navy in the Advanced Undersea Warfare Concepts (AUSWC) program solve the same problems in data and bandwidth conservation.The results of this project are anticipated to have application to both commercial and military systems. Initially, this product would be best applied to government agencies and DoD where there is a real need to provide a better networking solution for system connectivity. As such, initial customers are intended to be PMS401, PMS415, PMS425, and PMS450 programs. Since the research is targeted toward interoperability and seamless exchange of information across limited bandwidth channels, the resulting technologies from this topic could be used support most areas of the Navy's system development efforts. In addition, since commercial industry has many of the same networking interconnectivity issues, there is a substantial market for the application of this technology in practical application. During the development cycle, we will be in constant contact with industry, military, and university experts in the related fields. This will also provide us with the opportunity to identify new methods for acquiring better methods and techniques using industry standard development environments.

Title:Novel Data Compression Technique for the CEC System
Abstract:A novel data compression algorithm will be developed for the Cooperative Engagement Capability (CEC) system. Key features of the algorithm include high speed, low cost, and interoperability with encryption. The algorithm will be computationally fast to satisfy CEC's latency requirement. By reducing redundancy in the bit stream, data compression not only will enhance CEC's effective bandwidth but also will enhance security. The compression will be lossless in an information sense. Three classes of data compression methods will be investigated for suitability: entropy-, dictionary-, and prediction-based. Extensive testing and performance evaluation will be performed.Because bandwidth constraints limit the transmission capacity of military and commercial systems, a data compression method that is fast, encryption-capable, low cost, and suitable for use in a distributed system should be of interest to military agencies and commercial entities. Its encryption compatibility should make the algorithm particularly suitable for systems that broadcast proprietary or other sensitive data. The field of wireless communications is exploding and should provide a variety of opportunities for applications in the near future.

Title:Automatic Workload-Sensitive Task Allocator (AWOSTA)
Abstract:The Navy is under pressure to reduce shipboard manning levels in the face of ever-intensifying tactical responsibilities, battlespace tempo, and weapons lethality. There is thus an increasing need for team coordination, cohesiveness, and especially adaptability in operator task allocation during intense tactical operations. We propose to address this by designing a generic distributed agent-based Automatic Workload-Sensitive Task Allocator (AWOSTA) that: 1) identifies, defines, and elicits the static personalities, behaviors, and knowledge of each team member; 2) identifies and assesses the dynamic behavior of the team and each individual member of the team; 3) displays individual and team workload to the team supervisor in an intuitive fashion; and 4) recommends re-tasking options to ensure optimal team performance throughout an engagement. We propose a multi-faceted approach to workload assessment (physiological-, subjective-, and performance-based), the use of belief network technology to combine disparate measures of loading and performance, and an innovative task reallocation logic to optimize team performance. The Phase I effort will develop a prototype to explore the general feasibility of the overall approach. In Phase II we will focus on the design and implementation of a prototype for a specific shipboard system such as the Area Air Defense Commander.The commercial potential for a system with the capability to monitor team workload and stress and the ability to distribute tasks among members of the team based on the measures is very high. Some of the most promising possibilities involve applying the technology in technical support centers, commercial air traffic control, police and other emergency dispatch operations.

Title:Dynamically Optimized Team Performance
Abstract:The System for Management and Allocation of Recurring Tasks (SMART) is proposed to facilitate allocation of team tasks in complex Navy systems. SMART offers a model-based framework for identifying the sequence of tasks which a Navy team performs along with specification of all relevant performance-influencing factors for the team members, tasks, and context. A variety of techniques for task scheduling and allocation will be developed and tested. A cognitive model is employed to specify task dynamics, task interactions, and analytic projections of workload. A user interface for a human task manager will provide a dynamic display of diverse kinds of information that are relevant in assessing the relative effectiveness of different team members in performing different kinds of tasks based on both perseverant and transitory characteristics of the team members, the tasks, and the operational context. Indices of team member cognitive state will include various relevant physiological indicators and some self-report measures for affective factors. Additional indicators of perseverant characteristics such as measures of experience, training, and general mental abilities will also be provided. A series of experiments will start with a completely `manual' scheme for task allocation with succeeding experiments evaluating increasingly complex concepts for aiding and automation of task allocation.SMART is expected to provide a valuable asset for many emerging Navy (and other military) tactical systems which are increasingly comprised of reconfigurable workstations and thus provide broad opportunities for task reallocation as a means to achieve the aggressive goals for reduced manning faced in all new system developments. Non-DoD applications are envisioned for air traffic control, telephone operator management, and other environments with replicated workstations and severe time and workload pressure.

Title:Dynamically Optimized Team Performance
Abstract:A software-based system is proposed, the Dynamically Adaptive Resource Tool (DART), to help operators manage information intense monitoring systems in militarily relevant operational settings. Different approaches to managing team workload overload, under load and losses of vigilance are discussed. The approach with the most likelihood of success is described as a system that uses adaptive automation to enhance information gathering operator resources. It is conceived to be an interface used for both training and operations that 1.) displays the current effectiveness of an operator based on past or expected performance, 2.) provides visual and auditory means to alert the operator to significant decreases in effectiveness, 3.) adjusts information transfer rate and presentation rate based on the operator's effectiveness and 4.) to re-distribute task workload to other team members as needed.The objective of this approach is to integrate sophisticated workload modeling and analysis tools to help manage real-time operator performance. The DART will be able optimize the distribution of information, resources and enhance the performance of the system. Such a tool would be ideal for training since other operators on the team would not have to be present for the system to respond to pre-programmed scenarios.

Title:TBMD Tactical Telemetry Transmitting System
Abstract:Upgraded telemeter requirements for TBMD (Theater Ballistic Missile Defense) post-launch monitoring will include a new tactical mode for defensive operations during armed conflicts. Multiple Standard Missiles from multiple platforms may be launched nearly simultaneously. System analyses have indicated that under this scenario and current IRIG PCM/FM channel allocation guidelines, unacceptable adjacent channel interference will degrade critical telemetry communications. Due to the explosion in commercial wireless communications, further spectral allocations for military telemetry are not foreseen, and current allocations are even being reduced. Thus, improvement in the spectral efficiency of tactical telemetry signals is warranted. Data compression, forward error correction, high-order modulations, and dynamic multiple access techniques can all be applied, as part of a thorough and detailed system analysis to make better use of the available spectrum. In addition to Nova Engineering's substantial experience in solving complex communications problems, the TBMD program would certainly benefit from our Hypermod transmitters and receivers. This innovative technology utilizes SOQPSK and multi-h CPM modulation to provide a two to three-fold increase in spectral efficiency over conventional PCM/FM signalling; prototypes exist today. Detection efficiency approximately equals that of PCM/FM and all modulation schemes have constant envelopes, allowing use of non-linear RF PA's. A set of operational and transmitter requirements developed in Phase I will transition to a high performance telemetry transmitter for NSWC applications, with additional direct application to other DoD flight test ranges and industrial users.

Title:Interference Suppression Techniques Development for Future Combat Scenarios
Abstract:Integrated Sensors Inc. and Syracuse Research Corporation propose to develop and demonstrate techniques that effect practical, operationally meaningful, simultaneous mainlobe/sidelobe jamming cancellation for existing radars while preserving target angular accuracies and permit operation in littoral (clutter) environments. The primary emphasis will be: (a) investigate practical interference suppression techniques for use in existing radars against current and projected interference sources, (b) develop architectural requirements, analyze and quantify detection and target angular accuracy, and (c) demonstrate performance estimates and architectural feasibility. Four associated architectures will be examined: (1) a modified sequential Sum-Difference-Auxiliary adaptation scheme for combined constrained multiple sidelobe canceler/mainlobe canceler operation with non-separable antenna patterns, (2) a Sum-Difference-Auxiliary architecture, but with the addition of pre-cancellation Doppler filtering to enhance clutter suppression, (3) a Sum-Difference-Auxiliary architecture and pre-cancellation Doppler filtering but with the addition of frequency subbanding to extend performance for wideband operation, and (4) an interference suppression option for very wideband stretch processing receivers. Our demonstration plan includes an experimental system including a phased array radar as part of a comprehensive Phase I and Phase II program, eventually leading to implementation of jamming suppression processors for retrofit into existing Navy radars.The technology developed can become an integral part of many future radar system designs for both military and commercial applications. A variety of applications for shipboard, airborne, spaceborne and ground based passive receive systems can significantly benefit as well. Commercial applications for communications systems will also benefit from this technology development.

Title:Interference Suppression Techniques Development for Future Combat Scenarios
Abstract:The complex jamming threat to Navy radars, such as the AN/SPY-1 radar family, consists of barrage and modulated noise jammers on the one hand, and analog and digital deceptive jammers on the other. Vulnerability to jamming will generally increase with growing radar sensitivity and the evolving Digital Radio Frequency Memory (DRFM) based deceptive jammer technology and its broad proliferation. This proposal is concerned with waveform and processing techniques to enable existing radar systems to maintain their operational performance in the presence of deceptive jammers. (Unlike techniques required to counter noise jammers, the above do not require changes to array beamforming architecture and receiver design.) In the proposal, we first discuss fundamental repeater jammer limitations. We then describe several potential techniques to counter repeater jammers, whose respective enabling technologies are deemed to exist. They are separated into several processing categories, and include both passive and active approaches. Several techniques are selected for study during the basic Phase I period, and a simulation package is proposed to be defined in the Phase I Option and developed in Phase II, along with validation tests, in support of off-line analysis and inclusion in radar upgrades.This research and development effort could lead to clear understanding of fundamental repeater jammer limitations - particularly of the DRFM variety - and of techniques to counter such threats both in existing radar systems, through upgrades, and in future radars. A simulation package to be developed in Phase II of this SBIR will support the insertions of such techniques to various radar systems - future and existing. The products of this effort are expected to be applicable to all military radars within the context of shipboard, airborne and space-borne applications.

Title:Dynamic Sensor/Weapon Alignment Algorithms
Abstract:Development of concepts and associated algorithms for dynamic alignment of ship sensors and weapon systems is proposed. Correlation processing of ship sensor data provides the opportunity to develop composite tracks and calculate the difference or track offsets in the constituent sensor tracks that are each based on single sensor measurements. Both the short and long-term time averages of track offsets of correlated sensor tracks from different sensors are useful data for sensor/weapon alignment. The sensor misalignment, regardless of the cause, would be dynamically available on a track-by-track basis by extracting the track offsets measured in the track correlation process. The proposed alignment algorithm development would address misalignments caused by a multiplicity of conditions such as ship's flexure, temperature differentials and navigation sensor latency. The technique would also address sensor misalignment caused by the effects that refraction and ducting have on microwave propagation by sensors operating at different wavelengths. DSR proposes an alignment algorithm integrated into a COTS based multi-source data fusion architecture. This architecture supports an innovative data processing technique that leverages correlated platform-centric sensor tracks to form a platform-centric dynamic sensor alignment algorithm. The algorithms would be inserted into legacy and/or developmental multiple-source data fusion processing architectures.The sensor-to-sensor/weapon alignment algorithm is envisioned as a processing module suitable for other surveillance requirements including law enforcement, air traffic control, drug interdiction, ship multi-radar based navigation and collision avoidance and commercial vehicle location and tracking.

Title:Dynamic Sensor/Weapon Alignment Algorithms
Abstract:Electronic Support Measures and infrared sensors for the next generation US Navy surface ships will have considerably tighter angular accuracy than today's systems such as the Advanced Integrated Electronics Warfare System. The improvement in accuracy is motivated by factors such as: requirements to support track correlation to other combat systems sensors, de-interleaving closely space emitters, and cueing combat system fire control and multifunction radars such as the AEGIS AN/SPY-1D. The objective of the Phase I effort is to determine the feasibility of dynamic alignment methodology that can be utilized between the ship sensor systems and weapons systems. This will be done through ship structural bending analysis and covariance analysis for various inertial attitude reference systems including GPS phase measurements. Innovative candidate Automatic & Dynamic Alignment System (ADAS) approaches will be analyzed evaluated for cost, cueing sensor bias accuracy, time latency, and platform-independence. Phase II will involve ADAS prototype development, HWIL & SWIL testing, as well as at sea testing.The anticipated modularity and compatibility of ADAS should attract users in the commercial market who have a need for multi-device alignment such as commercial aircraft, ships, land vehicles, air traffic control, and oil explorations.

Title:Advanced Personal Communicator (APC)
Abstract:As the complexity of the battlespace has grown exponentially and the outcome of the engagement is increasingly a function of communications speed, accuracy and relevance, it is critical to have a always-connected ship-board personal communications system that has the ability to support information-in-place which receives and transmits location and context intelligent information, supports decision processes and disseminates orders for action in near real-time. Inter and intra team coordination requires ubiquitous and interoperable communications to support the tremendous demands being placed on disparate and dispersed groups whether at the individual, specialized or ad-hoc group, division, ship, or higher level. This proposal addresses the development of a smart, self-organizing, ad-hoc connectivity-aware wireless network that will enable the essential communications connectivity between and among these discrete requirements. Because all communication demands are not the same, a suite of interoperable wireless devices must be employed to provide location and context intelligent voice, data, and multimedia communications. This concept will be critical to achieving an Advanced Personal System. Additionally, it is imperative to implement a technology to provide a security level that provides a low probability threshold for detection and will support multilevel access protections that prioritizes bandwidth.A successful approach will result in a blueprint for development of a robust, and fault tolerant ubiquitous and ad-hoc wireless network that provides location and context intelligent voice, data and multi-media communications that will serve as a high-reliability wireless extension of existing networks. It is expected to have wide application in areas such as DOD operational forces, inter and intra ship communications, hospitals, emergency response centers, nuclear plants, mobile and remote workers, and any high value industrial asset or process.

Abstract:The goal of the project is to develop an innovative and cost effective technology, that makes the local Common Tactical Picture (CTP) available to warfighters in all echelon theaters through a hands free heads-up display and Windows based computer system. Voice recognition software and touch screen software will serve as the main input devices. By collecting, plotting and updating all warfighter's GPS coordinates, the Common Tactical Picture's Friendly Overlay is updated in real time as echelon shifts take place in the battlefield. Video capturing capabilities aid in providing an integrated tactical picture to all warfighters through virtual data exchange capabilities between Global Command and Control System (GCCS) main CTP who serves as server and Advanced Personal Communicators acting as clients. This relationship will maintain every warfighter's CTP updated. Physiography, political and mission specific feature overlays are generated from Global Command and Control System (GCCS) data sets. Phase I develops the system architecture and demonstrates the feasibility of the proposed techniques. Phase II builds and delivers an engineering prototype system to the Navy.The proposed Low Cost Advanced Personnel Communicator has great potential for use by all branches of the military and real-time information exchange businesses. It provides accurate, updated information, creates a common tactical map and makes mission specific information available when such information is imperative.

Title:Advanced Personal Communicator (APC)
Abstract:Communication is paramount in nearly all military operations, ranging from tactical operations to the efficient maintenance of equipment. On the battlefront, warfighters are constantly in need of updated information describing the battle zone. To support these warfighters, maintenance personnel need access to a myriad of technical documents and schematics instantly and conveniently. Since maintenance takes place in the field, the maintenance engineer requires display technology that can give him the information he needs in very tight spaces, without causing eyestrain or discomfort. Especially important is a communication device which accesses a central database of information, and that leaves the user's hands free to accomplish other tasks at hand. A device is needed which addresses all of these problems in whole. We propose a system that utilizes modularity to approach the variety of challenges. Modules would consist of display units, input devices, and virtual tools. All would be wireless and interfaced through a Personal Computing Unit, (PCU) which could be worn about the waist, leaving the operative with both hands free.This technology has commercial applications in the areas of flight maintenance and field maintenance. It would also be useful for search and rescue teams, and hazardous waste monitoring and cleanup systems.

Title:Model Checking UML Designs
Abstract:Real-time embedded systems are becoming increasingly complex and safety critical. In order to satisfy the complexity and safety requirements developers need tools and methodologies that support rigorous and complete specification capabilities, robust automated translation from design to implementation, support for debugging of the designs at the semantic level of the design specification language, and sophisticated verification and analysis of design models. The Unified Modeling Language and the current generation of COTS tools meet many of these requirements, however they are woefully inadequate in the area of verification and analysis. We plan to augment best-of-breed COTS tools with model checking capabilities. This will not only allow developers to verify their designs, but to also extract greater value from the functionality provided by COTS tools. We propose to integrate model checking with a UML design environment, develop techniques for ensuring scalability and precision, develop a system that allows both everyday and expert users to easily specify properties for verification and develop a system for providing users with insightful counterexamples when their specified properties do not hold.The proposed system will be of use in the design and development of embedded systems. This system will allow companies to develop highly reliable embedded real-time systems.

Title:TimeFrame: A Framework for modeling, analysis, and realization of reliable, object oriented real-time systems
Abstract:We propose to investigate and prototype an integrated Framework called TimeFrameTM, which shall integrate the modeling, analysis and realization (code generation) of performance critical, reliable, object oriented systems. TimeFrame will utilize UML stereotypes and tagged values and allow modeling of components and interfaces augmented with real-time and reliability specifications. A catalogue facility will enable COTS and custom components/classes to be reused consistently. Using these models, users can generate code targeted towards a standard library, also part of the Framework. The library will consist of (i) standards-based messaging primitives, (ii) distributed resource sets for guaranteed and bounded performance and (iii) interfaces that enable dynamic reconfiguration and active redundant components. Both the code generation and library will be designed for popular languages and platforms thereby supporting a wide variety of projects. In addition, through tight integration with TimeWiz, users will be able to perform performance analysis and generate analysis reports characterizing the ability of the system to meet its deadlines. TimeFrame will also allow specification of custom analysis algorithms of the model to aggregate and extract other reliability and performance aspects. Integration with TimeTrace, TimeQoS and TimeStorm will provide both high-level and low-level debugging and profiling support for the Framework. TimeFrame will be scalable to support a large number of components and provide a visual, hierarchical organization facility.In U.S. defense systems, fly-by-wire avionics, process control, nuclear power control, automated manufacturing, air traffic control and medical systems, life-threatening situations can arise if failures occur due to the misuse of reusable object-oriented software. The TimeFrame framework will maintain, model and analyze the timing and reliability properties of software components and enable the disciplined development and reuse of object-oriented components in the design of such systems.

Title:Main Beam Jamming Nulling in Phased Array Radars
Abstract:A need exists to simultaneously mitigate/cancel interference due to sidelobe and mainlobe jamming and clutter. Practical signal processing techniques with application to existing radars (such as the SPY-1) are required. In this proposal ISL addresses this need by examining two approaches. 1) the use of spatial-only adaptive array processing (followed by Doppler or MTI processing) and 2) space-time adaptive processing (STAP). Each technique will be enhanced by the delta-delta channel, which is currently available but unused on the SPY-1 radar. ISL will explore past related efforts to examine both the spatial and STAP techniques, and compare these techniques in terms of performance and cost/risk of implementation. The spatial-only techniques offer the potential for low-cost, low-risk implementations, however are limited by the number of jammers that can be simultaneously mitigated. STAP offers the potential to simultaneously mitigate a larger numbers of jammers at the cost of increased computational requirements. ISL's site specific radar simulation capabilities will be used extensively in the algorithm development and evaluation.The proposed work will benefit many DoD users requiring advanced interference mitigation technology/algorithms. All shipboard and theater/battlefield array radars (e.g., SPY-1, TPS-59, TPS-70, Patriot, and THAAD) can potentially benefit from this technology as a result of improved robustness to interference and improved target resolution.

The primary emphasis is: (1) to address phased array radars that do not have access to their subarrays, i.e., only traditional sum, difference, and auxiliary channel availability is assumed, (2) to design an architecture that will effectively suppress simultaneous sidelobe and mainlobe jamming, and (3) to investigate techniques for making the adaptive algorithms compatible with high level, high duty cycle clutter returns in the main beam, as may be expected in the littoral operating environment. Two innovative and promising architectures will be examined: (a) a sequential constrained multiple sidelobe canceler (MSLC)/mainlobe canceler architecture combined with a variant of the Maximum Likelihood Beamspace Processor (MLBP), and (b) a modified MSLC-MLBP adaptation, employing a constrained MSLC and a reduced channel adaptation of the MLBP.

Title:New Non-Cooperative Target Recognition (NCTR) Techniques Development
Abstract:Scientific Systems Co., Inc. (SSCI) and its subcontractor Lockheed Martin Naval Electronics & Surveillance Systems (LM-NESS) propose to develop an advance simulation framework for High Range Resolution Radar (HRRR) joint target identification and tracking. New techniques for target identification based on HRRR returns, also known as target ``signatures'', will be implemented in this advance simulator. Depending on the illumination angle, different scattering centers on the target are excited, and consequently, the `shape' of the target signature change based on these angles. Therefore, a coupled tracking/identification algorithm should be used in this situation in order to identify a target along an unknown trajectory. Target identification based on HRRR signatures has proven to be a difficult task, due, in part, to the high variability of the signature shape. Signature shape can change dramatically with the aircraft pose angle, and also with the aircraft configuration (addition or change in external ammunition like missiles and bombs). An advance simulation toolbox is needed to evaluate the performance of different identification techniques. The toolbox will include an HRRR simulation, that will allow to model different type of aircrafts, and also to modify the radar parameters (waveform, Signal to Noise Ratio (SNR), and Pulse Repetition Frequency (PRF)). For this effort, SSCI has teamed up with Lockheed-Martin Naval Electronics & Surveillance Systems (LM-NESS), Eagan, MN., who will provide technical support for this effort. Non-cooperative Target Recognition (NCTR) algorithms has a vast field of applications throughout the Navy, including Tactical Ballistic Missile Defense, Ship Self Defense, and Ship Area Defense. Also the Air Force is a potential costumer for this technology. Commercial application of this technology exist in several areas such as: medical screening and diagnosis, remote sensing, road and bridge inspection, and buried waste detection.

Title:New Non-Cooperative Target Recognition (NCTR) Techniques Development
Abstract:To evolve High Range Resolution based NCTR algorithms for application to shipboard TBMD, Self Defense, and Area Defense missions, the Navy surface radar community needs a comprehensive tool that combines detailed target, propagation, and environment models with a flexible coherent radar model. RF signature models, such as Xpatch, can compute the complex frequency, polarization, and aspect angle RCS dependence of targets. Current NCTR development generally involves application of candidate NCTR algorithms against idealized radar signal returns calculated from RCS profiles generated by such models. The limitation of this approach is that it does not account for deviations from an idealized signal return, due to radar errors, propagation effects, and natural and man-made interference. Consequently, their effects must later be evaluated through expensive, yet limited, live target testing. TSC proposes to develop a tool that combines detailed radar and environmental models with complex backscatter modeling. It will integrate TSC's Signal Environment Simulation (SENS) - an existing comprehensive coherent radar model - with existing signature models such as Xpatch, and a six degrees of freedom target trajectory model. This tool will provide effective support for Navy NCTR algorithm development efforts, as well as for predictive or post-test analysis of live target testing.This research and development effort could lead to a unified NCTR development tool capable of modeling all effects from waveform generation and transmission through propagation reflection from the target and reception and signal processing. Such a tool provides a unique capability for design and development of NCTR methods and algorithms, as well as a much needed predictive analysis capability for NAVY testing.

Title:New Non-Cooperative Target Recognition (NCTR) Techniques Development
Abstract:Toyon Research proposes to develop a non-cooperative target recognition (NCTR) module that classifies airborne targets based on high-range-resolution (HRR) radar measurements collected by any number of sensors over time. The NCTR module will consist of a classifier that uses a representation of the target density function at a number of different aspect angles coupled with a fusion module that can fuse multiple measurements collected over time. The fusion module will consist of a Bayesian Network that updates beliefs about what type of target is being measured by taking into consideration a priori information regarding the types of airborne objects in an area and the capabilities of the sensors providing measurements. Additionally, the network will consider the degree to which a particular measurement matches the expected signal of each type of target of interest. We propose to develop an initial version of the NCTR module and provide a demonstration of its capabilities on an example problem during Phase I.The successful completion of this research will result in the development of an NCTR module that can classify airborne objects using multiple radar measurements collected over time. Non-military applications of this technology include air traffic control, counter-drug operations, and medical diagnostics.

Title:Electrostatic Discharge Analysis of Reactive Material Formulations
Abstract:Safety assessments of current and future energetic materials require a range of tests, one of which is the determination of the electrostatic discharge (ESD) sensitivity to ignition and propagation. There is currently no standard for circuit design, spark energy, sample size/configuration or determination of a successful test. The need exists for a standard ESD testing machine and related testing methodology to allow accurate and reproducible ESD measurements of energetic materials. The methodology should account for all credible ESD spark sources, such as humans, charged metallic objects (tools) and charged energetic material. In addition to standardizing the ESD machine and methodology, an improved method of determining the energetic materials behavior after an ESD event is required. The proposed detection system is based on an optical method which provides accurate recording of the events leading to material ignition. Both visible and infrared "signatures" emanating from spark to ignition to propagation are recorded in a non-subjective manner. Removal of the human observer, along with the use of a standard detector, will allow for more accurate and reproducible ESD characterization. Upon successful completion of this project, a new testing methodology will have been developed for characterizing an energetic material's electrostatic discharge sensitivity. The new test methodology will be used to design and develop affordable new ESD test equipment to allow accurate, reproducible characterization of an energetic materials' sensitivity to ESD, as well as providing the capability for ESD signature recording for future comparisons. This capability will serve the military as well as the commercial sectors where many accidents can be prevented by more accurate assessments of the ESD sensitivity of reactive materials.

Title:Electrostatic Discharge Analysis of Reactive Material Formulations
Abstract:Electrostatic discharge (ESD) sensitivity is critical to understand the safety of energetic materials. ESD ignition of CHNO materials is discernable by a flash, smoke, or audible report. For a small class of reactive materials, e.g., metals and metalloids or metals and binders, the current ESD test methodology is insufficient. TPL proposes to develop an integrated post-dischrge/ESD ignition threshold apparatus. The appartus will determine the extent of the reaction via an analytical technique. These data will be subjected to statistical procedures which will provide insight into the ESD sensitivity and provide applicable data for safety assessment. Candidate materials will be selected and theoretical predictions of the ESD-reacted products will be made. The effects of sample environment will be nulled or baselined as necessary. At least five different analytical techniques will be evaluated for determining the extent of reaction from ESD. An analysis technique will be selected and refined for this application. A preliminary design will be developed. TPL has the resources and the experience to conduct a successful program. The company has outstanding in-house laboratory facilities with machine shop capabilities for prototype or test fixture fabrication. Personnel are familiar with reactive materials, storage, and shipping.The successful completion of this program will provide the Navy with a quantitative method of determining the ESD sensitivity of reactive materials. Better estimates of safety can be made and risk mitigation of hazards will be more accurately determined.

Title:A Software Based Navigation Agent (NavAgent) Tool for Navigation Systems Integration
Abstract:This project develops an innovative navigation agent software tool, integrated with standards based information management platform, that would simplify the task of NavInfo integration with shipboard navigation and weapons systems networks and that would significant reduce the cost of managing these systems. The tool would allow the definition of Navigation Agents (NavAgents) that would adapt the information needs of a new system into an existing infrastructure. The NavAgents could be defined either by a system itself or by an administrator through a network management console. This allows maximum flexibility while not necessarily requiring that the new system support NavAgents directly. Each NavAgent could be defined for selective processing and mixing of the any NavInfo being integrated. The NavAgent on the network management console would serve as a very powerful tool for solving interfacing problems during installation and integration as well for normal ship's maintenance. The activities of NavAgents could be trapped to a file for later analysis or playback. This allows the interfacing problems to be easily isolated, diagnosed, and resolved.The proposed navigation agent software tool has great potential applications for military and commercial aircraft, space vehicles and ships. It provides reliable, robust, and convenient navigation integration tool.

Title:A Navigation Agent (NavAgent) Tool for Shipboard Navigation & Weapons Systems Integration
Abstract:Through the years, the Navy has seen advances in navigation technology flow through their tactical navigation systems. These include the AN/WSN-5, AN/WSN-7, NAVSSI, and GPS. With each navigation system enhancement came more accurate, precise, and complete navigation information at higher and higher data rates, culminating in today's ability to maintain high accuracy (even in jamming), provide for a single shipwide navigation solution, utilize and synthesize multiple navigational sub-systems, and, provide operational availability in excess of 99%. However, the engineering efforts that have been performed and applied within the navigation problem domain, have not been applied when addressing how the entire navigation system might provide its information to those "other systems" requiring it. The Navy is still using point-to-point interfaces and outdated MIL-STDs, which almost never document "those unique intricacies" of how information data interchange really work. Using current technologies that include HTTP, eXtensible Markup Language (XML), and Simple Object Access Protocol (SOAP), Synetics proposes to establish a Computer Aided Agent Development and Execution Environment (CAADEE) from which Information Interchange Agents (IIAs) can be constructed, configured, spawned, monitored, and controlled. The IIAs would be capable of attaching themselves to the specific systems and handling their data interchange needs.Although CAADEE would be initially targeted to support the needs of the navigation problem domain, its design would be capable of supporting the configuration, construction, spawning, monitoring, and controlling of IIAs for other problem domains. This capability allows CAADEE and its IIAs to be applied to a myriad of DoD system and system-of-system engineering and development efforts. The commercial market space has similar needs regarding information interchange. For instance, the business commerce community is pushing Business-to-Business e-commerce, which is nothing more than the exchange of data between businesses. CAADEE and its IIAs could meet this need as well.

Title:Environmentally Adaptive Radar
Abstract:This proposal describes a plan to develop radar systems which will adapt the radar parameters in order to optimize the performance under different environmental conditions. Environmental data will be collected from various sensors including those available from the radar echoes. These data will first be used to create as complete a picture of the environment as possible. Next, the radar parameters will be selected based on the optimum conditions under these environments. An expert system will be developed to synthesize the environmental conditions and to predict the radar parameters. Design, development and demonstration of the expert system is the major task during Phase I. Extensive simulations will be performed in order to develop the expert system and for demonstration of the improvements of the radar performance using the expert system. Detailed development and demonstration using real data available from radars will be performed during Phase II. Adaptive radars will improve the performance of a variety of military and non-military radars and will have widespread applications as add-ons to existing radar systems.

Title:Utilization of Atmospheric Refractivity Information to Improve Radar Operation in Littoral Environments
Abstract:Atmospheric refractivity conditions have significant influence over radio frequency (RF) propagation in the Earth's troposphere. Refractivity conditions can vary from sub-refraction to strong-trapping, thereby altering radar detection, measurement, and clutter performance across its coverage volume. Current Navy radar systems operate without regard to changing refractivity conditions, mainly because quantitative descriptions of such conditions have not been generally available to operational systems and could not be converted to their propagation performance equivalent in near-real-time. Recent advances in the areas of refractivity estimation from basic parameter measurements and from clutter measurements, coupled with improvements in the processing efficiency of Parabolic-Equation-based propagation models, can narrow that gap. This proposal identifies applications for ship-based radars, such as the AN/SPY-1 family, whose performance could be enhanced through judicious utilization of refractivity information. It describes architecture and techniques to combine information from linear, high-resolution, clutter-maps, with information from propagation-coverage-maps, to improve radar performance in detection, tracking, engagement, and resource conservation, and to further extend the utilization of such information to improve radar sensor fusion and combat system performance. Specific techniques to be analyzed in detail during the Phase I base-period in order to establish their feasibility are described - each with its corresponding technical approach.This research and development effort could lead to clear understanding of shipboard sensor applications whose performance could be enhanced via judicious use of combined propagation and clutter information, and of the processing architecture and processing algorithms required to support such improvements. It could be used to enhance the performance of new fleet sensors and combat systems via appropriate design, and of legacy systems through upgrades. A proposed software analysis package, which will contain pertinent architectural elements, will be marketed to potential radar and radar upgrade developers, in support of specific algorithm developments.

Title:Mission Planning for Tactical Shipboard EW Systems
Abstract:DSR proposes development of a methodology for the utilization of information from mission objectives and a wide variety of platform, sensor and intelligence databases to effectively adapt tactical shipboard sensor resources to a dynamically changing tactical environment and to increase the time available to develop appropriate responses to changes in the tactical environment.The overall objective of the proposed research is for Digital System Resources, working closely with Navy fleet representatives, to establish and validate a baseline understanding of the current Navy EW mission planning concept of operations, associated requirements, data sources dependencies, and existing system capabilities. The result of this research is intended to form the basis for successful execution of development and production of an EW mission planning component applicable to both current and future Electronic Warfare Systems. Specifically, the results will identify methods to allow the user to visualize the anticipated environment and allow for adaptation of system resources based on the intelligence gathered.Provide mission planning requirements and prototype mission planning displays. The Phase II plan will specifically target integrating the approach into a state-of-the-art system for demonstration. Potential commercial applications for situation awareness visualization techniques, integrated database analysis tools and tools that allow the user to develop rules to optimize system resources.

Title:MainTrain: Maintenance Skills Training Through Distributed Learning Principles
Abstract:Maintenance and technical skills training is required to build individual proficiency within the U.S. Navy battle groups as well as many of the independent operating units. However, force reduction and budget cutbacks have resulted in the transfer of training responsibility for battle groups to the large deck ship and battle force commanders. With further reductions in force levels and budget on the horizon, the Navy has to turn to harnessing distributed learning principles, remote maintenance skills training, and maintenance support in a web-based delivery environment. Phase I of this effort will create the system concept and design documents for a web-enabled interactive mentoring system and an instructional content sharing and management system, the two core components of MainTrain, a web-based maintenance instructional delivery and troubleshooting support system.NAVSEA O4L will directly benefit from this technology by having a maintenance crew cost-effectively trained despite force reduction and budgetary cuts. The commercial version of this system will offer cost-effective, realtime assistance to maintenance field personnel engaged in equipment and machinery repair in remote field locations. The avoidance of travel costs and satisfying time-criticality requirements are key to acceptance of this solution in the commercial world.

Title:A Tool for Risk-Based Maintenance and Inspection of the LPD 17
Abstract:Risk-based methods for inspection and maintenance can significantly reduce lifecycle cost by basing inspection and repair intervals on the risk of incurring damage rather than on arbitrary periods. Not only can the methods reduce inspection cost and downtime, they can actually increase ship reliability and safety by defining explicit failure probabilities for all important components and functions. SoHaR and its subcontractor, EQE/ABS (a part of the American Bureau of Shipping), propose to develop a Risk Based Maintenance Strategy Tool (RBMST) to support a risk-based maintenance approach for the LPD 17. The innovations of our approach include the use of a probabilistic fracture mechanics model as opposed to the traditional SN curves. The benefit of a probabilistic model is that it yields a failure probability rather than an expected life. The RBMST will also integrate corrosion and fracture fatigue mechanisms in a single model, account for previous repair history, and incorporate cost and safety. The model uses a conditional probability approach to account for past maintenance and repair actions. A prototype tool using the Matlab program will be delivered at the end of Phase I. The prototype will include sophisticated modeling capabilities, results plotting, and a graphical user interface. The team members combine a unique combination of expertise in probabilistic methods and domain expertise in marine and ship structures that will ensure project success.Risk based maintenance is becoming increasingly important in all aspects of the marine and offshore technology industries. The benefits relative to fixed periodic maintenance programs are lower downtime and decreased inspection costs. The probabilistic fracture mechanics approach that is being used in the RBMST provides a significant advantage over the traditional engineering "design rule" approach that is based on SN curves and predicted life. RBMST permits a comprehensive and detailed risk-based maintenance and inspection approach to be implemented. In its full implementation RBMST will be able to calculate all static and dynamic loads, predict condition into the future based on the probabilistic techniques, and provide a visual representation of the results.

Title:Ultra Wideband Active Acoustic Conformal Array Module
Abstract:An ultra wideband conformal array module will be developed and designed for use on submarines. The band of interest is 10 to 85 kHz with a 450 steering capability without grating lobe structure. A power density of 11 watts/cm2 over the frequency band is desired. The goal is to include the transducer elements, T/R switch, power amplifiers and receive preamplifiers in the module. We consider the ultra wideband transducer with steering requirements to be the most challenging aspect and the one which requires advance innovative concepts for a practical solution. We propose to consider the use of high power density materials to obtain the output, a multiple resonant system to obtain the bandwidth and a multiple actuated piston head to obtain the desired steering even at the highest frequencies, along with array stability at the lowest frequencies. The transducers would be made as small as practical to allow the packaging of the electronics within the module. Extensive circuit analysis, array analysis and finite element modeling would be used to optimize the design.An ultra wideband steerable transducer module will be designed for submarine applications. The multi-resonant, multi-actuated piston design chosen should provide an approach applicable to current and future underwater acoustic systems. The technology should provide a significant improvement for high frequency sonar systems, and possibly for oceanographic and ultrasonic imaging systems.

Title:Wideband Conformal Transducer Array Module
Abstract:MSI proposes the development of a sonar array module that has a very wide bandwidth and can support a range of array configurations including conforming to a curved hull structure. The MSI design will be built around piezoelectric ceramic/polymer composite, a proven transducer material with inherent advantages that is finding ever-wider application in broad band sonar systems. The transmit array will be electronically beam steerable. Outboard receive signal processing, muxing, and telemetry electronics will be integrated within the array module along with drive electronics for the transmit array, so that the only hull penetration requirements will be for DC power and data telemetry. In Phase I, MSI will conduct a design study to determine the feasibility of making an affordable modular conformal projector array that meets functionality specifications for the intended Navy application. In Phase II, MSI will perform build and test prototype array iterations and demonstrate that the final design meets performance, cost, environmental and configuration requirements for Navy use. In Phase III, MSI will establish a business relationship with appropriate platform and sonar systems integration contractors to transition the modules to production and will then produce the modules to meet Navy deployment requirements The proposed program will enable the navy to meet a specific platform sonar requirement. The technology developed during the program will have applicability to all Navy and commercial platforms, both surface and subsurface, that operate in the RFP specified frequency ranges. This includes defense and commercial markets in which MSI already participates as a transducer array vendor.

Title:Underwater Velocity Indicator
Abstract:The Navy has a need for an Underwater Velocity Indicator which can be mounted on a submersible platform and which can measure the three-component velocity of the platform relative to the water at speeds up to 40 kts. The Acoustic Doppler Current Profiler (ADCP) can provide this capability. These instruments can measure the three-component velocity vector of the water relative to the platform on which they are mounted at a sequence of ranges from the transducer face. This well established acoustic technology is the most reliable and robust way of meeting the Navy's requirement for a compact saltwater velocity indicator system which can be calibrated and mounted easily on a submersible platform. Present ADCPs, however, are limited to speeds lower than 40 kts. by their processing capabilities and their physical configurations. Phase I will consist of reviewing the Navy's requirements and adapting an ADCP to meet them. We will consider both conventional and phased array transducers as well as existing and developmental electronic implementations of this new, High Speed Underwater Velocity Indicator. We will provide a prototype instrument for testing by the Navy in Phase I.The High Speed Underwater Velocity Indicator will extend the use of ADCPs to high speed platforms, both military and commercial. This includes undersea vehicles and surface vessels such as patrol craft and ferries. It will also find application in industrial facilities requiring cost effective flow measurement data.

Title:Accurate, Large Bandwidth Underwater Speed and Flow-Angularity Measurement Device
Abstract:A miniaturized, low power and low-volume instrumentation system using waterproofed micro-thin hot-film sensors and large bandwidth constant voltage anemometer will be developed for accurate measurement of speed and direction of underwater vehicles. The performance of the proposed innovation will be unaffected by changes in ambient temperatures, depth, and salinity. Sensors will be waterproofed to protect them from corrosive effects of marine environment. The device will have a large built-in redundancy and the design will permit a relatively straightforward handling of biofouling. The proposed innovation is based on flow characteristics and thereby eliminates inherent disadvantages present in conventional techniques based on fluid properties. The proposed innovation will be practically immune to EMI, RFI, and drift. Both the probe and the electronic instrumentation system will be amenable to miniaturization. The weight of the sensor will be negligible while the instrumentation weight will be reduced to a few grams with the use of flexible circuits, with corresponding decrease in power requirements. In Phase I effort, a number of probe-design configurations will be tested in Tao Systems' high-speed water tunnel to demonstrate the feasibility, accuracy and repeatability of the innovation. Velocity indicator can be used for commercial marine vehicles or in industrial facilities requiring cost-effective flow measurement data.

Title:All Optical Towed Array Position Measurement System
Abstract:Physical Sciences Inc.(PSI) proposes to develop a fiber optic position measurement system for multi-line towed array applications. PSI's proprietary approach for fiber optic position measurement system sources and receivers will meet the requirements of the solicitation each with a very compact package size, nominally 0.5 inch diameter and no longer than 5 inches. George Connolly, MTI, will assist PSI, validating PMS source requirements and then PSI will complete the design of proof of principle configurations for at least two different concepts. These proof of concept designs will be initially tested in the laboratory and then at NUWC's Dodge Pond demonstrating proof of principle operation and that the requirements can be met by PSI's innovative approach. A Phase II program plan will be developed that when performed in a Phase II program, will result in a complete demonstration of the key technologies and components of the fiber optic position measurement system necessary for prototype development. The Phase I Option would be the detailed design of the Phase II system.The proposed program will develop a fiber optic position measurement system, which is an enabling technology for all-optical towed arrays. Such arrays for both DoD and commercial applications, e.g., seismic oil exploration, have the potential of reduced costs, increased reliability, and improved performance.

Title:Application of NDE Techniques for In-Situ Inspection of Submarine Propellor Shafts
Abstract:Although no one technology solves all the inspection issues peculiar to submarine propeller shafts, a combination of long range ultrasonic techniques succeed where single approaches fail. One method we will use emits a pulse of refracted shear waves that interact with indications in the material, causing a signal to be reflected back to the transducer. Another method generates refracted broad beam longitudinal waves that diffract off discontinuities resulting in a signal that is detected by a second, discrete receiver. Experiments using a calibrated defect specimen will demonstrate that these two methods can detect deep flaws and surface corrosion in the base material, pitting in the FRP wrap, and discontinuities in the bond. Fixtures for the transducers allowing for inspection of the curved propeller shaft and a data reduction algorithm that removes much of ambiguous noise that stymie other techniques, will be key features of our approach. Our program will produce a conceptual design for a deployable prototype system for fabrication and test in Phase II. Foster-Miller has teamed with the world's premier submarine builder, and an internationally recognized NDE development firm to present the best in submarine technology, materials and NDE knowledge, and implementation and integration skill available anywhere. (P-01383) The combination a variety of long range ultrasonic techniques succeed in detecting corrosion and wear indications on propeller shafts where single approaches fail. Early detection of these flaws stand to save the Navy millions of dollars in direct propeller shaft inspection and nuclear asset utilization over the course of just a few years. The technology is directly applicable to other Navy ships and commercial fleets as well. Off the shelf technology will be used extensively to ensure that additional systems will be inexpensive to procure in the event that the technology is implemented fleet wide.

Title:Propulsion Shaft Interrogation
Abstract:The Navy currently employs a time-based maintenance schedule for its submarine propulsion shafts, in which every 6 or 10 years each shaft aboard the submarine is removed from service, stripped of its protective FRP layer, and inspected for cracks and wall-thinning with magnetic particle and liquid penetrant inspection methods. This represents an expensive investment of time, money and effort on the part of the Navy, but is currently the only proven method of maintaining the readiness of the fleet. TRI/Austin proposes that the Navy shift focus to a condition-based maintenance schedule through funding a research and development effort to build a multi-diameter in-line ultrasonic inspection tool that inspects the propulsion shaft by removing the propeller and inspecting from the inside. This approach allows the tool to inspect the shaft regardless of whether it is in F-, M-, or A-Condition. The TRI/Austin team's experience in developing commercial multi-diameter in-line inspection tools, coupled with our triple-redundancy inspection system design, assures complete and total inspection of the entire propulsion shaft and represents a tremendous opportunity in terms of reducing the Navy's cost of ownership and operation of the submarine fleet.Propulsion shafts find widespread use throughout all the vessels in the U.S. Naval fleets, those of her allies, and commercial marine vessels. Our innovative tool design can save millions of dollars world-wide through its adaptation to other propulsion shaft designs. We also anticipate a strong response for a multi-diameter in-line tool in the oil and gas industry, nuclear reactor piping in which the pipes are typically thick-walled, and potentially through the inspection of terrestrial drive shafts. Our aggressive technology transfer work is designed to target these and other opportunities towards full commercial development.
