The Air Force Research Laboratory (AFRL), Military Satellite Communication (MILSATCOM), and National Aeronautics and Space Administration (NASA) have a current and future need for advanced commercially available inherently radhard primitive cell libraries to support new designs for satellites and other spacecraft. American Semiconductor Inc. proposes the use of double gated Flexfet technology for ...

INADEQUATE STARTER FEEDS SEVERELY HOLD BACK NEW AQUACULTURE ENTERPRISES SUCH AS PRESENT ATTEMPTS TO RAISE FISHES WHOSE LARVAE DEVELOP FROM SMALL EGGS AND HAVE VERY "DIFFICULT" FOOD REQUIREMENTS. INERT LARVAL FEEDS HAVE NOT SUCCESSFULLYELIMINATED THE STRICT DEPENDENCY ON NATURAL FORAGE DURING THE CRITICAL POST-LARVAL STAGE AFTER YOLK ABSORPTION AND BEFORE THE DEVELOPMENT OF A DIGESTIVE SYSTEM WITH ...

Manning Applied Technology proposes to develop a handheld infrared spectrometer, ideally suited to detection of airborne chemical agents at and below permissible exposure limits. This approach offers unmatched sensitivity and specificity for detection of all types of chemical vapors. The instrument is modular, rugged, compact and highly sensitive. Volume pricing will be less than $1000 each. ...

We investigate the development of a secure fuselet runtime environment built on a foundation of aspect-oriented web services. Aspect-oriented techniques enable the modularization of crosscutting concerns such as remote access, security, and monitoring using code instrumentation. We compose aspect-oriented instrumentation with web service technologies in a noninvasive and orthogonal manner, and lev ...

Bearing failure in satellite applications is related to lubricant starvation rather than fatigue, and health monitoring systems for these applications must be able to observe subtle changes related to lubrication state. Phase I included an experimental study to identify candidate monitoring approaches, and the data collected confirmed that cage motion characteristics and instability are highly sen ...

Hanger bearing failures occur unexpectedly and have resulted in loss of aircraft and life in both military and civilian rotorcraft. New Health and Usage Monitoring Systems (HUMS) that are currently being demonstrated on the UH-60 include sensing capabilities that offer the potential to diagnose and predict hanger bearing problems with sufficient lead time to prevent catastrophic failure. However, ...

During Phase I, the Blackhawk hanger bearing and oil cooler fan bearing applications were studied in detail, including analysis of vibration and temperature data from used oil cooler bench tests (conducted by Sikorsky) and used hanger bearing bench tests (conducted by Sentient). This data, along with an analysis of operational and environmental conditions, has allowed us to identify the probable r ...

Development of accurate and effective new diagnostic and prognostic capabilities for JSF PHM will require extensive data on both health and faulted systems states. While healthy signatures can be collected quickly and easily, faulted systems are only observed rarely, and duplicating faulted conditions with seeded fault tests is time-consuming and expensive. Simulation models for faulted conditions ...

Modern turbine engine lifing approaches compute damage accumulation in real time based on actual usage, substantially increasing the useable life over a-priori cycle or hour limits based on assumed worst-case operating conditions. However, these new algorithms are complex, consume substantial computing resources, and generate enormous amounts of data that must be archived to allow data mining and/ ...
