A small, personnel, battlefield, fiber optic sensor for detection of heartbeat and respiration rates will be developed. This biosensor offers high sensitivity, simplicity of design, and low costs. The contractor will show the feasibility of a personnel biosensor which has the potential to signal fatigue, dehydration, stress, illness, injury, or sleep disorders which are detectable through low fr ...

Researchers at Virginia Commonwealth University have developed decision support software, called WorkWORLD, for analyzing the financial effects of current and alternative "work incentive" policies on individuals who receive various disability and welfare benefits. Decision Technology Network (DTN), Inc. proposes: (1) to further develop WorkWORLK as an individual counseling and decision-making too ...

RECENT ADVANCES IN MICROCOMPUTER TECHNOLOGY HAVE MADE IT POSSIBLE FOR VISUALLY IMPAIRED PERSONS TO CONTINUE NORMALLY WITH THEIR EDUCATION. VOICE SYNTHESIZERS AND TEXT MAGNIFI CATION ENABLE HANDICAPPED INDIVIDUALS TO BEAR RO READ BOOKS,MAGAZINES, AND OTHER PUBLICATIONS WHICH ARE STORED IN D N DIGITAL FROM IN THE MICROCOMPUTER. THE RECENT INTRODUCTION OF A LOW COST, MANUALLY OPERATED, OPTICAL SCANNE ...

Wind noise in outdoor measuemetn micropnones can mask an acoustic signal. Windscreens provide some wind noise reduction; however, those typically used for outdoor applications provide noise reductions of approximately 10-15 dB. Planning Systems Incorporated (PSI) proposes to design and test a Multiple Aperture Sensor System (MASS) consisting of a microphone, a processor, and data acquisitio and ...

The current market for fast switching frequency sythesizers is growing rapidly. Most synthesizers available today will not meet the stringent requirements for switching quickly, providing spectrally pure RF outputs and minimizing physical size and cost. As part of a current SBIR program, S.T. Research has developed a wideband, fast switching synthesizer, based on the use of broadband phase-locke ...

BEAMFORMING METHODS IN WHICH THE FAST CONVOLUTION TECHNIQUE IS APPLIED TO EXECUTE MULTICHANNEL TIME DELAY FIR INTERPOLATION FILTERING IS THE SUBJECT OF THIS PROPOSAL. THE METHOD OFFERS THE POTENTIAL FOR EXECUTING CERTAIN PRIOR AND POST BEAMFORMING FIR FILTER-ING OPERATIONS WITHIN THE BEAMFORMER PROCESSING TO ENHANCE OVERALL SYSTEM COMPUTATIONAL EFFICIENCY. TWO FAST CONVOLUTION METHODS BASED ON DIF ...

Large field-of-regard (FOR) scanners are often desirable for poassive and active optical-infrared (IR) sensor systems for applications such as imaging, ladar, precision munitions, space-based surveillance, security surveillance, remote sensing, and free-space optical communications. The large FOR scanners for precision munitions need to be fast, small, light, rugged, low in power consumption, and ...

WE PROPOSE TO MEASURE ICE THICKNESS FROM A SUBMERGED SUBMARINE BY MEASURING THE ATTENUATION OF THE COSMIC RAY PRODUCED NETURON FLUX. A SIMILAR TECHNIQUE HAS BEEN USED SUCCESSFULLY TO MEASURE SNOW THICKNESS. TWO NEUTRON DECTORS, POSSIBLE BF3, WOULD OPERATE IN COINCIDENCE MODES TO REDUCE BACKGROUND CONTRIBUTIONS. THE DETECTION GEOMETRY WOULD DETERMINE THE APERTURE AND, THEREFORE, SIZE OF ICE AREA ME ...
