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 ...

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 DEVELOP A REPETITIVE, FAST-OPENING SWITCH FOR PULSED-POWER APPLICATIONS EMPLOYING SATURABLE MAGNETIC MATERIALS. THIS TECHNOLOGY HAS PROVEN EFFECTIVE AND RELIABLE IN ELECTRONIC SWITCHING SYSTEMS (ESS) USED IN TELEPHONE EXCHANGES. FOR PHASE I WE WILL DESIGN A PROOF- OF-PRINCIPLE EXPERIMENT; OPTIMIZING THE DESIGN, WHILE TAKING INTO ACCOUNT CONSIDERATIONS OF COST. SUCH A SYSTEM WOULD BE ...

The research is to develop a sheet flow sampler to collect highway washoff and to operate in a highway roadside environment. The proposed sampler is expendable, simple, and cost effective. It will collect a predetermined depth of runoff (most commonly the first 1/2 inch of "first flush"), store it, and be removed and replaced by maintenance workers following rain events. The sampler will be its ...
