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 ...

Virtual reality-based training systems are becoming a reality. Significant advances in photo-realistic image rendering has made reasonably priced high performance computer generated visuals commonplace. While development of the visual aspect of a virtual world is a significant artistic enterprise, it is no longer technically difficult. Similarly, computer capture and generation of digitized soun ...

ALONG WITH TREMENDOUS ADVANCES IN THE TECHNOLOGY SUPPORTING GRAPHICAL AND HEADS-UP DISPLAYS COMES A DIZZYING ARRAY OF OPTIONS FOR THE DISPLAY OF COMPLEX STATIC AND DYNAMIC INFORMATION TO PILOTS IN MODERN AIRCRAFT. TO DATE, RESEARCH ON THE EFFECTIVENESS OF GRAPHICAL DISPLAY FORMATS AS AIDS TO DECISION-MAKING AND MONITORING HAS BEEN LARGELY EQUIVOCAL (JARVENPAA AND DICKSON, 1988) (SANDERSON, FLACK, ...
