Devices that produce high-power radio frequency and optical radiation can be hazardous to operate and can lead to overexposures in humans. Because human experiments are undesirable, analysts use software chains to predict exposures: these range from simulations of the devices to propagation of the electromagnetic waves through the environment and finally to simulations of effects in human tissue. ...

Invocons Wireless Intra-vehicle Sensor Package for Enhanced Reliability (WISPER) will decrease the cost and increase the reliability of instrumenting launch vehicles. WISPER will accomplish these goals in two ways:(1) Minimize vehicle weight - this increases the useful payload or decreases the propulsion requirements.(2) Minimize physical interconnects - this simplifies integration, testing, and l ...

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 ...

The production of semi-conductor wafers is a multibillion dollar industry. The 1996 worldwide semiconductor market is estimated at $162 billion with a growth potential to $309 billion by the year 2000. Thus, even a small improvement in control during the manufacturing process could have a large impact on the economic viability of many companies and products. A critical factor in all semiconduct ...

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 ...

Navy aircraft data are stored in several database management systems, both in digital format (data recorders and sensors) and paper records. Additionally, with respect to life management and maintenance, and repair and overhaul (MRO) activities. This approach results in multiplicity of data, some contradictory data, and incomplete data. An efficient Web-Based platform is needed with a reasoning en ...
