Abstract: A portable device for measuring a bioimpedance-related property of tissue includes a plurality of electrodes arranged in a pattern on a surface and associated software for measuring bio-impedance related data of localized regions of tissue and calculate health-related parameters based on the measured data. These calculated parameters may be representative of muscular health of the localized tissue region.

Abstract: An Emergency Position Indicating Radio Beacon (EPIRB) comprising an integrated wireless receiver, a graphical display device, capability to utilize both internal and external GPS coordinate sources, an infrared background lighting adjustment algorithm, and a multi-LED strobe light array. The receiver provides a return communications path back to the beacon, which is used to acknowledge the receipt of the beacon's outgoing emergency signal by Search and Rescue satellites. The display is used to visually display various operational status information as well as any received messages coming back into the receiver. The GPS receiver system switches between internally derived and/or externally supplied GPS coordinates. The present invention also incorporates an Automatic Background Light Adjustment (ABLA) algorithm to compensate for the maximum range of light intensity encountered by infrared communications LEDs during daytime and nighttime operation.

Abstract: A dual conversion, noise resistant, digitally-controlled mm-wave frequency synthesizer for generating rapidly-tunable RF signals. The prime signal-generation source is a 3.0-3.2 GHz low noise wide band voltage controlled oscillator (“vco”). The oscillator includes a buried stripline hairpin resonator having dual-tuning circuits to increase bandwidth coverage and unique bias circuitry to improve phase noise. The oscillator frequency is multiplied by a factor of two, yielding a 6.0-6.4 GHz signal that is mixed with a fixed locally generated carrier of 3900 MHz, the output of which represents the first Intermediate Frequency (IF). This IF is then mixed with 1950 MHz (3900 MHz divided by two), yielding a second IF that covers the 188 to 550 MHz range. The 2nd IF is divided down and phase locked to an external reference using a commercially available chip set. The 6.0-6.4 phase locked signal is then re-mixed with the 3.0-3.2 GHz output form the oscillator, thereby yielding a 9.0-9.6 GHz signal. The 9.
