Abstract: A system suitable for determining a location of an emitter emitting a radiation signal from an unknown location has a vehicle with a location position determining apparatus to receive a location datum, so the location of the vehicle can be determined when the radiation signal is received. A sensor connected to a receiver is positioned on the vehicle to detect and receive the radiation signal at a plurality of locations. A processor having a program executing therein determines the power level of the radiation signal at each measurement location and determines the location of the emitter from the change in power level of the radiation signal between measurement locations.

Abstract: A method is provided for individually processing multiple frequency bands in a composite RF signal is disclosed. The composite RF signal is separated into a plurality of gain controlled and bandlimited frequency bands. The gain controlled and bandlimited frequency bands are then recombined to produce a controlled composite RF signal, which is then digitized by undersampling with an ADC to produce a plurality of unambiguous frequency bands convolved around baseband. The sample frequency can be substantially less than the Nyquist Limit of twice the highest frequency present for digitization. Each baseband signal is monitored for amplitude spikes therein. In response to an amplitude spike, the appropriate frequency band is modified by a control signal to hold the ADC to within its dynamic range.

Abstract: An optical sensing system for detecting objects passing through a volume of interest, wherein the sensing system has an emitter and a detector. The detector detects motion of object shadows generated as the object passes through the volume of interest between the emitter and detector. Motion detection algorithms, using computed motion vectors of the detected object, logically determine whether an object has traveled completely through the detection space, and can be used to discriminate a specific outcomes and/or impediments.

Abstract: A system detects the location of an uncooperative emitter by measuring the power level in an RF signal using a grid of linear antennas. The linear antennas are arranged in an x,y axis with intersections strategically placed in areas of interest. A detector detects the power level in each of the leaky signal cables. A processor in communication with the detector identifies the cable intersection having the greatest power level and associates that intersection as the location of the uncooperative emitter.

Abstract: A circuit and method is provided for determining the frequency of a signal of interest in a wideband composite RF signal. An analog preprocessor is configured to receive a composite RF signal from an antenna and produce bandlimited frequency sub-bands S1 to Sn. An image converter is configured to receive and alias the bandlimited frequency sub-bands S1 to Sn to baseband and generate a first alias-band output signal and a second alias-band output signal. A processor is configured to receive the two alias-band output signals and determine the frequency shift of the signal of interest between the two alias-band output signals and calculate the frequency for the signal of interest using the frequency shift.

Abstract: An expandable structure formed from a single piece of material is moveable between a stowed position and an extended position. The structure has a base and a plurality of support members integral with the base that move between a stowed position and an extended position. In the stowed position, the base and the plurality of support members are essentially a two dimensional shape. A biasing force makes the structure self-erecting and moves it to the extended position. In the extended position, the expandable structure has a hollow interior and a cross-section that is bounded by a closed path.
