摘要： Directional antennas comprising substantially identical radiation patterns separated in a horizontal plane by an index angle. A line of bearing to an emitter is determined by a ratio of the power level of an EM signal received by the directional antennas and comparing it to a lookup table to determine an angle off of the boresight of the directional antenna with the highest received power level of the EM signal toward the directional antenna with the second-highest received power level of the EM signal that the emitter of the EM signal is located.

摘要： An image display to provide a realistic 3D stereoscopic image of a desired scene. The display device is comprised of directional pixels. Each directional pixel has a plurality of facets having a constrained viewing angle. Each facet has a point source of light that emits light with a controllable luminescence and hue. In this regard, each facet of the directional pixel has a constrained viewing angle and independent luminance and hue.

摘要： An impedance matching network between a transmitter and an antenna. The impedance matching network comprises of a watt meter coupled to the transmitter for measuring a standing wave ratio (“SWR”). A first unbalanced to unbalanced transformer (“first unun”) with an impedance ratio of N:1 is selectively coupled in series with the watt meter. A microprocessor is coupled to the watt meter for determining iteratively whether the first unun lowers the standing wave ratio (“SWR”) in response to switching the first unun in and out of a series connection with the antenna.

摘要： A far-field antenna characterization system for characterizing a far-field antenna pattern of a target antenna. An unmanned aircraft system (“UAS”) with a flight control system receives preprogrammed flight instructions for maneuvering the UAS within the far-field antenna pattern of the target antenna. A sensing antenna mounted to the UAS senses the far-field antenna pattern of the target antenna. A power measurement sensor provides a power level signal indicative thereof. A position measurement sensor provides a position signal for the UAS. The data logger associates the power level signal with the position signal at multiple measurement points to create a power density pattern for the far-field antenna pattern.

摘要： 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.

摘要： 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.

摘要： 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.
