Abstract: A mobile device and system which simulates human motion. The device includes a base with a drive system for providing motion to the device. A receiver is provided which controls the drive system the receiver receives wireless control signals. Pads and a self-stabilizing component are provided on the device. The device accurately mimics the unpredictable motion of a human motion to provide a safer alternative to live interaction to increase participant safety and decrease the incidence of injuries during practice or drill sessions. The system includes at least one mobile device. The mobile device includes: a base having a drive system for providing motion to the device; a receiver which controls the drive system the receiver receives wireless control signals; and self-stabilizing component provided on the device. The system also includes a transmitter for transmitting the control signals to the receiver.

Abstract: A microbolometer imaging apparatus having an array of selectable substrate-isolated microbolometer detectors, a detector selection controller, and a readout circuit. The detectors may be exposed to a scene of interest, and each detector has a corresponding resistor value. The detector selection controller may selectively couple an electrical bias source to each detector. The readout circuit may establish an output signal representative of the resistance value of each detector. The readout circuit includes a feedback bias control circuit modulates the electrical bias source as a function of the output signal.

Abstract: In accordance with the present invention, a microbolometer focal plane array is provided with at least one thermally-shorted microbolometer detector that is thermally shorted to the microbolometer focal plane array substrate. A characteristic relationship is empirically derived for determining a corrected resistance value for each detector of the microbolometer focal plane array in response to radiation from a target scene as a function of the corresponding detector resistance value, the thermally-shorted microbolometer detector resistance value, and the empirically derived characteristic relationship.

Abstract: A method and apparatus for controlling bias for an microbolometer focal plane array which includes use of one thermally-shorted microbolometer detector thermally shorted to the substrate upon which one or more thermally-isolated microbolometers are constructed. A calibration bias source magnitude is determined and continually adjusted as a function of (i) the temperature related reading value of the resistance of the thermally-shorted microbolometer at calibration, and (ii) the temperature related reading value of the resistance of the thermally-shorted microbolometer after each image sample is taken.
