Abstract: A wideband simultaneous transmit and receive (STAR) subsystem for a radar or communications system including self-interference cancellation and external noise cancellation. The STAR subsystem includes a canceller circuit which digitally prepares a cancellation signal to cancel out leaked or reflected portions of the transmit signal and correlated noise in the receiver signal. The self-interference cancellation can be adaptively configured in a closed-loop mode, and operated open loop in real time to minimize bandwidth limitations and achieve wideband performance. The STAR subsystem also includes an external noise active canceller which greatly diminishes high-power external noise in the receiver signal. The external noise canceller digitally synthesizes a cancellation signal which dramatically improves the signal-to-noise ratio in the receiver. Together, the combined cancellation techniques prevent receiver saturation and preserve receiver sensitivity.

Abstract: A system includes a controller that includes a processor and a memory. The processor executes computer-executable instructions stored in the memory to operate the controller. The instructions cause the controller to determine at least two beam patterns for separate transmit beams that operate within the field of regard to be scanned by a Radio Detection and Ranging (RADAR) beam generator. The instructions also cause the controller to generate beam pattern commands to the RADAR beam generator to generate the beam patterns. The beam pattern commands specify a pointing direction for each of the separate transmit beams that operate within each portion of the field of regard.

Abstract: An angle grinder attachment which creates a portable, cordless, dustless, indoor ceramic tile cutting machine. There is no dust produced when using this attachment. The dust (and silica) are turned into a paste which is easily cleaned and disposed of. This attachment does not require electricity or running water in the field.

Abstract: Higher-resolution imagery of an airport runway can be provided from the pilot's point of view. Pilot point of view images may be generated using images captured by higher-resolution ground-based cameras. The images from the ground-based cameras are fed to a point of view processor that generates the pilot point of view images using aircraft position information. The pilot point of view images are transmitted to a display on the aircraft.

Abstract: An apparatus for attenuating vibration transmission between first and second structures includes a rod extending entirely through, and being mechanically connected to, both of the first and second structures. The rod defines a central longitudinal axis. A piezoelectric sensor senses vibrations in at least one of the first and second structures and responsively generates a voltage. The piezoelectric sensor is disposed entirely longitudinally between the first and second structures. A piezoelectric actuator actively attenuates the vibrations sensed by the piezoelectric sensor. The piezoelectric actuator is at least partially driven responsive to voltage generated by the piezoelectric sensor. The piezoelectric actuator is disposed entirely longitudinally between the first and second structures. At least one of the piezoelectric sensor and the piezoelectric actuator has a throughhole through which the rod entirely extends.
