Abstract: Systems and methods for measuring air speed which solve the problem of icing or blockage by creating an exterior surface on an aircraft that channels air and measures the pressure difference of the pressure through the airflow and the static pressure. This exterior surface cannot be blocked easily because air is always flowing when the aircraft is in motion, any external matter that could be on the exterior surface is readily visible, and the exterior surface can be heated to prevent icing. In addition, the exterior surface is made of a flexible material that is able to conform closely to the exterior shape of the aircraft. The preferred embodiments comprise microelectromechanical system pressure sensors placed under the air channels for measuring the pressure difference in each channel and an air speed processor for transforming the pressure differences into an air speed estimate.

Abstract: A collision avoidance system includes a monopulse radar antenna array of monopulse radar antenna segments mounted to a vehicle with respective fixed fields of view. Each monopulse radar antenna segment comprises a comparator network configured to form a sum signal representing a summation of return signals and a first difference signal representing a first difference of the return signals. The system further includes a user interface configured to present information in a form perceptible to a person operating the vehicle and a radar antenna array controller configured to calculate a range of the object and a first (azimuth) angle of arrival of the return signal from the object. The comparator network is further configured to form a second difference signal which the radar antenna array controller uses to calculate a second (elevation) angle of arrival.

Abstract: Systems and methods for processing a multitude of variable and varying signals in real time with low latency using fixed hardware with fixed processing resources, such as those within an application-specific integrated circuit (ASIC) or a field-programmable gated array (FPGA). The signal processing systems and methods allow the resource allocation to continuously adjust their processing as a result of changing signal conditions. In accordance with various embodiments, fixed processing resources in ASIC or FPGA form are dynamically allocated through an intelligent interleaving methodology that efficiently maps the signal processing of incoming signals while essentially preserving the same latency as if each signal channel were processed at the full sample rate. This is accomplished by multiplexing under the control of a resource sharing algorithm.

Abstract: A method of inspecting a wire contact includes determining, at a processor, a striation metric of a particular image of the wire contact. The particular image depicts an inspection hole in the wire contact. The method also includes comparing the striation metric to a wire-in-hole detection threshold and determining that a threshold number of visible wire strands are oriented along a particular axis in the inspection hole if the striation metric satisfies the wire-in-hole detection threshold.
