Abstract: Embodiments include systems and methods for assisting a pilot of an aircraft. The system includes a near-eye display and a processing subsystem. The near-eye display includes a transparent display panel that is adapted to be oriented in proximity to at least one eye of the pilot. The processing subsystem is adapted to receive aircraft data that indicates an attitude of the aircraft, and to determine whether the aircraft data indicates a potential spatial disorientation situation. When the aircraft data indicates the potential spatial disorientation situation, the processing system is adapted to cause the near-eye display to display an exterior display indicator overlying at least a portion of the windshield of the aircraft. The exterior display indicator includes a visual representation of an earth-based reference, and the exterior display indicator is oriented to indicate the attitude of the aircraft.

Abstract: A battery health or prognosis system may employ a ferrite disc embedded in a printed wiring board (PWB) to perform both a battery current sensing role and a temperature sensing role. The ferrite disc may be surrounded with a coil that may be comprised of surface conductors and electrically conductive vias of the PWB. Excursions of coil current may be produced to generate observable hysterisis loops in the ferrite disc. The generated hysterisis loops may be compared to a temperature-dependent family of hysterisis loops for the magnetic material from which the ferrite disc is constructed. A processor mounted on the PWB may collect and process outputs from a Hall-effect sensor to develop both temperature and battery current information to produce a prognosis for the battery.

Abstract: To effective increase the dynamic range of a pixel array, a plurality of brightness groups is set. The pixels of a pixel array are then distributed among the groups according with their likely brightness. Each image frame is scanned in the order of brightness, with the pixels in the group likely to be the brightest being scanned first and the pixels in the group likely to be the darkest being scanned last. The brightness groups are adjusted at the boundary of the frame scan.
