Abstract: A system and method of operating a sensor array are provided. The method includes adjusting the reverse bias voltage for the photodiode of at least one pixel in the sensor array based on previous output values of one or more pixels in the array, algorithms, and/or user inputs.

Abstract: A method of extending color depth in a display includes determining pixel sub-intervals for pixel intervals in a video signal, modulating a transmissivity of a display panel of the display from one sub-interval to another sub-interval, and modulating backlight intensity of a backlight from the one sub-interval to the another sub-interval.

Abstract: A sensor includes a light detector for dividing light in an environment into optical zones and detecting light from the optical zones. The sensor also includes a processor coupled to the light detector; and a memory coupled to the processor for storing the detected light as historic light readings.

Abstract: Apparatus for use with a moving map display system for freezing the moving map at a predetermined position. Analog video signals corresponding to the predetermined map position are digitized and stored in memory. The digitized signals are retrieved and converted back to video signals for continuous display during the freezing function. The moving map display system returns to normal operation upon completion of the function. A built in test capability is implemented by switching in a fixed signal, converting and storing, and then verifying the signal in memory.

Abstract: A digital flight guidance system includes a pair of processors, each with its own memory means and arranged with common input and output means for providing monitored guidance of an aircraft when the craft is in cruise modes or when the craft is performing a critical maneuver such as landing, terrain following, or the like.

Abstract: A digital control system features built in test equipment including analog input signal and discrete input signal wrap around implementations for testing the system to achieve maintainability goals without significantly adding to system configuration requirements.

Abstract: A voter circuit with averaging means eliminates a deadzone characteristic inherent in prior art voter circuits when unvoted or unwanted input signals are near zero. Elimination of the deadzone characteristic renders the voter usable in small signal regions.
