Abstract: An enhanced vision system (EVS) is integrated with a heads-up display (HUD). The EVS generates image of an external scene. The EVS generates the images without repeatedly generating the images when a mode of the HUD changes. The EVS includes an expanded interface, where inputs from the HUD are used in the internal processing of the EVS. The HUD then displays information in a graphical and alphanumeric format. The information can include an enhanced vision image from the EVS and/or a synthetic vision image from a synthetic vision system (SVS). The enhanced vision image can be merged with a synthetic vision image to provide a combined vision image.

Abstract: A method and apparatus for processing packetized data spanning multiple clock cycles includes at least one comparator, for comparing a present clock cycle count to a reference clock cycle count, wherein the reference clock cycle values may be anywhere within the packet and may be non-contiguous with other reference clock cycle values. At least one word recognizer, compares a presently clocked word to a reference word, and an output circuit provides an indication of a favorable word comparison that occurred in response to a favorable clock cycle count comparison.
