Abstract: A system for monitoring graphics processing units, including an image merge element; a database memory, operatively connected to the image merge element; and, a comparator element. The image merge element is configured to: i) receive visible image data from a graphics processing unit (GPU); ii) extract a symbol identifier; iii) receive a mask; and, iv) calculate a cyclic redundancy check (CRC) of a masked portion of the visible image data corresponding to the mask. The database memory is operatively connected to the image merge element. The database memory includes: a mask database including lookup tables of masks for defined areas of the visible image data indexed by the extracted symbol identifier; and, a CRC signature database including a table of valid CRCs for the image data indexed by the extracted symbol identifier.

Abstract: The display system includes a display having a touchscreen input device. A processing system is operatively associated with the display. The display operates in a number of fixed modes. Each fixed mode has a single fixed format, each single fixed format having at least one fixed region, wherein the at least one fixed region has configurable overlay options. In an aircraft application the plurality of fixed modes are selected from the group of flight modes consisting of navigation, air-to-air (A-A), emergency, air-to-ground (A-G), preflight checklist and system status. In a preferred embodiment the emergency mode includes functionality to conserve power.

Abstract: A lighted keypanel equipped with a processor that integrates switch sensing, panel lighting control, and brightness (including ambient light compensation) to reduce cost and simplify interfaces of systems using the lighted keypanel. The lighted keypanel is particularly adaptable for use with a cockpit display.
