Abstract: A demonstrator for mounting, operating and displaying a multiplicity of automotive vehicle components comprises an open-frame exoskeleton of aluminum tubes. The tubes are in a configuration suggestive of the shape of an automotive vehicle. The demonstrator is light in weight, is easily shipped and is movable by a single person. A central compartment of the exoskeleton resembles a passenger compartment and has doorways similar in height and width to door openings of the vehicle. A front compartment of the demonstrator resembles a vehicle engine compartment, this compartment defining a generally horizontal window free of other structure of the demonstrator. The front compartment includes front wheel-well outlines defined by tube segments welded together. A rear compartment of the demonstrator similarly defines rear wheel-well outlines.

Abstract: Electrical control system for a video tracker, including circuitry for maintaining the size of the target substantially constant relative to the tracking window, thereby improving the accuracy of the target shift detection circuit. Additional circuitry is provided for enhancing contrast between the target and the background scene, thus preventing loss of the target due to inadvertant sensing of grey clutter instead of the true target.
