Abstract: A modular computer system having an integral electronic bus includes a number of computer components each housed in a casing. Each casing includes a standardized male connector extending from the front surface of the casing and a female receptacle, which is compatible with the male electrical connector, extending into the casing from its rear surface. Each connector and receptacle includes an array of electrical contacts disposed in a predetermined arrangement, such that each connector contact is aligned with a corresponding contact of the casing receptacle. Corresponding pairs of connector and receptacle contacts mate to form the integral electronic bus. Any combination or arrangements of computer components may be electrically interconnected by engaging the receptacle of each casing with the connector of an adjacent casing, thereby forming the integral electrical bus between the interconnected modules.

Abstract: An optical processing system for processing infrared information prior to detection. In one embodiment, optical information from an infrared scene is focused by optics (10) onto a thermoptic modulator (12) which contains an optical structure (16) disposed on the faceplace of a cathode ray tube. The modulator is normally nonreflective of infrared energy from the scene incident thereon. Reflecting spots (22) written on the modulator by an electron beam reflect a portion of the scene to a detector (52) which generates a signal representative of the radiance of the scene element sampled. A series of first and second reflecting spots of different size are written at selected coordinates on the modulator. The respective signals generated by the detector for each spot of the pair are subtracted to provide a spatial band pass filtered signal for each sampling coordinate on the modulator.
