Abstract: A seat belt clamp comprises a clamp member which clamps the belt against a frame base when an abnormally high pull-out force is exerted on the belt. The clamp member is forced toward the belt by the combined effects of the wedging action of a roll around which the belt turns against a wedging surface of the clamp member and oblique guides on the frame which cam the clamp member toward the base and away from the roller. Springs urge both the roller and the clamp member toward released positions for easy, smooth release of the belt when the high pull-out force ceases.

Abstract: A process for selectively modifying the electrical characteristics of selected MOS devices in an integrated circuit, such as in programming a read-only memory, at or near the final stage of circuit fabrication, includes the formation of a photoresist layer over the passivation layer of a nearly completed structure. Relatively narrow openings are formed in the photoresist at those locations at which it is desired to modify the underlying MOS devices, and wider openings are formed over the locations of bonding pads. Ion implantation is carried out through the narrow openings in the photoresist layer--the photoresist acting as an implantation barrier--to modify the underlying MOS devices. An oblique angle ion milling procedure is carried out in which the walls of the photoresist layer shield the passivation layer exposed by the narrow openings in the photoresist layer so as to remove the exposed portion of the passivation layer only over the bonding pad locations. The photoresist layer is subsequently removed.

Abstract: A flight simulator combines flight data and polygon face terrain data to provide a CRT display at each window of the simulated aircraft. The data base specifies the relative position of each vertex of each polygon face therein. Only those terrain faces currently appearing within the pyramid of vision defined by the pilots eye and the edges of the pilots window need be displayed at any given time. As the orientation of the pyramid of vision changes in response to flight data, the displayed faces are correspondingly displaced, eventually moving out of the pyramid of vision. Faces which are currently not visible (outside the pyramid of vision) are clipped from the data flow. In addition, faces which are only partially outside of pyramid of vision are reconstructed to eliminate the outside portion. Window coordinates are generated defining the distance between each vertex and each of the boundary planes forming the pyramid of vision.
