  • Patent number: 8310757
    Abstract: A light transmissive panel comprising a first sheet and a second sheet, wherein each sheet is made up of a non-birefringent substrate and a wire grid polarizer pattern of continuously varying absorption axis orientation formed on the non-birefringent substrate. The wire grid polarizer patterns on each of the first and second sheet are mechanically translatable relative to each other, wherein the mechanical translation controls transmission of light through the light transmissive panel. Light transmissive panels wherein each sheet of the panel is made of a wire grid polarizer that is laminated with a continuous variable thickness wave plate retarder, wherein the continuous variable thickness wave plate retarder rotates input light by an amount determined by the thickness of the wave plate retarder.

  • Patent number: 5131680
    Abstract: An inflator assembly inflates a vehicle occupant restraint. The inflator assembly includes a container which stores gas under pressure. A body of an ignitable pyrotechnic material is disposed within the container. An igniter assembly is actuatable in response to being struck to ignite the body of pyrotechnic material. An actuator assembly is provided to release the stored gas from the container and to actuate the igniter assembly. The actuator assembly includes a pyrotechnic which moves an actuator member to rupture a portion of the container and to strike the igniter assembly. Upon actuation of the igniter assembly, the pyrotechnic material is ignited and begins to burn. During initial burning of the pyrotechnic material, an orifice plate restricts a flow of combustion products to promote burning of the pyrotechic material.

  • Patent number: 4969895
    Abstract: An instrument for determining the variation in tension of a ligament graft extending between first and second proposed fixation sites positioned on first and second articulated bones, respectively, comprises a yoke which carries a device for securing the yoke to one of the first and second bones. A yoke plate is rotatably carried by the yoke. A main housing is adapted for connection to the yoke plate. A sled is slidably carried by the main housing. The sled is adapted for connection to the ligament graft. A mechanism is provided for adjusting the position of the sled relative to the housing so as to place a desired degree of tension on the ligament graft. A transducer is associated with the mechanism for adjusting for determining changes in tension, if any, from the desired degree of tension as the first and second bones are moved relative to one another.
