  • Patent number: 8947772
    Abstract: An inorganic, dielectric grid polarizer device includes a stack of film layers disposed over a substrate. Each film layer is formed of a material that is both inorganic and dielectric. Adjacent film layers each have different refractive indices. At least one of the film layers is discontinuous to form a form-birefringent layer with an array of parallel ribs having a period less than 400 nm. Another layer, different than the form-birefringent layer, is formed of an optically absorptive material for the ultra-violet spectrum.
    Type: Grant
    Filed: March 5, 2014
    Date of Patent: February 3, 2015

  • Patent number: 6098265
    Abstract: An apparatus and method for positioning a latch assembly and a striker on a motor vehicle is disclosed. The apparatus is designed to improve the fit of the tailgate to the side walls or truck body. A good fit is defined as the outer surface of the tailgate and the outer surface of the side wall being coplanar when the tailgate is in the closed position. The apparatus, by way of a first formation and first locating element, determines the position of the latch assembly with respect to outer surface of the tailgate. The apparatus, by way of a second formation and second locating element, also determines the location of the striker with respect to the outer surface of the side walls. The apparatus, by way of a body member, also determines the position of the striker with respect to the latch assembly and vice versa. By setting the latch assembly and the striker by the above relations, build variances of the tailgate and of the truck body are eliminated as a possible cause for a poor fit.

  • Patent number: 6092271
    Abstract: A tool for aligning a striker with a latch for a door on a motor vehicle includes a base member and a tool locating member positioned perpendicular to an end of the base member. The tool also includes a tool holding mechanism positioned on a front face of the tool locating member for holding the alignment tool onto the vehicle, and a striker locating arm extending outwardly from another end of the base member. The alignment tool further includes a striker lead-in at one end of the striker locating arm for positioning the striker relative to the latch, and a cross member extending between another end of the striker locating arm and the base member for receiving the latch.
