Abstract: An improved optical collection and transmission surface includes a plastic mold injection surface including staggered multiple transmission sites each with a recessed portion in which incident light is not lost during reflection towards the propagation surface. A device implementing the surfaces is plastic-mold injected of high quality acrylic at in a preferred embodiment and can be economically optionally polished or finished to achieve desired quality surfaces.

Abstract: The present invention provides for a laser diode light diffusion unit that comprises a casing 10 with a lens cover that holds a laser diode mounted 2 on a heat sink 16, a mirror 12, a collimator lens 4 and a holographic diffusion screen 8. The casing 10 is made of a rigid thermally conducting material, and the heat sink is mounted within the casing such that a concentrated beam of light 3 produced by the laser diode 2 is directed at the mirror 12. The concentrated beam of light 3 directed at the mirror is reflected at approximately 90° into the base of the collimator lens 4, where the collimator lens 4 converts the concentrated beam 3 of light into a plane of light 6 that is projected over and in opposite direction to the path of the concentrated beam of light 3. The plane of light 3 then passes through the holographic diffusion screen 8, where the holographic diffusion screen spreads the plane of light at predetermined angles which then passes through the lens cover and out of the casing.

Abstract: A fastener is configured for use in the manufacture of molded plastic components that will be subsequently attached to other components by the fastener. The low profile head portion of the fastener has a rounded contoured and convoluted top surface to facilitate the flow of plastic material around the head portion during the molding process. The underside of the head portion is formed with a square face surrounded circumferentially by circumferential land surfaces that provides a high pull-out force resistance for the fastener. The square face on the underside and convoluted top surface of the head portion provides a high spin-out torque resistance without sacrificing the pull-out force resistance. The rounded edges of the head portion are compatible with molding processes to allow the flow of plastic material to fully encapsulate the head portion within the molded plastic component.
