  • Patent number: 8610992
    Abstract: A variable transmission window includes a first substrate having a first transparent conductor coated surface and a second substrate having a second transparent conductor coated surface. The second substrate is positioned relative to the first substrate with the first and second transparent conductor coated surfaces facing each other. An electrochromic medium is disposed between the first and second substrates whereby the transmission of light through the electrochromic medium is changed when an electrical potential is applied thereto. The electrochromic medium includes a cross-linked film. The window may be one of (i) an aeronautical glazing and (ii) a vehicle glazing, and/or the window may be a large area glazing of an area of at least 99 square inches.

  • Patent number: 8511841
    Abstract: A vehicular blind spot indicator mirror includes a transparent glass substrate having a mirror reflector coated onto the substrate. Visible light reflectance by the mirror reflector coated substrate is at least about 40 percent visible light reflectance for visible light incident upon a front side of the mirror reflector coated substrate. A blind spot indicator light display is disposed to the rear of the mirror reflector coated substrate and emits visible light upon a detection by a blind spot detector. Light emitted by the display passes through the transparent glass substrate to be viewed by a viewer viewing from the front side of the substrate. The display is operable, when electrically powered and when operated in the vehicle during day time driving conditions, to exhibit a display luminance of at least about 60 foot lamberts as measured with the display placed behind, and emitting light through, the transparent glass substrate.

  • Patent number: 8164817
    Abstract: A method of forming a mirrored bent cut glass shape includes bending a flat sheet of glass to establish a curved sheet of glass. A machine vision system determines a surface profile of the curved sheet of glass, and a computer numerical controlled cutting tool is positioned at the curved sheet of glass and its cutting wheel is maintained at or close to 90 degrees to the tangential plane of the curved sheet of glass. At least one of (a) the cutting wheel and (b) the curved sheet of glass is controlled in three dimensions to cut a bent cut glass shape from the curved sheet of glass, and such controlling is, at least in part, responsive to the surface profile of the curved sheet of glass. A mirror reflector is established at a surface of the bent cut glass shape to form a mirrored bent cut glass shape.

  • Patent number: 7871169
    Abstract: A vehicular signal mirror includes a reflective mirror element comprising a mirror reflector on a light-transmitting substrate. The visible light reflectance is at least about 40% for visible light incident upon the front side of the reflective mirror element. A turn signal light display and/or a blind-spot indicator light display is disposed to the rear of the reflective mirror element and configured so that the light emitted by the light display passes through the reflective mirror element to be viewed by a viewer viewing from the front of the reflective mirror element. The light display exhibits, when electrically powered and when operated in the vehicle during day time driving conditions, a display luminance of at least about 60 foot lamberts as measured with the light display placed behind, and emitting light through, the reflective mirror element.

  • Patent number: 7821697
    Abstract: An exterior reflective mirror element suitable for a vehicle includes a transparent glass substrate having a reflector and a visual indicator display disposed to the rear of the substrate. The visual indicator display may be part of a blind spot detection and display system of the vehicle wherein the visual indicator display is actuated to emit light responsive to a detection by a blind spot detection detector of the equipped vehicle of an overtaking vehicle in a side lane adjacent the side of the equipped vehicle. The visual indicator display includes at least a first indicator at a first location to the rear of the exterior reflective mirror element. A first portion of the reflector may be at least partially removed at the first location in order to establish an at least partially transmissive first portion of the exterior reflective mirror element at the first location.

  • Patent number: 7589883
    Abstract: An exterior mirror suitable for use in a vehicular exterior rearview mirror assembly includes a reflective mirror element having a light transmitting substrate with a mirror reflector having a metallic reflective layer coated thereon. A visual indicator display is disposed to the rear of the light transmitting substrate and actuated to emit light when powered. Light emitted by light sources of the display passes through the light transmitting substrate so as to be viewed by a driver of the vehicle equipped with the reflective mirror element. The mirror element has portions of the metallic reflective layer at least partially removed by laser scribing to establish at least partially light transmissive portions of the mirror reflector so that light emitted by light sources, when powered, passes through the respective at least partially light transmissive portions to be viewed by a viewer viewing from the front of the reflective mirror element.

  • Patent number: 7543947
    Abstract: A rearview mirror element for a motor vehicle includes a light transmitting substrate having a visible light reflecting and visible light transmitting mirror reflector disposed on a surface thereof. A display-on-demand display device is disposed behind the substrate such that light emitted by the display device when powered passes through both the light transmitting substrate and the mirror reflector. The display device exhibits, when powered during day time driving conditions, a display luminance of at least about 60 foot lamberts. When not emitting light, the disposition of the display device to the rear of the light transmitting substrate is not substantially distinguishable to the driver of the equipped vehicle when viewing the mirror element. To the rear of the light transmitting substrate is rendered substantially opaque by a light absorbing element that is disposed at least adjacent to where, and except at where, the display device is disposed therebehind.
