  • Publication number: 20110045172
    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: 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.

    Abstract: Electrolyte solutions for electrochromic devices such as rear view mirrors and displays with low leakage currents are prepared using inexpensive, low conductivity conductors. Preferred electrolytes include bifunctional redox dyes and molten salt solvents with enhanced stability toward ultraviolet radiation. The solvents include lithium or quaternary ammonium cations, and perfluorinated sulfonylimide anions selected from trifluoromethylsulfonate (CF3SO3?), bis(trifluoromethylsulfonyl)imide ((CF3SO2)2N?), bis(perfluoroethylsulfonyl)imide ((CF3CF2SO2)2N?) and tris(trifluoromethylsulfonyl)methide ((CF3SO2)3C?). Electroluminescent, electrochromic and photoelectrochromic devices with nanostructured electrodes include ionic liquids with bifunctional redox dyes. Some of the electrolyte solutions color to red when devices employing the solutions are powered, leading to red or neutral electrooptic devices.
