  • Heat treatable coated article with diamond-like carbon (DLC) and/or zirconium in coating
    Patent number: 7507442
    Abstract: In certain example embodiments, a coated article includes respective layers including diamond-like carbon (DLC) and zirconium nitride before heat treatment (HT). During HT, the hydrogenated DLC acts as a fuel which upon combustion with oxygen produces carbon dioxide and/or water. The high temperature developed during this combustion heats the zirconium nitride to a temperature(s) well above the heat treating temperature, thereby causing the zirconium nitride to be transformed into a new post-HT layer including zirconium oxide that is scratch resistant and durable. In certain example embodiments, the zirconium nitride and/or zirconium oxide may be doped with F and/or C.

  • Light sensor embedded on printed circuit board
    Patent number: 7504957
    Abstract: A system and/or method for sensing the presence of moisture (e.g., rain) and/or other material(s) on a window such as a vehicle window (e.g., vehicle windshield, sunroof or backlite). Such techniques may be used in connection with a light sensor. In certain example embodiments, a flexible printed circuit board (PCB) includes a light sensor comprising a light sensor flip-chip, with the light sensor flip-chip including at least two light sensor arrays, and with each said sensor array being configured to sense light of a predetermined wavelength. An adhesive bonds the light sensor to the PCB. A hole is formed in the PCB and the opaque layer so as to allow the light sensor arrays to see through the hole formed in the PCB and the opaque layer. A state of the vehicle lights is settable in dependence on the light sensor. The PCB is located in or is supported by the vehicle windshield.

  • Rain sensor with sigma-delta modulation and/or footprinting comparison(s)
    Patent number: 7492270
    Abstract: A system and/or method for sensing the presence of moisture (e.g., rain) and/or other material(s) on a window such as a vehicle window (e.g., vehicle windshield, sunroof or backlite). In certain example embodiments of the invention, at least one sensing capacitor is supported by a window such as a vehicle windshield, the capacitor(s) having a field that is affected by moisture (e.g., rain) on a surface of the window. A sensing circuit outputs an analog signal that is based on and/or related to the capacitance(s) of the sensing capacitor(s). The analog output of the circuit may be converted to a digital signal via sigma-delta modulation, and subjected to processing (e.g., correlation) for determining whether moisture (e.g., rain, dew, fog, etc.) or the like is present on the surface of the window.

    Patent number: 7052585
    Abstract: A coated article is provided which includes a layer including titanium oxycarbide. In order to form the coated article, a layer of titanium oxide is deposited on a substrate by sputtering or the like. After sputtering of the layer including titanium oxide, an ion beam source(s) is used to implant at least carbon ions into the titanium oxide. When implanting, the carbon ions have sufficient ion energy so as to knock off oxygen (O) from TiOx molecules so as to enable a substantially continuous layer comprising titanium oxycarbide to form near a surface of the previously sputtered layer.
