  • Method of making window unit
    Publication number: 20110000602
    Abstract: A method of making a window unit is provided which may result in improved yields. In certain example embodiments, the method involves coating a substrate with both (i) a solar control/management coating, and (ii) a protective layer (e.g., of or including diamond-like carbon (DLC)) over the solar control/management coating. The protective layer protects the coated substrate from scratches and/or the like during processing prior to heat treatment. Then, during heat treatment, the protective layer(s) is burned off in part or in whole. Following heat treatment, the coated article (substrate with solar control/management coating thereon) is coupled to another substrate in order to form the window unit.

  • Rain sensor embedded on printed circuit board
    Patent number: 7830267
    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, a plurality of sensing capacitors are supported by a window such as a vehicle windshield, the capacitors each having a different field and/or pattern. A sensing circuit outputs an analog signal that is based on and/or related to the capacitances of one or more of the sensing capacitors. In certain example embodiments, a flexible printed circuit board (PCB) mountable in or on a vehicle window is provided. First and second sensing circuits are formed on opposing sides of the flexible PCB, with each said sensing circuit comprising a plurality of different fractal structures.

  • Heat treatable coated article with diamond-like carbon (DLC) and/or Zirconium in coating
    Publication number: 20100273002
    Abstract: In certain example embodiments, a coated article includes respective layers including hydrogenated 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 very scratch resistant and durable.

  • Coated article having low-E coating with ion beam treated IR reflecting layer and corresponding method
    Patent number: 7820019
    Abstract: A coated article is provided that may be used as a vehicle windshield, insulating glass (IG) window unit, or the like. An ion beam is used to treat an infrared (IR) reflecting layer(s) of such a coated article. Advantageously, this has been found to improve sheet resistance (Rs) properties, emittance, solar control properties, and/or durability of the coated article.

  • Rain sensor for detecting rain or other material on window of a vehicle or on other surface
    Publication number: 20100242587
    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 or backlite). In certain example embodiments, a capacitor-based system and/or method is provided for auto-correlating sensor data to determine the existence of a material on the window, and then cross-correlating sensor data to identify the type and/or amount of that material (e.g., rain). This data may be used to actuate and/or deactivate a vehicle's wiper(s), and/or adjust wiper speed. In certain example embodiments, the sensor may include an array of at least two capacitors. In certain example embodiments, the system and/or method may perform check(s) to enhance the accuracy of the detection by comparing, for example, the sign of autocorrelation values, maximum autocorrelation values, and/or gradients of autocorrelation values.

  • Rain sensor with sigma-delta modulation and/or footprinting comparison(s)
    Patent number: 7775103
    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.

  • Method of making heat treatable coated article with protective layer
    Publication number: 20100047464
    Abstract: A soda inclusive glass substrate is coated with a highly tetrahedral amorphous carbon inclusive layer that is a form of diamond-like carbon (DLC). In certain embodiments, the amorphous carbon layer includes at least about 35% sp3 carbon-carbon bonds, more preferably at least about 70%, and most preferably at least about 80% of the sp3 carbon-carbon bonds. The high density (e.g. greater than or equal to about 2.4 gm/cm3) of the amorphous carbon layer prevents soda from exiting the glass and reacting with water at surface(s) of the glass, thereby minimizing visible stains (or corrosion) on the glass. The high density amorphous carbon layer also may repel water. In some embodiments, the highly tetrahedral amorphous carbon layer is part of a larger DLC coating, while in other embodiments the highly tetrahedral layer forms the entirety of a DLC coating on the substrate.
