  • Coated article with ion treated underlayer and corresponding method
    Publication number: 20090226714
    Abstract: A coated article is provided that may be used as a vehicle windshield, insulating glass (IG) window unit, or the like. Ion beam treatment is performed on a layer(s) of the coating. For example, a silicon nitride layer of a low-E coating may be ion beam treated. It has been found that ion beam treatment, for example, of a silicon nitride underlayer is advantageous in that sodium migration from the glass substrate toward the IR reflecting layer(s) can be reduced during heat treatment.

  • Rain sensor with fractal capacitor(s)
    Publication number: 20090223288
    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. The at least one sensing capacitor may have a fractal geometry in certain example embodiments of this invention. The sensing circuit may output an analog signal that is based on and/or related to the sensing capacitor(s). The analog output of the circuit may be converted to a digital signal, 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.

  • Coated article with ion treated overcoat layer and corresponding method
    Patent number: 7585396
    Abstract: A coated article is provided that may be used as a vehicle windshield, insulating glass (IG) window unit, or the like. Ion beam treatment is performed on a layer(s) of the coating. For example, an overcoat layer (e.g., of silicon nitride) of a low-E coating may be ion beam treated in a manner so as to cause the ion beam treated layer to include (a) nitrogen-doped Si3N4, and/or (b) nitrogen graded silicon nitride. It has been found that this permits durability of the coated article to be improved.

  • Method of forming coated article using sputtering target(s) and ion source(s) and corresponding apparatus
    Patent number: 7563347
    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. In certain example embodiments, an ion source(s) and a sputtering target(s) used in forming the IR reflecting layer, or any other suitable layer, may be located in a common deposition chamber of an apparatus used in forming at least part of the coating.

  • Heat treatable coated article with diamond-like carbon (DLC) and/or zirconium in coating
    Publication number: 20090142603
    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 including titanium oxycarbide and method of making same
    Patent number: 7510786
    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 (0) from TiOx molecules so as to enable a substantially continuous layer comprising titanium oxycarbide to form near a surface of the previously sputtered layer.
