  • WINDOW WITH ANTI-BACTERIAL AND/OR ANTI-FUNGAL FEATURE AND METHOD OF MAKING SAME
    Publication number: 20120258244
    Abstract: Certain example embodiments of this invention relate to a window having anti-fungal/anti-bacterial properties and/or self-cleaning properties, and a method of making the same. In certain example embodiments, a silver based layer is be provided and the layer(s) located thereover (e.g., the zirconium oxide inclusive layer) are designed to permit silver particles to migrate/diffuse to the surface over time to kill bacteria/germs at the surface of the coated article thereby creating an anti-bacterial/anti-fungal effect. In certain example embodiments, silver may also or instead be mixed in with other material as the top layer of the anti-bacterial coating.

  • Heat treatable coated article with diamond-like carbon (DLC) and/or zirconium in coating
    Patent number: 8277946
    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.

  • Debonding and transfer techniques for hetero-epitaxially grown graphene, and products including the same
    Patent number: 8236118
    Abstract: Certain example embodiments of this invention relate to the use of graphene as a transparent conductive coating (TCC). In certain example embodiments, graphene thin films grown on large areas hetero-epitaxially, e.g., on a catalyst thin film, from a hydrocarbon gas (such as, for example, C2H2, CH4, or the like). The graphene thin films of certain example embodiments may be doped or undoped. In certain example embodiments, graphene thin films, once formed, may be lifted off of their carrier substrates and transferred to receiving substrates, e.g., for inclusion in an intermediate or final product. Graphene grown, lifted, and transferred in this way may exhibit low sheet resistances (e.g., less than 150 ohms/square and lower when doped) and high transmission values (e.g., at least in the visible and infrared spectra).

  • Coated article with ion treated underlayer and corresponding method
    Patent number: 8147972
    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.

  • Method of making window unit
    Patent number: 8119199
    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.

  • Moisture sensor for detecting rain or other material on window or on other surface
    Patent number: 8109141
    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.
