  • Publication number: 20070275253
    Abstract: An appliance transparency, such as an oven transparency, includes at least one substrate and a coating deposited over at least a portion of the substrate. The coating includes at least one metal layer, such as a metallic silver layer. The metal layer can have a thickness in the range of 80 ? to 100 ? and optionally or the coating can have a protective coating deposited thereon.

  • Publication number: 20070152019
    Abstract: A low temperature solder including indium in the range of 62-65 weight percent and tin in the range of 31-33 weight percent uses the heat generated during thermal treatment of one or more glass sheets to melt the solder. In one non-limiting embodiment, a lead providing external access to an electrical conductive arrangement, e.g. a conductive member between and connected to spaced bus bars between laminated sheets has an end portion of a connector, e.g. a lead soldered to each of the bus bars during thermal processing of the sheets, e.g. during the lamination of the sheets during a windshield manufacturing process. In another nonlimiting embodiment, the connector is soldered to the electrically conductive arrangement during the annealing of glass blanks following the heating and shaping of the glass blanks.

  • Publication number: 20070044542
    Abstract: A moisture detection system includes an electrical conductor disposed on a surface of a substrate, an oscillator for outputting an oscillator signal at a predetermined amplitude and a predetermined frequency, and a resonator circuit coupled to the electrical conductor and responsive to the oscillator signal for outputting a resonator signal having an amplitude related to a resonant frequency of the electrical conductor. A filter circuit responsive to the resonator signal can output a rectified and filtered signal, and an analog-to-digital converter responsive to the rectified and filtered signal can output a digital signal related to the rectified and filtered signal. A sensor can be provided having a property that varies as a function of a temperature at or adjacent the electrical conductor. A controller can be responsive to the digital signal and the property of the sensor for causing another system to operate as a function thereof.

  • Publication number: 20070020465
    Abstract: A heatable transparency includes a first ply having a No. 1 surface and a No. 2 surface and a second ply having a No. 3 surface and a No. 4 surface. The No. 2 surface faces the No. 3 surface. An electrically conductive coating is formed on at least a portion of the No. 2 or No. 3 surface, with the conductive coating including three or more metallic silver layers. An antireflective coating is formed on the No. 4 surface.

  • Publication number: 20060267856
    Abstract: An electrically conductive coating of an automotive heatable windshield has a communication window having an enhanced frequency selective surface having arranged passing areas (uncoated areas) and blocking areas (coated areas) to pass and block, respectively, predetermined wavelengths of the electromagnetic spectrum. In one nonlimiting embodiment, the frequency selective surface includes a plurality columns spaced from one another by a continuous elongated blocking area. Each of the columns includes passing areas with each of the passing areas have a perimeter with a blocking area in the perimeter spaced from the perimeter. The perimeters of the passing areas contact one another with the blocking area of adjacent passing areas spaced from one another. The elongated blocking area between the break lines and columns extend to the perimeter of the communication window.

  • Publication number: 20060186105
    Abstract: An electrically heatable transparency has at least one substrate, a first bus bar spaced from a second bus bar, and a conductive coating formed over at least a portion of the substrate. The first and second bus bars are in electrical contact with the coating. At least one of the bus bars has an end region in electrical contact with the coating. The end region is tapered such that the coating is of substantially uniform thickness on the end region.

  • Publication number: 20060010794
    Abstract: A region in a metallic panel that facilitates the transmission of radio frequency signals. The metallic panel may be included in a window such as the window of a vehicle or building. For example, the metallic panel may be used for heating or to reflect infrared radiation. An aperture is formed in the metallic panel to enable radio frequency signals to be transmitted through the metallic panel. The design of the aperture may be selected to enable the transmission of the desired frequency band. Furthermore, the aperture is designed such that there is a taper in the transmission amplitude and/or the phase to suppress lobing effects on the other side of the aperture. In an embodiment in which the metallic panel is used to conduct electric current, the aperture may be oriented such that the current may flow between the openings of the aperture. Accordingly, there may be uniform heating across the metallic panel without blocking the transmission of radio frequency signals in the desired frequency band.

  • Publication number: 20050045700
    Abstract: The invention relates to using the heat generated during thermal treatment of one or more glass sheets to melt solder. In one nonlimiting embodiment, a lead providing external access to an electrical conductive arrangement, e.g. a conductive member between and connected to spaced bus bars between laminated sheets has an end portion of a connector, e.g. a lead soldered to each of the bus bars during thermal processing of the sheets, e.g. during the lamination of the sheets during a windshield manufacturing process. In another nonlimiting embodiment, the connector is soldered to the electrically conductive arrangement during the annealing of glass blanks following the heating and shaping of the glass blanks. Soldering the leads during the annealing or laminating process eliminated possible thermal damage to the sheet by having the sheet heated during the soldering operation instead of only a small surface portion of the sheet at and eliminates the cost of a separated soldering operation.
