  • Patent number: 11230266
    Abstract: A laminated glazing and related detection method is described. The laminated glazing has a detecting device to determine the presence of mist on a surface of the glazing and/or the presence of an object contacting or proximal the glazing. The detecting device including transmitter means for emitting a beam of electromagnetic radiation, detector means for detecting electromagnetic radiation and a target for non-specular reflection of first beam of electromagnetic radiation. The transmitter means is configured to emit the beam of electromagnetic radiation to illuminate the target such that electromagnetic radiation reflects therefrom to illuminate a region of a major surface of the glazing. At least a portion of the electromagnetic radiation reflected off the region is detectable by the detector means to provide a detection signal for detecting mist on the region and/or the presence of an object contacting or proximal the glazing. A detection method is also described.

  • Patent number: 9967922
    Abstract: A glazing comprising a transparent substrate, a plurality of electrically conductive filaments extending over the transparent substrate, wherein the filaments are shaped into a sequence of portions of the perimeters of ellipses, wherein ellipse axial ratios of the ellipses are in the range 1.1 to 4.0 and are selected so that from a pre-defined viewing position and in corresponding pre-defined viewing directions the ellipses in the plane of substrate are viewed as circles. In a preferred embodiment, major axis angles are selected so that from a pre-defined viewing position and in corresponding pre-defined viewing directions the ellipses in the plane of substrate are viewed as circles. In an example of a heated vehicle window, diffraction patterns caused by oncoming headlights interacting with heating filaments of a vehicle window are thereby minimized.

  • Patent number: 8836592
    Abstract: Laminated vehicle glazing with a conductive panel defining slot antennas between the conductive panel and the metal surround of the vehicle with connecting leads, and a camera or other device in an area where the device and the antenna do not overlap.

  • Patent number: 8613997
    Abstract: A laminated glazing panel includes two glass plies and a plastic ply having one or more light emitting diodes mounted on a circuit board laminated between the glass plies, forming an LED device. The circuit board is ordinarily a flexible circuit board that includes a substrate and a conductive layer. A plurality of light emitting diodes may be mounted on the flexible circuit board and laminated between the glass plies The resultant glazing panel may further include indicia on at least one ply. Processes for the production of a laminated glazing panel involve positioning an LED device in a cut-out in a plastic ply and interleaving the plastic ply between two glass plies, prior to laminating the plies. One or more plastic plies may be used, and the LED device may be coated in a plastic material.
