    摘要: An electric heating and capacitive sensing arrangement that includes: an electrically conductive heating track arranged on a surface of a planar substrate, the electrically conductive track being connectable to a current source so that during a heating operation a current flows through the electrically conductive track. The electrically conductive track is connectable to a capacitive sensing circuit so that during a sensing operation a capacitive sensing signal is applied to the electrically conductive track. The electrically conductive track has at least a first and a second heating track section extending at a distance along each other on the substrate, whereby a gap is formed between the first and the second heating track section. The heating and sensing arrangement further includes a layer of electrically conductive material arranged on the surface of the substrate in the gap between the first and the second heating track section.

    摘要: A vehicle window glass according to the present invention is provided with: a glass plate; a light-shield layer stacked on a peripheral portion of the glass plate; a defogger of which at least a part is disposed in a light-transmissive region of the glass plate surrounded by the light-shield layer; and a first antenna disposed lower than the defogger on the glass plate. The vertical width of a part of the light-shield layer stacked on an upper end portion of the glass plate is 25 to 200 mm. The vehicle window glass satisfies a1+b1≥0.5λ, where a1 is the shortest of the horizontal lengths of the light-transmissive region, b1 is the vertical length of the light-transmissive region, and λ is the wavelength of radio waves received by the first antenna.

    摘要: Embodiments of an electric heater apparatus are disclosed. In one embodiment, an electric heater apparatus includes: (a) a first thermally conductive layer comprising an electrically insulating material; (b) one or more electrically conductive heating elements disposed in one or more grooves arranged on the top side of the first thermally conductive layer; and (c) a second thermally conductive layer disposed on the top side of the first thermally conductive layer over the one or more heating elements. The one or more heating elements include one or more refractory hard metals doped with at least one of carbon, nitrogen, aluminum, yttrium, or oxygen. The doped one or more refractory hard metals include a temperature insensitive electrical resistance over operational temperatures ranging from ambient temperature to about 850° C. as compared to undoped refractory hard metals. The one or more heating elements are independently controllable to provide one or more heating zones.

    摘要: An improved resistive foil heater is notionally provided. The improved heater includes a coverlay, a base, an etched composite panel intermediate the coverlay and the base, transition tabs, and lead wires. The etched composite panel is characterized by a foil element, and a substrate for supporting the foil element, and the panel is adapted for passage of the transition tabs in furtherance of functional union with the lead wires. The foil element is characterized by an etched resistive foil heater, and associated transition pads. The transition tab is united to/with the transition pads of the foil element of the etched composite panel, the lead wires functionally united with the etched resistive foil heater via the transition tabs.
