The present invention relates to a laminated glass for a vehicle, the laminated glass having an intermediate film between an outer glass plate and an inner glass plate, includes: a test area A defined by JIS Standard R3212; an information transmitting/receiving area in which a device installed in a vehicle transmits and/or receives information; a film capable of heating the information transmitting/receiving area, the film being adhered to an area that is outside of the test area A and overlaps the information transmitting/receiving area in a planar view between the intermediate film and either one of the outer glass plate or the inner glass plate.

An antenna with a heater and method for using the same are disclosed. In one embodiment, the antenna comprises: an antenna aperture having a plurality of radio-frequency radiating antenna elements, the antenna aperture having a ground plane and a material for tuning permittivity or capacitance; and a heater structure in thermal contact with the material.

A window such as a vehicle window may have an infrared-light-blocking area formed from an infrared-light-blocking layer. The window may also have an infrared-light-transparent area formed from an infrared-light-transparent layer that is not covered by the infrared-light-blocking layer. The infrared-light-transparent layer may have a conductive layer that is transparent to near-infrared light such as a conductive oxide layer or a metal layer. The infrared-light-blocking layer may have one or more layers of infrared-light-reflecting material such a silver layer that is electrically coupled to the conductive layer in the infrared-light-transmitting layer. Ohmic heating current may be passed to the conductive layer in the infrared-light-transmitting layer through the conductive layer in the infrared-light-blocking layer or through elongated metal contacts that run along edges of the infrared-light-transmitting layer.

A pane having an electric heating layer is described, including: a first pane having a surface; at least one electric heating layer that is applied to at least part of the surface and has at least one uncoated zone; at least two busbars, provided for connection to a voltage source, which are connected to the electric heating layer such that a current path for a heating current is formed between the busbars; and n separating lines which electrically subdivide the electric layer into m segments. The segments are arranged in the form of strips around the uncoated zone such that the current path for the heating current is at least partially guided around the uncoated zone and the segments have equal width and the sum of widths of segments is equal to the width of the electric heating layer.

A laminated glass for a vehicle includes a first glass plate, a second glass plate, an interlayer, a first busbar and a second busbar arranged such that a visible area is interposed in a predetermined direction between the first busbar and the second busbar, a plurality of electric heating wires arranged in the visible area to generate heat with a voltage applied by the first busbar and the second busbar, and a third busbar arranged at an opposite side of the visible area from the second busbar, wherein the third busbar and the first busbar are arranged such that an information acquisition area is interposed in the predetermined direction between the third busbar and the first busbar, and at least one of the electric heating wires is arranged in the information acquisition area to generate heat with a voltage applied by the third busbar and the first busbar.

A laminated glass having an interlayer between a glass plate on an exterior side of a vehicle and a glass plate on an interior side of the vehicle, includes a heat generator on a principal surface on a vehicle-exterior side of the glass plate that is on the interior side of the vehicle, wherein at least one of the glass plate on the exterior side of the vehicle and the glass plate on the interior side of the vehicle has a wedge shape in cross section, and wherein a maximum value of a layer thickness of the interlayer is less than or equal to 1 mm.

A heatable laminated vehicle window for separating a vehicle interior from an outer surrounding area is presented. The vehicle window includes an outer pane bonded to an inner pane via a thermoplastic intermediate layer. An electrically heatable coating of the vehicle window is electrically connected to two busbars such that by applying a supply voltage across the two bus bars, a heating current that forms heating field flows between the two busbars. In one aspect, a metal element is arranged on or in the vehicle window such that heat is dissipated out of a region of the heating field that has elevated heat generation by means of thermal conduction of the metal element.

A transparent pane having an electrically heatable coating and at least one coating-free zone that can be used, for example, as communication window, is presented. The electrically heatable coating is connected to two collecting electrodes, such that a supply voltage applied to the electrodes generates a heating current that flows via a heating field formed between the collecting electrodes, the heating field containing the coating-free zone whose zone-edge is formed, at least in sections, by the heatable coating. Other implementation details include provision of two electrical supply lines electrically connecting the two collecting electrodes to separate subdivisions of an additional electrode. In one case, the electrical supply lines run, at least in sections, in the heating field, in the coating-free zone, in a coating-free edge strip, in a subregion of the coating outside the heating field, and/or in the zone-edge. Methods for producing the transparent pane are also presented.

A heating apparatus of a window glass of a vehicle comprises a heater which generates heat for melting ice adhering to an imaging glass part including a whole part of a corresponding part within a window glass which corresponds to an imaging range of an onboard camera. The heater heats the imaging glass part in such a manner that an amount of heat per unit area applied to a specific part of the imaging glass part on an upstream side in a liquid flowing direction which is a direction in which the liquid flows on a side surface outside a vehicle cabin of the imaging glass part becomes larger than an amount of heat per unit area applied to a part of the imaging glass part on an downstream side with respect to the specific part in the liquid flowing direction.

A transparent pane, having at least one heatable, electrically conductive coating connected to at least two collection electrodes, provided for electrically connecting to a supply voltage to generate a heating current that flows across a heating field formed between the at least two collection electrodes is described. The heating field includes at least one communication window free from the heatable, electrically conductive coating. The transparent pane further includes at least one heatable, electrically conductive coating. The additional electrode is connected to one of the two collection electrodes via a respective current supply line.
