Patent ID: 7019260

Claim:
An automotive windscreen glazing panel in which the glazing panel perimeter comprises at least a top edge, a bottom edge and first and second side edges, the bottom edge being longer than the top edge and substantially parallel thereto and each of the side edges being substantially the same length as each other and shorter than the top edge, in which the glazing panel is provided with an electrically heatable solar control coating layer over at least part of its surface area, in which the glazing panel is provided with a data transmission window adapted to permit electromagnetic data transmission therethrough, in which the data transmission window permits transmission of a greater proportion of incident electromagnetic data than the proportion of incident electromagnetic data transmitted by an equivalently sized portion of the glazing panel provided with the solar control coating, in which the data transmission window is at least in part surrounded by the coating layer and is positioned adjacent to either the top edge or the bottom edge of the glazing panel, in which the first bus bar is arranged substantially adjacent to and extends substantially along the first side edge of the glazing panel, and in which the second bus bar is arranged substantially adjacent to and extends substantially along the second side edge of the glazing panel, in which the arrangement of the solar control coating, the bus bars and the data transmission window is such as to allow the coating layer to cover at least the majority of the light transmitting surface of the windscreen without provoking significant perturbation in the heating arrangement of the coating layer.
