摘要： The window (1, 80, 100) is intended to be fitted with an imaging device (30), e.g. a camera, which views an object through a viewing area (2, 102) of the window. To avoid impairment of the image by ice or condensation on the viewing area, the window comprises a resistance heating element (23, 50, 60, 70, 90, 101) arranged to heat a localised area (3, 81, 103) of the window including the viewing area (2, 102). The window may be laminated from at least two plies of glazing material (20, 21) and at least one ply of interlayer material (22) extending between the plies of glazing material, with the heating element laminated between the plies of glazing material. Electrical connection means (40, 109) are provided for connecting the heating element to an electrical supply, and an opaque coating (4, 83, 104) may be provided to conceal the edges of the heating element from view. The window may be a windscreen for a vehicle.
