Abstract
An electrically heated window for a vehicle includes a smooth surfaced transparent sheet having a plurality of spaced electric resistance heating conductors on the surface thereof. A humidity detector is provided on the inside surface of the sheet and includes two sets of conductors standing in relief above the surface of the sheet and each having substantially the shape of a comb with the teeth of the two combs interdigitated and extending substantially in the direction of maximum slope of the sheet. The back of the upper comb defines a gutter for the diversion of water droplets from the area occupied by the teeth of the combs.
