Abstract: An electrically heatable transparency has at least one substrate, a first bus bar spaced from a second bus bar, and a conductive coating formed over at least a portion of the substrate. The first and second bus bars are in electrical contact with the coating. At least one of the bus bars has an end region in electrical contact with the coating. The end region is tapered such that the coating is of substantially uniform thickness on the end region.

Abstract: The present invention provides an interlayer composite having a plastic sheet having a predetermined outer shape and a major surface; a pair of bus bars, and an adhesive layer securing the bus bars directly on the major surface of the plastic sheet in a fixed relationship to one another.

Abstract: A moisture detector can include a first elongated conductor disposed on a substrate. The first conductor can define a zigzag path between the opposite ends thereof. A second conductor can also be disposed on the substrate at least partially surrounding the first conductor. The second conductor can define between opposite ends thereof a zigzag path having a portion thereof that is positioned in substantially spaced parallel relation with the zigzag path of the first conductor along the sides thereof. A power conductor disposed on the substrate can be electrically connected to the first conductor intermediate the ends thereof via a gap defined between the ends of the second conductor. Ground conductors disposed on the substrate can be electrically connected to the ends of the second conductor. A temperature sensor can be utilized to correct the response of the moisture detector for temperature.

Abstract: A laminate, e.g. a heatable windshield has a pair of glass sheets laminated together about a member responsive to electrical stimuli, e.g. changes transmission or is heated as current passes through the member. A pair of spaced bus bars is in surface contact with the conductive member, and a lead assembly associated with each of the bus bars has a lead in contact with its respective bus bar and extends beyond the periphery of the sheets. The lead assembly further includes first and second air barriers to prevent air from moving between the sheets after the edge sealing procedure and during autoclaving of the laminate subassembly. The first air barrier is an adhesive between surfaces of the lead and inner surfaces of an electric and mechanical protective sleeve positioned over portions of its respective lead.
