An electrically heatable laminated automotive glazing unit including an exterior glass sheet that is curved and tempered and a thin glass interior sheet that is also tempered, these sheets being joined by means of a thermoplastic interlayer sheet. The glazing unit is configured to receive mechanical moving and/or fastening means and a portion of the exterior sheet is not covered by the thin interior sheet. The glazing unit is fastened in the zone not covered by the thin sheet, and the glazing unit includes at least one electrically heatable zone comprising (i) a substantially transparent, electrically conductive coating layer and (ii) spaced busbars adapted to supply electrical voltage across the substantially transparent, electrically conductive coating layer. The spaced busbars are placed in the portion of the exterior sheet which is not covered by the thin interior sheet.

An improved laminated assembly comprising functional elements with connections extending outside of the laminated assembly preventing air, moisture and water from entering the assembly as well as a method to prevent air, moisture and water from entering a laminated assembly.

A polyvinyl acetal resin film, having an average surface roughness Rz of at least one surface of 3.0 μm or less; a birefringence Δn of 3.0×10.sup.−4 or less; and an average thickness of 200 μm or less.

A circuit-including film comprising: a resin film (1); and a conductive fine wire circuit (A) and a conductive circuit (B) independent of the conductive fine wire circuit (A), which are arranged on one surface of the resin film (1), wherein the resin film (1) contains at least one resin selected from the group consisting of a polyvinyl acetal resin, an ionomer resin and an ethylene-(vinyl acetate) copolymer resin.

A system such as a vehicle may have windows. A window may have a structural window layer formed from one or more glass layers. A conductive coating such as an infrared-light blocking coating or other optical filter layer may be formed on the window. The conductive coating may include one or more silver layers or other conductive material. Unpatterned portions of the conductive coating are conductive along orthogonal dimensions. A region of the conductive coating may have parallel line-shaped openings that render the coating conductive in only a single dimension while enhancing radio transparency. Another region of the conductive coating may have a two-dimensional pattern of openings such as a mesh-shaped opening formed from intersecting straight and/or curved lines. In this region, the coating is locally rendered insulating and radio-frequency transparent. Antennas and ohmic heating elements may be formed in the coating.
