Abstract: A window control system includes a plurality of electro-optic devices configured to control a transmittance of light through each of the plurality of zones, and at least one sensor configured to identify an intensity of light transmitted through the at least one window. A controller k in communication with the electro-optic devices and the at least one sensor. The controller is configured to independently control the transmittance of the light through each of the zones based on at least one of a direction of the light and an intensity of the light detected in a passenger compartment of a vehicle.

Each of the web substrates form a plurality of perimeter edges. A first edge is in connection with a first electrical terminal connecting in connection with a first electrode. A second edge opposing the first edge is in connection with a second electrical terminal in connection with a second electrode. A third edge and an opposing fourth edge comprise a barrier seal in a first configuration in connection with an exterior surface of each of the first web substrate and the second web substrate. The barrier seal encapsulates the electro-optic medium between an interior surface of each of the first web substrate and the second web substrate.

Abstract: An overmold is disclosed, wherein the overmold may be incorporated into a window assembly. The overmold comprises a base portion and a receiving portion. The receiving portion may comprise a notch or a channel operable to receive a window. The window may be such that when coupled with the overmold, the sides of the overmold and the window are substantially co-planar. Accordingly, window may comprise a first and a second substrate, wherein the second substrate is coupled to a first side of the first substrate. Further, the first substrate may extend beyond the second substrate. Therefore, the overmold, when in abutting contact with the window, may extend onto the first side of the first substrate up to the second substrate

Abstract: An electro-optic element having a groove is disclosed herein. The electro-optic element may include first and second substrates, first and second electrodes, an electro-optic medium, and first and second electrical buses. The first substrate may have a first surface, a second surface, and a first peripheral edge. The second substrate may be substantially parallel to the first substrate and have a third surface, a fourth surface, and a second peripheral edge. The groove is defined by a first and/or second substantially flat groove surfaces. The first groove extends between the second surface and the first peripheral edge or the first surface at a non-orthogonal angle. The second groove surface extends between the third surface and the second peripheral edge or the fourth surface at a non-orthogonal angle. The first and second electrical buses are disposed in the groove and are electrically connected to the first and second electrodes, respectively.
