The present teaching relates to approaches for dynamic light blocking in a moving vehicle. Sensor data from sensors deployed on a vehicle are received that capture information exterior and interior around the vehicle. The presence of a person in the vehicle is detected based on interior sensor data while a light source exterior to the vehicle is detected based on exterior sensor data. A portion of a window of the vehicle through which light from the light source shines on the person is determined and an appropriate level of shade is applied on the portion of the window to reduce the amount of light shining on the person.

Systems and methods provide technology for a tunable vehicle window system to adjust a view for a window. The technology includes a window assembly comprising a tunable optical metamaterial deployed on a surface of a window, the tunable optical metamaterial including a transparent electroactive substrate having disposed thereon an optically active particle array, the optically active particle array including resonators having elongated members arranged in two or more orientations. The technology includes a controller to receive a signal from a photosensor indicative of a condition of incoming light to the vehicle, determine a change in a view for the window assembly based on the received photosensor signal, and control a voltage applied to the substrate to selectively expand or contract the substrate within a plane substantially parallel to the window surface and in a manner to adjust the view for the window assembly according to the determined view change.

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.
