  • Patent number: 11629551
    Abstract: A unitary electro-optic window assembly includes a window element. A first substantially transparent substrate defines a first surface, a second surface, and a first peripheral edge. A second substantially transparent substrate defines a third surface, a fourth surface, and a second peripheral edge. The first and second substantially transparent substrates define a cavity therebetween. An electro-optic medium at least partially fills the cavity and is configured to reduce light transmissivity of the window element. A controller is adjacent to the window element and is in electrical communication therewith. The controller is configured to change a voltage applied to the electro-optic medium to change the light transmissivity of the window element. An interface is in electrical communication with the controller. A transparent dust cover is positioned over the window element, the controller, and the interface.
