    Abstract: A controller system configured to clear an electro-optic device may include an electro-optic device having a first substrate having a first surface and a second surface, the second surface having a first layer of electrically conductive material disposed thereon; a second substrate having a first surface having a second layer of electrically conductive material disposed thereon, and a second surface, the second substrate being approximately parallel to the first substrate such that a chamber is defined by the first and second substrates; and an electro-optic medium disposed in the chamber defined by the first and second substrates and in contact with the first and second layers of electrically conductive material; a controller in communication with the electro-optic device, wherein the controller is configured to control electrical power supplied to the electro-optic device and a potentiometer in communication with the electro-optic device and with the controller.

    Abstract: An imaging system is provided that includes an imager, an optical lens stack, and an electro-optic element positioned between the imager and the lens stack. The electro-optic element includes a first substantially transparent substrate defining first and second surfaces. The second surface includes a first electrically conductive layer. A second substantially transparent substrate defines third and fourth surfaces. The third surface has a second electrically conductive layer. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic medium is disposed within the cavity. The electro-optic medium is operable between substantially clear and substantially opaque states.

    Abstract: A variable transmission element includes a first substrate that has a first surface and a second surface opposite the first surface. A second substrate includes a third surface and a fourth surface opposite the third surface. The first and second surfaces face each other and are disposed in a spaced apart relationship so as to define a space therebetween. A seal formed of a sealing material extends along a perimeter of the first and second substrates. A first lamination layer comprises a first lamination material that is different from the sealing material and the first lamination layer is coupled to the second surface. A second lamination layer comprises a second lamination material that is different from the sealing material and the second lamination layer is coupled to the second substrate. An electro-optic device is disposed between the first lamination layer and the second lamination layer.
