Abstract: An electrical control system for controlling a variable transmittance window is disclosed. The system comprises a driver circuit in communication with an electro-optic element. A controller is in communication with the driver circuit. The controller is configured to identify a temperature condition of the electro-optic element and adjust an output voltage supplied to the electro-optic element in response to the temperature condition.

Abstract: An electrode for an electrochromic device includes a resistive layer disposed over a conductive layer. The resistive layer is disposed between the conductive layer and an electrochromic material in the electrochromic device. The electrode reduces non-uniform response of the electrochromic material when the electrochromic device is in operation.

Abstract: A control system for variable transmittance windows is disclosed. The system comprises at least one electro-optic element, a local control circuit, and a feedback circuit. The local control circuit is in communication with the electro-optic element via a conductive supply. The feedback circuit is in communication with the conductive supply and configured to communicate a feedback signal to the local control circuit. The local control circuit is configured to receive the feedback signal and adjust an output voltage transmitted to the conductive supply in response to the feedback signal.

Abstract: A window assembly is provided that includes an electro-optic element with a first substantially transparent substrate defining first and second surfaces. The second surface has 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 cavity is defined between the first and second substrates. An electro-optic medium is disposed in the cavity. The electro-optic medium is variably transmissive such that the electro-optic element is operable between substantially clear and darkened states. A pane is positioned proximate the electro-optic element and an infrared reflective film is positioned on at least one of the pane and the electro-optic element.
