Abstract:
A window transmissivity control assembly having a power source with scalable size and power capacity is provided. The assembly includes an insulated glazing unit including a variably transmissive glazing, a photovoltaic module attached to the insulated glazing unit and electrically coupled to the variably transmissive glazing, and a control module having a control circuit for controlling transmissivity of the glazing and a battery for providing power to the glazing. The photovoltaic assembly is attached to an exterior face portion of the insulated glazing unit, and a control module is attached to an interior face portion of the insulated glazing unit. Each module may extend from a first end of the insulated glazing unit to an opposing second end of the insulated glazing unit, wherein the length of the module being substantially the same as the distance between the first and second ends of the insulated glazing unit.
Abstract:
An electrochromic device includes an electrochromic stack. Openings are formed in the electrochromic stack that allow light to pass through without being tinted.
Abstract:
An electrochromic device is structured to selectively heat one or more particular regions of a conductive layer of the electrochromic device. An electrical potential difference can be induced across the conductive layer to heat one or more layer regions. The conductive layer can be one of at least two conductive layers on opposite sides of an electrochromic film stack, and an electrical potential difference can be induced between the conductive layers to cause at least some of the electrochromic film stack to change transmission levels. The conductive layer can include regions with different sheet resistances, so that one or more regions are structured to generate more heat than other regions of the conductive layer when an electrical potential difference is induced across the conductive layer. Separate layer regions can include separate chemical species. The conductive layer can be geometrically structured so that some layer regions have a greater sheet resistance than other regions.

Abstract:
A control device for controlling the transmittance of an electrochromic device includes a power source, an electrical load sensing circuit, and a processor electrically coupled to the electrical load sensing circuit and a power source. The processor is configured to receive a measured electrical load value from the electrical load sensing circuit indicating an electrical property of the electrochromic device, further configured to control one or more properties of the electrochromic device by controlling the amount of current or voltage supplied from the power source to the electrochromic device, and yet further configured to vary a property of the electrochromic device while maintaining the electrochromic device at a substantially consistent transmissivity.
