Abstract: Aspects of this disclosure concern controllers and control methods for applying a drive voltage to bus bars of optically switchable devices such as electrochromic devices. Such devices are often provided on windows such as architectural glass. In certain embodiments, the applied drive voltage is controlled in a manner that efficiently drives an optical transition over the entire surface of the electrochromic device. The drive voltage is controlled to account for differences in effective voltage experienced in regions between the bus bars and regions proximate the bus bars. Regions near the bus bars experience the highest effective voltage. In some cases, feedback may be used to monitor an optical transition. In these or other cases, a group of optically switchable devices may transition together over a particular duration to achieve approximately uniform tint states over time during the transition.

Abstract: A tintable window is described having a tintable coating, e.g., an electrochromic device coating, for regulating light transmitted through the window. In some embodiments, the window has a transparent display in the window's viewable region. Transparent displays may be substantially transparent when not in use, or when the window is viewed in a direction facing away from the transparent display. Windows may have sensors for receiving user commands and/or for monitoring environmental conditions. Transparent displays can display graphical user interfaces to, e.g., control window functions. Windows, as described herein, offer an alternative display to conventional projectors, TVs, and monitors. Windows may also be configured to receive, transmit, or block wireless communications from passing through the window. A window control system may share computational resources between controllers (e.g., at different windows). In some cases, the computational resources of the window control system are utilized by other building systems and devices.

Abstract: This disclosure relates generally to optically-switchable devices, and more particularly, to systems, apparatus, and methods for controlling optically-switchable devices. In some implementations, an apparatus for controlling one or more optically-switchable devices includes a processing unit, a voltage regulator and a polarity switch. The processing unit can generate: a command voltage signal based on a target optical state of an optically-switchable device, and a polarity control signal. The voltage regulator can receive power at a first voltage and increase or decrease a magnitude of the first voltage based on the command voltage signal to provide a DC voltage signal at a regulated voltage. A polarity switch can receive the DC voltage signal at the regulated voltage to maintain or reverse a polarity of the DC voltage signal based on the polarity control signal. The polarity switch can output the DC voltage signal at the regulated voltage and at the polarity based on the polarity control signal to power the optically-switchable device. In some other implementations, the apparatus includes a processing unit, an energy storage device, and first and second voltage regulators.

Abstract: Techniques are described for generating a graphical user interface for providing information and controlling optically switchable windows connected by a network. Windows are graphically represented using interactive smart objects that are placed within views of the graphical user interface in a manner corresponding to their physical location. In another aspect, a method, system, and/or computer program product is described for associating network IDs of optically switchable windows with the locations at which the windows are installed. Window locations are determined by analyzing received wireless transmissions that are sent from transmitters associated with each of the optically switchable windows. The determined locations are then compared with a representation of the building that provides the window locations. Upon comparison, the network ID of each window, which is communicated through the window transmissions, is associated with the appropriate window location on the representation of the building.

Abstract: Electrochromic window systems and components thereof are disclosed, more particularly systems where electrochromic devices are powered and/or controlled using photonic energy. In some instances, a laser is driven by a driver to deliver photonic power and/or control information into an optical fiber. The optical fiber carries the power and control information to a photovoltaic converter and a controller. The photovoltaic converter and controller may be included within an insulated glass unit (IGU). The photovoltaic converter converts the light energy into electrical energy used to power a transition in an optical state of an electrochromic layer or layers within the IGU. The controller may be used to control the power delivered to the electrochromic layer(s), such that a smooth transition occurs. In some embodiments, control information may be transmitted in an upstream manner to communicate information regarding, for example, the state of an electrochromic device.
