    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, the apparatus includes an interface for communicating with window controllers, and the apparatus includes one or more processors. A processor can be configured to cause status information received from a window controller to be processed. The status information can indicate at least a tint status of one or more optically-switchable devices controlled by the window controller. In response to receiving the status information, one or more tint commands can be sent via the interface to the window controller.

    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.

    Abstract: FIG. 1 is a front view of an obround flush-mount faceplate.
    FIG. 2 is a rear view of the obround flush-mount faceplate of FIG. 1.
    FIG. 3 is a left side view of the obround flush-mount faceplate of FIG. 1.
    FIG. 4 is a right side view of the obround flush-mount faceplate of FIG. 1.
    FIG. 5 is a bottom view of the obround flush-mount faceplate of FIG. 1.
    FIG. 6 is a top view of the obround flush-mount faceplate of FIG. 1.
    FIG. 7 is an isometric view of the obround flush-mount faceplate of FIG. 1.
    FIG. 8 is a front view of the obround flush-mount faceplate of FIG. 1 in an in-use state with a smartglass controller shown mounted therewith; and,
    FIG. 9 is an isometric view of the obround flush-mount faceplate in the in-use state of FIG. 8.
    Dashed or broken lines and a lack of shading depict environmental subject matter that is not part of the claimed faceplate but is included to provide further context for the claimed design. Such environmental subject matter includes the back face of the obround flush-mount faceplate, as well as the obround smartglass controller portion seen in FIGS. 8 and 9 in the in-use state.
    Stipple shading is used to show surface contouring and is not indicative of surface texture. Dash-dot-dash boundary lines are used to indicate transitions between broken line/unshaded areas and solid line/shaded areas.

    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.
