    Abstract: This disclosure provides systems, methods, and apparatus for controlling transitions in an optically switchable device. In one aspect, a controller for a tintable window may include a processor, an input for receiving output signals from sensors, and instructions for causing the processor to determine a level of tint of the tintable window, and an output for controlling the level of tint in the tintable window. The instructions may include a relationship between the received output signals and the level of tint, with the relationship employing output signals from an exterior photosensor, an interior photosensor, an occupancy sensor, an exterior temperature sensor, and a transmissivity sensor. In some instances, the controller may receive output signals over a network and/or be interfaced with a network, and in some instances, the controller may be a standalone controller that is not interfaced with a network.

    Abstract: Various implementations relate generally to a multi-sensor device. Some implementations more particularly relate to a multi-sensor device including a ring of radially-oriented photosensors. Some implementations more particularly relate to a multi-sensor device that is orientation-independent with respect to a central axis of the ring. Some implementations of the multi-sensor devices described herein also include one or more additional sensors. For example, some implementations include an axially-directed photosensor. Some implementations also can include one or more temperature sensors configured to sense an exterior temperature, for example, an ambient temperature of an outdoors environment around the multi-sensor. Additionally or alternatively, some implementations can include a temperature sensor configured to sense an interior temperature within the multi-sensor device. Particular implementations provide, characterize, or enable a compact form factor. Particular implementations provide, characterize, or enable a multi-sensor device requiring little or no wiring, and in some such instances, little or no invasion, perforation or reconstruction of a building or other structure on which the multi-sensor device is mounted.

    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: Disclosed are platforms for communicating among one or more otherwise independent systems involved in controlling functions of buildings or other sites having switchable optical devices deployed therein. Such independent systems include a window control system and one or more other independent systems such as systems that control residential home products (e.g., thermostats, smoke alarms, etc.), HVAC systems, security systems, lighting control systems, and the like. Together the systems control and/or monitor multiple features and/or products, including switchable windows and other infrastructure of a site, which may be a commercial, residential, or public site.

    Abstract: In one aspect, a method, system, and/or computer program product is 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: Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and/or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.

    Abstract: Various embodiments herein relate to networks of electrochromic windows. The networks may be configured in particular ways to minimize the likelihood that the windows on the network draw more power than can be provided. The network may include particular hardware components that provide additional power to windows as needed. The network may also be configured to adjust how the windows therein transition to prevent overloading the network. The techniques described herein can be used to design networks of electrochromic windows that are undersized when considering the amount of power that would be needed to simultaneously transition all the windows on the network using normal transition parameters, while still allowing simultaneous transitions to occur.
