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: A method of controlling tint of a tintable window to account for occupant comfort in a room of a building. The tintable window is between the interior and exterior of the building. The method predicts a tint level for the tintable window at a future time based on lighting received through the tintable window into the room at the future time and space type in the room. The method also provides instructions over a network to transition tint of the tintable window to the tint level.

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: A method, system, and/or computer program product 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 placed within views of the graphical user interface in a manner corresponding to their physical location. A method, system, and/or computer program product are 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: 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.

Abstract: Various embodiments herein relate to power distribution networks for optically switchable windows. A number of different topologies are provided. In many embodiments, a control panel may be connected with a trunk line, which is connected to a plurality of optically switchable windows. The plurality of optically switchable windows may be powered by the shared trunk line. This topology provides substantial improvements over topologies in which each optically switchable window is connected to the control panel via separate, individual lines. Further, certain embodiments herein relate to installation kits for installing power distribution networks for optically switchable windows.

Abstract: A site monitoring system may analyze information from sites to determine when a device, a sensor, a controller, or other structure associated with optically switchable devices has a problem. The system may, if appropriate, act on the problem. In certain embodiments, the system learns customer/user preferences and adapts its control logic to meet the customer's goals.
