Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.

Abstract: In one aspect, an apparatus is described that includes a transparent pane having a first surface and a second surface. An electrochromic device is arranged over the second surface that includes a first conductive layer adjacent the second surface, a second conductive layer, and an electrochromic layer between the first and the second conductive layers. The apparatus further includes at least one conductive antenna structure arranged over the second surface.

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 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: Various implementations relate generally to multi-sensor devices. 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 further 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 include one or more of an infrared sensor or infrared sensors, a cellular communication circuit, and a GPS module.

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.

The apparatus further includes at least one conductive antenna structure arranged over the second surface.

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).

Abstract: Certain embodiments are directed to control methods, window controllers, and uninterruptible power supplies for determining tinting instructions for optically switchable windows to reduce power usage at a site during a reduced power event. In some cases, reduced power operations are initiated by a window controller upon receipt of a trigger signal from an uninterruptible power supply sent when it detects a power loss. In some cases, tinting instructions are based on the remaining charge left on the uninterruptible power supply. In some cases, reduced power operations are delayed for a period of time.

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.
