  • Patent number: 11566468
    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.

  • Patent number: 11543723
    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.

  • Patent number: 11520207
    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.

  • Publication number: 20220382224
    Abstract: Optically controllable windows and an associated window control system provide a building security platform. A window controller or other processing device can monitor for window breakage, cameras associated with windows can monitor for intruders, and transparent displays can provide alerts regarding detected activity within a building. A window control system can detect deviations from expected I/V characteristics of an optically controllable window during normal operation of the window (tint transitions, steady state conditions, etc.) and/or during application of a security-related perturbing event, and provide alerts upon their occurrence.

  • Patent number: 11513412
    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).

  • Publication number: 20220365399
    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. Also described are self-meshing networks for electrochromic windows.

  • Publication number: 20220365494
    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.

  • Publication number: 20220351950
    Abstract: Various embodiments herein relate to carriers for supporting one or more substrate as the substrates are passed through a processing apparatus. In many cases, the substrates are oriented in a vertical manner. The carrier may include a frame and vertical support bars that secure the glass to the frame. The carrier may lack horizontal support bars. The carrier may allow for thermal expansion and contraction of the substrates, without any need to provide precise gaps between adjacent pairs of substrates. The carriers described herein substantially reduce the risk of breaking the processing apparatus and substrates, thereby achieving a more efficient process. Certain embodiments herein relate to methods of loading substrates onto a carrier.

  • Publication number: 20220334445
    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.
