    Abstract: Window controller systems and methods are disclosed herein. In some embodiments, a window controller system for controlling multiple optically switchable devices comprises a printed circuit board comprising a first plurality of footprints to which a first plurality of components is mounted and a second plurality of footprints, wherein a subset of the second plurality of footprints is populated by a second plurality of components. The first plurality of components may comprise: a plurality of insulated glass unit (IGU) controllers, each configured to control an IGU of a corresponding plurality of IGUs operatively coupled to the window controller system; and a processing unit configured to control each of the plurality of IGU controllers. The second plurality of components may be selected based on a cable type and/or a protocol type used to provide power and data signals to the printed circuit board.

    Abstract: Conventional electrochromic devices frequently suffer from poor reliability and poor performance. Improvements are made using entirely solid and inorganic materials. Electrochromic devices are fabricated by forming an ion conducting electronically insulating interfacial region that serves as an IC layer. In some methods, the interfacial region is formed after formation of an electrochromic and a counter electrode layer, which are in direct contact with one another. The interfacial region contains an ion conducting electronically insulating material along with components of the electrochromic and/or the counter electrode layer. Materials and microstructure of the electrochromic devices provide improvements in performance and reliability over conventional devices. In addition to the improved electrochromic devices and methods for fabrication, integrated deposition systems for forming such improved devices are also disclosed.

    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.

    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.

    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). In some cases, the computational resources of the window control system are utilized by other building systems and devices.
