    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.

    Abstract: Antenna systems for controlled coverage in buildings are disclosed where a data communications network in a building includes one or more external antennas. At least one of the external antennas is disposed on a roof or exterior of the building disposed in or associated with a window, a sky sensor or a digital architectural element. The one or more external antennas are coupled to a network infrastructure of the building via one or more data carrying lines and/or wireless links and are configured for communication with an external wireless network. The network infrastructure includes one or more data carrying lines, one or more network switches, and at least one control panel. In some embodiments, at least one of the external antennas is configured for communication with an external wireless network.

    Abstract: This disclosure provides spacers for smart windows. In one aspect, a window assembly includes a first substantially transparent substrate having an optically switchable device on a surface of the first substrate. The optically switchable device includes electrodes. A first electrode of the electrodes has a length about the length of a side of the optically switchable device. The window assembly further includes a second substantially transparent substrate a metal spacer between the first and the second substrates. The metal spacer has a substantially rectangular cross section, with one side of the metal spacer including a recess configured to accommodate the length of the first electrode such that there is no contact between the first electrode and the metal spacer. A primary seal material bonds the first substrate to the metal spacer and bonds the second substrate to the metal spacer.
