  • Patent number: 9412290
    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.

  • Publication number: 20160097960
    Abstract: This present invention relates to bus bar configurations and fabrication methods of non-rectangular shaped (e.g., triangular, trapezoidal, circular, pentagonal, hexagonal, arched, etc.) optical devices. The optical device comprises a first side, a second side, and a third side adjacent to the second side and two bus bars spanning a portion of the optical device.

  • Publication number: 20150346576
    Abstract: Controllers and control methods apply a drive voltage to bus bars of a thin film optically switchable device. The applied drive voltage is provided at a level that drives a transition over the entire surface of the optically switchable device but does not damage or degrade the device. This applied voltage produces an effective voltage at all locations on the face of the device that is within a bracketed range. The upper bound of this range is associated with a voltage safely below the level at which the device may experience damage or degradation impacting its performance in the short term or the long term. At the lower boundary of this range is an effective voltage at which the transition between optical states of the device occurs relatively rapidly. The level of voltage applied between the bus bars is significantly greater than the maximum value of the effective voltage within the bracketed range.

  • Patent number: 8864321
    Abstract: A controller or control method may be designed or configured to operate without information about the current temperature of the device and/or the device's environment. Further, in some cases, the controller or control method is designed or configured to control transition of an optical device to an intermediated state between two end states. For example, the controller may be configured to control a transition to a state of transmissivity that is intermediate between two end states of transmissivity. In such case, the device has three or more stable states of transmissivity.

  • Publication number: 20140160550
    Abstract: “Smart” controllers for windows having controllable optical transitions are described. Controllers with multiple features can sense and adapt to local environmental conditions. Controllers described herein can be integrated with a building management system (BMS) to greatly enhance the BMS's effectiveness at managing local environments in a building. The controllers may have one, two, three or more functions such as powering a smart window, determining the percent transmittance, size, and/or temperature of a smart window, providing wireless communication between the controller and a separate communication node, etc.

  • Publication number: 20130278988
    Abstract: This disclosure provides configurations, methods of use, and methods of fabrication for a bus bar of an optically switchable device. In one aspect, an apparatus includes a substrate and an optically switchable device disposed on a surface of the substrate. The optically switchable device has a perimeter with at least one corner including a first side, a second side, and a first vertex joining the first side and the second side. A first bus bar and a second bus bar are affixed to the optically switchable device and configured to deliver current and/or voltage for driving switching of the device. The first bus bar is proximate to the corner and includes a first arm and a second arm having a configuration that substantially follows the shape of the first side, the first vertex, and the second side of the corner.
