Patent number: 10120258Abstract: 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.Type: GrantFiled: June 28, 2016Date of Patent: November 6, 2018Assignee: View, Inc.Inventors: Gordon Jack, Anshu Pradhan

Publication number: 20180143502Abstract: 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.Type: ApplicationFiled: January 19, 2018Publication date: May 24, 2018Inventors: Anshu A. Pradhan, Disha Mehtani, Gordon Jack

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.Type: ApplicationFiled: September 14, 2017Publication date: March 8, 2018Inventors: Gordon Jack, Sridhar K.

Publication number: 20170045795Abstract: This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.Type: ApplicationFiled: August 22, 2016Publication date: February 16, 2017Inventors: Stephen C.
