Patent number: 9030725Abstract: 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: GrantFiled: November 20, 2012Date of Patent: May 12, 2015Assignee: View, Inc.Inventors: Anshu Pradhan, Disha Mehtani, Gordon Jack

Patent number: 9007674Abstract: Electrochromic devices and methods may employ the addition of a defect-mitigating insulating layer which prevents electronically conducting layers and/or electrochromically active layers from contacting layers of the opposite polarity and creating a short circuit in regions where defects form. In some embodiments, an encapsulating layer is provided to encapsulate particles and prevent them from ejecting from the device stack and risking a short circuit when subsequent layers are deposited. The insulating layer may have an electronic resistivity of between about 1 and 108 Ohm-cm. In some embodiments, the insulating layer contains one or more of the following metal oxides: aluminum oxide, zinc oxide, tin oxide, silicon aluminum oxide, cerium oxide, tungsten oxide, nickel tungsten oxide, and oxidized indium tin oxide. Carbides, nitrides, oxynitrides, and oxycarbides may also be used.Type: GrantFiled: February 8, 2013Date of Patent: April 14, 2015Assignee: View, Inc.Inventors: Sridhar K. Kailasam, Robin Friedman, Dane Gillaspie, Anshu A. Pradhan, Robert Rozbicki, Disha Mehtani

Patent number: 8864321Abstract: 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.Type: GrantFiled: December 2, 2011Date of Patent: October 21, 2014Assignee: View, Inc.Inventors: Disha Mehtani, Gordon Jack, Anshu Pradhan

Publication number: 20140160550Abstract: “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.Type: ApplicationFiled: August 15, 2013Publication date: June 12, 2014Applicant: View, Inc.Inventors: Stephen C. Brown, Dhairya Shrivastava, David Walter Groechel, Anshu Pradhan, Gordon Jack, Disha Mehtani, Robert T. Rozbicki

Publication number: 20140138242Abstract: Described are methods of fabricating lithium sputter targets, lithium sputter targets, associated handling apparatus, and sputter methods including lithium targets. Various embodiments address adhesion of the lithium metal target to a support structure, avoiding and/or removing passivating coatings formed on the lithium target, uniformity of the lithium target as well as efficient cooling of lithium during sputtering. Target configurations used to compensate for non-uniformities in sputter plasma are described. Modular format lithium tiles and methods of fabrication are described. Rotary lithium sputter targets are also described.Type: ApplicationFiled: April 20, 2012Publication date: May 22, 2014Applicant: VIEW, INC.Inventors: Martin John Neumann, Disha Mehtani, Sridhar Kailasam, Trevor Frank, Todd Martin, Jason Satern, Que Anh Song Nguyen, Dhairya Shrivastava, Martin John Neumann, Anshua A.
