Patent number: 9638977Abstract: Methods, apparatus, and systems for mitigating defects in optical devices such as electrochromic devices. One method mitigates a pinhole defect in an electrochromic device by identifying the site of the pinhole defect and obscuring the pinhole to make it less visually discernible. In some cases, the pinhole defect may be the result of mitigating a short-related defect.Type: GrantFiled: March 13, 2013Date of Patent: May 2, 2017Assignee: View, Inc.Inventors: Robin Friedman, Sridhar K. Kailasam, Rao Mulpuri, Ronald M. Parker, Ronald A. Powell, Anshu A. Pradhan, Robert T. Rozbicki, Vinod Khosla

Publication number: 20170003566Abstract: Methods, apparatus, and systems for mitigating pinhole defects in optical devices such as electrochromic windows. One method mitigates a pinhole defect in an electrochromic device by identifying the site of the pinhole defect and obscuring the pinhole to make it less visually discernible.Type: ApplicationFiled: August 30, 2016Publication date: January 5, 2017Inventors: Robin Friedman, Sridhar Karthik Kailasam, Rao Mulpuri, Ronald M.

Publication number: 20160327846Abstract: Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and/or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition.Type: ApplicationFiled: July 19, 2016Publication date: November 10, 2016Inventors: Sridhar Karthik Kailasam, Robin Friedman, Anshu A. Pradhan, Robert T. Rozbicki

Publication number: 20160251894Abstract: Thin-film devices, for example, multi-zone electrochromic windows, and methods of manufacturing are described. In certain cases, a multi-zone electrochromic window comprises a monolithic EC device on a transparent substrate and two or more tinting zones, wherein the tinting zones are configured for independent operation.Type: ApplicationFiled: April 8, 2016Publication date: September 1, 2016Inventors: Dhairya Shrivastava, Robin Friedman, Vinod Khosla, Rao Mulpuri

Publication number: 20160154289Abstract: Window units, for example insulating glass units (IGU's), that have at least two panes, each pane having an electrochromic device thereon, are described. Two optical state devices on each pane of a dual-pane window unit provide window units having four optical states. Window units described allow the end user a greater choice of how much light is transmitted through the electrochromic window. Also, by using two or more window panes, each with its own electrochromic device, registered in a window unit, visual defects in any of the individual devices are negated by virtue of the extremely small likelihood that any of the visual defects will align perfectly and thus be observable to the user.Type: ApplicationFiled: February 2, 2016Publication date: June 2, 2016Inventors: Robin Friedman, Sridhar K. Kailasam, Rao Mulpuri, Ronald A. Powell, Dhairya Shrivastava

Patent number: 9229291Abstract: 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: January 20, 2015Date of Patent: January 5, 2016Assignee: View, Inc.Inventors: Sridhar K.

Publication number: 20150103389Abstract: A portable controller having a portable power supply for transitioning tint of an optical device such as an electrochromic device. The portable power supply has at least one battery located within a housing and a support structure for supporting the battery. The portable controller has circuitry with logic for controlling power to the optical device. In some cases, the portable power supply may provide a higher than normal drive voltage to the optical device to accelerate transition to the tint state and then may reduce the drive voltage to a normal level.Type: ApplicationFiled: May 24, 2013Publication date: April 16, 2015Applicant: VIEW, INC.Inventors: Erich R.
