Patent number: 10890820Abstract: 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: GrantFiled: September 5, 2018Date of Patent: January 12, 2021Assignee: View, Inc.Inventors: Robin Friedman, Sridhar Kailasam, Rao Mulpuri, Ronald A. Powell, Dhairya Shrivastava

Patent number: 9897888Abstract: 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.Type: GrantFiled: August 11, 2015Date of Patent: February 20, 2018Assignee: View, Inc.Inventors: Yashraj Bhatnagar, Trevor Frank, Fabian Strong, Sridhar Kailasam, Robert Babcock, Ronald M. Parker, Robert T. Rozbicki

Publication number: 20170327940Abstract: 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: August 3, 2017Publication date: November 16, 2017Inventors: Martin John Neumann, Que Anh Song Nguyen, Disha Mehtani, Anshu A. Pradhan, Robert T. Rozbicki, Dhairya Shrivastava, Sridhar Kailasam, Trevor Frank, Jason Satern, Todd Martin

Patent number: 9429809Abstract: 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: GrantFiled: September 11, 2012Date of Patent: August 30, 2016Assignee: View, Inc.Inventors: Sridhar Kailasam, Robin Friedman, Anshu Pradhan, Robert T.
