Patent number: 11482147Abstract: The embodiments herein relate to methods for controlling an optical transition and the ending tint state of an optically switchable device, and optically switchable devices configured to perform such methods. In various embodiments, non-optical (e.g., electrical) feedback is used to help control an optical transition. The feedback may be used for a number of different purposes. In many implementations, the feedback is used to control an ongoing optical transition. In some embodiments a transfer function is used calibrate optical drive parameters to control the tinting state of optically switching devices.Type: GrantFiled: April 19, 2017Date of Patent: October 25, 2022Assignee: View, Inc.Inventors: Anshu A.

Publication number: 20220032584Abstract: Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU's) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.Type: ApplicationFiled: June 11, 2021Publication date: February 3, 2022Applicant: View, Inc.Inventors: Ronald M.
