Publication number: 20240118578Abstract: 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. 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: October 19, 2023Publication date: April 11, 2024Inventors: Gordon Jack, Sridhar K. Kailasam, Stephen C. Brown, Anshu A. Pradhan

Publication number: 20240103332Abstract: This disclosure provides systems, methods, and apparatus for controlling transitions in an optically switchable device. In one aspect, a controller for a tintable window may include a processor, an input for receiving output signals from sensors, and instructions for causing the processor to determine a level of tint of the tintable window, and an output for controlling the level of tint in the tintable window. The instructions may include a relationship between the received output signals and the level of tint, with the relationship employing output signals from an exterior photosensor, an interior photosensor, an occupancy sensor, an exterior temperature sensor, and a transmissivity sensor. In some instances, the controller may receive output signals over a network and/or be interfaced with a network, and in some instances, the controller may be a standalone controller that is not interfaced with a network.Type: ApplicationFiled: October 13, 2023Publication date: March 28, 2024Inventors: Stephen C. Brown, Deepika Khowal, Namrata Vora

Patent number: 11940705Abstract: A method of controlling tint of a tintable window to account for occupant comfort in a room of a building. The tintable window is between the interior and exterior of the building. The method predicts a tint level for the tintable window at a future time based on a penetration depth of direct sunlight through the tintable window into the room at the future time and space type in the room. The method also provides instructions over a network to transition tint of the tintable window to the tint level.Type: GrantFiled: June 30, 2021Date of Patent: March 26, 2024Assignee: View, Inc.Inventors: Stephen C. Brown, Deepika Khowal, Namrata Vora, Santosh V. Philip

Patent number: 11927866Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations. Also described are self-meshing networks for electrochromic windows.Type: GrantFiled: December 18, 2020Date of Patent: March 12, 2024Assignee: View, Inc.Inventors: Stephen C. Brown, Dhairya Shrivastava, Erich R. Klawuhn, Trevor Frank, Douglas Silkwood

Patent number: 11445025Abstract: Software applications are used for controlling the optical state of one or more optically switchable windows or other optical products installed in a structure such as building. The applications permit users to send and/or receive data and/or commands for controlling the switchable optical products. In some embodiments, the applications provide an interface with a window network controller, which directly or indirectly controls windows in a structure. Relevant processing involving the application may include user authentication, commissioning, adaptive control, and decisions on whether to permit an action or change requested by a user. In some embodiments, the application allows users to directly control the tint state of one or more tintable windows. In some embodiments, the application allows users to change a rule or property associated with controlling a switchable optical product.Type: GrantFiled: July 31, 2019Date of Patent: September 13, 2022Assignee: View, Inc.Inventors: Dhairya Shrivastava, Todd Marques, Stephen C.
