Patent number: 8213074Abstract: 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.Type: GrantFiled: March 16, 2011Date of Patent: July 3, 2012Assignee: Soladigm, Inc.Inventors: Dhairya Shrivastava, Anshu Pradhan, Stephen C.

Patent number: 7375871Abstract: A light control system having a full range of dimming for smart-glass by providing an interface between an off-the-shelf dimmer and a electrochromic glass device is disclosed herein. The light control system or electrochromic glass control device acts as an interface that converts an asymmetric alternating current (AC) power signal from the dimmer device into a symmetric, amplitude controlled AC output signal for controlling the tint of the smart-glass device. The electrochromic glass control device includes a powerline interface circuit that receives the asymmetric AC power signal from the dimmer. A controller connects to the powerline interface circuit to generate a control signal responsive to the asymmetric AC power signal. Connecting between the dimmer and the controller, an output stage generates the symmetrical AC output signal responsive to the control signal to control the electrochromic glass device.Type: GrantFiled: October 27, 2005Date of Patent: May 20, 2008Assignee: Leviton Manufacturing Co., Inc.Inventors: John Libretto, Michael Ostrovsky, Eugene Frid, Edward Uftring
