Publication number: 20150029573Abstract: One object of the present invention is to provide an electrochromic device having improved insulating film structure to reduce electrical leakage. The improved structure includes a lower conductive layer, upper transparent conductive layer, an electrochromic electrode layer, a counter electrode layer, and at least one ion-conductor layer sandwiched between the electrochromic electrode layer and the counter electrode layer. The lower transport conductive layer is scribed and the gap formed from the scribing is filled with the layer(s) formed above the lower conductive layer, such as the electrode layer formed directly above the lower conductive layer. The effective linewidth of the scribe is greater than the migration length of the lithium ions intercalated into the electrode layer, such that the electrode materials occupying the gap do not convert the electrode layer into an electrically conductive region.Type: ApplicationFiled: July 25, 2013Publication date: January 29, 2015Applicant: SAGE ELECTROCHROMICS, INC.Inventors: Mark Samuel Burdis, Jean-Christophe Giron

Publication number: 20150002919Abstract: 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.Type: ApplicationFiled: June 28, 2013Publication date: January 1, 2015Inventors: Gordon Jack, Anshu Pradhan

Publication number: 20150002768Abstract: A system for controlling switchable glass based upon intention detection. The system includes a sensor for providing information relating to a posture of a person detected by the sensor, a processor, and switchable glass capable of being switched between transparent and opaque states. The processor is configured to receive the information from the sensor and process the received information in order to determine if an event occurred. This processing includes determining whether the posture of the person indicates a particular intention, such as attempting to take a photo. If the event occurred, the processor is configured to control the state of the switchable glass by switching it to an opaque state to prevent the photo-taking of an object, such as artwork, behind the switchable glass.Type: ApplicationFiled: June 26, 2013Publication date: January 1, 2015Inventor: SHUGUANG WU

Publication number: 20140362430Abstract: A driver for an electrochromic element is configured to adjust the transmittance of a solution-type electrochromic element to allow the element to display a tone. The element has a pair of electrodes and at least one organic electrochromic material mixed between the electrodes. The driver has an adjusting controller configured to adjust the transmittance of the element. The adjusting controller has controller A and controller B. Controller A is configured to saturate a change in the transmittance of the element to an initial state by applying the voltage which resets the element to the initial state. Controller B is configured to control the tone of the element by applying the voltage which adjusts the transmittance of the element following controller A.Type: ApplicationFiled: June 4, 2014Publication date: December 11, 2014Inventors: Jun Yamamoto, Shinjiro Okada
