Publication number: 20130032584Abstract: A defogger system includes structure defining a window or a mirror, a heating element operatively connected to the structure to selectively apply heat to the structure, and a source of electrical energy. The defogger system also includes a switch and an electrically conductive path from the source of electrical energy to the heating element. The switch includes an active material member, and is configured such that the switch interrupts the electrically conductive path when the active material member is above a predetermined temperature. The switch is also configured such that the switch does not interrupt the electrically conductive path when the active material member is below the predetermined temperature.Type: ApplicationFiled: August 5, 2011Publication date: February 7, 2013Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Nicholas W. Pinto, IV, Paul W. Alexander, Nancy L. Johnson

Patent number: 8299400Abstract: A heatable vehicle window (e.g., windshield or backlite) has bus bars electrically connected to a heatable coating having one or more heatable conductive layers. Electrical connection(s) between at least one bus bar and a corresponding external connector in the heatable window is/are made using a silver inclusive epoxy. The use of the silver inclusive epoxy permits a thin substantially uniform electrical connection to be made and permits numerous example advantages to be realized.Type: GrantFiled: August 4, 2005Date of Patent: October 30, 2012Assignee: Guardian Industries Corp.Inventors: Daniel F. Prone, Matthew Zabiega
