Patent number: 7285748Abstract: The heating device includes a conductive layer which is positioned on an electrically insulative substrate. Preferably, the conductive layer is screen printed onto the substrate. The substrate is designed to limit elongation of the conductive layer, thereby improving the durability of the conductor and enabling the heating device to be used in flexible applications, such as automobile seats. The substrate can include at least one aperture passing therethough to further improve flexibility, fatigue resistance, and breathability of the heater. The conductive layer is configured to include a buss structure with a first buss ground inwardly adjacent from the periphery of the heating device and a first buss with serpentine paths extending from one edge of the heating device to another edge. The buss structure further includes a second buss with L-shaped portions positioned between the serpentine paths and the first buss ground. The second buss ground is located in a central location between the serpentine paths.Type: GrantFiled: December 21, 2004Date of Patent: October 23, 2007Assignee: Illinois Tool Works Inc.Inventors: James P. Nelson, Tilak R. Varma, Michael Starozhitsky, Paul J. Storiz, Edward Bulgajewski

Publication number: 20060245202Abstract: The present invention is directed to a system for reducing condensation on the inner surface of a vehicle light cover, and preventing or deicing ice build up on the exterior of the cover. In an embodiment, a heater is mounted to a carrier and the heat produced by the heater prevents the occurrence of condensation on the inner surface of the light cover or build up of ice on the outer surface. In an embodiment, one or more vents may be provided in the carrier and one or more corresponding holes may be provided in the heater so as to increase the flow of air across the inner surface of the light cover. A controller may be provided to control activation of the heater.Type: ApplicationFiled: April 28, 2005Publication date: November 2, 2006Inventors: Cary Moreth, Edward Bulgajewski, Erik Arnold

Patent number: 6307188Abstract: The heater is formed from a substrate layer, a feeder buss layer, a dielectric layer, a PTF (polymer thick film) conductor or main buss layer, a PTC (positive temperature coefficient) thermistor layer and an external laminated adhesive layer. All of the layers are substantially coextensive. The feeder buss layer, dielectric layer, main buss layer and PTC thermistor layers are preferably screen printed or otherwise selectively applied. The feeder buss layer includes first and second external electrical terminals formed on a single side thereof, and a buss for providing electrical communication from the first terminal to a connector diagonally removed from the second terminal. The connector and the second terminal provide electrical communication to diagonally opposed corners of the PTF conductor or main buss layer thereby providing relatively uniform current path distances through the thermistor layer.Type: GrantFiled: May 25, 2000Date of Patent: October 23, 2001Assignee: Illinois Tool Works Inc.Inventor: Edward Bulgajewski
