Patent number: 7132625Abstract: A heatable article, e.g. a heatable windshield, having a generally trapezoidal shape has a conductive member, e.g. a conductive coating, between and in contact with a pair of spaced bus bars having different lengths. Selected portions of the coating between the bus bars are segmented to reduce the difference in watt density between the coatings at the bus bars when current moves through the coating. In one non-limiting embodiment, the width of the segments at the longer bus bar is less than the width of the segments at the longer bus bar. With this configuration, the watt density at the bottom of the windshield is increased to more efficiently remove ice and snow. In another non-limiting embodiment, the coating has a communication window to pass frequencies of the electromagnetic spectrum, e.g. RF frequencies, to obtain information from within the vehicle.Type: GrantFiled: October 3, 2002Date of Patent: November 7, 2006Assignee: PPG Industries Ohio, Inc.Inventor: Charles S.

Patent number: 6942624Abstract: The input/output system of the present invention includes a sheet-like input/output unit that includes wiring and a connection box that is attached to an edge of the sheet-like input/output unit. The connection box includes a housing that is attached so as to sandwich the sheet-like input/output unit and internally encloses a circuit board that is connected to the wiring. The housing includes a slit through which the sheet-like input/output unit passes and whose upper and lower edges are curved and means for fixing the sheet-like input/output unit that is disposed inside to the slit. Since the means for fixing the sheet-like input/output unit is disposed inside to the slit, the edges of the slit are narrow but formed with large radii of curvature, so that the sheet-like input/output unit is not folded over at the slit part. The slit can also be sealed by attaching packing to the edge of the slit.Type: GrantFiled: June 25, 2003Date of Patent: September 13, 2005Assignees: GAC Corporation, Denso CorporationInventors: Shun Takizawa, Yuichi Minamiyama, Hiroto Nakatani, Kenichi Yanai
