  • Patent number: 7132625
    Abstract: 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.

  • Patent number: 7102102
    Abstract: A heater assembly heats media substrate in a printing system prior to imprinting a desired image on the substrate. A plate member engages the substrate and communicates thermal energy thereto for the heating. A laminar assembly is adhered to the plate member and includes a trace pattern for converting electrical energy to the thermal energy. A thermal storage member is interposed between the plate member and the trace pattern for distributing thermal energy throughout the thermal storage member. Two thermal fuses are serially connected, one at each end of the trace pattern and disposed relative to the thermal storage member for detecting an undesired temperature increase in the laminar assembly sufficient for opening the fuses and electrically isolating the heater assembly against a consequential thermal run-away causing insulation degradation and an electrical short between the trace pattern and the plate member.

  • Patent number: 7075042
    Abstract: A solid state heater uses a heater subassembly employing a terminal block, terminals and a PTCR or NTCR heater. The terminals engage and make electrical contact with the heater, thus eliminating the need for a rigid heater housing. The heater subassembly can be formed into a soft body or rigid body heater for heating purposes. The soft body heater uses a soft casing that envelops the heater subassembly with the casing expanding upon heating to provide a snug fit during use. The heater subassembly can be inserted in the cavity of either a soft body or a rigid body with potting compound filling any remaining voids, and the rigid or soft body can then be used for heating purposes.

An in situ reconfigurable circuit comprises the heat-activated electrical coupling, a fusible link, a primary circuit and a secondary or back-up circuit. An in situ recoverable electrostatic discharge (ESD) circuit comprises the heat-activated electrical coupling, a primary ESD protection portion, and a secondary or back-up ESD protection portion. A method of in situ reconfiguring a circuit comprises creating the heat-activated electrical coupling and activating the electrical coupling with heat.

  • Publication number: 20040173602
    Abstract: An apparatus for operably connecting an electrical source to a conductive coating or film. The apparatus may include a substrate made of a structural material. A conductive coating or thin film may be applied to the substrate. An interface layer may be applied over the conductive coating and conduct electricity thereto while transferring insufficient force to separate the conductive coating from the substrate. A conductor, for providing electricity to the interface layer comprising strands configured to be separable and electrically conductive, may be positioned in contact with the interface layer. A clamping mechanism may apply a clamping load urging the conductor toward the conductive coating. The strands of the conductor may be formed to distribute mechanical stress and strain induced by thermal expansion and the clamping load sufficiently to substantially reduce damage to the mechanical and electrical integrity of the conductive coating.
