Abstract:
A windshield wiper park position heater employs an area-type heater construction having a flexible substrate supporting a high resistance heater material between electrodes of a lower resistance electrode material. The high length-to-width of the heater element is accommodated through a bus structure that orients current flow along the shortest dimension of the heater and by supplying power at a midpoint of the bus structure to decrease voltage drop over the longest dimension of the heater. A clip structure allows internal conductive layers of laminated connection point between heater components to be simply joined in the crimping operation.
Abstract:
A resistive heating element for use in or manufacturing of a component of an aircraft or spacecraft. The resistive heating element includes a sheet made from carbon nanotubes (CNTs) having a length of at least about 5 μιη, and formed as a nonwoven or composite polymer sheet, having good uniformity. The sheet is made with a basis weight between 1 and 50 grams per square meter (gsm), to provide a resistance value, inversely related to the basis weight, of at least about 0.01 ohms per square (Ω/□), and up to about 100 Ω/□. The CNTs can have an aspect ratio of at least about 1000:1, and at least about 10,000:1 or 100,000:1. The resistance value of the sheet can be controlled by the basis weight of CNTs, the diameter of the CNTs, and the length of CNTs, as well as chemical and mechanical treatments.
Abstract:
The invention relates to glazing having a conductive coating having one or more data transmission windows for transmitting data to/from electronic devices in a vehicle, in which a deletion line surrounds the data transmission window. The deletion line defines first and second regions of the conductive coating. The first region comprises an electrically heated region and first and second busbars for supplying electrical power. The second region comprises at least one data transmission window. The second region may be electrically isolated from the second busbar so that the second region cannot be electrically heated.

A heating system comprising a packette for heating a mask, wipe or towelette. In preferred embodiments, the packette comprises printed heating elements, printed circuit elements and a means of connecting to a power source. Power may be supplied through a USB-type connector or a handheld power supply that is custom designed to work with the heating packette.
Abstract:
A heater comprises a plurality of zones with at least two zones having a variable power density gradient different from one another. The heater having zones of different variable power density gradients allows for controlling the heat output and temperature profile of the heater in one or more directions of the heater. The heater can be used, for example, to control the temperature profile in a vertical direction.

Abstract:
The invention concerns a heating element (1) for generating heat when connected to an electrical power source, comprising a substrate supporting first and second feedline (2, 2a) extending generally along opposite sides of the element (1), each feedline comprising an electrical contact point to the source, each feedline (2, 2a) distributing the power supply along it, an intermediate substrate part (3) sandwiched between the two feedlines (2, 2a) supporting a layer of resistive material, a current flowing from one feedline (2) to the other feedline (2a) in operation through the layer and dissipating heat. The layer is in the form of a pattern applied on the substrate part (3) and configured so that the sheet resistance thus locally obtained varies continuously over the intermediate substrate part (3) in correspondence to a respective predetermined sheet resistance in order to achieve a desired temperature distribution over the heating element (1).
