Abrégé
A method, equation, system, and device for electrically heating Indium Tin Oxide (ITO) and other transparent conductive materials having a uniform sheet resistivity for defogging and de-icing in a cold environment. The use of nonparallel busbars for connecting the conductive materials reduces excessive and dangerous hot zones. The mathematical analysis and equations provide a means of precisely providing an intermittent electrical connection so that the Watt density and heating is uniform, allowing much higher temperature for de-icing and defogging and more efficient use of energy. This same concept can be used for three dimensional formed heaters to compensate for non uniform sheet resistivity. Also shown are a means of improved busbar designs and an equation and a means of altering sheet resistivity to produce electric heaters with non parallel busbars of various shapes for uniform heating
Classes IPC ?
