Abstract

1431754 Windscreen heater TARKA CONTROLS Ltd 16 May 1973 [18 May 1972 27 Oct 1972 6 Feb 1973] 23541/72 49726/72 and 5736/73 Heading H5H [Also in Divisions H2 and G1] A system for reducing condensation on the interior surface of a vehicle rear window 1 comprises spaced electrodes 3, 4 adapted to be bridged resistively by condensation on the surface, an electronic switching circuit responsive to the resistance between the electrodes and a heater 11 responsive to the state of the switching circuit. When condensation appears on the window, the resistance between the electrodes 3, 4 decreases, causing the electronic switching circuit to connect the heater to the vehicle power supply. One of the electrodes is curved so that the spacing of the electrodes is reduced in the centre of the window, thereby increasing the sensitivity of the system to condensation in the central area of the window. The heater and the electrodes are preferably formed by material deposition on the window.
