  • Patent number: 4788384
    Abstract: Electrodes are placed at the periphery of a resistive surface to pick up a current generated at a point on the resistive surface. Each electrode is connected to at least three summing lines via respective resistors each having a fixed resistance value which is predetermined as a function of the summing line and of the electrode in such a manner as to obtain analog signals from at least two of the summing lines which are linear functions of respective co-ordinates (with respect to a predetermined co-ordinate system) of a point on the resistive surface at which current is generated.
