  • Device for providing a circuit with resistive and capacitive characteristics where the resistive characteristic is controllable by electromagnetic radiation
    Patent number: H525
    Abstract: A dielectric body composed of mercuric iodide is placed between and in contact with two capacitor plates. Electrical conductivity of mercuric iodide increases with the intensity of light on the dielectric body. The dielectric body then forms a resistive path between the two capacitor plates. The two plates and the dielectric body therefore form the circuit equivalent of a capacitor in parallel with a resistor, where the resistance of the resistor is that of the dielectric body. The resistance of the body may be controlled by controlling the intensity of incident light. Charges on the capacitor plates may be discharged by illuminating the body with light of adequate intensity.
