ABSTRACT:
Arrays of electrostatic elements arranged in columns and rows are used for switching purposes and for memory devices. Electrostatically attracted members, for each element, when actuated, complete a capacitance device to render that element capable of retaining a charge. Whether or not the element is a capacitance device is sensed by a high frequency signal. Permanent memories can be made by substitution of a pattern of conductor areas for the attractable members. The attractable members, when attracted, form a capacitance switching device or matrix of switches.
