  • Graphical input apparatus for electrical equipment
    Patent number: 4080514
    Abstract: Two improvements are disclosed for a known graphical input tablet employing a resistive sheet stretched across, but spaced from, a resistive member, wherein the co-ordinates of a point are indicated by pressing the sheet into contact with the member at the point: firstly the resolution of the tablet is increased by the addition of conducting strips dividing the sheet and/or the member into regions, and a circuit for indicating in which region the contact occurs; and secondly by the addition of a circuit for indicating when two such contacts are made at the same time.
