  • Patent number: 4951764
    Abstract: An improved digital display scale of the type with a load receiver acting on an arrangement of two parallel leaf springs which are movable relative to a base member, in which the leaf springs, a mounting support on the base and a load receiver supporting structure together form a parallelogram, and a capacitor with a pair of closely spaced capacitor plates the spacing between which changes under load to change capacitance and thereby serve as an indicator of load. One of the two capacitor plates is between the leaf springs and connected to the mounting support through an insulating piece. The other capacitor is formed by one of the leaf springs. Various preferred embodiments are also disclosed and claimed.
