ABSTRACT:
A compact electronic weighing scale whose major dimension is not substantially greater than the width of an average adult shoe and comprises a capacitive load cell adapted to be acted upon by an annular load transmission element coupled to the weighing platform. The capacitive load cell and the load transmission element are so dimensioned that the change in capacitance of the load cell in response to a load acting upon the weighing platform is substantially uniform regardless of the point of application of the load on the weighing platform.
