A force sensitive scale and dual sensor load cells for use therewith isolate, measure, and reject out residual rejected effects from the output of the scale. By isolating residual rejected effects, the overall accuracy of the scale may be improved, and the scale may be made substantially insensitive to the position of an object on the scale. In addition, where a scale includes multiple load cells coupled in parallel to a load receiving member and spaced apart in the direction of the force vector, the outputs of the load cells may be effectively scaled to cancel out frictional effects inherent in the scale.

Force sensitive scale and dual load sensor cell for use therewith

A multi-load cell force sensing apparatus includes a plurality of load cells supporting an operating surface and a controller which determines the position, as well as the magnitude, of an applied force relative to the operating surface. Impulse forces may be distinguished from static forces, thereby enabling the apparatus to function as a user input device whereby a user may request the apparatus to perform functions by pressing or touching a specified location on the operating surface.
