Abstract
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.
