Abstract
An information sensing system as used in sensing unbalanced forces acting upon a rotating wheel being balanced is characterized by means for generating a correction factor associated with each wheel balancing operation and determined by feeding a known signal through a given circuit and comparing the output received with the output expected. The correction factor can then be applied to the sensed signals fed through the same circuit. The frequency of the known signal and other signals are both derived from the same source such as the rate of rotation of the wheel.
