ABSTRACT:
An electro-mechanical pulse generator for producing electronic pulses to set or correct the readout of an electronic digital display. Two contact assemblies rotatable relative to one another cooperate to close at least two pairs of electric contact elements to produce at least two pulses. The pulses have a phase shift relative to one another which is dependent upon the direction of relative rotation of the contact assemblies and a frequency which is proportional to the speed of rotation. Control logic determines the phase shift of one pulse relative to another, i.e. lead or lag, and causes an UP-DOWN counter to produce an up-count or down-count accordingly.
