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.

Abstract: An adjusting mechanism is disclosed for adjusting a digital indicator of an electronic mechanism, such as a timepiece, which includes a first pulse generating mechanism for normally operating the digital display indicator. A second pulse generator includes a pulse former connected electrically to the digital indicator for supplying electrical adjusting pulses thereto. A sensor is operably connected to the pulse former to deliver activating signals thereto for the production of an adjusting pulse. A pulse control member is operably associated with the sensor to control the delivery of activating signals to the pulse former. Either the sensor or the pulse control member is rotatable relative to the other such that activating signals are generated in response to such relative rotation and are generated at a rate which is proportional to the rotational speed of the pulse control member.
