1. An apparatus comprising:

  • a rotating element;

    a linearly moving element;

    a rotary to linear converter coupled to the rotating element and the linearly moving element, wherein the rotary to linear converter translates linear movement of the linearly moving element to rotary movement of the rotating element;

    means for determining relative movement of the rotating element;

    first and second grooves in the linearly moving element, the first and second grooves separated azimuthally by a predetermined angle greater than zero and vertically by a predetermined distance;

    first and second sensors separated azimuthally by the predetermined angle wherein the first sensor responds to proximity of the first groove and the second sensor responds to proximity of the second groove, wherein the first and second sensors are coupled in a bridge comprising means for providing an output signal having (a) a first state when neither the first nor the second groove is proximate to either the first or the second sensor, (b) a second state when the first groove is proximate to the first sensor, and (c) a third state when the second groove is proximate to the second sensor.
