1. An apparatus for sensing the relative rotational position between first and second relatively rotatable members, comprising:

  • a transmitter disk having a planar surface and being mountable to said first member so that said planar surface of said transmitter disk is substantially perpendicular the an axis of rotation of the first and second members, said transmitter disk having a conductive material mounted to said planar surface and patterned in the form of a circle having a sinusoidally modified diameter; and

    a receiving disk having a planar surface and being mountable to said second member so that said planar surface of said receiving disk is substantially perpendicular the an axis of rotation of the first and second members, said receiving disk having a conductive material mounted thereon and arranged in a pattern so as to receive a signal from said transmitter disk and output a signal indicative of the relative rotational position of the first and second members.
