Abstract:
Apparatus for sensing rotation comprising:a housing;a resonator attached to the housing;a first set of electrodes consisting of one or more electrodes, the first set of electrodes being attached to either the resonator or the housing;a second set of N electrodes numbered from 1 to N attached around the circumference of either (1) the housing if the first set of electrodes is attached to the resonator or (2) the resonator if the first set of electrodes is attached to the housing, the n'th electrode being attached at angular position .theta..sub.n with respect to a reference point on the resonator, n taking on integer values between 1 and N, the second set of electrodes opposing the first set of electrodes, the second set of electrodes being spaced non-uniformly around the circumference for N equal to 4, 8, or 16.
