Abstract
Multi-component motions between two parts are sensed by this apparatus which comprises a first conductive element and a plurality of second conductive elements with a frame connected to the first and second elements to hold them closely spaced from each other but not in electrical contact. An electric oscillator is connected between the first element and the second elements to apply an oscillating signal between the first element and each of the second elements. A sensing circuit is connected to each of the second elements to separately detect changes in the protential between the first element and each of the second elements as the two parts are moved relative to each other and to produce a first set of separate electrical signals representative of such changes in the potential. These signals are then algebraicly combined in a plurality of predetermined combinations to thereby generate a second set of electrical signals which are each representative of the separate linear and rotative orthogonal components of the relative motion between the two parts.
