Patent ID: 7013233

Claim:
A method for detecting the motion of an element relative to a sensor device, in which signals ( 7 to 15 ) are evaluated as a function of a pulse generator ( 1 ) that is moved past the sensor ( 3 , 4 , 5 ), characterized in that the signals ( 7 , 8 ; 10 , 11 ; 13 , 14 ) of two sensor elements ( 4 , 5 ) disposed next to each other in the movement direction are evaluated, wherein in order to detect vibrations perpendicular to the movement direction, the phase responses of the signals ( 7 , 8 ; 10 , 11 ; 13 , 14 ) of the individual sensor elements ( 4 , 5 ) and of the differential signals ( 9 ; 12 ; 15 ) of the individual sensor elements ( 4 , 5 ) are evaluated as to whether there is a phase shift in the same direction for all three measured signals ( 7 to 15 ).
