Abstract: The invention relates to a method and to a device (1) for processing a motor signal of a direct current motor (3), in particular of an adjustment drive of a motor vehicle, wherein the armature current (la) and the motor voltage (Um) of the direct current motor (3) are detected and used for determining the counter induction voltage (E) of the direct current motor (3), by means of which a number of control signals (Sfn) having different ripple frequencies (fn) for controllable frequency filters (Fn) are generated. The current ripples (Rn) that are generated in a frequency dependent manner by the frequency filters (Fn), to which a filter input signal (If) derived from the armature current (la) and the motor voltage (Um) is applied, are synchronized with each other in the course of the ripple count.

Abstract: The invention generally pertains to monitoring of machinery, and, more particularly, measuring instantaneous angular velocity of a shaft. The invention provides a simple, easy to install, inexpensive apparatus and method of using the apparatus to monitor instantaneous (true multiple-per-rev) angular velocity or rotational speed of rotational equipment. The invention accomplishes this by using a tape having alternating reflective and non-reflective areas, the tape bonded to, for instance, a shaft. Markings on the tape define the alternating reflective and non-reflective areas. When a light source is directed at the tape, a reflected beam is created, which is detected by a light sensor. The light sensor thus generates a signal, which is used by a processor to perform calculations including instantaneous angular velocity. As described herein, formulas are presented and designed to avoid the phase shifting properties resulting from the discontinuity at the tape seam (where the ends of the tape meet). The processor further records a time of arrival of the reflected beam such that the time of arrival is combined with the signal to perform the calculations.
