摘要： A sensor detects the rotation of a component (object) of a vehicle in a non-contact manner, and generates a differential signal according to the rotation. Two comparators have different hysteresis characteristics. At both edges of one signal that is an output of one of the comparators, if a signal of the other comparator is not at the same level, it is determined that a distance (gap) between an object and the sensor is within a predetermined range in which the differential signal is effective.

摘要： A variable-reluctance magnetic detection head delivers an electrical signal (Uin) and a rising wavefront of the electrical signal is compared with a first threshold (Th) in order to switch from a first state (B0) to a second state (B1), and a falling wavefront is compared with a second threshold (Tb) lower than the first threshold (Th) in order to switch from the second state (B1) to the first state (B0). In a diagnostics step, the first threshold (Th) or the second threshold (Tb) is modified, bringing these thresholds closer together, and a magnetic detection head is diagnosed as being defective if the duty cycle of the second state (B1) is modified during the diagnostics step by a value higher than a diagnostics threshold predetermined in relation to a reference level.

摘要： A linear position measuring system and a method for determining an absolute position of a carriage along a slide rail are disclosed. An analog signal progression (S) based at on at least one reference point is here discretely scanned in response to a first threshold (SW1) and second threshold (SW2). The resultant digital values are stored in a first measured value register (MR1) and a second measured value register (MR2). The contents of the first and second measured value register (MR1, MR2) are compared with the respective contents of a first and second set measured value register. The reference point is output as an ideal reference point if the differential value lies within a predetermined tolerance range, and is otherwise discarded.

摘要： A digital electronic length or angle measuring instrument includes an arrangement for error correction. A signal generator delivers periodic analog reference signals R.sub.S1, R.sub.S2 which are compared in a comparator with scanning signals S.sub.1, S.sub.2 generated by the measuring instrument. In accordance with the result of the comparison in the comparator, the reference signals R.sub.S1, R.sub.S2 are altered as a function of correction data for symmetry, amplitude ratio, phase angle, and signal form, which correction data are determined in a correction component and are supplied to setting members included in the signal generator. In this way, an in dependence on the correction data, improved reference signals are generated which then form a basis for the next comparison in the comparator.
