    摘要: A method for correcting a characteristic curve having values corresponding to displacement between a magnetic sensor element and a magnetic ruler of a sensor within a displacement range includes determining whether the characteristic curve has a jump discontinuity by comparing a first value at a first range end to a second value at a second range end and by comparing values between the range ends. Upon determining that the characteristic curve has a jump discontinuity, the method further includes determining the magnitude of the jump discontinuity, defining a decision threshold lying between the first and second values, identifying the values within the range which are lower than the decision threshold, and offsetting the identified values by the magnitude of the jump discontinuity such that the characteristic curve is corrected to eliminate the jump discontinuity, whereby subsequent measurements made by the MR sensor take into account the jump discontinuity magnitude offset.

    摘要: An electric circuit arrangement and method for checking intactness of both a photodiode array and an electrical connection between an array output and a microprocessor input. The array output has a high resistance when the array is inactive and intact. In case of array error, the array output is connected via in each case a defined internal resistance to ground and supply voltages. The circuit arrangement enables at any time an assessment of the status of the connection and, if the connection is intact, enables an assessment of array intactness. This is achieved by connecting the array output via a first test resistor arranged in the spatial vicinity of the array to the ground voltage and by connecting the microprocessor input via a second test resistor arranged in the spatial vicinity of the microprocessor to a microprocessor port output which can be connected either to the ground or supply voltages.

    摘要: A method for evaluating a code signal generated by an encoder having code and reference tracks. The encoder is interposed between a light and a light sensor and moves relative to the light and the sensor such that the code and reference tracks transmit light from the light onto the sensor. The sensor generates the code signal as a function of the light transmitted by the code track which is received by sensor transducers. The method includes capturing and evaluating the amplitude of a reference signal generated as a function of the light transmitted by the reference track which is received by sensor transducers. A measurement parameter relevant for evaluating the amplitude of the code signal is then adapted on the basis of the evaluation of the amplitude of the reference signal in order to compensate the evaluation of the code signal to changing measurement conditions.

    摘要: A method for evaluating a signal generated by a position measuring system having an encoder with a code track. The encoder is interposed between a light source and a light sensor and moves relative to the light source and the sensor such that the code track transmits light from the light source onto the sensor. The light sensor generates the signal as a function of the light received by transducers of the sensor. The method includes determining brightness of a code track signal generated by sensor transducers assigned to a code track of the encoder and determining brightness of a non-code track signal generated by sensor transducers assigned to a non-code track of the encoder. The sensor transducers assigned to the code track of the encoder are then determined as being exposed to the light source as a function of the relative brightness between the code and non-code track signals.

    摘要: An angle sensor includes two measuring pinions which rotate in the same direction in response to a drive pinion rotating. The measuring pinions have different absolute angular positions after rotating. The absolute angular position of the drive pinion is determinable from the absolute angular positions of the measuring pinions. A delta wheel between the measuring pinions has two coaxially arranged rings. One ring engages the second measuring pinion and the other ring engages the first measuring pinion such that the rings rotate relative to one another in the same direction in response to the measuring pinions rotating in the opposite direction. A spring connecting the rings together biases the rings to move in opposite directions toward one another after the rings have been rotated relative to one another in the same direction such that the rings respectively press the measuring pinions against the drive pinion.

    摘要: A sensor determines the absolute angular position of a body that can rotate through rotations. The sensor includes two code wheels which rotate as the body rotates. The code wheels are driven at a different gear ratio such that the code wheels rotate faster than the body and the code wheels rotate at different rates. Two sensor elements respectively determine the rotational angle positions of the code wheels. The difference between the rotational angle positions is a beat angle. The different gear ratio is selected such that beat angle periods are in an angular measuring range of the sensor and the absolute angular positions of the code wheels in the beat angle periods is different. The absolute angular positions of the code wheels in successive beat angle periods is offset by the nth part of the measuring range of a sensor element, where n is number of beat angle periods.
