A floating seat may have at least one seat shell with a seat surface region and a backrest region. The seat may also have a base element on which the seat shell is arranged in an adjustable manner, and an adjustment mechanism for adjusting the seat shell relative to the base element and/or a seat base. The adjustment mechanism has at least one adjustment unit for adjusting the seat shell and at least one drive unit which is designed to lock the base element and the seat shell in place in a self-locking manner. The lock can be released by a force introduced into the adjustment unit by an occupant sitting in the seat shell via said seat shell as well as by a force introduced into the adjustment unit by the drive unit.

A system for detecting the absolute rotational angle of a shaft rotatable more than one revolution includes a drive wheel connected to the shaft to rotate therewith. The drive wheel includes measurement sectors adjacent to one another in a circumferential direction. First and second driven wheels are engaged to the drive wheel. First and second sensors monitor rotational positions of the driven wheels to thereby detect an absolute rotational angle of the shaft. A third sensor monitors a relative angular position of the shaft in relation to a detected one of the measurement sectors to thereby detect the relative angular position of the shaft within one revolution of the shaft. The detected absolute rotational angle of the shaft is refined with the detected relative angular position of the shaft to thereby generate the absolute rotational angle of the shaft with more precision.

An operator control system includes switches, RFID transponders, and a RFID reader. Each switch has a cap support and a switch cap. The switch caps are respectively interchangeably attachable to the cap supports. The RFID transponders are respectively attached to the switch caps. Each RFID transponder stores a respective piece of information identifying a respective control function so that the switch cap to which the RFID transponder is attached is associated with the respective control function. The RFID reader is arranged on at least one of the switches for reading the piece of information of at least one of the RFID transponders.

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.

Angle sensor

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.

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.

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.

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.

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.

A method for determining the absolute angular position of a motor vehicle steering wheel includes using a sensor to continually detect first angular measured values of the steering wheel at a constant first interval. A controller outputs encoded output values based on the detected first angle measured values. At high steering wheel rotational speeds the difference between two consecutively measured angular values becomes increasingly greater as a result of the constant measuring rate of the first interval. At such high rotational steering wheel speeds, the method achieves a reliable angular measurement which is verifiable by plausibility considerations by detecting at least one additional second angular measured value of the steering wheel for each output value. The additional second angular measured is detected at a second interval shorter than the first interval and lying between the detection times of successive first angular measured values.
