Abstract: An inductive position sensor for detecting a linear or angular movement of a conductive target, including: a transmitter coil; a first receiver coil and a second receiver coil, wherein the first receiver coil and the second receiver coil have a linear or angular shape and define the detection range of the inductive linear or arc position sensor; a first conductive target and a second conductive target; the first conductive target and the second conductive target each have a linear or angular shape extension of half the detection range of the inductive position sensor and are spaced from each other by half the detection range of the inductive position sensor.

Abstract: A method for updating a sensor system, the method including: performing at an update server side the steps of: retrieving a pre-shared sensor key associated with the sensor system, calculating a server signature based on update data and the retrieved sensor key, and transmitting the update data and the calculated server signature to the sensor system; and performing at the sensor system the steps of: receiving the update data and the calculated server signature, retrieving the pre-shared sensor key stored in a register, calculating a sensor system signature based on the update data and the pre-shared sensor key, comparing the sensor system signature with the server signature and processing the update data if the sensor system signature and the server signature are identical.

Abstract: A method for calibrating a linearization function for correcting an output of a position sensor providing a continuous output position signal is described. The method adds a new linearization point to the linearization function by detecting the maximum error at the output of the position sensor and applying the new linearization function to the output of the position sensor and repeat the adding new linearization points until all available linearization points have been defined.
