Abstract: A sensor system and an update server perform a method for updating the sensor system. The update server performs 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. On the other hand, the sensor system performs 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: Systems and methods for designing receiving coils of an inductive position sensor are described. A processor may receive input data indicating a shape of a target of the inductive position sensor. The processor may identify an overlapping region between the target and a transmitting coil of the inductive position sensor. The processor may determine a shape of a receiving coil cell based on the identified overlapping region. The processor may generate a model of the receiving coils of the inductive position sensor based on the shape of the receiving coil cell.
