Abstract: A position sensor system includes a magnetic source and a sensor device movable relative to the magnetic source. The magnetic source has a first track of alternating magnetic poles, and a second track of an equal number of alternating poles, but 180° phase shifted relative to the first track. The sensor device is configured for measuring a plurality of magnetic field components, including a first magnetic field component at a first sensor location facing the first track, and a second magnetic field component oriented parallel to the first magnetic field component at a second sensor location facing the second track, and for deriving a first and a second difference signal from the plurality of magnetic field components, and for determining a position based on these difference signals.

Abstract: The present invention relates to a method for determining at least one motion parameter of a freely-guided electronic device on a substrate, such as the velocity of the movement of the freely-guided electronic device, comprising: determining a measurement of a vibration signal, which is generated by the interaction between the freely-guided electronic device and the substrate, and a determination of the motion parameter of the freely-guided electronic device from the measured vibration signal of the freely-guided electronic device.
