Abstract: An inductive position measuring system includes metallic target and a flexible substrate having a first field coil and a first receiving coil arrangement, the first field coil and the first receiving coil arrangement each running along in a straight line on the flexible substrate. The metallic target is at a distance from the flexible substrate and is configured to provide an inductive coupling between the first field coil and the first receiving coil arrangement, the actual position of the metallic target being able to be determined based on this inductive coupling. The metallic target moves relative to the flexible substrate, with the metallic target being able to be deflected along a coordinate line on a curved path. The flexible substrate is curved such that the first field coil running and the first receiving coil arrangement are likewise curved and extend parallel to the coordinate line.

Abstract: Described herein is a magnetic-field-based position determination device including a sensor device with at least two magnetic field sensors arranged spaced apart from each other by a distance and with a magnet movable relative to the sensor device. Each of the two magnetic field sensors is configured to measure the magnetic field emanating from the magnet in at least a first spatial direction and a different second spatial direction and, based thereon, to determine a magnetic field vector angle, respectively, wherein the first magnetic field sensor determines a first magnetic field vector angle, and wherein the second magnetic field sensor determines a second magnetic field vector angle. The sensor device is configured to determine the current position of the magnet relative to the sensor device based on the determined magnetic field vector angles and the distance of the two magnetic field sensors from each other.

Abstract: Implementations relate to a sensor assembly for determining rotation about an axis and linear movement parallel to the axis. The sensor assembly comprises a magnetic structure comprising a north pole radially displaced from the axis and a south pole radially displaced from the axis and opposite to the north pole. The north pole and the south pole of the magnet extend radially into the direction of the axis at an axial end of the sensor assembly. The sensor assembly further comprises at least one sensor element sensitive to magnetic fields radially between the north pole and the south pole.

Abstract: A method for determining a rotation angle of a magnet includes measuring a 3D magnetic field vector of a magnetic field generated by the magnet, wherein the 3D magnetic field vector describes at least a part of an ellipse in 3D space during a rotational movement of the magnet. The method further includes mapping the measured 3D magnetic field vector to a 2D vector based on a compensation mapping, wherein the compensation mapping is configured to map the ellipse in 3D space to a circle in 2D space. The method further includes determining the rotation angle of the magnet based on the 2D vector.

Abstract: A control stick may include a magnet and a three-dimensional (3D) magnetic sensor. The 3D magnetic sensor may determine a twist angle of a handle of the control stick based on a strength of a magnetic field at the 3D magnetic sensor. A twisting of the handle may modify an air gap between the 3D magnetic sensor and the magnet. The strength of the magnetic field may be based on strengths of first, second, and third magnetic field components. The 3D magnetic sensor may determine a tilt angle of the handle based on a ratio of the strength of the first magnetic field component to the strength of the third magnetic field component. A tilting of the handle in a direction corresponding to the first magnetic field component may modify the ratio of the strength of the first magnetic field component to the strength of the third magnetic field component.
