Abstract: A sine wave oscillator for an inductive sensor system is disclosed. The sine wave oscillator comprises a decoupler and a low-pass filter, wherein the decoupler is configured to provide a pulse width modulated signal as a decoupled signal at one output of the decoupler. One input of the low-pass filter is connected to the output of the decoupler. The low-pass filter is configured to provide a sinusoidal signal for the inductive sensor system by using the inverted signal at an output of the low-pass filter. The sine wave oscillator further comprises a microcontroller that is designed to provide the pulse width modulated signal with a predetermined frequency and a predetermined duty cycle at one pin of the microcontroller.

Abstract: Sensor for detecting a position in two spatial directions (x, y), wherein the sensor comprises a sensor array and an actuator. The sensor array has a first row and at least a second row. The rows have in a first spatial direction (x) adjacently arranged sensor elements. The rows are arranged side by side in a second spatial direction (y) transverse to the first spatial direction (x). The actuator is arranged in a third spatial direction (z) transverse to the first spatial direction (x) and the second spatial direction (y) spaced apart from the sensor array. The actuator is designed movable in the first spatial direction (x) and the second spatial direction (y) relative to the sensor array. The actuator is adapted to influence a measurement variable of the sensor elements, wherein a signal of a sensor element represents a degree of overlap of the sensor element by the actuator.

Abstract: An electronic selector lever module for generating gear shifting signals for an automatic transmission of a vehicle. The swivel motion of the gear selector lever, within a main shifting path, is transformed into rotational motion for an angle sensor. The sensor is positioned on a printed circuit board and is actuated by a rotor. To guide the rotor relative to the angle sensor, the rotor either surrounds a rounded part of the printed circuit board or surrounds a rotor guidance which is mounted on the printed circuit board. The mechanical linking point is a short sleeve at a slider, which both belong to the rotor, needed for the shifting path motion, and which also drive the tilting lever for the transverse motion. The slider can be moved, relative to the rotor, along rails, either radially and directly at the rotor, or tangentially to the pivot point of the rotor.
