  • Patent number: 9970787
    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.

  • Publication number: 20160187161
    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.

  • Patent number: 7726208
    Abstract: A combined steering angle and torque sensor that inductively and with eddy current damping generates two absolute angle measurement signals over an angle range of 360 degrees including a first damping rotor being disposed on an end of an input shaft of steering column divided by a torsion element; a second damping rotor being disposed on an end of an output shaft of the steering column; at least one carrier being fixed to a housing of the steering column and through which the steering column passes at a right angle, the at least one carrier being fitted with flat coils in a complete angle range; and at least one passive actuating element, without periodically repeated structures, being borne on each of said first and second damping rotors, the actuating elements being in two different locations of said angle range acting on the flat coils of the at least one carrier.

  • Patent number: 7443159
    Abstract: An inductive sensor for detecting the position of a vehicle seat or for a gate shifting unit of an automatic transmission is described. The inductive sensor unit has a plurality of sensor coils that are disposed in planar fashion on a printed circuit board A conductive actuation element is guided, spaced apart, in a path over the sensor coils and an electrical evaluation circuit detects changes in inductance of the sensor coils in accordance with the path position of the actuation element and converts the changes into electrical signals corresponding to seat position signals on gear shifting signals. The actuation element is guided along the sensor coils with conductive bottom faces that are staggered in the direction of the path.
