A first sensor signal and a second sensor signal are provided by a sensor unit to an evaluation unit. The first sensor signal is dependent on the angular position and is associated with a first detection position, and the second sensor signal is associated with a second detection position lying about the rotational axis perpendicular to the first detection position. An angular position of a rotational component is determined by the evaluation unit based on output from an atan2-function that takes the first and second sensor signals as input. A harmonic error is determined by the evaluation unit based on a periodic error signal that is superimposed on each of the sensor signals. An angular error of the angular position is determined by the evaluation unit based on the harmonic error. The angular position is updated by the evaluation unit based on the angular error.

An easily inspected shaft assembly is provided and includes a shaft, a sleeve receptive of a portion of the shaft and an optically activatable layer including first and second sections disposed on respective exterior surfaces of the shaft and the sleeve, respectively, such that the first and second sections move relative to one another as the shaft and the sleeve move relative to one another.

A torque transmitting assembly including a first drum having a plurality of teeth formed at an end thereof and a sensor component annularly extending on an inner surface of the first drum. A gear assembly axially aligns with the first drum and has a plurality of teeth intermeshing with the plurality of teeth of the drum. The gear assembly includes an annular gear and a plate axially aligning with the gear.

A torque limiter device includes an input shaft having a first contact surface and an output shaft having a second contact surface. The input and output shafts are operable in an engaged position wherein the contact surfaces are brought into mechanical engagement, and a disengaged position wherein the contact surfaces are separated. A biasing mechanism provides a bias force that mechanically biases the input and output shafts in one of the positions and sets a threshold torque. An electromagnet is arranged to selectively provide an electromagnetic force that opposes the bias force when an activation current is supplied. A rotation sensor arrangement measures a respective rotation of the input shaft and of the output shaft. A controller determines a difference in rotations of the shafts and selectively supply the activation current to the electromagnet so as to disengage the input and output shafts when the rotation difference exceeds a threshold.

A first sensor signal and a second sensor signal are provided by a sensor unit to an evaluation unit. The first sensor signal is dependent on the angular position, and the second sensor signal is phase-shifted by 90° with respect to the first sensor signal. A noise value that is superimposed on each sensor signal due to noise in the corresponding sensor signal is determined by the evaluation unit. Each sensor signal is corrected by the evaluation unit based on the noise value determined for the corresponding sensor signal. Highest amplitudes for each of the first and second sensor signals are determined by the evaluation unit as a maximum value of amplitudes of the respective sensor signals detected over multiple revolutions of the rotational element. An angular portion of a rotational component is determined by the evaluation unit based on output from an atan2-function that takes the first and second sensor signals and the highest amplitudes as input.
