Abstract: A sensor readout includes a selector circuit, a predictor circuit, and a select controller. The selector circuit receives a plurality of actual sensor inputs. Each actual sensor input is provided to the selector circuit along a corresponding channel. The selector circuit also passes a selected sensor input. The predictor circuit receives the selected sensor input into a signal history and generates predicted sensor inputs. The select controller receives the predicted sensor inputs, determines which of the predicted sensor inputs is most changed from the actual sensor inputs as the most changed input, and directs the selector circuit to pass a next signal on a the channel having the most changed input.

Abstract: In a method of determining residual error compensation parameters for a magnetoresistive angle sensor providing a first measurement signal depending on a rotational angle the step of generating a plurality of value pairs for a plurality of rotational angle values is provided, wherein each value pair has a rotational angle value and an associated measurement signal value. The method further includes ascertaining a sinusoidal fit function the course of which is adapted to the plurality of value pairs. Finally, residual error compensation parameters can be generated from a difference between the ascertained sinusoidal fit function and the associated measurement signal values of the measurement signal for the plurality of rotational angle values.

Abstract: A method for determining the angular position of a rotating object and rotary encoder is disclosed. In one embodiment, the method includes a method for determining the angular position of an object rotating about a rotation axis in a rotation direction and having a coding pattern, using a sensor that senses the coding pattern, including ascertaining the coarse angular position of the rotating object with respect to the sensor whilst taking account of the coding pattern at a first instant. The exact angular position of the rotating object is ascertained with respect to the sensor whilst taking account of the coarsely ascertained angular position and also whilst taking account of at least one section of the coding pattern which extends counter to the rotation direction proceeding from that location of the coding pattern which is assigned to the coarse angular position. An output signal is provided containing items of information about the exact angular position of the rotating object with respect to the sensor.
