A hybrid position sensor for determining a position of a hybrid target includes a conductive target and a magnet configuration which are rigidly connected and at least partially overlapping. The position sensor has a first transducer configured for generating a first signal induced by the conductive target and indicative for the position of the hybrid target; a second transducer, at least partially overlapping with the first transducer, and configured for generating a second signal induced by the magnet configuration and indicative for the position of the hybrid target; a processing device configured for receiving the first signal to determine a first position of the hybrid target and for receiving the second signal to determine a second position of the hybrid target and for determining reliability of the position sensor based on the determined first and second position.

A multi-pole annular encoder having 2N poles distributed irregularly is positioned facing a sensor that detects transitions between the poles. Times corresponding to the detected transitions are stored and the times that have elapsed between each transition and the previous transition of order 2N, which constitute durations for a complete revolution of a rotating member, are calculated. When the durations thus calculated are stable, a time that has elapsed between a tested transition and the previous transition is calculated, and a characteristic angle of the tested transition is deduced therefrom, this being proportional to a ratio between a time that has elapsed since the previous transition and a stabilized duration for a complete revolution. An index transition is identified and is used to ascertain absolute position of the encoder with respect to the sensor.

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.

A pole wheel is provided. The pole wheel can be mounted on a brake disk of a vehicle wheel brake. The pole wheel has apertures which are uniformly distributed over its circumference and which are spaced apart from one another by radial webs. The pole wheel has an axially protruding bulge radially above its apertures and radial webs.

A linear rotary encoder includes a pair of rotational surfaces. A contact belt has a first end coupled to a first rotational surface in the pair and a second end coupled to a second rotational surface in the pair. The contact belt is driven to rotate around the pair of rotational surfaces by a driving force applied to media to move the media from the first end toward the second end. An encoding scale is coupled to an inner surface of the contact belt. A reader is positioned to read the encoding scale as the contact belt rotates around the pair of rotational surfaces. The reader generates an output signal indicating a position of the media based on reading of the encoding scale.

An inductive angle measuring device includes a scanning element and a scale element having scale tracks. First and third scale tracks have an equal first number of scale structures, and a second scale track has a different number of scale structures. The scale tracks are arranged circumferentially and concentrically about an axis, such that the first scale track is located radially inwardly, the second scale track is located radially between the first scale track and the third scale track, and the third scale track is located radially outwardly. The scanning element includes receiver conductors by which the signals having angle-related signal periods can be generated. The first signal period is equal to the third signal period. An overall signal can be generated from the first signal and the third signal and can be combined with the second signal for determining absolute angle position information.

A position encoder arrangement is configured to detect the position of a movable source based on a source field, which is a magnetic field or an electric field, emitted by the source. The position encoder arrangement includes a number of sensor elements that are evenly distributed and each is configured to provide a sensor value based on the source field at the sensor element's location. The arrangement further includes an evaluation unit that is configured to determine a fine position value for the position of the movable source, and to determine from the sensor values a trustworthiness of the fine position value and/or an error flag indicating whether a failure status of the position encoder arrangement is present.
