A system is provided with a magnetic field sensor being positioned in a magnetic field of a magnet that is coupled to a rotatable driving shaft. The magnetic field sensor is configured to sense a rotation of the magnetic field in response to a rotation of the rotatable driving shaft, and generate an angle sensor signal based on an orientation angle of the magnetic field. The angle sensor signal includes angular values that represent an absolute orientation angle of the rotatable driving shaft. The system includes a memory storing a mapping of values of a patterned signal to the angular values, electronic circuitry configured to generate, based on the angular values and the stored mapping, the patterned signal, and a signal generator circuit configured to generate a signal representing the absolute orientation angle of the rotatable driving shaft based on the angle sensor signal.

A system for checking the attitude angles of wheels is provided, in a manner that is known per se, with a vertical measuring or column 1 on which some transmitters and receivers of electromagnetic signals are installed—for example coherent light illuminators (typically lasers) and associated reflected light sensor—which overall define a group of distance sensors.

According to the disclosure, the proposed system is produced using distance sensors appropriately fitted on a single vertical measuring structure which is positioned, on a side of a movement path, where the vehicle equipped with wheels moves, that has a substantially transverse direction with respect to the acquisition direction of the distance sensors.

A wheel clamp (2) for fastening to a wheel (1), in particular to a wheel (1) of a motor vehicle, comprises at least two arms (22, 23, 24) which extend outward from a center (28) of the wheel clamp (2) in a radial direction. Each of the arms (22, 23, 24) has at least one movable element (32, 33, 34) which is movable in the radial direction. The wheel clamp (2) comprises a locking member (82) which is designed such that the movable elements (32, 33, 34), by operation of the locking member (82), can be fixed such that the movable elements (32, 33, 34) are no longer movable in the radial direction. The wheel clamp (2) also comprises an unlocking member (84) which is designed such that a fixation of the movable elements (32, 33, 34) can be released by operation of the unlocking member (84).
