Abstract: A position sensor and method for determining an axial and/or an angular position of a setting stem of a timepiece. A magnet is provided on the setting stem, and at least one magnetic field sensor is configured to detect changes in magnetic field strength along at least a first axis and a second axis as the rotatable element rotates; the second axis is not parallel to the first axis. The changing magnetic field sensed by the magnetic sensor is converted into a characteristic signature path which may then be mapped onto a circular signature path in two dimensions to derive the angular position of the setting stem.

Abstract: A mechanism (1) including a magnetic gear (2) including a first wheel (6B) and a second wheel (6C) provided with a first magnetic toothing (10) and a second magnetic toothing (12) respectively. The first and second magnetic toothings are respectively formed by first and second teeth made of a soft ferromagnetic material; and the magnetic gear (2) further includes a third wheel (6A) arranged between the first and second wheels (6B, 6C) and provided with a third magnetic toothing (8) formed by permanent magnetic poles, in particular by bipolar magnets. In general, the first wheel is a drive wheel, whereas the second wheel is driven into order to carry out a function or transmit a torque. The third intermediate wheel is preferably mounted such that it can rotate freely.

Abstract: The present invention concerns a method of controlling a rotational speed of a rotor (3) of a direct current electric motor (1) comprising an inductor circuit (A, B) for rotating the rotor, which is configured to rotate continuously and is equipped with permanent magnets. The method comprises: measuring the rotational speed of the rotor; determining a time drift in the rotor rotation compared to a reference signal; defining N speed thresholds with at least one being a variable speed threshold depending on the determined time drift, the N speed thresholds defining N+1 rotational speed ranges for the rotor; determining in which one of the N+1 rotational speed ranges the determined rotational speed of the rotor is; and finally selecting an action relative to the control of the inductor circuit, based on the determined rotational speed range, for controlling the rotational speed of the rotor.
