Abstract: A mechanism including a rotary element and a magnetic device for guiding this rotary element in rotation arranged so as to exert a radial magnetic biasing force on the rotary element when a central axis of this rotary element undergoes a radial movement relative to a given axis of rotation. The magnetic device includes a pair of annular magnets the first annular magnet of which is carried by the rotary element and the second annular magnet is carried by a structure of the mechanism. The second annular magnet is parallel and axially superimposed with the first annular magnet when the central axis of the rotary element is coincident with the axis of rotation, the first and second annular magnets being arranged in magnetic attraction so as to impart on one another an axial magnetic force and a radial magnetic force.

Abstract: A mechanism including a magnetic gear including a first wheel, a second wheel and a third wheel. The first wheel is provided with permanent magnetic poles which are arranged so as to form the magnetised teeth of a first magnetic toothing. The second wheel and the third wheel are provided with teeth made of a soft ferromagnetic material respectively defining a second magnetic toothing and a third magnetic toothing, each with a number of teeth that is greater than that of the first magnetic toothing and having a magnetic coupling with this first magnetic toothing. The second magnetic toothing is directly coupled with the first magnetic toothing and with the third magnetic toothing thanks to the magnetic fluxes provided by the magnetised teeth of the first toothing and the teeth of the second magnetic toothing are magnetically separated from one another.

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: A wearable object (42) including an electronic unit and a power supply unit formed by an electromechanical converter (6A) which includes a rotor (44) carrying first magnets (10A), a mechanical resonator (12A) provided with an inertia mass (46) capable of oscillating at a relatively high resonant frequency and carrying second magnets (20), and coils arranged so that, when the mechanical resonator is oscillating, an induced voltage is generated in these coils. The electromechanical converter is arranged so that the first magnets and the second magnets can, during a rotational drive of the rotor, interact magnetically so as to apply to the inertia mass, momentarily or temporarily, a magnetic force torque allowing to excite the mechanical resonator, in order to generate at least one oscillation of this mechanical resonator at its resonant frequency in order to generate a relatively high induced voltage allowing to recharge an accumulator.
