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.

Abstract: Regulating members for a mechanical timepiece, specifically a system based on magnetic interaction between a resonator, in a form of a tuning fork for example, and an escape wheel, as a magnetic escapement. In the system plural areas of magnetic interaction between the resonator and the escape wheel are arranged such that torques produced at the escape wheel by the interactions compensate each other if the escape wheel is not synchronized at the frequency of the resonator. This results in negligible torque in the escape wheel when the escape wheel rotates slowly in a direction of an arrow or opposite direction. This allows the timepiece to start with a low mainspring torque and without any start procedure or device and provides better resistance of the timepiece against a loss of synchronization in event of a shock.

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 timepiece (2) includes an actuator, which applies braking pulses to the balance, which has an electromechanical device (6) and an electric control circuit (8). The device (6) includes a flexible member (16), formed by an elastic blade (20) and a mechanical element (22) defining a braking pad, and an electromagnetic system (10) formed by a coil carried by the flexible member and by a permanent magnet rigidly connected to a support (18) of the electromechanical device. When an electric pulse is provided to the coil, an electromagnetic force of repulsion is engendered between the coil and the permanent magnet so the mechanical element moves to a position of contact with the balance. To stabilise the rest position of the flexible member, a magnetic element (26) is rigidly connected to the coil to exert a magnetic return force complementary to the force of the elastic blade is provided.

CPC classification number: G04B11/005 , G04B13/02
Abstract: A timepiece mechanism including a magnetic gear formed of a first wheel and a second wheel, the first wheel being provided with first alternating magnetic poles forming a magnetic toothing and the second wheel being provided with a toothing made of ferromagnetic material which has a magnetic coupling with the magnetic toothing, such that, when one of the first or second wheels is driven in rotation, this wheel rolls, via the magnetic coupling, over a geometric circle centred on the other wheel and linked to this other wheel. The magnetic gear further includes a ferromagnetic element arranged relative to the first wheel so as to offset at least most of a magnetic disturbance torque to which the first wheel is subjected, resulting from the magnetic coupling, this magnetic disturbance torque having a periodic variation in intensity according to the angular position of the first wheel.
