    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 regulating members for a mechanical timepiece, specifically a system based on the magnetic interaction between a resonator, in the form of a tuning fork for example, and an escape wheel, called a “magnetic escapement”. The system is characterized in that there are several areas of magnetic interaction between the resonator and the escape wheel which are arranged such that the torques produced at the escape wheel by these 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 latter rotates slowly in the direction of the arrow or the 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 the event of a shock.

    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: 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 transducer device of a wearable object or as a wearable object as such, includes means for generating a first action in a first operating mode related to a specific function of the wearable object under the control of a processor or microcontroller processing unit of an electronic circuit being powered by a DC voltage source. The means for generating is configured to generate a second communication action in a second operating mode different from the first operating mode so as to obtain a dual-mode transducer device. The second operating mode allows information or data communication signals to be communicated mainly to the outside of the transducer device so that it can be detected by a monitoring unit of a monitoring system, is able to establish communication, and can receive data or parameter signals from another transducer device. The communication signals are ultrasonic signals transmitted into a water body.

    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.
