Abstract: An electric power-generating device (1) comprising a movable portion forming a magnetic circuit fitted with a core (5) and branches (11, 12, 13, 14) coupled magnetically to the said core, a fixed portion provided with a permanent magnet (31, 32, 33, 34), a mechanism for rotating the movable portion about an axis of rotation (20) supporting the said core, and an electric coil (21) wound around the said core in order to gather the electric power obtained when the said movable portion rotates, the said generating device comprising priming and driving means (51, 52) coupled to control means (71, 72) in order to establish a priming of the said mechanism and interacting with the said movable portion in order to drive it by releasing a priming power at the end of travel of the said control means. A remote control provided with the generating device.

Abstract: A rotary machine including two coaxial parts, the first part including an intermediate part, an energizing coil, and fingers distributed around the circumference of the intermediate part with a constant finger pitch and directed alternately in opposite directions. The fingers are positioned so as to interlace over part of the coil. The second part includes a permanent magnet and two lateral parts mounted substantially coaxially, the lateral parts being secured to the permanent magnetic part so as to have opposite polarities, the lateral parts including protrusions distributed around the circumference of the lateral parts and arranged in alternation on one and the other of the lateral parts with a protrusion pitch substantially equal to the finger pitch. A control device can be equipped with such a rotary machine.

Abstract: A bistable electromagnetic actuator comprising a magnetic circuit comprising a magnetic yoke in which a shunt extends perpendicularly to a longitudinal axis of said yoke and comprising a permanent magnet positioned between a first surface of the yoke and the shunt. A plunger core is fitted with axial sliding between a latched position and an unlatched position. A coil extending between the shunt and a second surface of the yoke is designed to generate a first magnetic control flux to move the plunger core from an unlatched position to a latched position. A second magnetic control flux enables the plunger core to move from the latched position to the unlatched position by the action of a return spring.

Abstract: The present invention relates to a stand-alone device for generating electrical energy comprising:—an excitation coil (2) furnished with a central opening, —a magnetic circuit passing through the central opening of the coil and formed of a fixed part (3) and a movable part (5) that can move with respect to the fixed part (3) so as to vary the magnetic flux through the excitation coil (2), characterized in that, —the magnetic circuit passes through the central opening of the excitation coil (2) several times, forming at least one loop. The invention also relates to a remote control device comprising a transmitter coupled to a remote receiver and a stand-alone device (1) for generating electrical energy so as to generate an electric current intended to power its transmitter.
