The invention relates to an oscillating weight (1) with variable geometry for a timepiece mechanism, comprising: a first and a second part (10; 20), an axis of rotation (40) shared by the first and the second part (10; 20), at least one part (10; 20) being arranged in order to oscillate about said axis of rotation, a differential mechanism (30) connected to the first and to the second part (10; 20) so as to vary the position of one part relative to the other through a rotational movement of at least one of the parts about the axis of rotation (40).

Owing to the presence of the differential mechanism (30), the user of the watch can vary the geometry of the oscillating weight (1) directly and therefore the position of its centre of gravity, and thus adapt it to their lifestyle (for example, sport mode, normal mode).

A transmission horological mechanism is disclosed, which includes: a transmission wheel including a driving plate, intended to pivot about a first axis of rotation in response to the movements of a driving wheel; and a link organ having a flexible portion and bearing a unidirectional transmission organ arranged to cooperate with an output wheel intended to drive a driven wheel when the driving wheel is displaced in a first direction of displacement. The link organ includes: a base secured to the driving plate and arranged to exhibit a rotational movement about the first fixed axis of rotation, in response to the movements of the driving wheel; and a first arm extending from the base and bearing the unidirectional transmission organ at its distal end, the flexible portion being arranged on the first arm.

The present invention relates to a direct escapement mechanism (1) having an escape wheel (2) provided with a series of peripheral teeth (3), and an anchor (4), having an entry-pallet (10) and an exit-pallet (11) each having a locking plane (10p, 11p) and also having a fork (43). It also comprises a pin (6) which can be rigidly connected to a regulating organ (5) to cooperate at each alternation of said regulating organ (5) with the fork (43) of the anchor in order to unlock at least partially said anchor from the escape wheel (2) as well as at least one impulse pallet (9) which can be rigidly connected to said regulating organ (5) to cooperate with a tooth (3) of the escape wheel to transmit a direct impulse to said regulating organ (5). Typically, at least the teeth (3) of the escape wheel or one of the entry-pallets or exit-pallets (11) comprises in the extension of said locking plane (10p, 11p) a inclined plane (3i, 10i, 11i) arranged to provide an indirect impulse to said regulating organ (5) during a movement of said pallet in the path C of the escape wheel (2) by rotating the anchor (4) on its axis (X3). The invention also relates to a timepiece incorporating such an escapement mechanism.

A direct impulse free escapement mechanism for a timepiece includes: an escapement wheel with peripheral teeth; a locking device including a locking pallet engaging an escapement wheel tooth in a locking position of the locking device; and a control pallet actuated by a pivoting regulating organ to engage a complementary unlocking organ of the locking device to release the locking device from the escapement wheel in an unlocking position at each alternation of the regulating organ. Also included are impulse pallets attachable to the regulating organ, cooperating on an impulse plane with a tooth of the escapement wheel to transmit a direct impulse to the regulating organ. The locking device is drawn by the escapement wheel in each locking position. The teeth of the escapement wheel and the impulse pallets are configured so the impulses occur outside the plane of the escapement wheel. A corresponding timepiece is also disclosed.

Computer-processor controlled energy harvester system optimized for use on mobile platforms. The system uses a plurality of oscillating weight type energy collectors, each configured to store the energy from changes in the system's ambient acceleration as stored mechanical energy. The energy collectors are configured to move between a first position where the energy collector stores energy, to a second position where the energy collectors release stored energy to a geared electrical generator shaft, thus producing electrical energy, often stored in a battery. A plurality of processor controlled electronic actuators control when each energy collector stores and releases energy. The processor can use battery charge sensors, and suitable software and firmware to optimize system function. To facilitate use on mobile platforms, the processor also uses input from a 3-axis accelerometer to dynamically reconfigure the energy collectors according to the present major directions of ambient acceleration.
