Computer processor controlled energy harvester system. The system uses a plurality of oscillating weight type energy collectors, each configured to store the energy from changes in the system's ambient motion as stored mechanical energy, often in a compressed spring. 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, usually one per energy collector, control when each energy collector stores and releases energy. The processor can use accelerometer sensors, battery charge sensors, and suitable software and firmware to optimize system function. The system can use the energy for various useful purposes, including sensor monitoring, data acquisition, wireless communications, and the like, and can also receive supplemental power from other sources.

Timepiece wheel set with a unidirectional wheel rotating in only one direction in cooperation with a ratchet wheel, which is movable inside a ratchet wheel chamber, comprising a click that rotates integrally with this wheel, which forms a one-piece component comprising at least one spring-arm, at the end of which, on a first side, a beak cooperates directly with the toothing of a ratchet wheel in an operating position in which this spring-arm is free, and on a second side, a first hook can cooperate with a second hook of complementary shape, comprised in this one-piece click, in a rest position in which this spring-arm is in an extended position, the elasticity thereof allowing this first hook to be hooked or unhooked with respect to this second hook by the action of an operator, by maximum elongation of this spring-arm and/or by the tilting of this end.
