Abstract (en)

[origin: US2017017205A1] A microsystem for setting the rate of a timepiece oscillator, including a wheel/inertia block including an off-centre unbalance and a toothing and arranged to pivot with respect to a base plate of the microsystem, which includes an actuator driving a first active click arranged to drive the toothing, and includes a device for stopping the toothing in position, wherein the actuator is a thermomechanical actuator arranged to convert a flow of light energy into a displacement of a distal end of the thermomechanical actuator, which carries a first active click or directly controls a movement of a first active click, and the microsystem is capable of incorporation in a watch including a crystal transparent to predetermined wavelengths ranges and allowing the passage of a light ray to regulate the microsystem.
