Abstract: A thermoelectric generator includes a voltage source including a thermoelectric element, a starting circuit connected to the voltage source, a DC to DC converter circuit connected to the voltage source, an output connected to the starting circuit and connected to the DC to DC converter circuit, and a controller having an input connected to the voltage source, and outputs connected to the starting circuit and to the DC to DC converter circuit. The controller deactivates the starting circuit and activates the DC to DC converter circuit when a voltage at the output or when a voltage provided by the voltage source rises above a predefined upper voltage threshold. Additionally, the controller reactivates the starting circuit and deactivates the DC to DC converter circuit when a voltage at the output or when a voltage provided by the voltage source drops below a predefined lower voltage threshold.

Abstract: A process for producing a metal alloy balance wheel by molding includes a) making a mold in the negative shape of the balance wheel; b) obtaining a metal alloy that has a thermal expansion coefficient of less than 25 ppm/° C. and is able to be in an at least partly amorphous state when it is heated to a temperature between its glass transition temperature and its crystallization temperature; c) putting the metal alloy into the mold, the metal alloy being heated to a temperature between its glass transition temperature and its crystallization temperature so as to be hot-molded and to form a balance wheel; d) cooling the metal alloy to obtain a balance wheel made of the metal alloy; and e) releasing the balance wheel obtained in step d) from its mold. The process also includes a step for over-molding flexible centering components in the hub.
