Abstract: A balance for timepieces includes a rim, a hub, and at least one arm connecting the hub to the rim. At least one portion of the balance is made of an at least partially amorphous metal alloy. The at least partially amorphous metal alloy is based on an element chosen from the group consisting of platinum, zirconium and titanium, and has a coefficient of thermal expansion comprised between 7 ppm/° C. and 12 ppm/° C. The balance can be manufactured by moulding. A resonator can include such a balance and a monocrystalline quartz balance spring.

Abstract: A method for calibrating an electronic temperature sensor connected to a mobile device. The device includes a microprocessor and memory linked to the microprocessor, to store an application coupled to a data entry interface. The temperature sensor is initially placed in a plurality of predetermined environments, where it provides an initial raw temperature value measured in each environment, and, for each of these environments, a predetermined initial temperature value corresponding to the actual temperature of this environment is entered beforehand directly into the application via the interface. The method includes in computing a calibration curve according to each predetermined initial temperature value entered from the application and according to each corresponding initial raw temperature value provided by the temperature sensor, storing in the device or in the sensor, calibration parameters determined from the calibration curve, and correcting by the calibration parameters each raw temperature value measured by the sensor.

Abstract: The present invention relates to a safety valve including: a tube intended to be fixed to a watch case, a hollow head mounted for rotation about the tube, a first element fixedly mounted with respect to the head and a second element integral with the head, wherein the first element and the second element each include one or more passages allowing gas to flow, the rotational motion of the head allowing the passages of the first element and of the second element to be placed in communication for gas to escape from the interior to the exterior of the case in case of overpressure inside the case or, conversely, allowing the passages of the first element and of the second element to be moved out of alignment to prevent gas escaping.

Abstract: The active lighting device of a bicycle includes a first optical system with a first light source for long-distance illumination, controlled by a control unit, and a second optical system with a second light source for short-distance illumination, controlled by the control unit. It includes a light sensor for determining the light intensity of a location in which the bicycle is situated and allows the control unit to adapt the light intensity of the light sources, if they are activated and if the ambient light intensity is below a determined light threshold. Moreover, a speed sensor is provided for determining the speed of the bicycle in use on a path, so that the control unit controls the activation of the first light source from at least one determined speed threshold. An orientation detector is provided for orienting the light sources depending on a curve travelled by the bicycle in use.

Abstract: A portable object includes a near-field communication device. The communication device includes an electronic chip provided with two terminals connected to an electrical circuit including an antenna and a filter. The communication device is provided to receive and transmit at a defined frequency corresponding to the resonance frequency of the electrical circuit. The portable object includes a control element which is able to be displaced between two predefined positions, i.e. an active position in which the communication device is activated and a passive position in which the communication device is deactivated. The electrical circuit includes, furthermore, a bypass branch provided with a mechanical switch which is able to switch between an open state and a closed state in response to a displacement of the control element from one to the other of its predefined positions causing a modification in the resonance frequency of the electrical circuit.

Abstract: A process for producing a metal alloy balance wheel by molding, the process including the following steps: a) making a mold in the negative shape of the balance wheel, b) getting hold of 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, e) releasing the balance wheel obtained in step d) from its mold.

Abstract: The smart battery includes an electronic circuit for managing the supply voltage connected to a battery. The electronic circuit includes a battery end-of-life detector, a management unit, an oscillator stage, a DC-DC converter powered on when the supply voltage of the battery is close or equal to a battery end-of-life threshold, and a data or command communication interface. The data or command communication interface is a 1-wire interface which is connected to a positive supply voltage terminal of the smart battery for transmitting a modulated data or command signal through one of the supply voltage terminals. The modulated signal transmitted by the interface may include battery end-of-life information.

Abstract: A timepiece indicates the sunrise and sunset taking into account seasonal variations. The timepiece includes a sphere representing the Earth, a shell arranged concentrically to the sphere and arranged to delimit a part of the globe where it is night time from another part where it is daytime by indicating the position of the Earth's terminator. The shell can pivot around the globe along two perpendicular axes. The shell is driven by the movement in order to revolve at the rate of one revolution every 24 hours around the polar axis. A differential mechanism is controlled by a year cam that has a profile representing the inclination of the sun in relation to the equatorial plane. The differential mechanism controls the inclination of the shell around the axis by a drive shaft concentric to the polar axis.
