Abstract:
The electronic device (1) is provided with an automatic leak detection means, notably for a gas leak, in the case (2) of the device. The automatic leak detection means includes an internal pressure sensor (3), an external pressure sensor (4) and a calculation unit (5) connected to the internal pressure sensor and to the external pressure sensor. The calculation unit, which is a microcontroller, and the internal pressure sensor are arranged inside the case, whereas the external pressure sensor is arranged on an external surface of the case. The microcontroller (5) checks, based on measurements performed by the pressure sensors over time, whether the pressure variation inside the case is different from the pressure variation outside the case to determine whether or not the case has a sufficient degree of sealing.

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:
Wristwatch comprising a mechanical device for executing a first mechanical function arranged to produce a first acoustic alarm signal, and an electronic device housed in a bracelet and arranged to produce a second acoustic alarm signal and/or a mechanical vibration, wherein the electronic device is arranged to produce the second acoustic alarm signal at the moment when the mechanical device for executing the first mechanical function produces the first acoustic alarm signal.
Abstract:
The invention relates to a method for mounting at least one decorative element (3) on a support (2) comprising the steps of: a. taking a support (2) provided with at least one cavity (4); b. taking at least one decorative element (3); c. filling said cavity with a composite filler material comprising at least one metal powder and at least one organic binder and having, at the moment of filling, a viscosity comprised between 1,000 mPa·s and 1,000,000 mPa·s; d. heating the composite filler material to a higher temperature than its melting point to make it liquid; e. allowing the filler material to cool to form a substrate (6); f. making at least one housing (8) in said substrate (6); g. mounting said decorative element (3) in said housing (8). The present invention also concerns a decorative support (2) provided with at least one cavity (4) filled with said filler material forming a substrate (6) in which at least one housing (8) is formed, said housing (8) being arranged to receive said decorative element (3).
