Abstract: A portable object includes a case forming a housing in which is arranged a device requiring air to operate. The case includes at least a first opening. The portable object further includes a closure device provided with a valve system arranged to have a first stable, open position in which the orifice is open and allows air to pass through, and a second stable, closed position, in which the orifice is closed so that the portable object is impermeable to gases and to liquids. Switching from the open position to the closed position is automatic in case of immersion.

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.
