摘要： A motor drive unit for driving a direct current electric motor including a moving part equipped with permanent magnets. The motor drive unit, which is powered by a voltage supply source, includes a switch circuit, an inductor circuit and a capacitor circuit including a set of capacitors. By selectively opening and closing the switches of the switch circuit, a series of consecutive low energy pulses can be generated such that the power consumption of the motor drive circuit is minimized.

摘要： A method of detecting and calculating height of a jump performed by an individual including detection of a reception subsequent to the jump is described. The detection includes a sub-step of detecting a pressure spike of amplitude greater than a first threshold amplitude, within pressure measurements provided by a pressure sensor embedded aboard a watch worn on the wrist of the individual. Also described is calculation of a height of the jump by differencing a starting altitude corresponding to a last stable pressure measured before the pressure spike and a finishing altitude corresponding to a first stable pressure measured after the pressure spike via the pressure sensor, a stable pressure being defined as a pressure whose variations do not exceed 0.1 hectopascals for at least 2 seconds.

摘要： The invention relates to a method for detecting and calculating the duration of a jump effected by an individual, comprising the following steps: Detection of a moment associated with a landing following the jump, this step comprising a sub-step of detecting an acceleration peak of an amplitude greater than a first threshold amplitude, within the acceleration measurements provided by a three-axis accelerometer, on board a watch worn on the wrist of the individual. Detection of a jump phase, by detection, in a temporal window finishing at the moment of landing, of a succession of acceleration measurements between 0 g and 0.5 g during a duration greater than a first threshold duration.

摘要： 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.

摘要： 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.

摘要： The present invention concerns a method of controlling a rotational speed of a rotor (3) of a direct current electric motor (1) comprising an inductor circuit (A, B) for rotating the rotor, which is configured to rotate continuously and is equipped with permanent magnets. The method comprises: measuring the rotational speed of the rotor; determining a time drift in the rotor rotation compared to a reference signal; defining N speed thresholds with at least one being a variable speed threshold depending on the determined time drift, the N speed thresholds defining N+1 rotational speed ranges for the rotor; determining in which one of the N+1 rotational speed ranges the determined rotational speed of the rotor is; and finally selecting an action relative to the control of the inductor circuit, based on the determined rotational speed range, for controlling the rotational speed of the rotor.

摘要： A DC motor including a continuous rotation rotor; a first inductor characterized by first parameters; a second inductor characterized by second parameters; a voltage supply unit; a measurement unit for detecting time instants when a first induced voltage in the first inductor equals a second induced voltage in the second inductor; and a control unit for controlling the application of drive voltage pulses to the inductors. The rotor faces first the second inductor before facing the first inductor when being rotated. At least one of the second parameters is selected different from a corresponding parameter of the first parameters such that a maximum induced voltage in the first inductor is greater than a maximum induced voltage in the second inductor. The control unit is arranged to trigger each of the drive voltage pulses after a detection of an equal induced voltage in the first and second inductors.

摘要： The electronic device is provided with an automatic leak detection means, notably for a gas leak, in the case of the device. The automatic leak detection means includes a pressure sensor, a temperature sensor and a calculation unit connected to the pressure sensor and to the temperature sensor. The calculation unit, which is a microcontroller, the pressure sensor and the temperature sensor are arranged inside the case. In operation, the microcontroller checks, based on measurements performed by the pressure sensor and the temperature sensor over time, whether the variation in pressure in the case is within a defined margin proportional to the variation in temperature to determine whether or not the case has a sufficient degree of sealing.

摘要： A portable object includes a case forming a housing inside which is arranged a device that requires air to operate, and a closure device including at least one permeable element. The closure device is arranged to provide impermeability to liquids while allowing the atmosphere inside the housing to communicate with the external atmosphere. The case comprises a recess in which a through opening is made, the recess being closed by the closure device. The closure device includes a permeable module mounted to move such that, in a gaseous environment, the permeable module is in a rest position allowing gases to penetrate the case opening through the permeable module, and in a liquid environment, the permeable module is in an operating position in which gases and liquids are blocked. The permeable module comprises a tubular support at the end of which is fixed a membrane.
