摘要： A power management method for a solar watch or a solar automatic watch. The power management method including at least one providing a primary power supply from at least one energy supplier. The primary power supply is converted to a secondary power supply when the primary power supply reaches at least one primary threshold and/or at least one secondary threshold. A motor is supplied with the secondary power supply such as to wind a mainspring via the motor.

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 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： 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 control device (2) for controlling power supply to a continuous-rotation motor, of the horological, DC type, is arranged to generate electrical pulses with a lower supply voltage to drive the rotor. The number of pulses per time interval is a function of the load applied to the motor. A voltage divider is arranged to supply the lower supply voltage with a plurality of different values and thus the electrical pulses with a variable voltage. A logic circuit counts the numbers of electrical pulses in successive time periods; to periodically select a voltage value, from among a plurality of different values, as a function of a counted number of electrical pulses or of a succession of counted numbers of electrical pulses; and to control the voltage divider so that the latter supplies the lower supply voltage with the selected voltage value after the selection of this voltage value.

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： 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： 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.
