摘要： A method for identifying the existence of a failure of a relay device in an electrical power supply system of a device to be supplied with power, the power supply system comprising at least one power generator configured to generate a power supply signal and a load comprising at least one relay device; the power generator comprising a frequency variator; each relay device comprising a quadripole and at least one antenna linked to the quadripole. The identification method comprises the following steps: a) selecting a characteristic frequency, b) determining the impedance of the load, then when the supply signal has the selected characteristic frequency, c) repeating steps a) and b) for several distinct characteristic frequencies, d) identifying the existence of a failure from several impedances determined for different characteristic frequencies.

摘要： In a gyroscopic system, a vibrating gyroscope is controlled in gyrometer mode in a control loop. The control loop corresponds to at least one current control for an operating parameter. In the control loop, a modified control to be applied to the gyrometer for said operating parameter is obtained (11) by introducing a sinusoidal interference into the current control. Then, the modified control is applied (12) to the gyrometer as the current control. A resulting measurement value (13) is determined. A sinusoidal interference (14) is calculated as a function of said measurement value. Lastly, on the basis of the measurement value, it is decided (15) whether to repeat the previous steps on the basis of the sinusoidal interference last determined.

摘要： The invention relates to an actuating device comprising: —a first element (7), —a second element (8) able to move translationally with respect to the first element (7), and —a locking device (6) comprising a catch (18, 20) able to move between a deployed position and a retracted position, the catch (18-20) being positioned with respect to the first element (7) in such a way that when the catch (18-20) is in a deployed position, the catch (18-20) allows the second element (8) to move with respect to the first element (7) in a first range of movement (A) and prevents the second element (8) from moving with respect to the first element (7) in a second range of movement (B), and when the catch (18-20) is in the retracted position, the catch (18-20) allows the second element to move with respect to the first element (7) in the second range of movement (B). This device is particularly suited to allowing actuation of a thrust reverser system and of a system that regulates air flow through an aircraft propulsion unit.

摘要： An inertial angular sensor of MEMS type has a support of at least two masses which are mounted movably with respect to the support, at least one electrostatic actuator and at least one electrostatic detector. The masses are suspended in a frame itself connected by suspension means to the support. The actuator and the detector are designed to respectively produce and detect a vibration of the masses, and a method for balancing such a sensor provided with at least one load detector mounted between the frame and the support and with at least one electrostatic spring placed between the frame and one of the masses and slaved so as to ensure dynamic balancing of the sensor as a function of a measurement signal of the load sensor.

摘要： An aeroengine control device comprising a mount, having pivotally mounted thereon a code wheel together with a main lever and a secondary lever, both for turning the code wheel, each lever being movable between a rest position and a maximum actuation position, the secondary lever being mounted to pivot on the main lever. A connecting rod connects the secondary lever in permanent manner to the code wheel and the main lever is provided with a connection member arranged to co-operate with a portion in relief secured to the code wheel and with a portion in relief secured to the mount in such a manner that the connection member attaches to the code wheel when the main lever is moved while the secondary lever is in its rest position and attaches to the mount, thereby releasing the code wheel to turn, when the secondary lever is moved while the main lever is in its rest position, while movement of either lever is prevented when the other lever is away from its rest position.
