摘要:
A method of controlling a machine with redundant parallel actuation includes a frame and a mobile element driven by a plurality of mechanical transmissions parallel to one another and each being activated by an actuator (2) including a body fixed to the frame, an actuating member and a position sensor, in which an error signal is produced by comparing the position of each actuator with a setpoint signal, characterized in that the error signals are converted into a mobile element position error signal by applying data representative of the kinematics of the mechanical transmissions, the mobile element error signal is processed by a processing module which produces an effort signal to be applied to the mobile element, the effort signal is converted into signals controlling the actuators by applying data representative of the kinematics of the mechanical transmissions.

An electronic temperature sensor for measuring the junction temperature of an electronic power switch (4) of a static converter (8) includes an injection source of a calibrated measurement current (20) and a differential voltage measurement amplifier (76; 276). The electronic temperature sensor includes a first series connection (26) element and a second series connection (28) connected respectively to the inlet terminals (78, 80) of the differential voltage amplifier (76; 276). The first and second series connection elements (26, 28; 224, 226) are configured to protect the amplifier against a high voltage, have essentially identical electrical characteristics and are included in the set formed by resistances and high-voltage (HV) rapid diodes.

This method comprises bringing drops to be separated into contact with an interface (40) suitable for allowing an osmotic equilibrium between the content of each drop to be separated. The method comprises an osmotic flow between the drops (20A) of the first group of drops through the interface (40) in order to modify the density of each drop (20A) of the first group of drops and the separation of the drops (20A, 20B) according to the density thereof or a combination of the density and the volume in order to isolate the drops (20A) of the first group of drops from the drops (20B) of a second group of drops.

The invention relates to a static converter connected between an electrical voltage source and an electrical load, said converter including a main static conversion arm comprising an output electronic switching cell and a backup conversion arm having identical structures. The static converter includes a pair of fuses connected on either side of the main arm, and a switching circuit comprising a connection element connecting the backup arm to the connection points between the fuses and the input terminals of the main arm, such that, when a fault occurs on one of the switching cells forming the main arm, a stable conductive link is established between the two fuses, the main arm is isolated by the two fuses, and the backup arm is spontaneously connected to the output of the main arm via the conductive line and replaces the main arm.
摘要:
A method for preparing a composition of metal nanocrystals from at least one organometallic precursor in a solvent medium in the presence of a PEG ligand, including a carbon chain, at least one end of which is functionalized by a coordination grouping including at least one hetero atom, and having at least one [OCH2CH2]n grouping, n being an integer higher than 1, so as to be soluble both in the solvent medium and in water. The water-compatible and organic-compatible composition of metal nanocrystals thus obtained is also described.
