Abstract: The present invention relates to a device for supplying electrical power to a wired system for a drone (1). The device according to the invention includes at least one power converter (4) on the ground and one power converter (2) at the level of the drone (1), regulation at the level of the converter on the ground ensures that the output voltage of the power converter (4) on the ground increases when the output current of the power converter (4) on the ground increases. The method according to the invention is intended for all wired drones, the wire (3) of which is used to supply electrical power to the drone (1).

Abstract: A device for fastening a nut (4) on the surface of a body (2) by means of a plate (5) that holds the nut (4) captive. The plate (5) has both a centering member (14) and a lug (15) projecting from its seat (6) against the body (2), which centering member and lug are housed in corresponding orifices (16, 17) in the body (2). Means for bonding by cementing or by riveting prevent the plate (5) fitted against the body (2) from moving axially. The cementing means involve melting the lug (15) inside the orifice (17) that receives it, the lug being heating to form cementing material. The plate (5) includes a cell (19) in register with the lug (15) for guiding tooling.

Abstract: An ingestible apparatus produces and processes physiological signals representative of a physiological parameter. The apparatus measures the physiological parameter from within the body of a living entity. The apparatus includes a physiological transducer circuit to sense the physiological signals, a processor to process the physiological signals in response to the physiological transducer circuit, and a transmitter that transmits the processed signals during transmission intervals which are alternated with idle intervals. The apparatus further includes a capacitor-based circuit, including at least one capacitor, to accumulate sufficient charge during one of the idle intervals to supply power to the transmitter during one of the transmission intervals.

Abstract: A piston for an internal combustion motor has a skirt with a surface, which is at least partially polished and thereafter coated with a coating having a hardness of greater than 8 GPa and having a coefficient of friction of less than 0.20. The piston has an increased performance, a longer lifetime and a reduced friction.
