Abstract: A method for controlling recharging of a battery of a hybrid vehicle when the vehicle is stationary, the vehicle including a heat engine and at least one electric machine that can simultaneously or independently generate movement of the vehicle in electric, thermal, and hybrid operating modes, according to rolling conditions and a state of charge of a traction battery providing a power supply of the electric machine. The recharging of the battery is activated when the vehicle is stationary, at request of a driver acting on a dedicated interface.

Abstract: A method for measuring a first magnetic field and the temperature of a magneto-resistive transducer includes producing, by the magneto-resistive transducer, a measurement signal dependent on the intensity of the first magnetic field and on the temperature of the magneto-resistive transducer. The method includes establishing a measurement of the intensity of the first magnetic field on the basis of the measurement signal produced and a measurement of the temperature of the magneto-resistive transducer. The method also includes generating a second magnetic field to combine with the first magnetic field to form a resultant magnetic field. The method further includes extracting from the measurement signal, the component which is dependent solely on the second magnetic field and establishing the temperature of the magneto-resistive transducer on the basis of the component extracted.

Abstract: A bidirectional Cartesian-cylindrical converter system and method for converting the spatial distribution of polarization states include a radial polarization converter capable of receiving a linearly polarized, spatially uniform, polarization distribution beam in order to convert it into a beam having a radial or azimuthal distribution of polarization states about an axis of symmetry. An optical device compensates for the phase shift induced by the radial polarization converter and is capable of introducing a spatially uniform phase shift to compensate for the phase shift introduced by the radial polarization converter.
