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.

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.

A device for generating a radiofrequency plasma, which includes a supply module applying, on an output interface, an excitation signal at a setpoint frequency, adapted for generating a spark at the output of a plasma-generation resonator connected to the output interface of the power module, and a control module supplying the setpoint frequency to the power module upon a command for generating the radiofrequency plasma. The control module is configured to determine an optimal excitation frequency, to adapt the setpoint frequency to the resonance conditions of the device after formation of the spark.

Optimization of the excitation frequency of a radiofrequency plug

A method of igniting a mixture of oxidant and fuel in a combustion chamber of a combustion engine using a spark plug arranged so that it protrudes into the combustion chamber of the engine. The method includes powering the spark plug using a first alternating electrical signal of a frequency higher than 1 MHz, and second powering the spark plug using a second alternating electrical signal of a frequency higher than 1 MHz, the second power taking place after the first powering following a time delay.
