Abstract: A system for hands-free access to a vehicle includes a hands-free access device that transmits a location frame of a modulated signal and a pure carrier signal, receives a measurement of a received signal strength of a primary received signal performed on the pure carrier signal by a hands-free identifier, and receives information on an absence or presence of noise in the location frame. Additionally, the hands-free access device authorizes or prevents access to the vehicle. The system further includes a hands-free identifier that receives the location frame, performs a measurement of the received signal strength of the primary received signal on the pure carrier signal, sends the hands-free access device the measurement of the received signal strength of the primary received signal, checks the presence of noise in the location frame, and sends the hands-free access device information on the absence or presence of noise in the location frame.

Abstract: The invention relates to a closing-in or presence or detection capacitive sensor (6) for locking/unlocking a door leaf (4), in particular for a vehicle. More precisely, the closing-in capacitive sensor is to be integrated into the handle (1) of a door leaf for locking/unlocking the same. The sensor includes at least one electrode and at least one metal shielding member (10) formed on a printed circuit (8) so as to create a detection area (5) for detecting the presence of a user.

Abstract: The easy direction of magnetization of an amorphous magnetic film is brought in the plane of the film by annealing this film in an oxygen-free atmosphere composed of a gas selected from the group comprising argon, neon, krypton and xenon at a temperature below the temperature of crystallization of the alloy which constitutes the film. The depth of penetration of the rare gas into the film is adjusted by modifying the parameters of annealing temperature and time in order to modify the easy direction of magnetization to a greater or lesser depth within the film.
