A method for detecting the presence of a liquid in a container by a near-field communication circuit that includes at least one coil surrounding the container. The method being designed to adopt a first communication mode, in which the circuit can communicate with a compatible object arranged in the container, and a second detection mode for detecting a liquid. The second detection mode including the following steps: measuring at least one so-called present physical quantity by the coil of the circuit, the present physical quantity being representative of the dielectric permittivity of the medium bounded by the container, and transmitting a signal indicating detection of a liquid in the container if the present physical quantity crosses a predetermined reference threshold.

Method for detecting the presence of a liquid in a container by means of a near-field communication circuit

A device for activating a vehicle function. The device being intended to be housed on board a vehicle and includes at least one ultra-wideband communication antenna and at least one near-field communication antenna in order to communicate with an item of portable equipment carried by a user. The function being activated based on a location of the item of equipment with respect to the vehicle and on an authentication of the item of equipment. The windings of the near-field communication antenna delimit a perimeter of a receptacle in which the ultra-wideband communication antenna is located.

Device for activating a vehicle function

A communicating device for a motor vehicle, including a control printed circuit board, a first antenna, called 'external' antenna, including two groups of windings each arranged around one of the ends of the control printed circuit board, symmetrically with respect to an orthogonal plane, a second antenna, called “internal” antenna, including two groups of windings each arranged around the control printed circuit board between the windings of the first antenna and symmetrically with respect to the orthogonal median plane.
