  • Patent number: 10862194
    Abstract: An electrical device includes an electronic control unit including a radio communication interface provided with a planar internal radio antenna housed inside a first housing of the electrical device and including a first radiating element. The electrical device furthermore includes a movable coupling element connected to an external radio antenna, the coupling element being provided with a second radiating element and being able to be moved between a position connected to the housing of the electrical device and a position disconnected from the housing. In the connected position, the coupling element is positioned facing the internal radio antenna while being separated therefrom by an electrically insulating element, the second radiating element being coupled to the first radiating element so as to receive electromagnetic radiation emitted by the first radiating element.

  • Patent number: 10448395
    Abstract: A method of radio communication in a system including a plurality of communicating modules, each communicating module being able to obtain at least one measured physical value and to transmit a message encapsulating at least one measured physical value to a hub device according to a given radio communication protocol, the sending of the message being performed during a communication time interval, defined by a start instant and an end instant, a waiting time separating two successive communication time intervals of one and the same communicating module. For each communicating module of the plurality of communicating modules, the waiting time is calculated as a function of an updated counter of the communicating module as a function of a receipt of an acknowledgement message originating from the hub device.
