Abstract: A radiocommunications terminal includes a send circuit and a receive circuit connected to a send/receive antenna of the terminal and respectively defining, when in operation, a send mode and a receive mode. The terminal also includes a circuit in a common part of the connection of the send and receive circuits to the antenna for matching the send and receive circuits to the antenna. A device for controlling and monitoring the power of signals sent/received by the terminal decenters the impedance matching of the antenna of the terminal only when the device is in send mode. Applications include reducing the energy impinging on the user of a mobile radio communications terminal.

Abstract: The invention relates to watches, generally wristwatches, whose cases incorporate electronic modules for storing information that comprise an integrated circuit connected to an antenna consisting of a coil and are able to communicate by radio signals with a reading and/or writing device adapted at least to read the information contained in a memory of the integrated circuit and often also adapted to delete or modify at least some of that information and to add other information. To eliminate the drawbacks of prior art watches in which the module is inside the case (complicated fabrication or new design of the watch, increased volume thereof) or to reduce the importance of those drawbacks (attenuation and/or distortion of the signals sent and received by the coil), in the watch of the invention the electronic module (14) is housed at least for the most part in a cavity (13) in the back (3) of the case (1) open towards the outside.

Abstract: A telephone includes a body carrying an earpiece at one end and a flap at the other end integrating a microphone or reflecting sound towards a microphone. The flap can be foldable between a position to receive the sound of the voice and a folded position to reduce the overall size of the telephone when it is not in use or is on standby. The battery inserts in a cavity of a base of the flap so that when fitted it is integrated into the flap. Its use reduces the overall thickness of the telephone and makes it easier to handle.
