Abstract: The invention concerns: a method including a step of defining an acoustic transmission frequency according to the admittance of an acoustic generator; an acoustic transmitter including the acoustic generator, configured to define said acoustic transmission frequency according to the admittance of the generator; and an acoustic receiver configured to receive an acoustic transmission signal having said transmission frequency.

Abstract: A locating device for determining a distance of an RFID tag with respect to an interface between two media comprising an inductive coupling antenna and a sensor for determining a distance between the antenna and the interface. There is an energizing circuit configured to energize the antenna to generate an electromagnetic field with various successive amplitude values and a detection device for detecting an electromagnetic field response from the RFID tag. There is a processing circuit configured to determine several pairs of information, each pair including: a distance between the antenna and the interface and a minimum electromagnetic field value detected by the detection device from the RFID tag at the determined distance between the antenna and the interface. The processing circuit also evaluates the distance between the RFID tag and the interface as a function of the several pairs.

Abstract: The invention relates to a chain including multiple microelectronic chip elements that are connected to a wire. The wire has notches that define preferred breaking points when the wire is subject to tensile stress. If the wire is conductive, the notches can be spread so that the length of the wire between a chip element and a notch is equal to the length of an antenna.

Abstract: A device and method for measuring rotation, the device including at least one ball, each ball being magnetized or having a temporary magnetization so as to present a dipole magnetization. The ball is free in rotation in a receptacle of a frame, the device including detection means of a magnetic field created by said at least one ball, along at least three non-coplanar axes of different directions.
