Abstract: Signal transmission and/or reception device, by contactless inductive coupling comprising at least one structure forming one or several antennas, said structure comprising a plurality of conducting links (102, 106) in at least two parallel and distinct planes, a first plurality of said conducting links forming a first conducting circuit (104, 204, 304, 404, 504, 604, 704) through which a current (I1) will circulate, and a second plurality of said conducting links forms at least one second conducting circuit (108, 208, 308, 408, 508, 608, 708), distinct from said first circuit, and through which a current (I2) will circulate, the links being arranged such that the coefficient coupling between pairs of said circuits is zero or at least less than 5% or less than 1%.

Abstract: A vibrating nano-scale or micro-scale electromechanical component including a vibrating mechanical element that cooperates with at least one detection electrode. The detection electrode is flexible and is configured to vibrate in phase opposition relative to the vibrating mechanical element. Such a component may find, for example, application to resonators or motion sensors.

Abstract: Said device comprises a substrate (44) and, on said substrate, an integrated photonic circuit (46) adapted to be coupled to at least one optical waveguide (48) which transmits a light signal (50) and for processing said signal. According to the invention, the circuit comprises two superimposed elementary integrated photonic circuits (52, 54), each of which is adapted to be coupled to a given polarisation state of the signal and to process this state. The invention applies particularly to optical telecommunications.

Abstract: A nuclear reactor including a vessel configured to hold a reactor core, a primary circuit cooling the reactor, a reactor pit in which the vessel is placed, an annular channel surrounding a lower portion of the vessel in the reactor pit, the channel configured to act as a thermal shield in normal operation and to ascend flow of a liquid in event of an accident, a reserve of liquid capable of filling the reactor pit, a reactor containment, a chamber collecting steam generated at an upper end of the reactor pit, the chamber being separate from the containment, a circulating pump capable of generating a forced convection of the liquid in the annular channel, and a lobe pump or steam piston machine or turbine for actuating the circulating pump and capable of generating forced convection by the collected steam.

Abstract: The invention relates to an apparatus and to a process for the detection and/or quantification of cesium ions Cs+ in solution in a liquid medium. The apparatus of the invention comprises: a) an electrical device comprising two electrodes and a substrate comprising at least one portion made of a semiconductor material, the electrodes being in electrical contact with said semiconductor material; and b) a device for measuring the variation of the conduction current between the two electrodes, and at least one ligand comprising at least one calix[n]arene group bonded by grafting to the semiconductor material of the substrate of the electrical device or to one of the electrodes of the electrical device. The invention finds an application in the field of the detection of cesium ions in particular.
