Abstract: A capsule configured for collecting samples in the intestine, comprising a body delimiting at least one compartment for receiving samples and comprising at least one opening for samples intake, and a mobile mechanism for opening and/or closing the opening controlled by the dissolution of a material which is dissolvable in the intestine.

Abstract: Two detectors mounted on footprints (12) and (13) of a plate (5) can be permuted and placed in turn in front of a measuring location set in a plate (1) connected to the plate (5). Concentric sealing joints (24, 25) bound with the plates (1, 5) a closed cavity wherein a vacuum should be created to perform measurements. The joints enable the plate to be mutually moved without sealing loss. The invention is however applicable to any device implying a relative displacement of two parts in front of each other, a stronger pressure existing outside of the parts than between them, which tends to collapse them against each other.

Abstract: The invention relates to an impedance-matching device comprising a circuit consisting of a plane substrate (27) whereon at least one conductive stripline (26) is arranged, at least one conductive spring (22) applying mechanical stress on the circuit.

Abstract: An energy conversion system, including a first and second electrodes with an inter-electrode gap therebetween that includes a functional medium, wherein the first electrode is made of at least one elongate electrically conductive media having a total length L, a curved cross-section, and a radius R, and arranged into a sturdy assembly structure having a more or less open pattern, capable of having the same electric potential at any location and thus of constituting said first electrode. Where R is lower than 40×10-6 m the inter-electrode gap has a thickness of between 1×10-9 m and 5×10-3 m, the total length L of the electrically conductive media of the first electrode is greater than 1×103 m, and the ratio L/R is greater than 106 such that the first electrode generates a significant increase in the electric field perceived by the second electrode.
