A sample tray for temperature-sensitive reactions includes sample wells, floating ribs, and a frame. Each sample well corresponds to two floating ribs. The sample wells are disconnected one another in a length direction of the frame, and each sample well is connected to the rectangular frame in a width direction of the rectangular frame through two floating ribs on both sides of the sample well.

An antenna unit includes an antenna radiation element (15) and a polarization selection circuit (14). The polarization selection circuit (14) is configured to selectively convert an input signal to a first output signal (S6) and/or a second output signal (S7). The first output signal (S6) and/or the second output signal (S7) is fed to the antenna radiation element (15) so as to generate linearly polarized electromagnetic waves or circularly polarized electromagnetic waves which are radiated out by the antenna radiation element (15). The first output signal (S6) and the second output signal (S7) have a first phase difference therebetween that is fixed at a specific value between 0-180°.

A rotor-stator assembly for a rotary engine, compressor or pump, comprises a rotor (3, 4) arranged to rotate eccentrically in a stator chamber (1, 2), the geometry of the rotor (3, 4) being configured to provide a first fluid seal at a region of maximum proximity between the outer peripheral surface of the rotor (3, 4) and the inner peripheral wall of the stator chamber (1, 2), whereby a second fluid seal is provided by means of a component (15) rotating with the rotor, one end of which is permanently connected to the inner surface of the stator chamber (1, 2) by means of bearings and slides along the inner surface of the stator chamber (1, 2), and the other end of which is accommodated in a radially movable manner in a receptacle of the rotor (3, 4), the first and second fluid seals delimiting a first chamber portion and a second chamber portion of the stator chamber (1, 2).

Battery selection methods for battery exchange are provided. Batteries (112) in a battery energy station (100) are sorted in response to a battery exchange request according to SOC of each battery (112) to form candidate batteries (112). A plurality of first candidate batteries (112) having the second highest SOC are selected and provided. If the first candidate batteries (112) do not exist, a second candidate battery (112) with the highest SOC and a third candidate battery (112) with the second highest SOC are selected and provided when the difference in SOC therebetween is less than or equal to a first predetermined threshold value. When the difference in SOC is not less than or equal to the first predetermined threshold value, the second candidate battery (112) is excluded from the candidate batteries (112), and the first selection operation is re-performed.

A wireless communication capsule sensor (1) with an electronic magnetic switch (132) includes a battery (130), a microprocessor (140) and an actuation module (13). The battery (130) is electrically connected to the microprocessor (140) through an electronic magnetic switch (132) and an energy storage element (131). The actuation module (13) is electrically connected to the microprocessor (140). The energy storage element (131) stores energy using a small current outputted by the battery (130). When the microprocessor (140) is in sleep mode and the electronic magnetic switch (132) receives an external magnetic field, the electronic magnetic switch (132) outputs a trigger signal (1320) to wake up the microprocessor (140), so the microprocessor (140) uses the electrical energy of the storage element and battery (130) to drive the actuation module (13) for bio-signal detection or physical therapy. When the microprocessor (140) is in working mode and the electronic magnetic switch (132) receives the magnetic field again, the electronic magnetic switch (132) outputs a trigger signal (1320), and the microprocessor (140) stops the operation of the actuation module (13).

Sealing element which is elastically expandable when moisture is absorbed, designed to effectively support the sealing of holes that are drilled into roofs, terraces and walls for the purpose of securing constructions against moisture or water infiltration in the building material or the building itself. It is made from a hydro-expandable material, such as bentonite, or synthetic hydro-expandable TPE, mixed with a composite material possessing elastic properties. The element is produced either through mold injection of a mixture of a hydro-expandable material with a synthetic material possessing elastic properties, or through successive injection, of first a plastic material to form a plug and then of a composite material comprising a hydro-expandable material and a material possessing elastic properties.
