  • Publication number: 20230271160
    Abstract: A method of checking the storage and the radioactive activity of a radioactive gas adsorbed by a porous material having scintillation properties, which comprises: (a) putting the porous material in place in an enclosure, (b) performing circulation of the radioactive gas in the enclosure, (c) monitoring the adsorption of the radioactive gas by monitoring the scintillation of the porous material, up to an adsorption level, (d) interrupting the radioactive gas circulation in the enclosure when the adsorption level is attained, (e) placing the enclosure under a vacuum, and (f) monitoring the radioactive activity of the radioactive gas adsorbed by the porous material at the end of step (c) by monitoring the scintillation of the porous material. The porous material comprises metal organic frameworks formed of inorganic sub-units constituted by Zn4O and an organic ligand.

  • Patent number: 11401462
    Abstract: Hybrid material for plastic scintillation measurement comprising: a polymeric matrix; and a fluorescent mixture incorporated in the polymeric matrix and comprising, with respect to the total number of moles of primary fluorophore in the incorporated fluorescent mixture, i) from 95.6 molar % to 99.6 molar % of a main primary fluorophore consisting of naphthalene and ii) from 0.4 molar % to 20 molar % of an additional primary fluorophore. The decay constant of the fluorescence of the hybrid material is intermediate between that of a fast plastic scintillator material and of a slow plastic scintillator material. Further, they can be chosen over a wide range. The invention also relates to an associated part, device and item of equipment, to their processes of manufacture or their methods of measurement.

  • Patent number: 11104586
    Abstract: The present invention describes a liquid recycling system and method for purifying and either recirculating or discarding of liquid. The system includes a liquid input line, a tank, and a circulation pump for providing recirculation of liquid from the tank. A filter and a heater are used to treat liquid from the circulation pump. A valve is provided to direct liquid either to a shower head or faucet, or back to the tank. Additional plumbing and components can be used to provide multiple independent recirculation loops with the tank. An electronic controller can be used to control components of the present invention, where a user could interface with the controller via a control panel or a software application accessed by a portable electronic device.

  • Publication number: 20190331809
    Abstract: Material for plastic scintillation measurement comprising: —a polymeric matrix; —a primary fluorophore incorporated in the polymeric matrix and composed of N-(2-ethylhexyl)carbazole, the monomer form of the N-(2-ethylhexyl)carbazole being spontaneously in physicochemical equilibrium with the exciplex form; and, —a secondary fluorophore. A plastic scintillator can be manufactured in a simplified manner with the material of the invention, while having optimized properties for the plastic scintillation measurement. The invention also relates to the process for the manufacture of the material, to a part comprising the material and to the associated measurement device, and also to the process for measurement by plastic scintillation using the material.

  • Patent number: 9847349
    Abstract: An integrated electronic device is supported by a substrate of a silicon on insulator type. At least one transistor is formed in and on a semiconductor film of the substrate. The transistor includes a drain region and a source region of a first conductivity type and a substrate (body) region of a second conductivity type lying under a gate region. An extension region laterally continues the substrate (body) region beyond the source and drain regions and borders, in contact with, the source region through a border region having the first conductivity type. This supports formation of an electrical connection of the source region and the substrate (body) region.

  • Patent number: 8375150
    Abstract: Various exemplary embodiments relate to a High-Definition Multimedia Interface (HDMI) switch configured to receive notification of a switch from a current HDMI source to a new HDMI source, determine whether the new HDMI source is actively transmitting data, has attempted to access an HDCP register before a predetermined timeout delay since a last HDCP register access, and is transmitting unencrypted data, and based on these determinations, either immediately begin transmission of the HDMI data received from the new source or reset the new HDMI source. In this manner, various exemplary embodiments enable switching between HDMI sources with a reduced delay.
