Alexandre CAUSIER has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10365236
    Abstract: There is provided a Nuclear Magnetic Resonance (NMR) measurement cell for use with a solution enabling the introduction of a gas into said solution. The measurement cell includes at least a detection volume designed to be installed in a static magnetic field of an NMR spectrometer, and includes in said detection volume, a gas introduction zone, a measurement chamber for the solution at a distance from the gas introduction zone and a network of conduits for the solution formed to set up fluid communication between the gas introduction zone and the measurement chamber. The gas introduction zone includes at least one gas inlet in the network of conduits, to generate bubbles in the gas introduction zone only. There is also provided a method of manufacturing such a measurement cell and a measurement assembly including such a measurement cell.
    Type: Grant

  • Patent number: 8900907
    Abstract: A method for removing the growth substrate of a circuit of electromagnetic radiation detection, especially in the infrared or visible range, said detection circuit including a layer of detection of said radiation made of Hg(1-x)CdxTe obtained by liquid or vapor phase epitaxy or by molecular beam epitaxy, said detection circuit being hybridized on a read circuit. The method includes submitting the growth substrate to a mechanical or chem.-mech. polishing step or to a chemical etch step to decrease its thickness, all the way to an interface area between the material of the detection circuit and the growth substrate; and submitting the interface thus obtained to an iodine treatment.
