Patent number: 10859378Abstract: An iterative method for determining scattering coefficients of the cavity of a laser gyro in operation supporting two counter-propagating modes, comprises steps of: determining a set of variables dependent on characteristic physical quantities of the laser gyro, one reference variable per dependency relationship being selected from the variables; measuring values of the characteristic physical quantities of the laser gyro in operation; determining measured values of the variables; estimating, via an iterative method, estimated values of the coefficients minimising a discrepancy between the measured values of the reference variables and estimated values of the reference variables, which are estimated from the values of the coefficients and the measured values of the variables other than the reference variables; and determining estimated values of the scattering coefficients from the estimated values of the coefficients.Type: GrantFiled: March 8, 2017Date of Patent: December 8, 2020Assignees: THALES, ASSOCIATION POUR LA RECHERCHE ET LE DÉVELOPPEMENT DE MÉTHODES ET PROCESSUS INDUSTRIELS-ARMINESInventors: Noad Hamze El Badaoui, Pierre Rouchon, Gilles Feugnet, Sylvain Schwartz, Philippe Martin

Patent number: 8915315Abstract: A drillpipe for a drill stem to drill a hole. The drill stem includes a drill string and a bottom hole assembly. The drillpipe includes a first end having a first inertia, a second end having a second inertia, a first intermediate zone adjacent to the first end, a second intermediate zone adjacent to the second end, and a central substantially tubular zone with an external diameter smaller than the maximum external diameter of at least the first or the second end. A casing is fixed on the pipe over a portion of the external surface thereof, at least one physical parameter sensor is disposed in the casing, and at least one data transmission/storage mechanism is connected to the sensor output, the casing being disposed at a distance from the first and second ends, the casing being integral with the central zone at a distance from the first and second intermediate zones and having a smaller inertia than the first and second inertias.Type: GrantFiled: July 20, 2010Date of Patent: December 23, 2014Assignees: Vam Drilling France, Association Pour la Recherche et le Developpement de Methodes et Processus IndustrielsInventors: Jean Boulet, Stéphane Menand

Publication number: 20120174623Abstract: The invention provides a method and a system for extracting a substance comprised in a gaseous mixture, the extraction being carried out in a cyclic manner in 2N chambers (AA, BB, CC, DD), each provided with a heat-exchanger (A, B, C, D), N being an integer greater than or equal to 3. Each chamber carries out a cycle comprising the following four steps in succession: a frosting step, a defrosting step, a step of recovering the liquid phase and the residual gas phase, and a temperature-reduction step of reducing the temperature of the heat-exchanger. Further, sequencing the passage from one step to another in each of the chambers is such that the number of chambers carrying out the frosting step and also the total number of chambers carrying out the defrosting, recovery, and temperature-reduction steps are both equal to N.Type: ApplicationFiled: August 9, 2010Publication date: July 12, 2012Applicant: ASSOCIATION POUR LA RECHERCHE ET LE DEVELOPPEMENT DE METHODES ETInventors: Denis Clodic, Mourad Younes, Yousseff Riachi, Elias Bou Lawz Ksayer
