Patent number: 11593381Abstract: Pre-computed query results stored at a database server are re-computed by a computation machine. The pre-computed query results are composed of a plurality of shares. Each share includes a certain number of pre-computed query results. The computation resources of the computation machine needed to re-compute a pre-computed query result of a first share depend on whether or not other pre-computed query results of the first share are re-computed during a given time interval forming a current re-computation cycle. The computation machine receives a request to re-compute pre-computed query results of at least a first share, determines a number of pre-computed query results in the first share to be re-computed in the current re-computation cycle based on a Reinforcement Learning algorithm, and re-computes the determined number of pre-computed query results in the first share.Type: GrantFiled: January 25, 2018Date of Patent: February 28, 2023Assignee: Amadeus S.A.S.Inventors: Jean-Philippe Aubry, Guillaume Le Grand, Johann Marchi, Nicolas Legrand

Publication number: 20210078060Abstract: A flatness roller includes a body having at least one cavity opening onto an outer surface of the body through a plurality of slots, two successive slots defining a lamella between them, each lamella being connected to the body by two connection portions. The flatness roller also includes at least one optical fibre having at least one strain sensor having a measurement axis. Each strain sensor is housed in a cavity and attached at a connection portion of a lamella, the measurement axis forming an angle less than or equal to 20° with a plane orthogonal to the axis of revolution of the body. Each strain sensor is configured to send an optical response wave representative of a strain of the strain sensor according to the measurement axis thereof.Type: ApplicationFiled: February 19, 2019Publication date: March 18, 2021Applicants: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES, ArcelorMittalInventors: Sylvain MAGNE, Nicolas LEGRAND

Patent number: 9795862Abstract: A toe-piece for binding a boot to a gliding board, the toe-piece including a frame; two wings each pivotable in relation to the frame about an axis of rotation and supporting a lateral interface surface designed to come into contact with a front portion of the boot when the toe-piece is in a descent configuration. The toe-piece further includes a lateral release mechanism that includes a connecting element connected to the wings such that the displacement of the connecting element causes the rotation of the wings about their axes of rotation; a first elastic member, a first end of which is connected to the connecting member; and a body against which a second end of the first elastic member presses.Type: GrantFiled: April 8, 2015Date of Patent: October 24, 2017Assignee: SALOMON S.A.S.Inventors: Daniel Soldan, Nicolas Legrand, Alain Berthet

Patent number: 9220969Abstract: A toe-piece for binding a boot to a gliding board, the toe-piece including a first front boot-retaining device and a second front boot-retaining device. The first front boot-retaining device is designed for ascending a slope and includes boot-fastening mechanisms defining a hinge axis about which the boot pivots when the toe-piece is in an ascent configuration. The second front boot-retaining device is designed for descending a slope and includes two wings each supporting a lateral interface surface designed to come into contact with a front portion of the boot when the toe-piece is in a descent configuration. The toe-piece also includes a longitudinal stop surface movable between an active position in which it is designed to cooperate with the front portion of the boot, and an inactive position in which it is arranged so that it is no longer capable of cooperating with the front portion of the boot. The longitudinal stop surface is movable in relation to the wings.Type: GrantFiled: April 8, 2015Date of Patent: December 29, 2015Assignee: SALOMON S.A.S.Inventors: Daniel Soldan, Nicolas Legrand, Alain Berthet
