Patent number: 11344985Abstract: Machining tool comprising a frame in which a drive shaft for a tool is mounted so as to pivot about a rotation axis and to move axially along the rotation axis. The shaft is connected to two rotary motors, namely a first motor connected to a member for meshing with a fluted portion of the shaft in order to drive the shaft in rotation and a second motor connected to a nut engaged with a threaded portion of the shaft in order to move the shaft axially. The motors are connected to at least one control unit designed to control the motors independently of one another, and the first motor and the second motor are coaxial with one another.Type: GrantFiled: March 16, 2020Date of Patent: May 31, 2022Assignees: AMVALOR, ADVANCED ENGINEERING & INNOVATIONInventors: Georges Moraru, Didier Frangeard

Patent number: 10780331Abstract: Some embodiments are directed to an analysis device for board sports, intended to be secured to a board, such as a surfboard or ski, at the interface with the user. The device includes: a force sensor designed to capture one or more forces generated by the user on the board; a position and motion sensor designed to capture the position, speed and acceleration of the board in space; and a processing unit or processor connected to the force sensor and to the position and motion sensor and designed to synchronize and process the data from the sensors.Type: GrantFiled: June 29, 2016Date of Patent: September 22, 2020Assignees: UNIVERSITÉ DE BOURDEAUX, INSTITUT POLYTECHNIQUE DE BORDEAUX, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, ÉCOLE NATIONAL SUPÉRIEURE D'ARTS ET MÉTIERS (ENSAM), AMVALORInventors: Kévin Lestrade, Jean-Luc Barou, Philippe Viot, Sandra Guérard, Patrick Lanusse

Patent number: 10478141Abstract: A method of estimating the distribution of bone mineral density in at least one portion of a person's skeleton. The method includes generating a geometrical representation of the portion of the skeleton; a geometrical representation in three dimensions of at least one portion of the outline of the person; and first and second X-ray images; and using software to estimate: a value for the thickness of soft tissue through which the given X-ray has passed; an attenuation coefficient of the soft tissues that have been passed through; a value for the thickness of bone tissue through which the given X-ray has passed; and using the thickness value for the soft tissue through which the given X-ray has passed, and a value for the attenuation of the given X-ray due to the thickness of the bone tissue through which it has passed, the software estimates a value representative of the bone mineral density of the bone tissues through which the given X-ray has passed.Type: GrantFiled: May 4, 2016Date of Patent: November 19, 2019Assignees: AMVALOR, ECOLE NATIONALE SUPERIEURE D'ARTS ET METIERSInventor: Wafa Skalli

Patent number: 10207334Abstract: A machining device including a framework, a transmission shaft and a drive mechanism including a rotation member for driving the shaft in rotation about its axis, a drive member in helical connection with the shaft to drive the translation thereof along its axis with a feed movement, according to the relative rotational speed of the rotation and drive members. The drive member is mounted with the ability to effect translational movement with respect to the framework along the axis and is positioned between the rotation member and an end for coupling of the shaft to a cutting tool, while an electromechanical actuator is mounted in a fixed frame of reference associated with the framework in front of the drive member to which it can be coupled in order to cause it to oscillate translationally so as to superpose an axial oscillation component with the feed movement.Type: GrantFiled: October 20, 2015Date of Patent: February 19, 2019Assignees: CENTRE TECHNIQUE DES INDUSTRIES MECANIQUES, AMVALORInventors: Ugo Masciantonio, George Moraru

Patent number: 9925598Abstract: A machining device including a casing, a transmission shaft (3) and a drive mechanism (1) including a first gearing member (13) that is able to rotate the shaft about its axis (A), a second gearing member (17) that is in a helicoidal connection with the shaft in order to drive the shaft translationally along its axis in a feed movement, depending on the relative rotational speed of the first and second gearing members, and means for generating axial oscillations. The second gearing member (17) is able to move translationally along the axis (A) with respect to the casing, the means for generating axial oscillations including an electromechanical actuator (20) mounted at a fixed location, connected to the casing, and able to be coupled axially to the second gearing member (17) in order to make it oscillate translationally, so as to superimpose an axial oscillation component on said feed movement.Type: GrantFiled: June 5, 2014Date of Patent: March 27, 2018Assignees: CENTRE TECHNIQUE DES INDUSTRIES MECANIQUES, AMVALORInventors: Ugo Masciantonio, George Moraru
