Patent number: 10298324Abstract: The invention relates to a free space optical communications device (10) multiplexed in wavelengths of between 400 nm and 1600 nm, said device including demultiplexing means (11) that are designed so as to separately dissociate a number n1 of wavelengths from one another, the demultiplexing means (11) including one or more detectors (110) having a number n2 of optical filters (111) and active elements (112) which correspond to the number n1 of wavelengths, each active element (112) being arranged to selectively detect one wavelength from among said wavelengths (Id . . . Àn) via an optical filter (111) separate from the active element (112) which is included in a housing (113), the optical filter (111) being in contact with a protection means (114), inserted between the optical filter (111) and the active element (112), said protection means (114) closing said housing (113).Type: GrantFiled: March 30, 2016Date of Patent: May 21, 2019Assignees: UNIVERSITÉ DE PICARDIE JULES VERNE, UNIVERSITE DE TECHNOLOGIE DE COMPIEGNE, Centre National de la Recherche Scientifique (CNRS)Inventors: Frederic Lamarque, Christine Prelle, Hani Al Hajjar, Jeremy Terrien, Andreas Zeinert

Patent number: 10264954Abstract: The invention relates to an imaging device (E) comprising: at least one generator (1) of structured light; an emission first image guide (5, 5?) for uplinking the structured light from the generator (1) to an object to be observed; and a return second image guide (5?, 5) for downlinking the light reflected by said object to be observed to a system (2) for capturing said reflected light. Each of the two image guides (5, 5?) is able to uplink the structured light and downlink the reflected light, and the imaging device comprises an optical switch (3) configurable into three different operating modes.Type: GrantFiled: December 17, 2014Date of Patent: April 23, 2019Assignees: UNIVERSITE TECHNOLOGIE DE COMPIEGNE—UTC, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS), INSTITUT NATIONAL DES SCIENCES APPLIQUEES DE LYON, ECOLE CENTRALE DE LYON, UNIVERSITE CLAUDE BERNARD LYON 1Inventors: Frederic Lamarque, Erwan Dupont, Christine Prelle, Laurent Petit, Tanneguy Redarce

Patent number: 8821107Abstract: A method of modifying a steam turbine to change from a first maximum thermal power of the steam generator to a second maximum thermal power of the steam generator. The method can include replacing, in the high-pressure module, at least one set of fixed blades sized for the first maximum thermal power by at least one set of fixed blades sized for the second maximum thermal power. The at least one set of moving blades are sized to operate at the first and second maximum thermal powers. The rotor and the at least one set of moving blades of the high-pressure module remain unchanged on changing from the first maximum thermal power to the second maximum thermal power.Type: GrantFiled: September 30, 2011Date of Patent: September 2, 2014Assignee: ALSTOM Technology LtdInventor: Frederic Lamarque

Patent number: 6158866Abstract: An optical system for presenting an image to a user. The system includes an image source and an optical channel transmitting the image to the user's eye. It also includes an illumination of the ocular fundus and an imaging of the illuminated ocular fundus, both using part of the optical channel. The system enables an analysis of the eye retina observing an image. It also enables depending on the eye position, an adaptation of the visual image presented. If the system is partially mounted in a headset, it enables the presentation of the image to a mobile user.Type: GrantFiled: October 29, 1999Date of Patent: December 12, 2000Assignee: Thomson -CSF SextantInventors: Christian Gulli, Alain Leger, Laurent Bignolles, Frederic Lamarque, Jean-Fran.cedilla.ois Le Gargasson
