Publication number: 20230112155Abstract: A sensor for detecting a volatile compound or gas. The sensor includes a transducer having: a planar resonator including a plurality of metal tracks, on a printed circuit, of the coplanar type; and a sensitive layer deposited on a predetermined portion of the resonator. The sensitive layer is configured so that the presence of a volatile compound or of a gas to be detected implies a modification of the permittivity of the sensitive layer resulting in a modification of the features of the sensor during its electrical power supply.Type: ApplicationFiled: March 1, 2021Publication date: April 13, 2023Inventors: Antoine Denis, David Rondeau, Mohamed Himdi, Xavier Castel, Stéphane Cordier

Patent number: 6607168Abstract: The bearing structure such as a wing is fitted with toothed platelets (16) at its free edges to break tip vortex produced at these places by fluid pressure distribution. Vortex dissipation is accelerated, vortex remanence is considerably reduced. In the case of a deflector for a line of hydrophones (30) towed by a ship (31) to carry out seismic tests at sea, the noise disturbing the hydrophones (30) is reduced. In the case of marine applications, risks of cavitation are much reduced, particularly with regard to stabilizers or propellers. In the case of aeronautics applications, vortex remanence on take-off and on landing of planes is reduced.Type: GrantFiled: May 16, 2001Date of Patent: August 19, 2003Assignees: Geco AS, Francais, EtatInventors: Stéphane Cordier, Laurence Briancon-Marjollet
