Patent number: 11906422Abstract: The invention relates to a device for detecting a gaseous species by photoacoustic effect. The device comprises a substrate, inside which a cavity is formed. A light source is disposed on the substrate, in such a way that a part of the substrate extends between the light source and the cavity. The device is arranged in such a way that the light, emitted by the light source, is propagated through the substrate, before reaching the cavity.Type: GrantFiled: November 25, 2022Date of Patent: February 20, 2024Assignee: Commissariat à l'Energie Atomique et aux Energies AlternativesInventors: Emmanuel Ollier, Caroline Coutier, Laurent Duraffourg, Thierry Verdot

Publication number: 20160109348Abstract: A measurement system of a tangential force applied by a fluid is provided. The system includes a pipe in which the fluid flows, the pipe includes an inner surface contacting the fluid, and a cavity arranged in the inner surface of the pipe: and a MEMS and/or NEMS device measuring the tangential force including a support, a moving plate suspended from the support by a pivot link, the moving plate including a first face on which the fluid applies a tangential force. The device is fixed to the pipe such that the first face of the moving plate is flush with the inner surface of the pipe. The device includes two piezoresistive strain gauges suspended between the moving plate and the support, the tangential force applying force to the gauges.Type: ApplicationFiled: October 16, 2015Publication date: April 21, 2016Applicant: Commissariat a l'energie atomique et aux energies alternativesInventors: Philippe ROBERT, Caroline COUTIER

Patent number: 7724111Abstract: A microsystem, including a magnetic microactuator, with a mobile element supported by a substrate and controlled by magnetic effect between a first position and a second position for switching at least one electric circuit. A permanent magnet or a solenoid subjects the mobile element to a first uniform magnetic field to hold the mobile element in the first position. An energizing coil external to the substrate, on energizing, subjects the mobile element to a second magnetic field to move the mobile element from the first position to the second position, the energizing coil being of solenoid type and surrounding the substrate supporting the mobile element.Type: GrantFiled: January 6, 2006Date of Patent: May 25, 2010Assignee: Schneider Electric Industries SASInventors: Sylvain Paineau, Caroline Coutier, Amalia Garnier, Benoît Grappe, Laurent Chiesi
