Active device for attenuating acoustic emissions for a turbojet engine including controlled turbines
Patent number: 11401866Abstract: An active device for attenuating the acoustic emissions of an aircraft turbojet engine includes circulation conduits for a pressurized air flow rate supplying rotary elements each having a pulsation system for the delivered air. The rotary elements are controlled in amplitude and phase and deliver, to outlet diffusers, a pulsed air flow rate with a pulsation at the frequency of the noise to be attenuated having an amplitude and a phase adjusted according to a local feedback law with microphones to attenuate the radiated acoustic power.Type: GrantFiled: September 8, 2020Date of Patent: August 2, 2022Assignee: Safran NacellesInventors: Jean-Paul Rami, Hervé Hurlin, Jean-Baptiste Goulard, Marc Versaevel, Philippe Micheau, Julien Drant, Ambre Allard, Alain Berry, Raymond Robert -
Publication number: 20210077759Abstract: Liquid ventilator and methods integrating the concept of total liquid ventilation (TLV) using liquid volumes below functional residual capacity (FRC) of mammal's lungs are disclosed. Beyond the automatization of the whole process, the technology has been up-scaled to confirm that TLV at residual volumes below FRC can provide a safe procedure while enabling the full potential of TLV in a mammal such as humans or adult-sized animals. Such tidal liquid ventilation strongly differs from the previously known TLV approach, opening promising perspectives for a safer clinical translation. Also disclosed are apparatus and method for safe and fast induction of hypothermia during liquid ventilation of a mammal.Type: ApplicationFiled: April 12, 2019Publication date: March 18, 2021Applicants: UNIVERSITE DE SHERBROOKE, ECOLE NATIONALE VETERINAIRE D'ALFORT, INSTITUT NATIONAL DE LA SANTÉ ET DE LA RECHERCHE MÉDICALE, UNIVERSITE PARIS EST CRETEIL VAL DE MARNEInventors: Philippe MICHEAU, Renaud TISSIER, Matthias KOHLHAUER, Julien MOUSSEAU, Mathieu NADEAU, Jonathan VANDAMME

Patent number: 10661037Abstract: A method, connector and system for obtaining an indirect measurement of a parameter in a patient with a total liquid ventilation (TLV) system. At least one parameter measurement is obtained of a liquid taken in the TLV system comprising an endotracheal tube having a distal end inserted in a patient's trachea. At least one flow measurement is obtained of a liquid taken in the TLV system. Considering a fluid model of the TLV system, the at least one parameter measurement and the least one flow measurement are processed into the indirect measurement of the parameter in the patient. The indirect measurement may be a temperature or pressure. The temperature can be a lung temperature, a blood temperature or an organ temperature. The pressure may be a tracheal pressure or an alveolar pressure.Type: GrantFiled: June 25, 2014Date of Patent: May 26, 2020Assignee: SOCPRA SCIENCES ET GÉNIE S.E.C.Inventors: Mathieu Nadeau, Philippe Micheau, Raymond Robert, Herve Walti, Olivier Avoine, Jean-Paul Praud

Patent number: 9733217Abstract: The invention relates to a method for providing a structural condition of a structure, comprising providing an excitation wave generator; providing an excitation wave sensor; injecting an excitation burst wave into the structure using the excitation wave generator; obtaining a measured propagated excitation burst wave using the excitation wave sensor; correlating the measured propagated excitation burst wave with one of a plurality of theoretical dispersed versions of the excitation burst wave; and providing an indication of the structural condition of the structure corresponding to the correlated measured propagated excitation burst wave. The method may offer a better localization of the reflection points and thus of the potential defects present in a structure under inspection, when compared with a group velocity-based or time-of-flight (ToF) approach. The method may be particularly useful for structural health monitoring (SHM) and Non-Destructive Testing (NDT).Type: GrantFiled: March 4, 2011Date of Patent: August 15, 2017Assignee: Scopra Sciences et Génie s.e.c.Inventors: Patrice Masson, Philippe Micheau, Nicolas Quaegebeur, Dominique Langlois Demers

Patent number: 7519483Abstract: The invention makes it possible to measure, in real time, the flow of a fluid that is incompressible while having an unsteady flow. The pressure measuring system is primarily comprised of a negative-pressure element (1) placed within the flow and provided with two wall pressure taps (A, B). A means (2) for measuring a pressure difference connected to the pressure taps (A, B) enables the following formula to be solved: dq(t)/dt+?(q(t))=?×?p(t) directly stemming from fundamental equations of fluid mechanics and/or: ?p(t) represents the pressure difference measured by the sensor; q(t) represents the sought volume flow rate, and; ? represents a function of the geometry of the negative-pressure element, of the fluid and of the flow q(t), the particularity of this formula being the consideration of the direction of flow in the second term of the left member of the formula.Type: GrantFiled: February 16, 2005Date of Patent: April 14, 2009Assignees: Center National de la Recherche Scientifique (CNRS), Universite de PoitiersInventors: Eric Foucault, Philippe Szeger, Janick Laumonier, Philippe Micheau
