Patent number: 11959953Abstract: A device is suitable for revealing spatial variations in polarization of an electromagnetic radiation, in a form of localized temperature variations. The device includes a surface of a carrier which is electrically and thermally insulating, and includes an array of patterns which each consist of at least one rectilinear segment of a sensitive material, of which the orientation is variable within each pattern or between neighboring patterns. Such device may be used with a thermal camera to reveal, in infrared images, temperature variations which are localized at segments not perpendicular to a local direction of linear polarization of the radiation.Type: GrantFiled: September 16, 2020Date of Patent: April 16, 2024Assignees: OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AÉROSPATIALES, CENTRE NATIONAL D'ETUDES SPATIALES C N E S, UNIVERSITE TOULOUSE III—PAUL SABATIER, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE—CNRSInventors: Daniel Prost, Maxime Romier, Daniel Belot, Patrice Simon, Kévin Brousse, Pierre-Louis Taberna

Patent number: 10684329Abstract: A method for estimating the ageing of a battery powering an electrical system. A set of data about the voltage and current across the battery terminals, in response to the current perturbations provoked during the normal operation of the battery by the changes of consumption rate of the electrical system are stored. The impedance of the battery, within a predetermined frequency interval, from the voltage and current data is determined. The age of the battery as a function of the impedance is estimated by comparing the impedance with a previously stored model of evolution of this impedance with ageing.Type: GrantFiled: August 9, 2013Date of Patent: June 16, 2020Assignees: AIRBUS DEFENCE AND SPACE SAS, CENTRE NATIONAL D'ETUDES SPATIALES CNESInventors: Laurent Gajewski, Pierre-Louis Taberna, Patrice Simon
