20120296570 | DEVICE AND METHOD FOR MULTIPARAMETER MEASUREMENTS OF MICROPARTICLES IN A FLUID - The invention relates to a method of classifying and flow measuring the refringence of at least two populations of particles present in a fluid. The method uses a light source that has small coherence time, with a coherence length Lc<100 μm, that is used under extinction conditions at a center wavelength selected as a function of a range of volumes and of a range of refractive indices expected for the particles under consideration. The method uses a device that, together with the light source, forms a converging illuminating beam of aperture angle that is selected as a function of the range of volumes and the range of refractive indices expected for the particles under consideration at the selected center wavelength. | 11-22-2012 |

20150241352 | Method for Compensating for the Aging of a Reagent During Fluorescence Measurements Carried out on Particles, and Biological Analysis Device Implementing the Method - The present invention relates to a method for compensating for the breakdown of a reagent stored in an aqueous phase comprising at least one fluorescent compound and enabling the identification of particles, including the steps of: (i) measuring the fluorescence level FLUOm(t) of particles marked with said reagent; (ii) measuring the absorbance at at least one wavelength of a solution of said reagent, at a time t close to the time of said fluorescence level FLUOm(t) measurements, so as to determine at least one current optical density DO(t) of the reagent; and (iii) calculating a correction of the fluorescent level measurements using said at least one current optical density DO(t) and at least one initial optical density DO(0) of the reagent that has not been broken down. The invention also relates to a biological analysis device implementing the method. | 08-27-2015 |

20120002121 | VARIABLE CONTRAST, WIDE VIEWING ANGLE LCD LIGHT-SWITCHING FILTER - A new concept of the LCD light-switching optical filter allowing for very high, electrically controlled, continuously variable light attenuation (up to ≧100,000) optimized/symmetrized for the light incidence along the normal to the LCD plane is proposed. The new LCD light-switching optical filter also exhibits very low light attenuation dependence for the oblique incidence of light within a limited cone of angles off the normal incidence direction in compliance with the international safety and quality regulation EN 379 for personal protection equipment. According to the invention the problem is solved by specific, novel modification of the general principle of highly twisted nematic LCDs, allowing for the adaptation of the light transmission/driving voltage characteristics to specific requirements of the driving electronics as well as “symmetrizing” the overall optical birefringent properties, which in turn results in a high degree of their angular compensation. | 01-05-2012 |

20140097809 | REACTIVE POWER COMPENSATOR - A reactive power compensator for a three-phase network having first, second and third phases includes an assembly of capacitors and electromechanical contactors electrically connected to the capacitors. Each contactor includes at least one upstream and one downstream power terminal. An electric current circulates between the upstream and downstream power terminals when the contactors are closed. A first contactor is connected to the first phase and a second contactor is connected to the third phase. The voltage between the upstream and downstream power terminals of at least one electromechanical contactor is measured so that the electromechanical contactors can be controlled according to a control algorithm. The control algorithm includes the closure of a contactor for a substantially zero voltage between the upstream and downstream power terminals thereof, and the opening a contactor for a substantially minimum power value of the capacitors to which the contactor is connected. | 04-10-2014 |
