Patent number: 9437199Abstract: The invention relates to a method and the associated device 1 for separating one or more particular digital audio source signals (si) contained in a mixed multichannel digital audio signal (smix) obtained by mixing a plurality of digital audio source signals (s1, . . . , sp). According to the invention: the modulus of the amplitude or the normalized power of the particular source signal(s) (si) is determined from representative values of said particular source signal(s) contained in the mixed signal; and then linearly constrained minimum variance spatial filtering is performed on the mixed signal in order to obtain each particular source signal (s?i), said filtering being based on the distribution of said particular source signal between at least two channels of the mixed signal, and the modulus of the amplitude or the normalized power of said particular source signal is used as a linear constraint of the filter.Type: GrantFiled: September 25, 2013Date of Patent: September 6, 2016Assignees: UNIVERSITÉ BORDEAUX 1, CENTRE NATIONAL DE LAS RECHERCHE SCIENTIFIQUE (CInventors: Sylvain Marchand, Stanislaw Gorlow

Publication number: 20140070114Abstract: A method for 3D recording of data on a medium formed from a transparent photosensitive material including at least one dopant. The method includes a first step of calibrating and checking a pulsed light source including calibrating the number of pulses, the level of fluence of each pulse emitted and the rate of the pulses and a step of inscribing an area of the material. The fluence of each pulse emitted, the number of pulses and the rate of the pulses are suitable for irradiating the material in the area so as to form fluorescent clusters stabilized from the dopant while minimizing the modification of the refractive index and the absorption coefficient of the medium in a wavelength range from visible to near infrared.Type: ApplicationFiled: November 14, 2013Publication date: March 13, 2014Applicant: UNIVERSITE BORDEAUX 1Inventors: Lionel Stephane Canioni, Thierry Cardinal, Bruno Bousquet, Arnaud Royon, Matthieu Bellec, Kevin Bourhis, Gautier Papon, Philippe Legros
