Patent number: 11809488Abstract: A method for generating for a subject a personalized playlist of sounds, notably songs, using the analysis of the subject's electroencephalographic signal, the method including the following steps: receiving at least one segment of electroencephalographic signal acquired from at least one electrode while the subject is listening to at least one proposed sound; extracting at least one EEG index from the electroencephalographic signal segment so as to characterize brain patterns correlated to the emotions evoked by the music and the level of appreciation of the sound; evaluating the valence of sounds listening on the basis of the EEG index; receiving a score of appreciation on the sound from the subject; including the sound in the personalized playlist (P) of the subject whenever the valence matches a predefined valence and/or the score of appreciation is higher than a predefined threshold.Type: GrantFiled: July 7, 2020Date of Patent: November 7, 2023Assignee: MYBRAIN TECHNOLOGIESInventors: Audrey Breton, Yohan Attal

Publication number: 20220265221Abstract: A method for monitoring physiological signals of a subject from sounds produced by the subject, including: receiving recorded sounds, including sounds from the subject's chest and being transmitted by the subject's biological tissues to the subject's ears, the recorded sounds being recorded by sound recording element(s) positioned inside earcup(s) of headphones worn by the subject; receiving signals from an accelerometer and a gyroscope being recorded simultaneously with the recorded sounds; detecting heart beats from the cardiac peaks sounds and calculating inter-beat intervals from the heart beats; extracting a first estimation of the breathing signal from the inter-beat intervals presenting respiratory sinus arrhythmia; extracting a second estimation of the breathing signal from residual sounds; extracting a third estimation of the breathing signal and motion artifacts from the signals of the accelerometer and the gyroscope; calculating the breathing signal by combining the first, second and third estimatiType: ApplicationFiled: September 17, 2020Publication date: August 25, 2022Applicant: MYBRAIN TECHNOLOGIESInventors: Xavier NAVARRO-SUNE, Nicolas POURCHIER, Fabrice VAILHEN, Yohan ATTAL
