Title: Compensation spectrale de bruit destinee a l'annulation d'echo
Inventor: GENTER ROLAND E
IPC: H04M9/08
Filed: 1996-07-03
Granted: 2008-12-16
Abstract: Un annulateur d'écho (10) comprend une batterie de filtres d'analyse (24) chargéee de diviser un signal d'entrée émis (Si) et un signal d'entrée reçu (Ri) en signaux d'entrée reçus à sous-bandes (RC1-RC16). Chaque signal d'entrée reçu à sous-bandes (RC1-RC16) est convolutionné avec une fonction de réponse impulsionnelle propre au trajet d'écho couplant le signal reçu au signal d'entrée émis dans chaque sous-bande, pour fournir des signaux d'écho estimés (EC1-EC16) dont chacun est alors soustrait du signal d'entrée émis à sous-bandes qui correspond, ce qui produit des signaux d'erreur (ER1-ER16). Des composantes d'écho résiduelles présentes dans ces signaux d'erreur sont atténuées par un atténuateur variable (36 a-p), et une composante d'écho est injectée dans chaque signal à erreur atténuée pour compenser l'atténuation du bruit de fond due à l'atténuation variable des signaux d'erreur.

Abstract: L'invention concerne un procédé et un appareil pour appliquer avec précision une corde (12) sur un mandrin (14) rotatif. Cet appareil utilise la commande de la longueur de la corde comme paramètre de commande, et non pas la tension de la corde. L'appareil comprend un mandrin (14) sur une surface extérieure duquel est fixée une membrane gonflable (54). Cette dernière (54) peut être gonflée, de manière sélective, à l'aide d'une vanne de commmande (58) et d'une source de fluide sous pression pour ajuster dynamiquement une circonférence du mandrin (14) lors de l'entrée d'une commande. Cette dernière lit une tension dans la corde (12) en train d'être enroulée. La corde (12) est fournie de manière appropriée au mandrin (14) en fonction d'un algorithme défini à partir de la forme, de la circonférence et de la vitesse de rotation du mandrin et non pas de l'avance de la corde (12). Cet appareil comporte un cabestan d'entraînement (18) à commande électronique. Il comprend, en outre, une roue de dépose (30) de la corde qui isole les forces dirigées dans le sens radial des forces dirigées dans le sens de la circonférence. Selon un deuxième mode de réalisation, la courroie est entraînée en rotation par des première et deuxième poulies (14A, 14B) tandis que la corde (12) est appliquée. Un entraxe entre la première et la deuxième poulie (14A, 14B) peut être ajusté de manière sélective pour contrôler la tension de la corde (12).
