Abstract: Système pour améliorer la réponse en fréquence de signaux vocaux. Une estimation de la forme spectrale vocale moyenne est calculée au cours d'une période donnée en fonction du signal vocal d'entrée. L'estimation de la forme spectrale vocale moyenne peut être calculée dans le domaine de fréquence au moyen d'un filtre à réponse impulsionnelle infinie de premier ordre ou d'intégrateurs à fuite. Par conséquent, l'estimation de la forme spectrale vocale moyenne s'adapte au fil du temps aux changements des caractéristiques acoustiques du trajet de la voix ou à tout changement du trajet audio électrique pouvant avoir des répercussions sur la réponse en fréquence du système. Un facteur de correction spectrale peut être déterminé en comparant l'estimation de la forme spectrale vocale moyenne à une forme spectrale cible souhaitée. Le facteur de correction spectrale peut être ajouté (en unités de dB) au spectre du signal vocal d'entrée afin d'améliorer ou d'ajuster le spectre du signal vocal d'entrée par rapport à la forme spectrale souhaitée et un signal vocal amélioré peut être synthétisé de nouveau à partir du spectre corrigé.

Title: Verification system for robot pose
Inventor: SHOHAM MOSHE
IPC: G05B15/00
Filed: 2005-02-03
Granted: 2014-02-11
Abstract: An apparatus and method for assuring effective backup for sensor failure in robots, by utilizing a single extra sensor attached between the end actuator and the base. The single extra sensor provides absolute back-up for any single encoder failure that may occur in the system, and statistically significant back-up for any double encoder failure. A single additional sensor effectively provides the robotic system with one redundant information input to the robot control algorithm, which can be used in order to determine whether any of the other control sensors, or even the additional sensor itself, has failed and is delivering an erroneous reading, and hence to warn the operator of the failure. A single additional sensor also provides useful warning of the simultaneous failure of two sensors, since the likelihood that two sensors fail simultaneously in a mode that makes the failures undetectable, can be regarded as statistically insignificant.
