DISPOSITIF AUXILIAIRE ALIMENTÉ POUR MOUVEMENT DE MEMBRE MULTIFONCTIONNEL, NOTAMMENT PROTHÈSE ET ORTHÈSE D'ASSISTANCE AU MOUVEMENT, AVEC DES RÉGIMES D'ESTIMATION COMBINÉE
A method of operating a multi-functional limb movement auxiliary device comprising a plurality of actuators configured to move, upon activation, limb movement auxiliary device members in at least two independent degrees of freedom, a bio-signal sensing unit (16) that is configured to acquire bio-signals indicative of motor activity, a control unit (24) configured to receive and evaluate the acquired bio-signals, the method comprising steps of- acquiring (44) bio-signals from the user of the limb movement auxiliary device,- applying (48) a novelty detection method (ND) for comparing digitally converted, acquired bio-signals with calibration bio-signals, and, based on a result of the comparison, for assigning (50) a similarity measure to the acquired, digitally converted bio-signals,- applying (54) at least one sequential estimator (SEQ-E) to the acquired, digitally converted bio-signals, if the assigned similarity measure is equal to or larger than a pre-determined threshold value,- applying (56) at least one simultaneous estimator (SIM-E) to the acquired, digitally converted bio-signals, if the assigned similarity measure is less than the pre-determined threshold value, and- activating (58) at least one actuator out of the plurality of actuators, based on a result of applying one of the estimators (SIM-E, SEQ-E) to the acquired, digitally converted biosignals； anda multi-functional limb movement auxiliary device including a control unit (24) configured for carrying out such method.
