Title (EN) METHOD FOR CONTROL OF PROSTHESES AND OTHER AID MEANS
(FR) PROCEDE PERMETTAN L'ACTIVATION D'UNE PROTHESE OU DE TOUT AUTRE APPAREIL D'ASSISTANCE
Abstract:
(EN) Described is a method for controlling prostheses and other assistive devices using tissue whose state is influenced by the central nervous system of a user. The state of the tissue is sensed, and information from this sensing is fed into a unit (9, 10) that estimates the motor intention of the user and controls the prosthesis according to this estimate. The method comprises transmission of ultrasound signals into the tissue by use of an ultrasound transducer (6) and then reception of the ultrasound signals modulated by the tissue by use of an ultrasound transducer (7). Based on these received ultrasound signals, the motor intention of the user is estimated, and based on this mentioned estimate a number of prosthesis states are controlled.
(FR) La présente invention a pour objet un procédé permettant l'activation d'une prothèse ou de tout autre dispositif d'assistance. Ce procédé, qui utilise un tissu dont l'état est influencé par le système nerveux central de l'utilisateur, consiste à sonder l'état du tissu, à communiquer les informations ainsi obtenues à une unité (9, 10) chargée d'estimer le mouvement moteur que l'utilisateur a l'intention d'effectuer, puis à activer la prothèse conformément à cette estimation. Le procédé implique la transmission de signaux à ultrasons dans le tissu à l'aide d'un transducteur à ultrasons (6), puis la réception de signaux à ultrasons modulés par le tissu à l'aide d'un ature transducteur à ultrasons (7). Sur la base des signaux à ultrasons qui ont été reçus, le mouvement moteur que l'utilisateur a l'intention d'effectuer est estimé, cette estimation servant à activer un certain nombre d'états de prothèse.
