Abstract

Deux électrodes cutanées (18, 20) espacées sont attachées à un collier (10) sur des parties opposées du corps afin de détecter les battements du coeur ou d'autres signaux corporels de l'utilisateur. Les électrodes (18, 20) sont électriquement connectées par le collier lui-même (10) ou par des conducteurs (26, 48, 50, 67) incorporés dans celui-ci à des circuits agencés dans un pendentif ou module (16, 52) fixé au collier (10). Les circuits traitent les signaux corporels et peuvent également les enregistrer, afficher des informations obtenues à partir de ces signaux ou les transmettre à un élément séparé de réception, de traitement et d'affichage. Dans un mode de réalisation, le module (77) du collier comprend un microprocesseur avec mémoire vive (83) et une porte de sortie (84). Une unité réceptrice (93) est connectée à la porte de sortie (84) pour télédécharger les signaux enregistrés dans la mémoire vive (83) et les traiter dans une unité (94-98) commandé par microprocesseur qui transmet des signaux à un écran de visualisation (99). Une autre mode de réalisation comprend un émetteur de haute fréquence (76) avec une antenne (82), et une unité réceptrice (92) avec une antenne (91) susceptible d'être agencée de façon amovible dans un bracelet (54).
