Abstract
(DE) Die Erfindung betrifft ein System zur Erfassung von EEG-Signalen an einem Lebewesen, wobei das System mehrere EEG-Elektroden zur Aufnahme elektrischer Signale am Lebewesen und wenigstens eine mit den EEG-Elektroden verbundene Auswerteeinrichtung aufweist, wobei Auswerteeinrichtung dazu eingerichtet ist, wenigstens die folgenden Schritte durchzuführen: a) Aufnehmen von EEG-Signalen von den EEG-Elektroden, b) Berechnen wenigstens von bipolaren und quadrupolaren Feldanteilen des elektrischen Feldes im Lebewesen, das ursächlich für die EEG-Signale ist, aus den EEG-Signalen, c) Bestimmen wenigstens einer physiologischen Kenngröße des Lebewesens aus den berechneten zumindest bipolaren und quadrupolaren Feldanteilen.
(EN) The invention relates to a system for sensing EEG signals on a living being, the system having multiple EEG electrodes for picking up electrical signals on the living being and at least one evaluation device connected to the EEG electrodes, the evaluation device being designed to carry out at least the following steps: a) receiving EEG signals from the EEG electrodes; b) calculating from the EEG signals at least bipolar and quadrupolar field components of the electric field in the living being causing the EEG signals; c) determining at least one physiological characteristic of the living being from the calculated at least bipolar and quadrupolar field components.
(FR) L'invention porte sur un système de détection de signaux d'EEG sur un être vivant, le système comportant de multiples électrodes d'EEG pour capter des signaux électriques sur l'être vivant et au moins un dispositif d'évaluation connecté aux électrodes d'EEG, le dispositif d'évaluation étant conçu pour exécuter au moins les étapes suivantes consistant à : a) recevoir des signaux d'EEG en provenance des électrodes d'EEG ; b) calculer à partir des signaux d'EEG au moins des composantes de champ bipolaire et quadripolaire du champ électrique dans l'être vivant provoquant les signaux d'EEG ; c) déterminer au moins une caractéristique physiologique de l'être vivant à partir desdites composantes de champ bipolaire et quadripolaire calculées.
