Abstract
(EN)
The present invention relates to a method for eliminating interference due to artefacts of a person's movement or having a non-biological origin such as various electrical interference or noises generated by appliances. To this end, pulses of an electrical current are recorded wherein said pulses are function of a phase component of the derma electrical activity. The incoming time of a first time-derivative pulse is then determined using the logarithm of the numerical value of a current that is recorded at the moment when the value of a second derivative exceeds a threshold value. The form of the pulse is further analysed and, when parameters of this form correspond to given criteria, said pulse is related to the phase component pulses. When the parameters of this form do not correspond to the given criteria, the pulse is related to the artefacts. The analysis of pulse form may be performed using instruments or programmes.

Cette invention concerne un procédé permettant d'éliminer les perturbations qui sont fonction d'artefacts du mouvement d'une personne, ou qui ont des causes non biologiques telles que diverses perturbations électriques ou bruits émis par des appareils. A cette fin, on enregistre des impulsions d'un courant électrique qui sont fonction d'une composante de phase de l'activité électrique du derme. On définit ensuite le temps d'arrivée de l'impulsion d'une première dérivée temporelle, ceci à partir d'un logarithme de la valeur numérique du courant enregistré au moment où la valeur d'une seconde dérivée dépasse une valeur seuil. On analyse ensuite la forme de l'impulsion puis, lorsque les paramètres de cette forme répondent à des critères donnés, on rapporte cette impulsion aux impulsions de la composante de phase. Dans le cas contraire, l'impulsion est rapportée aux artefacts. L'analyse de la forme des impulsions peut se faire à l'aide d'instruments ou de programmes.
