Title (EN) PHYSIOLOGICAL MEASUREMENT DEVICE WITH COMMON MODE INTERFERENCE SUPPRESSION
(FR) DISPOSITIF DE MESURE PHYSIOLOGIQUE À SUPPRESSION D'INTERFÉRENCE EN MODE COMMUN
Abstract:
(EN) The described embodiments relate to systems, methods, and apparatuses for reducing interference of signals transmitted by a physiological measurement device (108, 210, 312), such as an electrocardiogram device. The physiological measurement device can employ filters (308) that use coefficients to reduce time-domain differences between response signals of the physiological measurement device. The coefficients can be derived during a calibration process where each channel of the physiological measurement device is supplied a test signal (202) for identifying the channel with the slowest or most delayed response. Thereafter, when a monitor signal is compiled from response signals filtered using the coefficients, differences in timing between the response signals will not result in distortion of the monitor signal, thereby rendering the monitor signal more accurate for measurement purposes.
(FR) L'invention concerne, selon des modes de réalisation, des systèmes, des procédés et des appareils permettant de réduire l'interférence de signaux transmis par un dispositif de mesure physiologique (108, 210, 312), tel qu'un dispositif d'électrocardiogramme. Le dispositif de mesure physiologique peut utiliser des filtres (308) qui utilisent des coefficients pour réduire des différences de domaine temporel entre des signaux de réponse du dispositif de mesure physiologique. Les coefficients peuvent être déduits au cours d'un processus d'étalonnage où chaque canal du dispositif de mesure physiologique reçoit un signal de test (202) afin d'identifier le canal ayant la réponse la plus faible ou la plus retardée. Par la suite, lorsqu'un signal de surveillance est compilé à partir de signaux de réponse filtrés à l'aide des coefficients, les différences de synchronisation entre les signaux de réponse ne donneront pas de distorsion du signal de surveillance, ce qui permet de rendre le signal de surveillance plus précis à des fins de mesure.
