Title (EN) DATA GATHERING SYSTEM
(FR) SYSTÈME DE RASSEMBLEMENT DE DONNÉES
Abstract:
(EN) A device for gathering data has first and second electrodes. The first electrode is coupled to a surface of interest, and the second electrode is coupled to "everything else" or "the air". The first electrode is shielded from the second, and from most sources of parasitic capacitance, by a shield that is driven by an active driver that drives the shield to track, and ideally to match, the instantaneous potential of the electrode. The second electrode is likewise shielded in a similar way from most sources of parasitic capacitance. These shields likewise help to limit the extent to which RFI from the device electronics couples with either of the electrodes. In this way the sensing device achieves a markedly better signal-to-noise ratio at frequency bands of interest.
(FR) Le dispositif selon l'invention servant à rassembler des données comporte des première et seconde électrodes. La première électrode est couplée à une surface intéressante et la seconde électrode est coulée à « tout le reste » ou « à l'air ». La première électrode est blindée par rapport à la seconde, et par rapport à la plupart des sources de capacité parasite, par un blindage qui est commandé par une commande active qui commande au blindage de pister, et idéalement de se mettre au niveau du potentiel instantané de l'électrode. La seconde électrode est de même blindée de manière similaire par rapport à la plupart des sources de capacité parasite. Ces blindages aident également à limiter l'étendue jusqu'à laquelle les RIF de l'électronique du dispositif sont couplées avec l'un ou l'autre électrode. De cette manière le dispositif de détection permet de réaliser un rapport signal-bruit significativement meilleur à des bandes de fréquence intéressantes.
