Title (EN) FLUID COVERAGE SENSING SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE DÉTECTION DE COUVERTURE DE FLUIDE
Abstract:
(EN) A system for applying a fluid to a substrate (1) bearing a sample for analysis (3) has an array of sensor plates (19a, 19b) positioned to sense the presence of fluid in contact with respective areas of the substrate. In a particular embodiment, fluid presence in different areas of the substrate is sensed by the effect of the fluid and its identity on the impedances of capacitors formed between sensor plates within the array. In a more particular embodiment, by polling the sensor array continually while fluid is applied to the substrate determine a coverage map, a fluid dispensing mechanism can be controlled to efficiently cover the entire substrate with fluid a minimal amount of fluid, thereby reducing waste.
(FR) L'invention concerne un système pour appliquer un fluide sur un substrat (1) portant un échantillon à analyser (3), qui a un réseau de plaques de capteur (19a, 19b) positionnées pour détecter la présence de fluide en contact avec des zones respectives du substrat. Dans un mode de réalisation particulier, la présence de fluide dans différentes zones du substrat est détectée par l'effet du fluide et son identité sur les impédances de condensateurs formées entre des plaques de capteur dans le réseau. Dans un mode de réalisation plus particulier, en interrogeant le réseau de capteurs de manière continue tandis que le fluide est appliqué sur le substrat pour déterminer une carte de couverture, un mécanisme de distribution de fluide peut être commandé pour recouvrir efficacement tout le substrat avec une quantité minimale de fluide, en réduisant ainsi les déchets.
