Publication number: 20050019900Abstract: A method of controlling the presence or absence of a volume of liquid in a container or of controlling the filling of a container with a liquid volume. A channel passes through the container and channel opens into a shaft which collects all or part of the liquid. The channel(s) and shaft(s) form a fluidic network. Implementation of the method includes: detecting the capacity, or another related parameter, such as the relative permittivity of the air present in the container, the oscillation frequency or the voltage, at each shaft before the liquid is injected; detecting the capacity, or another related parameter, at each shaft after the liquid has been injected; determining the capacitive variation, or a variation in a related parameter, at each shaft; and deducing the quantity of liquid present at each reaction shaft. The invention is particularly suitable for use in the field of diagnosis.Type: ApplicationFiled: December 18, 2002Publication date: January 27, 2005Inventors: Patrick Broyer, Pierre Imbaud
