METERING SYSTEM FOR FLUID DELIVERY

ABSTRACT An apparatus comprising a variable acoustic source and a microphone, both acoustically coupled to a volume having a fluid region and an air region. The apparatus also can include a processor to determine a volume of the air region based on signals received from the microphone and the variab...

Zusammenfassung:	ABSTRACT An apparatus comprising a variable acoustic source and a microphone, both acoustically coupled to a volume having a fluid region and an air region. The apparatus also can include a processor to determine a volume of the air region based on signals received from the microphone and the variable acoustic source. A fluid valve is coupled to the processor, and is configured to allow an amount of fluid to exit the fluid region associated with the volume of the air region. An atomizer, coupled to the fluid region, is configured to aerosolize at least a portion of the fluid. Date Recue/Date Received 2020-05-08 ABRÉGÉ : Il est décrit un appareil comprenant une source acoustique variable et un microphone couplé sur le plan acoustique à un volume ayant une région de fluide et une région dair. Lappareil peut également comprendre un processeur servant à déterminer un volume de la région dair en fonction de signaux reçus provenant du microphone et de la source acoustique variable. La configuration dun robinet de fluide couplé au processeur fait en sorte quil permette à un montant de fluide de sécouler de la région de fluide associé au volume de la région dair. La configuration dun pulvérisateur couplé à la région de fluide lui permet de réaliser laérosolisation dau moins une partie du fluide. Date reçue / Date Received 2020-05-08
