1. An apparatus comprising:
- a variable acoustic source acoustically coupled to a volume, the volume being divided into an air region and a fluid region, the fluid region having a fluid output;
a microphone acoustically coupled to the volume;
a processor configured to receive a signal from the microphone, and further configured to determine a volume of the air region;
a fluid valve configured to allow an amount of fluid to exit the fluid region, the amount of fluid being associated with the determined volume of the air region, and wherein the processor is further configured to send a control signal to the fluid valve;
a target region coupled to the fluid valve and in selective communication with an air tank through an air valve and wherein the fluid valve and the air valve are positioned so that a substantial portion of the fluid exits the target region; and
an atomizer coupled to the fluid output, the atomizer configured to aerosolize at least a portion of the amount of fluid to exit the fluid region.

Abstract
An apparatus comprises 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.
