1. An aerosolization device comprising:
- a liquid supply system that is adapted to hold a supply of liquid;
an aerosol generator configured to aerosolize liquid supplied from the liquid supply system;
a sensor that is configured to sense an amount of unaerosolized liquid that has been previously supplied to the aerosol generator; and
a controller to control operation of the liquid supply system based on information received from the sensor.

Abstract
A method for controlling the supply of liquid to an aerosol generator comprises operating a liquid supply system to supply a liquid to a vibratable aperture plate of an aerosol generator which senses an amount of liquid adhering to the vibratable aperture plate, and controls operation of the liquid supply system to adjust the amount of liquid adhering to the vibratable aperture plate.

21. An aerosolization device comprising:
-
a liquid supply system that is adapted to hold a supply of liquid; an aerosol generator comprising an element having a plurality of apertures and an electrical transducer disposed to vibrate the element when energized; a sensor configured to sense an electrical characteristic of the electrical transducer that is dependent upon an amount of unaerosolized liquid adhering to the element; and a controller to control operation of the liquid supply system based on the electrical characteristic sensed by the sensor, whereby the amount of unaerosolized liquid adhering to the element is maintained within a certain range during aerosolization. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
