1. A nebulizer assembly, said assembly comprising:
- power supply means (12) for supplying power;
generating means (18) for producing fog;
control means (20) connected between said power supply means (12) and said generating means (18) for switching power to said generating means (18) to produce a predetermined volume of fog;
said control means (20) including pulsing means (22) for receiving said power and transmitting a series of pulses of power to said generating means (18) to establish an average power producing said predetermined volume of fog, and feedback means (26) for providing feedback to said pulsing means (22) of the output of said generating means (18).

Abstract
A battery powered nebulizer (10) includes a portable housing (58) containing a battery power supply (13), pump-motor combination (14), air compressor (16) and control circuitry (20). The control circuitry (20) includes a pulse width modulator (24) for switching power to the motor (14) to conserve battery charge and regulate the pump-motor combination (14) to a predetermined volume output. The nebulizer (10) includes a charger (40) for charging the battery (13) and an adapter (34) to be connected to an external battery supply. A monitor (46) monitors the charge on the battery (13) to audibly and visually indicate low battery charge.

12. A method of producing fog, the method including the steps of;
- supplying electrical current from an electrical power supply means, producing fog in response to said power, producing a series of pulses of electrical current from the power supply means for establishing an average supply of power to produce a predetermined volume of fog, and providing feedback for the production of pulses of the output of the production of fog.
