Abstract
Noise potentials and radiation in an ultrasonic nebulizer are reduced by separating the oscillator and power supply and shielding the former, with one of the DC power lines to the oscillator passing through an aperture in the metal casing that shields the oscillator, while the other power supply line is connected to that casing. Oscillator control may be achieved by an unshielded variable resistor coupled by conductors of extended length to the oscillator by a filter circuit.
