Abstract: A driver circuit for driving, for example, ultrasonic transducers in medical equipment, such as ultrasound scanning equipment. The driver circuit includes first inputs receptive of a pulsed signal, second inputs receptive of an analog signal, an output for applying a pulsed drive signal or an analog drive signal to a load. A pair of output transistors of complementary polarities are positioned with their current paths in series between opposing supply lines with a connection point intermediate between the transistors of the pair of transistors. The connection point between output transistors is coupled to the output of the circuit. The control terminals of the output transistors, which are coupled together, may be coupled to the first inputs with the driver functioning as a pulser, or else coupled to the second inputs with the driver functioning as a linear driver.

Abstract: Various arrangements for determining an atomization element of a nebulizer is dry are presented. The vibratable element of the nebulizer may be energized with an electrical signal that sweeps from a first frequency to a second frequency. While energizing the vibratable element of the nebulizer with the electrical signal that sweeps from the first frequency to the second frequency, a sequence of impedance values of the vibratable element of the nebulizer may be measured. The sequence of impedance values of the vibratable element of the nebulizer may be analyzed to determine if the atomization element of the nebulizer is wet or dry.

Abstract: The invention provides an ultrasonic nebulizer comprising a circuit unit, a nebulization module, and a frequency sweeping unit. The invention utilizes the technique of maintaining constant electric power in the nebulization module of the ultrasonic nebulizer by automatic compensation of electric power consumption and/or current consumption. Using such a technique, the invention allows a fixed current consumption and electric power consumption of a nebulization module of an ultrasonic nebulizer by auto compensation, thereby improving nebulization performance.

Abstract: The present invention relates to an apparatus and process for producing a thin organic film on a substrate using an ultrasonic nozzle to produce a cloud of micro-droplets in a vacuum chamber. The micro-droplets move turbulently within the vacuum chamber, isotropically impacting and adhering to the surface of the substrate. The resulting product has a smooth, continuous, conformal, and uniform organic thin film, when the critical process parameters of micro-droplet size, shot size, vacuum chamber pressure, and timing are well-controlled, and defects such as “orange peel” effect and webbing are avoided. The apparatus includes an improved ultrasonic nozzle assembly that comprises vacuum sealing and a separate, independent passageway for introducing a directed purging gas.
