METHOD AND APPARATUS TO PROVIDE VARIABLE DROP SIZE EJECTION BY DAMPENING PRESSURE INSIDE A PUMPING CHAMBER
摘要
<p>Described herein is a method and apparatus for driving a droplet ejection device with multi-pulse waveforms. In one embodiment, a method for driving a droplet ejection device having an actuator includes applying a multi-pulse waveform having two or more drive pulses and a cancellation pulse to the actuator. The method further includes generating a pressure response wave in a pumping chamber in response to each pulse. The method further includes causing the droplet ejection device to eject a droplet of a fluid in response to the drive pulses of the multi-pulse waveform. The method further includes canceling the pressure response waves associated with the drive pulses with the pressure response wave associated with the cancellation pulse.</p>
