<p>To ejecting a droplet from a reservoir, the reservoir holding a fluid is moved with respect to an acoustic ejector. As the reservoir and ejector move closer together, the acoustic ejector sends one or more interrogation pulses towards the reservoir. Based on the interrogation pulses, the system determines when the movement of the reservoir has placed a free surface of the fluid in a position where a droplet can be ejected.</p> |
