Classification: CPC G  H | IPC G

Claim 7:
8. A method comprising:
outputting a stream of droplets from a droplet generator;
irradiating, with a laser, the droplets at an irradiation location between the droplet generator and a droplet receiver;
generating a net charge in the droplets downstream from the irradiation location;
receiving the droplets in the droplet receiver downstream from the irradiation location;
generating, with a droplet sensor positioned within the droplet receiver, sensor signals indicative of a speed of the droplets within the droplet receiver;
reducing a speed of the droplets within the droplet receiver by generating an electric field within the droplet receiver; and
adjusting the electric field in response to the sensor signals.
