Hand Held Micro-fluid Ejection Devices Configured to Eject Fluid without Referential Position Information and Method of Ejecting Fluid |
摘要 |
A hand-held micro-fluid ejection device for manually ejecting fluid droplets onto a substrate during relative translational motion between the ejection device and a target area on the substrate. The ejection device includes a frequency generator to set a designated frequency signal for fluid droplet ejection by the device. The frequency generator is configured to operate open-loop with respect to the relative translational motion between the ejection device and the target area. An electronic processor uses the designated frequency signal to drive a micro-fluid ejection head that produces a predetermine droplet pattern. In some embodiments a manual tuner is provided to adjust the designated frequency. In some embodiments the designated frequency signal includes more than one component to control different elements of fluid being ejected.
