Abstract

A method and device are provided for providing sensory cues, signals, or indicators regarding the status of electrohydrodynamically spraying a material, including power-on status of an electrohydrodynamic spray device, active electrohydrodynamic spray status, and material status within the electrohydrodynamic spray device. In particular, audible, tactile, or intermittent visible signals indicate active electrohydrodynamic spraying, audible, tactile, or visible signals indicate power-on status of the electrohydrodynamic spray device, and sensory signals indicate the status of other operationally-related variables, including the rate of electrohydrodynamic spray, time increments, which may be correlated with electrohydrodynamic spray flowrates, and material supply levels.

Claims

1. A method, comprising the steps of:

electrohydrodynamically spraying a material; and

concomitantly emitting a signal selected from the group consisting of audible, tactile, variable visible, or combinations thereof.

2. The method of claim 1, wherein:

audible signal is selected from the group consisting of steady, variable, and combinations thereof; and

tactile signal is selected from the group consisting of steady, variable, and combinations thereof.

3. The method of claim 1, wherein the emitting step comprises emitting a periodic audible tone.

4. The method of claim 1, further comprising the steps of:

terminating the electrohydrodynamic spraying of the material;

concomitantly terminating emission of the signal.

5. The method of claim 1, further comprising the step of concomitantly emitting a further signal selected from the group consisting of audible, tactile, visible, or combinations thereof.

6. The method of claim 1, further comprising the steps of:

activating a device adapted to electrohydrodynamic spraying; and

concomitantly emitting a further sensory signal.

7. The method of claim 1, further comprising the step of emitting a sensory signal variable with a material spray rate.

8. The method of claim 1, further comprising the step of emitting a sensory signal in response to an amount of the material in a material supply.

15. A device adapted to enable the steps of claim 1.

9. A method, comprising the steps of:

electrohydrodynamically spraying a material;

concomitantly directing a visible signal at the spray, whereby the spray becomes illuminated.

10. A method, comprising the steps of:

directing a visible signal at a spray target; and

electrohydrodynamically spraying a material toward the target.

11. A method, comprising the steps of:

providing a device adapted to electrohydrodynamically spraying a material;

providing a material supply container adapted for the device; and

emitting a sensory signal in response to the material supply container.

12. A method, comprising the steps of:

emitting a first sensory signal;

electrohydrodynamically spraying a liquid; and

emitting a second sensory signal concomitant with the step of electrohydrodynamically spraying the liquid.

13. A method, comprising the steps of:

providing power to an electrohydrodynamic spray device and concomitantly emitting a first sensory signal; and

electrohydrodynamically spraying a material and concomitantly emitting a second sensory signal.

14. The method of claim 13, further comprising the step of emitting a third sensory signal concomitant with electrohydrodynamically spraying the liquid.

16. A device adapted to enable the steps of claim 14.

17. A device, comprising

a material supply;

an electrohydrodynamic sprayer in communication with the material;

a first switch operably connected to a first sensory signal emitter adapted to emit a signal selected from the group consisting of audible, tactile, visible, and combinations thereof; and

a second switch operably connected to the electrohydrodynamic sprayer and to a second sensory signal emitter adapted to emit a signal selected from the group consisting of audible, tactile, intermittent visible, or combinations thereof.

18. The device of claim 17, further comprising a timer operably connected to a third sensory signal emitter.

19. The device of claim 17, further comprising a liquid flow indicator operably connected to a third sensory signal emitter.

20. A device, comprising:

a material supply;

an electrohydrodynamic sprayer in communication with the material;

a first switch operably connected to a sensory signal emitter; and

a second switch operably connected to the electrohydrodynamic sprayer and to the sensory signal emitter.

21. A method, comprising:

sensing a change in state of a switch;

emitting an audible, tactile, or intermittent visible sensory signal in response to the change in state of the switch; and

effecting a change in state of a circuit within an electrohydrodynamic device.

22. The method of claim 21, further comprising the steps of:

emitting a further sensory signal in response to the change in state of the switch; and

activating an electrohydrodynamic sprayer.

23. The method of claim 21, further comprising the steps of:

sensing a change in state of a further switch;

emitting a further sensory signal in response to the change in state of the further switch; and

activating an electrohydrodynamic sprayer.
