Abstract

A system may include an electrostatic spray tool having a turbine generator configured to generate electrical power to electrostatically charge a spray. The spray tool also may include a controller configured to monitor the electrical power from the turbine generator and to instruct a gas supply to vary a gas flow to the turbine generator based on feedback received from one or more sensors.

First claim

The invention claimed is:

1. A system, comprising:
an electrostatic spray tool, comprising:
a turbine generator configured to generate electrical power to electrostatically charge a spray; and
a controller configured to monitor the electrical power from the turbine generator and to instruct a gas supply to vary a gas flow to the turbine generator based on feedback received from one or more sensors.

2. The system of claim 1 , comprising a power module having the turbine generator disposed within a user wearable structure.

3. The system of claim 2 , wherein the power module comprises the controller and a user interface.

4. The system of claim 2 , wherein the power module comprises a power storage unit.

5. The system of claim 4 , comprising a charging unit having an inductive charging assembly configured to wirelessly charge the power storage unit.

6. The system of claim 4 , wherein the turbine generator is configured to selectively operate as a motor driven fan using power stored in the power storage unit.

7. The system of claim 2 , wherein the power module is removably coupled to the electrostatic spray tool.

8. The system of claim 7 , wherein the power module comprises a handle mount configured to removably mount the power module to a handle of the electrostatic spray tool.

9. The system of claim 7 , wherein the power module comprises a barrel mount configured to removably mount the power module to a barrel of the electrostatic spray tool.

10. The system of claim 1 , wherein the feedback comprises a current, a voltage, a droplet size of spray, a transfer efficiency of spray, a distance to target object, or one or more environmental conditions.

11. The system of claim 1 , wherein the controller is configured to selectively operate the electrostatic spray tool in a current control mode or a voltage control mode.

12. The system of claim 1 , wherein the controller is configured to selectively operate the electrostatic spray tool in a liquid spray mode or a powder spray mode.

13. The system of claim 1 , wherein the electrostatic spray tool comprises a cascade voltage multiplier configured to receive the electrical power from the turbine generator to electrostatically charge the spray.

14. The system of claim 1 , wherein the electrostatic spray tool comprises an inductive charging system configured to wirelessly transmit the electrical power from the turbine generator to at least one electrical component of the electrostatic spray tool.

15. A system, comprising:
a spray tool support module configured to support a spray tool, wherein the spray tool support module comprises:
a power supply comprising a plurality of blades coupled to a rotor-stator assembly having a plurality of windings; and
a controller coupled to the power supply, wherein the controller is configured to selectively operate the power supply in a turbine generator mode or a motor driven fan mode, a current control mode or a voltage control mode, a liquid spray mode or a powder spray mode, a sensor feedback control mode or a manual control mode, or any combination thereof.

16. The system of claim 15 , wherein the controller is configured to selectively operate the power supply in the current control mode or the voltage control mode.

17. The system of claim 15 , wherein the controller is configured to selectively operate the power supply in the liquid spray mode or the powder spray mode.

18. The system of claim 15 , wherein the controller is configured to selectively operate the power supply in the sensor feedback control mode or the manual control mode.

19. The system of claim 15 , wherein the controller is configured to selectively operate the power supply in the turbine generator mode or the motor driven fan mode.

20. The system of claim 19 , wherein the rotor-stator assembly comprises a motor generator having the plurality of windings.

21. The system of claim 19 , wherein the spray tool support module comprises a power storage unit.

22. The system of claim 15 , wherein the spray tool support module comprises a user interface.

23. The system of claim 15 , wherein the spray tool support module comprises a fluid output and a power output configured to couple to the spray tool.

24. The system of claim 15 , wherein the controller is configured to control an electrostatic spray process of the spray tool.

25. The system of claim 15 , wherein the controller is configured to monitor an electrical power generated by spray tool support module and instruct a fluid supply to vary a fluid flow to the spray tool support module based on feedback received from one or more sensors.

26. The system of claim 15 , comprising the spray tool, wherein the spray tool comprises a powder spray tool.
