Abstract

A fluid mover and method of operating includes a pair of spaced electrodes, a power supply electrically coupled to the pair of spaced electrodes, and at least one environment sensor. The fluid mover also includes a controller configured to controllably operate at least one of the power supply or the pair of spaced electrodes.

First claim

What is claimed is:

1. A fluid mover, comprising:
a pair of spaced electrodes;
a power supply electrically coupled to the pair of spaced electrodes;
at least one environment sensor configured to output a signal indicative of an environmental parameter; and
a controller electrically coupled to the at least one environment sensor, the power supply, and the pair of spaced electrodes, with the controller configured to:
determine a breakdown voltage based on the environmental parameter wherein electrical arcing is enabled between the pair of spaced electrodes;
determine an operating parameter of the fluid mover based on the breakdown voltage; and
controllably operate at least one of the power supply or at least one electrode in the pair of spaced electrodes based on the operating parameter.

2. The fluid mover of claim 1 wherein the operating parameter comprises an operating voltage across the pair of spaced electrodes and the controller controllably operates the power supply to form the operating voltage.

3. The fluid mover of claim 1 wherein the operating parameter comprises an operating voltage across the pair of spaced electrodes, and wherein the controller being configured to controllably operate the pair of spaced electrodes includes modifying a physical characteristic of the pair of spaced electrodes to form the operating voltage.

4. The fluid mover of claim 3 wherein the modifying the physical characteristic comprises modifying a spacing distance defined between the pair of spaced electrodes.

5. The fluid mover of claim 4 , further comprising an actuator electrically coupled to the controller and the pair of spaced electrodes and configured to exert a force on the at least one electrode to modify the spacing distance.

6. The fluid mover of claim 1 wherein the controller is configured to controllably operate the power supply and to modify a spacing distance between the pair of spaced electrodes based on the operating parameter.

7. The fluid mover of claim 1 wherein the at least one environment sensor comprises an air pressure sensor for determining one of an air pressure within the fluid mover or an air pressure external to the fluid mover.

8. The fluid mover of claim 1 , further comprising a housing and wherein the at least one environment sensor is located within the housing.

9. The fluid mover of claim 8 wherein the at least one environment sensor comprises a first environment sensor located within the housing and a second environment sensor located external to the housing.

10. A method of operating a fluid mover, the method comprising:
sensing, via at least one environment sensor, at least one environmental parameter;
modifying a physical characteristic of a pair of spaced electrodes in the fluid mover; and
forming an operating voltage across the pair of spaced electrodes based on the at least one environmental parameter to cause a fluid flow between the pair of spaced electrodes.

11. The method of claim 10 wherein the forming the operating voltage further comprises operating a power supply conductively connected to the pair of spaced electrodes.

12. The method of claim 11 wherein operating the power supply further comprises modifying a supply of power to the pair of spaced electrodes.

13. The method of claim 10 , further comprising determining a breakdown voltage based on the at least one environmental parameter wherein electrical arcing is enabled between the pair of spaced electrodes.

14. The method of claim 10 , further comprising repeatedly sensing the at least one environmental parameter and repeatedly forming the operating voltage.

15. The method of claim 14 , further comprising comparing a present operating voltage to a previous operating voltage and determining an updated operating voltage based on the comparing.

16. The method of claim 10 , wherein the sensing further comprising sensing the at least one environment parameter via a sensor located within a housing of the fluid mover.

17. A fluid mover, comprising:
a pair of spaced electrodes;
a power supply electrically coupled to the pair of spaced electrodes;
at least one environment sensor configured to output a signal indicative of an environmental parameter proximate to the pair of spaced electrodes, the environmental parameter corresponding to altitude, humidity level, or fluid pressure; and
a controller electrically coupled to the at least one environment sensor, the power supply, and the pair of spaced electrodes, with the controller configured to:
determine an operating parameter of the fluid mover based on the signal indicative of the environmental parameter; and
controllably operate at least one of the power supply or at least one electrode in the pair of spaced electrodes based on the operating parameter.

18. The fluid mover of claim 17 , further comprising a housing defining an interior, wherein the pair of spaced electrodes and the at least one environment sensor are located within the interior.

19. The fluid mover of claim 17 , wherein the environmental parameter corresponds to fluid pressure proximate to the pair of spaced electrodes.

20. The fluid mover of claim 19 , wherein the controller is configured to controllably operate the power supply based on the fluid pressure.
