Abstract

A method and apparatus for applying a fluid onto a number of surfaces. The apparatus comprises a structure, an applicator associated with the structure, a first control device associated with the structure, and a second control device associated with the structure. Applying a first force to the first control device causes the applicator to move relative to a center axis of the applicator. Applying a second force to the second control device causes the fluid to be delivered from a fluid dispensing system to the applicator.

First claim

What is claimed is:

1. An apparatus comprising:
a structure;
an applicator associated with the structure;
a first control device associated with the structure, wherein applying a first force to the first control device causes the applicator to move relative to a center axis of the applicator;
an actuation device configured to create reciprocating motion in response to the first force being applied to the first control device; and
a second control device associated with the structure, wherein applying a second force to the second control device causes a fluid to be delivered from a fluid dispensing system to the applicator.

2. The apparatus of claim 1 further comprising:
a pulse generator configured to receive air and send a number of air pulses into the actuation device to create the reciprocating motion in response to the first force being applied to the first control device.

3. The apparatus of claim 2 , wherein the actuation device comprises:
a piston configured to be pressurized by an air pulse in the number of air pulses such that the piston moves in a first linear direction; and
a biasing element configured to move the piston in a second linear direction opposite the first linear direction in response to depressurization of the piston.

4. The apparatus of claim 3 , wherein movement of the piston in the first linear direction causes movement of the applicator in the first linear direction and wherein movement of the piston in the second linear direction causes movement of the applicator in the second linear direction.

5. The apparatus of claim 4 , wherein the actuation device further comprises:
a pulley associated with the piston and the biasing element by a cable and associated with the applicator, wherein the pulley causes the applicator to rotate in a first direction about the center axis through the applicator in response to the piston moving in the first linear direction and the applicator to rotate in a second direction about the center axis through the applicator in response to the piston moving in the second linear direction.

6. The apparatus of claim 1 further comprising:
the fluid dispensing system, wherein the fluid dispensing system is configured to dispense a high-viscosity fluid for delivery to the applicator.

7. The apparatus of claim 6 further comprising:
a valve configured to control a flow of the fluid from the fluid dispensing system to the applicator, wherein applying the second force to the second control device causes the valve to allow the fluid to flow out of a nozzle of the fluid dispensing system and wherein an absence of any force being applied to the second control device prevents the fluid from flowing out of the nozzle.

8. The apparatus of claim 6 , wherein increasing a level of the second force being applied to the second control device increases a rate of flow of the fluid from the fluid dispensing system.

9. The apparatus of claim 1 further comprising:
a gimbal device configured to connect the applicator to the structure and configured to allow the applicator to have at least one rotational degree of freedom.

10. The apparatus of claim 1 , wherein the structure is configured to be held by a human operator and has a shape configured to allow an end of the structure with which the applicator is associated to reach a desired location within an area.

11. An integrated system comprising:
a brace configured to be worn around an arm of a human operator;
a fluid dispensing system associated with the brace and configured to dispense a fluid; and
a tool configured to be held by the human operator, wherein the tool comprises:
a structure having a shape configured to allow an end of the structure to reach a desired location within an area;
an applicator associated with the end of the structure;
a movement system associated with the structure and configured to move the applicator relative to a center axis of the applicator in response to a first force being applied to a first control device in the movement system; and
a delivery system associated with the structure and configured to deliver the fluid from the fluid dispensing system to the applicator in response to a second force being applied to a second control device in the delivery system.

12. The integrated system of claim 11 further comprising:
an actuation device configured to create reciprocating motion in response to the first force being applied to the first control device.

13. The integrated system of claim 12 further comprising:
a pulse generator configured to receive air and send a number of air pulses into the actuation device to create the reciprocating motion in response to the first force being applied to the first control device.

14. The integrated system of claim 13 , wherein the actuation device comprises:
a piston configured to be pressurized by an air pulse in the number of air pulses such that the piston moves in a first linear direction; and
a biasing element configured to move the piston in a second linear direction opposite the first linear direction in response to depressurization of the piston.

15. The integrated system of claim 14 , wherein movement of the piston in the first linear direction causes movement of the applicator in the first linear direction and wherein movement of the piston in the second linear direction causes movement of the applicator in the second linear direction.

16. The integrated system of claim 15 , wherein the actuation device further comprises:
a pulley associated with the piston and the biasing element by a cable and associated with the applicator, wherein the pulley causes the applicator to rotate in a first direction about the center axis through the applicator in response to the piston moving in the first linear direction and the applicator to rotate in a second direction about the center axis through the applicator in response to the piston moving in the second linear direction.

17. The integrated system of claim 11 further comprising:
the fluid dispensing system, wherein the fluid dispensing system is configured to dispense a high-viscosity fluid for delivery to the applicator.

18. The integrated system of claim 17 further comprising:
a valve configured to control a flow of the fluid from the fluid dispensing system to the applicator, wherein applying the second force to the second control device causes the valve to allow the fluid to flow out of a nozzle of the fluid dispensing system and wherein an absence of any force being applied to the second control device prevents the fluid from flowing out of the nozzle.

19. The integrated system of claim 18 , wherein increasing a level of the second force being applied to the second control device increases a rate of flow of the fluid from the fluid dispensing system.

20. An apparatus comprising:
a structure;
an applicator associated with the structure;
a first control device associated with the structure, wherein applying a first force to the first control device causes the applicator to move relative to a center axis of the applicator;
a fluid dispensing system, wherein the fluid dispensing system is configured to dispense a high-viscosity fluid for delivery to the applicator;
a second control device associated with the structure, wherein applying a second force to the second control device causes the high-viscosity fluid to be delivered from the fluid dispensing system to the applicator; and
a valve configured to control a flow of the fluid from the fluid dispensing system to the
