Abstract

A system for actuating a spray pump assembly comprises a reference platform, a motor, a drive transmission, a spray pump holder, a force coupler, a force transducer, and a system controller. The motor receives a power and control input, and produces a rotary drive output. The drive transmission receives the rotary drive output and produces a linear drive output. The spray pump holder secures the spray pump assembly. The force coupler couples the linear drive output to the spray pump, and applies a force to the spray pump. The force transducer produces a force signal proportional to the force applied to the spray pump. The system controller receives a set of test inputs and provides the control input to the motor as a function of the set of test inputs. The system actuates the spray pump mechanism according to an actuation profile defined by the set of test inputs.

Claims

1. A spray pump holder for securing a spray pump assembly having a reservoir component and a pump/nozzle component, comprising:

(i) a clamp having an aperture disposed about a central axis, and a plurality of fingers disposed about the perimeter of the aperture and extending out from the clamp parallel to the central axis;

(ii) a compression member removably attached to the clamp;

wherein the pump/nozzle component is inserted into the aperture along the central axis, and the compression member, when attached to the clamp, compresses the plurality of fingers against the pump/nozzle component so as to secure the pump/nozzle component to the clamp.

2. A spray pump holder according to claim 1, in which the clamp consists of a low friction material.

3. A spray pump holder according to claim 2, in which the low friction material is Teflon.

4. A spray pump holder according to claim 1, in which the compression member is constructed and arranged to variably compress the plurality of fingers against the pump/nozzle component.

5. A spray pump holder according to claim 1, in which the clamp and the compression member include mating threads, the compression member screws into the clamp and drives the fingers toward the central axis.

6. A spray pump holder according to claim 1, in which the compression member consists of anodized aluminum.

7. A spray pump holder according to claim 1, further including an annular insert disposed about the central axis, between the fingers and the central axis, the pump/nozzle component inserted through the annular insert and the fingers compress the annular insert against the pump/nozzle component.

8. A spray pump holder according to claim 1, in which each of the fingers comprises a triangular cross section in a plane perpendicular to the central axis.

9. A spray pump holder according to claim 1, in which the clamp comprises by a substantially square body disposed within a plane perpendicular to the central axis.

10. A spray pump holder according to claim 9, in which opposite sides of the square body slide into corresponding grooves in a reference platform.

11. A spray pump holder for securing a spray pump assembly having a reservoir component and a pump/nozzle component, comprising:

(i) a bracket for supporting the spray pump assembly, and

(ii) at least one securing strap for removably securing the spray pump assembly against the bracket.

12. A spray pump holder according to claim 11, in which the bracket includes a first cradle member having a first engaging surface for retaining a first surface of the reservoir component, and a second cradle member having a second engaging surface for retaining a second surface of the reservoir component.

13. A spray pump holder according to claim 12, in which the first engaging surface is substantially orthogonal to the second engaging surface.

14. A spray pump holder according to claim 12, in which the first engaging surface includes a V-shaped surface, the first engaging surface contacting a reservoir component having an arcuate exterior surface at two locations.

15. A spray pump holder according to claim 12, in which the second engaging surface includes a V-shaped surface, the second engaging surface contacting a reservoir component having an arcuate exterior surface at two locations.

16. A spray pump holder according to claim 12, in which the bracket further includes an aperture, disposed between the first cradle member and the second cradle member, for accommodating a heel portion of the spray pump assembly.

17. A spray pump holder according to claim 11, further including a first securing strap and a second securing strap, the first securing strap securing the spray pump assembly against the first cradle member, and the second securing strap securing the heel portion of the spray pump assembly into the aperture and against the second cradle member.

18. A spray pump holder according to claim 11, in which a first end of the at least one securing strap is fixedly attached to a first anchor on the bracket, and a second end of the at least one securing strap is removably attached to a second anchor on the bracket.

19. A spray pump holder according to claim 18, in which the second end of the at least one securing strap loops around the second anchor removably attaches to a distal portion of the securing strap.

20. A spray pump holder for securing a spray pump assembly, comprising:

(i) a base including a body member, and a housing member having a stop tab; and

(ii) a clamping assembly including a first lever and a second lever pivotally attached at a pivot point about a pivot axle, and a spring attached to the first lever and the second lever so as to force together a first end of the first lever and a first end of the second lever;

wherein the stop tab provides a platform against which a pump/nozzle component of a spray pump assembly presses, and the pump/nozzle component is secured between the first end of the first lever and a first end of the second lever.

21. A spray pump holder according to claim 20, in which the body member is characterized by a square body, and opposite sides of the square body slide into corresponding grooves in a reference platform.
