Abstract

A system and method for applying a fluid to a surface. The method includes the steps of: providing a deposition system; discharging fluid from the deposition system at a first, non-zero rate; detecting movement of the deposition system in proximity to a surface; and discharging fluid at a second rate while the deposition system is moving in proximity to the surface. The system comprises: a MEMS element coupled to a fluid reservoir and adapted to dispense fluid at a plurality of non-zero rates; at least one sensor; and a controller in communication with the MEMS element and at least one sensor and adapted to receive an output from the sensor and to alter the deposition rate of the MEMS element according to the sensor output.

First claim

What is claimed is:

1. A method for applying fluid on surfaces, comprising the steps of:
a. providing a deposition system;
b. discharging fluid from the deposition system at a first, non-zero rate;
c. detecting movement of the deposition system in proximity to a surface;
d. discharging fluid at a second rate while the deposition system is moving in proximity to the surface.

2. The method according to claim 1 further comprising steps of:
e. analyzing the surface;
f. detecting features upon the surface;
g. targeting the discharge of at least one fluid in association with a detected feature.

3. The method according to claim 1 further comprising the steps of:
h. detecting a surface proximal to the deposition system;
i. discharging fluid from the deposition system at a third, non-zero rate while proximal to the surface.

4. The method according to claim 1 wherein the fluid is selected from the group consisting of: cosmetics, polymerics, aqueous, non-aqueous, particle loaded and combination thereof.

5. The method according to claim 1 wherein the surface is selected from the group consisting of: keratinous surfaces, woven surfaces, non-woven surfaces, porous surfaces, non-porous surfaces, and combinations thereof.

6. A deposition system comprising:
a. a MEMS element coupled to at least one fluid reservoir and adapted to dispense fluid at a plurality of non-zero rates;
b.at least one sensor;
c. a controller in communication with the MEMS element and at least one sensor and adapted to receive an output from the sensor and to alter the deposition rate of the MEMS element according to the sensor output, wherein the sensor output is associated with features of the surface.

7. The deposition system according to claim 6 wherein the sensor output is associated with movement relative to the surface.

8. The deposition system according to claim 6 wherein the controller may target the dispensing of the fluid according to sensor output associated with surface features.

9. A method for applying fluid on surfaces, comprising the steps of:
a. providing a deposition system;
b. removing a cap protecting a deposition system;
c. detecting movement of the deposition system in proximity to a surface;
discharging fluid at a second rate while the deposition system is moving in proximity to the surface.
