Patent ID: 6942736

Claim:
A system for the user directed manual application of a fluid material in a linear pattern to a surface from a container holding the fluid comprising: the container holding a fluid, the container having an application end from which fluid is applied to the surface at a volume flow rate that provides a volume/linear distance of the linear pattern, a controllable pressure system that causes pressure in the container, wherein application of higher pressure causes increased flow of fluid from the container and reduction of pressure causes reduced flow of fluid from the container, a speed indicator that provides a signal of the relative speed between the application end and the surface, a microprocessor that reads the signal and determines if the controllable pressure is at a predetermined target level with respect to the relative speed, the microprocessor adjusting the controllable pressure system to attempt to maintain a standard volume of liquid per linear distance of the linear pattern; wherein the container holding a fluid is held by hand by a user.
