Patent ID: 8880362

Claim:
A method for monitoring a paint line being applied to a surface by a paint application vehicle, comprising: generating a first electronic signal from a line pressure sensor monitoring line pressure of pavement marking material in a supply line between a pavement marking material pump and a paint gun; generating a second electronic signal representative of a speed of the vehicle over a surface; receiving the first, and second electronic signals at a processor, wherein the processor is operative to: calculate a paint thickness applied to the surface based on said first electronic signal representative of said line pressure and said second electronic signal representative of said speed of the vehicle; automatically recalculate the paint thickness based on additional electronic signals from said line pressure sensor; and upon identifying a change in line pressure from the line pressure sensor, generate an output operative to alter a speed of said pavement marking material pump supplying said pavement marking material to said paint gun to maintain said paint thickness within a desired thickness range.
