US Patent 9616447 Material dispensing system and methods

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.
