Claim Text:
1. A precision pumping system for delivering a spray of skin treatment solution, comprising: at least one nozzle configured to emit a spray of a skin treatment solution; a positive displacement pump in fluid communication with the at least one spray nozzle, the positive displacement pump comprising a displaceable member, displacement of the displaceable member corresponding to a pumping cycle of the positive displacement pump; a controller in communication with the positive displacement pump, the controller being operable to apply a predetermined actuation parameter to direct an expected displacement of the displaceable member and being further operable to receive an indication of an actual position of the displaceable member; a flag coupled to the displaceable member; and a position sensor operable to detect the flag; wherein the controller is further operable to compare the predetermined actuation parameter associated with the expected displacement of the displaceable member to a measured actuation parameter associated with the actual displacement of the displaceable member.
