The disclosure relates to a system having an image capturing device and an object-oriented motion detector with a motion analysis algorithm that detects motion of a subject and signals the image capturing device responsive to the motion of the subject. Additional dimensional standards measure the number of turns of the input shaft and are arranged in parallel to each other. From a bench-top small generator, producing about 1 lb of CO2 per day to a large-scale generator producing 1 ton of CO2 per day, the process is essentially identical.
