That's a possibility, Rover.
Perhaps if we knew a bit more about what the machine did we could give a definitive answer.
In drug research laboratories, the integrating machine keeps track of the entire amount of one chemical substance that is introduced (slowly) into another. It keeps track of the quantity and the time the substance was introduced into the mass.
Because Csika used the word "machine", I was drawn to my definition. However, it may very well be the electronic device your link describes. It may also be something completely different.
Csika, give us a hand here.
