1. A method for controlling a base device configured to act upon a target substrate, the method comprising:
detecting energy from the test substrate via a sensor;
generating a profile signal of the test substrate based on the energy detected by the sensor;
comparing the profile signal of the test substrate to a profile signal of a target substrate; and
actuating the base device only when the profile signal of the test substrate is determined to correspond to the profile signal of the target substrate.
