Optical devices comprising at least one optical layer and at least one antistatic layer disposed on at least one surface of the optical layer wherein the antistatic layer comprises the reaction product of: at least one polymerizable onium salt; and at least one polymerizable, non-onium, silicone or perfluoropolyether moiety-containing monomer, oligomer, or polymer. A diaphragm electrode is provided on the spacer. A rotation mechanism operated by lever rotates the winding pulley. Next, the system compares the received responses with a set of reference responses gathered from properly functioning sensors in a reference computer system. The data blocks are placed around the first positioning block.
