Abstract:
1. A method of controlling operation of a mechanism having a removable component removably coupled thereto, comprising the steps of: measuring electromagnetic radiation passing through a plurality of waveguides carried on a removable, replaceable component, and permitting operation of the mechanism only when measured electromagnetic radiation passing through two or more waveguides complies with one or more pre-selected output parameters, the removable component has a plurality of waveguides, and the method including measuring the electromagnetic radiation passing through two or more of said waveguides, and preventing operation of the mechanism when the measured electromagnetic radiation of a first of the waveguides does not comply with the pre-selected output parameters for the first waveguide and the measured electromagnetic radiation of a second of the waveguides does not comply with the pre-selected output parameters for the second waveguide.
