(under the class definition) Subject matter comprising data bearing means containing information in symbolic form and detection means to sense invisible radiation from or modified by the form to produce an electric signal corresponding to the form, and methods of using such means.
(1) Note. The symbolic forms of this subclass type represent information by convention only. Thus, for example, a photograph of an object is not a symbolic form of the object because it does not represent the object by convention.
(2) Note. Included are fluorescent, radioactive and radiation controlling markings.
