Abstract: Method and apparatus are disclosed for the prevention of unauthorized copying of documentation on an office, or other type, copier. Unique phosphors are applied to paper. When such a paper is placed on or in a copier so prepared, the presence of the phosphor is detected and the copier is disabled. Inside the copier a laser emits a beam toward the paper. Two detectors detect, respectively, the laser light reflected from the document and the stimulated light from the phosphor coating or layer. Detection of both signals, in the proper time sequence, will cause the photocopier to cease operation prior to electrostatic or other capture of the image. Upconversion phosphors could be utilized as the phosphor coating due to their scarcity and unliklihood of use in this manner.

Abstract: A process for manufacturing secure identification cards incorporating fiber optic elements which allow the generation of a binary encoded electro-optical signal uniquely identifying that card. Blank card stock will be made from a continuous web system in which the fibers 130 are aligned and brought to an appropriate spacing by combing 134 as they are drawn into the forming machine. The formed web stock is passed through bonding rollers 138 (either thermal or pressure) and then enters a take-up accumulator 150 and then to a punch where the blank forms are punched out of the web. The accumulator stage 150 compensates for the conversion from smooth motion through aligning, mating, and bonding areas to an intermittent motion at the punch area.

Abstract: United States paper currency can be denomination sensed by a system for scanning a predetermined path along one surface and comparing the resultant scan against a standard for a particular denomination. Subsequently, it is determined whether the scanned currency is of a particular denomination or is questionable. The one surface can be an obverse surface of paper currency, the predetermined path of the obverse surface can be magnetically scanned; the scanning direction occurs along a major axis of the currency; and the scanned currency can be sorted in accordance with the determination. Various denominations can be determined at one time either in seriatim or in parallel.
