Publication number: 20090251749Abstract: A holographic overlay is provided, including: a polycarbonate substrate having a first side and a second side, a diffractive structure cast upon the first side of the polycarbonate substrate, and a reflection-enhancing coating on at least a part of the diffractive structure; wherein the second side of the polycarbonate substrate provides a substantially flat external surface of the overlay capable of fusing to a conforming surface in the presence of heat and pressure without an adhesive. Optionally, the overlay is laser-engraved so as to form ablated voids in the metal coating and carbonize the laser engravable polycarbonate under the ablated voids. According to another aspect of the invention, a metal coating on a hologram is made substantially transparent using a laser to form a transparent portion of a hologram. Optionally, it is done after applying the hologram to an object such as a card, a document, etc., in register with underlying information to ensure its visibility and continuity of the hologram.Type: ApplicationFiled: April 8, 2009Publication date: October 8, 2009Applicant: JDS Uniphase CorporationInventors: Lily O'BOYLE, Garth ZAMBORY, Salvatore F. D'AMATO

Patent number: 6440277Abstract: An improved method and apparatus for applying discrete area holograms or other optical devices directly onto documents or other substrates in a continuous process analogous to the operation of a printing press. The continuous process is carried out in a vacuum chamber in which at least two process steps are performed in sequence: the formation of a micro-grooved discrete resin area and a localized coating of it with a reflective or refractive material layer. The formation of the micro-grooved resin area can be accomplished by electron beam curing of the resin. The localized coating of the micro-grooved resin can be done by sputtering. One or more other steps, including pre-coating, post-coating and partial removal of the reflective or refractive layer, may also be carried out as part of the continuous process within the vacuum chamber.Type: GrantFiled: March 9, 2000Date of Patent: August 27, 2002Inventor: Salvatore F. D'Amato

Patent number: 5393099Abstract: The present invention pertains to a method of producing an anti-counterfeiting document or currency which acts and feels like existing paper currencies. The method of the present invention laminates two sheets of currency paper on each side of a thin durable substrate film, thereby forming a durable document which maintains a paper-like feel. The currency of the present invention exhibits unique and powerful anti-counterfeiting features compared to those presently available. The currency of the instant invention also lasts significantly longer than conventional "paper" money.Type: GrantFiled: May 21, 1993Date of Patent: February 28, 1995Assignee: American Bank Note Holographics, Inc.Inventor: Salvatore F.

Patent number: 5116548Abstract: A method and system for replicating microstructures surface relief patterns, such as diffraction patterns including holograms, by casting. A liquid casting resin is held between a surface relief master of the microstructure to be replicated and a substrate while the resin is hardened by actinic radiation curing. Application of resin to edges and discontinuities of the master is avoided in order to reduce undesirable build-up of resin on these areas of the master. The hardened resin surface relief replica may optionally be coated with a discontinuous graphical pattern of a clear or colored paint that eliminates the effect of the surface relief pattern in the regions so coated.Type: GrantFiled: June 22, 1990Date of Patent: May 26, 1992Assignee: American Bank Note Holographics, Inc.Inventors: Donald W. Mallik, Salvatore F. D'Amato

Patent number: 5071597Abstract: A technique for forming a mold to replicate large numbers of plastic articles, such as by injection or blow molding, wherein the mold contains a hologram or other microstructure for transfer to an outside surface of the molded article. The mold is made by electrodepositing a metal on a model of the article to be molded. Before this deposition, the hologram or other microstructure is formed on a surface area of the model by any one of several techniques. The result is a unitary mold piece in the shape of the article and having the hologram or other microstructure integrally formed on its inside surface.Type: GrantFiled: September 27, 1989Date of Patent: December 10, 1991Assignee: American Bank Note Holographics, Inc.Inventors: Salvatore F.

Patent number: 4900111Abstract: Embossed holograms or diffraction patterns are formed on hard, unembossible metal substrates such as steel sheet metal. The hard metal substrate has a soft embossible metal layer such as tin formed on it, and holograms are embossed thereon by means of a surface relief, metal master. The soft metal layer must be sufficiently thick to accommodate the deepest surface relief pattern. For tinplate, the embossing can be preformed at room temperature. Among other things, the process produces tinplates and tin cans with embossed holograms.Type: GrantFiled: February 15, 1989Date of Patent: February 13, 1990Assignee: American Bank Note Holographics, Inc.Inventors: Salvatore F.

Patent number: 4455039Abstract: Documents are encoded with at least one thin, transparent coating, normally invisible, but having a readily detectable physical characteristic such as, electrical conductivity, electrical impedance, electrical capacitance, electroluminescence. Each document consists of a substrate on which is applied (1) at least one of the thin coatings, and (2) conventional printing, preferably intaglio. The thin coating may be applied before or after the printing. The coating includes particles driven into the surface to a substantial depth. The uncoated substrate is free of the detectable physical characteristic. The coating is confined to a limited area of the substrate surface and itself constitutes a code or is laid down in a pattern for identification. A second coating can be applied so that all areas of the surface have the same appearance to mask visual detection of the first coating.Type: GrantFiled: June 24, 1982Date of Patent: June 19, 1984Assignee: Coulter Systems CorporationInventors: Edward H.

Patent number: 4313087Abstract: This apparatus tests the genuineness of a document carrying anticounterfeit protection in the form of a usually invisible, electrically conductive coating on at least part of a surface. The apparatus may be arranged to respond to the presence of a coating anywhere on the surface, or it may be arranged to respond only to a coating of specific contour, in a specific location. The apparatus shown comprises an array of contacts and means for supporting a document to be tested in conductive engagement with said contacts. Certain ones of the contacts engage the conductive layer, and are connected in an electric circuit which is completed through the conductive layer. Completion of the circuit is required to produce an indication that the document is genuine. The conductance of the conductive layer must be within a predetermined range in order to produce a signal indicating that the document is genuine.Type: GrantFiled: February 7, 1980Date of Patent: January 26, 1982Inventors: Edward H. Weitzen, Salvatore F. D'Amato

Patent number: 3982453Abstract: This method and apparatus starts with a lot of distinctively numbered documents consisting of a plurality of stacks of sheets, each sheet bearing multiple reproductions of the document. The documents in corresponding locations of successive sheets in the stack are in consecutive numerical order. In each sheet, the documents are arranged by rows and columns in an arbitrary, nonconsecutive numerical order in which successive members of the order bear numbers separated by a fixed difference. The method involves separating the stacks of documents into a plurality of piles, each pile having its documents in consecutive numerical order, but with the corresponding documents in successive piles separated by said fixed difference. The piles from successive stacks are deposited on successive ones of a plurality of tributary conveyors, all of which deliver their piles to a main conveyor.Type: GrantFiled: July 15, 1974Date of Patent: September 28, 1976Assignee: American Bank Note CompanyInventors: Salvatore F. D'Amato, Francis T. Moss
