Abstract: An optically variable device (“OVD”) with an integral image system that includes a focusing element and an array of micro-objects which, when viewed through the focusing element, changes in appearance depending on the relative location from which the OVD is observed. A security device including the OVD and methods for creating the OVD are also disclosed.

Abstract: An optically variable magnetic stripe assembly comprises a magnetic layer (5); an optically variable effect generating layer (1) over the magnetic layer; and a metallic reflecting layer (3) adjacent the optically variable effect generating layer and comprising an array of spaced metallic regions shaped as regular polygons.
Abstract: A security device includes an optically variable device (OVD) having diffraction-based micro-optics including at least one moiré magnified visual representation of a micro-object. A diffractive structure provides micro-objects with unique optical effects when the OVD is viewed through the micro-object structure from a predetermined relative observation point. In addition to magnifying the micro-objects, the diffractive structure can impart optical effects such as change in observed color, enhanced contrast, animation of the observed visual representation, and change in size or shape of the observed visual representation. The micro-objects and the diffractive structure can be disposed on the same or different portions of a substrate. A method of making OVDs, and an article employing such OVDs are also disclosed.

Abstract: An optical disc structure for playback by a read-out device is described. The optical disc structure includes a first layer with first content recorded thereon. A second layer is coupled to the first layer. The second layer has first content and second content recorded thereon. The disc of the present principles makes use of the fact that a less than full capacity DVD9 disc leaves available recording space after the end of program area and required lead-out area on the second of the two data layers of a DVD9 disc.

Abstract: A shield for use in resisting reading of radio frequency chips includes a flexible non-metallic substrate having a metallic coating. The shield may be incorporated into a book such as a passport, an envelope, a folder, or removably adhered to an article having a radio frequency chip disposed thereon.
Abstract: The present invention provides an informational article on which variable information is inserted. The informational article includes a substrate having a zone for inserting the variable information. A visual security device, such as an optically variable ink, a special film, or combinations thereof is disposed in the zone on the substrate. The visual security device is sized and arranged such that at least a portion of the variable information is adapted to being inserted over the visual security device.
