20160101643 | SINGLE LAYER IMAGE PROJECTION FILM - A single layer image projection system that is made up of an arrangement of optionally reflective arcuate elements having an upper arcuate surface, a lower surface, and an arcuate area bounded by the upper arcuate and lower surfaces, and an optionally reflective pattern of image relief microstructures disposed on or within at least some of the upper arcuate surfaces of the arcuate elements, is provided. The arrangement of optionally reflective arcuate elements and the optionally reflective pattern of image relief microstructures are in a single layer and interact to project one or more images. For an upper arcuate surface with convex surface curvature, the image relief microstructures extend downwardly from this surface terminating within the arcuate area, and for an upper arcuate surface with concave surface curvature, the image relief microstructures extend upwardly from this surface terminating within an area defined by the curvature of the upper arcuate surface. Transmission of light through the system, reflection of light from the system or a combination thereof forms one or more images. | 04-14-2016 |
20150217550 | PROCESS FOR TRANSFERRING MICROSTRUCTURES TO A FINAL SUBSTRATE - A process and a transfer film for transferring microstructures to a flexible or rigid final substrate that offers advantages in both speed and precision is provided. The inventive process involves subjecting a transfer film in a continuous roll-to-roll process to the following operations: either forming microstructures on, or transferring microstructures to a surface of the transfer film; and then transferring the microstructures from the transfer film onto a surface of the final substrate. The microstructures are single or multi-layer structures that are made up of: voids in a substantially planar surface, the voids optionally filled or coated with another material; raised areas in a substantially planar surface; or combinations thereof. | 08-06-2015 |
20150070350 | SECURITY DEVICE FOR PROJECTING A COLLECTION OF SYNTHETIC IMAGES - A security device for projecting a collection of synthetic images as well as a computer-implemented method for producing such a security device are provided. The synthetic images may represent different viewpoints of a target object or image that change from one viewpoint image to another viewpoint image as the location of the observer changes relative to the device. The nature of each synthetic image can, however, be completely arbitrary, much like the images that are provided by a display device such as a television or computer monitor. In an exemplary embodiment, a special symmetry is used to generate the synthetic images, which allows the device to be manufactured without regard for registration. | 03-12-2015 |
20140376091 | OPTIONALLY TRANSFERABLE OPTICAL SYSTEM WITH A REDUCED THICKNESS - An optionally transferable optical system with a reduced thickness is provided. The inventive optical system is basically made up of a synthetic image presentation system in which one or more arrangements of structured image icons are substantially in contact with, but not completely embedded within, one or more arrangements of focusing elements. The focusing element and image icon arrangements cooperate to form at least one synthetic image. By way of the subject invention, the requirement for an optical spacer to provide the necessary focal distance between the focusing elements and their associated image icon(s) is removed. As a result, overall system thicknesses are reduced, suitability as a surface-applied authentication system is enabled, and tamper resistance is improved. | 12-25-2014 |
20140232809 | LASER MARKED DEVICE - An optical device projecting one or more synthetically magnified images that has been laser marked with one or more static two dimensional (2D) images is provided. The static 2D image(s) laser marked on or within this device and the synthetically magnified image(s) projected by this device help determine the authenticity of a document (e.g., passport data page) or product that employs it. Several embodiments of the inventive device also offer increased resistance to tampering or alteration and wear. | 08-21-2014 |
20130004738 | LOW CURL OR CURL FREE OPTICAL FILM-TO-PAPER LAMINATE - An optical film material suitable for use in low curl or curl free optical film-to-paper laminates is provided. The inventive optical film material includes a light-transmitting polymeric optical spacer or carrier film that has a linear coefficient of thermal expansion (CTE) of less than about 25×10 | 01-03-2013 |
20120194916 | LASER MARKED DEVICE - An optical device projecting one or more synthetically magnified images that has been laser marked with one or more static two dimensional (2D) images is provided. The static 2D image(s) laser marked on or within this device and the synthetically magnified image(s) projected by this device help determine the authenticity of a document (e.g., passport data page) or product that employs it. Several embodiments of the inventive device also offer increased resistance to tampering or alteration and wear. | 08-02-2012 |
20110209328 | MICRO-OPTIC SECURITY AND IMAGE PRESENTATION SYSTEM PRESENTING A SYNTHETICALLY MAGNIFIED IMAGE THAT APPEARS TO LIE ABOVE A GIVEN PLANE - A film material utilizing a regular two-dimensional array of non-cylindrical lenses to enlarge micro-images, called icons, to form a synthetically magnified image through the united performance of a multiplicity of individual lens/icon image systems. The synthetic magnification micro-optic system includes one or more optical spacers ( | 09-01-2011 |
20110019283 | TAMPER INDICATING OPTICAL SECURITY DEVICE - A tamper indicating optical security device that operates to produce one or more synthetic images is provided. Any attempt to detach (e.g., forcibly remove) this device from an underlying base material will cause one or more layers of the security device to separate or delaminate, rending the device partially or totally inoperable. The inventive device is contemplated for use with, among other things, currency or banknotes, secure documents such as bonds, checks, travelers checks, identification cards, lottery tickets, passports, postage stamps, and stock certificates, as well as non-secure documents such as stationery items and labels. The inventive device is also contemplated for use with consumer goods as well as bags or packaging used with consumer goods. | 01-27-2011 |
20100308571 | OPTICAL SYSTEM DEMONSTRATING IMPROVED RESISTANCE TO OPTICALLY DEGRADING EXTERNAL EFFECTS - A system for projecting one or more synthetic optical images, which demonstrates improved resistance to optically degrading external effects, is provided. The inventive system serves to lock the focal length of the focusing elements in place. In other words, no other transparent materials or layers brought into contact with the inventive system will serve to materially alter the focal length or the optical acuity of synthetic images formed by the system. | 12-09-2010 |
