摘要： Self-cleaning banknotes are provided using coatings, inks and additives which are photo-active and catalytic to reactions which are effective in breaking up organic contaminants or dirt to allow for the self-cleaning of banknotes by ambient light exposure as well as the cleaning of processed banknotes using equipment with more intense optical excitation, thus increasing their usable life. The invention is usable with all substrates and particularly polymeric substrates such as biaxially-oriented polypropylene (BOPP). The invention further discloses a system which allows a certain class of fitness parameters to cause these banknotes to be redirected to a cleaning module, be revaluated, and then either returned to circulation or rejected and/or destroyed. In addition, inks which are photo-catalytic can be used for extending the life of the banknotes in printed regions.

摘要： A method of using a dye sensitized solar cell includes providing a dye sensitized solar cell having a first electrode having a transparent substrate of a first refractive index, a second electrode having a second transparent substrate of a second refractive index comparable to the first refractive index, and an electrolyte solution in a gap between the first electrode and second electrode. The electrolyte solution is removed from the gap and replaced with an inert fluid having a third refractive index comparable to the first refractive index and the second refractive index to allow light to pass through the cell substantially unrefracted. Alternatively, the inert fluid is in the gap between the first electrode and second electrode, and the inert fluid is removed from the gap and replaced with an electrolyte solution.

摘要： A magnetically addressable bistable film includes a polymeric substrate impregnated with polymeric microcapsules that contain liquid-suspended magnetically orientable or magnetophoretic material. The material is subject to reorientation either in the plane or perpendicular to the plane of the film, as well to forces of attraction, due to an external magnetic field. The two states provide sufficient difference in light reflectivity to create visible contrast by addressing the film locally, either on a pixel-by-pixel basis or by spatially patterning the driving magnetic field itself. The congregation of magnetophoretic materials in one portion of the microcapsule may also provide sufficient difference in light reflectivity to create visible contrast.

摘要： A marking system that includes forming at least one marking in or on an article, wherein the image formed is not visible to the unaided human observer, and further contains at least one digital watermark. The digitally watermarked image comprises emissive and photoabsorptive portions. The digitally watermarked image is applied using a substance reactive to a predetermined excitation source, and exposure to ultraviolet light. Other traditional techniques, such as printing with fluorescent inks may be used in combination. The digitally watermarked image is subsequently observable upon exposure to the predetermined excitation source. The digitally watermarked image may be observed and decoded by appropriately configured detection systems, wherein the information obtained may be used for purposes including, but not limited to, authentication and security of the article or information contained within the article.

摘要： Systems and methods for using microscopic capsules containing orientable materials for document security and processing applications are presented. A security application comprising a medium having a substrate and a plurality of microcapsules is disclosed. The microcapsules contain magnetically orientable material and a liquid. The magnetically orientable material is oriented in a first alignment. Application of a magnetic field to the medium orients the magnetically orientable material to a second alignment, thereby altering the opacity of the medium. Magnetic material may also be dragged into a concentrated arrangement by a magnetic field, thereby altering the opacity of the medium.
