Abstract: The present invention provides self-disabling tamper evident gift cards, and methods for making and using the gift cards. The gift cards comprise a hidden lower level activation code, and an upper level activation code that is visible. The gift cards incorporate one or more features that render either the lower level or upper level, or both, activation codes unreadable once the lower level activation code is revealed. This prevents card activation at a later time after a first instance when the activation code is accessed.

Abstract: This invention discloses a radiation curable barrier coating composition for application to paper or paperboard substrates that can be applied using a conventional flexographic printing process. The coating composition includes one or more hydrophobic cycloaliphatic radiation curable monomers, one or more alcohol-functional waxes or sterols, and one or more other hydrophobic wax materials. The incorporation of these materials together lowers the MVTR of the coating compared to other radiation curable compositions while also generating improved, higher gloss. This invention also discloses a method to manufacture the coating composition and a preferred method to print the coating composition.

Abstract: Economical production of laser-drilled high-precision, ultra-miniature multiple-via-hole patterns is accomplished by multiplexing the homogenized, shaped, nearly-collimated output of a high-power excimer laser into a modular set of condenser lens/mask/projection lens beamlines. A substrate delivery subsystem provides a continuous supply of film substrate segments as blanks during production. Functional modularization permits the building and easy retooling of a hard-tooling multiple-beamline system powered by a high-power laser. Vertical modularization permits the building of a single-beamline soft-tooling pilot system, which may be used to demonstrate a production technique, or may be used for short production runs, and which may later be incremented with additional vertical subassemblies for additional beamlines.

Abstract: In the manufacturing of flexible, large-area electronic modules such as flat-panel displays (FPDs), the high cost and low yields of currently available patterning equipment represent a significant barrier to cost-effective production. This invention provides a projection imaging system that can pattern very large, flexible substrates at very high exposure speeds with almost any desired image resolution. The master pattern to be imprinted on the substrate is contained on a mask which, similar to the substrate, is made of a flexible material The mask and substrate are scanned by rollers through the object and the image field, respectively, of a 1:1 projection lens. All of the rollers are driven by identical drive systems linked to a common motor; therefore, the scanning of the mask and substrate is perfectly synchronized. Both the mask and the substrate, along with their rollers, are mounted on a linear translation stage.
