Abstract: An adhesive-backed article having a compliant film with a pressure sensitive adhesive bonded to one surface of the film. The pressure sensitive adhesive includes a microstructured surface opposite the compliant film. The microstructured surface defines channels in the adhesive. The channels create pathways for the egress of fluids. Upon application onto a substrate, the channels and structures wet out to render the microstructured surface substantially undetectable when viewed from the exposed surface of the article.

Abstract: A receptor medium with a sheet having an optically transmissive microembossed imaging surface as one major surface thereof. The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, and combinations thereof. The microembossed medium unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium and also Moire' effects but also provides sufficient optical transmissivity to be useful as overhead transparency media, backlit signage, and the like. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained without creation of the Moire' effects. Methods of making and using the inkjet receptor medium are also disclosed.

Abstract: Assemblies containing a substrate with pockets for electromagnetically responsive particles can be made for a variety of uses, including, for example, display media, lenses, and color-changing fabric. The arrangement of these pockets can be selected to provide higher particle density than previously realized. The assembly includes an assembly substrate, particles, and a top coat layer.

Abstract: A receptor medium with a sheet having an embossed imaging surface as one major surface thereof The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, and combinations thereof. The embossed medium unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained, Methods of making and using the inkjet receptor medium are also disclosed.

Abstract: Rear projection screens include a film layer having a plurality of lenses for diverging light horizontally and vertically. The horizontal viewing angle created by the lenses may be different from the vertical viewing angle. The light may be directed by the lenses in a particular direction, so that the direction of the maximum intensity light does not lie parallel to an axis normal to the screen surface. The lens film may be combined with an isotropic light disperser, such as a bulk diffuser.

Abstract: An excimer laser projection ablation system provides less than the necessary amount of illumination to a substrate to completely ablate a structure. The system then moves the substrate a distance less than the image field at the substrate and provides an additional level of illumination. The system continues to move the substrate and provide additional illumination until the structures are fully ablated. The method and system for performing an improved step and repeat process preferably are used to create uniform repeating structures or three-dimensional structures.
