Abstract: A process for applying a protective coating to a flex circuit comprises providing a flex circuit having conductive traces on one surface and applying a protective coating in substantially a liquid state to the one surface from a first roller including the protective coating in a pattern thereon. The pattern includes at least one area on the one surface of the first roller that is not covered by the protective coating.

Abstract: A flexible sheet which includes a substrate having at least one visually discernable surface and at least one electroluminescent lamp assembly positioned proximate to the surface and controlled by a suitable power source as well as means for isolating at least one electroluminescent lamp assembly from deleterious interaction with environment external to the flexible sheet. The flexible sheet can be employed in various applications including bound books, functional cards, locational orientation devices as well as in mechanisms for selectively indicating ingress or egress from architectural structures and other safety indicators. At least one component of the flexible sheet with the electroluminescent lamp assembly can be produced by drop ejection.

Abstract: An exemplary printing device and related systems are described. One exemplary printing device includes one or more print cartridges configured to selectively eject generally fluidic material onto a media. At least one print cartridge of the one or more print cartridges is configured to eject a first generally fluidic material comprising a slurried suspension.
