Abstract: The present invention relates to a display configured to display images that includes multiple display elements capable of controlling light within a visible-light spectrum. The display elements are arranged over a display surface of the display. The display also includes one or more receivers arranged with the display elements over the display surface of the display. The receivers are coupled with the display elements and receive transmitted image information. The receivers activate the display elements in response to, and in correspondence with, the image information.

Abstract: A fuel cell flow regulator includes a fuel cell fuel flow path, the fuel flow path including a solid-state material for regulating a flow of fuel along the fuel flow path by adsorption.

Abstract: An emission device includes a plurality of electron emitter structures of varied geometry that have a conducting layer deposited thereon. The conducting layer has openings located at tunneling sites for each of the electron emitter structures. The tunneling sites facilitate electron emissions from each of the varied geometry electron emitter structures upon voltage biasing of the conducting layer relative to the electron emitter structures.

Abstract: A re-recordable data storage medium is disclosed. One embodiment of the medium includes a dielectric material and a filler material. The dielectric material is organized in columnar channels over which memory cells are logically distributed. The filler material is within the columnar channels to realize the memory cells. The filler material of each memory cell has at least a first configuration and a second configuration. The first configuration corresponds to a first storable logical value, and the second configuration corresponds to a second storable logical value.

Abstract: A method for fabricating tiny field emitter tips across the surface of a substrate. A substrate is first exposed to reactive molecular, ionic, or free radical species to produce nanoclusters within a thin surface layer of the substrate. The substrate may then be thermally annealed to produce regularly sized and interspaced nanoclusters. Finally, the substrate is etched to produce the field emitter tips.

Abstract: A ticket including a base member, a discolorable member carried by the base member, and a discoloration system carried by the base member. The discoloration system is initially configured such that the discoloration system selectively discolors a first predetermined portion of the discolorable member in response to the application of a first energy pulse without discoloring a second predetermined portion of the discolorable member. The discoloration system is also adapted to be reconfigured by the first energy pulse such that the second predetermined portion of the discolorable member will be discolored in response to the application of a second energy pulse.
