A system and corresponding methods are disclosed for applying a dampening fluid to a reimageable surface of an imaging member in a variable data lithography system, without a form roller. In one embodiment, the system includes subsystems for converting a dampening fluid from a liquid phase to a dispersed fluid phase, and for directing flow of a dispersed fluid comprising the dampening fluid in dispersed fluid phase to the reimageable surface. The dampening fluid reverts to the liquid phase directly on the reimageable surface. In another embodiment a continuous ribbon of dampening fluid may be applied directly to the reimageable surface. This embodiment includes a body structure having a port for delivering dampening fluid in a continuous fluid ribbon directly to the reimageable surface, and a mechanism, associated with the body structure, for stripping an entrained air layer over the reimageable surface when the reimageable surface is in motion.

Various structures or components can include plated surfaces or other parts. For example, an article can include a base and a plated part with a limit artifact that results from plating adjacent a non-plateable surface; the limit artifact can be disposed away from the base. Exemplary limit artifacts include lack of protrusions, smooth upper surfaces, and curved surfaces, where a curved surface can transition between a smooth upper surface and an irregular side surface. Exemplary plated structures can be tube-shaped or cup-shaped, with an opening at a top end and, around the opening, a lip with a limit artifact. Wall-like structures can similarly have limit artifacts at their top end. If plating on a mold's side surface, the non-plateable surface can be the lower surface of an overhanging polymer disk or structure positioned on the mold. Plated tubes and wall-like structures can be employed in microfluidic structures.

Cells can include variable volumes defined between a flexible structure, such as a polymer layer, and a support surface, with the flexible structure and support surface being attached in a first region that surrounds a second region in which they are unattached. Various adhesion structures can attach the flexible structure and the support surface. When unstretched, the flexible structure can lie in a flat position on the support surface. In response to a stretching force away from the support surface, the flexible structure can move out of the flat position, providing the variable volume. Electrodes, such as on the flexible structure, on the support surface, and over the flexible structure, can have charge levels that couple with each other and with the variable volume. A support structure can include a device layer with signal circuitry that provides a signal path between an electrode and external circuitry. One or more ducts can provide fluid communication with each cell's variable volume. Arrays of such cells can be implemented for various applications, such as optical modulators, displays, printheads, and microphones.

Systems and methods for aligning substrates that include microstructures. The microstructures may be electronic or micromechanical components. The system includes a first substrate having a first alignment structure and a second substrate having a second alignment structure. The substrates are positioned so that the first alignment structure contacts the second alignment structure without the substrates directly contacting each other, and one of the substrates is adjusted in relation to the other substrate until the first and second alignment structures lock into place. After alignment, the microstructures on the first substrate and the second substrate may establish a connection with or be positioned in near proximity to each other.

An improved method of forming a display is described. The method describes depositing droplets of a display fluid into a sealing solution. The sealing solution seals the droplets of display fluid such that each droplet forms a miniature cell of display fluid. Electrodes address charged particles in the miniature cells to form viewable images for use in a display.

Several traveling wave grid systems are disclosed that may be used to concentrate and form highly localized regions of bio-agents or other charged species. In addition, specific detection systems are described that enable currently available detectors and sensors, including those to be developed in the future, to be used for measuring the presence and concentration of certain bio-agents or charged particles, which otherwise are present at concentrations too low to readily detect or measure.
