    摘要: A structure for a micro-device is fabricated by forming: a first layer of sacrificial material, a layer of structural material over the first sacrificial material layer, a second layer of sacrificial material over the structural material layer and a protective layer over the second sacrificial material layer. A release etch is used to remove the first and second sacrificial material layers at approximately the same rate. A structural feature may also be fabricated by forming: a first layer of a first material; a layer of structural material over the first layer of the first material; at least one cut in the structural material layer; and, a first layer of a sacrificial material, different from the first material, over the structural material layer such that an interface is created between the first layer of the sacrificial material and the first layer of the first material at the at least one cut.

    摘要: Selective replacement methods and systems based on a stochastic process use a redundancy inherent, for example, in a four-plus color printing system that has full-width colors. Since the absorption spectra of the four or more colors usually overlap to some extent, there is a redundancy that can be used to reduce artifacts, such as streaks. Since the human visual system is much less sensitive to chrominance changes, than to luminance changes, matching the luminance of a pixel where a color is missing, to the luminance of the original color or to the luminance of the pixels that neighbor that pixel can adequately to reduce the severity of the artifact caused by the missing color while reducing the chance that the replacing process itself introduces any additional artifacts.

    摘要: System and method for encapsulating edges of a paper in digital printing systems. A spray applicator can include a set of stationary sprayers with spray nozzles, a set of transfer rollers and an inkjet print head. The stationary sprayers can be positioned at both marginal ends of the paper. The stationary sprayers apply the fluid through the spray nozzles at edges of the moving paper to encapsulate the edges of the paper such that loose paper fibers and debris are bound to the paper. The fluid can be applied when the transfer rollers can pass the moving paper through a printer or printing press. Thus, the system can protect various subsystems of the printer or printing press against contamination due to the loose paper fibers and debris.

    摘要: A maintenance method for an ink jet imaging device comprises ejecting drops from a plurality of ink jets to successively form a plurality of images on the image receiver. Inter-image intervals between the ejection of drops to form one image in the plurality of images and the ejection of drops to form a successive image in the plurality of images are detected. A plurality of drops is ejected from at least a portion of the ink jets in the plurality of ink jets during at least one detected inter-image interval. The plurality of ejected drops having at least one drop ejecting characteristic selected from: a drop mass for the plurality of drops being greater than a standard drop mass; a drop ejecting frequency for the plurality of drops being lower than a standard drop ejecting frequency; and a substantially sequential drop ejecting pattern for the plurality of drops.
