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： An apparatus is used with an ink jet print head in an ink jet printer. The apparatus includes a print head protector that surrounds a print head. A substantially continuous slot is provided along a perimeter of the bracket and a filter is located in the substantially continuous slot. An inlet in fluid communication with the substantially continuous slot enables a positive pressure air supply to be coupled to the inlet. The air entering the inlet flows through the filter in the slot and the filtered air flows outwardly away from the print head.

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.

摘要翻译： 基于随机过程的选择性替换方法和系统使用固有的冗余，例如在具有全宽颜色的四色彩色打印系统中。 由于四种或更多种颜色的吸收光谱通常在一定程度上重叠，所以存在可用于减少伪像（例如条纹）的冗余。 由于人类视觉系统对于色度变化的敏感程度要比亮度变化（匹配缺失颜色的像素的亮度）与原始颜色的亮度或邻近该像素的像素的亮度相匹配 以减少由缺失颜色引起的伪像的严重性，同时减少替换过程本身引入任何其他工件的机会。
