摘要： An apparatus for developing a latent image recorded on a surface, including a housing defining a chamber storing a supply of developer material including toner and carrier beads. A toner donor member is spaced from the surface and is adapted to transport toner to a region opposed from the surface. A magnetic roller conveys the toner material in the chamber of the housing onto the donor member. An electrode member is spaced near the surface of a donor roll, the electrode member electrically biased by a power supply to detach toner from the donor member as to form a toner cloud for developing the latent image. A power supply controller, in communication with the power supply, is adapted to adjust the electrode member electrical biasing to avoid air breakdown induced contamination of the electrode member with toner.

摘要： Interdigitated electrodes on a donor roll enable uncharged toner to be picked up from a fluidized bed reservoir. This layer of toner is subsequently charged by exposure to a corona device and delivered to a development zone, where it is used to develop an electrostatic latent image. Residual toner on the donor is neutralized by exposure to a second corona device and then stripped for return to the fluidized bed by applying an AC voltage between adjacent donor electrodes. So-called ion charging of the toner is known to cause the particles to have low adhesion, allowing development with DC fields alone. Optionally, an AC voltage can also be applied to adjacent donor electrodes in the development zone to enhance particle release. In addition to providing a means to impart adequate flow to the toner in this single component development system, the fluidized bed reservoir, in conjunction with ion charging, also provides a means for blending dry powder toners to achieve custom color development.

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。
