  • Image forming apparatus and image data transfer method
    Publication number: 20060007472
    Abstract: An image forming apparatus that forms a multi-color image by combining images of different colors includes: an image data output unit that outputs the image data of each of the different colors through transmission paths allocated for the respective different colors; and a control unit that outputs color images to form the multi-color image to the image data output unit, and notifies the image data output unit which transmission path is to be used to transmit the image data of each of the different colors. When only a designated color among the different colors is used to form an image, the control unit converts the format of the image data of the designated color, and outputs the converted image data to the image data output unit.

  • Halftoning using dot and line screens to avoid two and three color moiré
    Patent number: 6985256
    Abstract: Moiré free color halftoning is achieved through the use of two dot screens and one or two line screens. The line screens may be, for example hybrid line screens. Frequency vectors associated with the screens combine to produce moiré frequency vectors representing moiré frequencies above or below the visual range. In one embodiment lines screens are used to halftone yellow and black separations and dot screens are used to halftone cyan and magenta separations. The dot screens are oriented at 15 and 75 degrees. The line screens are oriented at 45 and 135 degrees. Selected screens and screen orientations minimize screen interaction with mechanical or optical artifacts of a rendering device, thereby minimizing mechanical and optical moiré.

  • LED bar array high addressable imaging in 2-dimensions
    Patent number: 6985627
    Abstract: An imaging apparatus includes an input that receives a stream of image pixels such as high addressable bits, multiple bits per pixel or binary image bits representing an input image and a processor that processes and directs signals to an LED bar that selectively exposes areas of a photoreceptor. The exposed areas of the photoreceptor form a latent image, controlled by the processor, of areas of varied exposure based on surrounding pixels. The processor examines the pixels to determine an image structure beneficially adaptable to varied exposure and selects a pixel for varied exposure, such as increased or decreased exposure or altered timing to apply the pixel.

  • Thermal actuator with offset beam segment neutral axes and an optical waveguide switch including the same
    Patent number: 6985651
    Abstract: A thermal actuator comprises a substantially straight beam. The beam has a beam length and a beam mid-point. The beam comprises a plurality of beam segments with beam segment lengths. Each beam segment has a beam segment neutral axis, thus forming a corresponding plurality of beam segment neutral axes. The beam segment neutral axes are offset along the beam length based on a predetermined pattern. As the beam is heated by an included heating means, the beam buckles. The buckling of the beam, in turn, causes the beam mid-point to translate or move in the predetermined direction. The beam mid-point movement, in turn, operates an included optical waveguide switch. The heating means comprises any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.
