  • Patent number: 6970152
    Abstract: A column driver for a graphics display has reduced power consumption by sharing power between upper and lower column amplifiers. The upper column amplifier operates over an upper supply range, while the lower column amplifier operates over a lower supply range. The upper and lower amplifiers have the substantially the same quiescent operating current such that the total operating current for the column drivers in the graphics display is reduced by a factor of two. Each column amplifier can be driven over half of the power-supply range such that lower voltage amplifiers may be employed for the column driver amplifiers.

  • Patent number: 6900779
    Abstract: A process and system for interactively displaying large (more than 1 million voxels) volumetric 3D images utilizing a sequence of helical slices of a 3D data set to generate a series of 2D images on a reflective surface of a light modulator. The series of 2D images generated on the light modulator are projected into a volumetric 3D-space display using an illumination light source and projection optics. Voxels in 3D space are illuminated for each 2D projected image, each voxel being located at its corresponding spatial location. A pulse from a wireless pulsed laser pointer forms a 3D bright voxel within the display volume. The pulse signal is synchronized with the rotating helix, and the orientation of the pointer and the phase of the pulse are controlled by the user to specify a 3D point in 3D space. A wireless receiver provides six degree-of-freedom (DOF) position of the spatial location of the pointer, as well as the phase signal.

  • Patent number: 6900777
    Abstract: A video interface linking a base station with a remote display, e.g., a head-mounted display, converts input video signals from NTSC or PAL formats into modulated video signals containing repetitive sequences of frame times with embedded audio and control signals. Each frame time includes equal consecutive color field times. Frame rates are converted by inserting selected repeating color frames into the datastream. Bursts of image information occupy a portion of each field time. During each data burst, the display is loaded with pixel luminance data. Between bursts, the display is illuminated by a color LED. Two video displays can be driven alternately, i.e., the first display loads while the second is illuminated. The modulated video signal can travel through the atmosphere on an infrared (IR) beam with a wavelength between 700 nm and 1100 nm. In one embodiment, the beam is scattered from a diffuse reflecting surface. Alternatively, the beam is emitted from an array of infrared light emitting diodes (LEDs).

  • Patent number: 6753829
    Abstract: To change image quality in accordance with the image to be displayed, a color filter plate 3 is driven to sequentially split the white light incident on an A portion into red, blue, and green light beams to irradiate a liquid crystal panel, thus displaying a full-color image by a so-called field sequential scheme. In this case, if a sector region 4BG of an auxiliary filter plate 4 is always matched to the A portion (FIG. 2A), the quality of a full-color image is defined by the color filter plate 3, resulting in an increase in luminance. In contrast to this, when a red filter section 3R and auxiliary red filter section 4R are synchronously driven to be simultaneously irradiated with white light, the quality of a full-color image is defined by both the color filter plate 3 and the auxiliary red filter section 4R. As a consequence, an image with excellent color reproducibility is obtained.

    Abstract: An ink jet maintenance station for an ink jet printer with radially arranged printheads around a print drum. The maintenance station is located axially outward of the print drum, and includes a cylinder with caps and wipers at the cylinder periphery. A cam system operates upon rotation of the cylinders to elevate the caps into sealing relationship with the printhead nozzle plates. The nozzle plates are wiped by rotation of the cylinder to sweep the wipers across the nozzle plates. During non-service periods, the maintenance station does not interfere with printer carriage movement.

  • Patent number: 6727868
    Abstract: The terminals for a display content control signal or product specification control signal output by an integrated circuit for detecting a display format of a display panel are all connected to a corresponding drive pattern of a circuit board used for conveying drive signals to the display panel through a connector, so that a plurality of different types of displays may be driven without requiring different dedicated electronic circuits modified for each type of display. A plurality of different display panels each having a unique display format are prepared for use in different destinations, and the drive pattern on the display panel indicates the destination, thereby making possible to provide a display content switch section or product specification switch section within the display panel.

  • Publication number: 20040061665
    Abstract: A display device comprises a light guide and a movable element. By locally exerting a force on the movable element by means of selection means, optical contact between the movable element and the light guide can be brought about. Light emanates from the display device at the locations where optical contact takes place. Measures are taken to employ the force exerted by the selection means as efficiently as possible. This can be achieved by making the force act at the location where the optical contact takes place and/or by reducing other adhesive forces (caused, inter alia, by differences in pressure, static charging, surface stresses, van der Waals' forces and/or chemical forces).
