  • Method and apparatus for presenting images in a data processing system
    Patent number: 6954548
    Abstract: A method and apparatus in a data processing system for processing graphics image. A determination is made as to whether the graphics image has more than two colors. The graphics image is compressed in response to an absence of a determination that the graphics image has more than two colors to form a compressed image. The compressed image is sent to a client.

  • Method and apparatus in a data processing system for installing appropriate WID values for a transparent region
    Patent number: 6710777
    Abstract: A method and apparatus in a data processing system for updating a buffer containing display information used to display pixels from a first layer and a second layer on a display in the data processing system. Pixels from the first layer and pixels from the second layer are identified in a transparent region. The display information is updated in the buffer for pixels in the first layer in the transparent region. Correct display information is assigned to pixels in the second layer in the transparent region.

  • Method and apparatus in a data processing system for updating color buffer window identifies when an overlay window identifier is removed
    Patent number: 6573904
    Abstract: A method and apparatus in a data processing system for updating a buffer containing display information used to display pixels from a first layer and a second layer on a display in the data processing system. Display information is identified for pixels in the first layer in a region corresponding to a removal of pixels being displayed in the second layer. This identification is performed using a data structure containing display information for displaying pixels in the first layer and pixels in the second layer to form identified display information. Display information in the buffer is updated using identified display information.

  • Method and apparatus for updating a window identification buffer in a data processing system
    Patent number: 6529208
    Abstract: A method and apparatus in a data processing system for updating a buffer used to display pixels from a first layer and a second layer in the data processing system, wherein identification display information for pixels from the first layer and the second layer are stored in the buffer. Pixels are identified for the second layer having opaque pixel types to form a selected set of pixels. Overwriting of display information is prevented for the selected set of pixels in the buffer when updating the buffer.

  • Adapter for centrifuge tube
    Patent number: 5935052
    Abstract: An adapter for use in a fixed angle centrifuge rotor has, in use, a radially inboard and a radially inboard portion. An opening is formed in the radially inboard portion of the adapter. The opening is sized so that substantially no part of the inboard portion of the adapter is exposed during centrifugation to a load that exceeds the ability of the material of the adapter to support itself. The material of the inboard portion of the adapter surrounding the opening has sufficient strength to support itself while under centrifugation. The adapter is fabricated from a light transmissive material. A plug that is slidably disposed and selectably positionable within the opening in the inboard segment of the adapter. The inside surface of the plug having a sealing material thereon that is biased into contact with a tube carried within the adapter.
