    摘要: Method and apparatus for dynamically allocating IP addresses in a wireless IP network. IP address servers determine the requisite IP address pools and guard bands for individual network cells to guarantee fair access to the network and facilitate handoff host handoff from a prior cell to a new cell. IP address servers also prioritize handoff and resident hosts that request an IP address from the IP address server. In particular, IP address servers assign a higher priority to handoff hosts over resident hosts that request an IP address from an IP address server in order to maintain a preestablished handoff host network connection instead of dropping a handoff host connection in favor of a new resident host network connection. Finally, each cell is allocated a minimum number of IP addresses to ensure a certain level of fair access to the network regardless of the cell wherein a handoff or resident host resides.

    摘要: A virtual structured information system or a virtual database is developed and presented in the framework of an information theory for multiple source information systems such as databases. A virtual tree structure is built from virtual nodes in main memory which contain no raw data. The virtual nodes and virtual trees provide general non-data virtual structure, like cross-table nodes, for systematic information manipulations such as on-line analytical processing in a structured information system.

    摘要: A vacuum cleaner charging dock comprising a base and a bracket is provided. The bracket is arranged on one side of the base and is provided with a charging socket for charging a vacuum cleaner, while a positioning slot is arranged on another side of the base, the positioning slot is used for containing a floor brush of the vacuum cleaner, the positioning slot is provided with a plurality of convex teeth, which are used for rubbing with a rolling brush on the floor brush. The vacuum cleaner charging dock is provided with convex teeth, and the rolling brush of floor brush has deformation contact with the convex teeth. When the rolling brush starts to rotate, the convex teeth are easy to perform frictional rotation. Then dust and sewage on the rolling brush are shaken off into a positioning slot to complete the cleaning to the rolling brush, which is convenient and efficient.

    摘要: A method and system for adjustable 3-dimensional content are described in which a viewer can adjust the depth range according to the viewer's own visual comfort level and/or viewing preference. The depth change is achieved by shifting the left and right images of stereoscopic content image pairs so that corresponding pixels in the shifted left and right images of a stereoscopic pair exhibit a new horizontal disparity sufficient to achieve the desired depth change. By shifting the left and right images in an image pair, content objects in the scene can appear closer to, or farther away from the viewer than those same objects in the un-shifted image pair. This technique achieves a viewer controlled customization of the sensation of depth in the stereoscopic 3-dimensional content.
