  • Patent number: 7708317
    Abstract: A hollow pipe connector is described for interconnecting opposed ends of two hollow pipes in abutting end-to-end relationship. Preferably, but not exclusively, the pipes are hollow pile cylinders of circular cross-section. The connector is formed by two flat metal plates each having interconnecting slots whereby the plates are coupled together to form a connector of X-cross-section. Each of the plates have outer side edges having opposed sloped edge portions on a respective side of an arresting raised projection formed in the outer edge in a mid-section thereof. The sloped edge portions slope inwardly towards a respective one of the opposed ends of the connector member. The connector engages opposed end portions of pipes coupled together by a frictional retaining force exerted on the inner walls at opposed ends of the coupled pipes.

  • Patent number: 7705864
    Abstract: A display controller system is controlled to provide a display surface zoom using hardware scaling from user input at the operating system, application program or hardware level. User input defining coordinates of a frame portion within a frame buffer memory is obtained, and a resolution of the zoom display device is determined. An aspect ratio of the zoom portion defined by the user input is adjusted to correspond to the zoom display device resolution. The display controller system is programmed to implement the display surface zoom to provide a full screen view of the zoom portion on the zoom display device. In the display controller system, the zoom portion of the frame buffer memory is scaled, converted into a display signal and output.
