  • Publication number: 20070103473
    Abstract: A display apparatus and a signal processing method thereof are disclosed. The display apparatus comprises a micro-controller, a detection module, an image processor, a first bus, and a second bus. The detection module is used to detect a status of the display apparatus. The image processor is used to process signals from the micro-controller. The first bus is used to electrically connect the image processor and the micro-controller. The second bus is used to electrically connect the micro-controller and the detection module. The detection module transmits the status of the display apparatus to the micro-controller via the second bus. The micro-controller communicates with the image processor via the first bus. Because of the micro-controller and the second bus, the workload of the image processor and the first bus is decreased.

  • Patent number: 5651565
    Abstract: A locking structure for two telescoping tubular members is provided with an outer tube member and an inner tube member slidable inside the outer tube member. An expansion member is located within the outer tube member. The expansion member contains at least two tapered members each having innermost and outermost portions, the outermost portions being spaced no more than 1/2 inch from each other. On the expansion member is an outer tube pressure member shaped to fit the expansion to member and disposed between said the expansion member and the inner surface of the outer tube member. The expansion member may be attached to the inner tube member. The expansion member is moved in opposite directions inside the outer tube member so that when said expansion member is moved in a first direction, pressure is directly applied to the outer tube pressure member which in turn applies pressure to the inner surface of the outer tube member thereby maintaining the inner and outer tube members in a locked position.
