  • Patent number: 10798844
    Abstract: An apparatus provides an extendable rail assembly including a track for securing to a rack, a first rail slidably coupled to the track, and a second rail slidably coupled to the first rail. The first rail is movable relative to the track between retracted and extended positions, wherein the first rail includes first and second rail sections coupled together by a pivot joint. The second rail is movable relative to the first rail between retracted and extended positions. Furthermore, with the first rail in the extended position and the second rail in the extended position, the pivot joint allows the second rail and the second rail section of the first rail to pivot relative to the track and the first rail section of the first rail. A pair of rail assemblies may be secured to a rack to support a member, such as a server.

  • Patent number: 8788980
    Abstract: The invention is directed to a method for checking a die seal ring on a layout. The method comprises steps of receiving a digital database of a layout corresponding to at least a device with a text information corresponding to the layout. Tape-out information corresponding to the layout is received. A checking process is performed according to the digital database of the layout and the tape-out information and, meanwhile, a mask design procedure for designing a mask pattern corresponding to the layout is performed by using the digital database of the layout, the text information and the tape-out information. A result of the checking process is recorded in an inspection table corresponding to the layout.
