  • Patent number: 10342115
    Abstract: Disclosed is a high-frequency-tuning sliding electrical contact. The contact includes a tuning ring which is composed of an inner elastic piece, an upper base, an outer elastic piece and a lower base. Pull rods are welded to an upper side face of the upper base, and upper ends of the pull rods are driven to move up and down by a motor, so that the tuning ring slides up and down between the outer sleeve and the inner sleeve along the pull rods. The overall structure of the novel electrical contact is simple, compact and economical. The disclosure reduces joule heat produced by contact resistance and prevents contact surface fusion welding or conductive damage, and is especially suitable for tuning in a small gap range.

    Abstract: Embodiments of the present invention disclose a service transmission processing method, a node device and a network system are provided. One method includes: receiving service data after relay processing by a 3R relay node, where the relay processing includes terminating and regenerating an Optical Channel (OCh) of the service data, and when the OCh is terminated, transparent transmission is performed on an Optical channel Transport Unit (OTU); and performing defect detection on a path of the OTU to obtain a detection result of the path of the OTU. Another method includes: obtaining an overhead in an Optical Transport Network (OTN) frame; and judging whether the overhead includes a Client Signal Fail (CSF) inserted after a signal fails, and if the overhead includes the CSF, determining a path where a defect occurs according to the CSF.

  • Patent number: 8997074
    Abstract: Techniques for replacing ROM-based (Read-Only Memory) DLLs (Dynamic Link Libraries) in a Windows CE type embedded operating system such that the target DLL is replaceable by the hook DLL, and the target DLL is callable by the hook DLL but not callable directly by any other applications after loading of the hook DLL. The techniques enable replacement irrespective whether the hook DLL and the target DLL have the same name and irrespective of which DLL is loaded first. The techniques change the file name of the target DLL in a list of loaded DLL modules by a trusted program that executes in the full kernel mode.

  • Patent number: 8498965
    Abstract: One embodiment relates to a computer-implemented method for generating difference data between reference and target files. A difference engine implemented using a computer receives the reference and target files. The difference engine performs a first procedure to generate difference data representing the difference between the reference and target files if the size of the reference file is less than a first threshold size. The difference engine performs a second procedure to generate the difference data if the size of the reference file is less than a second threshold size and greater than the first threshold. The difference engine performing a third procedure to generate difference data if the size of the reference file is greater than the second threshold size. Other embodiments relate to apparatus for generating difference data between reference and target files and for reconstructing the target files from the reference files using the difference data.
