Disclosed are a system and a method for monitoring a relative position of a moving object. The system essentially includes at least one positioning and transmitting device and a signal receiving and processing device, each equipped with a radio frequency identification (RFID) signal transceiver. The RFID signal transceiver of the signal receiving and processing device receives radio signals transmitted by the RFID signal transceiver of each of the positioning and transmitting devices, thus enabling the signal receiving and processing device to track one or more moving objects each carrying one such positioning and transmitting device and determine the position or positions of the one or more moving objects relative to the signal receiving and processing device.

A method and apparatus for realizing service protection are provided. The method includes the following steps: determining paths corresponding to automatic protection switching (APS)/protection communication channel (PCC) overhead bytes that are available to all nodes in a service protection trail; selecting a path for service protection from the determined paths corresponding to the APS/PCC; and using the selected path for implementing the service protection. Therefore, it is ensured that several service protections using APS/PCC may coexist in an optical transport network (OTN) and different kinds of service protection can be easily distinguished from one another.

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.

A method for realizing interaction of optical channel data unit (ODUk) protection tangent rings are provided. A node used for protection of the ODUk and a receiving unit, a sending unit, a protected receiving unit and a protected sending unit on the node are selected. A connection between a receiving service unit and the protected sending unit with the same transmission direction on the node is established, or a connection between a sending service unit and the protected receiving unit with the same transmission direction on the node is established. Two virtual nodes are established on the node if the node is an intersection node, and connections between the receiving service unit and the protected sending unit, and between the sending service unit and the protected receiving unit are established respectively in each direction of both directions through one of the virtual nodes.

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.

A stamped ball socket includes a base having a recess defined in a top thereof and a spherical hole is in communication with the recess. A plate is fixedly to the top of the base and has a through hole. At least two lock-in fingers extend inward and inclinedly from an inner periphery of the through hole and are located in the recess. An adjuster has a pivot ball which extends through the through hole of the plate and is received in the spherical hole of the base. The lick-in fingers are engaged with the pivot ball.
