摘要： The invention enables protection of a ring frame transferred via an inter-ring bridge ring node when a fault occurs at the node in a multiring. Ring nodes form a ring protection domain to enable one ring node to be bypassed by using other ring nodes when a fault occurs at this ring node. The TTL value of ring frame to be transferred through the bypass is set to a value obtained by adding the number of hops h to the faulty ring node to a common initial value A in the same two-fiber ring to enable detection of a characteristic TTL value at a bypassing ring node. The bypass for the ring frame is selected with reference to the characteristic TTL value at the bypassing ring node.

摘要： A storage circuit defines a first field for storing first header bits of a first payload signal of a first data unit, a second field, and a third field for storing the first payload signal. The first header bits are equal in number to second header bits of a second payload signal of a second data unit. A division circuit divides the first header bits by a generator polynomial to produce a first error check code. The same generator polynomial is used to divide the second header bits to produce a second error check code. A remainder of division of hypothetical header bits by the generator polynomial is summed to the first error check code to produce a sum which is inserted into the second field of the storage circuit. The hypothetical header bits are greater in number than a total number of bits in the first and second fields, so that the first and second data units can be distinguished from each other by different error check results of the first and second data units.

摘要： There is provided a winding spring for a seat belt winding apparatus which comprises an output drum and a take-up drum. The winding spring is stretched in the S-shaped form between the output drum and take-up drum. In the normal use region of the entire length of the winding spring, the natural radius of curvature of the spring is gradually increased. In the surplus use region of the spring, the natural radius of curvature of the spring is divided into a part where it is gradually decreased and a part where it is kept constant. The natural radius of curvature in the free end portion of the winding spring is increased.

摘要： Between a first pair of termination nodes, a first current-use packet transmission path and at least one first spare packet transmission path are defined. Between a second pair of termination nodes, a second current-use packet transmission path and at least one second spare packet transmission path are defined. When no network fault occurs, packets are transmitted between the pairs of nodes in a 1:1 transfer mode in which the pairs transfer packets via both current-use packet transmission paths only. When a network fault occurs in the first current-use packet transmission path, both transmissions are switched from a 1:1 transfer mode to a 1+1 transfer mode, in which the first pair of nodes transfer packets by using the first current-use packet transmission path and the first spare packet transmission path, and the second pair transfer packets by using the second current-use packet transmission path and the second spare packet transmission path.

摘要： The present invention measures 1-way delay without equipping all nodes with special functionality in a situation in which time has not been synchronized. The delay measurement system of the present invention has a transmission origin node and a transmission destination node which is connected to the transmission origin node through a network including relay nodes, and measures the delay time from the transmission origin node to the transmission destination node direction, wherein the transmission origin node generates a clock. On the basis of the generated clock, delay measurement packets are generated at regular periods. The generated delay measurement packets are transmitted to the transmission destination node. The transmission destination node selects the delay measurement packets from among the received frames. The delay received by the delay measurement packets in the network between the transmission origin node to the node itself is measured.
