    摘要: A transmission source node transmits diagnostic frames where a TTL value is set to the number of hops that is counted until an intermediate node. A relay node decrements the TTL value of the received diagnostic frames, counts the number of diagnostic frames where the decremented TTL value is 0, and recognizes continuity between the transmission source node and the relay node based on the number of transmitted diagnostic frames transmitted from the transmission source node and the number of diagnostic frames where the decremented TTL value is 0.

    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: This communication system is equipped with a plurality of transceiver devices each composed of a transmission device that transmits unit data and a reception device that receives unit data from the transmission device. The transmission devices are connected in series. Each of the transmission devices stores identification information for identifying the device itself. The transmission device accepts unit data from a front stage side. The transmission device generates identification information for identifying one of the transmission devices from information included in the accepted unit data, in accordance with a predetermined generation process. In a case that the generated identification information corresponds to the stored identification information, the transmission device transmits the accepted unit data to the reception device. In a case that the generated identification information does not correspond to the stored identification information, the transmission device sends the accepted unit data to a back stage side.

    摘要: A projection image display device including a display plane for displaying an image, a projection mechanism projecting an image on the display plane, and an imaging mechanism arranged on the same side of the display plane as the projection mechanism for imaging the display plane. The imaging mechanism is arranged at a position where a position symmetric with respect to the display plane of the projection mechanism is out of the range of the field angle of the imaging mechanism. By arranging the imaging mechanism at a position where no direct reflecting light of the light source of the projection mechanism comes, it is possible to prevent generation of a hot spot.
