20090116156 | PORTABLE ELECTRONIC DEVICE - In the portable electronic device of the present invention, charging electrodes exposed to the exterior of a casing are electrically connected to a pair of charging terminals mounted upright on the printed circuit board, and a charging terminal (negative electrode, or ground) that is one of the pair of charging terminals is connected to the ground of the printed circuit board. A high-frequency current suppression part is mounted in a series connection on the charging terminal (negative electrode, or ground). The high-frequency current suppression part is a ferrite core, ferrite beads, or another low resistance part. In such a configuration, a secondary electric discharge occurs via the externally exposed charging electrodes and the like when electrostatic discharge noise is applied from the exterior of the portable electronic device and when the ground current of the printed circuit board oscillates due to the discharge electric current that flows at this time, whereby circuit malfunctions are prevented. | 05-07-2009 |

20110108677 | TRAIN CONTROL SYSTEM - A train control system that does not allow running by erroneously receiving a signal of a further preceding train toward the front, nor permits a following train approaching another train beyond an allowable range. The system includes an existing signal system controlling running of a preceding train and a following train based on transmission signals from existing signal transmission devices, an inter-train communications system controlling running of the following train by an inter-train communications transmission signal received from the preceding train, and a train-ID transmission/reception system that detects, using a ground-based train-ID transmission/reception device, passing of the preceding train and also acquires train information of the preceding train, and that then detects passing of the following train and also transmits the train information to the following train, thereby controlling the running of the following train utilizing either one of the existing signal system and the inter-train communications system by changing over therebetween based on the train information. | 05-12-2011 |
20120197466 | OPERATION SUPPORT DEVICE AND AUTOMATIC OPERATION DEVICE - A next station state estimating unit estimates a preceding train position from information about a stop track circuit of a current train and from a signal aspect table. It estimates the time, at which the preceding train exits the next station and brake pattern before the station is canceled, from information about the preceding train position, from information about the occupied track circuit on which the current train is present and related information between track circuits and a station and information about occupied duration of the station, which are retained in a track database, and from a history of the preceding train position retained in a history retaining unit. The time estimated is sent to a driver's cab by a communication unit. | 08-02-2012 |

20100150551 | OPTICAL ADD/DROP MULTIPLEXING SYSTEM, OPTICAL ADD/DROP MULTIPLEXER AND OPTICAL PATHWAY DETOUR PROGRAM - If opening and deleting of arbitrary optical pathways are repeated in a configuration where plural OADM nodes are connected to each other in a ring manner, empty waves in the ring are fragmented, and thus, it is necessary to optimize the optical pathways. When an optical pathway is opened from an OADM node to a different OADM node, transponders capable of connecting two routes to the OADM nodes and of setting different wavelengths for two routes are mounted in a state where there are no empty waves on a part of the route, so that an already-opened optical pathway is detoured to a detour route or a different wavelength in the OADM ring, and continuous empty waves are produced in a section to be opened so as to open a new optical pathway. | 06-17-2010 |
20100260184 | CONTROL APPARATUS - An arithmetic operation portion including a swap arithmetic operation portion which performs an arithmetic operation of swap information concerned with a path route of a packet, and a label processing portion which sets adjustment of a first label based on a result of the arithmetic operation executed by the swap arithmetic operation portion is provided in a control apparatus to thereby attain compatibility between dispersion of packet transfer load and reduction of an error rate in each link. | 10-14-2010 |
20120140775 | NETWORK SYSTEM, MANAGEMENT COMPUTER, AND BANDWIDTH MANAGEMENT METHOD - In a packet transport network, to determine a path route in which a bottleneck does not occur with a small amount of calculation, provided is a network system, including data transfer devices and a management computer, each of the data transfer devices including IFs, in which the management computer is configured to: store remaining bandwidth information on the each of the IFs; select one of bandwidths; judge, based on the remaining bandwidth information and the selected bandwidth, whether or not the each of the IFs is usable; determine a route candidate though which data is transferred, bypassing the each of the IFs which has been judged to be unusable; judge, based on the remaining bandwidth information, whether or not continuity of the IF through which the route candidate passes is possible; and allocate the route candidate, the continuity of which is possible, to a new path. | 06-07-2012 |
20130242804 | PATH CALCULATION METHOD - When a path which is a network communication path is calculated, the amount of path calculation is reduced while satisfying the requirement of the path. The network is logically divided into a plurality of calculation domains, and the divided calculation domains are hierarchically managed, and the path attribute of a path within the calculation domain of a lower hierarchical layer is held as a link attribute of an abstract link of a higher hierarchical layer. | 09-19-2013 |
