摘要:
In accordance with the present invention, a plurality of routers in more than one network based on different protocols can be integrally managed. The management system of the present invention is capable of integrally managing a plurality of routers in a network based on IPv6 from another network based on IPv4, wherein a relay server receives the identification data from a router, and transmits it to a LAN server. The LAN server uses the received identification data, and pushes the configuration data prepared in advance for the accessing router into the router. The relay server, which has a converting function between IPv4 and IPv6, manages the network on the routers side by IPv6 while it manages the network on the LAN server's side by IPv4.
摘要:
An average power indicating channel characteristics is outputted from a reference value calculation unit as a reference value. An interference level corresponding to the degree of influence by frequency selective interference is outputted from an interference detection unit. A reliability determination unit determines a carrier that has been subjected to interference on the basis of the reference value and the interference level, to decide a reliability level. An error correction unit performs error correction of a demodulation signal on the basis of the reliability level.

A reception apparatus for receiving an OFDM signal having a plurality of pilot carriers that transmit predetermined pilot signals at predetermined symbols. The reception apparatus transforms the received OFDM signal to a frequency-domain OFDM signal, determines channel responses corresponding to the transmitted pilot signals for each of the pilot carriers among a plurality of carriers constituting the frequency-domain OFDM signal, determines, based on channel responses corresponding to first, second and third pilot signals transmitted sequentially in a same carrier, a channel response at a symbol between the second pilot signal and the third pilot signal, compensates a waveform distortion in the frequency-domain OFDM signal according to the channel response at the symbol between the second pilot signal and the third pilot signal and outputs the results.

摘要:
A hoisting apparatus with a horizontal stabilizing means for a load holder is provided. This apparatus comprises a base secured to a ceiling, a load holder, to which a load is detachably attached, a pair of cables extending between the base and the load holder, and a drive means mounted on the base, which is operative to take in or let out the cables from the base. The horizontal stabilizing means includes a shaft horizontally supported in the load holder to be freely rotatable, around which the cables are wound in opposite winding directions to each other. The horizontal stabilizing means is operative to correct an inclination of the load holder in a horizontal position by unwinding a required length of one of the cables from the shaft and at the same time winding the same length of the other one around the shaft.

A package tray for a vehicle in which the motion of the sideboards is improved and the raising of the main board and slide board is operated by the same driving source which moves the sideboards. A first output shaft is intermittently operated to move the sideboards from a position adjacent a side of the slide board to a position under the slide board and the main board.

A luggage panel opening and closing device positionable in a front open condition and a rear open condition to permit access to the luggage space includes a support bracket positioned between a vehicle body and a luggage panel, a link member between the luggage panel and the support bracket, and a multiple link mechanism between the support bracket and the vehicle body.
摘要:
SP signals to be transmitted from a first transmitting antenna are arranged in the same pattern as SP signals to be transmitted from a second transmitting antenna. The SP signals to be transmitted from the second transmitting antenna in one symbol are generated, such that the polarity of the SP signals are alternately inverted and non-inverted with respect to the SP signals to be transmitted from the first transmitting antenna in the same symbol. Thus, in the direction that the symbol number is incremented by 1 and the carrier number is incremented by 3, the polarity of SP signals transmitted from the second transmitting antenna are all inverted or non-inverted with respect to the polarity of corresponding SP signals transmitted from the first transmitting antenna.
摘要:
A transmitter modulates for each symbol period a plurality of carriers that include a carrier group that is consisted of a plurality of prescribed carriers, and repeatedly transmits control information in cycles by using the carrier group. The transmitter transmits multiple-bit binary data of the control information in each symbol period, thereby transmitting the control information once in each of the cycles that includes at least one symbol period. The transmitter controls the transmission unit to switch, within the carrier group, for each of the cycles, carriers of bits of the control information, according to a prescribed rule.

SP signals to be transmitted from a first transmitting antenna 11 are arranged in the same pattern as SP signals to be transmitted from a second transmitting antenna 12. The SP signals to be transmitted from the second transmitting antenna 12 in one symbol are generated, such that the polarity of the SP signals are alternately inverted and non-inverted with respect to the SP signals to be transmitted from the first transmitting antenna 11 in the same symbol. Thus, in the direction that the symbol number is incremented by 1 and the carrier number is incremented by 3, the polarity of SP signals transmitted from the second transmitting antenna 12 are all inverted or non-inverted with respect to the polarity of corresponding SP signals transmitted from the first transmitting antenna 11.
