Abstract: There is provided a storage cell state notifying system capable of properly determining a frequency to notify a state of a storage cell being monitored. The storage cell state notifying system includes a storage cell state measuring means 81, a frequency determining means 82, and a storage cell state notifying means 83. The storage cell state measuring means 81 measures a state of the storage cell. The frequency determining means 82 determines a frequency to notify the measurement result depending on the amount of change in the measured state. The storage cell state notifying means 83 notifies information indicating the state of the storage cell at the frequency determined by the frequency determining means 82.

Abstract: A mobile terminal prompts a user to make a voice message upon detection of an abnormally interrupted call, and records the message. Then, the mobile terminal converts the recorded voice data and a telephone number of a communication partner's terminal into a format suitable for data communication. Next, the mobile terminal transmits the converted data to a mobile data communication relay base station. The mobile data communication relay base station forwards the converted data to a data communication network storage device via a data communication network. A stored message transmitter retrieves the telephone number of the communication partner's terminal from the data communication network storage device and calls the communication partner's terminal via a fixed telephone network.

Abstract: A mobile terminal transmits an N-th authentication key to an authentication server when the mobile terminal has moved from a coverage area under a certain radio access point to a coverage area under another radio access point. The N-th authentication key is generated by applying a hash function to a random number a number of times one smaller than an (N?1)th authentication key which was transmitted when the mobile terminal moved to the coverage area under the certain radio access point. Upon receipt of the N-th authentication key from the mobile terminal, the authentication server applies the hash function once to the N-th authentication key, and compares the result with the (N?1)th authentication key. Then, the authentication server determines that the authentication is successful when there is a match between both keys.

Abstract: An ECU of a night vision system stores small obtained images of provisional targets as six templates depending on the distance from infrared cameras, and selects one of the templates depending on the distance up to an actual object. Using the selected template, the ECU performs template matching on images obtained by the infrared cameras, and calculates coordinates of the inspection target. The ECU compares the calculated coordinates of the inspection target and stored reference coordinates with each other, and determines mounted angles of the infrared cameras.

Abstract: A traffic rerouting method for rerouting traffic to be passed to a receiving end from an old path to a new path includes rerouting the traffic by reducing the amount of traffic passing through the old route while at the same time increasing the amount of traffic passing through the new path.

Abstract: A communication-quality monitoring system includes a receiving unit for receiving packets to detect packets of a traffic, a frequency-distribution calculator for calculating frequency distribution of the arrival times of the received packets, and a degradation detection unit for detecting degradation of communication quality in the network by comparing statistic parameters of the peak in the frequency distribution against thresholds of the parameters. The parameters include a dispersion, standard deviation, half-power breadth and peak power of the peak in the distribution diagram.

Abstract: A probe device registers a passage history of the probe device itself with a packet, transfers the packet with which the passage history is registered and sends the same to a loss point judging device through a plurality of probe devices. The loss point judging device monitors at least one of a passing path of the packet, an occurrence point at which a packet loss occurs, and a change in a transfer path of the packet, based on the passage history of the packet included in the packet received through the plurality of probe devices.

Abstract: A method for detecting an unauthorized or illicit traffic through a network comprises the steps of storing the expected values of a behavior for each type of the traffic in advance, separating individual traffics when performing communications through the network, measuring the behavior of the individually separated traffic, comparing the measured behavior with the expected values of the behavior, and determining the unauthorized or illicit traffic from the measured result.

Abstract: The content distribution system of the invention changes over the content distribution destination between terminals which have different content receiving formats. The terminals comprise means for requesting, while viewing content from a broadcasting station, changeover of distribution of this content to another terminal. The broadcasting station comprises means for changing over the content distribution destination on the basis of the aforesaid request. The content distribution system of the invention also comprises means for deciding on the distribution format of content in accordance with the type of aforesaid other terminal, which corresponds to the destination to which content distribution is to be changed over to by the changeover means.

Abstract: A wireless communication system has a packet switch, a position management table, and a position detector. Based on the fact that a position registration packet including the MAC address of a mobile terminal is received from a certain port, the position detector recognizes that the mobile terminal is present in the service area of a wireless base station connected to the port. Then, the position detector registers the MAC address of the mobile terminal and the port number of the port in the position management table 12. When the packet switch receives a data packet, the packet switch extracts the MAC address of a destination from the data packet, and searches the position management table based on the extracted MAC address. If a port number is hit in the searching of the position management table, then the packet switch recognizes the hit port number as an output destination, and transfers the data packet to the port represented by the port number.
