摘要:
A lighting control system (1) performs a lighting control on slave lamps (30A to 30F) under the control of a master lamp (20A and 20B) communicating with and connected to a management apparatus (10). The master lamp (20A or 20B) includes an adding unit (24a) that adds the slave lamps (30A to 30F) placed under the control of the other master lamp (20A or 20B) to the slave lamps (30A to 30F) under its own control, when the other master lamp (20A or 20B) fails. The master lamp (20A and 20B) includes a lighting control unit (24b) that performs the lighting control on the slave lamps (30A to 30F), based on a command relating to the lighting control, which is received from the management apparatus (10).

A communication device according to an embodiment includes a reception unit (131), a determination unit (132), a generation unit (133), and a transmission unit (134). The reception unit (131) receives a telegram which is transmitted to a node. The determination unit (132) determines whether or not the telegram which is received by the reception unit (131) includes a command related to a communication path. When the determination unit (132) determines that the telegram does not include the command related to the communication path, the generation unit (133) generates a non-pass signal which indicates that the telegram does not pass through a public line. The transmission unit (134) transmits the non-pass signal which is generated by the generation unit (133) to the node.

A radio terminal (901,902) or gateway capable of executing the AV/C protocol on the datalink protocol which starts communications after setting up a logical channel on a radio network (90) is disclosed. The radio terminal (901,902) or gateway transfers data packets according to the stored correspondence information among the protocol identifier (P), the channel identifier that is set up for the radio terminal (901,902) or gateway, and the channel identifier that is set up for a correspondent radio terminal (901,902) or gateway, where the correspondence information is obtained through an exchange of signalling packets containing the channel identifier indicating a logical channel that is set up for transferring the data packets and the protocol identifier (P) indicating the AV control protocol.
摘要:
The disclosed communication node has a function for recognizing one communication node (3110) on the first network as one of constituent elements (3130) in own communication node, and a function for disclosing an own configuration information regarding the constituent elements as recognized above, to another communication node (3110) on the second network. Also, the disclosed communication terminal has a function for disclosing functions in the own communication terminal as Sub Units in an AV/C (Audio/Visual Control) protocol executed on an IEEE 1394 bus, and a function for receiving at least a part of information regarding Sub Units existing in the communication node (3110) on the second network with which it is communicating. Together, these communication node (3110) and communication terminal make it possible to transmit various information transferred on the IEEE 1394 bus, to the radio node (3120) that is connected by the radio interface, and it becomes possible to execute the data communications as if the connection to the IEEE 1394 bus is made by the radio interface.

One embodiment provides a charge/discharge instruction apparatus, including: a charge/discharge instruction unit which instructs a charge/discharge determination apparatus to perform a charge/discharge control of a battery; a charge/discharge information storage unit which stores charge/discharge information for charging/discharging the battery; a control unit which controls an access request to the battery based on the stored charge/discharge information and contents of the charge/discharge control; a generating unit which generates a communication message concerned with the access request controlled by the control unit; and a communication unit which transmits the communication message concerned with the access request to the charge/discharge determination apparatus.
摘要:
In a microprocessor (101) that internally has a microprocessor specific secret key, a key management unit (701) is provided to carry out a key registration for reading out from an external memory a distribution key that is obtained in advance by encrypting the instruction key by using a public key corresponding to the secret key, decrypting the distribution key by using the secret key to obtain the instruction key, and registering the instruction key in correspondence to a specific program identifier for identifying the program into a key table, and to notify a completion of the key registration to the processor core (201) asynchronously by interruption when the key registration is completed.
