摘要:
A remote activating device remotely activates a device to be activated connected to a first network and a second network. The remote activating device includes a first interface connected to the first network, a second interface connected to the second network, an arrival confirmation processing unit that transmits an arrival attribute confirmation signal to the device to be activated using the first interface and confirms whether or not the arrival attribute confirmation signal has arrived at the device to be activated, and a judging unit that decides the first interface as an activation signal transmitting interface when the arrival attribute confirmation signal has arrived at the device to be activated and decides the second interface as the activation signal transmitting interface when the arrival attribute confirmation signal has not arrived at the device to be activated.

According to an embodiment, a communication apparatus controls controllable nodes. The apparatus includes an acquisition unit and a generation unit. The acquisition unit acquires at least one of a first evaluation value indicating an occurrence frequency of a control request to a target controllable node and a second evaluation value indicating an occurrence frequency of communication error at the target controllable node. The generation unit generates identification information to be assigned to control the target controllable node in a manner such that a bit length of the identification information becomes shorter as at least one of the first evaluation value and the second evaluation value increases.

According to one embodiment, a communication device, which performs communication using a first communication method and a second communication method, converts information to be transmitted into information for forming a pulse that is formed depending on the presence and absence of transmission of a radio wave, according to the first communication method. The communication device decides a suppression time, during which communication with a communication device other than a communication partner is suppressed, on the basis of a result of the conversion. The communication device generates an output signal including the transmission suppression signal, in which the suppression time is set for each first element in the pulse, according to the second communication method, the first element transmitting a radio wave. The communication device transmits a radio wave according to the output signal to the communication partner at timing to transmit a radio wave in the pulse.

According to an embodiment, a data processing apparatus includes an acquiring unit configured to acquire structural information indicating a structure of data; a download control unit configured to download one or more partial data pieces among a plurality of partial data pieces obtained by separating the data on the basis of the structural information, using a separation position of the data as a download start position; a selection receiving unit configured to receive a selection of the separation position of the data; and an output unit configured to output the data from the selected separation position received by the selection receiving unit.
摘要:
A communication apparatus, comprising has a generator which generates format information of a start instruction message, a memory which stores the format information, a communication unit which transmits the format information and receives a start instruction message via a network, and a controller which detects whether or not the received start instruction message corresponds to the format information stored in the memory, and performs start processing and initialization processing based on a content of the start instruction message when the received start instruction message corresponds to the format information.
摘要:
A repeater device that achieves remote activation without fail by increasing the probability of an activation instruction frame reaching a to-be-activated communication device. The repeater device includes an activation signal generation unit that generates an activation signal, which activates a first communication device, when a frame, which is to be transmitted to the first communication device that is one of communication devices connected to a network managed by the repeater device, is received and when the first communication device is not in operation; and an annunciation signal generation unit that generates an annunciation signal, which sets up a non-communication section in which no communication takes place for a certain period of time with a communication device connected to the network. The repeater device sets up a non-communication section using an annunciation signal, and transmits, with the non-communication section set up, an activation signal.

According to one embodiment, a communication device to be connected with an external device via a network includes a connection unit, a variable resistance unit, and a control unit. The connection unit is connected to the network. The variable resistance unit is connected to the connection unit such that a resistance value is detectable from the external device, the resistance value being variable. The control unit changes the resistance value according to an operation state.

According to one embodiment, an electronic apparatus includes one or more first receivers, a transmitter and a change module. The first receivers are configured to receive a command signal which instructs change of a power control state from another electronic apparatus. The transmitter is configured to transmit, to the another electronic apparatus, standby-capability information that includes a communication method adopted by the first receivers and a signal form specifying the command signal. The change module is configured to change the power control state when the first receivers receive the command signal.
