摘要:
A terminal apparatus includes: a transmission unit transmitting, to a master device, a first registration request indicating a request for registration as a new control target terminal; a reception unit receiving registration request acknowledgement information transmitted from the master device in response to reception of the first registration request; a notification unit notifying the outside of the terminal apparatus of notification information included in the registration request acknowledgement information and indicating the master device has received the first registration request; a detection unit detecting another terminal apparatus that is to transmit, to a master device, a second registration request indicating a request for registration as a new control target terminal; and a registration control unit controlling, when the detection unit detects the other terminal apparatus, at least a time when the first registration request is transmitted.
摘要:
An LC composite component has a unique structure that makes it easy to set frequency characteristics while reducing a circuit area and the number of layers. The LC composite component includes a laminated body including a plurality of dielectric layers. The laminated body is produced by forming input and output electrodes and an LC resonant circuit therein. The LC composite component includes a capacitor, which includes an elongated electrode portion having an elongated shape. The elongated electrode portion faces a flat electrode portion having a flat shape, with one of the dielectric layers interposed therebetween. At the same time, the elongated electrode portion constitutes an open stub that is open at a tip end.

A mobile communication device (98b) includes: an appliance information obtainment unit (98n) that obtains appliance information (98n1) by proximity wireless communication (98c1) with an appliance (98a) installed in a home (99), the appliance information specifying the appliance (98a); a position information obtainment unit (98j) that obtains position information (98j1) of the mobile communication device when the proximity wireless communication (98c1) is performed; and a transmission unit (98o) that transmits transmission information (98o1) to a server (98c) in the case where the proximity wireless communication (98c1) is performed, the transmission information including the appliance information (98n1) and the position information (98j1).
摘要:
The present invention can prevent a fuzzy image, which is caused due to insufficient bandwidth when the bandwidth necessary for transmitting a content cannot be secured, to be displayed on a display device. When a relay apparatus (100) receives, from a DNS server, a DNS response packet regarding a domain name of a server which transmits a content, a condition judging section (210) in the relay apparatus (100) judges whether a required bandwidth for the content corresponding to the domain name can be secured in a communication path connecting to another relay apparatus (100). If the condition judging section (210) judges that the required bandwidth cannot be secured, a DNS modifying section (250) in the relay apparatus (100) rewrites a reply IP address included in the DNS response packet to an IP address of the relay apparatus (100).
摘要:
A communication device (8802), which can simplify various setting processes, transmits, to a server (8803) via a network, external device information received from an external device (8801) by using proximity wireless communication. The communication device (8802) includes: an antenna (8808) for the proximity wireless communication with the external device (8801); a proximity wireless communication unit (8809) communicating with the external device (8801) via the antenna (8808) to receive the external device information from the external device (8801); an external device storage unit (8813) storing the external device information received by the proximity wireless communication unit (8809); a registration information generation unit (8812) generating registration information to be registered in a database in the server (8803) based on (a) the external device information stored in the external device storage unit (8813) and (b) communication device information including communication device identification information for identifying the communication device (8802); and a server communication unit (8830) transmitting registration information to the server (8803) via the network.
摘要:
Provided is a communication terminal that is capable of securing a route having the finest state while suppressing a bandwidth that is consume by a transmission of a control packet at a low level, when applied in an ad-hoc network which uses an electrical power line. The communication terminal included in the ad-hoc network acquires a plurality of route candidates at the beginning of a data transmission by conducting a broadcast transmission of a route creation packet, and acquires a route having the finest state by conducting an unicast transmission of a route estimation packet to each of the route candidates in each predetermined period.
摘要:
Provided is a communication terminal device that reduces, in a network using a power line, the percentage of bands consumed for transmission of control packets in the bands consumed for all the communication, so as to ensure transmission of data intended to be transmitted. A PLC terminal F701 connected to the network of power line communication transmits, when having determined that the terminal does not receive from the network a beacon for a predetermined period of time, a beacon request packet to the network, using a modulation method having the lowest communication speed among the modulation methods that can be used in the network.
