  • Patent number: 8639183
    Abstract: Disclosed herein is a communications system in which a transponder having no radio wave generating source executes data transmission with a reader/writer. The transponder is incorporated in a memory card having a memory with which the reader/writer reads and writes information the memory card being used as loaded in a dedicated slot of a host device. The reader/writer transmits a beacon signal telling a service area at a predetermined time interval. The memory card waits for a beacon signal from the reader/writer within a preset period of time after the host device loaded with the memory card is powered on, executes a connection establishment procedure with the reader/writer upon reception of the signal within the preset period of time and, if the beacon signal has not been received within die preset period of time, enters a sleep state in which at least a wait state of the transponder is stopped.

  • Patent number: 8625587
    Abstract: Network connection of a terminal such as a mobile apparatus can be implemented at a transmission speed higher than that by a radio LAN. A connection method between a terminal and a connection apparatus is configured by replacing a radio LAN with electromechanical coupling, and transmission between the terminal and the connection apparatus is carried out using a baseband as it is without up conversion into a radio frequency band. This eliminates a bottleneck by the throughput of the radio LAN and eliminates the problems of the cost and the power consumption which arise from up conversion of a transmission signal. Further, bridging of data can be carried out by simple code conversion, and since the apparatus configuration is simplified, the cost can be reduced.
