  • Patent number: 9264105
    Abstract: A communication device includes a sensor, an antenna, and a notification component. The sensor is configured to detect magnetic field strength. The antenna is configured to generate a magnetic field. The antenna is further configured to communicate with a wireless device that is configured to generate a magnetic field during communication. The notification component is configured to notify a positional offset between the antenna and the wireless device based on output signal indicative of the magnetic field strength. The sensor is arranged with respect to the antenna such that an effect of the magnetic field generated by the antenna on the output signal is suppressed.

  • Patent number: 8495128
    Abstract: A plurality of servers each transmit data of an initial screen to be displayed on a display screen of radio equipment at a predetermined time interval. The radio equipment is in a reception waiting mode until it is connected to any one of the servers, and is performing channel scanning. Once the data of the initial screen transmitted from any one of the servers is received by the radio equipment, the radio equipment displays the initial screen on the display screen based on the received data. When an operation of a connection instruction is performed on the initial screen, the radio equipment is connected to the server corresponding to the initial screen.
