Abstract: The personal computer adaptor device is provided with an adaptor-side signal input terminal connectable to a headphone terminal for audio signals of a personal computer, a control signal output terminal connectable to a microphone terminal of the personal computer, a plug unit connectable to an outlet jack of a power line, a digital converter for converting audio signals inputted from the adaptor-side signal input terminal into digital signals, an adaptor-side power line communication transmitting unit for transmitting audio signals via the power line connected to a plug unit, an adaptor-side power line communication receiving unit for receiving control signals of the personal computer transmitted from the output device connected to the power line via the power line connected to the plug unit, and an analog converter for converting control signals into analog signals and outputting them from the control signal output terminal.

Abstract: A wireless temperature sensor that is attached to the patient's skin in order to measure the patient's temperature, thereby adopting a patient moving in the facilities as a measuring object. The wireless sensor is a wireless temperature sensor?having a function of wirelessly transmitting measured data through a chip antenna, and the chip antenna has a length of a shortening coefficient so as to be received in a container, and is received in the container. In addition, the invention provides a wireless interface device in which a wireless communication function is provided to a wireless communication card having a low carrier frequency, a small antenna, an enlarged communication distance, and low power consumption. Furthermore, the invention provides a wireless sensor system in which the sensor notifies a patient of surrounding environment information by a wireless communication device whereby a base station collects the environment information from a plurality of sensors.

Abstract: A mobile unit database server and a mobile radio router are provided to enable to process data as well as a plurality of communication terminals in one grouping without using telephone lines. The mobile unit database server is used in a communication system having at least one radio server connected to a network, and a radio base station communicating using radio signals with the mobile radio router connected to the radio server and to more than one terminal. The mobile unit database server is provided with: a mobile unit information database storing mobile unit information that associates identifiers and/or FQDNs and/or mobile FQDN of said mobile radio router with the identifiers and/or FQDN and/or IP address of the terminal connected to the mobile radio router, and are stored as mobile unit information; and mobile unit managing devices for renewing mobile unit information in response to a request to register mobile unit information sent from the radio server.
