  • Publication number: 20080284607
    Abstract: Provided is a communication apparatus having a human body contact sensing function and a method thereof. The communication apparatus includes: an electrode that comes in contact with the human body; a contact sensor that is connected to the electrode, and instructs the central processing unit to perform an initial operation if contact with the human body is sensed; and a data processing unit that receives a control signal from the central processing unit so as to select whether to transmit or receive data, and performs a transmitting or receiving operation according to the control signal. Accordingly, in order to reduce power consumption when in a stand-by state before human body contact is made in a communication apparatus using a human body as a communication medium, a human body contact sensor is included so as to minimize power consumption of a micro processing unit and a transmitter/receiver circuit until contact occurs.

  • Publication number: 20080287061
    Abstract: The present invention provides a communication apparatus being in directly contact with a human body and using the human body as a transmission channel for data communication. The communication apparatus attached to the human body transmits a signal in the form of a current, receives a signal transmitted from another communication apparatus attached to the human body therethrough, and eliminates noise included in the received signal. In addition, the communication apparatus compares the noise-eliminated signal and a reference signal and recovers an original signal. Further, the communication apparatus generates a base-band signal and transmits the same through the human body.

  • Publication number: 20080259827
    Abstract: A communication system using a frequency determined according to information security protection or a transmission distance of a signal is provided. A local area communication requiring information security protection uses a frequency less than a predetermined frequency, and a local or wide area communication requiring no information security protection uses a frequency greater than predetermined frequency, thereby providing an effective communication environment based on information security protection, a communication distance, and communication characteristics satisfying frequency characteristics of a transmission medium, and accordingly increasing a communication field.
