Abstract:
PURPOSE: An apparatus of measuring angle of arrival using array antenna, a wireless RF receiver for communication using the same and method of measuring angle of arrival are provided to easily measure the arrival angle of a signal of a millimeter wave band using a delay time at the same time. CONSTITUTION: An arrival angle measure system(100) comprises a reference signal generator(110), a switch(120), a mixer(130), a direction detector(150), an ADC part(140), and a phase shifter(160). The reference signal generator generates the reference signal for synchronizing a sender/receiver. The phase shifter changes the phase of an output signal from an array antenna. The switch selects more than three antenna elements of the array antenna and switches the connection to the antenna element according to the period of the reference signal. The mixer combines the output of the switch and the reference signal ad calculates cross correlation. The direction detector calculates the arrival angle of the signal from the array antenna using the phase difference or a delay time in the combined signal.

PURPOSE: An information sharing method based on a social network service of a portable terminal and portable terminal executing the same are provided to share personal information conveniently. CONSTITUTION: A controller(130) provides a user interface for getting information sharing set up information. The controller controls an information transfer of a user based on the obtained sharing setup information and an information reception of at least one different user. The controller classifies information of one or more different users based on a previously fixed standard. A storage(140) stores user information and information of one or more different users. An input and output unit(150) displays information of the received different user by corresponding to a conrol of the control unit.

PURPOSE: An authentication device using a human body communication, a portable device having an authentication function using the human body communication, and authentication method using the human body communication are provided to supply authentication information through a human body communication even if the bio information is the same by enabling a portable device to compare bio information provided from an authentication device and stored bio information. CONSTITUTION: A biometric information detector(110) detects bio-information of a user. A first controller(120) performs a control for providing the detected bio information to a portable device. The first controller performs authentication process based on authentication information provided from the portable device. A first human body communication unit(130) corresponds to a control of the first controller to transmit the bio information to a human body of the user. The first human body communication unit receives authentication information through a body of the user.

PURPOSE: A human body sound transmission system and a method for transmitting a plurality of signals are provided to transmit plural signals including identical acoustic signal through a human body. CONSTITUTION: A signal synthesizing unit(130) generates a sound high frequency signal by synthesizing an acoustic signal with a high frequency signal. A signal combining unit(140) combines the acoustic high frequency signal and the high frequency signal. A distribution unit(160) receives a signal combined by the signal combining unit, and generates and outputs plural signals having identical size, phase and frequency identical to the input signal. Plural transmitters(171-17N) receive the signals outputted from the distribution unit. The plural transmitters apply the received signal to a human body.
