Abstract

A portable device for data communication using a body as a conductor to transmit data to a receiver, the portable device includes a data receiving unit to receive data, a controller unit to control processing of data to be transmitted, a current limiting circuit to limit a current of a signal corresponding to the data to be transmitted to a predetermined value, and transmitting electrodes connected to the current limiting circuit and to contact the body to transmit the signal having the current of predetermined value to the receiver.

Claims

1. A receiver for receiving data communicated using a body as a conductor to transmit the date, the receiver comprising:

receiving electrodes to contact the body to receive a signal corresponding to the data; and

a signal processor to process the signal received through the receiving electrodes, wherein the signal has a current defined to a predetermined value.

2. The receiver of claim 1, wherein:

the receiver is a peripheral device to output a reproduction signal corresponding to video and/or audio data,

the processed signal corresponds to an output obtained from reproducing the video and/or audio data, and

the peripheral device further comprises an output unit to output the signal from the signal processor.

3. The receiver of claim 2, wherein the peripheral device is one of a headset, an earset, an earphone, a visual visor, and a combination thereof.

4. The receiver of claim 2, wherein the output unit comprises at least one of:

a sound outputting unit to output sound corresponding to the signal; and

a display unit to output an image corresponding to the signal.

5. The receiver of claim 4, wherein the signal processor comprises:

an amplifier to amplify the signal received through the receiving electrodes;

a bandwidth pass filter to extract a baseband signal from the amplified signal;

a comparator to convert the baseband signal to a signal of a predetermined voltage; and

a controller unit to divide the converted signal and output the divided signals to the output unit.

6. The receiver of claim 1, wherein:

the data corresponds to an electronic key, and

the receiver further comprises a controller to control access based on the signal received through the receiving electrodes.

7. The receiver of claim 6, wherein the signal processor comprises:

an amplifier to amplify the signal received through the receiving electrodes;

a bandwidth pass filter to convert the amplified signal to a baseband signal;

a comparator to convert the baseband signal to a signal of a predetermined voltage;

a decoding unit to decode the signal of a predetermined voltage; and

a decrypting unit to decrypt the decoded signal to output to the controller.
