First Claim
Patent Images
1. A portable device for data communication using a body as a conductor to transmit data to a receiver, the portable device comprising:
- 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 contacted with the body to generate electric potential difference therebetween, so that the signal having the current of predetermined value flows from the transmitting electrode having higher electric potential through the body to the receiver and sinks to the transmitting electrode having lower electric potential.
