It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractThe invention provides a device for the transmission of data between two terminals in which a portion of the body of a living being completes the data transmission circuit. A first terminal is to be worn by a body of a living being, and an interface is provided for coupling of data signals into the body and/or for coupling them out of the body. A second terminal has a touch-sensitive interface by way of which, in the case of a contact by the body wearing the first terminal, it couples data signals coupled into the body out of the body and/or couples data signals into the body. According to the invention, the interface of the first terminal has a first pair of electrodes which are to be arranged at mutually spaced points of the body, and the interface of the second terminal has a second pair of touch-sensitive electrodes which are to be touched by two other mutually spaced points of the body. The data signal to be transmitted is coupled by the transmitting terminal by way of its pair of electrodes as a differential voltage signal into the body, and is coupled by the other terminal as a corresponding differential voltage signal by way of its pair of electrodes out of the body.Other References
