Patent ID: 7259482

Claim:
A distance extender for increasing a distance between a first device and a second device in electrical communication with the first device, the distance extender comprising: an electrical cable electrically coupled between the first device and the second device and comprising: a first end; a second end; and a plurality of wires extending between the first end and the second end; a first subsystem electrically coupled to the first end of the electrical cable and to the first device; wherein the first subsystem includes a voltage boost circuit; a second subsystem electrically coupled to the second end of the electrical cable and to the second device; a switch electrically coupled to the second end of the electrical cable and to the second device; a third subsystem including a voltage boost circuit; and a fourth subsystem including a voltage boost circuit; wherein: the first device or the second device generates a data signal and the first device provides an electrical power signal; the plurality of wires includes a first wire; the data signal and the electrical power signal are simultaneously transmitted between the first device and the second device over the first wire; the third subsystem is electrically coupled between the switch and the fourth subsystem; the fourth subsystem is electrically coupled between the third subsystem and the second device; and the switch is electrically coupled between the second subsystem and the third subsystem.
