Patent ID: 8076580

Claim:
A cable for enhancing biopotential measurements, comprising: a feedback core centered within the cable, the feedback core comprising: a first conductive line comprising a central feedback line; a first shield that surrounds the central feedback line; and a first insulator that surrounds the first shield; and a plurality of second conductive lines located radially outside the feedback core; a second shield that surrounds the second conductive lines and the feedback core; a second insulator that surrounds the second shield; a plurality of third conductive lines located radially outside the second insulator; a third shield that surrounds the third conductive line; a third insulator that surrounds the third shield, wherein at least a portion of the third insulator and the third shield are in physical contact; and a sole conductive line disposed between and in physical contact with both the third insulator and the third shield, the sole conductive line comprising a ground line.
