A twinaxial parallel cable includes two conductors arranged parallel to each other, an insulating layer formed around the two conductors by extrusion coating, a shield tape wound around the insulating layer while extending longitudinally, a drain wire arranged inside the shield tape, and an outer coating formed to cover the shield tape. A cross section of the insulating layer perpendicular to a longitudinal direction of the twinaxial parallel cable is formed into an oval shape having a long axis that is 1.7 to 2.2 times a length of a short axis. The insulating layer has a groove in a portion including an intersection of an outline of the insulating layer and a perpendicular bisector of the long axis. The groove is formed to be more than 0.5 times to 0.9 times an outer diameter or a thickness of the drain wire. The drain wire is retained in the groove so that a part of the drain wire protrudes toward the shield tape beyond the insulating layer.

Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.

Systems and methods presented herein provide for elastomeric and flexible cables. In one embodiment, the cables are configured with elastomeric cabling and circuitry. For example, a flexible circuit line (or lines) may be wrapped about an extruded elastomeric substrate (e.g., a polymer). Integrated circuits (e.g., sensors, accelerometers, light emitting diodes, controllers, microprocessors, etc.) may be disposed at various points along the circuit line(s). The cable may then be wrapped with a Polytetrafluoroethylene (PTFE) tape than can be heated to shrink about the cable for protection of the underlying circuitry. Then, the cable may be surrounded with a layer of polymer and extruded to form an elastomeric and flexible cable.

Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.

A twin axial or differential pair cable includes a pair of wires each with an core conductor enclosed in a primary insulator, an insulative inner tape as a secondary insulation spirally wrapping both the pair of wires, a shielding tape longitudinally wrapping the inner tape with an insulative inner layer and a conductive outer layer thereof, a drain wire positioned outside of the shielding tape and at the centerline between the pair of wires, and an insulative outer tape spirally wrapping both the shielding tape and the drain wire. One feature of the invention is to have a seam of the longitudinally wrapping shielding tape located opposite to the drain wire along the centerline in a vertical direction which is perpendicular to the transverse direction defined by two centers of the wires.
