To prevent tangling of the cable structure, one or more rods constructed from a super-elastic material can be embedded in each of the legs. For example, a first set of superelastic rods can extend from the main leg to the left leg, a second set of superelastic rods can extend from the main leg to the right leg, and a third set of superelastic rods can extend from the left leg to the right leg. In some cases, the super-elastic rods can be incorporated in a conductor bundle used to transfer signals through the cable structure. | 2011-10-06 |
