Patent ID: 8130118

Claim:
A system comprising: a first tubular tool string component, said first tubular string component having a first end, said first end having a first shoulder and a first coupling means, said first shoulder having a first groove formed therein; a second tubular string component, said second tubular string component having a second end, said second end having a second shoulder and a coupling means, said second shoulder having a second groove formed therein, and said second tubular string component being coupled to said first tubular string component through said coupling means, thereby positioning said second shoulder proximate said first shoulder; a first inductive coil disposed within said first groove, said first inductive coil having a first electrical conductor having a first number of turns; and a second inductive coil disposed within said second groove, said second inductive coil having a second electrical conductor having a second number of turns, said second number of turns being greater than said first number of turns, and said second inductive coil being in magnetic communication with said first inductive coil a third inductive coil in electrical communication with said first inductive coil, said third inductive coil disposed proximate said first end of said first tubular string component, said third inductive coil having a third electrical conductor having a third number of turns; a fourth inductive coil in electrical communication with said second inductive coil, said fourth inductive coil disposed proximate said second end of said second tubular string component, said fourth inductive coil having a fourth electrical conductor having a fourth number of turns, said fourth inductive coil being in magnetic communication with said third inductive coil.
