Abstract: A network including a sensory assembly having a first wire coil coupled to a stationary component, and a spaced apart second wire coil coupled to a movable component. An interstice is formed between the wire coils. The stationary first wire coil is employed in a primary electrical circuit and the movable second wire coil is employed in a second electrical circuit. A magnet flux field permits at least a portion of an electrical current varied as a function of a parameter of the movable component to be transmitted between the electrical circuits.
