Abstract:
A system for identifying the ends of a single selected conduit, comprising:a transmitter for producing an electrical signal output; an output transducer communicatingly connected to said transmitter for converting the electrical signal output to a sonic signal and for emitting the sonic signal therefrom; means for directing emission of the sonic signal into one of the ends of the conduit for transmission of the sonic signal through the conduit, said means for directing including an output wand interconnecting said transmitter and said output transducer, said wand having a degree of flexability sufficient to allow said output transducer to be movable relative to said transmitter and to allow said output wand to be bent into desired shapes and orientations to facilitate proper positioning of said output transducer at the one of the ends, said output wand having a degree of structural strength sufficient to allow said output wand to retain any of various of said desired shapes and orientations into which the wand is bent in order to hold said output transducer in a desired position at the one of the ends; an input transducer for receiving the sonic signal and converting the sonic signal to an electrical signal input; means for positioning said input transducer proximal to an opposite one of the ends of the conduit; a receiver communicatingly connected to said input transducer for receiving the electrical signal input and distinguishing the electrical signal input from noise and producing a receiver output in response thereto; an indicator communicatingly connected to said receiver and responsive to the electrical signal input for indicating receipt thereof for determining whether there is signal transmission between the one of the ends and the opposite one of the ends and thereby identify whether the one of the ends and the opposite one of the ends are end portions of the single selected conduit.
