ABSTRACT:
A cable supporting along its length one or more detector units, each comprising a bendable board which is much longer than it is wide and which supports near its center a piezoceramic transducer whose output is responsive to bending of the board, the cable being bared in the vicinity of each transducer and having its conductors connected with the two terminals of the piezoceramic transducer, the board and the portions of the cable immediately adjacent to the board being unitized by a heat shrunk tube which tightly conforms to the board and said cable portions and unifies them so that they become part of the cable with commensurate stiffness.
