Abstract: An acoustic sensor having one or more segments are electrically coupled to provide a response corresponding to an acoustic pressure applied to the segments. Each segment contains at least one substrate of a desired shape and at least two active members made from a flexible, resilient piezoelectric material, preferably, a polyvinylidene fluoride material. Each substrate includes an enclosed chamber on an outer surface wherein a first active element is within the chamber and a second active element is sealingly placed on the enclosed chamber. The second active element is preferably bonded to a compliant diaphragm sealed to the substrate to provide the sealed chamber. An output response from the first active member is combined with an output response from the second active member to provide for a combined output response having reduced noise. The second active element is covered with a protective layer of a suitable material, preferably a polymer material.

Abstract: An underwater cable arrangement comprises an underwater cable capable of being towed through the water, an external device for mounting on the exterior of the cable, and a coil support device disposed inside the cable for supporting a coil. In some embodiments, the coil support device and the external device have engaging portions which co-act with each other to prevent relative rotation of the coil support device and the external device about the longitudinal axis of the cable. In some embodiments, the underwater cable has a skin and the external device is positioned around the coil support device with the skin of the underwater cable between them. The coil support device and the external device have an interference fit with respect to each other to resist relative movement to the coil support device and the external device in the longitudinal direction of the cable. In some embodiments, the external device and the coil support device are fitted to each other so as to maintain a constant angle between a longitudinal axis of the cable and a longitudinal axis of the external device.

Abstract: A marine seismic cable system for marine surveying comprises an electrical conductor within a tubing for conveying compressed air and electricity between a seismic vessel and equipment such as air guns. The tubing resists elongation caused by water drag forces acting against the tubing exterior surface and provides a protective shield to the enclosed electrical conductor or conductor bundle. This combination uniquely conveys compressed air and electricity while significantly reducing the outside cable diameter to reduce the weight and drag forces acting on the cable system. The combination also permits repair and replacement of the tubing or electrical conductor independent of the other component.
