The present invention relates to a hydrophone specifically designed for use in high pressure shock wave fields, comprising a thin piezoelectric polymer film secured to a rigid hoop structure, having a centrally located active element and two conducting leads extending from the active element on each side of the film. Under the action of high pressure shock waves, the conductive material which makes up the active area electrode and the conductive leads is slowly removed, altering the hydrophone's sensitivity and eventually rendering it unusable. The present invention provides an improved design for a hydrophone which monitors the loss of electrode and lead integrity due to shock wave action so that the hydrophone may be replaced before it produces invalid readings. The leads on each side of the centrally located active element are electrically switched to measure the resistance between the leads and the central portion. In another embodiment, the film may be a disposable item allowing for rapid replacement once damaged.

An interconnect assembly electrically connecting two circuit members, which include respective arrays of electrical contacts for engagement with the interconnect assembly. The interconnect assembly comprises a plurality of electrical conductors, the plurality of conductors arranged in a spaced arrangement, the spaced arrangement of the conductors substantially corresponding to a spaced arrangement for the respective arrays of electrical contacts to provide contact between the conductors and the contact arrays and a carrier, including a socket and a retainer. The socket includes a plurality of apertures each receiving an upper portion of one of the plurality of conductors and the retainer includes a plurality of apertures each receiving a lower portion of one of the plurality of conductors; and the respective apertures are aligned axially with each other.

An improved store launching device is disclosed wherein the inside of a sdard sonobuoy launch container is modified to accept, and properly dispense, only one smaller and lighter store. A positioning ring is fitted securely onto the inner walls a preselected distance from the discharge end to provide a seat for a perforated obturator. A slotted pressure relief ring, with the edge adjacent the obturator having a biased cut of a predetermined angle therein, is placed adjacent the obturator and the discharge end of the container to surround the store.

A multi-store launcher has each store in a stacked sequence releasably held y a swinging paddle assembly against the ejection force of negator springs. Each paddle assembly carries a burn resistor that is wired to maintain the paddles in a locked position. A pneumatic pulse from the transporting vehicle causes electronic circuitry to make the resistor fail, freeing the paddles to open away from the store and thereby allowing it to be ejected by the negator springs.

An electrical conductor comprises a compressible conductive member and a tubular conductive sleeve, wherein the sleeve includes an internal deformation. The compressible member comprises a tubular lattice of interlaced wires received axially within the sleeve and engaged therein by the internal deformation to retain the compressible member axially within the sleeve.
