An array of fiber optic hydrophones or geophones is formed by winding of optical fiber around a continuous, yet flexible cylindrical core. The cylindrical core contains an elastomer filled with a specified percentage of voided plastic microspheres. The elastomer provides the necessary radial support of the optical fiber, and with the included voided microspheres, provides sufficient radial compliance under acoustic pressure for proper operation of the hydrophone. The cylindrical core can be made in very long sections allowing a plurality of fiber optic hydrophones to be wound onto it using a single optical fiber, with individual hydrophone elements separated by integral reflectors such as Fiber Bragg Gratings (FBSs). The center of the core may include a strength member and a central hollow tube for the passing of additional optical fibers. The aforementioned hydrophone array is then packaged within a protective outer coating or coatings as required for the specified application.

A controllable buoyant system (10) includes a support structure having a sealed hollow enclosure (12) containing a first gas and surrounded by a second gas, either the first gas or the second gas being lighter than ambient air. The hollow enclosure is pre-filled with the first gas via a one-way valve that prevents the first gas escaping and an altitude sensor (14) generates an altitude signal indicative of a height of the support structure. A height transducer (17, 21, 61, 66, 67, 68) coupled to the hollow enclosure is responsive to the altitude signal for varying the buoyancy of the support structure. A controller (15) is coupled to the altitude sensor and to the height transducer and is responsive to the altitude signal and to at least one reference altitude signal for automatically controlling the height transducer in order to maintain the support structure buoyant at the preset altitude.

A water submergence toy is not performed using a screw. It is done by only changing the buoyancy by means of changing the volume. Because of this, the control and surfacing responsiveness becomes very poor. The water submergence toy according to the present invention compresses the air inside a piston when the piston is pushed towards the inside of a cylinder to reduce the volume. This makes the buoyancy smaller. Conversely, when the piston is moved in a direction away from the cylinder, the volume of the air inside the piston becomes larger and the buoyancy increases. In addition, because this type of buoyancy adjustment can be performed manually as well, those who play with a water submergence toy can adjust the buoyancy whenever it is necessary. Because of this, the buoyancy of the water submergence toy can always be maintained in a state adjusted for optimum buoyancy.
