  • Underwater sound generator
    Patent number: 4556963
    Abstract: An underwater sound generator comprising dual opposed pistons in a housing. Dynamic seal assemblies of flexible waterproof material are compressed against the peripheries of the pistons and the housing and form a watertight seal that allows axial motion. Controllers regulate the delivery of pressurized hydraulic fluid to hydraulic actuators which drive the axial motion of the pistons according to a predetermined variation.

  • Fiber optic hydrophone for use as an underwater electroacoustic standard
    Patent number: 4193130
    Abstract: A fiber optic hydrophone for use as an underwater electroacoustic standard. The hydrophone includes a fiber optic acoustic wave detector in one end of the hydrophone which is subjected to incident acoustical waves. A similar fiber optic is in an acoustically isolated compartment where the optic fiber is not affected by the incident acoustical wave. Comparison of light passing through each coil will determine incidence of an acoustical wave on the detector fiber.
