Abstract: A wave energy conversion device that employs a submerged horizontally-aligned structure provided with a central opening formed in a horizontally extending surface, focuses wave induced water-particle motion, resulting in a flow into and away from the central opening, and a turbine is mounted in the central opening to be driven by this flow of water. Preferably the operation of this device occurs in a structural submerged depth of less than one-half wavelength of waves in the region. In a preferred embodiment, the flow through the central opening is bidirectional, and a self-rectifying turbine is used for unidirectional rotation. In an alternative embodiment, unidirectional check valves are used to direct water flow to a unidirectional turbine. Guide vanes are used to direct the flow inward towards the opening and can also be used to induce swirl in the flow field. When constructed axisymmetrically, the device can generate power from waves coming from any direction.

Abstract: A hydrostatic sensor device and method is provided for detecting changes in elevation in pipes, boreholes, and tunnels below ground. A pressure transducer for sensing differential changes in fluid pressure is provided at one end of an extensible hose or other flexible conduit, while the other end is maintained in an equalizer tank at a reference atmospheric pressure at a given elevation. As one end of the system is moved along a grade, pressure changes at the transducer end relative to the reference pressure at the equalizer end are measured corresponding to elevation changes and are recorded against a distance scale, thus providing an accurate profile of the line surveyed.
