Abstract
Abstract A system is disclosed which utilizes a member which oscillates in response to movement of a fluid past it and a means for utilizing the energy generated by the oscillation. In one embodiment the oscillating member is a cable utilizing wind or water as generator or pump. In a second embodiment, the oscillating member is an airfoil having either pitch control or active circulation control.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
83 words
Apparatus for generating energy from a source of fluid in motion comprising: means disposed in said fluid for oscillating in response to the dynamic forces of the motion of the fluid moving past it, said means comprising a flexible cylindrical cable; and means operably coupled to said oscillating means for converting said oscillations into usable energy, said converting means comprising at least a pair of permanent magnets located on either side of the flexible cable and perpendicular to the oscillations of said cable.
Claim 2
Dependent Claim
83 words
Apparatus for generating energy from a source of fluid in motion comprising: means disposed in said fluid for oscillating in response to the dynamic forces of the motion of the fluid moving past it, said means comprising a flexible cylindrical cable; and means operably coupled to said oscillating means for converting said oscillations into usable energy, said converting means comprising at least a pair of permanent magnets located on either side of the flexible cable and perpendicular to the oscillations of said cable.
Claim 3
Dependent Claim
19 words
The apparatus of claim 1 further comprising means for orienting said converting means into alignment with said fluid flow.
Claim 4
Dependent Claim
36 words
The apparatus of claim 2 wherein said means for orienting comprises a streamlining fairing on said magnets, and pivot means for allowing said magnets to turn in response to variations in the direction of fluid flow.
Claim 5
Dependent Claim
104 words
Apparatus for generating energy from a source of fluid in motion comprising: means disposed in said fluid for oscillating in response to the dynamic forces of the motion of the fluid moving past it, said means comprising a flexible cylindrical cable; means operably coupled to said oscillating means for converting said oscillations into usable energy, said converting means including a diaphragm pump operably connected to said oscillating cable means to adjust the tension in said oscillating cable; and a sensor responsive to changes in the velocity of said moving fluid, said sensor connected to said means to adjust the tension of said oscillating cable.
Claim 6
Dependent Claim
104 words
Apparatus for generating energy from a source of fluid in motion comprising: means disposed in said fluid for oscillating in response to the dynamic forces of the motion of the fluid moving past it, said means comprising a flexible cylindrical cable; means operably coupled to said oscillating means for converting said oscillations into usable energy, said converting means including a diaphragm pump operably connected to said oscillating cable means to adjust the tension in said oscillating cable; and a sensor responsive to changes in the velocity of said moving fluid, said sensor connected to said means to adjust the tension of said oscillating cable.
Claim 7
Dependent Claim
14 words
The apparatus of claim 4 wherein said sensor comprises a series of anenometer cups.
Claim 8
Dependent Claim
60 words
The apparatus of claim 4 wherein said sensor includes a vane freely rotatable to maintain an orientation substantially perpendicular to the direction of said moving fluid, said vane being mounted for deflection in response to variations in velocity of said fluid, said vane being operably coupled to said cable to tension the cable in response to deflections of said vane.
Claim 9
Dependent Claim
38 words
The apparatus of claim 6 wherein one end of said cable is mounted on a pivot means to prevent the twisting of said cable when said vane rotates in response to changes in direction of said fluid flow.
