| 440009000 | WAVE POWERED PROPELLING MEANS | 9 |
| 20080299843 | Wave power vehicle tethers - A wave-powered water vehicle includes a surface float, a submerged swimmer, and a tether which connects the float and the swimmer, so that the swimmer moves up and down as a result of wave motion. The swimmer includes one or more fins which interact with the water as the swimmer moves up and down, and generate forces which propel the vehicle forward. The vehicle, which need not be manned, can carry communication and control equipment so that it can follow a course directed by signals sent to it, and so that it can record or transmit data from sensors on the vehicle. | 12-04-2008 |
| 20120094556 | Wave power - A wave-powered water vehicle includes a surface float, a submerged swimmer, and a tether which connects the float and the swimmer, so that the swimmer moves up and down as a result of wave motion. The swimmer includes one or more fins which interact with the water as the swimmer moves up and down, and generate forces which propel the vehicle forward. The vehicle, which need not be manned, can carry communication and control equipment so that it can follow a course directed by signals sent to it, and so that it can record or transmit data from sensors on the vehicle. | 04-19-2012 |
| 20120295499 | WAVE-POWERED DEVICE WITH ONE OR MORE TETHERS HAVING ONE OR MORE RIGID SECTIONS - Many of the known wave-powered devices (“WPDs”) comprise (1) a float, (2) a swimmer, and (3) a tether connecting the float and the swimmer. The swimmer generates thrust as the float moves up and down due to surface waves. A WPD is provided with a rigid tether that can be moved from (a) a first position (“adjacent position”) in which at least a part of the tether is adjacent to the float to (b) a second position (“extended position”) in which the tether (i) is extended below the float and (ii) is at least in part substantially rigid. The WPD can if desired be transported, stored, or launched while the tether is in the adjacent position, and the tether can be moved into the extended position after the device has been launched and remain in the extended position while the device is being operated. | 11-22-2012 |
| 20120329345 | Wave-powered autonomous plankton collector - An autonomous submersible vessel employs ambient wave energy to both propel itself and to generate required onboard electrical power. The vessel combines a ballast stabilized stator portion and a wave orbit driven rotor portion. Controlled resistance to their relative rotation occurs only when the horizontal component of wave orbit motion coincides with the desired direction of navigation, so increased hydrodynamic drag at that time acts to pull the vessel forward. The vessel incorporates a means to collect and preserve plankton samples. The vessel design enables alternate operation as an oceanographic glider to also navigate in deep water and in calm seas. | 12-27-2012 |

The vehicle, which need not be manned, can carry communication and control equipment so that it can follow a course directed by signals sent to it, and so that it can record or transmit data from sensors on the vehicle. | 04-25-2013 |

| 20160186716 | Wave-Powered Devices Configured for Nesting - A wave-powered water vehicle includes a) a first component which is a float that travels on or near the water surface; b) a second component which is wave actuated and travels below the first component; and c) a means whereby the first component engages the second component and/or the second component engages the first component; wherein the engagement means provides lateral support of one component for the other, and thereby minimizes lateral movement of one against the other when the components are fitted together. | 06-30-2016 |
