  • Patent number: 10953284
    Abstract: A system, methods and apparatus for powered monofin that propels a swimmer through water uses one of two modes of power: 1. An electric-assist mode, in which the propulsor responds to a swimmer's kick by multiplying the work of the swimmer; 2. Inverse mode, in which the propulsor deactivates when the swimmer is working. In this mode, propulsion is inversely related to the work of the swimmer. As the swimmer does more work, power from the monofin is reduced, to a predetermined, average level of propulsion. As the swimmer does less work propulsion increases to the predetermined level.

  • Patent number: 9365276
    Abstract: A watercraft and controller are disclosed. An embodiment includes a controller for the water craft being configured to operate at least one drive propeller of the drive system of the watercraft below a first propeller rotational speed according to a first operating state by operating at least one drive motor, connected to the at least one drive propeller, via a first alternating voltage; and operate the at least one drive propeller above the first propeller rotational speed according to a second operating state by operating the at least one drive motor via a second alternating voltage. In a transition from the first into the second operating state or vice versa, the first internal combustion engine is operated at such a rotational speed that the at least one drive propeller is driven at the first propeller rotational speed, and the first alternating voltage is synchronized with the second alternating voltage.

  • Patent number: 9353725
    Abstract: This disclosure provides improved nautical craft that can travel and navigate on their own. A hybrid vessel is described that converts wave motion to locomotive thrust by mechanical means, and also converts wave motion to electrical power for storage in a battery. The electrical power can then be tapped to provide locomotive power during periods where wave motion is inadequate and during deployment. The electrical power can also be tapped to even out the undulating thrust that is created when locomotion of the vessel is powered by wave motion alone.
