Abstract: A submergible wave energy converter and method for using the same are described. In one embodiment, the wave energy converter may be used for deep water operations. In one embodiment, the submergible wave energy converter is an autonomous unmanned vehicle that enables remote ocean power generation. In one embodiment, the wave energy converter apparatus comprises an absorber having a body with an upper surface and a bottom surface and at least one power take-off (PTO) unit coupled to the absorber and configured to displace movement of the absorber body relative to a reference, where the power take-off unit is operable to perform motion energy conversion based on displacement of the absorber body relative to the reference in response to wave excitation, and where the power take-off unit is operable to return the absorber body from a displaced position to a predefined equilibrium position and to provide a force acting on the absorber body for energy extraction.

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.

Abstract: A novelty bank assembly and its associated method of operation. The novelty bank assembly includes a bank structure that defines an internal money compartment. An animated character is also provided that is connected to the bank structure. Within the novelty bank assembly is a microprocessor that senses when money is added to or removed from the money compartment. The microprocessor also controls movements of the animated character and broadcasts selected audible phrases. The microprocessor moves the animated character and broadcasts selected phrases depending upon the condition of the novelty bank assembly and the action of a person using the novelty bank assembly.

Abstract: A boat having an external float pivotally fixed to the boat. Through linkage, the motion of the float relative to the boat resulting from wave motion drives a dual cylinder pump. The pump admits water from the body of water in which the boat is suspended and pressurizes that water for direction aft as a means for propulsion.
