The present invention relates to the utilization of wave energy and its conversion into operating motion of an electrical energy generating system. The system for generation of electrical energy through the conversion of aquatic wave motion includes floating bodies and a constant rotation mechanism, which converts the two-way linear motion of an inflexible transmission shaft or a flexible transmission shafts into one-way rotation of an output shaft of the constant rotation mechanism. This mechanism allows utilization of wave energy in two directions caused by the rise and fall of waves. The output shaft of the constant rotation mechanism is coupled to a force multiplier that is further coupled to a generator which generates electrical energy. Constant rotation mechanism can be driven by inflexible transmission shaft pivotally coupled to the floating bodies at one end, and the other end to an input gear of the constant rotation mechanism. Depending on the height of the wave and the wavelength, various constructions of floating bodies are used. Certain floating bodies are designed for the waves of a smaller amplitude and smaller wavelength, while other floating bodies are designed for bigger amplitude and bigger wavelength.

An energy harnessing device for harnessing wave energy that results in pitch, sway, yaw, surge, roll, and heave movement, wherein the device effectively converts multiaxial translational and rotational motion to unidirectional rotational motion for power transmission.

An electric prosthetic limb is provided with: a below-knee side member; an above-knee side member; a knee joint mechanism that connects the below-knee side member and the above-knee side member in a manner such that an angle formed therebetween is variable; and an extendable device that is capable of extending and contracting to change the angle formed between the below-knee side member and the above-knee side member. The extendable device is provided with a motor and a transmission transmitting power from the motor. The transmission is provided with: a first transmission mechanism that transmits the power from the motor at a first transmission gear ratio; and a second transmission mechanism that transmits the power from the motor at a second transmission gear ratio different from the first transmission gear ratio.

A vehicle transmission using a gearset. Multi-mode clutches selectively couple components of the gearset. The transmission operates in and shifts between a first forward gear and a second forward gear using a change in input rotation. An electric motor coupled to the input may be used to change the input rotation direction.

A combination engine starter and electric power generator device for a work vehicle has an electric machine and a gear set mounted to the electric machine. The gear set is configured to receive rotational input from the electric machine and from the work vehicle engine. The gear set mechanically couples the electric machine and the engine in first and second power flow directions in which in the first power flow direction the gear set effects a first gear ratio and in the second power flow direction the gear set effects a second gear ratio.

A mechanical converter of irregular bi-directional motion into continuous and consistent single direction motion through a system of gears, drive shafts, freewheels, and flywheel. The system works by transforming circular movement, both clockwise and counterclockwise from the input shaft into continuous rotation of an output shaft through the use of a pair of free wheels solidly connected to the input shaft which transfers the alternating motion, depending on the rotation of the input shaft, to two parallel secondary shafts.
