摘要： A folding wave-energy-harvesting mechanism for an underwater vehicle includes an underwater-vehicle main body and a wave-energy-harvesting-device main body. The wave-energy-harvesting-device main body includes a hydrofoil assembly and a yaw assembly. The first state of the hydrofoil assembly is a folding state, and the second state is an unfolding state. The first state of the yaw assembly is the folding state, and the second state is the unfolding state. The wave-energy-harvesting-device main body further includes a driving assembly and an energy-storage assembly. The driving assembly is configured to switch the hydrofoil assembly and the yaw assembly in the first state and the second state to each other. The energy-storage assembly is configured to store the wave energy harvested by the hydrofoil assembly. When the hydrofoil assembly and the yaw assembly unfold, the hydrofoil assembly increases the efficient area for wave-energy harvesting.

摘要： An apparatus for harvesting energy, such as solar, wind, wave, thermal, and the like, including a solar panel and a duct supporting the solar panel at an operational angle. The duct comprises a bottom shroud and side shrouds, therein forming a large aperture, a small aperture, and an oblique frustum shaped cavity. The oblique frustum shaped cavity is configured to direct a flow of fluid from the large aperture to the small aperture. A flow energy generator, such as a turbine, located at the small aperture is configured to collect flow energy. Temperature differences between the solar panel and the environment may be used to harvest thermal energy with a thermoelectric generator. Fluid flow under the solar panel may decrease the panel temperature and increase the efficiency. Generators may be operated in reverse to lower the solar panel temperature and increase efficiency.

摘要： The present invention relates to a method allowing short-term prediction of the wave motion (force, elevation, . . . ), from a time series of past wave measurements. The prediction method according to the invention is based on the estimation of the variable coefficients of an autoregressive model while allowing multi-step minimization, that is over a horizon of several time steps in the future, of the prediction error.
