The system is mounted on or in a sub surface buoy that can move or rotate during measurement and includes a motion sensor measuring six degrees of freedom to account for horizontal velocity and vertical displacement in the subsurface buoy mounted sonar system.

An assembly for harnessing a pendulum motion from fluid wave energy to convert to power. The assembly converts a fluid wave energy into electricity through a pendulum mechanism. The pendulum mechanism makes use of a buoyant sphere that floats in a fluid and absorbs wave energy, such as oscillations, vibrations, and disturbances known in wave energy, while floating in the fluid. A hemispherical pendulum swings in relation to the wave energy. The hemispherical pendulum transmits the swinging motion to an electrical generator for conversion to electricity. The harnessing of wave energy and swinging of the hemispherical pendulum is controlled through various components that balance and stabilize the assembly. The sphere comprises components to help control the irregularities from wave energy on the hemispherical pendulum through a directional guidance member, a velocity regulation member, and a stabilization member. A transmission cable transmits the electricity to a control center on shore.

The invention relates to the technical field of purifying equipment, in particular to a pressurizing mechanism of a water purifying device and the water purifying device. The pressurizing mechanism ofthe water purifying device provided by the invention comprises a fluid pressurizing component and a caching component which communicate with each other, wherein the fluid pressurizing component is used for pressurizing a fluid; the caching component is used for caching the pressurized fluid in the fluid pressurizing component; a fluid discharging opening is formed in the caching component and isused for realizing the discharging of the fluid from the component. The fluctuation of the discharged fluid can be effectively reduced by discharging the fluid which is pressurized in the fluid pressurizing component after the pressurized fluid is cached in the caching component, so that the problem of great fluctuation of the fluid which flows out from the pressurizing mechanism can be solved. According to the water purifying device provided by the invention, through application of the pressurizing mechanism of the water purifying device, the fluctuation of the fluid which flows out from thepressurizing mechanism can be reduced, noises, vibration or abnormal sound produced when the fluid flows into a filtering element are reduced, and the using experience of a user is improved.

The invention provides a megasonic cleaning head and a megasonic cleaning system provided with the same. The cleaning head comprises a transducer and a resonator which is used for transmitting energy from the transducer. The resonator comprises an upper surface and a lower surface and the upper surface is coupled to the transducer; and a vacuum hole array which not penetrates through the upper surface and the lower surface are arranged in the resonator. the megasonic cleaning head provided by the invention has the beneficial effect that, because of the adoption of the resonator internally provided with a non-through vacuum hole array in cylindrical shape or other geometrical shapes, the non-homogeneity of vibration waves is eliminated through compensating consumption effect achieved when megasonic waves are reflected many times in the resonator, so that the uniform distribution of megasonic energy is realized. When ultrapure water or chemical liquid is sprayed in a semiconductor, impurities on the semiconductor are washed off through uniform fluid waves which are generated by the megasonic wave and then the impurities are brought away by the flowing of the liquid, so that the semiconductor is cleaned and the damages to the semiconductor are smaller.
