A method and system to capture kinetic energy of the sea waves and convert it to electrical power is presented. The hydrodynamic power of the waves is converted to mechanical power after impacting and moving a special panel. The mechanical power is converted into a controlled-cycle hydraulic power to activate a hydraulic motor, which in turn activates an electrical generator. Electrical power is then measured, controlled and distributed to a power grid or end users.

The invention relates to a method for positioning a substrate relative to a substrate table, is presented. When the substrate is positioned on the substrate table for a first time, a first relative position of the substrate with respect to the substrate table is determined. When the substrate is positioned on the substrate table a second subsequent time, a second relative position of the substrate with respect to the substrate table is determined and the position of the substrate table with respect to the substrate is adjusted based on the first and second relative positions, so that the substrate is positioned with respect to the substrate table substantially equally to the first relative position.

An integrated dual-cavity dual-medium pressure sensing-dynamic indication technology for developing relative pressure measuring tools features that two media with different colors are respectively contained in two elastic cavities which are communicated to each other via a transparent indicating tube in sealed mode. The interface between two media with different colors is used as a dynamic cursor. When an external pressure is applied to one of two elastic cavities, the dynamic cursor will move in the transparent tube to indicate the value of said pressure.

The invention discloses a positive pressure sinking resistance calculation method suitable for a barrel foundation in sandy soil. The situation that a soil squeezing effect in a positive pressure sinking process increases a lateral pressure on an outer side barrel wall is considered; a lateral soil pressure coefficient derived based on a cavity expansion theory is compared with a lateral soil pressure coefficient given in a DNV specification; and a calculation result is closer to an actual condition. The situation that a constraint effect of an inner side wall on a soil body enables a soil plug effect to be formed in a barrel is considered; the generated soil squeezing effect is far greater than that outside the barrel; and compared with a specification method, a method for calculating a soil pressure located in the barrel and derived based on the soil plug effect has the advantage that the calculation result is closer to the actual condition. The situation that soil bodies inside andoutside a barrel body in the positive pressure sinking process present different densities is considered; the barrel wall end resistance inside and outside the barrel is calculated; especially the inner side resistance of the barrel is calculated by adopting a reversely derived frictional angle phi; the method is simple and convenient; and the calculation result is closer to the actual condition.
