摘要： A method and apparatus using atmospheric pressure and vacuum force to generate electricity performs coordinated operations of normally open (NO) valves and normally closed (NC) valves to repeatedly push water through an upward pipeline to a first vacuum chamber and let the water flow down by gravity to strike the water wheel of a hydraulic power generator installed in a second vacuum chamber to generate electricity. The method and the apparatus is not affected by local climates or geographical locations and may be installed and applied almost anywhere.

摘要： The present invention provides improvement of the operation of a wave energy system by use of a method for predictive control (COM) of the converter machine that maximizes the energy generated by considering the energy conversion efficiency (MOD ENE) and a wave prediction (PRED). Furthermore, the method according to the invention determines the optimal control by minimizing an objective function weighted and discretized by the trapezoidal rule.

摘要： The present invention provides a controller for a pendulum type wave-power generating apparatus. Electric power produced by wave-power generation has been pointed out as being of low efficiency and more expensive than wind-power generation. To overcome the above problems, the present invention uses resonance and impedance matching of the sea waves, thus making it possible to markedly enhance the efficiency of wave-power generation. The present invention does not use a wave-height meter which is generally expensive and controls the generating apparatus in response to variation of the conditions of the sea, thus automatically maintaining the resonance and impedance matching operation, thereby making high-efficiency operation possible. As a result, the cost of the wave-power generation can be reduced, so that the wave-power generation can be widely commercialized.

摘要： An apparatus for facilitating use of instruments in hazardous environments includes a fluid line and a fluid-driven generator. The fluid line includes: an inlet to receive a flow of fluid from a fluid source; a first outlet to convey a first portion of the fluid flow to an instrument as a purge gas; and a second outlet to convey a second portion of the fluid flow. The fluid-driven generator is coupled to the second outlet of the fluid line, and converts fluid-stored energy in the second portion of the fluid flow to electrical energy deliverable to the instrument as the second portion of the fluid flow is received from the second outlet.

摘要： Infinitely variable motion control (IVMC) provides motion control without any requirement for changing gears or use of a clutch. A spur gear transgear, defined as a system having an input, an output and a control, a variable pitch cam having an eccentric inner and outer cam assembly and a driver may be used to form a speed converter. The speed converter is used in various forms to provide an infinitely variable transmission, a differential, embodiments of wind and river turbines and pumps/compressors. In one embodiment, the speed converter drives a direction control assembly (forward, reverse and neutral) and first and second directional control assemblies to provide a vehicle with zero turn radius. A variable torque converter may be used in various embodiments to control torque from a minimum to a maximum by controlling movement of a rotor along a shaft in relation to a stator.
