A water powered unit design produces clean electricity, moves and lifts water, generates compressed air and can be adapted to several types of mechanical systems to produce energy. Also described are micromechanical components. The wave spring and the snap ring are rotatable with respect to each other. Also provided is a method of treatment andor prevention of one or more diseases or malfunctions of the eye, comprising implanting one, two, three or more devices of the invention into an eye of a patient. Based on the component values of a set of computer components, decisions can be made as to what portion of computer operations should be reassigned to enable computer operations to be executed in a more balanced manner by the set of computer components. The technique includes estimating a noise component in a set of multicomponent seismic data representing a recorded wavefield from the relationship at the free surface of an upgoing component and a downgoing component decomposed from the recorded wavefield; and removing the estimated noise component from the seismic data.
