Windraider is a process and a machine for converting wind energy into electricity. The Windraider process is a previously undiscovered highly efficient process for converting kinetic wind energy into oscillating rotating mechanical energy. The Windraider machine provides a unusually robust and stable platform for effecting the Windraider process, and a series of mechanisms for improving its range of applicability and for efficiently converting its resulting oscillating rotating mechanical energy into electrical energy.

Provided is a power generation device using magnetic force, the power generation device comprising: a plurality of tunnel-type bodies having unilateral open passages and arranged and fixed at the same intervals on a revolutional orbit, wherein the respective tunnel-type bodies are provided with a plurality of permanent magnets between inner magnetic bodies and outer magnetic bodies, and permanent magnets and the outer magnetic bodies are attached to the outer surface of the inner magnetic bodies such that the permanent magnets facing the inner and outer magnetic bodies can have opposite polarities, thereby forming magnetic fields in inner body spaces; and magnetic border membranes having opposite magnetic poles on the inner and outer sides thereof and formed on entrance sides and exit sides of the tunnel-type bodies.

An electrically-adjustable tool holder precisely movable in a straight line within a magnetic field under electrical stimulation includes a handle body, a connecting member, and a driving member. The connecting member has a first end securely coupled to an end of the handle body, a second end opposite to the first end, and defines a through hole passing through the first end and the second end. The driving member includes a magnet securely received in the through hole, and an electrical electric coil movably received in the magnet. The electric coil is configured to be securely coupled to the tool, and moves the tool up or down along the central axis of the handle body.

A vibration actuator includes a movable body provided with one of a coil and a magnet that is disposed radially inward of the coil with a gap formed therebetween, a fixing body provided with the other of the coil and the magnet and a shaft portion, and an elastic support portion, the movable body vibrating in a vibration direction by means of cooperation between the coil supplied with power and the magnet. The movable body is provided with a through-hole into which the shaft portion is inserted with a gap formed between the through-hole and an outer peripheral surface of the shaft portion and the elastic support portion supports the movable body such that the movable body does not come into contact with the shaft portion at a time when the movable body does not vibrate and at a time when the movable body vibrates.

A pumping system utilizes a linear actuator to move a shaft attached to two pistons within cylinders to pump a working fluid. A housing is designed with coolant passageways and one-way valves such that movement of the shaft also pumps coolant past cooling fins and over a motor. The shaft is formed of several sections joined by couplers which slide within a bore of the housing. The couplers have a non-round shape and the bore has a complimentary non-round cross section such that rotation of the shaft is prevented.

An optical module and a projector including the optical module are provided. The optical module includes a base, a first frame body disposed in the base, an optical element disposed in the first frame body, and at least one driving assembly disposed between the base and the first frame body. The first frame body is configured to swing relative to the base through a magnetic force generated by the at least one driving assembly, and each of the at least one driving assembly includes a coil and a magnetic structure that is separated from the coil and includes a magnetic permeable plate, a separation medium, and a magnet element. The separation medium is located on one side of the magnetic permeable plate facing the coil. The magnet element is disposed on the side of the magnetic permeable plate facing the coil and is separated by the separation medium.
