Disclosed is a wind turbine generator, which effectively uses wind velocity while generating a minimum of noise. Two blade assemblies, which are subjected to natural wind velocity to rotate for driving a power generator, are coaxially mounted one behind the other. When the front end and rear blade assemblies in this configuration both catch a wind to rotate, the rear blade assembly rotates as it catches not only the wind that comes from the front and is rectified by the front blade assembly, but also a wind that is generated by the front blade assembly, which is rotating. This enables the rear blade assembly to rotate with high efficiency and continuously rotate even when the wind velocity is low.

The present invention relates to mechanical-electrical power conversion systems. The systems comprise one or more electroactive polymers that convert between electrical and mechanical energy. When a voltage is applied to electrodes contacting an electroactive polymer, the polymer deflects. This deflection may be converted into rotation of a power shaft included in a motor. Repeated deflection of the polymer may then produce continuous rotation of the power shaft.

A mirror for facilitating appearance related functions includes a circular ring-shaped frame holding therein back-to-back reflective mirror plates having different magnification factors, e.g. 1× and 5×, each plate having a circular central imaging reflective area and an outer concentric light transmissive window area. Continuously rotatable pivot joints support the frame between opposed arms of a yoke protruding upwardly from a stanchion and base for placement on a table, or an arm and wall bracket for mounting on a wall, enabling the frame to be rotated to interchangeably orient 1× and 5× mirror plates in a forward facing use position. A ring-shaped, printed circuit board with circumferentially spaced apart light emitting diodes (LED's) protruding radially outwards of an outer circumferential edge of the board is located between inner facing surfaces of the mirror plates. Illumination of objects in front of the mirror plates is effected by direct LED rays emitted forwardly through the light transmissive windows, and intensified by indirect LED rays reflected from reflective inner facing surfaces of the mirror plates. Electrical power is supplied to the LED's from a battery power supply in the base of the mirror by electrically conductive pins which protrude radially outwards from opposite sides of the frame, the pins being rotatably supported in electrically conductive cups located in opposed arms of the yoke, the cups being connected to the power supply via wires disposed through the yoke arms and stanchion to the power supply.

To coat a surface of a medical implant such as an organ part or a synthetic prosthesis with a coating of living cells, the implant is inserted and fixed into a receiving container which is at least partially filled with a nutritive liquid medium containing the coating cells in suspension. Then the receiving container is rotated respectively about two distinct rotation axes, whereby preferably the two rotation motions are independently controllable and the two axes are substantially perpendicular to each other. Each of the two rotation motions can be a continuous rotation through 360°, or a stepwise intermittent rotation through successive rotational angle steps.

Apparatus and methodology is provided for directional drilling which avoid the effects of static friction between the drill string and the borehole. The drill string is rotated continuously in one direction during rotating drilling and during steering. During steering, the rotary speed of the drill string is varied within a revolution and substantially similarly for each of a plurality of subsequent revolutions. The drill string is rotated very slowly when oriented at or near the desired orientation to achieve the desired change in direction and then rotated much faster during the balance of each revolution. This angular velocity profile results in drilling at or near a desired orientation for a high percentage of the time it takes for each revolution. Changes in an effective tool-face orientation can be effected by shifting the phase of the velocity profile.
