Abstract:
The invention relates to an oscillating blade type windmill includes one or more layer blades moving in opposite directions, cutting off the windward and each layer blade having only one blade. The oscillating blade type windmill according to the present invention comprises a windward angle adjusting apparatus (2) is arranged at the root of blade (1) and shaft (3), an energy and inertia accumulator/releaser (4) of the blade (1) for accumulating energy when the blade (1) moves out of the equilibrium position (the equilibrium position is the position where the blade (1) in the vertical state), and release energy when the blade (1) has the largest angle of inclination relative to the equilibrium position, a variable speed mechanical assembly (5) converts the oscillating motion of the blade (1) into a rotary motion and increases the rotation speed, which is located between the shaft (3) and the motor (6). The windmill further includes a balance weight (7) for balancing weight; of blade (1). The outer shell (8) is located on the ground and automatically rotates blade (1) to windward by a windward angle adjusting apparatus (2), or located on a tower pillar (9), while the windmill using on the sea, lakes or rivers. Wherein the tower pillar (9) is shorter than the blade length (1) many times.

Abstract:
A lighting unit comprises a packaging substrate (10) formed from a semiconductor, a channel (12) formed in the substrate and a discrete light emitting diode arrangement (34) in the channel. A surface region of the channel comprises doped semiconductor layers (20,24) which define a light sensor. The arrangement provides a light sensor (which can be used to determine colour and/or outputflux) for a LED unit, with the light sensor embedded in substrate used for packaging. This provides a low cost integration process and provides good registration between the light sensor and the LED output.

Abstract:
A wireless communication system including receiving and base stations. The receiving station (570) includes a detector (590) that measures a downlink channel correlation matrix for multiple antennas (547) of a base station (500). The detector (590) computes an antenna weight increment vector normal to an antenna weight vector for multiple beams from the multiple antennas (547) of the base station (500). The detector (590) quantizes the antenna weight increment vectors to produce a respective quantized antenna weight increment vector. The receiving station (570) includes a transmitter (580) that sends the quantized antenna weight increment vectors to the base station (500). The base station (500) includes a beamformer selector (565) that receives from the receiving station (570) and re-orthogonalizes the quantized antenna weight increment vector for each of the multiple beams. The base station (500) includes a weight vector modifier (567) that modifies the antenna weight vector for the multiple beams by adding an increment proportional to the respective re-orthogonalized quantized antenna weight increment vector.
