    摘要： A radiation reducing apparatus for a wireless communication device includes a sensing module, a control module, and a radiation reducing module. The sensing module senses radiation intensity of the wireless communication device and generates a signal corresponding to the sensed radiation intensity. The control module compares the sensed radiation with a preset radiation intensity threshold. The radiation reducing module is activated by the control module to reduce the radiation of the wireless communication device when the sensed radiation intensity reaches the radiation intensity threshold.

    摘要： The invention discloses a pitch control system for a wind turbine and a method, comprising a main controller, a secondary controller, a motor and a pitch gearbox, wherein the main controller is connected with a plurality of the secondary controllers through a communication bus; each blade corresponds to one controller and at least two motors, and one pitch gearbox is driven by each motor. The main controller is used for calculating a pitch expected value according to wind speed as well as power and rotation speed of a generator; and the motor is driven by the secondary controller according to the pitch expected value, so as to drive the pitch gearbox and hence drive the blades to vary a pitch angle.
