Abstract: A blade speed control system is disclosed and applied to a generator and a blade. A control method of the blade speed control system includes: setting the blade speed control system to a first mode; detecting a voltage value and a current value of the generator by a processing unit; generating a modulated signal according to the voltage value and the current value by the processing unit; switching the blade speed control system to a second mode by the processing unit; and adjusting the current value according to the modulated signal by a control unit.

Abstract: A method and system for blocking some specific function of a P2P application in the network is disclosed. The method includes the steps of: (a) continually monitoring a plurality of network connections established by a plurality of clients; (b) collecting the packets sent by a P2P application from one of the plurality of clients when one of the plurality of clients establishes the network connection; (c) comparing the lengths of the collected packets; (d) determining a specific function to be performed by the P2P application based on the result of comparison; and (e) blocking the determined specific function of the P2P application.
