An electronic apparatus and an unlocking method thereof are provided. The electronic apparatus receives an input password. When the input password matches a valid password, the electronic apparatus is unlocked. When the input password does not match the valid password, a protection system is activated. The protection system collects usage information and posts a warning message to a social networking site based on the usage information.

The invention discloses a multi-sink-based dynamic multi-routing source node location privacy protection method in a WSN. The method comprises the following steps: firstly, a phantom source node P<h>is randomly selected; then, a real data packet is segmented into M parts by the phantom source node P<h>, and M forwarding nodes are randomly selected in a candidate region; a shortest routing strategy is adopted to transmit M real data segments to the forwarding nodes; afterwards, the M real data segments are randomly transmitted to corresponding sink nodes along a grid by the forwarding nodes, respectively, multiple paths simultaneously exist in the network at the same moment to protect the source node location privacy; and the sink node generates a new pseudo data packet and continues to transmit along the clockwise loop to interfere with the judgement of an attacker. According to factors of network scale, the location of the source node, the number of attackers and the like, the segmented parts of the data packet are controlled, and multipath is manufactured. According to the method in the invention, the difficulty of cracking the location of the source data packet and the source node is enhanced, a large number of data packets need to be simultaneously intercepted so as to obtain the location of the source node, and the dynamic multipath improves the use ratio of the multi-sink.

The invention relates to a selective querying roll-call method of secondary radar S-mode. Roll-call target sorting part in the selective querying roll-call method comprises combining the roll-call targets and link request information into a target request list G1; obtaining a xth target request Mx in the target request list G1, and calculating a transmission time and a response time of the Mx; calculating the times of remaining N-x targets according to the Mx; sorting the remaining N-x targets from large to small according to receiving times; assigning a value of Rx+1 to the receiving time ofa target appeared firstly and being closest to a receiving time Rx, and assigning a value of Tx+1 to the transmission time thereof; after the assignment is completed, automatically increasing 1 to x,and then judging whether condition A: x<N and Tx>0 is met or not; if the condition A is met, continuing to execute; and if the condition A is not met, completing the roll-call target sorting. According to the selective querying roll-call method of the secondary radar S-mode, the sorting is performed on the targets participating in the roll-call; the global optimization is achieved through the local optimization; the method is fast; more querying targets can be efficiently obtained; the querying efficiency and the time utilization rate are improved.

The high-voltage traversing rotor control method includes the steps that (1), the three-phase current, the three-phase voltage, the rotating speed of the wind driven generator and the swell amplitude of power grid voltage on the rotor side are collected; (2), the collected three-phase current and the three-phase voltage are converted into numerical values in a two-phase synchronous rotating coordinate system; (3), a self-adaptive differential negative feedback value L 'alpha corrected based on the follow-up algorithm is introduced into a current feedback channel on the rotor side; (4), the q-axis voltage component V'rq on the rotor side is obtained through inversion according to the corrected differential negative feedback value L 'alpha; (5), a result of the step (4) is converted into numerical values in the two-phase static coordinate system, and the numerical values are input into a power tube in an inverter module for control. Self-adaptive differential negative feedback values of the doubly-fed wind generator at different rotating speeds and with different swell amplitudes can be optimized, so that the prediction result is more accurate, and the time consumed for processing is shorter.
