The present invention relates to a method and device for monitoring performance of an auxiliary power unit (APU) turbine efficiency of an aircraft. The method comprises: obtaining APU messages at multiple time points within a period; obtaining APU startup parameters including at least a rotation speed at a peak of EGT according to the APU messages; calculating a percentage NPA of the rotation speed when the exhausting gas temperature EGT reaches its peak at the APU startup stage relative to the rotation speed in the APU normal operation; calculating the average of the NPA within the period; and determining which of the stable, decline and failure phases the APU turbine efficiency is in according to the average of the NPA.

A method performed by a camera module () to implement a remote control interface with a mobile device () includes establishing a wireless interface association between the camera module () and the mobile device (), and transmitting, by the camera module () to the mobile device (), a remote control file, whereby the mobile device () builds and displays a remote control view for the camera module (). Real-time video frames are then generated in the camera module () for transmission to the mobile device () and display within the remote control view. The mobile device () can then be used to send camera parameter changes to the camera module () via the wireless interface. The mobile device () remotely monitors and controls the camera module ().

Methods, devices and system for access point facilitated fast handoff are provided. Each access point (AP) in a wireless local area network is provided with a primary interface and a secondary interface wherein the primary interface performs normal communication with user terminals and broadcasts standard beacon frames on its working channel, and the secondary interface broadcasts extended beacon frames on working channels of neighbor APs sequentially. The extended beacon frame includes at least information of BSSID, SSID, working channel and the like of the primary interface of the corresponding AP. The user terminal may receive the standard beacons from the serving AP it is communicating with and the extended beacons from the neighbor APs, and according to the two kinds of beacons, the terminal may calculate the signal quality with the primary interface of the serving AP and the signal qualities with the neighbor APs at the current position. By an algorithm of comparing the signal qualities of the best neighbor AP and the serving AP, the terminal may accurately and quickly determine whether to perform handoff with minimized cost.
