A method and system for automatic zoom adjustment is disclosed. Content is displayed on a display screen for a user. In an auto-zoom mode, a first and a second pictures are acquired. Pre-determined features are detected from the first and second pictures. A first and a second feature distances are computed based on the pre-determined features detected from the first and second pictures, respectively. The first and second feature distances relate to the user's head movement relative to the display screen. An adjustment to the zoom of the content on display is determined based on the difference between the first and the second feature distances.

A power-saving method for an electronic device is provided. The electrical device has a power-saving mode. The method includes detecting a position of the electronic device, and activating the power-saving mode if the detected position is determined to be one of a plurality of pre-determined power-saving positions. A system for performing the method is also provided. The system includes a detection unit for detecting the position of the mobile device, and an operational mode control unit coupled in signal communication with the detection unit. The control unit controls the mobile device to enter one of a power-saving mode and a wake-up mode based on the signals received from the detection unit.

A method to classify the network speed disclosed is utilized to distinguish between an advanced-level user bandwidth and a general-level user bandwidth for users whose devices are connected by the access point. The method includes selecting a bandwidth-distribution rule of the access point, and distributing the total bandwidth supported by the access point according to the selected bandwidth-distribution rule. The bandwidth-distribution rule is selected from a ratio-distribution rule, a highest-band restriction rule, and a lowest-bandwidth restriction rule. The bandwidth distributed to each advanced-level user is larger than the bandwidth distributed to each general-level user.

An over-current alerting circuit used in a hand held device includes a current sensor module, a photo sensor module and an alerting module. The current sensor module is used for sensing a loading current of the hand held device and outputting a photo signal according to the intensity of the loading current. The photo sensor module is used for generating a driving signal when the intensity of the photo signal is higher than a predetermined intensity. The alerting module is used for performing an alerting action after the driving signal is received. In addition, an over-current alerting method is also disclosed herein.

A method for arranging 37 Mandarin Phonetic Symbols (MPS) on a keypad includes arranging the 37 symbols onto 12 keys of the keypad. With this particular arrangement, a maximum number of combinations of MPS generated by pressing three keys on the keypad is reduced from 48 to 16, making input of Chinese characters considerably faster and more convenient.
摘要:
A data protection method. The data protection method is implemented between a server and a mobile communication device capable of wireless communication with the server. The mobile communication device transmits a media download request to the server for downloading of media data. The server receives the media download request and then generates a description file, a protected media file and a license file. The description file comprises download information of the protected media file and the license file. The protected media file comprises a set of encrypted data generated from encrypting the media data. The license file comprises a decryption key for decrypting the encrypted data into the requested media data. The server transmits the description file to the mobile communication device. The mobile communication device receives the description file from the server.
