Abstract: A method for transmitting video data and haptic data between a mobile video acquisition device and a remote computer through a communication network, and a video acquisition device. A server capable of direct communication exists in the communication network. The video data can be presented on a screen of the remote computer for a user to view, and the haptic data can be used to control a motion state of the video acquisition device acting as an avatar of the user. In the present invention, a first channel for transmitting video data and a second channel for transmitting haptic data are established between a computer having access to the Internet and a video acquisition device having access to the Internet by using a server and through a P2P technology. The present invention enables forming of a low-cost long-distance avatar network of multiple users versus multiple avatars, thereby greatly reducing travel of people, and contributing to low carbon environmental protection.

Abstract: A solid state disk (SSD) device includes a random access memory (RAM), a flash memory array, a main power receiving component and a control unit. When a file to be written is not larger than a threshold capacity of the RAM, the file is stored in the RAM; otherwise the file is stored to the flash memory array. When a main power supply stops providing power to the main power receiving component, the control unit moves data stored in the RAM to the flash memory array.

Abstract: A portable electronic device having a pattern identification system includes a substrate, an illumination device, a video camera unit (containing a controllable camera lens), a controller, a programmable identification element and a display unit. The substrate is electrically connected to the illumination device, the video camera unit, the controller, the programmable identification element and the display unit. The illumination device initially projects light on a sample pattern. The controller controls the video camera to magnify an image sufficient for identification at the predetermined position of the sample pattern so as to allow capturing an identifiable image of difference with respect to a programmed feature. The video camera unit captures the identifiable image of the predetermined position of the sample pattern and sends it to the programmable identification element for identifying the sample pattern. The display unit displays an identified result of the sample pattern.
