Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: A computer system capable of showing documents for users to read in a power saving mode is disclosed. The computer system includes a system end and a display end. The system end operates normally in a normal mode, when in a reading mode, the system end converts the data in processing to N pieces of frame data, and then the system end enters a suspend mode. The display end operates continuously in the reading mode. It includes an image buffer connecting to the system end, the image buffer temporarily storing N pieces of the frame data sent by the system end, an input device generating a control signal; a display panel; and an image transmitter connected to the image buffer, the display panel and the input device. The image transmitter displays the frame data on the display panel. When in the reading mode, the image transmitter receives the control signal generated by the input device, and retrieves the specific frame data from the image buffer and sends it to the display panel for displaying.

Abstract: A computer system and a sleep control method thereof are provided. The method includes following steps: when a computer system enters a sleep mode, storing a system parameter into a dynamic random access memory (DRAM) via a central processing unit (CPU); storing the system parameter in the DRAM to a flash memory via a bridge unit; and entering the sleep mode or a power off mode. According to the disclosure, to wake up the computer system is more rapidly and power saving.

Abstract: A control method applied to a computer system in a hybrid sleep mode is provided. The control method includes following steps: entering a first sleep mode of the computer after a system parameter is stored in a memory and a hard drive of the computer system; determining whether the computer system is resumed or not in a predetermined first period in the first sleep mode, if true, resuming the computer system by reading the system parameter from the memory; if false, entering a second sleep mode of the computer system; determining whether the computer is resumed or not in the second sleep mode; if true, resuming the computer system by reading the system parameter from the hard drive; and if false, keeping the computer system in the second sleep mode.

Abstract: A communication device includes a body and a sound receiving device. One end of the sound receiving device is pivotally connected to the body. The sound receiving device includes an omni-directional microphone and a uni-directional microphone. A processor has two modes for starting and operating the omni-directional microphone and the unidirectional microphone, respectively. An angle detecting element is located at the body to measure a rotary angle of the sound receiving device relative to the body, and then the processor switches to one of the two modes according to the rotary angle further to start the omni-directional microphone or the unidirectional microphone.

Abstract: The invention provides a conference presentation system consisting of a portable presentation controller and a main body. The portable presentation controller can be connected to or disconnected from the main body. Since the portable presentation controller itself has a wireless communication function, the conference presentation system of the invention can provide a complex multi-function system having a conference system, a presentation controller, a mobile microphone, a loudspeaker, a music station and so on.
