Abstract: A method for fast activation and playing of multimedia data with a non-fixed data storage media, such as compact disk, is provided. The storage media, pre-installed with an operating system, is used to activate the computer. Then the media player connected to the computer is detected, and a device driver for the detected media player and a corresponding media playing application in the storage media are executed. The process further includes establishing a RAM disk area in the RAM of the computer for the space required by executing the operating system, device driver for the media player, and the media playing application programs.

Abstract: Disclosed is a device and method for dynamically adjusting orientation of a satellite antenna carried in a movable carrier, including a satellite tracking system and an adjusting device. The satellite tracking system includes a position processor that receives a group of positioning signals comprising a current coordinate from a group of GPS satellites and retrieve a program signal comprised a preset coordinate among at least one of program satellites, a comparator comparing the current coordinate with a preset coordinate to generate an deviation, and a microprocessor processing the deviation to issue a control signal that is fed to the adjusting device for changing orientation of the antenna to match with that of the program satellite.

Abstract: Disclosed is a device for dynamically adjusting orientation of a satellite antenna carried in a movable carrier, including a satellite tracking system and an adjusting device. The satellite tracking system includes a position processor that receives an electromagnetic signal from at least one satellite and retrieve from the electromagnetic signal a satellite coordinate, a comparator comparing the satellite coordinate with a pre-set target coordinate to generate an error, and a microprocessor processing the error to issue a control signal that is fed to the adjusting device for changing orientation of the antenna to match with that of the satellite.
