20090260089	BURGLARPROOF METHOD AND SYSTEM FOR PORTABLE COMPUTER DEVICES - A burglarproof method for portable computer devices is disclosed. When a portable computer device is activated, an IC thereof registers user data to a data server using an internal network device thereof and creates and uploads a hardware data table generated based on detection results by a BIOS to the data server. The hardware data table comprises an IP and a status field representing a use status of the portable computer device. When the status field represents “stolen”, the IC activates a stolen display function to lock a screen of the portable computer device to be incapable of performing any operations by users and performs a corresponding operation.	10-15-2009

20090112499	DEVICE FOR JITTER MEASUREMENT AND METHOD THEREOF - The device for jitter measurement and a method thereof are provided. The device for jitter measure includes a signal retrieving module, a signal amplifying module, an edge detecting module, and a time-to-digital converting module. The signal retrieving module receives a signal-under-test, and retrieves a first pulse signal having a pulse width equal to a period of the signal-under-test. The signal amplifying module amplifies the pulse width of the first pulse signal and thereby generates a second pulse signal. The edge detecting module detects a rising edge and a falling edge of the second pulse signal, and generates a first indication signal and a second indication signal according to the respective detected results. The time-to-digital converting module converts the pulse width of the second pulse signal existed in time domain to a digital signal according to the first indication signal and the second indication signal.	04-30-2009

20090013164	Computer system and method of using power button to switch from one BIOS to another - A computer system, using a power button to switch from one BIOS to another, includes a power button, a detection device and a switch circuit. The power button is electrically coupled to the computer system. The detection device is electrically coupled to the power button, and outputs a switch signal and a boot signal when the power button is continuously pushed for a switch time value, in which the boot signal is used to execute a boot procedure in the computer system. The switch circuit is electrically coupled to the detection device, and switches from a first BIOS to a second BIOS used for the boot procedure, in accordance with the switch signal. A method of using a power button to switch from one BIOS to another is also disclosed.	01-08-2009
20090063834	Auto-Switching Bios System and the Method Thereof - An auto-switching BIOS system and the method thereof, switches to dual BIOS by a hardware control circuit. After the system has been started with the first BIOS to the predetermined period of time and the BIOS_READY signal is detected as disabled, the hardware control circuit switches the system from the first BIOS to the second BIOS and restarts the system with the second BIOS.	03-05-2009
