Abstract: A wireless power transmission device includes a transmission device and a control device. The control device generates a driving signal to the transmission device in a first soft-start period, so as to drive the transmission device. The control device measures an energy message generated by the transmission device to generate a measurement result in a measurement period, and calculates a signal parameter according to the measurement result. The control device accordingly generates a carrier signal according to the signal parameter obtained by the measurement period in a second soft-start period. In a transmission period, the carrier signal is transmitted to the wireless power-receiving device through the transmission device. The energy message is generated by the transmission device in response to a distance between the transmission device and the wireless power-receiving device.

Abstract: A method and apparatus for replacing the skin of an onscreen audio player through BIOS flash utility. When running the BIOS flash utility, the CPU retrieves an interrupt request from the BIOS, acquiring the skin stored in the storage device and replacing the default skin located in a ROM of the BIOS. Finally, the skin of the onscreen audio player is displayed on the output device.

Abstract: A method for activating a computer system audio player with a hot key. The present invention discloses a method for utilizing software to implement hot key function activating an audio player located in at least one system BIOS ROM of a computer system. When using the hot key, a keystroke is generated and transmitted to a keyboard controller. A CPU activates the audio player through at least one system BIOS determining if the key was used according to the scan code based on the keystroke, finally displaying the audio player on a monitor.
