Abstract: A method for selecting songs is provided, which is applied in an audio playback device. The method comprises obtaining a song file linked with the song title according to the song title selected by a user; reading a section from the song file according to the section of the song file designated by the user; providing a corresponding section number to the section; establishing a link between the song title and the section number for the section; joining up each section; and adding the song file linked with the section to a playlist according to the selected section and an instruction for adding it to the playlist.

Abstract: A method and system for managing data transmission between an external memory and an internal memory of an electronic apparatus is provided. The system includes an interactive interface for outputting messages that indicate real-time storage status of the internal memory and external memory card. When an external memory card is inserted, the system automatically duplicates files stored in the internal memory to the external memory card, and deletes the files in the internal memory upon determining that the files have been successfully transferred to the external memory card by matching the file names of the files in the internal memory to the external memory card. The system further includes a clamping means for securely clamping the portion of the external memory card that is exposed outside the electronic apparatus to avoid unintentional detachment of the external memory card from the electronic apparatus.

Abstract: A connector structure is proposed, which includes a body having at least one containing space; at least one first connector being inwardly disposed at one end of the body; at least one second connector being pivotally disposed on the other end of the body, which can be accommodated in the containing space of the body; and at least one rotating element being pivotally connected onto one end of the body, the second connector being fastened onto the rotating element, wherein the rotating element at least has one arm portion, one end of the arm portion being disposed with a pivotal connecting portion which connects to one end of the body. The connector structure further has a switch actuated by the rotation of the pivotal connecting portion of the rotating element thereof, wherein the rotation angle of the switch can control electric conduction of the first connector and the second connector.

Abstract: A backlight controlled closeup photographing system is proposed, which is designed for use with a multimedia-capable information platform, such as an MMV (MultiMedia Viewer) device, to allow the user to photograph a small object, such as a business card, at close range with intensified illumination on the object for the purpose of allowing the photographed digital image to have adequate brightness in picture quality. The proposed backlight controlled closeup photographing system is characterized by the use of backlight control to increase the intensity of the backlight illumination on the object being photographed for the purpose of allowing the photographed digital image to have adequate brightness in picture quality. Since the intensity of illumination on the object can be increased without using flash unit, the invention is apparently more cost-effective and advantageous to use than prior art.

Abstract: An automatic angle adjusting system for an image capturing device is provided, the image capturing device having an image capturing unit. The automatic angle adjusting system includes a driving device, an angle detector and a controlling device. The angle detector detects the location of the image capturing unit. The controlling device calculates an angle of the location of the image capturing unit deviating from a preset angle, and transmits a signal to the driving device that generates a mechanical driving force to rotate and resume the image capturing unit to the preset angle.
