Abstract: A digital audio ripping device is proposed, which is designed for use to convert the digital audio data that are stored in a particular format on a storage medium, such as Audio CD files, into a standard computer multimedia format, such as the MP3 format, such that the user can utilize a portable MP3 player for playback of MP3-formatted digital audio files extracted from Audio CD. The proposed digital audio ripping device is characterized by the capability of Audio CD ripping to an MP3 multimedia player without having to use a PC, and the capability of performing a folder reorganizing procedure in the event of the MP3 multimedia player being downloading and installing an iTunes program via the Internet so as to allow the MP3 multimedia player to use the iTunes program for playback of the digital audio files extracted from the Audio CD.

Abstract: A pen-based input and data storage device is proposed, which is designed for use with an information platform of the type having a touch screen for pen-based input functionality, such as a tablet computer or a PDA (Personal Digital Assistant), for the purpose of allowing the user to use it either as a pointing pen for pen-based data input via the touch screen to the information platform, or as an external data storage unit for the information platform. The proposed pen-based input and data storage device is advantageous to use in that it allows the user to conveniently transfer data from tablet computer or PDA to another information platform without having to use cables or infrared transmitters, which makes it more conveniently and cost-effectively to use than prior art.
