Abstract: An electrical device capable of auto-adjusting display direction according to a tilt of a display is provided. The electrical device includes a housing, a display panel installed on the housing, a gravity sensor for outputting a sensing parameter based on a tilt angle of the display panel, a direction control device for generating direction signals, and a micro-controller for adjusting the display direction of the display panel based on the sensing parameter and for adjusting the indicated direction corresponding to direction signals generated by the direction control device.

Abstract: Method and device for wireless data transmission and storage. The device is a remote wireless data storage system including a remote data processing subsystem for receiving an audio signal and a central data processing subsystem for data storage. The remote data processing subsystem sends information corresponding to the audio signal to the central data processing subsystem through wireless transmission, and the central data processing subsystem stores the information. Furthermore, the remote data processing subsystem receives stored information corresponding to an audio signal from the central data processing subsystem through wireless transmission and outputs a reconstructed audio signal corresponding to the stored information.

Abstract: A wireless fingerprint identity apparatus and method for electronic system security. The apparatus includes an identity device, a receiver module, and a fingerprint identification module. The identity device has a radio frequency (RF) module, which is able to transmit fingerprint data, gathered by a fingerprint image sensor, by a wireless transmission protocol. The fingerprint identification module is coupled to the receiver module and a memory module to save predetermined fingerprint data, wherein the fingerprint identification module differentiates the fingerprint data received by the receiver module, from predetermined fingerprint data and controls the electronic system accordingly.
