Personal rescue system

摘要

A personal rescue system in which the car driver can double-click the emergency button of a personal remote control secretly to send an emergency signal to an on-board movable alert device when extorted by evil fellows, causing the controller of the movable alert device to turn the audio/video output device of the movable alert device into a background mode and then to drive the wireless communication device of the movable alert device to send a rescuing message to a remote side wirelessly under the background mode without infuriating the evil fellows.
