PURPOSE: A vehicle information update system using a wireless internet sharer connected with a telematics server and method thereof are provided to rapidly download update files by connecting to the telematics server through the wireless internet sharer. CONSTITUTION: When vehicle information for update files is existed in a telemetric server(300), a wireless communication unit(101) automatically receives the update files by connecting to a wireless internet sharer through a Wi-Fi method. A control unit(103) manages apparatuses corresponding to vehicle information and the vehicle information and stores the update files transmitted by the wireless communication unit. An update unit(105) updates the vehicle information by using the update files. The wireless communication unit searches adjacent wireless internet sharers.

PURPOSE: A multiple inspection apparatus for the multimedia devices of a vehicle is provided to improve the efficiency of quality inspections by inspecting the quality of the devices with the inspection apparatus instead of a sensory inspection. CONSTITUTION: A sound source module(140) output pre-stored sound source or a pre-set melody through a voice signal input unit. A level meter(150) receives voice signal through the microphone of a hands-free and visually displays the sound pressure level of the voice signal. Power is applied to a power input unit(180) through a cigar jack power source.

PURPOSE: A falling preventing and warning system is provided to prevent a fall of an article and an accident by keeping the suction force of a suction pad although the supply of compressed air is stopped. CONSTITUTION: A vacuum suction system is formed by connecting a vacuum pad(5) to a vacuum ejector(4) having a compressed air nozzle(3) via a suction passage(6) and connecting an exhaust passage(4) of the vacuum ejector to a muffler(8). A pressure switch(9) is mounted between a supply passage(2) of a compressed air source(1) and the vacuum ejector. A solenoid valve(10) is installed between the vacuum ejector and the suction passage. The pressure switch is connected to a warning lamp, a buzzer, and the solenoid valve. If the supply of compressed air to the vacuum ejector is stopped, the pressure of the supply passage falls and the pressure switch is actuated. Then, electrical signals are applied to the solenoid valve, the warning lamp and the buzzer to let a worker recognize the pressure falling state. The suction passage is closed to keep the vacuum force of the vacuum pad.
