Duplex communication apparatus for motor vehicle
First Claim
1. A duplex communication apparatus for a motor vehicle comprising a sensor mounted on a windshield being activated when a predetermined pressure is exerted thereon, a first cellular phone mounted in said motor vehicle being charged by a battery of said motor vehicle, an alarm coupled to said apparatus, a radio frequency (RF) module for receiving signals from or transmitting signals to an antenna of said motor vehicle, a first decoder, a central processing unit (CPU), a memory unit, an input unit for sensing signals sent from one of a plurality of motor vehicle components, an output unit activated in response to said signals received from said input unit, a voice generator, a dual-tone multi-frequency (DTMF) decoder, and a speaker wherein said first cellular phone and said alarm are switched to a ready state when a motor vehicle owner leaves said motor vehicle so that in a first case that said sensor is enabled by a person said apparatus is activated and said alarm is disabled simultaneously, whereby a two-way communication is established between said motor vehicle owner and said person through said sensor, said CPU, said voice generator, a second cellular phone carried by said motor vehicle owner, and said speaker;
- in a second case that both said sensor and said alarm are enabled because said motor vehicle is towed away by a tow truck said apparatus is activated, whereby a two-way communication is established between said motor vehicle owner and an law enforcement officer in charge of said tow truck through said sensor, said CPU, said voice generator, said second cellular phone carried by said motor vehicle owner, and said speaker; and
in a third case that both said sensor and said alarm are enabled because said motor vehicle is broken into by a theft said apparatus is activated, whereby a two-way communication is established between said motor vehicle owner and said theft through said sensor, said CPU, said voice generator, said second cellular phone carried by said motor vehicle owner, and said speaker so as to be capable of disabling said motor vehicle in a remotely controlled manner.
