Hand-free operator capable of infrared controlling a vehicle's audio stereo system
First Claim
1. A hand-free operator coupled to a cellular phone through a signal cable for control of an audio stereo system of a vehicle, the audio stereo system having an infrared receiver, the hand-free operator comprising:
- a hand-free operator circuit unlit connected to said signal cable for receiving a signal from the cellular phone indicative of a mode of operation thereof, said hand-free operator circuit unit generating a command corresponding to said mode of operation of said cellular phone;
an infra-red circuit unit coupled to said hand-free operator circuit for receiving said command therefrom and for generating an infra-red signal in response to said command, said infra-red circuit unit transmitting said infra-red signal to said infra-red receiver of said audio stereo system through an optical communication link for controlling the functions of said audio stereo system in response to said mode of operation of said cellular phone;
a phonetic sound identifying unit having signal identification codes stored therein, said vehicle audio stereo system and said cellular phone being controlled by a user by inputting phonetic sound control commands into said hand-free operator.

Abstract
The disclosure relates to an infrared controlled hand-free operator for cellular phones housed in a vehicle. More particularly, it is concerned with a hand-free operator which can automatically transmit an infrared signal similar to a control signal of a vehicle'"'"'s audio stereo system to turn the stereo system off or mute when income signals are received by a cellular phone mounted to a vehicle. The hand-free operator thus can automatically cut off the noise sound of an audio stereo system in operation so as to make the operation of a cellular phone free of interference in a vehicle on the move.
