Abstract: PURPOSE: A method for controlling a switching of a transceiving voice signal in a speaker phone mode of a cellular phone is provided to control transceiving states of voice data without using any equipment except for a cellular phone terminal, and thereby getting an efficiency of a hands free function, to reduce a sound intercepting phenomena caused when using a voice operated switch(VOX) function, and to control a half duplex operation or a full duplex operation according to a volume level of an other party outputted through a speaker CONSTITUTION: A controller checks whether an incoming call is received(S201). If so, the controller controls a ring signal generator, and outputs a ringer sound to an exterior(S202). A receiving subscriber perceives that a telephone rings through the ringer sound, and inputs a communication forming key(S203). The controller decides whether a speaker phone mode is set up(S204). If not, the controller forms a communication path for a general communication between the receiving subscriber and a transmitting subscriber(S209). If the speaker phone mode is set up, the controller enables a speaker phone, and operates the speaker phone in a speaker phone mode. The controller responds to the communication forming key, and forms the communication path for a general communication between the receiving subscriber and the transmitting subscriber. The controller decides whether a speaker phone volume level is set up(S205). If so, the controller checks whether the speaker phone volume level exceeds a predetermined level value(S206). If so, the controller turns on a voice operated switch(VOX), and forms a half duplex communication path(S207). If a communication completing key is inputted, the controller completes every step to complete every operation for communication between the receiving subscriber and the transmitting subscriber(S208). If the speaker phone volume level is not set up and the speaker phone volume level does not exceed the predetermined level value, the controller turns on the VOX, and forms a full duplex communication path.

Abstract: 본 발명은 자동차가 후진할 때, 자동차 운전석에서 자동차의 후면물체를 확인할수 있는 장치이다. 
     우리가 자동차를 운전하여 후진할 때 당연히 운전석에서는 후면을 볼 수가 없기 때문에 운전자는 차에서 하차하여 후면을 확인하여야하고 그렇게확인한후 후진운전을 하여도 불안감을 갖게마련이다. 
     특히 인지능력이 부족한 어린꼬마들의 경우에는 자동차가 후진하는 것을 보면서도 차뒤로 뛰어드는경우가 빈번하기 때문이다. 
     이와같이 자동차가 후진할때의 사고를 방지하기위하여, 현재시중에는 자동차뒤에 카메라를 장치하여 차량안에서 모니터를 사용하여 후방의 물체를 확인하는방법 
     또는 자동차뒤에서 음파를 발생하여 음파가 물체에 부딪혔을 때 발생하는 경보음을 발생하여 확인하는 방법이있다. 
     그러나 이러한방법들은 눈으로 실제물체를 보면서 후진운전을 하는 것이 아니기 때문에 장비에 고장이 발생하였을때는 치명적인 사고를 유발할수가있고, 가격도문제가 있어서 대중화에 문제가있다. 
     본 발명은 이러한사항들을 고려하여 자동차후진시 운전석에서 자동차후면의 장애물을 확인할수 있도록한 것이다 
     본 발명의 기본원리는 
     유리섬유[ GLASS FIBER]의 한쪽에 상을 투영하였을 때, 유리섬유[GLASS FIBER]은 이상을 전달하여 반대쪽에 상을 맺는원리를 이용한 것이다 
     현재 유리섬유{GLASS FIBER]의 이와같은 원리는 산업계에서 공업용 내시경 이라는 명칭으로, 사람이 직접볼 수 없는 기계내부의 결함을 확인하는등 여러부분에서 이용중이다. 
     즉, 유리섬유선을 자동차운전석에서 자동차후면까지 설치하였을 때 자동차후면에 있는 물체의상은 유리섬유를 통하여 자동차운전석에 있는 접안렌즈에 상을 맺으므로 운전자는 후진시 운전석에서 자동차후면의 장애물을 확인할수 있는 것이다.
