Claims (2)

초음파를 발생하는 송신부(T)와 초음파를 수신하는 수신부(R)를 결합하여 초음파의 수신 여부에 따라 임의로 조정할 수 있는 시청 안전 거리 내외에 위치한 인체의 유무에 의하여 접점 릴레이(RL)가 동작되어 텔레비죤의 입력 전원을 개폐할 수 있게 함을 특징으로 한 텔레비죤 보안기의 시스템.The contact relay RL is operated according to the presence or absence of a human body located within and outside the viewing safety distance that can be arbitrarily adjusted according to the reception of the ultrasound by combining the transmitter T generating the ultrasound and the receiver R receiving the ultrasound. A television security system, characterized in that the input power can be opened and closed. 제 1 항에 있어서 초음파의 수신 여부에 따라 임의로 조정할 수 있는 시청 안전 거리 내외에 위치한 인체의 유무에 의하여 가변 릴레이(RL1)가 동작되어 텔레비죤의 휘도를 조정하여 화면을 어둡게 하거나 원상태로 유지할 수 있게 하여서 된 것.The variable relay RL 1 is operated according to the presence or absence of a human body located within and outside the viewing safety distance that can be arbitrarily adjusted according to the reception of ultrasonic waves, thereby adjusting the brightness of the television to dim or maintain the screen. It was done. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
