Abstract: 본 발명은 광통신에 사용되는 광송수신모듈의 출력제어 및 감시방법에 관한 것이다. 광송수신기는 전기신호를 광신호로 바꾸어 광섬유를 통해 전송한 다음 다시 광신호를 전기신호로 바꾸어 수신하는 시스템이다. 따라서 전기신호를 광신호로 광신호를 전기신호로 변환하는 광송수신모듈이 필요하다. 광송수신모듈은 도 1과 같이 광송신부, 광수신부, 광출력제어 및 감시(Monitoring)부로 구성되어 있다. LD에서 나오는 광출력은 구동전류에 따라 변하는데 주변온도에 따라 구동전류에 대한 광출력 특성곡선이 변하게 된다. 따라서 APC(Automatic Power Control)를 사용하여 주위의 온도변화에 따라 광출력이 변화하는 것을 보상한다. 또한 LD alarm과 PD alarm 기능을 부가하여 전체모듈의 동작상태를 모니터링 할 수 있도록 한다. 현재 사용되고 있는 APC는 구동증폭기(Operational amplifier)를 사용하여 설정된 값을 유지하도록 구동전류를 변화시키는 아날로그방식을 사용하고 있다. 따라서 원하는 출력을 변화시키기 위해서는 수동으로 조정해야 하고 원격제어를 할 수 없는 단점이 있다. 본 발명은 광 출력 및 감시를 마이크로프로세서를 이용한 디지털 PID 제어방식을 이용하므로써 보다 빠르고 정밀한 출력을 조절할 수 있을 뿐 아니라 원격제어가 가능하다는 장점이 있다.

Abstract: 본 발명은 리프레쉬시 동작차단되는 지연동기회로에 대하여 기술된다. 본 발명은 외부클럭신호와 내부클럭신호의 위상차를 감지하는 지연동기회로를 포함하고, 외부클럭신호에 동기된 데이터를 출력시키는 반도체 메모리 장치에 적용된다. 지연동기회로는 위상검출기와, 저역필터, 그리고 가변지연단을 포함한다. 위상검출기는 노멀동작시 외부클럭신호와 내부클럭신호의 위상차를 감지하고 리프레쉬동작시에는 리프레쉬신호에 응답하여 디세이블된다. 저역필터는 위상검출기의 출력에 응답하여 소정범위를 갖는 제어신호를 발생하고, 가변지연단은 제어신호에 응답하여 외부클럭신호를 소정시간 지연시켜 내부클럭신호를 발생한다. 따라서 본 발명은 리프레쉬 동작 동안에 전원변동이 생기더라도 위상검출기 또는 지연동기회로의 동작이 차단되기 때문에 제어신호가 설정된 범위를 유지한다. 그리하여 내부클럭신호의 지터를 방지하고 출력 데이터의 유효 데이터 윈도우가 작아지는 것을 방지한다.

Abstract: PURPOSE: A method for applying an incentive by the usage of a card to a telephone charge is provided to receive a certain incentive without using the Internet and receiving an advertisement and freely perform a telephone conversation using the incentive. CONSTITUTION: An MSC(Mobile Switching Center) receives a card number, a password, and an object telephone number through a wired and wireless communication network, and compares the card number, the password, and the object telephone number with information stored in a client management server and a client database(201). If the card number, the password, and the object telephone number are identical to information stored in the client database, the card number is authenticated and the object telephone number is paged through the MSC(202). If an object is paged and a telephone conversation is performed(203), an accumulated incentive is decreased in proportional to a telephone conversation time. It is checked whether an amount of the decreased incentive is less than 0(204). If the an amount of the decreased incentive is less than 0, a minus incentive is generated or it is converted into a charged telephone conversation(208). If the an amount of the decreased incentive is more than 0, the incentive is decreased in proportional to an amount of the telephone conversation(205).
