Abstract: A DVB-T direct down conversion modulator using a frequency shifter and a modulating method thereof are provided to simplify a high frequency processing circuit without an intermediate frequency conversion unit by removing influence of a leakage signal of an intermediate frequency. A high frequency receiver generates a signal of an oscillation frequency satisfying a predetermined formula.

The high frequency receiver outputs I and Q signals by the mixed result. A first frequency shifter(29) preforms the frequency shift so that a band center of a target signal becomes 0 by using I and Q signals. A signal extractor extracts the I and Q signal of a target signal from a frequency shifted signal. A second frequency shifter(32) performs the frequency shift as much as 1/2 of the target signal band by using the extracted I and Q signals.

Abstract: 본 발명은 로봇청소기를 이용하여 집안을 청소하고자 할 때 문턱이나 가구 밑 등 이동하는 로봇의 진행을  방해하는 요소 혹은 자동 충전 장치를 검출하기 위해 거리를 검출할 수 있는 센서를 전방 혹은 상단, 하단, 좌우 측방에 임의의 각도로 부착하여, 로봇이 진행하는 방향의  방해요소를 회피하거나 계속하여 진행할 수 있도록 하는 센서의 부착방법과 검출방법을 포함하며; 이로써 로봇의 상단,하단이 가구 밑이나 문턱 등에 걸려 더 이상 이동할 수 없는 상황이 되어 로봇청소기의 본래 목적인 청소를 하지 못하는 상황을 방지하고 배터리의 충전이 필요한 경우 자동 충전 장치를 인식하고; 또한 이러한 상황에서 생기는 과부하로부터 로봇이 손상되는 것을 막을 수 있도록 한 것이다. 이를 위해 본 발명은 로봇 청소기의 전방 혹은 상단, 하단, 좌우 측방에 검출 대상 물체에 대해 임의의 각도로 거리를 검출할 수 있는 수단을 설치하고 로봇의 이동이 진행되는 동안 거리 값을 측정하여, 그 값의 증가, 감소 혹은 같음을 이용하여 장애물의 높이와 모양을 측정하고 이를 토대로 로봇청소기가 진행할 수 있는 영역인지를 판단하여 장애요소를 회피 혹은 계속 진행할 것인지를 판단하게 하는 중요한 자료로 사용될 수 있도록 하기 위해; 센서를 물체에 대해 임의의 각도를 갖도록 하여 설치하는 방법과 센서의 정보를 토대로 장애요소를 판단하는 제어수단을 포함한다.
