A radiating apparatus of a built-in refrigerator includes an airflow guide that separates a condenser from a blower fan in order to prevent a cool air and a hot air from mixing together, thereby increasing an efficiency of the built-in refrigerator. According to one embodiment, a method for autofocus based compensation of range data acquired from an object in motion is provided. Besides, the power-supply module further comprises a printed circuit board, and the at least one power-supply component and the inductor are mounted to the printed circuit board. Finally, the method, system, and computer program display the modified sheet metal part model on the computer display screen so that a user views modifications of the sheet metal part model in real time.
