Abstract: A method for controlling barrier door is disclosed. The method includes following steps of: monitoring a barrier door (20) for generating multiple monitor images continually via a monitoring camera (104); recognizing a barrier door feature pattern (30-34) arranged on the barrier door (20) from the monitor images and determining a shade status of the barrier door feature pattern (30-34); recognizing a movement feature pattern arranged on a movable object from the monitor images and determining a movement direction of the movement feature pattern continuously; controlling the barrier door (20) to open when the shade status is consistent with a default shade status, the movement direction is consistent with a default movement direction, and the barrier door (20) is closed. Therefore, the barrier door can automatically and timely open without arranging the RFID reader, so as to provide the user the batter convenience.

Abstract: A rotary casing of a satellite antenna having an angle adjustable display screen includes a supporting arm, a hollow casing, a rotating means and an adjusting and controlling assembly. The casing has a panel provided with two keys and a top surface provided with a window. The rotating means is provided in the casing and controlled by the keys to drive the rotation of the supporting arm. The adjusting and controlling assembly is provided in the casing and includes a control unit and a display unit. The two keys are electrically connected to the control unit to drive the supporting arm. By this arrangement, the control unit receives an adjustment instruction inputted by the keys and transmits the instruction to the rotating means to generate a corresponding amount of rotation, while the control unit converts the instruction into a numerical value to be displayed on the display unit.
