Abstract: A variable aperture module includes a blade assembly, a positioning element, a driving part and pressing structures. The blade assembly includes movable blades disposed around an optical axis to form a light passable hole with an adjustable size. Each movable blade has a positioning hole and a movement hole adjacent thereto. The positioning element includes positioning structures disposed respectively corresponding to the positioning holes. The driving part includes a rotation element disposed corresponding to the movement holes and is rotatable with respect to the positioning element. The pressing structures are disposed respectively corresponding to the movable blades. Each pressing structure is at least disposed into at least one of the positioning hole and the movement hole of the corresponding movable blade. Each pressing structure at least presses against at least one of the corresponding one positioning structure and the rotation element.

Abstract: A system module applied to the machine controller for simulating a machine operation screen based on a non-invasive data-extraction system, is disclosed. An image capture device of the system module can receive an original operation screen outputted from the machine controller, and transmit the original operation screen to the non-invasive data-extraction system and a high-speed image process unit for extraction of the information shown on the operation screen. The software control system can extract the operational information of the machine controller in real time, to create a machine operation flow for generating a simulated machine operation screen which is then outputted to a screen of the machine controller. As a result, the site working staff can be provided with operational information associated with the machine in real time, for example, the operational information includes currently executed operation screen, position of mouse cursor and pop-up window detection result.
