Abstract: An apparatus and method for expanding a box blank into a box, the apparatus comprising an arm assembly, a controller, a camera and a box blank conveyor. The arm assembly includes a folding arm having a position in a first direction and a rotational angle controlled by the controller based on a position of a feature of the box blank in the field of view of the camera. The camera captures images of the box blank which are used to position the arm assembly and to evaluate the need to reject a box blank.

Abstract: A portable folding wheelchair includes a front U-shaped tube and a rear U-shaped tube pivotally coupling with each other through a pin to form a X-shape. The front U-shaped tube has an upper end on two sides to fasten to a connection plate. The connection plate connects to a backrest. The front U-shaped tube has a lower section on two sides to pivotally engage with an upright tube. The upright tube and the rear U-shaped tube have an upper end bridging a sleeve. The wheelchair has a simple structure and may be folded in forward, rearward, upward and downward directions to become a smaller size to facilitate carrying or storing in a car to enable disabled people to use in travels and trips.
