Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: Systems and methods of making a glove pack and for removing gloves from the glove pack are disclosed. The glove pack includes a stack of gloves. The stack of gloves includes a first glove engaging a second glove. The first and second gloves each have an exterior gripping surface. Each exterior gripping surface of the first and second gloves engages and adheres to the exterior gripping surface of the other of the first or second glove in the stack of gloves thereby adhering the first and second gloves together in the stack of gloves such that when the first glove is removed from the stack of gloves at least a portion of the second glove moves with the first glove.

Abstract: A method for facilitating caries detection is to be performed based on a grayscale image of teeth, and includes: obtaining an object detection model; obtaining a detection image using the object detection model based on the grayscale image, wherein the detection image is the grayscale image labeled with a plurality of tooth crown marks and a caries mark; and for one of the tooth crown marks that has the caries mark provided thereon, determining a width and a height of the tooth crown mark and a width and a height of the caries mark, and calculating a caries ratio based on the aforementioned widths and heights to obtain an evaluation result that indicates a severity of caries.
