Abstract: An optical lens is configured in front of an image-capturing lens of an image-capturing device. A light-emitting unit of the image-capturing device emits a light beam. The optical lens includes a pair of peripheral compensation portions and a central diverging portion. Each peripheral compensation portion has a first convex surface and a first concave surface arranged opposite to the first convex surface. The central diverging portion is arranged between the peripheral compensation portions, and has a second concave surface and an oppositely arranged light incident surface. The second concave surface is arranged between the first convex surfaces. The light incident surface is arranged between the first concave surfaces. The optical axis of the light beam sequentially aligns with the light incident surface and the second concave surface. The light rays of the light beam pass through the first concave surface and the first convex surface in sequence.

Abstract: A joystick includes a stick head, an actuating component, a substrate, a bearing base, a resilient recovering component and a constraining component. The actuating component has a first end and a second end opposite to each other. The first end is connected to the stick head, and an identification feature is disposed on the second end. The substrate has a detection module used to detect the identification feature and determine motion of the stick head. The bearing base is disposed on the substrate. An opening portion of the bearing base aligns with the detection module and the actuating component. The resilient recovering component is disposed between the substrate and the bearing base. The constraining component is disposed on the resilient recovering component and movably disposed inside the opening portion, and used to abut against the actuating component in a detachable manner.

Abstract: A joystick includes a stick head, an actuating component, a substrate, a bearing base, a resilient recovering component, a first rotation component and a second rotation component. The actuating component has a first end and a second end opposite to each other. The first end is connected to the stick head, and an identification feature is disposed on the second end. The substrate has a detector used to detect the identification feature and determine motion of the stick head. The bearing base is disposed on the substrate. The resilient recovering component is disposed between the substrate and the bearing base. The first rotation component is movably disposed on the bearing base and rotatable in a first direction. The second rotation component is movably connected to the first rotation component and rotatable in a second direction different from the first direction, and connected to the actuating component in a rotatable manner.

Abstract: An optical sensing module including a lens and a sensing device is provided. The lens has an optical axis. The sensing device is disposed under the lens, wherein the sensing device is to receive an object beam passing the lens. The optical axis of the lens deviates from a geometric center of the sensing device. An optical sensing module including a prism film, a sensing device and a lens is further provided. The prism film has a plurality of prisms. The sensing device is disposed under the prism film, wherein the sensing device is to receive an object beam sequentially passing the prism film and the lens. The lens is disposed between the prism film and the sensing device.
