    Abstract: There is provided an optical raindrop detector including a light source, a light guide, an image sensor and a processing unit. The light source alternatively emits light with different brightness values. The light guide has an incident surface, a detection surface and an ejection surface, wherein the light source emits incident light into the light guide via the incident surface, and a plurality of microstructures are formed on the ejection surface to reflect the incident light to become scattered light toward the detection surface. The image sensor receives reflected light formed by raindrops in front of the detection surface reflecting the scattered light to penetrate the light guide and eject from the ejection surface, and generates image frames corresponding to the different brightness values of the light source. The processing unit calculates differential images of the image frames to accordingly identify rain intensity.

    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.
