Abstract: A coated metal alloy substrate with at least one chamfered edge, a process for producing a coating a metal alloy substrate, and an electronic device having a housing comprising a coated metal alloy substrate are described. The coated metal alloy substrate with at least one chamfered edge comprises a hydrophobic anti-fingerprint layer deposited on the metal alloy substrate, a passivation layer deposited on the at least one chamfered edge, and a water based paint layer deposited on the passivation layer.

Abstract: A fan and a motor are provided. The fan or the motor includes a shaft seat disposed on a frame, a rotor, and a stopping assembly. The rotor is disposed on the shaft seat and includes a hub and a rotation shaft. The hub has a first locking mechanism adjacent to its peripheral surface, and the rotor is connected to the shaft seat via the rotation shaft. The stopping assembly corresponds to the rotor, and includes a second locking mechanism facing the first mechanism. When the rotor smoothly rotates, the first locking mechanism is separated from the second locking mechanism. When the rotor rotates in reverse, the stopping assembly moves along a first direction, and the first and second locking mechanisms contact each other. When the first locking mechanism is affixed to the second locking mechanism, the rotor stops rotating.

Abstract: A recognition system and a recognition method are provided. The recognition system includes a camera having a wide angle-of-view, a transmitter electrically connected to the camera, and a processor communicating with the transmitter. The camera is mounted on a body or a finger of a user, and captures one or more raw images of the limbs or hands. The transmitter transmits the one or more raw images of the limbs or hands to the processor. The processor transforms the one or more raw images of the limbs or hands into a corresponding gesture image, builds a recognition module according to a plurality of gesture images of the limbs or hands, and recognizes one or more new raw images of the limbs or hands captured by the camera with the recognition module so as to recognize a bodily gesture or a hand gesture.

Abstract: A fan structure is provided, including a hub and a plurality of blades surrounding the hub. Each blade has a first segment connected to the hub and a second segment extended outwardly from the first segment. A first surface is formed between the first segment and the hub, and a second surface is formed between the first and second segments. The first and second surfaces respectively have a first and second setting angle relative to a base plane of the fan structure, wherein the first setting angle exceeds the second setting angle.

Abstract: The present invention provides a fan including a stator and a rotor coupled to the stator. The stator has a base and a bearing disposed inside the base. The rotor has a shaft supported by the bearing. Furthermore, the shaft has a concave structure formed on a surface thereof, or the bearing has a groove structure formed on a surface thereof.
