Abstract: A luminous fan includes a supporting mechanism, a main circuit board, a light-guiding impeller and an illumination module. The light-guiding impeller is pivotally coupled to a bracket of the supporting mechanism. The illumination module is disposed within a hub of the light-guiding impeller. After a light beam from a light-emitting element of the illumination module is emitted to a lens assembly, the light beam is refracted by a secondary lens of the lens assembly and transmitted to the light-guiding impeller. Consequently, the light-guiding impeller is illuminated.

Abstract: A computing device and an input device are provided. Each of the computing device and the input device includes a control unit, a light source, a projection plate and a casing. The control unit, the light source and the projection plate are accommodated within the casing. The light source emits light beams. The projection plate includes a pattern. After the light beams pass through the projection plate, the light beams are projected outside the casing and an image corresponding to the pattern of the projection plate is formed on a projection surface that is located outside the casing. Since the projection plate is cheap and small, the fabricating cost of the computing device or the input device is reduced and the purpose of developing the computing device or the input device toward light weightiness, slimness and small size is achievable.

Abstract: A touch feedback correction method and a touch module using the touch feedback correction method are provided. In the touch feedback correction method, the coordinate values and the initial vibration values of plural press region on a touch panel of the touch module are detected. Consequently, a driving voltage calibration table is established. Then, a vibrating unit of the touch module is driven according to plural compensated voltage values of the driving voltage calibration table. Consequently, the plural press regions generate plural corrected vibration values, respectively.

Abstract: A touchpad module includes a base plate, a touch member, a supporting structure and a pressure sensing unit. The touch member is movable toward the base plate. The supporting structure is arranged between the base plate and the touch member. The pressure sensing unit is installed on the touch member. The pressure sensing unit is arranged between the touch member and the base plate. While the touch member is pressed in response to an external pressing force, the touch member is moved downwardly toward the base plate to compress the supporting structure. Consequently, the supporting structure is subjected to deformation, and the touch member has a displacement amount. According to the displacement amount, a magnitude of the pressing force is sensed by the pressure sensing unit, and a pressure sensing signal is outputted from the pressure sensing unit.

Abstract: A luminous fan includes a fan frame, a main circuit board, a light guide element and a light-guiding impeller. The main circuit board is disposed on a bracket of the fan frame and includes a first light-emitting element. The light guide element is located over the main circuit board, and includes a light input surface and light output surface. A light guide post is disposed on the light input surface. A reflective structure is formed on the light output surface. The light-guiding impeller is pivotally coupled to the bracket. The first light-emitting element emits a first light beam. After the first light beam is transmitted to the reflective structure through the light guide post, the first light beam is reflected by the at least one reflective structure and diffused toward a middle region of the light guide element.
