The accommodation structure has a first opening, a second opening and a third opening. The push button includes a pin, a pressing post, a positioning post, a retaining plate and a spring. The pin is penetrated through the first opening. The pressing post is penetrated through the second opening. The positioning post is penetrated through the third opening. The turntable mechanism includes plural fourth openings. When the pressing post is not depressed, the pin is inserted into one of the plural fourth opening, so that the turntable mechanism is fixed on the base body. After the pressing post is depressed and the pin is detached from the fourth opening, the turntable mechanism is rotatable relative to the base body.

摘要： A doorbell system includes a power supply circuit, a smart module, a chime, a chime switch and a control module. The smart module provides a smart function. The chime switch is electrically connected between the control module, the smart module, and the power supply circuit. When the chime switch is turned on, the current flows through the chime under control of the control module. When the chime switch is turned off, the current cannot flow through the chime under control of the control module; consequently, the buzzing sound cannot be generated.

摘要： A USB interface detection module includes a detection unit and an adapting device. The adapting device is electrically connected between a first electronic device and a second electronic device. According to the interface specification of the first electronic device, the voltage value of a configuration channel pin is changeable through the use of the GND_DRAIN pin and the switching action of a field-effect transistor switch. Consequently, the interface specification of the first electronic device is acquired by the second electronic device.

摘要： A luminous keyboard includes a keyboard module and a backlight module. The backlight module is located under the keyboard module. The backlight module includes a light source, a light guide plate and a reflecting plate. The light source includes a conductive substrate and plural light-emitting elements. The light guide plate includes a light input surface, a light exit surface, a bottom surface and a first slot. The light input surface is disposed within the first slot. The reflecting plate is disposed on the bottom surface of the light guide plate. The reflecting plate includes a second slot. The second slot is in communication with the first slot. The conductive substrate is penetrated through the second slot and the first slot. Consequently, the plural light-emitting elements are accommodated within the first slot and aligned with the light input surface.

摘要： A camera module aligning method includes the following steps. Firstly, a reference chart having plural chart characteristic points is provided. Then, a camera module is used to shoot the reference chart, and an installation position and an installation posture of the camera module are acquired according to an internal parameter matrix and an external parameter matrix. When the camera module shoots the reference chart and an image is formed on an imaging plane of the camera module, a relationship between at least one image characteristic point of the image and the corresponding chart characteristic point complies with a standard relationship. The standard relationship is defined by the internal parameter matrix and the external parameter matrix.

摘要： A touchpad module includes a bracket, a touch member and a supporting assembly. The touch member is located over the bracket. The touch member includes a membrane wiring board and a circuit board. The circuit board is located over the membrane wiring board. The supporting assembly is arranged between a second end of the touch member and the bracket. While a first end of the touch member is pressed down, the first end of the touch member is swung relative to the bracket. Consequently, a membrane switch of the membrane wiring board is triggered. The present invention further provides a computing device with the touchpad module.

摘要： A touch module includes a touchpad assembly and a connection assembly. The connection assembly includes a main body, plural first coupling plates and plural protrusion posts. When the connection assembly is accommodated within a computer casing, the plural first coupling plates are penetrated through plural first openings of the computer casing and the plural protrusion posts are inserted into the corresponding fixing structures. The plural protrusion posts and the corresponding fixing structures are collaboratively formed as a hinge structure. While the touchpad assembly is pressed down, the connection assembly is swung relative to the computer casing by using the plural protrusion posts as the pivotal shafts, so that the touchpad assembly is correspondingly swung. Due to the hinge structure, the touchpad assembly is swung along a fixed direction. Consequently, the touch module is operated stably.
