Abstract: A resonance detection system includes a vibration simulation mechanism and a vibration audio analysis device. The vibration simulation mechanism includes a mechanism body that accommodates a peripheral interface device. The vibration simulation mechanism generates a vibration wave to the peripheral interface device. The peripheral interface device generates a vibration audio signal in response to the vibration wave. The vibration audio analysis device is electrically connected with the vibration simulation mechanism. After the vibration audio signal is inputted into the vibration audio analysis device, the vibration audio analysis device judges whether there is an abnormal resonance phenomenon in the vibration audio signal. The vibration simulation mechanism further includes a patch-type audio collector, which is electrically connected with the vibration audio analysis device. The patch-type audio collector is attached on the mechanism body containing the peripheral interface device. The vibration audio signal is collected by the patch-type audio collector.

Abstract: A method for aligning a camera lens with a light source is provided. The method is used in an aligning system. The aligning system includes an alignment element, a reference camera and a fixture. Firstly, the reference camera shoots a reference chart on the alignment element. Then, the light source is placed on the fixture. The light source illuminates the alignment element to generate an illumination result. The reference camera shoots the illumination result. If the illumination result does not comply with a preset specification represented by the reference chart, the fixture adjusts the light source. Then, the camera lens is placed on the fixture. Then, the camera lens shoots the reference chart on the alignment element to acquire a shooting result. If the shooting result does not comply with the preset specification, the fixture adjusts the camera lens.

Abstract: 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.

Abstract: A wireless input device includes an information receiving terminal and an information outputting terminal. The information receiving terminal generates a first-portion key. The information outputting terminal receives the first-portion key and generating a second-portion key. An original information is converted into an encrypted information by the information outputting terminal according to the first-portion key, the second-portion key and an encryption algorithm. The encrypted information and the second-portion key are transmitted from the information outputting terminal to the information receiving terminal. The encrypted information is restored to the original information by the information receiving terminal according to the first-portion key, the second-portion key and an encryption algorithm.

Abstract: A keyboard device includes a keyboard module and a palm rest module. The palm rest module is arranged beside a lateral side of the keyboard module, and supports a wrist of a user. The palm rest module includes a pedestal, a casing and an adjusting element. The casing is disposed on the pedestal. The adjusting element is arranged between the pedestal and the casing. A position of the casing relative to the pedestal is adjustable through the adjusting element. In a first usage state, the casing is moved toward the keyboard module or moved away from the keyboard module through the adjusting element. In a second usage state, the casing is rotated about the adjusting element and relative to the keyboard module, so that an included angle is formed between the casing and the lateral side of the keyboard module.

Abstract: A key structure includes a protective cover and a keycap. The keycap includes flow-guiding bevel surface. When the protective cover and the keycap are adhered on each other through a glue material, an excess portion of the glue material is retained on the flow-guiding bevel surface. Consequently, the excess portion of the glue material will not spread to other regions.
