Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: An electronic percussion instrument for suppressing sound source noise is described. The instrument includes a percussion pad, a metal plate disposed below the percussion pad, at least one damping element disposed in a ring-like manner below the metal plate, a resonance conductive member disposed below the damping element, a sensor disposed at a central region below the resonance conductive member, and a noise suppressing mechanism disposed at a peripheral annular region below the resonance conductive member. The noise suppressing mechanism includes, in an order from top to bottom, a foam ring and a metal ring. The metal ring has a plurality of cushioning elements thereon. Accordingly, the instrument can effectively suppress or otherwise eliminate interference on and noise sensed by the sensor caused by vibration of a casing when the percussion pad is percussed. This can greatly improve the sound effect and performance of the instrument.

Abstract: A charging and discharging system of a vehicle storage device utilizes a buffer device adapted for voltage adjustment toward a charging voltage of a charging device on the vehicle, and also for adjusting the charging current, in such a way that the charging voltage and current from the charging device may be reduced in advance for charging the storage device. With the charging and discharging system, storage device using lithium ion battery cell may be adapted to various vehicle system.

Abstract: A backlight module may include an optical substrate, at least one light guide pipe, and at least one first light source. At least one accommodation trench is disposed on the optical substrate for accommodating the light guide pipe. The first light source is disposed at one side of the light guide pipe and is arranged for emitting at least one first light into the light guide pipe. The first light is transferred in the light guide pipe and leaves the light guide pipe when being reflected by the optical substrate.

Abstract: A web camera suitable for capturing an image data and storing the image data in a portable storage device is provided. The web camera includes a photosensitive device, a processing chip, and a dynamic image processing chip. The photosensitive device is suitable for capturing the image data. The processing chip is coupled to the photosensitive device and is suitable for receiving the image data output by the photosensitive device. The dynamic image processing chip is coupled to the processing chip. When the image data is a dynamic image data, the dynamic image processing chip outputs a control signal to the processing chip, and the processing chip stores the image data into the portable storage device according to the control signal.
