Abstract: A light-emitting diode LED driver and a LED driving device including the LED driver are provided. The light-emitting diode LED driver includes a decoding circuit that receives a data signal and decodes the data signal to generate display data used to drive LEDs to emit light and display and a recovered clock signal. Further provided is an encoding circuit that encodes the decoded display data by using the recovered clock signal to generate an encoded data signal, where the data signal is encoded in a first encoding format, and the encoded data signal is encoded in a second encoding format.

Abstract: A fan comprises a fan frame, a motor, an impeller, a circuit board and an enclosing layer. The fan frame has a motor base disposed in a central portion thereof. The motor is mounted on the motor base and has a rotor, a stator and a bearing unit. The stator is disposed around the outer periphery of the bearing unit, and the rotor is sheathed on the stator and the bearing unit. The impeller is mounted on the motor. The circuit board is sheathed on the bearing unit and located between the stator and the motor base, and has a plurality of electronic components disposed on a first surface thereof. The stator and the circuit board are enclosed by the enclosing layer, and the plurality of electronic components are enclosed by the uniform enclosing layer with a specific thickness.

Abstract: An electrical device is provided in this invention, includes a main part having a pivot-receiving opening, an operation part having a pivot engaged pivotally to the pivot-receiving opening, and a flexible circular ring encircling the pivot, and being disposed and pressed between the pivot and the pivot-receiving opening.

Abstract: An air damping shockproof structure disposed between a hard disk and a system for damping or buffering a shocking or a vibration to the hard disk in the system. The air damping shockproof structure includes a top portion, a side portion, and a bottom portion, and an air chamber array disposed in the top portion. The air chamber array includes a plurality of air chambers, and a plurality of air outlets disposed corresponding to each air chamber respectively. The cross-sectional area of each air outlet is smaller than a cross-sectional area of each air chamber.
