Abstract: A method for controlling a fan in a fan start-up stage including a first time period and a second time period comprises the following steps of: during the first time period, continuously providing a first driving signal to drive the fan; and during the second time period, continuously providing a second driving signal to drive the fan; wherein, the signal value of the first driving signal gradually decreases until being equal to the signal value of the second driving signal. Wherein the signal value of the first driving signal non-linearly decreases, the signal value of the second driving signal is an unchanged value. Wherein, the first time period and the second time period are adjusted for a different fan but the sum of the first time period and the second time period is always the same. A fan is also disclosed.

Abstract: The present disclosure provides an adapter assembly. Portion of the main body of the plug adapter is penetrated through the opening and exposed to the exterior of the accommodation space. Each protrusion is penetrated through the concave and exposed to the exterior of the accommodation space. Each protrusion exposed to the exterior of the accommodation space is connected with the position-limiting portion through the rotation of the plug adapter. Each fastening element is plugged into the first hole and the second hole. The plug adapter is fastened to the casing through the fastening element and the connection between the protrusion and the position-limiting portion. The adapter assembly includes two impact bearing points. One is formed by the fastening element, and the other is formed by the connection between the protrusion and the position-limiting portion. The stability and the waterproof capability of the adapter assembly are enhanced.

Abstract: A system for compensating acceleration of electrical motorbike includes a throttle unit and an electro-mechanic assembly. After the electrical motorbike starts, the throttle unit receives external operation from a rider for generating a series of original throttle signal. An acceleration compensating module calculates a throttle variation rate based on the original throttle signal and variation of a throttle operation magnitude, and calculates a throttle compensating value based on the throttle variation rate when the throttle variation rate is larger than or equal to a correction threshold. A throttle compensating module receives and sums the original throttle signal and the throttle compensating value up for generating a new throttle signal. A torque controller generates a corresponding torque command based on the new throttle signal, and outputs the torque command to the electro-mechanic assembly for operation.
