Abstract: An intelligent fan with interface compatibility is provided. The intelligent fan includes a fan body having a fan and a motor, a driving circuit, a tachometer, an output connector including a first pin, a second pin, a third pin and a fourth pin connected to a fan connector of a motherboard, and a microcontroller connected to the driving circuit and the tachometer, and connected to the motherboard via the first, second, third and fourth pins. When the intelligent fan is powered on, the microcontroller sets the third and fourth pins as input pins for receiving an output signal of the fan connector of the motherboard, and the microcontroller performs an I2C signal analysis on the output signal. When the I2C signal analysis succeeds, the intelligent fan is set in an I2C mode, and when the I2C signal analysis fails, the intelligent fan is set in a PWM mode.

Abstract: A system for achieving display of CarPlay operation interface on display screens of multiple electronic devices is disclosed. The system comprises a first electronic device and a second electronic device, wherein the first electronic device has functionality of Apple CarPlay because of including an Apple Mfi authentication chip. Particularly, a CarPlay executor comprising a principal execution unit and a plurality of sub-execution units is provided in the first electronic device. As such, after a second mobile electronic device is in communication with a second electronic device that is coupled to the first electronic device, one sub-execution unit is authorized by the Apple Mfi authentication chip so as to let a CarPlay operation interface be shown on a display screen of the second electronic device, thereby achieving display of CarPlay operation interface on display screens of multiple electronic devices.
