Abstract:
A device for real-time self-diagnosis of a fan and a method are disclosed for detecting whether a fan body encounters an environment abnormal situation. The fan body includes a motor, a fan and a tachometer. The fan body further includes a microcontroller for receiving a speed signal of the tachometer and calculating a speed value of the fan, and detecting a current value of the motor during operation. The microcontroller can control the motor to drive the fan according to a monitoring period and a control signal transmitted from the control board, and can calculate a speed change amount according to the monitoring period, and can calculate a current change amount. When the speed change amount exceeds a speed change threshold and the current change amount exceeds a current change threshold for a period of time, the microcontroller generates an environmental anomaly signal.

Abstract:
A USB hub includes an upstream port; a first USB device control unit for performing packet format conversion; an FIFO circuit for storing data outputted from the first host; a second USB device control unit for performing packet format conversion; and a plurality of downstream ports. When any one of the downstream ports is coupled to the mobile device, if the first host commands the mobile device to switch to a host role from a device role, the mobile device temporarily disconnects from the USB hub, and the first host commands the USB hub to change an internal routing path. After the mobile device switches to the host role, the first host still performs the host role, and the first USB device control unit performs the device role; the mobile device performs the host role, and the second USB device control unit performs the device role.
