Abstract: An electronic device having multiple human-machine interfaces and a method for running multiple human-machine interfaces are provided. The electronic device includes a host and a plurality of human-machine interfaces. The host has a processor, and each of the human-machine interfaces is disposed in the host and includes a power setting module. The processor analyzes all the human-machine interfaces to determine a target interface in which the enabled power setting module is included, so as to perform message input and output operations of the target interface.

Abstract: A complex type supporting frame used to allow an electronic device to stand on or to be hung on a mounting surface. The complex type supporting frame includes a supporting part and a fixing part disposed surrounding the peripheral of the supporting part. The supporting part includes a device connection structure to support the electronic device. A positioning structure is disposed at the peripheral of the fixing part.

Abstract: The present invention provides a vertical-axis windpower fan unit using a central axle having modulized design for assembling or disassembling quickly and includes supporting arms with capability of weight adjustment so as to balance the rotation of the fan unit. In one embodiment, the present invention further provides a coaxial fan module comprising a plurality of fan units coupled sequentially wherein a blade of each fan unit is disposed in the middle position with respect to the two blades of the adjacent fan unit for reducing unbalance and eliminating vibrational noise while the fan module is rotating. In addition, in another embodiment, the present invention further provides a power generating system comprising the coaxial fan module and a power generator unit coupled to the coaxial fan module so as to generate electricity.
