Abstract: A structure for automatically rotating a spiral rod is provided. The structure allows a dusting cloth to be turned into a spiral shape along the spiral rod by rotating a rotating element, and, while the rotating element is being rotated, a torsion spring generates a restoring torque. Once the rotating element is no longer rotated, a pulling element pressing against the teeth inside the rotating element retains the rotating element and thus keeps the dusting cloth in the spiral shape. When the pulling element is subsequently pulled away from the teeth of the rotating element, the rotating element automatically rotates in the reverse direction due to the restoring torque of the torsion spring.

Abstract: A power supply device for a network attached storage (NAS) is connected to both a power over Ethernet (POE) system and a direct current (DC) power supply. A control unit of the power supply device receives a voltage provided by the POE system and a voltage provided by the DC power supply, and compares the two voltages with each other. When the voltage provided by the DC power supply equals or is greater than the voltage provided by the POE system, the control unit inputs electric power of the DC power supply to the NAS and prevents electric power of the POE system from being input to the NAS. When the voltage provided by the DC power supply is less than the voltage provided by the POE system, the control unit allows electric power of the POE system to be input to the NAS.
