Abstract: A dockable device and a power method thereof are provided. The dockable device includes a main device, a main device battery, a connecter, a switch and a voltage down-converter. The connecter may be coupled to a docking device. The switch, coupled to the main device battery, is configured to be closed to provide power to the main device from the main device battery. The voltage down-converter is configured to provide power with a backup voltage to the main device, wherein the backup voltage is less than a discharge voltage output by a fully discharged main device battery.

Abstract: A corrugated cabinet of the present invention is provided with a main body and a back plate. The main body consists of several vertical plates and several transversal plates, which define at least two compartments therebetween. Each compartment has a rear opening, which is sealed by the back plate. The back plate includes several cardboards that are entirely enveloped by a paper skin. Furthermore, a seam is interposed between each two adjacent cardboards, and the seam has a width substantially equal to a sum of thicknesses of the two cardboards. Whereby, the back plate is foldable along the scam and becomes less space-consuming before sealing the rear openings.

Abstract: A paperboard assembly includes a paperboard with hook-loop member connected to at least one side of the paperboard. The paperboard includes a top board, a bottom board and a mediate portion which is connected between the top board and the bottom board. The paperboard assemblies can be connected to each other or separated from each other by the hook-loop members. The paperboard assemblies are connected in a specific arrangement to from a desired shape.

Abstract: An arm circulation system stretching, recuperative chest enlargement and respiration assistance apparatus consisting of a swinging appendage disposed at each of the two sides capable of synchronously ascending and descending at a slow rate. The speed of the swing is controlled by the user in a supine position whose arms are spread out on the swinging appendages and holding a remote controller in the palm to control the forward/reverse rotation of the speed reduction motor driving the swinging appendages as well as the upward and downward position of a sleeve on the drive motor screw rod.
