Abstract: A method of power saving for storage device with device queue management is proposed. A host controller is allowed to send commands or signals to a storage device, which will be notified to go to a low power stare or SLEEP mode, even when there are pending tasks left in a device queue waiting for execution. Similarly, the storage device is allowed to keep pending tasks before go to sleep and then restore the pending tasks by pushing the pending tasks back into the device queue again after waking up. Alternatively, the storage device notifies the host controller the number of pending tasks left in the device queue before go to sleep. The storage device can simply be awaken with an empty queue and the host controller will restart task queueing for the number of notified pending tasks again.

Abstract: A human-shaped adornment includes a supporting holder, which comprising a base and a supporting component; and a spiraled frame having a same axis with the supporting component. The spiraled frame includes a plurality of rings, which outline along its axis direction is a curve which is constituted by three arcs smoothly connecting with each other in a predetermined sequence; wherein the center of the three arcs are on a same line and their diameters gradually increase from top to bottom; the spiraled frame connecting with the supporting component through a connector having a plurality of connecting strings connected therewith for keeping the space between every two rings of the spiraled frame; wherein the connecting strings sequentially connects with each ring of the spiraled frame from top to bottom.
