  • Publication number: 20160164407
    Abstract: A method is provided for current compensation. The method is based on division-sigma (D-?) control for a DC/DC converter. Inductance changes are allowed with D-? digital control achieved. Loop gain can be quickly adjusted. The disadvantage of average current-mode control (ACMC) is solved, where the disadvantage is a reduction of the response speed caused by the filter within the current loop. The present invention uses midpoint current sampling to ensure taking an average inductor current value in each switching cycle. By doing so, a lack of fidelity of peak current-mode control (PCMC) is solved, where the lack of fidelity is due to the amount of error value between the peak value and the average value. Besides, the present invention uses a table of the inductance following current changes to achieve compensation of duty cycle ratio, where the table is built in a single chip.

  • Publication number: 20160151214
    Abstract: The present invention relates to an external skeletal fixator, which comprises a fixing member and a stereoscopic hood. The fixing member is disposed on a first end surface of the stereoscopic hood. The diameter of a second end surface of the stereoscopic hood is greater than that of the first end surface of the stereoscopic hood. When the stereoscopic hood is disposed to a pin passing through a skin tissue and a bone tissue, the second end surface of the stereoscopic hood is against the skin tissue surrounding a pin-skin interface and thus covering the stereoscopic hood over the pin-skin interface. The first end surface and a sidewall of the stereoscopic hood do not contact the pin-skin interface and the skin tissue around. Thereby, the contact area between the isolating structure and the pin-skin interface is reduced and the isolating structure blocks external germs from entering via the pin-skin interface.

  • Patent number: 9348748
    Abstract: Technology is described that increases endurance of memory devices through heal leveling. Heal leveling is a lightweight solution to distribute healing cycles among memory blocks. Approaches described herein can accomplish heal leveling without introducing a large amount of overhead. Heal leveling significantly improves the access performance and the effective lifetime of memory blocks. By more evenly distributing the heal count it may not be necessary to directly apply wear leveling based on access counts of each block because each block will be more evenly accessed in the long run. Heal leveling may be performed by moving data that is seldom or never modified after creation, such as read-only files, to blocks having suffered the greatest number, or a high number, of healing cycles.
