Shannon Systems Assigned Patent

Shannon Systems Ltd., Shanghai, China, has been assigned a patent (10,474,214) developed by Ye, Xiawei, Shanghai, China, for “data storage device and method for monitoring power storage capability of secondary power of data storage device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An apparatus and method for monitoring the power storage capability of a secondary power source of a data storage device is provided. A capacitor is used as a secondary power source. A charging path and a discharging path are selectively generated for the capacitor. After being charged through the charging path, the capacitor is then discharged through the discharging path while the charging path is disconnected from the capacitor. Then, the capacitor is checked to determine whether its voltage level has dropped below a threshold level and thereby an evaluation result obtained from evaluating the capacitor is generated.”

The patent application was filed on August 3, 2017 (15/667,703).
