Title: Innovations of Xiaohong Li

Introduction

Xiaohong Li is an accomplished inventor based in Clifton Park, NY (US). She holds three patents that showcase her expertise in advanced technologies. Her work primarily focuses on modular multilevel converters and holographic storage mediums.

Latest Patents

One of her latest patents is titled "Switching synchronization for modular multilevel converters." This invention provides a modular multilevel converter and a method for synchronizing outputs of sub-modules of the converter. The modular multilevel converter includes sub-modules connected in parallel, and each sub-module generates an output. The converter also features a controller that is communicatively coupled to the sub-modules. This controller manages the flow of one or more synchronizing signals between the sub-modules, ensuring that each sub-module receives the synchronizing signals in opposite directions simultaneously, thereby controlling the synchronization of the outputs generated by the sub-modules.

Another significant patent is the "Method and system for processing information from optical disk layers." This method involves directing a laser beam to a first track of a first layer of a holographic storage medium. It includes recording a base voltage based on a look-up table and directing the laser beam to a target track in the first layer based on position information in tracks. The method also records an offset voltage for the target track into the look-up table and directs the laser beam to a target layer based on position information in vertical wobbles. Finally, it determines a final voltage based on the look-up table and applies this voltage to an actuator for moving the laser beam to a final target position in the holographic storage medium for recording and retrieval of information.
