Introduction

JingFeng Liu is an inventor associated with Pittsburgh, Pennsylvania, and the Data Storage Institute. His patent work addresses how multilevel data arrays can be prepared for reliable recording in multidimensional storage media, including holographic storage.

Latest Patents

Liu is credited with 1 patent: “Method and Apparatus for the Modulation of Multilevel Data Arrays.” The invention describes a method for producing a modulated data array with frequent transitions between symbol levels and constant energy at the recording plane.

The method first combines the input array with a randomly generated multilevel array using modulo-q addition. It then applies a q-ary balanced complementary method to adjust symbols in horizontal row-by-row readout order. The resulting array is designed to satisfy both the transition and energy constraints, supporting its use in multidimensional storage systems.

Career Highlights

Liu’s listed patent reflects work on data encoding and storage technology. By addressing signal uniformity and energy balance, the invention aims to make multilevel data arrays more suitable for recording and retrieval in holographic storage media.
