Title: The Innovations of Henry E. Pfister
Introduction
Henry E. Pfister is a notable inventor based in Bakersfield, California, with a remarkable portfolio of seven patents. His work primarily focuses on advancements in error-correcting codes and data storage technologies, particularly in the realm of DNA data storage.
Latest Patents
One of Pfister's latest patents is titled "Reverse concatenation of error-correcting codes in DNA data storage." This invention addresses the inclusion of redundancy information in nucleotide symbol strings that encode underlying data. To prevent the propagation of errors during the decoding process, a constrained encoding is performed before computing the redundancy information. This redundancy can be interleaved into the nucleotide symbol strings, resulting in a relaxed constraint. Additionally, insertion and deletion redundancy information can be incorporated to assist in recovering accurate sequences during decoding operations.
Another significant patent is "Systems and methods for decoding forward error correction codes based on component codes." This invention outlines methods and apparatus for decoding forward error correction codes. It includes decoding multiple component codes, analyzing the decoding to generate outcomes, and estimating possible error locations. The process involves storing information related to these locations and updating state information accordingly.
