Title: Kazuki Kunitoshi and Process-Trace Innovations

Introduction

Kazuki Kunitoshi is an inventor based in Chiba, Japan, whose patent work focuses on analyzing process-trace data to improve manufacturing insight and equipment reliability. He is associated with PDF Solutions, Incorporated, and has 2 patents.

Latest Patents

Kunitoshi’s recent patent work includes “Automatic Window Generation for Process Trace,” which describes defining analysis windows for process traces. For each process step, trace data are aligned with both the step’s start and end. Statistics, including rates of change, are calculated from each alignment, and the resulting analysis is used to generate windows.

His other recent patent, “Predicting Equipment Fail Mode from Process Trace,” concerns identifying equipment failure modes from trace data. When an anomaly is detected, key features are calculated and compared with past trace data in a database. If a matching or similar anomaly is found, the system can retrieve its type, root cause, and corrective action steps.

Career Highlights

Kunitoshi’s patent portfolio reflects an emphasis on applying data analysis to process monitoring. His inventions describe methods for organizing trace data and using historical patterns to support the diagnosis and correction of equipment problems.

Collaborations

Kunitoshi is associated with PDF Solutions, Incorporated. His listed coworkers include Richard Gene Burch and Michio Aruga.

Conclusion

Kazuki Kunitoshi’s two patents address process-trace analysis, from automatically generating analysis windows to using historical anomalies to predict equipment failure modes.
