Title: Jose R. Celaya and a Patent for Remaining Useful Life Prediction.

Introduction

Jose R. Celaya is an inventor associated with Sunnyvale, California. His patent work includes a prognostic technique for estimating the remaining useful life of components and subsystems.

Latest Patents

Celaya is credited with 1 patent: “Decomposition Technique for Remaining Useful Life Prediction.” The invention divides remaining useful life estimation into two regression problems: mapping measured features to damage, and mapping operating conditions to the rate of damage. These mappings are generated offline using measurements, operating conditions, and ground-truth information.

During online operation, sensor measurements and operating conditions are applied to the mappings to estimate the current damage state and project future damage accumulation. The remaining useful life is calculated from the predicted time at which damage reaches a failure threshold. By separating the estimation into distinct mappings, the technique supports explicit assessment and management of uncertainty.

Career Highlights

The patent is assigned to the United States of America, as represented by the Administrator of NASA. Its approach connects data-driven regression with equipment health monitoring and failure prediction.

Collaborations

Kai F. Goebel and Abhinav Saxena are identified as Celaya’s coworkers. Their shared work is associated with prognostics and methods for estimating the health and useful life of engineered systems.

Conclusion

Jose R. Celaya’s patent presents a structured approach to remaining useful life prediction, combining damage estimation, operating-condition analysis, and uncertainty management.
