Title: Yuchao Liu and Ophthalmic Laser Safety Testing

Introduction

Yuchao Liu is an inventor based in Irvine, California, whose patent work addresses safety testing for laser diodes used in ophthalmic surgical equipment. His disclosed approach compares a laser diode’s measured performance with an expected value adjusted for the apparatus’s operating temperature.

Latest Patents

Liu is associated with 1 patent: “Techniques for Performing a Safety Test of a Laser Diode Ophthalmic Surgical Apparatus.” The method determines the diode’s measured slope efficiency using multiple input-current levels and corresponding output-power levels. It then determines an expected slope efficiency based on the apparatus’s measured operating temperature, evaluates the safety-test result by comparing the measured and expected efficiencies, and outputs an electrical signal indicating that result.

Career Highlights

Liu’s listed company affiliation is Alcon, Inc. The patent focuses on a practical safety-checking technique for laser diodes in ophthalmic surgical apparatus, using operating conditions and measured output to assess performance.

Collaborations

The patent lists Ronald T. Smith and Alireza Mirsepassi among Liu’s coworkers. Their association reflects a collaborative context for the disclosed ophthalmic laser safety technology.

Conclusion

Yuchao Liu’s patent describes a temperature-aware method for evaluating laser diode performance and signaling the outcome of a safety test in ophthalmic surgical equipment.
