Title: Innovations of Eric D Park

Introduction

Eric D Park is an accomplished inventor based in Blacksburg, VA (US). He has made significant contributions to the field of fiber optics, holding a total of 2 patents. His work focuses on developing advanced sensing technologies that enhance the capabilities of fiber optic systems.

Latest Patents

One of his latest patents is for a fiber optic fluid sensor using a coated sensor tip. This innovative optical fluid sensing apparatus features a sensing tip with a conical configuration and a coating, such as a thin layer of polytetrafluoroethylene (PTFE). The design allows emitted light to be refracted back into a detector fiber optic cable or lost, depending on the relationship between the indices of refraction of the sensing tip and the surrounding substance. The careful selection of the index of refraction and bevel angle ensures accurate sensing of fluids. When fluid surrounds the tip, light is dispersed and lost, while in the absence of fluid, the coating sheds any remaining liquid, allowing light to be internally reflected back into the detector.

Another notable patent is an error detection system for two-state fiber optic sensors. This system samples an amplified photodetector signal using various detectors, including an ON-OFF threshold detector and a slope detector. The ON-OFF threshold detector monitors the signal to activate the appropriate sensor output, while the disconnect threshold detector triggers an error signal if the signal falls below a certain threshold. The slope detector monitors rapid changes in the signal, allowing for accurate detection and error signaling when discrepancies arise.
