Title: **Michael J Tweedy: A Pioneer in Fiber Optic Sensing Technology**

Introduction

Michael J Tweedy is an accomplished inventor based in Simi Valley, California, with a significant portfolio that includes nine patents. His innovative work primarily revolves around fiber optic technology, particularly in the field of sensing applications.

Latest Patents

Among his latest patents are two noteworthy inventions that showcase his expertise. The first patent involves a **low-cost fiber optic velocity sensor for sonar applications**. This invention features a fiber optic sensor with a unique housing design that incorporates a flexural disk. The flexural disk is ingeniously constructed with a stepped thickness which facilitates effective isolation of the response to axial acceleration. The invention utilizes two fiber optic coils optically coupled through a fiber optic coupler, enabling the creation of an interferometer that generates an output signal indicative of axial acceleration.

The second patent describes a **method and apparatus for measuring acceleration using a fiber optic accelerometer**. This system cleverly utilizes a pair of fiber optic coils situated around a cylindrical, deformable support structure. As acceleration is applied, the structure alters from a cylindrical to a conical shape, causing differential expansion and contraction of the fiber optic coils. This interaction results in a detectable phase difference in light signals, providing accurate measurements of acceleration along the sensing axis.
