Title: John J Kidwell: Innovator in Optical Sensor Technology
Introduction
John J Kidwell is a notable inventor based in Louisville, OH (US). He has made significant contributions to the field of optical sensor technology, holding a total of 3 patents. His work focuses on innovative solutions for measuring angular or rotational positions using optical fibers.
Latest Patents
One of Kidwell's latest patents is for optical rotary microbend position sensors. This invention utilizes a single optical fiber to measure angular or rotational position in a rotary sensor. The optical fiber is integrated with known analog intensity opto-electronics and is housed within a microbending device. The input shaft of the sensor experiences rotational motion, which causes the microbending device to subject the optical fiber to microbending. This microbending can be induced by various mechanisms, such as a crankpin or pins located on the shaft. Additionally, a micrometer lead screw can convert the rotational motion into linear motion, which is then used to compress the optical fiber. The changes in the fiber radius of curvature due to microbending are measured by the opto-electronics or photodetection arrangements.
Another significant patent by Kidwell is a fiber optic displacement sensor using a fiber optic coil. This sensor employs a resilient coil with an optical fiber positioned within it. The coil has a predetermined length and pitch, and an optical signal is applied to the optical fiber. Any movement of the coil modulates the optical signal transmitted along the optical fiber, allowing for precise measurements of various parameters.
