Title: Innovations of John F DeMartini

Introduction

John F DeMartini is a notable inventor based in Lake Mary, FL (US). He holds a total of 4 patents that showcase his contributions to the field of turbine technology. His work primarily focuses on methods for monitoring turbine blade vibrations and ensuring the accuracy of turbine blade positioning.

Latest Patents

One of his latest patents is titled "Method of on-line turbine blade slope and sensor position verification." This invention involves a method for monitoring vibrations in a turbine blade structure. It includes generating signals from a sensor located adjacent to the radial outer edge of the blade structure to sense the passage of targets on the blade. The sensor is mounted eccentrically, and signals are obtained with the sensor positioned at different angular locations. The first aspect of this invention allows for the determination of a target slope angle on a turbine blade during operation. The second aspect enables the sensor to adjust its position in response to variations in the axial position of the target.

Another significant patent is the "Microwave system for monitoring turbine blade vibration." This method involves transmitting a continuous wave of microwave energy toward a rotating row of turbine blades. Each passage of an individual blade tip through the path of the continuous wave generates a signal that indicates the timing of each passage. This signal is then monitored and analyzed to detect blade vibrations, utilizing either a standing wave or a reflected wave.
