Title: Innovations of Elizabeth V Stein

Introduction

Elizabeth V Stein is a prominent inventor based in Ft. Lauderdale, FL (US). She has made significant contributions to the field of technology, particularly in the area of sensors and turbopump systems. With a total of 6 patents to her name, her work has garnered attention for its innovative approaches to detecting hydrocarbons and cavitation.

Latest Patents

One of her latest patents is a sensor for detecting hydrocarbons in a seal. This hydrocarbon presence sensor is designed to detect fuel in a buffer cavity of an inter-propellant seal. The sensor is formed on a rotor shaft within the buffer cavity, utilizing an optical imaging device to observe changes in appearance when hydrocarbons form on its surface. The sensor can be made from either an oil/fuel leak detection powder or an oil colorimetric developer. A light source, either white light or a laser, is reflected off the sensor, and the optical imaging device reads the reflected light to identify any changes in color or intensity, indicating the presence of hydrocarbons.

Another notable patent is for a turbopump with cavitation detection. This cryogenic turbo-pump features an inducer and a system for detecting the onset of cavitation at the blade tips of the inducer. An infrared imaging sensor is employed to monitor the blade tips during the turbo-pump's operation, looking for a temperature drop that signifies the onset of cavitation. The imaging sensor is designed to vary the image capture rate, allowing the rotating blade tip to appear stationary for accurate temperature measurement. A window in the inducer housing enables the imaging sensor to view the blade tips during operation.
