Title: Innovations of Narendra K Batra
Introduction
Narendra K Batra is an accomplished inventor based in Springfield, VA (US). He has made significant contributions to the field of ultrasonic measurement technologies, holding a total of 3 patents. His work focuses on innovative methods for measuring coating thickness and inspecting submerged surfaces for corrosion.
Latest Patents
One of his latest patents is titled "Method for measuring coating thickness using ultrasonic spectral tracking." This invention provides a method and apparatus for measuring the thickness of a coating material using ultrasonic signals. A broad band of frequencies is transmitted by a transducer towards a coating layer on a substrate, and a trailing signal is received from the coating layer/substrate interface while a leading backscattered signal from a fluid/coating layer is gated out. The trailing signal is deconvolved into a set of frequencies, and the resonant frequency of the coating layer is determined as the frequency with the greatest amplitude. The thickness of the material is then calculated as a function of the resonant frequency of the coating layer.
Another notable patent is "Method and apparatus for in situ measurements of corrosion of submerged surfaces." This invention includes an apparatus for inspecting the base of a liquid-filled tank for corrosion. It features a housing for use in the tank, a set of ultrasonic transducers for directing ultrasonic pulses at the base, and a data capturing system for storing information from the return signals. The method involves directing a broadband ultrasonic pulse at the base, receiving a return signal, performing a Fourier analysis on the return signal, and determining the thickness of the base from the frequency domain signal.
