Title: The Innovations of Nesco Mario Lettsome, Jr.
Introduction
Nesco Mario Lettsome, Jr. is an accomplished inventor based in Beltsville, MD (US). He has made significant contributions to the field of magnetometry, particularly with his innovative patent that enhances the capabilities of RF magnetometers. His work is characterized by a focus on overcoming technical limitations and improving measurement accuracy.
Latest Patents
Lettsome holds a patent for a "DC SQUID based RF magnetometer operating at a bandwidth of 200 MHz and higher." This invention addresses the frequency limitations associated with noise signals that arise due to transmission line delays between the SQUID circuit and readout electronics. By superimposing RF flux on the modulation flux, his design produces a binary phase modulated RF voltage at the SQUID output. This voltage is processed to lock the static flux and control the modulation regime by generating an AC bias for the RF flux. The RF readout electronics utilize a double lock-in technique, which allows for a signal proportional to the product of amplitude and phase cosine of RF flux, achieving a linear dynamic range up to five orders of magnitude compared to traditional DC SQUIDs.
