Title: Leland Gilreath: Innovator in Digital Radiometric Systems

Introduction

Leland Gilreath is a notable inventor based in Newport Beach, CA (US). He has made significant contributions to the field of digital radiometric systems, showcasing his expertise through his innovative patent.

Latest Patents

Leland holds a patent for a Delta-sigma digital radiometric system. This passive radiometric system is designed for thermally imaging objects in a scene. The system features a digital square-law quantizer circuit that includes multiple comparators and a voltage divider network with several resistors. Each comparator receives a distinct reference signal generated by the voltage divider network and a common power signal from an antenna, outputting a high or low digital bit signal. Additionally, the system incorporates a delta-sigma circuit with a weighting table that responds to the digital bit signals from the comparators, converting them into a normalized bit word. The delta-sigma circuit also contains an accumulator that averages the digital bit words, while a digital-to-analog converter transforms the averaged bit words into an analog signal, which serves as feedback to the quantizer circuit.
