Title: Edson Ferreira: Innovator in Acoustic Ranging Systems

Introduction

Edson Ferreira is a notable inventor based in Peterborough, Canada. He has made significant contributions to the field of acoustic ranging systems, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

One of his latest patents is titled "Method for determining an echo distance in an acoustic pulse-echo ranging system." This method allows for the direct use of a digitized raw echo signal for correlation-based echo distance estimation. The process involves transmitting an acoustic pulse with a carrier frequency, providing a digital expected echo shape with high time resolution, and receiving and digitizing the echo. Correlation values are created from the digitized echo and the expected shape, which are then weighted to determine the echo distance from the center of mass of the weighted values.

Another significant patent is the "Power decoupling circuit for loop powered time-of-flight ranging systems." This invention pertains to a power decoupling circuit for a time-of-flight ranging or level measurement system that operates on a current loop. The system includes a loop current regulator that regulates the current to transmit level measurement data. The power decoupling circuit features a feedback circuit and a step-up converter, which provides charging current to an energy storage device for the transducer, optimizing power for measurement.
