Title: **Innovator Spotlight: Sonja M. Hansen - Advancing Underground Detection Technologies**

Introduction

Sonja M. Hansen is an accomplished inventor based in Carmichael, California, known for her significant contributions to underground detection systems. With 2 patents to her name, she has made strides in enhancing safety and efficiency in the detection of lead and leaks within underground infrastructure.

Latest Patents

Hansen's latest innovations include a **lead detection system for underground pipes** and a **leak detection system for underground access chambers using conductivity**. The lead detection system utilizes a probe that forms an electrically conductive path between a ground stake and the probe itself. This system enables the detection of lead in underground pipes by analyzing the current flow through the circuit, which reflects the electrical conductivity of the pipe material.

Her second invention, the leak detection system, employs an electrically conductive probe positioned adjacent to the walls of underground access chambers. This system effectively detects leaks by adjusting the probe's position to scan various wall regions. One variation of the probe features whiskers that extend radially, allowing for improved leak identification through the measurement of conductivity variation associated with leaks.
