Tri-Pod Buried Locator System
First Claim
1. A human-portable self-standing locator system for locating a buried object characterized by an electromagnetic (EM) field emission, the system comprising:
- at least three foldable support elements adapted to support the locator system on a substantially horizontal surface;
within at least one of the foldable support elements, an EM sensor array;
a gradient processing circuit coupled to the EM sensor array for producing a signal representing the B-field gradient at the EM sensor array as a function of time within at least one frequency band;
a locator processor coupled to the gradient processing circuit for producing signals representing target locations responsive to signals accepted from the gradient processing circuit;
an accessory mounting interface coupled to the locator processor and disposed to accept temporary attachment of an accessory sensor system;
a user interface coupled to the locator processor for accepting user commands and for indicating the buried object location relative to the locator system.

Abstract
A portable self-standing electromagnetic (EM) field sensing locator system with attachments for finding and mapping buried objects such as utilities and with intuitive graphical user interface (GUI) displays. Accessories include a ground penetrating radar (GPR) system with a rotating Tx/Rx antenna assembly, a leak detection system, a multi-probe voltage mapping system, a man-portable laser-range finder system with embedded dipole beacon and other detachable accessory sensor systems are accepted for attachment to the locator system for simultaneous operation in cooperation with the basic locator system. The integration of the locator system with one or more additional devices, such as fault-finding, geophones and conductance sensors, facilitates the rapid detection and localization of many different types of buried objects.
