Patent Images
1. A method for use in a buried object locator system, comprising:
- generating, at a buried object transmitter, one or more output signals including a plurality of signal components at ones of a plurality of different output frequencies;
coupling the one or more output signals from the transmitter to a buried object in the ground to generate a buried object current;
receiving, at a buried object locator, radiated signal components associated with the buried object current at a plurality of the different output frequencies; and
determining, at the buried object locator, information associated with the buried object based on two or more of the radiated signal components.

Abstract
Multi-frequency buried object location system transmitters and locators are disclosed. A transmitter may generate and provide output signals to a buried object at a plurality of frequencies, which may be selected based on a connection type. Corresponding locators may simultaneously receive a plurality of magnetic field signals emitted from the buried object and generate visual and/or audible output information based at least in part on the plurality of received magnetic field signals. The visual and/or audible output may be further based on signals received from a quad-gradient antenna array.
