摘要： A boring tool is moved through the ground within a region along a path from a starting point. A reference path is established. An information generating arrangement is located partially at the boring tool and partially at the locator including a transmitter for transmitting an electromagnetic signal from the boring tool and a receiver in the portable locator to generate certain information about the position of the boring tool relative to the position of the locator. The boring tool is moved in cooperation with the locator to establish a series of boring tool locations on the particular path such that each boring tool location is associated with one of a series of associated reference points on the reference path. An actual path of the boring tool is established which actual path corresponds to a particular path taken by the boring tool and a record is saved.

摘要： When a first cable is driven at a locating signal frequency to emit a locating signal, the locating signal can be coupled to a second cable to cause the second cable to generate a false locating signal. As part of discriminating the false signal from the locating signal, the locating signal is generated at the locating signal frequency and phase shifted to produce a phase shifted locating signal frequency. A reference signal is impressed with the phase shifted locating signal frequency. A coupling configuration couples the locating signal frequency onto the first cable to generate the locating signal subject to a coupling configuration phase shift. The phase shifted locating signal, as part of the reference signal, can compensate for the coupling configuration phase shift in the locating signal as emitted by the first cable.

摘要： A detector for detecting a buried current carrying conductor includes a digital signal processor, magnetic sensors, and a power supply unit. The power supply unit is a switched mode power supply which incorporates a proportional integral differential controller feedback algorithm and which is managed by the digital signal processor. The load and source voltage are monitored by the digital signal processor and a look-up table is used to control a pulse width modulator, which drives a single ended primary induction controller. The digital signal processor processes and compares signals received from the sensors to calculate a depth of a buried conductor. The self-generated noise of the power supply unit does not interfere with the frequency bands of detection of the detector.
