Publication number: 20040045739Abstract: A portable mapping tool for use in a horizontal drilling system and associated methods use a boring tool configured for transmitting a locating signal. The mapping tool also includes at least one electromagnetic field detector which is configured for measuring the locating signal from a fixed position proximate to the surface of the ground in a drilling area. The mapping tool includes a housing and a transmitter arrangement supported by the housing for transmitting a setup locating signal for reception by the detector in the region for use in determining certain initial conditions at least prior to drilling. The associated methods include the step of configuring the mapping tool for transmitting a setup locating signal for reception by the detector in the region and using the received setup locating signal in determining certain initial conditions at least prior to drilling.Type: ApplicationFiled: September 4, 2003Publication date: March 11, 2004Inventors: John E. Mercer, Peter H. Hambling, Rudolf Zeller, Shiu S. Ng, Guenter W. Brune, Lloyd A. Moore

Patent number: 6668944Abstract: Specific methods are described for use in tracking and/or guiding the movement of an underground boring tool. In one aspect, an improvement is provided forming part of an arrangement for tracking the position and/or guiding the boring tool using an electromagnetic locating signal which is transmitted from the boring tool as the boring tool moves through the ground. At least two detectors are located at fixed positions within the region, each being operable in a transmit mode and in a receive mode such that each one of the detectors in the transmit mode is able to transmit a relative locating signal to the other detector for use in determining the relative position of one detector in relation to the other and such that both detectors receive the electromagnetic locating signal in the receive mode for use in determining the position of the boring tool within the region.Type: GrantFiled: January 28, 2003Date of Patent: December 30, 2003Assignee: Merlin Technology, Inc.Inventors: Guenter W. Brune, Peter H. Hambling, John E. Mercer, Lloyd A. Moore, Shiu S. Ng, Rudolf Zeller

Patent number: 6454023Abstract: Systems and associated methods for tracking and/or guiding an underground boring tool use one or more detectors to measure the intensity of an electromagnetic field which is transmitted from an underground boring tool. The measured intensities may then be used to determine the location of the boring tool. In a dead reckoning embodiment of the invention, one detector may be employed while, in a position determination embodiment, two or more detectors may be employed. In any embodiment, physically measurable parameters may be used in addition to measured magnetic intensities. A highly advantageous mapping tool instrument for use in the position determination embodiment and a cubic antenna for use in any magnetic field detector are employed herein.Type: GrantFiled: June 15, 2000Date of Patent: September 24, 2002Assignee: Digital Control IncorporatedInventors: John E.
