Publication number: 20100243326Abstract: A system and method of interfacing a drilling machine with one of a number of different walk-over guidance systems involves receiving an ID signal from a particular walk-over guidance system selected for use with the drilling machine. A protocol library associated with the particular walk-over guidance system is accessed in response to the ID signal. The protocol library is used to effect communication between the particular walk-over guidance system and a control system of the drilling machine during cooperative use of the particular walk-over guidance system and drilling machine. Using the protocol library involves converting, as prescribed by the protocol library, locator signals received from the particular walk-over guidance system from a locator protocol to a common protocol used by the control system of the drilling machine. Locator and drilling machine data of various types can be presented to a drilling machine operator via an on-board display.Type: ApplicationFiled: June 11, 2010Publication date: September 30, 2010Inventors: Jeremy Jin, Scott Rempe

Patent number: 7663373Abstract: A method and system for identifying a location of a magnetic field source. A total magnetic field is measured during a calibration routine prior to a drilling procedure. During the drilling procedure, a magnetic field measurement is obtained. Using a ratio of the measured magnetic field and the calibrated field, a set of possible angles and distances is calculated. After the source is advanced a known distance, a second magnetic field measurement is obtained. A second ratio is calculated and a second set of possible angles and distances is calculated. The relative location of the source is then determined using the first set and second set of values, along with the known distance and a pitch angle of the source.Type: GrantFiled: December 17, 2007Date of Patent: February 16, 2010Assignee: The Charles Machine Works, Inc.Inventors: Michael F. Gard, Kody D. Mason, Floyd R. Gunsaulis

Patent number: 7579962Abstract: A duct mapping tool comprises a sonde for transmitting a locate signal detectable above the ground and locomotion means for providing movement through the underground duct. A user above the ground detects the transmitted location signal using a signal receiver, and maps the location of the underground duct. In one embodiment, a GPS receiver generates location data at locations associated with the received location signal. The GPS generated location data may be used in conjunction with appropriate mapping software to generate street level maps of underground ducts. Locomotion can be provided in a variety of ways, such as a flexible rod attached to the duct mapping tool and operated by a technician, air motors, or electric motors.
