摘要： A locator for determining the location of a buried utility line from an offset position. The locator has a top peak antenna, a bottom peak antenna, and a null antenna. The locator is tilted until the null antenna is pointed directly at the utility line with the top and bottom peak antennas disposed in a locating plane that is substantially vertical and perpendicular to the line. The tilt angle of the locator and the direct distance between the locator and the utility is measured. The tilt angle and direct distance are used by the processor to determine the vertical and horizontal distances between the locator and the utility.

摘要： A metal detector system 30 for sensing target (e.g., metal) objects within soil or other strata includes a pickup head 36 carrying an excitation coil configured to generate an excitation signal to energize a target object 400 and uses a 2-D (e.g., planar, rectangular) array of pixel-receive coils configured within the pickup head to receive electro-magnetic energy from the energized target object. As the user moves the pickup head across the strata's surface, the pixel-receive coils sense relative motion between each pixel-receive coil and the energized target object, where motion is detectable as individually sensed changes in received signal levels among the pixel-receive coils. The metal detector system also includes a 2-D display 46 which depicts or visually represents the 2-D array of pixel-receive coils and generates a changing display of any sensed moving target object 60 in response to sensed changes in received signal levels among the pixel-receive coils.

摘要： An airborne electromagnetic survey system that monitors the dipole moment. A TDEM system includes a flexible transmitter loop and a receiver having three sensors with mutually perpendicular sensitive axes. In flight, mechanical and aerodynamic forces cause the transmitter loop to tilt and flex, which affects the direction and magnitude of the primary field dipole moment. The processing system measures the sign and amplitude of the primary field sensed by the receiver in each of its sensitive axes and calculates a vector which represents the orientation of the primary field in the receiver frame of reference at the receiver location. Using this vector, the processing system determines the orientation of the primary field dipole moment.

摘要： A portable locator and method for establishing the location of the cable line in a region which includes at least one generally straight electrically conductive cable line extending across the region from which cable line a locating signal includes a first arrangement for measuring a local flux intensity of the locating signal at a first above ground point within the region with the portable locator in a particular orientation at the first above ground point. A second arrangement uses the local flux intensity to establish a cable line angular orientation which limits the possible directions to the cable line relative to the particular orientation of the portable locator at the above ground point. A third arrangement uses the measured local flux intensity to establish an actual direction of the cable line that is selected from the possible directions based on certain characteristics of the locating signal.

摘要： A method is disclosed as part of an overall process in which a boring tool is moved through the ground within a given region along a particular path in an orientation which includes pitch. A locating signal is transmitted from the boring tool which signal exhibits a field defined forward point within a reference surface which field defined forward point is vertically above an inground forward point on the particular path through which the boring tool is likely to pass. The method establishes a predicted depth of the boring tool at the inground forward point by first identifying the field defined forward point. The signal strength of the locating signal is then measured at the field defined forward point as being representative of the depth of the boring tool at an inground upstream point which is the current location of the boring tool. With the boring tool at the upstream inground point, the pitch of the boring tool is determined. Using the measured signal strength and the determined pitch, the predicted depth of the boring tool is determined for the inground forward point based on the boring tool moving along an approximately straight path to the inground forward point.

摘要： A stable heli-borne vector platform capable of accepting a range of different sensors or instruments, particularly, but not exclusively, for the mapping and exploration of mountainous regions is described. The platform enables the arrangement of the sensors in three orthogonal directions, thus allowing the restitution of the resultant vector. The geographical referencing is provided by the use of a differential GPS receiver, whose antenna is installed on the main body of the platform. This platform distinguishes itself from its predecessors through the use of a lateral pulling axis, the use of a heavy weight placed underneath the main body, and by a perfectly symmetrical geometry in the direction of pull, thus ensuring perfect in-flight balance and stability.

摘要： A method for avoiding an inground obstacle at a known depth, using a steerable boring tool which transmits a dipole locating signal, said method comprising the steps of: positioning the boring tool in a first position at a forward distance to the obstacle; measuring a signal strength of said locating signal at a location above the inground obstacle which corresponds to a field defined forward point of the locating signal such that the signal strength is representative of the depth of the boring tool at said forward distance from the obstacle; with said boring tool at said first position, determining a pitch orientation of the boring tool; determining a predicted depth of the boring tool based on at least generally straight movement of the boring tool by said forward distance toward the inground obstacle, said signal strength and said pitch orientation; and based on the predicted depth of the boring tool and the known depth of the obstacle, steering the boring tool in a way that is intended to avoid the obstacle.
