摘要： A balanced field metal detector apparatus comprising a coil assembly including planar, generally rectangular loop configured multi-turn field and sensor coils disposed in partially overlapping minimum mutual inductive coupling relation and oriented so that the long dimension of the loops is skewed relative to the vertical in use of the apparatus. Employment of a pair of the detectors, one on each side of a pathway, with the respective coil assemblies skewed relative to the vertical oppositely to one another, enables detection of a metal object in the pathway by one or both of the detectors irrespective of the shape and orientation of the object, and by suitable processing of the sensor coil signals further enables determination of whether the object is located at the left, center or right side of the pathway.

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： In a method and system for monitoring an underground cable in a site of interest, multiple samples of magnetic field data and corresponding location data are collected periodically over a sampling period of extended time. The magnetic field data samples and corresponding location data are processed to determine respective topologies of one or more current-carrying conductors in the site and for each of the conductors respective magnetic field data relating to each sampled point are integrated with respect to a predetermined parameter of the respective conductor so as compute an integrated contribution of each sampled span along the respective conductor. The data relating to different conductors in the site are output in a manner that allows determination of a conductor for which the parameter changes during the sampling period.

摘要： A method is described for use with first and second in-ground cables such that, when the first cable is driven at a locating signal frequency to emit a locating signal in an electromagnetic form, the locating signal can be coupled to the second cable to cause the second cable to generate a false locating signal. The method includes generating the locating signal frequency. A reference signal is produced. The locating signal frequency is impressed on the reference signal in a way which provides for distinguishing between the locating signal and the false locating signal. The locating signal frequency and the reference signal are summed to produce a summer output. The summer output is coupled onto the first cable such that the first cable emanates the locating signal and the reference signal, and the reference signal can be received for distinguishing between the locating signal and the false locating signal.

摘要： At least one antenna array including three mutually orthogonal antennas each sharing a common center point senses an electromagnetic signal emitted by a buried object such as a utility line, pipe or sonde. A circuit at least partially mounted in a housing is connected to the array and determines a location of the buried object by measuring signal strength and field angles in three dimensions without having to align the antenna array relative to the buried object while eliminating nulls and false peaks. A graphical user interface (GUI) has user-friendly icons, symbols, menus, numbers and graphical and auditory representation of signal strength. A SEARCH view indicates signal strength by showing a rotating strength indicator, a trace mode MAP view in which line location is shown by a line that moves side-to-side, and a sonde mode MAP view in which sonde location is shown by a moving line, pole and equator.
