摘要： A self-tuning resonator for use in a transmitter apparatus for inducing alternating currents in a buried conductor. The resonator is dynamically tuned at frequencies below 500 kHz by exploiting the inherent voltage-variability of net capacitance in multilayer ceramic capacitors. The transmitter apparatus provides improved efficiency and induced output power suitable for use in a man-portable locator system, providing a very high magnetic field output from a physically small battery-powered resonator at frequencies under 500 kHz. The resonator exhibits a very low equivalent series resistance (ESR) and is adaptively returned to a predetermined resonant frequency responsive to any changes in resonance arising from phenomena such as component heating, thereby supporting very high tank circuit currents from battery-powered source to produce very high magnetic flux output.

摘要： A blind locating system for finding and tracing buried objects such as utility lines, conductive pipes and sondes. A sensor array is coupled to a signal processor, which determines a field vector for one or more buried objects by producing a data signal representing a covariance matrix corresponding to the covariances of the time-varying sensor array signals over a selected frequency band and accumulation interval. The covariance matrix is characterized by eigenvalues and associated eigenvectors and a user interface (UI) indicates the field vector associated with the eigenvector having the largest eigenvalue. Using several different frequency bands, a plurality of underground objects may be simultaneously detected and indicated in the UI without foreknowledge of their existence or characteristics.

摘要： A human-portable utility locator system for locating and tracing a buried utility line characterized by an electromagnetic field emission. The locator may include a horizontal spaced sensor pair for detecting the horizontal field asymmetry of the emitted field in one or more independent frequency bands, which is employed to assist in determining an accurate “virtual depth” measurement for producing detection events. An event detector may be disposed to detect events corresponding to extremum in the B-field gradient with respect to time and a user interface (UI) coupled to the event detector signals the detected event to a user. In a preferred embodiment, one pair of spaced-apart 3D magnetic sensor arrays is disposed substantially orthogonal to another intermediate spaced-apart pair of sensors.
