Abstract: A method for locating buried utilities in a utility locator is disclosed. The method may include receiving, at an antenna array for receiving magnetic field signals, a plurality of magnetic field signals at predefined signal frequencies in a predefined frequency suite, generating, in a receiver coupled to an output of the antenna array, a first receiver output signal, generating, in a processing element coupled to the receiver, a first set of data associated with the two or more signal components, and storing, in a non-transitory memory of the locator, the first set of data.

Abstract: The present disclosure is directed to vehicle-based systems for locating and mapping buried utility lines using principal components. Vehicle-based utility locating devices receive magnetic field signals emitted by utility lines and, with determined position data, implement principal component analysis to locate and map the utility lines.

Abstract: Systems, devices, and methods for locating buried conductors using ambient electromagnetic signals, such as AM or other broadcast signals, are described. A buried utility locator may include a plurality of spatially separated antenna arrays, a receiver circuit coupled thereto, and a processing element programmed to process measurements of ambient electromagnetic signals and associated electromagnetic signals radiated from current induced in the buried conductor from the ambient signals to determine information about the buried conductor.

Abstract: A buried utility locator includes an antenna array for receiving magnetic field signals from a buried utility, a receiver operatively coupled to the antenna array for generating a receiver output signal including amplitude and/or phase information of two or more signal components in two or more simultaneously received signals of the frequency suite, a processing element operatively coupled to the receiver for receiving the receiver output signal and generating a first set of data associated with the two or more signal components of the frequency suite, and a non-transitory memory for storing the first set of data.

Abstract: Mobile base stations for use with one or more portable utility locators to aid in determining the location of a particular locator during operation and to receive information associated with the utility for storage and/or retransmission to other devices or systems are disclosed.

Abstract: This disclosure is directed to utility locating systems, devices, and methods using frequency suites of simultaneously processed signals emitted from buried utilities to locate the buried utilities or other hidden or buried conductors.

Abstract: A locator system for locating buried utilities such as conduits, cables, pipes or wires incorporates image-capturing and position and orientation measuring devices such as magnetic compass, accelerometers, gyros, GPS, and DGPS. The system may include other sensors such as gas concentration sensors. The system associates images captured during the locate process with buried utility position data and the other sensor data. These data and images may be further associated with terrain images from satellites or aerial photography to provide a highly precision map and database of buried utility locations and visual images of the burial site. Information so obtained may be transferred to a hand-held personal communication device (such as a smart phone) capable of displaying an augmented or virtual reality display showing the location of buried utilities in combination with photo-images and/or terrain maps.
