摘要： 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.

摘要： Magnetic locators and uses of such locators for detection of buried utilities are disclosed. Outputs provided from two or more three three-axis magnetic sensors based on magnetic field signals sensed at single points in space in three axes may be used to determine information about the buried utilities including position and/or depth of the buried utilities relative to the locator.

摘要： Systems for locating hidden utilities including a portable locator and associated portable transmitter are disclosed. The portable locator may include a magnetic field measurement module for determining a current signal in the hidden utility based on a received magnetic field, and a receiver module for receiving data from the portable transmitter. The portable transmitter may include a data transmitter module for wirelessly sending information associated with a current signal provided to the hidden utility to the portable receiver module. The portable receiver may be configured to measure a relative change in magnetic field angles, and determine an amount of cross coupling to adjacent utilities based at least in part on the measured magnetic field angles.

摘要： 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.

摘要： Multi-frequency buried object location system transmitters and locators are disclosed. A transmitter may generate and provide output signals to a buried object at a plurality of frequencies, which may be selected based on a connection type. Corresponding locators may simultaneously receive a plurality of magnetic field signals emitted from the buried object and generate visual and/or audible output information based at least in part on the plurality of received magnetic field signals. The visual and/or audible output may be further based on signals received from a quad-gradient antenna array.
