Buried utility locators including a locator body and twelve antenna coils are disclosed.

Buried object locator apparatus including twelve nodes

Self-standing attachment devices for use with utility locator systems are disclosed. In one embodiment a self-standing attachment device includes a top assembly, three extendable legs coupled to the top assembly with a movable joint, and a bottom assembly, with the self-standing attachment device detachably coupleable to a locator of the system. A formed coupler in the top assembly allows for readily attaching and detaching the self-standing attachment device and the locator.

Self-standing multi-leg attachment devices for use with utility locators

Utility locators with various antenna configurations for detecting buried objects or otherwise inaccessible pipes and other conduits, cables, conductors and inserted transmitters are disclosed. In one embodiment, a locator includes a body with a mast and head unit, one or more dodecahedral antenna nodes coupled to or on or within the body, and a camera disposed on or within the body. The camera may be a still camera, a video camera, or both. The locator may also include one or more GPS sensors coupled to one or more GPS antennas.

Buried object locator with dodecahedral antenna configuration apparatus and methods

Apparatus, systems, and methods are disclosed for tracking movement over the ground or other surfaces using two or more spaced apart cameras and an associated processing element to detect ground features in images from the cameras and determine tracking parameters based on the position of the detected ground features in the images.

Ground tracking apparatus, systems, and methods

Buried utility locator systems, including a camera, for detecting buried utilities and determining information therefrom based on sensing electromagnetic emissions from the buried utilities are disclosed. Images and/or video captured by the camera are stored in association with the determined information in a non-transitory memory.

Magnetic sensing buried utility locator including a camera

Apparatus, systems, and methods are disclosed for utility locating with tracking of movement over the ground or other surfaces using a dodecahedral antenna array and a stereo-optical ground tracker having two or more spaced apart cameras and an associated processing element to detect ground features in images from the cameras and determine tracking parameters based on the position of the detected ground features.

Buried utility locator ground tracking apparatus, systems, and methods

Buried object locators including a locator body, an antenna node including twelve or more magnetic field antennas in a fixed position, and an electronic circuit coupled to the antenna node for generating information associated with hidden or buried utilities are disclosed.

Buried object locator apparatus and methods

Buried object locators including an omnidirectional antenna array and a gradient antenna array are disclosed. A locator display may include information associated with a buried object determined based on processing of both omnidirectional antenna array signals and gradient antenna array signals.

Utility locator apparatus and systems

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.

Multi-frequency locating systems and methods

Video inspection systems with moveable and dockable CCUs are disclosed. In one embodiment a video inspection system includes a tubular frame element, a camera control unit (CCU), and a docking apparatus mechanically coupled to the frame element so as to allow the CCU to rotate and/or be detached are attached via a user action.

Cable storage drum with moveable CCU docking apparatus

Portable locators for detecting buried objects and determining information therefrom based on sensing electromagnetic emissions are disclosed. In one implementation, a portable locator may include a magnetic field sensor array and associated signal processing circuitry to detect and determine information associated with the buried object, as well as a camera and image or video processing circuitry to process images or video received from the camera in conjunction with the buried object detection.

Antenna systems for receiving transmitted signals comprising at least a first tuned antenna disposed in a known relationship spatially with a second antenna, with the first tuned antenna electrically connected to the second antenna, are disclosed. The antenna system may be configured to allow the antennas to reliably discriminate between left-hand and right-hand polarized circular signals.

Dual antenna systems with variable polarization

A high-Q human-portable, battery-powered self-correcting tunable transmitter apparatus for inducing alternating currents in buried conductors to facilitate their location is disclosed.

Utility locating transmitter apparatus and methods

Antenna systems for receiving transmitted signals comprising at least a first tuned antenna disposed in a known relationship spatially with a second antenna, with the first tuned antenna electrically connected to the second antenna, are disclosed. The antenna system may be configured to allow the antennas to reliably discriminate between left-hand and right-hand circular signals.
