Location systems and methods for locating paint and other markings on a surface are disclosed. A paint marking stick may include a magnetic field sonde that is actuated in conjunction with dispensing of paint or other markers, where the sonde generates a magnetic field signal in conjunction with dispensing of paint or placement of a marker. A corresponding utility locator may receive the sonde magnetic field dipole signal and determine and store positional information and type information associated with the paint or other marker.

Trackable dipole devices, methods, and systems

Cable storage drum-reel and cable guide apparatus, methods, and systems are provided for deploying and retracting at least one push-cable with a distally mounted camera into and out of a pipe or cavity for applications such as plumbing and underground utility location. In an exemplary embodiment, a cable guide assembly may include a bracket, and one or more wear guides positioned with openings in the bracket. The one or more wear guides may include two spaced-apart wear guides each having an opening defining an inner diameter. In one embodiment, the spacing between the two wear guides may be a distance of three or more times the inner diameter of the wear guides.

Inspection system push-cable guide apparatus

Pipe inspection systems including a push-cable, jetter, and camera assembly are disclosed. A jetter nozzle may be configured to spin and/or propel the camera head within a pipe or other cavity. A cutter line may be attached to the camera head to clean obstructions. A sonde may be coupled to a camera head to generate magnetic field signals for use with a buried utility locator to locate a pipe or other cavity into which the camera head is deployed.

Pipe inspection and cleaning apparatus and systems

A novel connection port is described for connecting a signal transmitter to an apparatus configured to wirelessly communicate video and images from a pipe inspection system. Such a connection port may establish an electrically conductive pathway to a push-cable and camera head further disposed in cable storage drum that the wireless communication apparatus may couple thereto. A signal transmitter, having an established electrically conductive pathway to the push-cable and camera head, may transmit electromagnetic signals that may be emitted by the push-cable and camera head and further be located at the ground surface via a utility locator device.

Video inspection system apparatus and methods with relay modules and connection ports

A pipe inspection system includes a cable storage drum and a housing configured to removably receive and rotatably support the cable storage drum. A push-cable with a plurality of conductors is stored in the drum. An inspection camera may be attached to a distal end of the push-cable. The drum includes a hollow core outer cone configured to accept an inner core removable module. The removable module may include electrical, mechanical, wireless, satellite, and power/battery interfaces. The module mates with a contact plate sealed inside the inner cone. The inner core components, including the battery module, are stationary relative to the inner core. The inner core is free to rotate bidirectionally inside the outer cone as the camera is being fed into, and out of a pipe or conduit for inspection. Slip-rings are not required to maintain connectivity because the electronics and battery module are stationary relative to each other.

Inner drum module with push-cable interface for pipe inspection

The present disclosure relates to combined antenna apparatus for receiving GNSS signals and other radio signals to mitigate cross-coupling.

Combined satellite navigation and radio transceiver antenna devices

The present application relates to PPP-RTK, RTK, SSR, or like correction data based devices and methods to produce geolocation solutions with improved accuracy. Further, such devices and methods may be further employed in various related utility locator devices, utility locating transmitters, and other utility locating and mapping devices.

GNSS positioning methods and devices using PPP-RTK, RTK, SSR, or like correction data

Systems and methods for annotating, also known as tagging, visually identifiable objects using natural language (i.e. spoken voice) are provided. More specifically, but not exclusively, this disclosure relates to systems and methods for tagging identified objects related to underground utilities and assets, and communication systems. Once tagged, data representing identified objects can be stored, transmitted, and/or mapped. In an exemplary embodiment, a utility service worker or other personnel may walk or drive around an area of interest using utility locating equipment or systems to collect data. As data is being collected, the user may visually identify utility related or other items using a laser pointer, and then use their voice to tag items of interest. A headset including a microphone may be provided for capturing the user's voice. Hardware and/or software may be provided for processing tagged items, and relating them to a specific location, and/or utility asset.

Natural voice utility asset annotation system

A video pipe inspection system may include a push-cable, camera head, and/or pipe guide.

Video pipe inspection systems

Coaxial video push-cables are disclosed. One embodiment includes a central conductor and a multi-dielectric stack of multiple concentric tubular layers disposed around the central conductor having one or more structural layers and one or more impedance tuning layers where the thickness of materials of each layer are selected to provide a pre-defined elastic modulus and electromagnetic impedance, an electromagnetic shielding layer, and a jacket enclosing the shielding layer, multi-dielectric stack layers, and central conductor.

Multi-dielectric coaxial push-cables and associated apparatus

Buried utility transmitters and associated locator devices, systems, and methods used for locating utility lines, pipes, and/or other conductors that are obscured from view are disclosed.

Utility locator transmitter devices, systems, and methods

Video inspection systems are disclosed. In one embodiment a video camera for use in a pipe inspection system includes a camera head including an outer housing, a camera module assembly including video and non-video sensors, a processing circuit, and a data link receiver.

Video pipe inspection systems and methods with sensor data

Front end circuits and associated apparatus, systems, and methods for use in electronic devices such as buried utility locators are disclosed. The circuits include receivers and filters on input signals that are coupled to ground rather than differentially. A multiplexing circuit allows shared use of amplifiers, and analog-to-digital converters via a switching mechanism for selectively making or breaking electrical connection to the receiver channels for efficient sharing of electronics resources while minimizing crosstalk interference and advantageously reducing costs.

Input multiplexed signal processing apparatus and methods

Omnidirectional electromagnetic signal inducer (omni-inducer) devices are disclosed. The omni-inducer device may include a housing, which may include a conductive base for coupling signals to ground, and an omnidirectional antenna node including a plurality of antenna coil assemblies, where the node may be disposed on or within the housing. The omni-inducer device may further include one or more transmitter modules for generating ones of a plurality of output signals, which may be generated at ones of a plurality of different frequencies, and one or more control circuits configured to control the transmitters and/or other circuits to selectively switch the ones of the plurality of output signals between ones of the plurality of antenna coil assemblies.

Omni-inducer

Sonde devices for providing magnetic field signals for use with utility locators or other devices are disclosed. In one embodiment a sonde device includes a housing, a core comprising a plurality of core sections, and one or more support structures, which may include windings. Circuit and/or power supply elements may be disposed fully or partially within the core to control generation of predefined magnetic field frequencies and waveforms.
