Abstract:
Docking stations and docking methods are provided for use with marking devices used for marking the presence or absence of an underground facility in a dig area. The docking station may serve as a home base for storage of a marking device, for charging the battery of a marking device, for transferring data to and from a marking device, and for securing a marking device against unauthorized use and/or theft. The docking station may be a mobile docking station that is installed in a vehicle or may be a fixed docking station that is installed at a central location in the field, at a central office, at a home base facility, and the like.
Abstract:
A marking device for a marking operation to mark a presence of an absence of one or more underground facilities is configured to access and display facilities map information, and/or other image information, as a visual aid to facilitate the marking operation. In various aspects, methods and apparatus relate to: selection of an “base” facilities map, or information from a database of facilities map data, relating to a given work side/dig area; selection of an pan and/or zoom (resolution) for displaying facilities map information; updating displayed facilities map information while a marking device is used during a marking operation (e.g. changing pan, zoom and/or orientation); overlaying on the displayed facilities map information marking information and/or landmark information relating to the marking operation; and storing locally on the marking device, and/or transmitting from the marking device, facilities map information and/or overlaid marking/landmark information (e.g., for further processing, analysis and/or subsequent display).
Abstract:
A locate receiver to detect an underground facility includes an RF antenna to receive a magnetic field and provide an output signal based on the received magnetic field, and a processing circuit for determining a magnetic field strength of the magnetic field based on the output signal. The locate receiver also includes a display device, a memory and a processor. A map image based on facilities map data is displayed on the display device. The processor compares a first location at which an indication of detection of the underground facility is generated to a second location of a facility line as indicated by the first map data, and generates an alert based on a disagreement between the first location and the second location.
Abstract:
A positive response notification to provide information regarding locate and/or marking operations for underground facilities may include time-stamp information to provide proof of a time at which the locate and/or marking operation was completed by a locate technician, and/or place-stamp information to provide proof of a presence of the locate technician at or near a work site. An electronic manifest image and/or a virtual white line image similarly may be included in a positive response notification. In one example, such images may be bundled together based on respective descriptor files (or descriptor metadata) that associates the corresponding images with a locate request ticket for the operation. In another example, a positive response notification may include environmental information regarding one or more environmental conditions present at or near the work site during the locate and/or marking operation.
Abstract:
A technician performs a locate operation of an underground utility in a dig area of proposed excavation by applying one or more physical colored markers (e.g., paint, flags, other colored markers) to ground, pavement or other surface to indicate a presence or an absence of the underground utility in the dig area. A digital image of a geographic area comprising the dig area is displayed on a display device, and one or more electronic colored markers corresponding to the physical colored marker(s) are added to the displayed digital image so as to generate a marked-up image. Information relating to the marked-up image is electronically transmitted and/or electronically stored so as to document the locate operation.
Abstract:
A marking device for a marking operation to mark a presence or an absence of one or more underground facilities is configured to access and display facilities map information, and/or other image information, as a visual aid to facilitate the marking operation. In various aspects, methods and apparatus relate to: selection of an appropriate “base” facilities map, or information from a database of facilities map data, relating to a given work site/dig area; selection of an appropriate pan and/or zoom (resolution) for displaying facilities map information; appropriately updating displayed facilities map information while a marking device is used during a marking operation (e.g. changing pan, zoom and/or orientation); overlaying on the displayed facilities map information marking information and/or landmark information relating to the marking operation; and storing locally on the marking device, and/or transmitting from the marking device, facilities map information and/or overlaid marking/landmark information (e.g., for further processing, analysis and/or subsequent display). In one aspect, a location at which marking material is dispensed is compared to a location of a facility line as indicated by the facilities map or other image information, and an alert may be generated based on the comparison.

Abstract:
Methods, apparatus, and systems for facilitating a marking operation to indicate a presence or an absence of at least one underground facility. Marking information relating to the marking operations, including one or both of environmental information representative of at least one environmental condition of an environment in which the marking operation is performed, and operating information representative of at least one operating condition of a marking device used to perform the marking operation, is electronically acquired. A marking material is dispensed to mark the presence or the absence of the at least one underground facility is dispensed, and the dispensing is controlled based at least in part on the acquired marking information.

Abstract:
Marking devices for dispensing markers on the ground and marking methods are provided. The marking devices and marking methods use a marking dispenser having a machine-readable ID mechanism. The ID mechanism has data storage capability. In one embodiment, the marking dispenser may be provided with a radio-frequency identification (RFID) tag. In another embodiment, the marking dispenser may be provided with a barcode. The type of information that may be encoded in the ID mechanism may include, but is not limited to, product-specific information, user-specific information, other predetermined information of interest, and any combination thereof. The ID information encoded in the ID mechanism may be collected and used for various purposes, such as, but not limited to, real-time product verification, tracking which user location received a batch of marking paint, tracking marking paint inventory, tracking marking paint problems, and tracking marking paint usage.
