Abstract: A marking system may hold a container from which markers are dispensed to mark the presence or absence of an underground facility in a dig area. The container may identify a marker characteristic regarding the markers in the container. The marking system may receive activation of a trigger, dispense a marker from the container when the trigger is activated, and store the marker characteristic and time data when the trigger is activated. In other embodiments, the marking system may dispense a marker, determine location data and/or time data, and substantially simultaneously trigger the dispensing of the marker and logging of the location data and/or the time data. The location data identifies a geographic location where the marker is dispensed and the time data identifies the time when the marker is dispensed.

Abstract: Methods and apparatus for detecting a presence or absence of an underground facility and generating electronic records of locate operations are described herein. An exemplary apparatus includes an actuator and at least one receiver antenna to detect a magnetic field from the underground facility. The apparatus further includes a processor coupled to a memory, which may at least be further coupled to the at least one receiver antenna. Upon execution of processor-executable instructions stored in the memory, the processor logs in the memory locate information relating at least in part to operation of the at least one receiver antenna. The processor logs the locate information in response to actuation of the actuator and/or at least one event based at least partially on a characteristic of the magnetic field detected by the at least one receiver antenna.

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.

Abstract: Methods and apparatus for generating electronic records of marking operations for underground facilities/utilities. Electronic records of marking information may be logged/stored in local memory of a marking device, formatted in various manners, processed and/or analyzed at the marking device itself, and/or transmitted in whole or in part to another device (e.g., a remote computer/server) for storage, processing and/or analysis. In one example, service-related information and/or ticket information is collected and logged into an electronic record of a marking operation. Such information may in some cases be logged together with actuation data based on one or more actuations of a marking device (e.g., a trigger-pull to dispense marking material).

Abstract: Marking devices for dispensing a marking substance on the ground and marking methods are provided. The marking devices and marking methods use one or more detection mechanisms to detect one or more characteristics of the marking substance. In some embodiments, the detection mechanism may be, but is not limited to, an optical sensor, an olfactory sensor, a weight sensor, a switch device, and any combination thereof. The one or more detection mechanisms may provide, for example, the capability to: (1) determine the type of marking substance that is installed in the marking device; (2) determine in advance of or during a marking operation the amount of marking substance within the marking dispenser; and (3) determine when the marking dispenser is becoming empty.

Abstract: Methods and apparatus for generating a searchable electronic record of a locate operation in which a locate technician, using one or more physical locate marks, identifies a presence or an absence of at least one underground facility within a dig area. A digital image of a geographic area comprising the dig area is electronically received, and at least a portion of the received digital image is displayed on a display device. Location information regarding an identified location of the at least one physical locate mark is also electronically received and, based at least in part on the received location information, one or more digital representations of the identified location of the physical locate mark(s) is/are included in the displayed digital image so as to generate a marked-up digital image. Information relating to the marked-up digital image is electronically stored and/or electronically transmitted so as to generate the searchable electronic record of the locate operation.

Abstract: Methods and apparatus for facilitating detection of a presence or an absence of at least one underground facility within a dig area. Source data representing one or more input images of a geographic area including the dig area is electronically received at a first user location, which may be remote from the dig area. The source data is processed so as to display at least a portion of the input image(s) on a display device. One or more indicators are added to the displayed input image(s), via a user input device associated with the display device, to provide at least one indication of the dig area and thereby generate a marked-up digital image. In the case of a staged excavation project, the input image, or a plurality of associated images, may include indicia of multiple dig areas corresponding to multiple stages of the staged excavation project.

Abstract: Methods and apparatus for facilitating detection of a presence or an absence of at least one underground facility within a dig area. Data representing an aerial image of a geographic area including the dig area is electronically received, the data including geo-coding or geographical identification metadata associated with the aerial image. At least a portion of the aerial image is displayed on a display device, including at least one map symbol, street name, region, and/or landmark description superimposed upon or displayed separately from the geographic area.
