Abstract: Methods for reducing ingress in a neighborhood node of a cable communication system. The node includes an RF hardline coaxial cable plant and multiple subscriber service drops to convey upstream information from multiple subscriber premises over an upstream path bandwidth. A test signal having a frequency falling within the upstream path bandwidth is transmitted proximate to one or more potential points of ingress into the hardline cable plant. Based on signal amplitudes at the test signal frequency representing test signal ingress into the hardline cable plant, one or more faults in the hardline cable plant are specifically identified and remediated so as to significantly reduce a noise power in the node in at least a portion of the upstream path bandwidth below approximately 20 MHz. In one example, hardline plant-related and/or subscriber-related faults are remediated so as to significantly reduce ingress arising from terrestrial short wave radio signals.

Abstract: A digital image (e.g., a facility map, an aerial/satellite image, an engineering drawing) is displayed on a display device of a locate receiver used to detect a presence or absence of an underground facility. Image data used to generate the image is selected based on information obtained from a ticket associated with a locate operation for which the locate receiver is used, and geographic information indicative of a location of the locate receiver. Based on a strength of a magnetic field received by an RF antenna of the locate receiver, one or more electronic markings representing a detected presence of the underground facility are overlaid on the displayed digital image.

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 vehicle-based complex event processing (CEP) engine executes on a hardware computer processor in a vehicle. The CEP engine receives a first input stream onto which vehicle information related to the vehicle is published, and applies at least one query to the first input stream. The CEP engine then assesses, based on application of the query/queries, if a vehicle-related event has occurred and, if so, the CEP engine publishes an indication of occurrence of the vehicle-related event on at least one output stream of the CEP engine. In one example, the CEP engine may receive a second input stream onto which image information is published, wherein the image information is based at least in part on data provided by at least one on-board vehicle camera.

Abstract: One or more markers are dispensed on ground, pavement or other surface in a dig area to be excavated or disturbed during excavation activities, so as to provide a visual indication of a presence or an absence of one or more underground utilities in the dig area. One or more signals are wirelessly transmitted in response to the dispensing of the one or more markers, wherein the signal(s) represent(s) first data relating to marking information that is provided by a tag reader and that is associated with the dispensed marker(s).

Abstract: Locating and/or marking equipment, such as a locate transmitter or locate receiver, a marking device, or a combined locate and marking device, may be communicatively coupled to and/or equipped with a mobile/portable device (e.g., a mobile phone, personal digital assistant or other portable computing device) that provides processing, electronic storage, electronic display, user interface, communication facilities and/or other functionality (e.g., GPS-enabled functionality) for the equipment. A mobile/portable device may be mechanically and/or electronically coupled to the equipment, and may be programmed so as to log and generate electronic records of various information germane to a locate and/or marking operation (e.g., locate information, marking information, and/or landmark information). Such records may be formatted in various manners, processed and/or analyzed on the mobile/portable device, and/or transmitted to another device (e.g., a remote computer/server) for storage, processing and/or analysis.

Abstract: Methods, apparatus, and systems for providing information regarding a locate and/or marking operation to identify a presence or an absence of at least one underground facility within a dig area. At least one notification indicating a status of the locate and/or marking operation is electronically transmitted and/or stored so as to inform at least one party associated with requesting the operation (a “requesting party,” e.g., an excavator, a property owner, a facility owner, a regulatory authority, a damage investigator, etc.) of the status of the operation. In one aspect, a requesting party may designate a preferred format, content, and/or method of receiving notifications regarding the locate and/or marking operation. In another aspect, a computer-generated GUI is provided to facilitate submission of requests, generation of “virtual white line” images to indicate one or more dig areas on a digital image of a work site, and/or selection of notifications and preferences for same.

Abstract: Marking methods for dispensing markers on the ground are provided. The 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: Cable communication systems and methods to provide voice and/or data services to subscriber premises in one or more neighborhood nodes via an ingress-mitigated cable plant that conveys upstream information over an upstream path bandwidth. One or more upstream radio frequency (RF) signals have a carrier frequency of between approximately 5 MHz and 19.6 MHz and are modulated using quadrature amplitude modulation (QAM) with voice and/or data information constituting at least some of the upstream information. An example RF signal defines a channel having an average channel power, and a highest value for an average noise power between 5 MHz and 19.6 MHz in the upstream path bandwidth of a given neighborhood node, as measured over at least a 24 hour period, is at least 25 decibels (dB) below the average channel power and/or less than 20 decibels (dB) above a noise floor associated with the neighborhood node.

Abstract: A grid is displayed on a display device to provide a reference for a geographic area including an excavation site. User input is acquired that relates to a geographic location of at least one physical locate mark applied by a technician to a ground surface at the excavation site to indicate a presence or an absence of at least one underground facility at the excavation site. Based on the user input, at least one digital representation of the at least one physical locate mark is added to the displayed grid so as to generate a marked-up image. Information relating to the marked-up image is electronically stored and/or electronically transmitted so as to generate an electronic manifest.
