摘要： Cable communication systems and methods to provide voice and/or data services to subscriber premises via a cable plant that conveys upstream information over an upstream path bandwidth, and a cable modem system including one or more demodulation tuners to receive and demodulate one or more upstream radio frequency (RF) signals. An RF signal includes an encoded carrier wave having a carrier frequency of between approximately 5 MHz and 25 MHz that is modulated using quadrature amplitude modulation (QAM) with voice and/or data information constituting at least some of the upstream information. A modulation order of the QAM for the first upstream RF signal is at least 32 and as high as at least 256, and at least one demodulation tuner of the cable modem system is configured to receive and demodulate the first upstream RF signal.

摘要： An HFC cable communication system comprising: a CMTS having a first attenuator to attenuate one or more upstream signals applied to the CMTS; an optical link having a dynamic range and comprising an optical receiver having a second attenuator to attenuate the upstream signal(s) and an optical transmitter having a third attenuator to attenuate the upstream signal(s); a coaxial RF link comprising one or more RF amplifiers having a fourth attenuator to attenuate the upstream signal(s); and one or more subscriber modems to generate the upstream signal(s) at respective transmit RF signal levels. The CMTS implements a long loop ALC to set the transmit RF signal level(s) based on received RF signal levels of the upstream signal(s) at the CMTS. Respective values for the first, second, third and fourth attenuators are selected based on the dynamic range of the optical link so as to facilitate implementation of the long loop ALC and effective transmission of upstream information carried by the upstream signal(s).

摘要： 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. In yet another aspect, a requesting party may provide an acknowledgement of receipt (e.g., a “return receipt”) for one or more received notifications.

摘要： Locate and/or marking operations involve detecting and/or marking a presence or an absence of at least one underground facility within a dig area, wherein at least a portion of the dig area is planned to be excavated or disturbed during excavation activities. One or more attributes of a locate and/or marking operation requested in a locate request ticket are assessed to provide one or more ticket assessment outcomes. Ticket information is obtained from the locate request ticket, and historical information (e.g., historical damage reports, historical records of previously completed locate request tickets) is selected and analyzed based on the ticket information so as to assign at least one risk designation to the ticket. The risk designation(s) is/are transmitted and/or stored so as to facilitate clearing the locate request ticket and/or dispatching a locate technician to perform the locate and/or marking operation.

摘要： Methods and apparatus for cutting a trench (e.g., for a fiber optic cable or wire conductors) in an existing covering surface (e.g., a road surface), wherein the trench has a depth of approximately 10 to 12 inches and a width of approximately 0.5 to 1.25 inches. Debris from the cut trench is evacuated (e.g., vacuumed) from the trench as the trench is cut. The trench may be backfilled by flowing a non-shrinking composition into at least a portion of the trench and, after hardening of the non-shrinking composition, applying a topping material to a remaining portion of the trench. In one example, the non-shrinking composition is configured to rigidify within one hour of being flowed into the trench, be substantially impermeable thereafter (e.g., having a hydraulic permeability of less than 0.0000001 cm/s upon drying), and be non-compressible and non-expanding.

摘要： 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.

摘要： Marking material is dispensed onto a target surface using a marking device, and one or more images are captured by one or more camera systems attached to the marking device. The image(s) is/are analyzed to determine tracking information indicative of the a motion or an orientation of the marking device. The tracking information is analyzed to determine marking information relating to the dispensed marking material. In one example, the image(s) is/are analyzed to obtain an optical flow plot indicative of a path on the target surface traversed by the marking device. One or more reference plots respectively representing a plurality of reference marking patterns are compared to one or more portions of the optical flow plot to identify at least one reference marking pattern that substantially matches the portion(s) of the optical flow plot.

摘要： 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.
