Abstract: A bare grid is displayed on a display device. At least one digital representation of at least one physical locate mark is added to the displayed grid to generate a marked-up grid. The physical locate mark(s) include(s) non-white paint and/or a non-white flag, and is/are applied during a locate operation performed after generation of and pursuant to a locate request ticket relating to a dig area that is planned to be excavated or disturbed during prospective excavation activities. The locate operation comprises providing at least one visible warning to an excavator performing the prospective excavation activities, using the physical locate mark(s), of a presence or an affirmative absence of at least one underground facility at the dig area specified in the locate request ticket. Information relating to the marked-up grid is electronically stored and/or transmitted so as to generate a searchable electronic record of the locate operation.

Abstract: Methods and apparatus for generating a searchable electronic record of a locate operation in which a presence or an absence of at least one underground facility within a dig area may be identified using one or more physical locate marks. Source data representing one or more input images of a geographic area comprising the dig area is received and processed so as to display at least a portion of the input image(s) on a display device. One or more digital representations of the physical locate mark(s) applied to the dig area during the locate operation are added to the displayed input image(s) as “locate mark indicators” 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 generate the searchable electronic record of the locate operation.

Abstract: Systems and methods for generating electronic records of locate operations and marking operations are described. Exemplary systems and methods include marking devices that generate, store and/or transmit electronic records of marking information, locate devices that generate, store and/or transmit electronic records of locate information, and locate devices and marking devices that communicate with each other (and optionally with other devices or systems) to share/exchange locate information and/or marking information. An exemplary method for analyzing and processing locate information and marking information includes a computer-implemented method for visually rendering (e.g., in a display field of a display device) various aspects of locate and marking operations.

Abstract: 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. One or more RF signals include an encoded carrier wave having a carrier frequency of between 5 MHz and 16.4 MHz that is modulated using a Time Division Multiple Access (TDMA) protocol or an Advanced Time Division Multiple Access (ATDMA) protocol and quadrature amplitude modulation (QAM) with voice and/or data information constituting at least some of the upstream information. An aggregate deployed upstream capacity of the one or more RF signals to convey the upstream information in a portion of the upstream path bandwidth between 5 MHz and 16.4 MHz is at least approximately 12 Megabits per second (Mbits/s).

Abstract: 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 5 MHz and 19.6 MHz that is modulated using a Time Division Multiple Access (TDMA) protocol or an Advanced Time Division Multiple Access (ATDMA) protocol and 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 at least one demodulation tuner of the cable modem system is configured to receive and demodulate the first upstream RF signal.

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 a location at which the marker(s) is/are dispensed, and/or one or more characteristics of the dispensed marker(s).

Abstract: 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 at least approximately 42 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 256, and at least one demodulation tuner of the cable modem system is configured to receive and demodulate the first upstream RF signal.

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.
