20100026310 | Communication System Fault Location Using Signal Ingress Detection - Detecting ingress of a transmitted signal into a cable communication system due to a radio frequency signal transmitted from a moving vehicle and interrogation of transmitter location over a separate wireless link provides monitoring of shielding integrity or flaws there in a cable communication system. The location of a shielding flaw may then be precisely located in a closed loop fashion without risking overload of the cable communication system or interference with upstream signaling therein by detecting ingress signal strength and controlling transmitted signal strength while providing a user-perceptible indication of ingress signal strength which is compensated for the control of transmitted signal strength and thus indicates proximity of a hand-held instrument or transmitter to said shielding flaw. | 02-04-2010 |
20110055632 | Wireless Diagnostic System - Results of field testing of portions of a distributed system such as a Broadband Communications System from a testing device to a controller which downloads programmed test protocols and sequences thereof to the separate testing device over a wired or wireless link and thereafter can be used to control the testing device as well as display test results and provide analysis of the test results and suggest procedures to technical personnel. The controller then can transmit the test data to a central facility or distribution hub in substantially real-time together with work performance data where full technical analysis can be performed. The test data and results of analysis can then be distributed as desired such as to a management analysis facility to support improvement of efficiency of the system and the operation thereof. | 03-03-2011 |
20110085456 | Signal Egress Alarm - Notification of a detected potential egress signal from a Broadband Communications System (BCS) is expedited by detection of signal Strength at a mobile detector which is above a user-specified threshold. When a potential egress signal having a strength above a user-specified threshold is detected, it is reported with other, lesser strength egress signals, immediately over a wireless link to a central server which is dedicated to a given BCS or which provides a notification service to a plurality of such systems. The central server may provide additional processing such as for authenticating a detected signal as an egress signal and/or estimating egress signal strength at a shielding flaw and, responsive to a detected signal having a signal strength above the user-specified threshold, sending notifications of the signal egress detection or shielding flaw a user-specified number of times at user-specified intervals while the signal egress persists or until earlier terminated. | 04-14-2011 |
20120042213 | WIRELESS DIAGNOSTIC SYSTEM - Results of field testing of portions of a distributed system such as a Broadband Communications System are communicated from a testing device to a device including a display which downloads test protocols to the testing device. The testing device can thereafter operate in a stand-alone manner and transfer the results of testing and analysis to a device including a display that may comprise virtually any wireless communication device by storing an application or information therein. The communication device can transfer captured test data and analysis to a central facility for storage, further analysis and/or management purposes. | 02-16-2012 |
20120257661 | SHIELDING FLAW DETECTION AND MEASUREMENT IN QUADRATURE AMPLITUDE MODULATED CABLE TELECOMMUNICATIONS ENVIRONMENT - Signal egress from a shielding flaw in a cable telecommunication system is detected, even where signals carried by the cable telecommunication system are quadrature amplitude modulated signals that statistically resemble broadband noise by generating a marker signal comprising a double side band, suppressed carrier signal in the fringes of contiguous frequency bands and at a power level which cannot cause perceptible interference with signals in those contiguous frequency bands. The separation of the sidebands comprising the marker signal can unambiguously identify the marker signal and can distinguish between different cable telecommunication systems installed in the same geographic area. The marker signal can be additionally coded by varying the frequency and/or amplitude of the modulating signal used to create the marker signal. | 10-11-2012 |

20140195176 | DERIVING BROADBAND COMMUNICATION SYSTEM SERVICE AREA FOR SIGNAL LEAKAGE DETECTION - An improved, adaptive and uniformly applicable estimation of the percentage or fraction of a broadband communication system (BCS) plant that is monitored for signal egress during a given period of time is provided by generating and collecting polygons along all possible routes traversed by DOS service vehicles within a service area, preferably by comparison with a roadway map, to define the service area with improved accuracy. The number of polygons generated and collected is then limited by the number of polygons in which DCS service vehicles have been reported in a given period of time or inspection interval. The limited number of polygons is then divided by the number of polygons generated and collected to determine a fraction or percentage of the BCS system which has been monitored during the given time period and can be used in a computation of a cumulative leakage index (CLI) value. | 07-10-2014 |
