Abstract: A method involves identifying a leak location in a cable television system using a detection system, calculating a distance between the leak location and a plurality of shapes or points contained in map data to identify the nearest shape or point, and providing a piece of information corresponding to the nearest shape or point. The piece of information may be a street address or a device.

Abstract: Provided are a system and method for modifying detected radio frequency (RF) leak information in a cable television system. In one example, the method includes identifying a leak location and a leak magnitude in the cable television system using a detection system. A predefined range value may be automatically identified based on the leak location, where the range value is used to define an approximate distance between the cable television system and the detection system. The leak magnitude may then be modified based on the range value.

Abstract: Provided is a Doppler based automated direction finding system that detects radio frequency (RF) leaks in a cable television plant. During a ride-out, the system detects leaks and stores leak data, such as amplitude, location, and bearing. The stored data is uploaded to a computer that performs a leak analysis. The leak analysis isolates the leaks using Doppler-based bearing information and separates cable leaks from other RF sources, such as power sources and noise. Erroneous information that results from RF reflections (multi path) may be eliminated while processing the data using triangulation. After the leak analysis, the computer generates work orders and maps, makes the data available to users, and may also compile information and file reports based on the data.

Abstract: A cable leakage detection system to be placed in a moving vehicle for monitoring signal leakages in a cable television plant whereby an RF detection meter is combined with a global positioning system and a computer control unit to measure radio frequency signal strength, while maintaining the corrected distance between the vehicle and the source of the leak, determine longitude and latitude of the measured signal strength, and store the signal strength, longitude and latitude in data files.
