Abstract: A microprocessor executable method and system for determining the semantic relatedness and meaning between at least two natural language sources is described in a prescribed context. Portions of natural languages are vectorized and mathematically processed to express relatedness as a calculated metric. The metric is associable to the natural language sources to graphically present the level of relatedness between at least two natural language sources. The metric may be re-determined with algorithms designed to compare the natural language sources with a knowledge data bank so the calculated metric can be ascertained with a higher level of certainty.

Abstract: An apparatus for collecting characteristics of a power line in a broadband over power line system that comprises a power line characteristic measuring device for measuring power line characteristics and a collector unit for collecting data from the power line characteristic measuring device and sending the data over the broadband over power line system to a remote location where the collector unit is a regenerator. Further, the apparatus can comprise a coupler, to couple the power line to the power line characteristic measuring device and the collector unit and allows a broadband over power line signal to pass from the power line to the collector unit.

Abstract: Disclosed embodiments provide methods and systems for the configuration of broadband over power lines. The configuration entails calculating a desired distance between nodes by measuring a noise floor on a power line, measuring a signal power level on the power line and determining the desired distance based on a target signal-to-noise ratio.

Abstract: A filter system for a broadband over power line system comprises a power line and a first line node and second line node of the broadband over power line system using the power line. The filter system also comprises a filter on the power line placed between the first and second line node, to attenuate a range of frequencies. Wherein the range of frequencies can be the entire range of mode frequencies used in the broadband over power lines system.
