METHODS AND APPARATUS TO ESTIMATE CABLE LENGTH - A simplified explanation of the abstract

This abstract first appeared for US patent application 18072458 titled 'METHODS AND APPARATUS TO ESTIMATE CABLE LENGTH

Simplified Explanation

The abstract describes a patent application for a device that can estimate the length of a cable used for communication. The device includes various circuitry components to establish cable communication, sample cable voltages, determine echo coefficients, and estimate the cable length.

  • The device includes processor circuitry to establish cable communication.
  • It also includes analog to digital converter circuitry to sample cable voltages over time.
  • Echo estimator circuitry is included to determine echo coefficients corresponding to the sampled voltages.
  • Physical length estimator circuitry is included to identify specific echo coefficients and estimate the cable length based on these coefficients.

Potential Applications

  • This technology can be used in various industries that rely on cable communication, such as telecommunications, networking, and audio/video systems.
  • It can be applied in the installation and maintenance of cable systems to accurately determine the length of cables required.

Problems Solved

  • Accurately estimating the length of a cable can be challenging, especially in situations where the cable is already installed or when there are multiple echoes.
  • This technology solves the problem of estimating cable length by utilizing echo coefficients and specific thresholds to identify near end and far end echoes.

Benefits

  • The device provides a simplified and efficient method for estimating cable length.
  • It eliminates the need for manual measurements or complex calculations.
  • Accurate cable length estimation can lead to cost savings in cable installations and maintenance.


Original Abstract Submitted

An example first device includes: processor circuitry configured to establish a cable communication; analog to digital converter circuitry configured to sample cable voltages over time; echo estimator circuitry configured to determine a plurality of echo coefficients corresponding to the plurality of voltages; and physical length estimator circuitry configured to: identify a first echo coefficient in the echo coefficients that satisfies a static threshold, the first echo coefficient corresponding to a near end echo; identify a second echo coefficient in the echo coefficients that satisfies a dynamic threshold, the second echo coefficient corresponding to a far end echo; and estimate the length of a cable for the cable communication based on the first echo coefficient and the second echo coefficient.
