Title: Innovations by Philip F. Chang

Introduction

Philip F. Chang is an accomplished inventor based in Langhorne, PA (US). He holds 2 patents that showcase his expertise in communication technologies. His work has significantly contributed to advancements in error detection and signal measurement within wired communications networks.

Latest Patents

One of his latest patents is focused on the identification of a fault. This invention provides an apparatus, method, and system for determining the location of an error source. The system retrieves equalization coefficients and calculates an average period of time between localized peak amplitudes. This average period is then multiplied by a velocity of propagation associated with a communication channel to approximate the error source's location. The equalization coefficients correspond to the inverse of the frequency response associated with the communication channel and can be updated over time using various techniques.

Another notable patent by Chang involves the remote detection and measurement of data signal leakage. This invention discloses systems and methods for detecting and locating the ingress of an over-the-air signal into a wired communications network. Computing devices in various areas are configured to identify the amplitude of signals transmitted over the wired network as it varies by signal frequency. The system can determine the expected amplitude of the over-the-air signal and compare it with the amplitudes received over the wired communication path to identify the location of the signal's entry.
