Latest Patents

Joo-Won Kim holds a patent for a "Time-frequency domain reflectometry apparatus and method." This invention provides a high-resolution reflectometry solution that operates simultaneously in both the time and frequency domains. The apparatus utilizes time-frequency signal analysis and a chirp signal multiplied by a Gaussian time envelope. The Gaussian envelope ensures time localization, while the chirp excites the system under test with a swept sinewave covering a frequency band of interest. The high-resolution detection of the reflected signal is achieved through a time-frequency cross-correlation function. This technology allows for accurate localization of faults in wires and cables by measuring the time delay offset obtained from the frequency offset of the reflected signal. Additionally, the apparatus enables automated diagnostic procedures of wires and cables under test by controlling peripheral devices.
