Title: Innovations by Jingnan Zhao in Road Surface Monitoring
Introduction
Jingnan Zhao is an accomplished inventor based in Edison, NJ, with a focus on advanced technologies for road surface monitoring. He holds two patents that showcase his innovative contributions to the field of distributed fiber optic sensing systems.
Latest Patents
One of his latest patents is titled "Road surface conditions detection by distributed optic fiber system." This invention utilizes a fiber optic sensing cable positioned along the side of a paved road, which runs parallel to the driving direction. The system employs distributed fiber optic sensing (DFOS) using Rayleigh backscattering to monitor the cable under dynamic vehicle loads. The unique interaction of vehicles with distressed pavement generates distinct localized signals, which can be differentiated from those produced by vehicles on smooth surfaces. Machine learning techniques are applied to assess overall road surface quality and localize pavement damage. Various methods, including power spectral density estimation, principal component analysis, support vector machine (SVM) combined with principal component analysis (PCA), local binary pattern (LBP), and convolutional neural network (CNN), are utilized to develop the machine learning models.
Another significant patent by Zhao is "Multiple lane real-time traffic monitor and vehicle analysis using distributed fiber sensing." This invention advances the capabilities of distributed fiber optic sensing systems (DFOS) by enabling real-time monitoring and identification of traffic patterns across multiple lanes of a highway. The system employs a multiple-transverse fiber optic cable arrangement positioned beneath the roadway to detect and analyze traffic effectively.
