Article
Full-text available
In many application domains, wire faults can have dramatic consequences. Live wire diagnosis is often required to ensure permanent monitoring of the health of embedded cables. A novel reflectometry-based method for online wire diagnosis is presented. Chaos Time Domain reflectometry (CTDR) takes benefit of the properties of chaotic signals and shows...

This paper presents the first embedded health monitoring system able to analyze network/harness health using OMTDR (Orthogonal Multi-tone Time Domain Reflectometry) technology. OMTDR is a suitable candidate for on-line diagnosis as it permits interference avoidance by bandwidth control. Thanks to OMTDR's communication capability, network analysis a...
Article
Full-text available
From reflectometry methods, this work aims at locating accurately electrical faults in complex wiring networks. Increasing demand for online diagnosis has imposed serious challenges on interference mitigation. In particular, diagnosis has to be carried out while the target system is operating. The interference becomes more even critical in the case...

This paper presents an EMC (Electromagnetic Compatibility) compliant sensor able to detect and locate intermittent faults longer than 300 µs in wires in real time. The proposed System On Chip can diagnose any wire using different reflectometry-based methods. The injected signal's spectrum is designed to ensure a continuous harmless diagnosis. The A...

This paper presents EMC measurement results for an online wire-diagnosis system integrated in a vehicle. The spectrum control properties of the reflectometry-based MCTDR method make it a good candidate for EMC compliance. An Electronic Control Unit was modified to add MCTDR-based wire diagnosis function. Conducted and radiated EMC measurements wer...
Conference Paper

The cumulated lengths of electrical cables always increase in aircrafts: now up to 20 kilometers in a helicopter, 40 km in a fighter and 500 kilometers in a modern civil transport aircraft such as A380. Electrical wiring is a critical part in the nominal operation of a system. The importance of the wired network has thus grown to the same level as...

In this paper, we present a new application of electromagnetic topology to model the channel formed by an aircraft harness to develop fault detection and localization. This method allows the numerical simulation of reflectometry signals for any kind of wired uniform and non-uniform.
Article
Full-text available
A new post-processing approach which aims at reducing the dispersion effect of the wave travelling inside a waveguide is presented. The main objective is to improve the time domain reflectometry measurements performed over long-distance cables, relative to the wavelength λ. A real-case scenario is presented so that the gain of this method can be ap...

Nowadays, increasing demands for on-line wire diagnosis using reflectometry have imposed serious challenges on signals processing, bandwidth control and interference mitigation. On-line diagnosis aims at detecting and locating faults accurately while the target system is running. In this work, a new reflectometry method, named “Orthogonal Multi-Tone...
Conference Paper
Full-text available
Currently, on-line wire diagnosis using reflectometry is under intensive investigation, aiming at detecting and locating faults on wiring networks while the target system is operating. The idea is to inject a broadband test signal in the network under test and analyse the signal reflected by each impedance discontinuity. However, the presence of na...

La réflectométrie consiste à émettre un signal sur un câble point-à-point ou un réseau de câbles puis à mesurer les échos renvoyés. Le retard et l'amplitude de ces échos permettent d'obtenir des informations sur la structure ou sur les défauts électriques présents dans ce réseau. Plus généralement, chaque écho correspond à une singularité. On peut...

Since silicon-nanocrystals were discovered, their particular properties are under study. Thanks to quantum confinement, silicon nanostructures can exhibit high conversion efficiency compared with Si-bulk. Recent studies have shown the possibility of using silicon nano-crystals in MOS (metal-oxide-semiconductor) or MIS (metal-insulator-semiconductor...

Since the discovery of the visible luminescence of porous silicon [1], there is a great interest to fabricate optoelectronic silicon devices. Thanks to the quantum confinement, silicon nanostructures can exhibit high conversion efficiency compared with bulk Si [2, 3]. Some techniques have been developed to obtain silicon nanostructures as silicon n...
