Faults in aircraft wiring have been implicated in a number of severe aircraft incidents including the TWA800 and SwissAir111 crashes. Electrical wiring is the number one cause of home and building fires\, and is responsible for numerous incidents in consume r product safety\, photovoltaic systems\, vehicular safety/reliability\, s afety of nuclear facilities\, reliability of power distribution systems an d communication systems\, and others.\n\nWhat could possibly be so hard ab out finding these electrical faults? This lecture describes the real-world challenges in electrical systems – live signals\, switching systems\, g rounding and moisture\, vibration\, and more. We’ll talk about how elect romagnetics\, signal processing\, artificial intelligence\, chip and hardw are design all merge to create new sensors that can detect and locate faul ts in critical systems. In particular\, I’ll describe the development an d use of spread spectrum time domain reflectometry (SSTDR) for finding fau lts on live electrical systems. Using a tiny pseudo-noise (PN) code simila r to your cell phone or GPS signal\, SSTDR hides within the noise margin o f existing signals\, enabling continuous monitoring and location of very h ard-to-find intermittent faults. And along with SSTDR came a very broad fa mily of broadband reflectometry systems and algorithms for analysis of the reflection signatures\, which we’ll discuss.\n\nAlong with the technica l journey\, I’ll also describe my entrepreneurship journey as we took th is exciting research off the bench and into the real world. Today SSTDR is used in aircraft manufacturing\, handheld electrical testing\, undersea c able testing\, and has recently been approved for installation on Network Rail systems (UK). But our work is not done. Electrical systems are comple x and varied\, and some very gnarly problems remain. I’ll share a vision for the future\, and some ideas about what it will take to get there.\n\n Co-sponsored by: Frank Feather\, Chair\, PE 31 - Power and Energy Society chapter\, NJ coast section\n\nSpeaker(s): Cynthia Furse\, \n\nAgenda: \nLo g in to Webex: 5.45pm\, Checks and introducing speaker: 5.50 - 6.00pm\n\n6 .00 to 6.45pm Talk "Arch and Sparkss - finding fault on live wires"\n\n6.4 5pm - 7.00pm Question and Answers.
