1 Furse, Cynthia M.Application of phase detection frequency domain reflectometry for locating faults in an F-18 flight control harnessThe performance of a phase-detection frequency-domain reflectometer (PD-FDR) for locating open and short circuits (hard faults) in a Navy F-18 flight control harness has been tested, and the analytical expressions for accuracy verified. Nine different types of aircraft wires appear in this harness:...Phase detection; Frequency domain reflectometry; PD-FDR; Wire fault location; Aging wire; Flight control harness2005-05
2 Furse, Cynthia M.Down to the wireAs today's military and commercial aircraft age past their teen years, the many kilometers of wiring buried deep within their structures begin to crack and fray. Once thought to be rare and benign, such faults are found by the hundreds in a typical aircraft. Unlike obvious cracks in a wing or an e...Aging wiring; Wire fault location; Aging wire detection; Smart wire systems2001-01-01
3 Furse, Cynthia M.Feasibility of spread spectrum sensors for location of arcs on live wiresSpread spectrum methods are an important emerging class of sensors that have the potential to locate small, intermittent faults on energized aircraft power circuit wires. Previous work has demonstrated the use of these methods for hard faults (open and short circuits). This paper extends that work ...Spread spectrum sensors; Wire fault location; Live wires2005-12
4 Furse, Cynthia M.; Harrison, Reid R.Low-power STDR CMOS sensor for locating faults in aging aircraft wiringA CMOS sensor used to locate intermittent faults on live aircraft wires is presented. A novel architecture was developed to implement the Sequence Time Domain Reflectometry method on a 0.5- m integrated circuit. The sensor locates short or open circuits on active wires with an accuracy of +/-1 ft w...Aging aircraft wire; CMOS sensors; Fault detection; Pseudo-random noise; Reflectometry methods; Spread spectrum; Wire fault location2006-01-01

6 Furse, Cynthia M.Noncontact probes for wire fault location with reflectometryThis paper describes an approach to locate wire faults using reflectometry without physical contact with the wire conductor. This noncontact method is capable of locating faults on both dead and live powered wires with today's reflectometry technologies, and it does not require any modification or ...Wire fault location; Noncontact probes; Reflectometry; Capacitive coupling; Inductive coupling; Aging aircraft wire2006
