Furse, Cynthia M. | Application of phase detection frequency domain reflectometry for locating faults in an F-18 flight control harness | The 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 harness | 2005-05 |

Furse, Cynthia M. | Down to the wire | As 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 systems | 2001-01-01 |

Furse, Cynthia M. | Feasibility of spread spectrum sensors for location of arcs on live wires | Spread 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 wires | 2005-12 |

Furse, Cynthia M.; Harrison, Reid R. | Low-power STDR CMOS sensor for locating faults in aging aircraft wiring | A 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 location | 2006-01-01 |

Furse, Cynthia M. | Noncontact probes for wire fault location with reflectometry | This 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 wire | 2006 |
