1 Furse, Cynthia M.Analysis of spread spectrum time domain reflectometry for wire fault locationSpread spectrum time domain reflectometry (SSTDR) and sequence time domain reflectometry have been demonstrated to be effective technologies for locating intermittent faults on aircraft wires carrying typical signals in flight. This paper examines the parameters that control the accuracy, latency, ...Spread spectrum; Sequence time domain reflectometry; STDR; SSTDR; Wire fault location; Aging wire detection; Arc detection2005-12
2 Furse, Cynthia M.Feasibility of reflectometry for nondestructive evaluation of prestressed concrete anchorsConcrete dams and other large civil structures utilize steel cable anchors to improve strength and stability. Reflectometry methods that have been used for location of faults in electrical systems are examined as a possible method for location and quantization of possible deterioration on concrete ...Concrete anchors; Steel cable anchors; Reflectometry; Nondestructive evaluation; Spectral time-domain reflectometry2009-11
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.Invisible fray: a critical analysis of the use of reflectometry for fray locationSignificant international research and development efforts have been devoted to methods and equipment for locating wiring faults, particularly those on aging aircraft. Several reflectometry methods that send high frequency signals down the line and analyze the returned reflections have risen to the...Reflectometry; Fray location; Invisible fray; Fault location; Aging wiring; Spread spectrum reflectometry2006-06
5 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...CMOS sensor; Pseudo-random noise; Reflectometry Methods; Spread spectrum; Wire fault location; Time Domain Vernier (TDV) method2007-01
6 Harrison, Reid R.; Tabib-Azar, MassoodMicrocontroller-based wireless recording unit for neurodynamic studies in saltwaterThis paper presents the design of a biocompatible implantable neural-recording unit for Aplysia californica, which is a common sea slug. Low-voltage extracellular neural signals (< 250 μV) are recorded using a high-performance low-power low-noise preamplifier that is packaged with programmable dig...Sea slug; Data acquisition; Implantable; Low-noise amplifier; Low-power circuits; Neural sensor; Telemetry2006-10
7 Furse, Cynthia M.Mixed-signal reflectometer for location of faults on aging wiringLocation of faults on aging cables is of great interest to maintainers of aircraft, cars, power distribution systems, communication systems, etc. One class of methods for locating faults is frequency domain reflectometry (FDR), using sine waves as the forcing function. A new frequency domain method...Mixed signal reflectometer; Fault location; Aging wiring; Nondestructive evaluation; Reflectometry2005-12
8 Furse, Cynthia M.Multicarrier reflectometryA new reflectometry method called multicarrier reflectometry (MCR) for fault location in cables is proposed. MCR combines a weighted set of sinusoidal excitations into a signal that is sent down the wire. The reflected signal from the cable under test is analyzed in order to determine the length of ...Multicarrier reflectometry; MCR; Fault location2006-06
9 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
