![]() | Furse, Cynthia M. | Capacitance and inductance sensor circuits for detecting the lengths of open- and short-circuited wires | The length of an open- or short-circuited wire is linearly proportional to the capacitance or inductance of the wire, respectively. Several types of simple and inexpensive circuits are introduced to measure these values. Open-circuited (capacitance) measurements are very effective. Short-circuited ... | Aging aircraft wire; Capacitance sensors; Fault detection; Inductance sensors | 2009-08 |

![]() | 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 |
