The objective of this proposal is to create and deploy a complete in situ wire fault location system for aging aircraft utilizing low power spread spectrum sensing methods. These methods have been demonstrated for accurate fault location on wires carrying power or digital data signals. This method… More

Aging aircraft wiring has been identified as an area of critical national concern, due to safety problems, maintenance expense, and lost mission capable time. The objective of this proposal is to create and deploy a wire fault location system for aging aircraft utilizing spread spectrum sensing… More

LiveWire Test Labs, Inc., in cooperation with the Center of Excellence for Smart Sensors at the University of Utah is working towards the full development of "smart connectors" and smart circuit breakers that can locate faults on live wires in flight. These faults are typically too small to locate… More

The objective of this proposal is to develop and integrate an Embedded Smart Connector (SC) with wire diagnostic technology that can be temporarily or permanently installed into the aircraft wiring system to report the health of the vehicle wiring. This smart connector can be used to detect and… More

The objective of this proposal is to develop a feasible design for intermittent electrical fault detection and location for a weapons system using analog S/SSTDR for continual monitoring. We have already demonstrated the feasibility of the basic S/SSTDR technology for live aircraft in flight where… More

ABSTRACT: Weapon systems or other high value electrical systems within the US military are all subject to wiring faults and degradation. Additionally, weapon systems are kept in service longer because of shrinking defense budgets, further compounding the risks associated with wiring systems. The… More

The use of Spread Spectrum Time Domain Reflectometry (SSTDR) that has already been proven in aerospace applications will be adapted and optimized for detection and location of wiring faults in shipboard systems. SSTDR is the only technology that allows MCS fault detection and isolation, on fully… More
