AbstractMSI is a leader in live diagnostic monitoring of conduits of aircraft electrical cables and harnesses. In a Phase II SBIR MSI has developed and is ready to flight test a new avionic instrument called the Digital Data Download Flight Information System. The first unit is for the F/A-18 to provide in-flight signature and flight data recording. The D3 is an open architecture that can be retrofitted into any aircraft. In an ongoing SBIR MSI has shrunk the D3 processing into a tiny instrumentation circuit called the Embeddable Programmable Instrumentation Chipset. MSI has built and demonstrated a Baseline Electrical System Troubleshooting System (BEST) using the same technology. The D3, BEST and EPIC perform continuous in-wiring signal monitoring and data logging. The D3 and EPIC are for on-board installations whereas the BEST is designed for live flight line weapon system inspection and troubleshooting. All units provide advanced diagnostics and root cause resolution. We propose new product set that adds real time parallelized NPD for blazing fast intermittent fault detection and simultaneous time stamped data recording of signals on multiple wires. These enhanced D3, BEST and EPIC will provide technicians with a systematic and comprehensive means for resolving intermittent faults. BENEFITS: The products that result from this research will have numerous practical applications in broad markets, especially for real time troubleshooting of complex electronic systems. It will provide a new tool to continuously inspect to detect intermittents and identify the root cause of unexplained, reoccurring failures. We see a massive commercial market for the same purpose in complex commercial electronic systems. Commercial equipment owners and facilities can use the same systems with tailoring and modifications. Use can also be achieved without significant changes.
