    The Department of Defense (DoD) has specific goals to reduce acquisition cost, shorten development time and allow rapid technology insertion into avionics systems. The DoD funded Boeing to perform a study on methods to accomplish these goals. The Diagnostics for Acquisition (DFA) study was broken into three efforts: simulation, demonstration, and studies. In the simulation effort, creation of func... View full abstract»

    Most of the test programs used to verify the performance of digital electronics in today's factories and repair/overhaul facilities continue to use settled state (static) testing including many programs executing on high speed test systems. The term “at speed” typically means that the rate at which new test patterns are introduced to a circuit under test matches the rate at which the c... View full abstract»

    This paper addresses using information derived from Built-in-Test (BIT) to fault diagnose Units Under Test (UUTs), wherever possible. This philosophic approach to diagnostic testing is not new. It has been studied over and over again over the past 20 years under the visor of “Integrated Diagnostics”, but it has yet to be truly implemented in a “real life” military diagnosti...

    The Component Object Model (COM) is an object-oriented standard for reusable binary components. COM reusability is based not only on component reuse, but on interface reuse. Client programs access COM objects only through defined interfaces, which may be reused from object to object. Interfaces hide implementation details (encapsulation). Interface reuse and inheritance provide runtime polymorphis... View full abstract»

    Publication Year: 1999, Page(s):215 - 221
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (384 KB)

    Integrated Diagnostics is an iterative process that lives within Systems Engineering but to date there has not been a consistent approach for implementing metrics to monitor diagnostic system enhancements or performance. The DoD has often fielded systems or incorporated “diagnostic enhancements” to systems without having a standardized way for acquisition managers to evaluate or monito... View full abstract»

    In recent years robotics have been utilized in conjunction with diagnostic probing of circuit cards. Traditionally, manual probing is required to isolate component failures. This requires program interruption, use of reference documents and judgment by the operator. It is expected that the operator will locate the proper test point and place the probe with sufficient force to make contact. Often, ... View full abstract»

    Test Program Sets, TPS, designed to run on automatic test equipment, ATE, should produce identical results when moved. Sometimes this does not happen. To answer stability questions we have control charted the various ranges of the DMM, for three different IFTE Base Shops. The data range over approximately 260 days producing eight (8) points. Averages of three points and their repeatability's are p... View full abstract»

    In this paper, we present a Hidden Markov Model (HMM) based algorithm for online fault diagnosis in complex large-scale systems with partial and imperfect tests. The HMM-based algorithm handles test uncertainties and inaccuracies, finds the best estimate of system states and identifies the dynamic changes in system states, such as from a fault-free state to a faulty one. We also present two method... View full abstract»

    Capacitance-type alcohol gas sensors using porous silicon (PS) layer as sensitive film were fabricated to measure low alcohol gas concentration. Though sensors using PS layer have shown high sensitivity by large internal surface area, there is still much room for improvement to measure low breath alcohol concentration especially at room temperature. In this work, we measured the variation of the c... View full abstract»
