    The author identifies societal needs that the engineer can help fulfil, and things that the engineer must do to accomplish this. He examines anti-engineering biases experienced by Galileo, the Challenger engineers, in the health effects of EMF fields, and in the economics of engineering-based activities. He proposes a number of corrective actions.<> View full abstract»

    The built-in test and embedded diagnostics for two subsystems of the M1A2 main battle tank, the commander's independent thermal viewer and the hull/turret electronics unit, are examined. Each of these systems supports the requirements for elimination of special test equipment at the tank level and the use of standard army test equipment for test and repair at higher echelons of maintenance. The tradeoffs made during system requirements analysis and flow-down, which led to two unique design implementations, are described. The advantages and disadvantages of each approach are discussed.<> View full abstract»

    An overview is given of the Productivity, Reliability, Availability, and Maintainability (PRAM) Project 00-256, which aims to integrate the Digital Multimedia Information System (DMIS) into the Reconnaissance Module Automatic Test System (RMATS). Benefits to be derived from the incorporation of the DMIS and return on investment for the US Air Force are discussed. The process used to obtain approval and funding support for this advanced maintenance aiding and data collection system is described.<> View full abstract»

    A technique for quickly searching frequencies in a signal path to find and measure low-level spurs is described. It couples a wideband tuned receiver with a tuned digital, parallel filter bank analyzer to greatly reduce spur testing times. The receiver is step-tuned across the region of frequencies to be searched, and at each step the filter bank is step-tuned across the IF output. An example system is described, and search time and sensitivity are discussed.<> View full abstract»

    Testing for minimum resolvable temperature (MRT), a subjective test technique used to demonstrate the performance of thermal imaging sensors with human observers, is addressed. The results of automated MRT testing are presented and compared with those of traditional MRT testing for the same thermal imaging sensor. The theory of MRT as it relates to automated testing is described. The reasons for developing automated MRT testing are explored, as is the motivation for promoting acceptance of this kind of testing.<> View full abstract»
