    The design and evaluation for a display of a four-dimensional perspective flight-path predictor (X, Y, Z, and time) are described. Five basic principles of human performance are used to guide the choice of display configuration: (1) working memory limitations; (2) object integrality; (3) compatibility; (4) consistency; and (5) visual momentum. Each principle is discussed along with the correspondi... View full abstract»

    An expert system used for model reduction is described. The system is a useful tool in the heuristic optimization of approximate model design. A set of rules for selection of the appropriate approximation algorithms has been derived from experience. The approach represents a novel way of formalizing rules in order to obtain optimal reduced-order models. The expert system (EXPRED) has been implemen... View full abstract»

    The design and development of an automatic assembly machine for microelectronic components is described. The machine uses multiple microprocessors to accomplish its tasks, which include process supervision, visual pattern recognition, and information display. The system is flexible and reliable due to its modular design and the use of a structured supervisor with diagnosis capability. It minimizes... View full abstract»

    The goal of this investigation is the development of an adaptive drug delivery system for use in regulation of critical care patients suffering from cardiac failure. It is assumed that adaptive control algorithms combined with expert system techniques are necessary to maintain stable patient statues within narrow physiological bounds in the presence of large plant uncertainty, and a hybrid control...

    The development of a workstation that integrates design, analysis, and simulation methods used for flight control system synthesis is described. Aerodynamic, propulsion, and structural models interface directly for analysis and synthesis work. The results transfer to a flight simulator and to the dynamic structural model. The workstation is implemented with an executive, which handles most input-o... View full abstract»

    Eigenstructure assignment for linear systems is basically an inverse eigenvalue problem. Two possible solutions to this problem that have been implemented on the Ctrl-C commercial design package are presented. One is a least-squares approach, and the other is an iterative method. Both algorithms use singular-value decomposition and produce robust (well-conditioned) answers to the state-feedback po... View full abstract»

    Implementation aspects of a self-tuning motion controller, which uses the Texas Instruments TMS32010 digital signal processor (DSP) chip, are described. The potential advantages in using a DSP chip include reduction in operation time, development time, and cost. The self-tuning controller can track variations in system parameters as well as system disturbances. Algorithms are described, experiment... View full abstract»

    A machine called STENEX, which is intended to be used as a stenography machine for the blind, is described. The blind stenographer can enter material very fast, and voice feedback of the input material is provided to ensure accurate entry. All that is entered is stored in computer memory and it can be recalled, through a search memory, with voice output. The text record can be turned into written ... View full abstract»
