    The development of active-matrix liquid crystal displays (AMLCDs) to overcome the limitations of passive LCDs is reviewed. The decision of video graphics adapter (VGA) versions of these displays, the market for these displays, and the companies involved in producing them are discussed. Two alternatives to AMLCDs, one involving a method for driving passive LCDs that would give them most of the bene... View full abstract»

    The design, development, and performance of the digital micromirror device (DMD), a spatial light modulator for projection displays, are examined. The DMD covers each memory cell of a CMOS static RAM with a movable micromirror. Electrostatic forces contingent on the data in the cell tilt the mirror either on or off, modulating the light incident on its surface. Light reflected from any on-mirrors ... View full abstract»

    The use of electronic circuits in studying chaotic dynamics and control are reviewed. Since all chaotic systems have several properties in common, simple circuits are analogous to much more complicated ones, such as lasers. Consequently, the methods developed to control chaos in electronic circuits are applicable to many diverse physical systems. The controlling device itself is a high-speed analo...

    A wide variety of mathematics programs that carry out exploratory analysis data, develop new algorithms for signal analysis, and analyze a whole host of engineering applications are discussed. As a group, math programs are diverse, but large subgroups are identified, based on how they are principally used. The subgroups are: exploratory math analysis, number crunching, and general math. Current of... View full abstract»

    The latest developments in data analysis and visualization software, including extensive use of color, three-dimensional rotating graphics, representation of equations symbolically or graphically, animation, sound, and more links between data and graphs, are examined. The use of exploratory data analysis (EDA) techniques in the programs and the implementation of existing programs on different plat... View full abstract»

    Currently available data acquisition software packages are reviewed. The packages support the use of instruments to automate the sampling of analog variables, digitize the samples, and either store the results for later analysis or analyze them on the fly. A listing of the data acquisition software packages, in which platforms, requirements, and enhancements are discussed, is presented View full abstract»
