    Researchers usually implement fuzzy inference systems in software on digital computers or microprocessors. This approach copes with most problems, however real-time systems often require very short time responses. In this case, a hardware implementation becomes the only solution. This 1.5-μm CMOS implementation uses a current mode circuit to generate input membership functions and processe... View full abstract»

    Neural networks and related techniques are powerful tools that prove their efficiency in real-world applications, where problems are badly defined or difficult to formalize. Some applications, especially those involving images, require a huge number of operations and an enormous reduction of the dataflow from input to output data. For sorting objects by vision or image analysis, for example, input... View full abstract»

    The manufacturer places a warning against improper use on the underside of my keyboard. The warning begins “Continuous use of a keyboard may cause repetitive stress injuries (RSI) or related injuries.” Later it says, “If you feel any aching, numbing or tingling in your arms, wrists or hands, consult a qualified health professional.” This is serious stuff. The potential heal... View full abstract»

    E-Data Corp. is a company apparently solely in the business of trying to make a buck out of a patent that it bought. Its efforts to make the software industry salute, or at least pay attention to, its Freeny patent (US Patent 4,528,643, issued July 9, 1985) on selling software via the Internet have provoked rage, amusement, and even some actual licenses. This paper discusses E-Data's licencing eff... View full abstract»

    Describes a resistive network combining constant and controlled resistors, as well as its implementation with MOS transistors. This circuit synthesizes nonlinear functions of several variables. We can consider it an implementation of fuzzy rules, since its constituents serve as membership functions, fuzzy logic gates, and center-of-gravity defuzzification circuits. Alternatively, we can consider i... View full abstract»

    The Innovative Systems Design Group at SGS-Thomson Microelectronics has been exploring analog implementations of neural network architectures with special emphasis on efficiency, precision, and large-scale implementation. We are developing three large-scale analog VLSI chips, all of which work on image-processing problems. Because of their efficiency and regularity, analog computing arrays form th...

    Drawing inspiration from the structure of shark skin, the authors are building a system to reduce drag along a surface. The entire question of active control of shark skin is speculative. Biologists hypothesize that sharks actively move their denticles. Indirect evidence of this is twofold. The denticles connect to muscles underneath the shark's skin. The total number of mechanoreceptive pressure ... View full abstract»
