    Legislation is driving electronics companies to prepare for products for later recycling. The effort foreshadows a future in which most of the content of obsolete electronic products will be reclaimed. The author discusses the green port concept for being developed by a consortium of European electronic equipment manufacturers who are responding to proposed legislation. Through a green port instal... View full abstract»

    Across-the-board recyclers can keep discarded electronic products out of landfills by identifying and extracting component parts for resale and materials for reprocessing. The complete recycling of electrical and electronic equipment will in the future probably be handled by independent recyclers who become specialized in understanding the varieties of discarded equipment. They will plan the logis... View full abstract»

    Mirrors grown in the crystalline structure ease manufacture of vertical-cavity lasers, which emit collimated circular beams and can form large two-dimensional arrays. The authors discuss the fabrication of the surface emitting laser mirrors. By means of techniques such as molecular beam epitaxy and metal-organic vapor phase epitaxy, hundreds of layers of semiconductor materials can be grown one on... View full abstract»

    Autonomous underwater vehicles (AUVs) are shedding their testbed origins and finding homes in marine science, ecology, offshore oil, and naval operations. The transition is being aided by improved controllers and energy sources. The author discusses the developments of AUV systems and describes some of the AUVs that are in operation. The various applications of AUVs are also discussed.<> View full abstract»

    Pioneered in Japan embraced in Europe and the United States, the engineering discipline of mechatronics seeks to design optimum performance into subsystems of electromechanical products. Mechatronics is the synergistic combination of precision mechanical engineering, electronic control and systems thinking in the design of products and manufacturing processes. The author examines the benefits of m... View full abstract»
