    Perhaps because of its popularity and ease of use, BASIC tends to be looked down on by many programmers. Computer scientists condemn its lack of structure and accuse it of cultivating bad programming habits. It has the image of a language for schools, nonprogrammers and hobbyists. Here, the author details how, however, its market position believes this impression: Microsoft has just launched two new versions aimed firmly at developers of real commercial software. Many professional programmers use BASIC in an enormous range of applications-sometimes as a second language, but often for writing final code View full abstract»

  • Know-how as a product-creation, exploitation and national benefit

    Alongside engineering business based on trade in physical objects, there is also significant international business based on abstracted technological knowledge-disembodied technology as it is sometimes called. An indication of its value is that this trade exceeds the total of all international passenger fares. Even more significant is the basis that it provides for trade in derived products. Moreover, these products tend to be in areas of high technology, often opening the way to strengthened, or new, market grasp, and providing opportunities to increase added value. Here, the author describes how technical information and know-how generally are moving from being merely a necessary ingredient towards dominating the whole strength and control of much of industry View full abstract»

    The UK National Code Change in 1995 will mark the latest chapter in the short history of telephone numbering. Here, the author reviews the origins of this change, and explores some of the principles behind the choice of numbering schemes View full abstract»

  • Echelon-networking control

    Distributed manufacturing control offers more functionality than centralised systems, but normally at the cost of coordination and `intelligence'. Here, the author describes a unique solution from Palo Alto-based Echelon Corporation and its semiconductor partners, Motorola and Toshiba. Instead of simply defining a network protocol, Echelon has developed a sophisticated microcontroller (the Neuron) with networking and interfacing built in. Neuron networks can run on various media, including twisted pair, radio or power lines. The system uses an OSI seven-layer network protocol, involving three microprocessors in a classic multiprocessing environment, using shared memory as their communication link. Advanced manufacturing techniques have integrated the three processors with memory at a cost comparable with an off-the-shelf single-chip microcontroller View full abstract»

  • Ownership of knowledge-the EC Database Protection Directive

    New technologies are making information stored on electronic databases available to a much wide community than before. These databases come in a variety of media ranging from online services to CD-ROM and videotext. Inevitably, as they become such big business, questions have been raised about how they are legally protected. The European Commission has for some time been concerned that EC member states do not offer a consistent basis for protecting databases and that this may restrict or distort competition in the Community. The author explains how its response has come in the form of a draft directive, which aims to harmonise the way in which databases are protected. The directive is intended to be passed at the EC level and implemented in national laws by the end of 1992 View full abstract»

  • Solidifying fluids-the electrorheological clutch

    Publication Year: 1992 , Page(s): 348 - 349
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (176 KB)  

    Modern mechanical applications are creating a demand for faster and more controllable means of coupling and decoupling motion. The author describes one interesting approach to this problem which uses a peculiar blend of fluids and electrostatics, yielding an electrorheological clutch View full abstract»
