    Electrochemical sensors a modern success story for an old idea (1994)
    Bradford : Emerald
    Sensor review 14 (1994), S. 30-32 
    Details
    ISSN: 0260-2288
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Looks at modern electrochemical gas sensors: they way they workand the range of gases they can detect. The largest application area is inportable gas detection equipment where the emphasis is on small size and lowpower demands. These sensors are also used for emissions monitoring,specifically from combustion sources. Concludes that portable multigasdetectors will continue to get smaller with a consequent reduction in size ofsensors and that a wider range of gas sensors will be available with advancesin electrochemistry.

    Notes: Looks at work carried out by The Centre for Manufacturing Metrology atBrunel University into developing new probes for high precision dimensionalmeasurement. Describes the conventional "touch-trigger" probe and theerrors in its performance. Also describes three prototype probes all based onfibre optic principles: a two dimensional Triggering Probe; a threedimensional Analogue Probe and a non-contact probe. Concludes that the2-D triggering probe is a simple construction but limited to2-D operation; the analogue 3-D is smaller in comparison withexisting types, comparable in accuracy and cheaper to manufacture, and thenon-contact probe has potential for future development with some formof "intelligent" data processing.

    Notes: Describes the increasing need for simple and efficient antennas andlooks at the performance of quarter wavelength and helical antennas.Concludes the optimum performances from both antennas are ruled by the choiceof a suitable ground plane. The helical antenna is capable of producing acircularly polarized field, whereas the quarter wavelength antenna producesonly linearly polarized fields. Both types exhibit low efficiency, with thehelical antenna being less efficient owing to its short structure.

    Notes: Examines the problems of applying fuzzy logic to control applicationswhere each application is different from the previous one and looks at thedevelopment of a unique system of fuzzy logic based on an existing softwarepackage. The system comes in two alternative forms; the first is a fullyconfigurable fuzzy set for the OEM designer which, for example, could be usedto control the temperature of a large oven and the second reduces the fuzzyfunction down to the most basic level where no process knowledge is required.Describes the tests carried out in order to determine the linguisticvariables which apply to general control applications. Concludes that fuzzylogic begins to take effect in those situation to which normal controlalgorithms PD, PID functions have difficulty adjusting.

Continues with an examination ofother sensors used in photosynthesis research and measurement techniques usedfor other plant science research such as plant stress. Concludes with recenttrends and applications in plant science research and lists some areas ofresearch applications including studies of climatic change, pests anddiseases and plant breeding.

    Notes: Describes a semi-automated electronic board assembly station withcut-and-clinch technology. Examines the system's optical correction facility which can correct for component hole registration variations and can also be used for the verification of new assembly programmes and the removal of digitizing errors. Concludes that the system provides manufacturers with highly flexible automation for assembling PCBs, with a consistent and repeatable performance.

    The "electronic nose" using conducting polymer sensors (1994)
    Bradford : Emerald
    Sensor review 14 (1994), S. 28-31 
    Details
    ISSN: 0260-2288
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Outlines the development of an electronic nose for general applicationand examines it's three major parts: a sensor array, a means of converting the sensor outputs into suitable signals for analysis, and a software analysis tool. Describes the sensor array, electronics and overall system design, the conducting polymer sensors and the computer hardware and software. Discusses the analysis techniques and results of tests carried out on various gases, vapours and liquids. Concludes that although much further work is required into sensors and analysis techniques it is anticipated that a growing number of companies will become interested in developing these systems.

    Notes: Describes a biometric security system, the EyeDentify retinal scanner,which works by mapping the vascular pattern on the retinal portion of theeyeball, using a specially designed camera. Outlines the three modes of theretinal scanner: enrolment, verification and recognition and theuniqueness and stability of retinal identification. Concludes that owing tothe unmatched accuracy and ability to run in a time "recognition" mode, retinal scanners are utilized in the world's most secure areas.
