    The development and present day capability of the Kent organization are traced from the early days of a Victorian entrepreneur who had the vision to realize the potential of flow measurement in industrial and domestic fields, to the present international network of companies with a product range extending from inexpensive mechanical water meters to computerized process control systems using the la...

    The error performance of multi-transmitter data systems is described for mobile and stationary users in overlap areas, as a function of carrier frequency and modulation timing difference. Plots of bit error rate and error distribution are given, and the conclusion is reached that performance is comparable to single transmitter systems at the same signal level. The constraints on the choice of data... View full abstract»

    The Multi-Role Combat Aircraft Tornado is probably the most spectacular example to date of a complex man-machine system in which design and manufacture are widely dispersed. Even sub-assemblies of this system are extremely complex relative to the technology of just a few years ago. This makes life extremely difficult for an engineer involved in the procurement of the sub-assembly, especially as th... View full abstract»

    The evolution of the `portable¿ or `benchtop¿ digital tester is briefly discussed in this paper in terms of the primary `drivers¿ which lead to its development. The analysis of three current `representative¿ portable digital a.t.e. system architectures is then provided and the impact each has on the six major functions common to any a.t.e. system design is briefly discussed. The paper also add... View full abstract»

    The output voltage obtained from a recording tape used in a high density digital application has been shown to be characterized by simple parameters. These parameters have been investigated and predicted to contribute to the signal-to-noise ratio expected from the tape and consequently the error rate obtained from a recording system using it. Measurements on a recording system gave confirmation of... View full abstract»

    Details are given of how magnetic field strength varies throughout a short section of a 1500 m long tunnel fed by a leaky feeder. Both phase and amplitude are examined. A second series of measurements examines in detail the phase variation along a single line down the tunnel over a distance of 500 m. The results enable judgments to be made about the potentiality for postion fixing in a tunnel usin... View full abstract»
