Globalisation, coupled with the accessibility of the Internet in the modern world, can result in things meaning very different things to different people. Common terms can be misused too; we have seen some very interesting interpretations of meanings in our various lifetimes! We have decided to put a lexicon on the website so we can keep the pages tight to the usually defined and abbreviated form. Apologies if that makes them a little awkward to read. Rather than a straight glossary, herein is a lexicon to aid better the background as often a little more context is needed in this highly specialist field and easily stated, yet difficult to actually do set of technologies and problems.

This is not going to be exhaustive, but will list many of the acronyms and areas where an explanation is best served. We will assume most of the common Telecommunications and Military Signals terms are standard, for the avoidance of doubt we will always use the UK meaning. If we choose to alter that to a NATO or other jurisdiction then it will be listed below. Feel free to Contact Us to ask us to update this page with something we haven't yet put on here.

The common Electronic Warfare acronyms are excluded.

The following links are the various pages in alphabetic order for our site's use of various abbreviations and our intended meaning, {use the links to relevant pages}:

GDP - Gross Domestic Product. This is a country-level monetary measure that equates to the final value of all goods and services produced by that country in any given period or year. This is not the total sales within a country as that would therefore include a misleading element of the business-to-business transactions. Without over-simplifying this, if you made an item that was £175 yet it contained £75 of items you acquired from other businesses then the GDP would in essence be £100 not £175 for every item produced that period.

HMI - The Human Machine Interface. This can be literal as keyboard, mouse and display monitor. We mean it to be the widest sense of interaction, including biofeedback [such as Haptic] or 3D lithographic projection and virtual interaction.

HPC - High-Performance Computing. Colloquially called supercomputing. We mean all branches of highly parallel, hypercube, heterogeneous super-clustering and various other forms.

HR - Human Resources.

HUMS - Health and Usage Monitoring System.

HV - High Voltage. Defined as greater than 1,000V AC or greater than 1,500V DC. Scientists and Electronic Engineers would consider those somewhat high! Hence this is somewhat a relative term. For the avoidance of doubt the AC voltages are root mean squared and the figures quoted are between conductors [not to earth which reduces the figures quoted]. See BS 7671.
