How does an aeroplane’s ‘black box’ work?

Published by:

After doing a little research, I can now tell you (basically) everything you ever wanted to know about black boxes…

In the average commercial aircraft, you’ll find the presence of multiple (usually four) microphones in the cockpit at any given time. They are located in the pilot and co-pilot’s headsets, as well as in the cockpit itself. Not only do these microphones record conversations between the pilots and cabin crew, they also record any ambient noise (such as switches being thrown or sounds generated by technical issues). The microphones all connect to the cockpit voice recorder (CVR), a master unit that stores the last 30 minutes of sound. The tape operates on a loop, essentially erasing itself every half hour.

A bone conducting earpiece, what makes it unique to other types

Published by:

Music is a large element of everyday life also it may be for almost as long as Human beings have now been on this earth. I often point to a finding of a 40,000-year-old flute dating back to that ice age as evidence for this, but truthfully, all the evidence you’ll need is all around you, every day. We remember ballads and music long after the folks who initially composed them have died and rotted away (a thought which I find curiously reassuring) plus the music industry, like it or hate it, is actually a big business.

What kinds of things do agents take with them when they’re on an job outside the office?

Published by:

You’d believe that the U . s . FBI (being the United states secret service and all) would have access to an earpiece a little bit cooler that just the conventional ‘curly cable’ job, wouldn’t you?

If pushed, We have to state that I usually imagine some old fella, like Desmond Llewelyn in the Bond movies, (or even a younger example like Ben Whishaw from ‘Skyfall’) producing all the devices himself after which explaining them to the agents before they go out and guard the President’s life.

kindle fourth-generation ebook reader cheap but nice

Published by:

Web giants Amazon.com first released their portable e-book reader, the Kindle, in 2007. For those of you who, like me, are not up to date with the latest trends and gadgets, I may need to explain what it is the Kindle actually does

The Kindle stores e-books for you to read. Plain and simple. The current model (a best seller) also includes an Internet feature that allows for access to online literary sources (e-books), which are downloaded and stored to the device’s memory. Portability and ease of use, then, are the main features of the Kindle e-book reader.  Continue reading

Keeping Up With Current Events – 2 Way Radios in Events Management

Published by:

From cultural events celebrating the diverse mosaic of British identity, to barnstorming rock n roll gigs, events management is a huge area to be involved in.

The term ‘event’ can be somewhat misleading, because technically everything is an event. Actually, when you look at it like that, maybe it isn’t so misleading after all…

When we use the term event, we could be talking about an indoor conference just as easily as a political rally. Athletic contests, art exhibitions, magic shows; if people attend it, it’s an event, and if it’s an event; it needs a manager. Continue reading

how to buy a laptop computer

Published by:

There are a great many laptops on the market; it is a very crowded marketplace indeed. This is all very well and good for the techie types out there who live on a diet of stats, acronyms and data, but what about those of us who really haven’t a clue? (And believe me, I am firmly in this category) 

Well, I recently set out to try and buy myself a laptop so that I can write whilst travelling, have regular access to the Internet (without fiddling with the tiny keys on an overpriced phone) and generally update my operations beyond late 19th century age-of-steam standards. To this end, I have talked to a couple of my more ‘technically minded’ friends and compiled for you a list of three questions that all prospective laptop owners should ask, before you get into anything even remotely technical.  Continue reading

Hotels, Holiday Resorts & Radios: A Match Maid in Heaven

Published by:

The tourism industry is a big one, with various holiday seasons bringing in huge revenues around the world, year in, year out. In some cases, tourism profits are actually vital to the survival of small towns and resort areas, as well as major factors in the host country’s GDP.

Approximately 30 Million people visit the UK from all over the world each year (and we don’t even get nice weather!). Drawn to our many sites of cultural interest, even more of historical interest, or just a slice on English country life, these tourists are actually a considerable part of our economy.

An earpiece of the action

Published by:

What’s your favourite feature of my radio accessory? In my opinion, I like the design job – It is cooler than an Inuit’s underpants!

Now for those of you who have been regular readers and posters on here, you’ll know what this blog is all about. If you’re new, let me explain.

I noticed someone last week asking on here why didn’t I write about the latest political goings-on. Well my take on that question is that there are a million websites, many of them excellent, where you can read up on that stuff and other people do it on the BBC F1 site; whereas this is the only place that, I hope, gives you unique access to what doing my job is like.

What happens when one of the earpieces stops functioning? very best solution here

Published by:

There are numerous causes for this everyday (yet absurdly frustrating) occurrence. Generally, however, it’s simply due to the loose wire and can frequently be set by pushing the wire towards the radio earpiece and, if needs be, affixing it into position with a small electrical tape, super glue, or some other adhesive.

Occasionally, if the headphones have an inline volume turn, that may be the cause. That one is just a little difficult to mend, but you could possibly always try the ‘wire trick’ described above and see if it works. If not, then open the volume controls and re-solder the wires into place (be warned, this can invalidate most warranties, so if the ‘phones are still covered, just send ‘em back and get replacements).  Continue reading
