Take Up Thy Stethoscope…. and Listen, in secret

dicembre 21, 2009 Technology No Commenti


How many times did we find ourselves wishing we could listen to what our colleagues in the next room are saying, to find out what they really think about us? Or that we could spy on our annoying neighbor to expose his strange (or even illegal) habits?

In many cases, having the chance to listen to what is said behind a wall can be useful not only to protect yourself in cases of office power struggle, or to make sure that your spouse is really faithful, but also to prevent or expose corporate espionage, or even to frame dangerous criminals.

To do it securely, modern technology lends us a hand, thanks to wall microphones, the digitally enhanced version of our doctor’s stethoscope; in fact, in most cases, this kind of microphone is made up of a stethoscope, connected to a small but powerful amplifier which augments its sensitivity and allows the stethoscope, by analyzing the vibrations caused by human voice against any wall, to listen to what is being said in the next room.

For an even more accurate listening operation, you can use a window microphone, that is, a transmitting device which, when placed on the outer glass of a window, uses the same principle to read vibrations of glass and intercept conversations behind it, transmitting them towards a receiver placed up to a few hundred meters away.

As you can imagine, this particular kind of devices is more suitable for professional users, such as detective agencies or law enforcement, or in any case, for people who want to get the best out of their eavesdropping operation, while minimizing any possible risk connected with planting hidden bugs.

New camouflage suits for the British Army

dicembre 21, 2009 Technology No Commenti


The BBC has reported yesterday that the infantry of Her British Majesty’s Army will be equipped, starting from the month of March 2010, with a new camouflage suit that will replace the one that has been used for more than 40 years without any change.

The MTP (Multi terrain Pattern) model, identified by number 40, will gradually replace the old model number 8, called DPM (Disruptive Pattern Material), which will be out of service within 2011, the scheduled time limit for the entire Army to be upgraded.

The new camouflage suit will initially be used in the Afghan theatres of operations where the British Army is deployed. In certain areas where Her Majesty’s soldiers are on duty, the terrain’s morphology can dramatically change within a few miles, therefore a suit which works well in a green zone may turn out useless, if not dangerous, in desert areas where the predominant shade is grey.

The new suit is a good compromise between a terrain-specific kind of design and an all-rounder suitable for diverse environments. Afghanistan, under this point of view, is a harder challenge than Iraq, where the soldiers’ uniforms are mostly woven in colors suitable for hiding on sand.

It has been tested on various terrains in different parts of the world (including Afghanistan itself) before the final approval went to Model 40. The soldiers who have participated in the tests have given an extremely positive feedback, as according to their experience, the new camouflage suit will “make it harder for them to be seen, making their job easier”.
