Eraser

Whoever, during the course of his everyday job, must deal with sensitive or confidential information, such as for example credit card numbers, personal details, commercial or contractual information, knows very well that this data must be handles with the utmost care.
What often one may not know is that even though you delete this information, it is not completely erased from the memory of your computer, and might (inadvertently or not) be retrieved by third parties whose intentions may not always be honest.

Another potentially risky situation may originate from dismissed hard disk or magnetic storage supports, which are installed on a new computer or passed on to a colleague, and that may contain data, even if you think you have deleted it; this data may inadvertently circulate outside your office or organization, with unpleasant consequences.

To protect ourselves against these occurrences, we must use an appropriate secure deletion system. Before being able to reuse a magnetic storage means like a hard disk, it is advisable to perform some actions that can erase completely the stored data, making it impossible to be recovered or rebuilt at a later stage.

To do so, there is a device called HD Eraser, a machine which emits a strong local electromagnetic field. Just place the support you wish to erase (hard or floppy drive, audio or video cassette) on one side of the device, press the start button, and within a few seconds your hard drive will be completely demagnetized, and all data previously stored will be impossible to retrieve and use.

This kind of device is particularly recommended for public administration and for financial institutions. For more information on safe deletion and protection of your sensitive data, we recommend that you visit the Endoacustica website.

A bulletproof T-shirt? Nice and easy

April 29, 2010 Technology No Commenti

Bullet

Generally, when talking about bulletproof vests, the first thing that comes to our minds is certainly not a comfortable feeling. Usually, protection has a price, and often this price is paid in terms of comfort, wearing heavy armors that protect us from potential dangers but make it hard to move easily without sweating heavily.

In the future, all this could become a distant memory thanks to a research project from the University of South Carolina, which could make life much easier for those who have to wear a bulletproof vest, for example soldiers, police agents or personalities who might be exposed to terrorist or enemy threats.

In fact, scientists took a normal T-shirt, dipped it into a solution based on boron carbide, an extremely resistant ceramic material (it is the third most resistant on Earth) used in the production of bulletproof jackets. The result is a T-shirt that only at first glance looks like any other, but actually is a real armor, with the non marginal advantage of being lightweight and flexible.

Once it is immersed in this solution, the T-shirt is placed in an oven and heated, turning cotton fibers in carbon fibers. This transformation triggers a reaction which produces boron carbide. The fabric obtained is just a bit thicker than a normal one, but it is flexible and can easily be bent, unlike the standard type bulletproof vests used by police and military forces.

Furthermore, and this is particularly important for the military deployed in sunny areas such as Iraq, this fabric is also acting as an UV filter, protecting from harmful sun radiation. In the future, soldiers and police forces might be still protected, but while moving freely and without sweating, and the fabric might also be used for vehicle armors, much lighter than those currently in use.

Leica to present its first GPS digital camera

April 29, 2010 Technology No Commenti

Leica

Leica has just announced the worldwide market launch of its V-Lux 20, a compact digital camera which, along with the usual characteristics of reliability and extreme precision which one can expect from anything manufactured by the German giant, sports a new feature which makes it the first standard type photo camera equipped with GPS positioning system.

A few days ago, we mentioned a GPS photo camera, suitable for extreme sports and leisure activities thanks to its protective outer shell. This one from Leica, at a first glance, looks like a normal camera, with a 12.1 megapixel processor, a 12x optical zoom, a 3” display and a plethora of functions which ensure a perfect shot and image quality.

Each time it takes a snapshot, along with the image it also records the exact geographical coordinates of the place depicted, in order to provide its user with absolute precision in managing their image library. For example, thanks to the automatic GPS data storage, you can load the images on your social network album, and this data will automatically be added to the picture information, automatically indicating the shot location.

With these characteristics, it can be a very useful tool not only to show your friends where exactly you spent your holidays (literally!), but mostly for a professional use, for example for geographical data collection for scientific or industrial usage.

On top of that, thanks to its small size, Leica V-Lux 20 (available at approximately 700 dollars) might be a travel companion for agents carrying out a surveillance operation or gathering intelligence data, adding a further level of detail by revealing the exact geographical location of a target or of the place where information is stored.

How a Spy Phone works

April 26, 2010 Technology No Commenti

SpyPhone Symbian

The software that turns your ordinary handset into a spy mobile works in a completely invisible fashion, in order to avoid arising any suspicion in its user or alert him, so that he can keep using his phone normally and reveal all his secrets to you. This is made possible by the opportunity to control the Spy Phone remotely, by sending text messages in a particular format.

With a simple SMS you will be able to configure the spy telephone options, activating or deactivating its environmental or telephone call eavesdropping functions.
Furthermore, the spy cellphone is capable to intercept environmental conversations using the microphone to pick up sounds within a few meters range; this function can also be enabled or disabled with a text message.

During a Room Monitor call, the phone appears to be in standby mode, but if it receives an incoming call, or any key is pressed, environmental listening is immediately cut off, to avoid unnecessary attention.
This kind of eavesdropping is possible even while your spy telephone is off. In this case, a phone call from any number other than the preset controlling number would result in a “phone off” message.

The basic function of a Spy Phone, though, is the one which allows you to listen to phone calls in real time, comfortably on your cellphone, whose number has been previously set as controlling phone. When the spy cellphone is engaged in a call, it will automatically (and discreetly) send an SMS towards the controlling number, from which you will have the opportunity to call and listen in without being noticed, if the conversation is of your interest.

Of course, a spy mobile phone has many more functions. If you want to find out how it works, we advise you to visit the Endoacustica website.

Regaining your sense of balance with an inflatable vest

April 26, 2010 Technology No Commenti

Vest

Along with the sense of touch, the sense of balance, although it is not among the five basic ones, can be seriously compromised following to a disease, an accident or an injury. Rehabilitation therapies can last long, and during the therapy, the risk of a fall is always to be taken into consideration.

In order to minimize this risk, researchers from the Center for Advanced Surgical and Interventional Technologies at UCLA are working on what looks like a life vest which, if used by rehab patients, helps them maintain their balance.

It is an inflatable vest, not too different from those we can find on planes. What makes the difference is that it is inflated automatically instead of manually. In fact, on the outside the vest features some accelerometers, similar to those used on most smartphones, and some silicone inflatable balloons.

When the accelerometer detects a sudden movement which signals the danger of a fall, the silicone balloons are inflated in a way that gives the wearer an impulse that warns him against the fall, prompting him to react in the direction opposite to the one in which he is falling. The high pressure inflating of the membrane that contains the balloons works like a push which immediately lifts up the vest wearer.

The core of this system is an actuator, which provides a reaction time of approximately 60 milliseconds to inflate the balloons, enough to provide a real-time impulse. Compared to other systems which send an electrical vibration on their user’s skin, where the skin might get used to the stimulus and react slower with time, usage of balloons does not have this kind of side effects and allows for a constant immediate response, which guarantees a better rehabilitation therapy.

Recovering the sense of touch thanks to carbon nanotubes

April 26, 2010 Technology No Commenti

Nanotube

Scientific research and technology can help improve our health and make our life better, especially for those who are impaired in one of the five vital senses. In this case, we are talking about the sense of touch, which can be lost following to an accident or a disease affecting the Central Nervous System, but that can be artificially recovered, at least partly.

In fact, a research project at the Tennessee-based Oak Ridge National Laboratory seems to provide great results thanks to carbon nanotubes so thin that a glass fiber just 4 times thicker than a human hair can contain up to 20 thousand of them.

The nanotubes can basically work just like the nervous receptors covering the human skin; in fact, aside from having a microscopic size, which makes it possible to use them in such density, they are also electrical conductors.

Therefore, with these characteristics, they are a perfect solution for systems which replicate the functionality of the human nervous system. In fact, on our fingers we can find up to 2500 nervous receptors per square centimeter, a density that is in the same range of glass fibers containing nanotubes.

Each one of the tubes is individually insulated, thus enabling it to carry a single electrical pulse and increase the receptor’s sensitivity. At the moment there are no real life applications for this technology, which is still in its early stages and is now being improved to reach a high conductivity.
This project might in the near future prove very useful for patients deprived of their sense of touch, who might be able to recover, if not all their functionality, at least a significant part.

An underwater robot for hull cleaning

April 23, 2010 Technology 1 Commento

Hull BUG

Those who have been sailing at sea know well that the formation of barnacles which grow in the fissures of the hull of a boat and in the submersed part of the vessel can pose a serious threat, especially in terms of cost under the energy-saving point of view, as these formations can slow a boat down by up to 10 per cent, but on the other end, the effort to regain the lost 10 per cent can cost up to 40 per cent more in fuel.

On top of this, you should also calculate the cost, and the waste of time, to take the boats out of water for a thorough cleaning operation. All this might soon be a thing of the past thanks to Hull Bug, an underwater robot which can autonomously perform cleaning of encrusted hulls.

Developed by the US Office of Naval Research, Hull Bug has four wheels and an array of instruments and sensors on board; to get started it is placed in the water, where thanks to a sort of vacuum cleaner it would attach to the bottom of the boat to clean. At this point it starts working on its own without human intervention.

Thanks to its several sensors, it can dodge any obstacles while moving, while a fluorometric device detects the presence of biofilm on the boat. Biofilm is a concentration of microorganisms which works as a base where barnacles and parasites will grow.

At this point, Hull Bug would start its powerful brushes, an cleans the hull from any biofilm, in order to prevent formation of barnacles, rather than removing them when they are already formed. So far, tests have given positive results, and it may not be too long before we see a robot like this in any port.

Pocket video recorder, professional footage at all times

April 23, 2010 Technology No Commenti

DVR 806

To take video footage of a professional type, you do not need to tote a heavy video camera, if you have the possibility of carrying with you a small pocket video recorder that you can use in all those situations when a hidden camera pr a pocket video recorder can provide a valuable help.

For open air videos, for a bicycle ride with your friends in summer or a ski ride down a hill in winter, for hidden leisurely footage such as candid camera videos, or professional for police or video surveillance operations, using a pocket video system like DVR 806 can be your best bet.

Although it is more or less as small as a cigarette pack, it can record up to 60 hours of video, with three different resolution levels, which is conveniently stored on its internal hard drive, with a 60 Gb capacity, and can later be comfortably downloaded and played back on a PC thanks to its USB cable.

It features three different recording modes: manual, timer-activated and with an automatic infrared activation sensor. By using this mode, the miniature video recorder will work while you are away, fo0r example to protect you against unwanted guests at home, or if you suspect that something wrong might be going on in the office during your absence.

By connecting it to the power mains, you will have at your disposal a real fixed surveillance camera, which you can use for unlimited recordings (compatibly with capacity of its hard disk and additional memory card). If you use its built-in lithium battery to power it, it will be your perfect companion for your excursions or your sport activities!

A biometric wallet protects credit cards and personal data

April 22, 2010 Technology 1 Commento

TungstenW

If you need to take your wallet with you at all times, you have to make sure that it is fully protected against unauthorized access or theft, especially if contains not only cash, but credit cards or sensitive data which might be used to give us a bigger trouble than the loss of a few hundred dollar bills, such as for example identity theft and the like.

To protect ourselves against this kind of unfortunate events, without leaving behind the good old wallet and its contents, now we can use Tungsten W, the world first biometric wallet. As you can easily guess by the name, it is made up of a metallic shell in highly resistant tungsten; the wallet can be opened through a small biometric scanner, which will recognize your fingerprint, and only at this point will open it granting access to your cards, documents and cash.

To start using it, you will need to connect it to a computer to configure it by storing the fingerprint which, from that point on, will work as an access key. Along with this, Tungsten W is also equipped with Bluetooth connectivity, to pair it to a mobile device like a phone, which will inform you through an alert as soon as you exceed a certain distance from your wallet, for example if someone is trying to steal it.

The biometric wallet is available in a wide range of versions, not only in tungsten but also in carbon fiber or Kevlar, and in 5 different colors, at a price that ranges from a minimum of approximately 400 dollars to 600 dollars for the Kevlar and carbon fiber version. With this price tag, its content must be really precious to justify such an investment for a wallet…

How to tell an enemy by the eyes

April 22, 2010 Technology No Commenti

Panoptes

A research project carried out by Southern Methodist University in Dallas, with funding from the US Dept. of Defense, is working on a new technology for photo and video miniature cameras, which thanks to its high resolution can identify enemies even inside a pitch black cave; this technology, named Panoptes, is also used in the development of an iris scanning system, used to identify people and which can help towards an improvement of security procedures in sensitive places such as airports, military installations etc.

The name Panoptes comes from the mythological giant with 100 eyes, and suits well a technology capable of producing images of extreme clarity thanks to an array of micro electromechanical mirrors, integrated with low-resolution paraboloid-shaped sub-imagers, which are used to zoom on a specific area of interest.

The target of this research project is to produce miniature lenses which can be mounted in tens or hundreds on a soldier’s helmet, connected among them and in turn to a computer that processes the images and manages the overlapping, providing a result of extreme clarity without the weight of a bigger lens.

Furthermore, always by using the Panoptes technology, researchers are working on a system called Smart Iris, capable of scanning someone’s iris, without them having to waste time stopping and staring into a scanner. This system could provide a valuable help to protect potential terrorist targets such as for example an airport: just place it into a doorway or metal detector, and the passenger’s eye will be quickly analyzed, without wasting time and without raising any suspicion, speeding up filtering operations and granting access only to authorized personnel.
