BEAR, a robot to rescue wounded soldiers and not only

November 25, 2010 Technology No Commenti

The U.S. Army researchers are working to test a new robot, designed by Vecna Robotics, which would be used to recover and rescue wounded soldiers during combat. The robot, called BEAR (Battlefield Extraction Assist Robot), can spot a soldier in trouble thanks to its sensors and its cameras.

BEAR is controlled remotely via a special glove that allows the use of simple hand gestures to operate it, to make it approach the wounded soldier, pick him up from the ground and take him as soon as possible to the nearest medical point.

The rescue robot can carry a load of about 230 kg, lifting it gently with its hydraulic “arms”. With a height of about 1.80 m, BEAR can also inspect any area behind a wall, or lift its load on a raised surface. The arms are equipped with “hands” that can carry out precision tasks, ensuring that a wounded soldier will be treated with care and not moved abruptly.

Moreover, thanks to these features, BEAR can be used not only for rescue operations, but also for reconnaissance and surveillance, to transport explosives or hazardous materials that must be handled with care, or to inspect parcels which could conceal a bomb, defuse a mine, all this without putting human lives at risk.

The simulations and tests on BEAR are going on since about a year, and also include the development of a new iGlove, the glove used to control it, which will allow for a more precise control and for the ability to send advanced instructions, for example when defusing a bomb. In addition, the future version of BEAR will have several autonomous functions, which can be carried out without human intervention.

For leisure, for business and not only: digital micro recorders

November 24, 2010 Technology No Commenti

Until a few years ago, the only ones to use a miniature audio recorder, of the kind with micro cassette tapes, were journalists, and many times we happened to see one only on television during an interview with a politician, a celebrity or a sportsman.

Nowadays, not only audio cassettes, but also compact discs, are obsolete audio media, and have been replaced by digital media and memory cards which provide for a much larger storage space and ease of use, all this teamed up with a much smaller encumbrance.

Thanks to this, the world of audio recording as we know it today is totally different than it was a few years ago.

Now, with devices that are small but highly powerful, yet flexible and very easy to use, the ones that use a digital voice recorder are no longer only journalists, but many other types of professionals: managers may want to use it to record an important meeting in the office; students can take notes in audio format, or simply record their teachers during a lecture; private detectives and police officers, thanks to a digital recorder which comes in microscopic size, are able to gather evidence against a criminal or an unfaithful spouse, and use them as decisive evidence before a court of law.

These of course are just a few examples, but the bottom line is that digital technology of the twenty-first century is now present in many fields, and if used in the right way, may prove useful not only at work, but also in leisurely opportunities.

To find out the various models of digital micro recorders available in the market, and their different characteristics that make them suitable for professional use, for leisure or for investigation and surveillance, we recommend that you visit the Endoacustica website to find the right model for you.

A new helmet to protect U.S. soldiers’ faces

November 24, 2010 Technology No Commenti

For U.S. soldiers deployed on the frontline in war zones, danger is always around the corner, in the form of an IED (Improvised Explosive Device), an ambush or a sniper. The most common effect of these threats is represented by the injuries sustained by soldiers, and of all wounds, the most dangerous ones are those which are not visible, ie those caused by head injuries or concussions.

Modern helmets provide adequate protection to the skull, but to protect the head, one often forgets that the face is exposed. To overcome these shortcomings, researchers at the Massachusetts Institute of Technology are working to create some sort of shield to be applied to helmets, which by increasing the protection for the user’s face, can similarly reduce the risk of head injury.

This sort of helmet shield, has been developed by the Department of Aeronautics and Astronautics, by analyzing via computer simulation the different consequences on the soldiers’ skull caused by exposure to explosions without a helmet, with an ACH (Advanced Combat Helmet) or wearing one with a transparent polycarbonate shield. In the latter case, the shock at brain level was significantly lower.

So far, the test was conducted by using only one scenario, involving an explosion taking place in front of the soldier. In the future, other tests will be made, simulating explosions of varying intensity, distance and angle, so as to measure the consequences, for example, in the neck area, and find ways to provide adequate protection to that part of a soldier’s body.

Obviously, everything is still in the planning phase, and the shield is not yet in production. American soldiers at the front look forward to the day when they will be able to use it to protect their faces from enemy threats.

Defense from telephone harassment, with a voice changer

November 22, 2010 Technology No Commenti

Stalking is a phenomenon that we often happens to read about on papers, when we see reports about of annoying fans of actresses, singers and celebrities who follow them everywhere, harassing them by phone and in some cases even reaching extreme consequences, with attacks such as the one that claimed the life of John Lennon in 1980.

Unfortunately, however, it is only famous people who can fall victims of this kind of harassment: every day we can see news about rejected ex boyfriends who attack their ex, or they “simply” call them on the phone at any time, day and night.
To protect oneself against this kind of occurrence, there is a simple and painless way that does not even require changing your phone number or even your home address: Just change your voice!

This is made possible through the use of a voice changing device, a simple box which, when connected to your home phone or your mobile handset, works on the frequencies of the human voice, so that when you speak normally, your counterpart on the other side of the receiver will think that they are talking to someone else.

This device, in fact, can change the voice in an absolutely natural and clean way, with no metallic tones, making you sound like a man, a woman, an elderly or young person, or even a child: a great way to protect yourselves from telephone harassment, not only of this kind but also by annoying creditors or telemarketing companies, without having to hide or change your address.

To find out in detail how the voice changer works, and discover the range of available models, as well as several items for protection of your privacy, we recommend that you contact Endoacustica, an industry leader with many years of experience in the security field at your complete disposal.

Looking around corners thanks to a laser beam

November 22, 2010 Technology No Commenti

To many of you, the term femto-photography will sound quite strange and meaningless, and to be honest, even your humble blogger had never heard it before, or at least, before an article appeared on the BBC defining it as a form of photography that uses the speed of light to create so-called “light echoes” and use them to photograph objects hidden from direct view, for example behind a corner.

According to this principle, the light that shines on an object and defines its shape can “bounce” around it, and based on this idea, a research group at the Massachusetts Institute of Technology has created a kind of laser camera that using high-intensity and short-wave frequency laser beams, can manage to capture this light.

In this way, the camera is capable of discerning the shape of an object outside its direct viewing field, using a wall or door as a kind of “billiard bank” to get a view that its creators dubbed as similar to that of X-rays, but without radiation.

The technology that makes this possible is based on a laser that can fire a laser beam in pulses that last only a quadrillionth of a second, flooding the scene with light particles that start bouncing around the room or environment that you are trying to view.

By collecting these fragments of light that bounces off the walls, it is therefore possible to rebuild, at least in part, the image of what is inside the room without having a direct view; once the right way is found to obtain the whole image, the system could be used for example for fire rescue operations, or on a smaller scale, for endoscopic surgery.

It looks like a phone outlet, but it is a bug

November 20, 2010 Technology No Commenti

As we have seen in dozens of spy movies, when a secret agent or a police officer wants to intercept phone calls of a suspect or an enemy spy, one of the most common tricks is to pose as a telephone company worker, or an electrician, and sneak into their target’s apartment or lobby for a supposed “repair” that only serves the purpose of planting a bug or a hidden microphone.

Nowadays, if on hand, for mobile phone interception it is not always necessary to be physically near the phone itself, but all it takes is the right equipment to pick up the conversation through the airwaves, for interception on landlines, you still need to resort to tricks like the ones seen in movies to plant a transmitter on the telephone line wires or inside the home handset.

In this sense, the use of a telephone bugging device concealed, for example, on the phone jack, allows you to listen to conversations taking place on all phones that use that line, and through its small UHF transmitter hidden inside the outlet, to transmit the intelligence via radio to a listener stationed at a safe distance and with a suitable receiver.

The UHF transmitter, among other things, is powered directly from the small electricity flow running through the phone line, so there is no need to change batteries or worry that they may run out.

For more details on the various types of phone bugs on the market, and to find the one that best suits your needs in the audio surveillance field, you can visit the Endoacustica website, and contact our consultants who will surely help you choose the right tool for you.

No annoying cell phones, thanks to a handkerchief

November 20, 2010 Technology No Commenti

For once, since it’s Friday and the weekend is coming, we want to allow us a little “light” diversion, talking about an item which, more than having a true utility function, has a “diplomatic” one, so to speak.

It is called Phone Kerchief, and it basically is, yes, a handkerchief that you can use to cover your phone. Thanks to the particular material of which it is made up of, the tissue is able to block the phone signal, preventing it from working and allowing its user to devote full attention to their counterparts or to an important meeting.

As a further sign of courtesy, the Phone Kerchief also has a small embroidery that reads “My phone is off for you“, which the wearer can use to communicate to the person in front of them that their conversation is more important than any incoming phone call.

Of course, the first thing that might come to anyone’s mind ask is that maybe, instead of spending $60 for a handkerchief in shielding material, it may be wiser to save a few bucks and turn off the phone with a simple gesture, but you know, marketing’s ways are not always so rational…

If you need to block all mobile traffic within a certain environment, such as a conference room during a meeting or a private negotiation, then it is surely wiser to use a much more advanced, although less “diplomatic”, technological support such as a jammer, which can block incoming calls as well as outgoing; a jammer is certainly much safer and more effective than the use of a simple handkerchief, and it also prevents prying ears from hearing the contents of your conversations.

Laser microphone for remote listening

November 18, 2010 Technology No Commenti

As we have seen in a recent article, law enforcement officers working on investigation activities do not always have the chance to come close to their suspects to gather information, install miniature cameras or bugs to eavesdrop on conversations and so forth, to avoid putting their own safety at risk, or jeopardizing the whole operation.

To avoid taking unnecessary risks, but still be able to intercept conversations that take place in a closed room, there are alternatives provided by modern surveillance technology, for example such as laser microphones.

A laser microphone, as the name suggests, uses an invisible laser beam that is pointed at a window glass, up to a maximum distance of more than a mile. This beam is able to “read” the vibrations of the glass itself, vibrations caused by sounds and voices coming from the room and behind the window.

The laser beam reflected on the glass, is subsequently picked up by a receiver located at the right angle to meet the reflection. The receiver, combined with a decoding system, is able to convert the laser pulses, as influenced by the vibrations on the glass, into sounds and voices, with great clarity of sound, so that you can listen to them in absolute security, and determine what happens behind that window.

The use of this technology by law enforcement has proved most useful in investigations on organized crime, and operators gave a positive feedback on it, mainly because it makes operating conditions much safer.

Robot snake, kill it and it will multiply

November 18, 2010 Technology 1 Commento

When we were kids, in the countryside, we all played with earthworms, amused at how killing them by cutting them in two would have no success, and it would actually end up creating two of them. Apparently, the Israeli military researchers seem to have been inspired by earthworms to create their snake robot.

In fact, if you try to neutralize it, by shooting or throwing a grenade, each one of the segments that make it up will become independent and continue to move on its own and do its job, just like some sort of high technology worm.

Each one of the small robots is equipped with a processor that serves as “brains“, an array of sensors, a motor and batteries to provide power. As long as the various segments are joined together, the robot can be used for example for climbing trees or walls, inspect pipes, underground tunnels (such as those used to smuggle weapons into the Gaza Strip), or otherwise to carry out missions in places difficult to reach with traditional video surveillance systems.

Each of its modules can be configured and programmed to perform different tasks, including planting a bugging device, collecting pictures or leaving a bomb. Should the snake be attacked, any explosion would result in the separation of each one of the individual modules, which would at that point carry out the missions for which they were individually programmed.

The standard version of the snake robot weighs about 6 kilograms, but the weight and length can be increased or decreased by simply adding or removing segments, depending on the mission you want to accomplish.
Currently, it has been presented at the Israeli Conference on Robotics, but it is still in its testing phase, and once completed, mass production will begin for use by the Israeli Defense Forces.

A watch to spy on those around you

November 17, 2010 Technology No Commenti

Often the best way to hide something is to keep it right in front of others, or if it is a very small object, to hide it in a visible place, where nobody could ever think about looking for it, because it would be too obvious.

This principle is applied very often when we talk about surveillance, with bugs and transmitters hidden in everyday objects where no one would look for a hidden microphone.

For example, this is the case with the GSM Watch, a watch, as the name suggests, that can also function as a phone, thanks to the housing inside which can hold an ordinary SIM card. The GSM Watch is connected via Bluetooth to a few other miniaturized devices, such as a micro earpiece to be placed inside the ear canal and a necklace, with a pendant that contains a tiny microphone.

These three items together form an awesome system for remote listening that allows the wearer to pick up, through the microphone on the necklace, all sounds and voices around them, and to transmit them remotely, to a preset phone number, thanks to the SIM card contained inside the watch.

Those who are on the other side of the phone can then listen to what is happening without anyone noticing, and in an equally discreet way, send instructions and operational information to the wearer of the earpiece. With this full system, you can gather information in real time, send them to the outside world where they will be analyzed and from where one can determine the best course of action to be followed in situations such as a confidential meeting, a difficult negotiation a police investigation.

For more information on the possible applications of GSM Watch, you can visit the Endoacustica website where you will find an array of articles for discreet intelligence and information gathering.
