A perfect wireless signal even in remote areas

novembre 9, 2010 Technology No Commenti

Anyone who found themselves away from the nearest sign of civilization, for example in the mountains or on a remote island in the middle of the ocean, knows perfectly that even trying to use a mobile phone could be a major problem because of lack of network signal. Just imagine how one could ever think of connecting to a wireless network.

To solve this problem, and ensure wireless coverage even in the remotest corners of our planet, Fujitsu unveiled its GaN-HEMT project, a new power amplifier that has reached a record level of output for wireless radio and telecommunications.

Thanks to this wireless amplifier it will be possible to multiply the power of a wireless communications system up to six times the current level, managing to bring the wireless signal in areas that are currently cut off from the network because it would be impossible to lay down optic fiber cables.

The GaN HEMT (Gallium Nitride High Electron Mobility Transistor) system is able to provide a transmission speed of about 10 Gbps, a speed at the same level of the best optical fiber networks.

So far, laboratory tests at Fujitsu have succeeded in developing a power of 350 milliwatts using amplifiers of this kind, operating on the C and Ku bands which, unlike W-band millimeter-wave transmissions, do not suffer significant loss of power caused by weather, for example during a tropical storm that could greatly reduce the signal strength on a remote island.

In the coming months, the engineers at Fujitsu will work to improve the signal strength and stability, using this technology to create trunk lines that would carry high-speed wireless signal to provide an access without geographical limits.

A bug that starts by itself

novembre 8, 2010 Technology No Commenti

Those who work in the surveillance field, such as law enforcement officers and private investigators, know that during an environmental eavesdropping operation, the amount of time occupied by background noises and useless sounds far exceeds that of conversations actually useful to the investigation.

For example, when planting a bugging device in an office, it may happen that the person under surveillance is not talking to anyone for long hours, and the eavesdropping operation would return only background noise, such as typing on a computer keyboard.

This kind of sounds make the process of listening to the information collected a long and tedious job, and especially if the bug is battery powered, it could run out of juice without giving real results. Therefore, care should be taken to optimize the operation of surveillance devices, using a tool such as a voice-activated bug.

This kind of bug, thanks to its activation sensor, can start working only when the sensor detects a sound above a certain threshold, thus avoiding to record and transmit background noise instead of real intelligence.
It is a GSM bug, with a SIM card just like that of an ordinary phone, which is used to transmit sounds and voices to a preset phone number, at any distance, even on the other side of the world!

The programming of its features (sensitivity, activation alert and so on) can be conveniently done via SMS, thus ensuring absolute safety. By connecting the GSM bug to the landline phone cables, you can easily listen to all incoming and outgoing calls, automatically starting to listen when the handset is released.

Finland, a 3D speed camera fines you in seconds

novembre 8, 2010 Technology No Commenti

Scandinavian countries are often taken as a benchmark for the accuracy and honesty of their citizens, especially when they get behind the wheel, a situation in which they tend to show their respect for other drivers, for speed limits and for safety on the road.

Obviously though, not all of them comply with these rules. Precisely for this reason, in Finland, which has always been at the forefront of technology (think of Nokia, for example), the highway police has just been equipped with cutting-edge traffic cameras, able not only to detect when you are pushing too hard on the gas and exceeding the speed limit, but also to check your insurance and even tax situation!

This futuristic speed radar features cameras which, in addition to measuring speed, can also read the license plate number. Connected via satellite to the police database, the system checks that the car insurance associated with that number has been regularly paid, and even if the car owner has unpaid taxes or fines.

Also, the three-dimensional cameras of this advanced system, called ASSET (Advanced Safety and Driver Support for Essential Road Transport) and funded with about 8 million euro from the European Union, are able, thanks to their sensors, to take pictures of the inside of your car, to verify that the driver is wearing the requisite seat belt. Thanks to its sensors, then, it can also detect other violations, such as the non-observance of safety distances, which can often cause fatal accidents.

The Finnish authorities are hoping that such equipment will further increase road safety by reducing the number of accidents caused by speed or risky behavior, in a country which anyway is always on one of the top positions of the worldwide ranking for road safety. But you know that on the road, caution is never too much, even in Finland.

A bug can hide in the power outlet

novembre 4, 2010 Technology No Commenti

When you think you are safe in a protected environment, you let yourself go, and mistakenly believing belief that no one can hear you, you may end up revealing details which, if heard by someone else, may be highly compromising for anyone who has something to hide.

Whoever is afraid that their words could be intercepted, for personal or business reasons, should carefully check their environment, to make sure that their workplace or home are not concealing devices that can be used for secret listening by unauthorized parties or, for those who have something to hide, by the police.

Sometimes, though, checking carefully everywhere may not be enough to find bugs, or hidden transmitters, if they are well concealed so as not to generate any kind of suspicion, for example by placing them inside everyday objects, where one would never think that something fishy can hide.

A desktop calculator can hide a secret microphone, a pen may contain a camera, inside a computer mouse there could be a bug and so on, even hiding a GSM bug in a multiple power outlet, just like the ones that everyone has at home to power their computers or TV sets. By concealing a bug, connected to a SIM card, into a power outlet, there are two benefits for the surveillance operation.

First of all, you have the opportunity to hear what happens in the room from any distance, because the transmission of the intelligence intercepted takes place via a phone call, and the bug works just like a regular cell phone that calls you on a preset number, when its automatic activation sensor detects a sound.

The second benefit is the unlimited duration of the wiretapping operation, because the bug is powered through the same electrical outlet where it is hidden .

In short, a complete surveillance package, continuously operating and almost impossible to spot! For more information on the GSM bugs you can visit the Endoacustica website.

Metaflex, the invisibility cloak really exists

novembre 4, 2010 Technology No Commenti

Since ancient times, the most desired piece of clothing for men and women alike has always been an item … that does not exist: the invisibility cloak.
Metaphor for unattainable wishes, such an impossible cloth was the prerogative of characters from fantasy stories, and often ended up causing more harm than good to those who used it.

Now, according to a research by scientists at the University of St. Andrews in Scotland, this dream could finally become a reality. In fact, the team of researchers is developing a new metamaterial (that is, an artificial material with properties not available in nature), capable of “bending” electromagnetic waves.

This material, called Metaflex has a “negative refraction index” which allows it to bend not only electromagnetic waves but also rays of visible light, in a way which, at least in theory, would make any object coated with this material invisible to human eyes.

The properties of this material could be used to make ships or submarines invisible to sonar waves, but being able to make it usable with visible light and with its shorter length waves, and on flexible objects such as a piece of clothing, is a very difficult challenge.

The Metaflex addresses this challenge by using meta-atoms that are stacked together. Previously, meta-atoms, which as the name suggests are the ones that make up meta materials, were used on hard and flat surfaces, such as the outer shell of a submarine. Manipulating their structure, it will be possible, according to researchers, to create a flexible metamaterial with which to manipulate the behavior of visible light, creating not only the legendary invisibility cloak, but also super-lenses to be used for artificial eyes, certainly less fascinating but more useful for visually impaired people.

Marital infidelity, the Net is the new frontier

novembre 3, 2010 Technology No Commenti

According to statistics, cases of marital infidelity worldwide are on the rise. In fact, according to a research from the Italian Association of Matrimonial Lawyers, at least 55% of husbands and 45% of wives have cheated on their spouse at least once.

A large chunk of this increase is certainly due to the widespread presence of social networks, which allow people to start more easily a correspondence with people of the opposite sex, thus creating the conditions for an extramarital fling.
Thanks to Facebook, a bored or unsatisfied husband or wife can find an old boyfriend or girlfriend from school days, and the correspondence can eventually lead to meeting for a coffee or perhaps something else.

The possibilities offered by the virtual world allow even the shyest ones to overcome insecurities due to a not always perfect physical appearance, leaving aside their fears, and freely express their hidden or repressed true personality. From this to a secret meeting, the road is not too long, and in no time the statistics of marital infidelity could have one more case.

In Italy, for example, there is a specialized website for finding short-term partners (no, we are not giving you the address…), a perfect example of “technologically assisted adultery” where everyone can find a casual partner compatible with their tastes and privacy needs. This site already has over 90,000 members, most of which are of course men, especially over forty years of age.

On the one hand, however, if technology is a great help for those who are in search of adventure, on the other side it can also become their worst enemy; in fact, many cases of adultery are discovered by wives or husbands, who notice a suspicious or stealthy attitude in their loved one, and spy a mobile phone in search of compromising signs such as a message or phone call.

A good half of infidelity cases, in fact, are exposed by snooping on cell phones, while the remaining half is split more or less equally between hiring a private detective, checking spouses’ email correspondence or taking an active technological stance, by using a spy phone, which lets you listen to its user’s calls, in real time and invisibly, and also gives you access to all messages, incoming and outgoing, while the user is completely unaware.

In short, while technology provides unexpected opportunities for cheating spouses, on the other, the cheated husband or wife can use it take a nice revenge …

Car, plane, helicopter and speedboat, all in one

novembre 3, 2010 Technology No Commenti

We have seen more than once cars that, by pressing a button or so, can turn into small planes, two-seat helicopters or small speedboats, but we have not yet seen one that could be able to transform into all three.

The idea was developed by British designer Philip Pauley, who has given birth to his Halo Intersceptor, a concept hybrid vehicle which, in normal conditions, is a normal (albeit sporty) car.
The interior of this car is essentially unchanged in each of the four configurations. What changes are the different accessories that must be strapped on the car depending on whether you want to use this vehicle to fly like a plane or a helicopter, or ride the waves on a boat.

The car itself is already very powerful, as it would be able to reach, in its designer’s intentions, a top speed of 500 kilometers per hour.
By strapping on it a couple of triangular wings and two Pratt & Whitney engines, Halo would become an aircraft capable of reaching a top speed of Mach 2, flying at over 20 thousand meters of altitude.

As a helicopter, it would have a range of 450 nautical miles and a top speed of 185 knots at an altitude of about 4500 meters.
Finally, for those who want to use it in water, Halo would be able to turn into a speedboat capable of a range of 1200 nautical miles and a cruising speed of 38 knots, with a maximum of around 60 knots.

This high-profile performance in each of the four configurations, suggests that Halo Intersceptor would probably never see the light, and if it should ever hit the markets, it is certainly not a vehicle that could be affordable for those who would love turn their cars into helicopters to escape the city traffic on a Monday morning.

Bugs power supply, for long lasting wiretaps

novembre 2, 2010 Technology No Commenti

Although the Berlusconi government in Italy, while stumbling from a sex scandal to the next, is trying to put a cap on wiretapping operations, by imposing a time limit, fortunately this investigative tool is still in use without too many restrictions that would only do a favor to criminals and crooks.

When a judge orders a wiretapping operation, either environmental or over the phone, what is known is when it will start, but not when it will end. This poses a problem too many times underestimated, when it comes to the duration of the interception, that is, the problem of how to ensure that bugs are correctly functioning.

Generally, eavesdropping devices are battery powered and communicate either by radio, or over the telephone network if the bug in use is a GSM bug with a SIM card just like the one of an ordinary mobile phone. Transmission via telephone is very demanding in terms of battery power.
Therefore, where possible it is recommended to use a bug has a power supply, to be connected directly to the mains from the electricity network, from which with very limited power consumption it will be possible to provide juice for your bugs, continuously for months and months.

Thanks to its tiny size, concealing it is not a problem, as it can be hidden inside an electrical box or a switch. In this way, hidden microphones connected to the power supply will ensure a continuous listening, perfect for long-term surveillance operations, during which it is important to ensure continuous coverage of the environment to control.

For full details on listening devices, bugs power supply and a wide range of equipment for room and phone eavesdropping, we suggest that you visit the Endoacustica website and contact our experts for advice tailored on your needs.

Manned-Unmanned demo for U.S. Army UAV

novembre 2, 2010 Technology No Commenti

According to officials from the Department of Defense of the United States, the U.S. military is preparing a large-scale demonstration to be held in September next year in the Utah desert.

The object of this demo, dubbed MUSIC (Manned Unmanned Systems Integration Concept) will be the showcasing of possibilities of interaction between unmanned aerial vehicles (UAVs) and air and ground systems controlled by human personnel.

This demonstration is aimed at analyzing in detail the progress being made in cooperation and interaction between automated technologies and those that, in order to work perfectly, still need a human mind and eyes to control them and manage their operation.

For example, a demonstrations will be made of how the pilot of an Apache helicopter will be able to control, from the cockpit of his chopper, also an unmanned drone that flies nearby, to display on its screen also the images picked up by the UAV’s video systems, and even to launch any weapons that are mounted on the unmanned vehicle.

In this way, the pilot of a helicopter or small plane will actually be able to control two vehicles, with the UAV acting as a support, not only for aerial reconnaissance, but also in real attack missions.
The demonstrations will involve different types of helicopters, such as Shadow, Raven, Hunter, Grey Eagle, and of course the Apache AH-64 Block III.

While the Apache takes control of the drone next to it, other helicopters in the squadron will be able to view real-time feeds captured by the on-board systems of both vehicles, with an effective information exchange, coordinated by the ground control center, which provides a significant advantage over an enemy.

Laser microphones, and long distance listening becomes reality

novembre 1, 2010 Technology No Commenti


When a group of dangerous criminals, or a mafia “cupola”, meets in secret to make decisions on their illegal business, they usually take a number of precautions to ensure that the police can not catch them.

In such situations, any operation of wiretapping of phone lines or planting of bugs is almost impossible, unless the lives of agents are put in grave danger, also risking the failure of the entire chase.

Therefore, to gather intelligence, the police may use tools to listen to conversations from a distance, in order to gather the information in the safest possible way. For example, this is the case with laser microphones, which give their users the opportunity to capture the conversations that take place inside a closed room, thanks to the use of a laser beam.

The laser, appropriately pointed at the window glass, in fact, is able to read the small vibrations of the glass caused by sounds, noises and voices inside the room. By pointing the beam on the glass at the correct angle, and retrieving the reflected beam with a receiver, you can read these vibrations, and turn them into sound and voice, enabling you to successfully carry out a remote listening operation without running any risk.

In fact, the laser microphone is able to secretly pick up conversations at a maximum distance of approximately a mile, allowing the monitoring agents to work without excessive stress, and to quickly take shelter in case something goes wrong.

Not only for law enforcement, but also for private detectives who are following a case of industrial espionage or marital infidelity, the laser microphones can prove very useful; if you wish to learn more about them, you can visit the Endoacustica website.
