Researchers at the Technical University of Denmark (DTU), the same people who in 2009 had passed the barrier of the terabit have now attained the stratospheric rate of 43 Tbps with a single optical fiber using a single laser transmitter. If there was such a connection it would be likely to transmit 1 TB of data in less than 0.20 seconds or 1 GB in less than 0.2 milliseconds! The previous record (26 Tbps) of 2011 belonged to the Karlsruhe Institute of Technology.
In the past, several demonstrations have been carried out with fiber optic networks that arrive at even higher speeds, even thousands of terabits per second, but they all use multiple lasers of multiple fibers. It is so of laboratory experiments that probably will never arrive on the market. The fiber optic links commercial (for example, the entire backbone of the Internet) are in fact based on the individual fibers and individual laser. That’s why the university Danish discovery is very significant for the future of communications.
A recent study has highlighted the poor energy efficiency of existing connected devices. With the expansion of so-called internet of things, the number of smart devices will increase exponentially in the coming years and with them the need for electricity. PsiKick a startup of Virginia, however, has designed a wireless sensor that does not require external power, thanks integration of chip “sub-threshold”.
The transistor is a switch that is turned on, applying a voltage higher than the threshold, and OFF if the value is less. In fact, the transistor runs a small leakage current, even in the off state, which can be exploited to perform certain tasks. This allows reducing the waste of current associated with the on-state. The chip designed by the United States operates on “sub-threshold”, consuming 0.1% of the energy required by the chip currently on the market.

There are only a few minutes before checking in for your flight, or closes before your train departs, but you have to use valuable time looking for a space in the parking lot of the airport or the train station. Imagine leaving your vehicle at the main entrance and let the car do the rest by itself.
With these words, the European Union has V-Charge, a research project funded with 5.6 million Euros that will allow in the future simplifying the integration between private and public transport, through a system of parking and automatic charging for electric cars. The consortium is composed of the same name by Bosch, Volkswagen and four universities, including the one in Parma.
The driver can leave their car in face of the parking lot and use a mobile app to send the command to the vehicle parking. Latter will connect to the server to download the parking map and look for a free spot in an autonomous way. Eventually, the car may also look for a charging station. With the same app, the user will call the vehicle that will arrive at the entrance of the airport, as you can see in the following video. Continue reading

A GPS module built into the soles of shoes not to monitor physical activity but in order to make the geo location of the wearer. Is this in a nutshell the usefulness of a device such as GPS Smart Soles? In that context may be useful a manufactured goods of this type? For example those that deals with people suffering from senile dementia which are likely to get lost easily or to know at any time where there are children.
The operation is quickly explained inside the base is a small modem with battery and SIM card to communicate with mobile networks, which is required in order to transmit information about geographic coordinates every five or ten minutes (the time interval can be changed by using a special app). Autonomy declared is concerning five days and charging is done wirelessly.
In addition to having reduced autonomy, the battery current must be produced respecting certain constraints. Although they are available in various sizes, still maintain their rigidity, so are not suitable for powering any device. California startup imprint energy has developed a rechargeable zinc and flexible polymer that can be printed and used in wearable medical devices, smart labels and environmental sensors.
The company’s goal is to create batteries safer for on-body applications, while their small size will allow for the use in food products can not be with the bulky lithium-ion battery. Imprint Energy batteries are based on a technology that the company’s co-founder Christine I developed at the University of California at Berkeley, where he worked with a Japanese researcher to create microscopic batteries using a 3D printer.
The built-in batteries in notebook computers, tablets and smartphones contain lithium, a highly reactive material that requires an external protection. This, however, adds weight and increases the size. The zinc instead is more stable, but the water-based electrolyte in the batteries causes the formation of dendrites, branched structures that can grow between the electrodes, causing a short circuit. I achieved a solid polymer electrolyte that avoids this problem, while offering greater stability and a superior ability to recharge. Continue reading
The so-called self-driving car may represent a safety hazard. Not for drivers that circulate on the streets but police forces engaged in pursuits of a fugitive. According to a FBI report autonomous rail cars can become lethal weapons allowing criminals to perform actions that require the use of both hands or to remove your eyes from the road. However, these vehicles will make monitoring easier.
The driverless car integrate different devices (laser, radar, GPS, video cameras and various sensors) that reduce the risk of accidents, since they allow you to preset destination avoiding obstacles and respecting the highway code. But the FBI believes that these technologies can be leveraged to perform dangerous actions. Theoretically, you could disable the security features to ignore speed limits and traffic lights. Terrorists could remotely control a vehicle stuffed with explosives and turn it into a self-driving bomb.
Android wear is a platform designed especially for smartwatch new age group. Even Google has been interested in the growing world of wearable devices after reaching the leadership in the market of smartphones and tablets the group also tries to conquer smart watches and bracelets giving to their partner companies an operating system capable of providing a user experience immediate and at hand rather than the wrist for each type of customer. The debut of Android wear will be July 7 at the similar time the production of the first watches of Samsung and LG.
Wear Android: notifications on your wrist
Wear Android is a platform based mainly on voice commands and be able to show, through a simple tabbed interface , a wealth of information in real time directly on the user’s wrist. Will be sufficient to match the smartwatch or any other types of wearables that in the future could arrive in stores through the system in any smartphone based on Android 4.3 Jelly Bean or higher to get to the various notifications.
Specifically Android Wear shows information and suggestions based on interests of the user, at the right time. The app will provide updates from social networks, chats with your contacts, notifications on messages received, on orders from the websites of e-commerce, news, and display shared photos information on a departing flight, maps, and Google Maps other.

ASIMO (Advanced Step in Innovative Mobility) humanoid robot is probably the most famous, as announced by Honda back in 2000. Since then, the Japanese company has made a number of improvements both in appearance and functionality. Honda has today announced the 2014 version of the robot that becomes an autonomous machine as it can make decisions without human intervention by analyzing the surrounding environment such as movements of people.
Japanese engineers have worked mainly on artificial intelligence ASIMO trying to imitate sight hearing and touch of the human being. ASIMO can now modify its actions based on the intentions of those with whom it interacts. The robot for example is able to predict the course of a person who meets in its path moving laterally to avoid the collision. This is also probable thanks to the ability to quickly change your posture, without losing balance.
Researchers at the Georgia Institute of Technology have developed a humanoid robot that can help in the rehabilitation of children with disabilities. The project initiated by the university the U.S. involves the use of a tablet Android and the hit game Angry Birds. The children interact with the robot, under the supervision of an adult. The programming of the robot, carried out by a doctor, is based on the specific needs of the young patient.
While the child plays on the tablet, throwing birds against the pigs’ buildings, the robot observes the initial and final position of the fingers on the screen, the movement of objects and the score, recording “snapshots” in his memory. When it is his turn, then the robot mimics the movements of the child, trying to get the same positive result. If no construction is destroyed he shakes his head in disappointment.

At the end of 2013 Amazon has surprised a bit all announcing the project first air. It is essentially a program for the use of drones to manage the delivery of the goods purchased by users on its e-commerce store. This would guarantee customers the opportunity to receive the products in a short time it is even spoken of 30 minutes directly on the landing of the house.
Of course, before you can come up with something even remotely comparable to what is shown in the concept video streaming that follow are lengthy testing and specific permissions. It is still flying devices that move therefore a potential source of danger to public safety if not controlled properly.
