HIOD One is a Bluetooth communications system designed for cyclists

Whether you have the wind whistling in your ears on the highway, or the sound of scrunching tires coming from beneath you on a singletrack trail, it can often be difficult to hear what other cyclists are saying. While most of us are just content to yell “WHAT?”, Swedish wireless tech company Free2Move has what it thinks is a better idea – it’s HIOD One, a Bluetooth communications system designed specifically for cyclists.  Read More

Since the dawn of the space age, NASA has been relying on radio communications technology to send and receive data to and from spacecraft. Although it has developed higher data-rate radio frequency systems, data-compression, and other techniques to boost the amount of data that its current RF systems can handle, they can't keep pace with the projected data needs of advanced instruments and further human exploration. To break this bottleneck, NASA is turning to optical communications technology that would use lasers to increase data rates over existing systems by anywhere from 10 to 100 times.  Read More

The concept demonstrator system developed by BAE Systems incorporating Body Wearable Anten...

Reliable communications are almost as critical to the modern soldier as their weapons and ammunition. Conventional whip-antennas are not only cumbersome and conspicuous, but they don't always provide a reliable link between a soldier laying on the ground and one standing up. Meanwhile, the short antenna of a portable radio can mean the signal is masked by the user's body. To provide more reliable, continuous 360-degree radio coverage, BAE Systems has developed a series of Body Wearable Antennas (BWAs) that, like the experimental antenna system recently developed at Ohio State University, sees the antennas weaved into the fibers of a uniform.  Read More

Search giant Google has teamed up with the Bletchley Park Trust to kick start a fundraising effort to rebuild the records center known as Block C. A Google-supported garden party was held within the grounds of the famous WW2 decoding center last week to start off the restoration fund, which aims to transform the now derelict building into a visitor and learning center.  Read More

Lockheed Martin's HALE-D is launched

With the use of airships for passenger transport decreasing in the early 20th century as their capabilities were eclipsed by those of airplanes – coupled with a number of disasters – they were largely resigned to serving as floating billboards or as camera platforms for covering sporting events. But the ability to hover in one place for an extended period of time also makes them ideal for intelligence, surveillance and reconnaissance purposes, which is why Lockheed Martin has been developing its High Altitude Airship (HAA). The company yesterday launched the first-of-its-kind High Altitude Long Endurance-Demonstrator (HALE-D) to test a number of key technologies critical to development of unmanned airships.  Read More

Even though firefighting is one of the most dangerous jobs in the world, firefighters still communicate using analog radio signals, that can be blocked by concrete walls. This means that, upon venturing into a burning building, a firefighter might have no way of letting their commander know their present location – a situation that could prove deadly, if they ended up trapped or injured. In order to address the situation, the U.S. Department of Homeland Security’s Science and Technology Directorate has created a new three-part system that lets fire crews keep track of the location and well-being of every member of their team, all the time.  Read More

The HomePlug GP standard allows EVs to communicate over the Internet via their charging po...

Electric vehicles (EVs) may be set to charge smarter following an announcement by the HomePlug Powerline Alliance at Computex 2011. The body responsible for the compliance and certification of the HomePlug powerline communications standard said that German automakers Audi, BMW, Daimler, Porsche and Volkswagen have thrown their support behind the HomePlug GP (Green PHY) standard that will allow electric vehicles to be connected via existing home electrical wiring to a home network or send and receive data over the internet via the vehicles' charging ports. This will not only allow EVs to intelligently take advantage of lower cost, off-peak electricity, but will also allow for remote checks of the vehicle's systems and battery condition.  Read More

Fraunhofer's Marc Gayer, Manfred Lutzky and Markus Schnell (L to R), developed AAC-ELD to ...

Engineers from one of the main players responsible for the development of the MP3 codec, the Fraunhofer Institute for Integrated Circuits IIS, have taken a similar approach in an effort to provide telephone calls and video conferences with sound quality approaching that of direct communication, while at the same time cutting delay times that often sees both speakers talking over each other. Their solution is a new audio coding technology called Enhanced Low Delay Advanced Audio Coding – or AAC-ELD – that they claim results in long-distance communications that appear almost as if the participants are sitting across from each other.  Read More

Black Diamond's MTS: lightweight, ultra-rugged wearable computing and communications kit

Military computer manufacturer Black Diamond Advanced Technology has released its ultra-rugged wearable PC and communications kit as a commercial-off-the-shelf (COTS) system. Adaptable to a range of specialist missions, the Modular Tactical System (MTS) system is - as the name suggests - not just a pack containing a computer. Components are split-up are and integrated into different parts of the soldier's uniform and equipment so that mobility isn't compromised, and it's designed to make the transition from computer operation to direct combat engagement in seconds.  Read More

Professor Jurg Leuthold led an experiment that achieved a data transmission rate of 26 ter...

With video content consuming ever more bandwidth, the need for faster data transmission rates has never been greater. Now a team of scientists at Germany's Karlsruhe Institute of Technology (KIT) are claiming a world record in data transmission with the successful encoding of data at a rate of 26 terabits per second on a single laser beam and transmitting it over a distance of 50 km (31 miles). The scientists claim this is the largest data volume ever transported on a laser beam and enables the transmission of 700 DVD's worth of content in just one second.  Read More
