November 2, 1936 - the beginning of television
By Darren Quick
15:22 November 19, 2009 PST
Although computers and the Internet have eaten away at the dominance of television, it remains the most popular form of entertainment and source of information in the world. And with the line between TV and computers blurring with the advent of Home Theater PCs (HTPCs) and devices like Apple TV it’s likely that television in one form or another will retain its crown for some time to come. Television is no longer limited to a big box sitting in the corner of the living room. It can be accessed on sexy, slim panels hung on a wall or on mobile phones while sitting on a train. In fact television is so pervasive today it can be hard to imagine life before it existed – but there was such a time, and it wasn’t even that long ago. Read More
A cheap way to increase capacity and improve download speeds of strained broadband networks

A new technology that applies the same principles used by ADSL to improve the capacity of data transfer over copper and wireless broadband could potentially increase the data capacity of optical fiber cables tenfold. It’s creators say the technology, known as optical Orthogonal Frequency-Division Multiplexing (oOFDM), offers an inexpensive way drastically boost the capacity of increasingly strained broadband networks and improve download times around the world.

MIT's one-way road for microwave light makes efficient lightwave circuits closer
19:13 October 13, 2009 PDT
Light normally bounces off obstacles in its way, and the part of the beam that is reflected back and captured by our eyes contributes to our perception of the world around us. However, every reflection dissipates a small part of the beam's energy, and can eventually weaken it significantly. A team of MIT researchers have developed an innovative waveguide that allows microwave light to travel one way only and without reflections, paving the way to much more efficient lightwave circuits and connections.

Speedy communication takes a quantum leap towards reality
18:15 October 7, 2009 PDT
Quantum computing is expected to revolutionize electronics over the course of the next few decades, but a number of outstanding issues still remain. One such problem is that "qubits," the basic building blocks of quantum information, are very fragile and can be easily destroyed when sent on a fiber optics cable, due to the surrounding noise. Working on this issue, a team from Stockholm's KHT University, led by Magnus Rådmark, has developed a new method for combining six photons to obtain a robust qubit that is resistant to noise and is, therefore, able to travel long distances without interference.

'Time telescope' speeds up optical transmission by 27 times
22:17 October 4, 2009 PDT
Most of today's telecommunication data is encoded at a speed of 10 Gbit/s, but researchers are constantly looking for new ways to push this limit even further. A group of researchers at Cornell University have recently come up with the "time telescope," a sophisticated system that can speed up optical communication by 27 times to an outstanding 270 Gbits/s by squeezing more information into a single flash of light and that, unlike previous solutions, does so in an energy-efficient manner.

Mechanical bolt-on KERS hybrid for buses offers 30% fuel saving
By Gizmag Team
03:05 October 3, 2009 PDT
It seems that the lessons learned in developing a mechanical KERS system for F1 may yet hold the key to a low-cost, high-efficiency hybrid system particularly suited for the stop-start patterns of buses, which are quite similar to the distances between capturing and delivering energy of those of a race car. Torotrak will deliver a paper at the SAE Commercial Vehicle Congress in Illinois next week showing how flywheel KERS for buses can offer more than 30 percent fuel saving over the London bus test cycle, yet package around an existing transmission.

Mazda’s eco-friendly next-generation engines to debut at Tokyo Motor Show
By Darren Quick
20:57 September 30, 2009 PDT
Mazda's “Technologies for Tomorrow” display at the upcoming Tokyo Motor show will see the premiere of its next-generation direct injection gasoline Mazda SKY-G engine and Mazda SKY-D clean diesel engine, which offer improved eco-friendliness and torque thanks to optimized combustion efficiency. Mazda will also reveal the first next-generation automatic transmission, the Mazda SKY-Drive, which offers first-rate fuel economy and a direct driving performance feel. As part of Mazda’s SKY concept, the new engines and transmission are designed to help Mazda achieve its goal of improving the average fuel economy of Mazda vehicles 30 percent by 2015, compared to 2008 levels, without sacrificing performance.

Torotrak’s new generation transmission is good gear
By Darren Quick
00:30 September 3, 2009 PDT
Most of the efforts to produce more environmentally-friendly cars in recent years have focused on alternative fuels and more efficient engines. UK-based engineering company, Torotrak, has instead decided to turn its expertise to another vehicle component with the development of a new generation transmission that it claims can not only slash CO2 emissions and improve fuel efficiency, but also boost performance.

Nissan's next generation CVT claims world's highest transmission ratio
By Jeff Salton
18:14 July 30, 2009 PDT
Nissan and its transmission supplier Jatco have developed a next generation CVT (continuously variable transmission) that promises better fuel economy and performance in a compact and lightweight package. The new CVT combines conventional CVT belt operation with an auxiliary gearbox and has a significantly increased gear ratio range – roughly 20 percent higher than other CVTs and among the world's highest for production vehicles according to Nissan.

USB 3.0 explained: How the next-generation USB will reach speeds of 4.8 Gbit/s
23:53 June 9, 2009 PDT
Scheduled to hit the consumer market in 2010, USB 3.0 — also known as SuperSpeed USB — will deliver a tenfold improvement in data transfer rates while retaining backward compatibility with previous versions and adding new features that will make this communication standard all the more essential to the average consumer. But, speed aside, what changes is the next version of this popular standard going to bring? Read More
New multi-speed Electric Vehicle transmission improves EV performance and range
By Mike Hanlon
16:08 May 12, 2009 PDT
The Electric Vehicle Symposium (EVS) opens in Norway today and will see the official unveiling of a novel multi-speed electric vehicle gearbox by transmission specialist Vocis. Simulations show that a two-speed configuration could reduce the battery energy consumed by 5-10 percent over the industry-standard New European Drive Cycle, without any significant increase in overall cost or packaging volume, as well as extending battery life and providing the potential to substantially downsize the powertrain and battery pack.
