Nokia had a lot of innovation to show at the Nokia World in London. We’ve already seen the Lumia mobile phones and the flexible smartphone prototype, and now this smudge-free touchscreen. For all of us touchscreen phone users, a screen like this would be a gift from the gadget gods.
As is the norm, alarm clockstake pride in being loud and scary while waking us up. They may fulfill the purpose, but they don’t do it the best way possible. This new alarm clock, devised by a team at the Jerusalem College in India, might be able to do its job in a lot more efficient manner. Basically, our sleep can be divided into a number of stages, with stages 1 and 2 being close to awake stages, and stages 3 and 4 being the stages of a deep slumber, followed by REM.
For a while now, we have been seeing concepts that use projection technology to virtually turn any surface into a touchscreen. Desirable as these systems are, they have always been something out of reach, not quite ready for production. Things for such systems now seem to be looking up with the entry of Microsoft into the arena.
As observers, all we see when a falling droplet hits water, is a slight disturbance at the point of impact. The reality is a bit more complex with more physics involved. It’s fluid dynamics to the rescue in explaining situations like these. As the slow moving droplet hits the water surface, a tiny layer of air beneath the droplet often prevents it from simply being absorbed into the pool.
Researchers at Japan’s Miyazaki University have devised a system that will make life slightly easier for people paralyzed from the neck down, or have lost muscular strength in their body. The team led by Professor Tamura devised the system where the wheelchair can be turned towards the left or right by simple blinking of the eyes, while clenching teeth can both set it into motion or bring it to a stop. A commercial version of the wheelchair is expected to be available next year.
For a long time now, the world has been dreaming of compact nuclear generators that could be used to power homes or vehicles. To be true, realizing that dream is still a far way off but developments are underway that might pave way for the future. Massachusetts-based R&D firm, Laser Power Systems (LPS) is working on a thorium based laser that would power a turbine or electric generator system. Thorium as an element is mildly radioactive, and about as abundant in nature as lead.
Hurricane Irene is nearly done with its destructive ways and has already been downgraded to a Category 1 Hurricane. NASA has released a set of images showing the hurricane from space. The images were taken by the NOAA GOES-13 satellite.
Long story short, the report basically says that most ISPs do not provide the speed they advertised for. FCC worked with Georgia Tech professor Nick Feamster to find out the “real world” speeds at which the ISPs are working. The data was compiled by a company called SamKnows, who worked with 78,000 internet users, providing 9000 of them with routers configured to provide accurate results. The results say that at an average, ISPs provide download speeds that are 80-90% of their advertised values. Of course, some perform better than the others, and many would likely be able to beat a carrier pigeon, but the fact remains that the internet speed provided to the consumer is lower than what was advertised.
We may all be satisfied with today’s conventional polygon-based graphics but there is always room for improvement. You see, the number of polygon shapes that can be used, and the resulting detail is limited by computing power, now this new system from the company Euclideon says that graphics can be created by 3D virtual atoms, much like atoms in the real world. This point cloud data would apparently result into a lot more detail coming from graphics, but without using the substantial amount of resources the current polygon-based technology requires.
