Quantum / AvMap's QTM 1000 Nav handheld touts DVB-H and GPS
Quantum and AvMap are teaming up to produce what they dub the "world's first" DVB-H capable Pocket TV with SAT NAV functionality, and while we've seen a touch of DVB-H in handheld devices before, it's good to see yet another creation joining the do-it-all fray. Announced at 3GSM, the Linux-based QTM 1000 Nav boasts a 4.3-inch WQVGA widescreen display, 400:1 contrast ratio, 80-degree viewing angle, DVR functionality, 128MB of Flash memory, 64MB of onboard RAM, an SD card slot, dual stereo speakers, a four-hour rechargeable battery, SiRF Star III receiver, Tele Atlas maps, and USB 2.0 connectivity. Aside from playing back DVB-H signals at 25 frames-per-second, it also allows viewing / purchasing of Pay TV channels, and it plays nice with H.264, MPEG4, AAC, MP3, JPEG / GIF / PNG, M4V, and AVI files when not tuning in to a broadcast. Unfortunately, there weren't any details regarding price or future availability, but those kicking around in Europe should give this one some serious consideration if you're looking to consolidate.
World's first "commercial" quantum computer solves Sudoku
As expected, Canada's D-Wave Systems has announced "the world's first commercially viable quantum computer," and they seem to be pretty stoked about it. The achievement is notable, since they've managed to build a whole 16 qubit computer that actually does some simple computations, even if it's far less powerful than even the most basic of home computers. Qubits are quantum bits that can be in an "on," "off" or "both" state due to fuzzy physics at the atomic level, and up until now the best anyone had done was get three qubits together for computing. This 16-bit version can solve Sudoku, create a complicated seating plan and search for molecular structures, but quantum computers will need to be in the range of thousands of qubits to be able to solve puzzles -- such as encryption -- that current computers cannot. D-Wave is planning to have a 1,000 qubit version ready by the end of next year, but scientists in the field are skeptical. The adiabatic method used by D-Wave, which cools electronic circuits into a superconducting state, with the resulting qubits being slowly varied in a magnetic field, might not be able to keep its speed when on that large of a scale. "It probably won't work but it's not quixotic," says Seth Lloyd of MIT. "If it works then they can solve really hard problems and they'll be very much in demand," he says. But it's a long shot: "It's certainly not the kind of company I'd invest my money in." To raise awareness, D-Wave will be opening the computer up to computational problems over the internet after the results of the project are peer-reviewed. More pics after the break.[Via Digg]
Atomic "transistor" proposed using quantum cloud material
Intel might be oh-so-smug about its fancy new insulators and 45nm process, but doesn't have nothing on these upcoming atomic transistor dealios -- other than that whole "shipping" thing, of course. Scientists working at the Worcester Polytechnic Institute in Massachusetts and compadres at the University of Colorado Boulder have proposed implementing a "Bose-Einstein condensate" to pull this off -- a super-cold gas cloud of atoms all in the same quantum state -- which is manipulated with three adjacent chambers that are created by trapping atoms with magnets or laz0rs. By swapping atoms between the two side chambers, and controlling that action with the center chamber, a behavior is created similar to that of an electronic field-effect transistor. Which is apparently a good thing. So yeah, the tech definitely flies over our heads, but if this works it sounds like it's a pretty big breakthrough in building atomic "circuits" some day by connecting basic atom elements and should hopefully keep Moore's law alive and well a few decades down the road.[Thanks, Jeremy]
Inventor crafts GPS-equipped shoes, includes a panic button
We've seen some fairly interesting means of keeping track of your mischievous kids (or pets), but Sayo Isaac Daniel's latest invention takes top honors as the ultimate paranoid parent's must-have gizmo. Aside from the obvious tracking uses, Daniel's GPS footwear is actually intended to beam out a distress signal to a pre-selected recipient if the wearer hits a certain panic button. The GPS-equipped kicks would present the location of the violated victim to whoever is deemed that person's hero, and would hopefully give the rescuer enough time to arrive and lay down the law. Also, the patent explains an "alarm toe switch" that would be inserted within the shoe in order to give customers the ability to sound their alarm (intentionally or otherwise) without making any sudden movements. Reportedly, a company dubbed Quantum Satellite Technology plans to start selling the shoes "in March for around $350 per pair," but the GPS signal emanating from your soles won't do you much good if your kidnapper ditches your footwear before tossing you in the trunk.[Via The Raw Feed]
