AT&T to enable BlackBerry Bridge support before sundown

Source: http://www.engadget.com/2011/07/01/atandt-to-enable-blackberry-bridge-support-before-sundown/

Most tablets function just fine on their own, but RIM's BlackBerry Playbook introduced a unique, yet restrictive interface that limits Bluetooth tethering to a similarly-branded handset. This feature, called BlackBerry Bridge, lets your tablet piggyback on a handset's 3G data connection, also enabling access to productivity apps like email and calendar, which are still otherwise unavailable on the PlayBook. Unfortunately, this option hasn't been made available for AT&T users, but that's about to change, as the feature will be added to App World today. While the Bridge suite is totally gratis, enabling the AT&T 3G data connection requires a monthly tethering plan of $45, which means anyone grandfathered into the unlimited data feature will need to decide if it's worth the jump. Bridge not sounding like your cup of tea? Don't worry -- at least you can take comfort in knowing that the days of pining for native email are numbered.

Scientists develop algorithm to solve Rubik's cubes of any size

Source: http://www.engadget.com/2011/07/01/scientists-develop-algorithm-to-solve-rubiks-cubes-of-any-size/

A computer solving a Rubik's cube? P'shaw. Doing it in 10.69 seconds? Been there, record set. But to crack one of any size? Color us impressed. Erik Demaine of MIT claims to have done just that -- he and his team developed an algorithm that applies to cubes no matter how ambitious their dimensions. Pretty early on, he realized he needed to take a different angle than he would with a standard 3 x 3 x 3 puzzle, which other scientists have tackled by borrowing computers from Google to consider all 43 quintillion possible moves -- a strategy known simply as "brute force." As you can imagine, that's not exactly a viable solution when you're wrestling with an 11 x 11 x 11 cube. So Demaine and his fellow researchers settled on an approach that's actually a riff on one commonly used by Rubik's enthusiasts, who might attempt to move a square into its desired position while leaving the rest of the cube as unchanged as possible. That's a tedious way to go, of course, so instead the team grouped several cubies that all needed to go in the same direction, a tactic that reduced the number of moves by a factor of log n, with n representing the length of any of the cube's sides. Since moving individual cubies into an ideal spot requires a number of moves equal to n², the final algorithm is n²/log n. If we just lost you non-math majors with that formula, rest assured that the scientists expect folks won't be able to apply it directly, per se, though they do say it could help cube-solvers sharpen their strategy. Other that, all you overachievers out there, you're still on your own with that 20 x 20 x 20.

Can't wait to get your hands on Vizio's upcoming budget tablet? Good news, beginning today, you can put your $400 where your mouth is, by pre-ordering the device straight from the company's site, starting at 1:30PM ET. That amount will get you the Gingerbread tablet, along with a 16GB MicroSD card, and a folding folio case. Pre-ordered devices will start shipping on July 18th. Those who snoozed and therefore lost will be able to pick one up in stores that same week.

Update: Let the pre-orders begin!

French pilot sets big speed record in tiny electric airplane (video)

Source: http://www.engadget.com/2011/07/01/french-pilot-sets-big-speed-record-in-tiny-electric-airplane-vi/

It may not be all that fast in the broader world of aircraft speed records, but French pilot Hugues Duval still has a fair bit to boast about with his latest accomplishment. Not only did he actually fly the aircraft pictured above -- which weights just 200 pounds and has a wingspan of 16 feet -- but he manged to hit a top speed of over 175 miles per hour, breaking his own record for the fastest all-electric airplane by about 15MPH. Not surprisingly, the plane itself (powered by two 35 horsepower electric motors and a pair of 1.5 kWh batteries) is better suited for short hops and the odd record attempt than any long-haul flights, as it's not able to fly for much more than 25 minutes at a time even at a more reasonable 65 miles per hour. Video after the break (en Français, of course).

HAL exosuit takes a Cybernic approach to disabled tourism

Source: http://www.engadget.com/2011/07/01/hal-exosuit-takes-a-cybernic-approach-to-disabled-tourism/

Cybernics -- it's not a typo, it's a completely new field that mixes cybernetics, mechatronics, and informatics with an all-human core. Pioneered by Tsukuba Univeristy designer Yoshiyuki Sankai, the Hybrid Assistive Limb (HAL) exosuit originally created to aid Japan's eldery has now found an even nobler mission -- assisting disabled tourists. Through detection of weak muscular bioelectrical impulses in the legs, this RoboCop-like lower body suit boosts its wearer's load-bearing abilities by a whopping 176 pounds. The exoskeleton tech first helped paralyzed Seiji Uchida nearly tackle Switzerland's Breithorn peak in 2006 and is now getting another go at the disabled traveler's bucket list. This time 'round, Uchida hopes his ride atop a HAL-outfitted human will successfully carry him to the top of Normandy's rugged Mont Saint-Michel, paving the way for other similarly handicapped travelers to do the same. Although the robotics in question here is more mech suit than say, dental training real doll, it's still a huge leg up for the nascent research industry that got its kick-start making a wish come true.
