Tacit sonar gauntlet gives the blind ultrasonic eyes (video)
Sure, your Arduino project can make a stuffed monkey dance, but is it really doing anything for the greater benefit of mankind? Okay, maybe -- but not to the same degree as Grathio Labs' Tacit glove, an Arduino powered sonar device that can help the vision impaired navigate foreign environments. This wrist-mounted gauntlet is comprised of an Arduino microcontroller, a few ultrasonic sensors, and a pair of servomotors to apply variable pressure to the user's wrist to indicate their distance from an object or obstacle. Best of all, the gizmo's circuit and software are registered under Creative Commons, which means you're free to snag the plans from the source link below, and build your own. Go on, build one. Sure, it's a lot of work, but would you rather rock a wrist-mounted sonar gun, or don an ear-tugging bicycle helmet? Your choice.
Lingodroid robots develop their own language, quietly begin plotting against mankind
It's one thing for a robot to learn English, Japanese, or any other language that we humans have already mastered. It's quite another for a pair of bots to develop their own, entirely new lexicon, as these two apparently have. Created by Ruth Schulz and her team of researchers at the University of Queensland and Queensland University of Technology, each of these so-called Lingodroids constructed their special language after navigating their way through a labyrinthine space. As they wove around the maze, the Lingobots created spatial maps of their surroundings, with the help of on-board cameras, laser range finders and sonar equipment that helped them avoid walls. They also created words for each mapped location, using a database of syllables. With the mapping complete, the robots would reconvene and communicate their findings to each other, using mounted microphones and speakers. One bot, for example, would spit out a word it had created for the center of the maze ("jaya"), sending both of them off on a "race" to find that spot. If they ended up meeting at the center of the room, they would agree to call it "jaya." From there, they could tell each other about the area they'd just come from, thereby spawning new words for direction and distance, as well. Schulz is now looking to teach her bots how to express more complex ideas, though her work is likely to hit a roadblock once these two develop a phrase for "armed revolt."
V-Studio 100: not a piece of cake but a great piece of hardware
Most aspiring musicians, at least those of us who are computer nerds, have spent time recording their music to distribute it digitally ... to Grandma. Most of us pass GarageBand with flying colors, graduate from Logic Express and eventually get a masters in Logic Pro. I'm admittedly in the learning stages of Logic Pro. I've graduated from my analog mixer and have just begun to learn the real world of DAWs (Digital Audio Workstations). Please keep in mind that I'm admittedly not a sound engineer, just a musician who likes to dabble with audio recording. Recently, we were contacted by the awesome folks at Cakewalk who asked us if we'd like to review the V-Studio 100. I jumped at the chance to test it out and was pleasantly surprised at how versatile it really was. For the last two weeks, I've learned the hardware and software included in this package that helps you sound good: the end goal of any musician. I'll just do a brief overview of what's included because there's a lot there and the conclusion is that it's a winner. It's a lot to learn, especially if you're not familiar with the software or DAW controllers for that matter, but it's a huge step up from my analog mixer.

Found Footage: The iPhone sonic ruler
Have you ever had a device that you wanted to make just a little bit more sonic? Have you ever been up late, measuring rooms and thought: "Could I approach this task with an iPhone? Sonically?" Fortunately for you, the good people at Laan Consulting have already thought of this. They've anticipated this eventuality and are now shipping the iPhone Sonar Ruler [iTunes link] for just a buck on the iTunes Store. Yes, these good folk have imbued the iPhone with sonic goodness. As the video on the next page shows, the application sends short pulses and measures their return delay. Sure, you could go out to Office Depot and spend twenty bucks getting a far more reliable, dedicated unit but isn't it more fun to help support iPhone devs while really pushing the device beyond its design intent? And don't forget: Bananas are good. They are excellent sources of potassium. Thanks to Neekers
Video: simulated 'quiet zone' cloaking hides an object in 2-D
You don't have to be able to pick a Romulan out of a crowd of Vulcans to be intrigued by the idea of cloaking, and indeed many non-trekkers have tried to hide things in plain sight using electromagnetism, acoustic superlenses, or light-bending materials. The latest attempt relies on devices that emit cancelling waves of the sort anyone who's ever seen a Bose commercial should quite familiar with, combining to negate any external, incoming waves. What's different here is that they also recombine on the other side of the object being cloaked, as shown in the video below, meaning that incoming surge is then re-generated and continues on undisturbed -- potentially even reflecting back through the object again should it hit something on the far side. It's part of research at the University of Utah and, for now, only works in a theoretical two-dimensional world where triangles and squares are ruled by pentagons, hexagons, and priestly polygons. Optical camouflage is sadly not believed to be possible using this technique, but sonar and radar are likely implementations, as well as mechanisms to subvert earthquakes, tsunamis, and maybe even neighboring speed metal fans.
Acoustic superlens could mask ships from sonar... in theory, anyway
Man, the mad scientists are really on a roll of late. First we hear that Li-ion cells are set to magically double in capacity, and now we're learning that a new form of invisibility cloak is totally gearing up for its Target debut. As the seemingly endless quest to bend light in such a way as to create a sheath of invisibility continues, the University of Illinois at Urbana-Champaign's Nicholas Fang has reportedly developed a metamaterial that acts as a type of acoustic superlens. In theory, at least, this approach would rely on phreaking with sound rather than light in order to intensely focus ultrasound waves; by doing so, one could hypothetically "hide ships from sonar." To be fair, this all sounds entirely more believable than hiding massive vessels from human sight, but we're still not taking our skeptic hat off until we see (er, don't see?) a little proof.[Via Slashdot]
Sonar hopes to power social featurephones, we get a demo
As with any trade show, flashy, high-end products have a tendency to steal the lion's share of the spotlight at MWC -- but the fact is, featurephones still outsell traditional smartphones by an order of magnitude. Companies like INQ are betting the farm on the belief that today's ultra-connected generation of Twitter, Myspace, and Facebook users are ultimately going to pick fashionable, cheap, easy-to-use handsets over the complexity of an iPhone, G1, or Omnia. There's something to be said for that -- most people don't know the model of their own phone, after all, and have no interest in learning how to download and install an app, let alone learn an entire mobile operating system. Plus, for the youngest members of this profitable group, there's a lot of price sensitivity -- smartphones are typically out of reach.If startup Sonar has its way, that's where its new platform comes in. The idea was to fundamentally rethink the way average consumers -- you know, the ones who are plugged into three, four, or fourteen social networks and don't know a G1 from a P1i -- use a phone to communicate, and they're ready to show off their efforts for the first time here at MWC. We had an opportunity to sit down with Sonar's founders this week for a tour of the system, and we're pretty stoked about what we saw. Read on.%Gallery-45307%
Sony patents ultrasonic controller [update]
A new patent has surfaced from Sony for a PlayStation 3 controller that is tracked "using hybrid video capture and ultrasonic tracking system." The video capture, according to the patent, will be used to track the horizontal and vertical position (as it would be captured on a two-dimensional image) and the sonar will be used to detect the distance between the controllers, the distance from the controllers to the system and nearby nuclear submarines.What's interesting to note as well is that the diagrams included in the patent show a pair of nunchuk-style devices for two of the the three shown people, perhaps related to recent rumors of a "break apart" PS3 controller. We'll poke Sony for the usual "no comment," "patents get filed all the time, nothing to see here" and "hey look, a hamster!"Update: The official statement: "Sony Computer Entertainment files numerous patents globally for the purpose of protecting our inventions. However, it doesn't mean that every patent we file becomes a commercial product. We do not comment on rumors or speculation or comment on each and every patent we file."[Via GamesIndustry.biz]
DIYer constructs Ultrasonic Batgoggles, doles out instructions
To be exceptionally honest with you, Ultrasonic Batgoggles don't exactly need any pimping from us. What you see above is a homegrown device that enables humans to discover how bats must feel when using echolocation in order to judge how far away certain objects are. The main components are an Arduino microcontroller clone, Devantech ultrasonic sensor and a set of welding goggles -- oh, and a sick poker face to really round things out. Check out the links below to get a gist of the background as well as a step-by-step guide to concocting your own.Read - Ultrasonic Batgoggles project pageRead - Ultrasonic Batgoggles How-to guide
Autonomous glider robot safeguards whale pods
We've all heard the diehards claiming that the whales are the ones we should save, and thanks to an autonomous glider crafted by Webb Research, they're finally getting their wish. Recently, a trial was pursued in which a radio / satellite phone-equipped Slocum Glider was sent up to 200-meters beneath the depths in order to survey, pinpoint, and record location data for various whale pods swimming about. The device then surfaces and "phones home" the recently gathered information, which can then be disseminated out to ensure nearby vessels don't enter whale-packed territories. Jim Theriault of Defense Research and Development Canada, Dartmouth ran the experiment, and noted that this iteration of whale sensing and reporting improved on previous attempts by being uber-stealthy, featuring a remote data reporting system, and boasting a signal processor capable of tracking even the baleen whale's "lower-frequency call." Currently, the torpedo runs on batteries which last a month or so without needing a recharge, but future renditions are planned to scour the waters for "between five months and a year" by utilizing a special recharging gel. Look for these to hit your nearest ocean later this summer, and try not to be too alarmed when it surfaces beside your craft.[Via The Raw Feed]
