10 Genius Inventions

10 Genius Inventions We're Still Waiting For Sonic Showers, Augmented Reality/Illustrations by Ian Kim Sonic Showers Though much has changed since humankind fled the wilderness for civilized comforts, one thing hasn't: We still clean ourselves with water. Yet traditional showers take time, waste resources and don't necessarily get the job done. Instead, we should take a lesson from doctors who sterilize surgical instruments through techniques such as high-pressure, high-temperature autoclaves, ethylene oxide gas and ultrasonic vibrations. While these methods aren't exactly "people-friendly," a little research may enable modern humans to step out from under the indoor waterfall and give up the last of our caveman-like ways. Augmented Reality Kids' knees and noggins can be protected with padding and helmets -- but how do we safeguard their delicate minds? The answer may lie with Augmented Reality (AR), a technology that combines sights and sounds of the real world with virtual information. AR eyeglasses could detect inappropriate sights and remove them from view, while AR-enabled earbuds would delete ambient cursing. Meanwhile, adults might wear glasses that substitute blessed blank space for roadside billboards, television commercials and the annoying corporate names on most stadiums. Professor Jie Yang of the interACT research center at Carnegie Mellon University recently laid the groundwork for this technology. His prototype digital camera picks out street signs and billboards from a scene and translates their text to another language. Next on his to-do list, we hope: figuring out a way to translate obnoxious on-hold music into songs we actually like. Life Simulator The world is complicated, and big decisions can be hard to make. Instead of trusting your own fallible human intuition, why not plug the variables of your life into a supercomputer and watch your fate unfold by the numbers? Advanced simulation software could generate a slew of parallel lives, each following a different fork in the road: where you live, which person you date or whether you adopt that Great Dane puppy. The U.S. Army already uses tactical simulators to predict the outcome of battles and to fine-tune supply-chain logistics. Now, researchers at the Institute for Creative Technologies at the University of Southern California are working on the Intelligent Forces project, with the goal of simulating the behavior of civilian populations -- and insurgent forces -- on a citywide scale. If the combat shifts from Baghdad to Darfur, researchers can even plug in different cultures. Predicting the outcomes that stem from whether you ask for that raise, buy that house or quit your job for a career in animal husbandry should be easy in comparison. In the coming decades, this type of technology could be used by urban planners, video-game designers and maybe even indecisive civilians who face tough life decisions. Acoustic Cloaking Shell Long-term exposure to loud noise damages hearing and is associated with an increased risk of heart attack. So what if we were able to step into a portable sphere of pure silence? Imagine soundproofed homes perched next to freeways, expanded flight corridors for now-silent jets and quiet slices of heaven for people who work or live in noisy environments, such as city streets, construction sites or crowded coffee shops. Noise-canceling headphones already exist; they use an external microphone to detect incoming noise and then generate sounds that are 180 degrees out of phase. The two sound waves cancel each other out -- a phenomenon known as destructive interference -- but the process only works for low-frequency sound. It's a good start, but the real deal may be on the horizon. A recent article in the journal Physical Review Letters describes a theoretical material that could form a 3D "acoustic cloaking shell." Sound travels through the material at different speeds, so that incoming noise bends around the object inside and continues on as if it weren't there. Just imagine: With cheap, easily available silence, the world could finally calm down and hear itself think. Legged-Robot Everything Humans invented the wheel; Mother Nature invented legs. It was only a matter of time before we realized her design was better. The product of this epiphany? A wheelchair that can walk. Developed by Toyota, the "i-foot" prototype is an 8-ft.-tall bipedal throne that ambles, kneels and climbs stairs on backward-bending, ostrichlike legs. But let's not stop there. Picture a world of legged beds, couches and tables. People could downsize their houses to only two rooms: a storage room that holds the furniture and a main room that shifts to become whichever space is needed. Want a living room? Have the couch and coffee table walk over. Need a beer? Call the refrigerator. Feel free to mix and match: Take a bath while watching television, or cook dinner while using the treadmill. Anything is possible in the legged home of the future! Nontangling Cable A professor at the University of California San Diego recently explained the inexorable physical principles that govern the tendency of everything from rope to proteins, even DNA, to form knots. But science trumps nature. Materials called electroactive polymers change shape when supplied with electric voltage. Cables constructed with cleverly integrated electro­active polymer components could lead to headphones that don't tangle, as well as to self-straightening extension cords and garden hoses. Added bonus: fast holiday decorating. You'll never have to hunch over a hopeless mass of Christmas lights again. Insect Force Field Insects are important for healthy ecosystems, but they also ruin crops, spread disease and occasionally bite your neck -- ouch. Clearly, humankind needs a portable device capable of protecting an area from all six-legged critters. An insect force field would allow hikers to wear what they want, sleep outside the tent and come back for a dropped candy bar an hour later and find it whole. Harmful pesticides and superfluous food packaging would be a thing of the past -- so would Lyme disease and West Nile virus. Sadly, current technology is lacking: Researchers consider ultrasonic pest-control devices useless, and bug zappers -- while fun to watch -- kill the good insects with the bad. Megatracking System Ever had an iPod or camera stolen? The time is ripe for microscopic tags that can be permanently implanted into inanimate objects, so they can be tracked to whichever house/pawn shop/precinct they end up in. Prepare for greater peace of mind: With a megatracking system in place, people will think twice before walking off with your umbrella, and airlines will always know exactly where your luggage has landed. Technology is almost up to the task. Radio-frequency identification (RFID) readers can detect button-size tags from 30 ft. -- even through walls. There is a compromise, of course: your privacy. If you can track all of your possessions, chances are good that corpo­rations, governments and tech-savvy criminals can, too. Is it worth it? Maybe not. But it'd be pretty great to go swimming without having to hide your cellphone in your shoe. Kid OnStar Cars have it, so why not kids? In an automobile, GM's OnStar system is a computer that monitors car diagnostics such as engine temperature, tire pressure and whether the airbags have deployed. In the case of an accident, the system uses a built-in mobile phone and GPS tracker to contact a dispatcher who arranges to send help to stranded motorists. Similarly, Kid OnStar could be packaged into a bracelet or necklace crammed with sensors that monitor location, physiological status and voice stress levels. Parents could receive monthly diagnostic checks on exercise levels, notification if children are injured or kidnapped and the assurance that emergency services will be sent the instant a problem arises. While newer versions of OnStar allow police to automatically disable a vehicle at the touch of a button, we don't recommend this feature for Kid OnStar -- no matter how rowdy your offspring may be. Auto Memory Our brains store as memory only a fraction of what we see -- the rest is lost forever. So why can't we save our visual experiences for posterity by recording sights directly from our eyes? Photographers would snap impossible shots, eyewitnesses would accurately identify criminals and life's special moments would be stored, annotated and available for easy reference. A memory recorder might combine two existing technologies: a wearable computer that sorts and stores data (a memory prosthetic) and an implantable micromachine that intercepts and wirelessly transmits electrical activity from the optic nerve (a neuroprosthetic). With every frame of your life cataloged, this ensures you'll never forget a face again -- even if you want to.

Apple Upgrades iPhone Hardware

3G network support, GPS and improved battery life come to the next-gen iPhone. Apple CEO Steve Jobs today introduced the second-generation iPhone with new pricing and with 3G and GPS capabilities. An 8GB iPhone 3G will sell for $199 -- one-third of what the 8GB iPhone sold for at launch. A 16GB model will sell for $299, and will come in white and black versions. Sales of the new handsets will begin on July 11. Jobs made the announcements in his keynote speech kicking off this year's Apple Worldwide Developers Conference in San Francisco. Conspicuously missing from today's announcement was any mention of how much the corresponding 3G wireless services will cost. AT&T Wireless currently is the iPhone's exclusive provider in the United States, but 3G services are not part of the existing iPhone plan since the original phone doesn't support that. The iPhone 3G will be introduced in 22 countries at launch. The iPhone 3G, as its name implies, will feature support for 3G cellular networks. The original iPhone's lack of 3G support was widely criticized when that model launched last summer. GPS capability In his announcement of the new device, Jobs provided precious few details about the phone. And much of what he did announce was already expected. The biggest revelation about the new phone is its inclusion of GPS location tracking, a feature that many iPhone users insisted on for the next-gen device. Jobs was relatively quiet on the phone's physical dimensions. He made a point of calling out the iPhone 3G's thinner edges and plastic back, but he did not mention anything about its thickness (rumors pin the 3G model as being thicker than its predecessor, in order to accommodate the 3G radio and other components). The headphone jack is now flush with the upper edge of the phone -- a huge improvement over the design of the previous version, which required a kludgy plug to connect a headphone. Another enhancement over the first-generation iPhone is a boost to the device's battery life. In spite of its faster broadband data speeds, the device will offer up to 300 hours of standby time, up to 10 hours of 2G talk time (compared with eight hours on the previous model), and up to five hours of 3G talk time. "That's actually a very large amount of 3G talk time. We're very proud of this," said Jobs. The phone will run for five to six hours of high-speed Web browsing and seven hours of video viewing. Music playback is good for up to 24 hours of battery life (which puts the new iPhone right alongside stand-alone iPod audio players). Software improvements Many of the iPhone 3G's improvements will be found in its software tweaks, dubbed iPhone 2.0. For example, the phone will now support a slew of core features for enterprise security (including VPN and WPA wireless encryption). In addition, you can search through contacts, display iWork documents and Microsoft Office files, and save images received in e-mail to your photo library. It also offers batch delete and move support while in the e-mail app, and multilingual support. iPhone sales and prognosis According to Jobs, in its first year the iPhone has sold 6 million units. A whopping 98 percent of iPhone users browse the Web, 94 percent use e-mail, 90 percent do text messaging and 80 percent use 10 or more features. "You can't even begin to figure out how to use 10 features" on other phones, Jobs said. With its inclusion of a 3G radio and GPS, enterprise security and broader international support, the iPhone 3G looks well-positioned to build on Apple's market share, which climbed to 27 percent by the end of 2007, according to research firm IDC. Even with many details, such as the service costs, still unknown, Apple is clearly prepared to take on Research in Motion, maker of the popular BlackBerry smart phones. RIM currently has a 35 percent share of the smart-phone market.
