How far will the U.S. Patent and Trademark Office go?

A new prototype device allows the visually impaired to more easily walk the streets using sonar-like technology to create an impromptu spatial picture. Blind and visually impaired individuals may soon be walking easier with “virtual canes.” A new device developed by a team affiliated with Israel's Hebrew University allows users to detect all objects within 10 meters for safe navigation. The cane uses sonar-like technology, turning users into virtual batmen and batwomen

Professor Jeremy O'Brien, Director of the University of Bristol's Centre for Quantum Photonics, and his Japanese colleagues have demonstrated a quantum logic gate acting on four particles of light -- photons. The researchers believe their device could provide important routes to new quantum technologies, including secure communication, precision measurement, and ultimately a quantum computer -- a powerful type of computer that uses quantum bits (qubits) rather than the conventional bits used in today's computers.

The Hippo Roller has made life easier for thousands of water-starved people--but it's very expensive. The WaterWheel--designed to solve the water crisis in India--is the next generation of wheeled water carriers. Not everyone can just turn on the tap to access clean water; in the developing world, women regularly carry five-gallon, 42-pound buckets of water on their heads.

Researchers at the University of California and the Samsung Advanced Institute of Technology in Korea have been looking at the technology for two years now, and have come up with a proof-of-concept design that really could result in smell-o-vision, TV that pumps out odors to heighten to your immersive-TV experience. Nasal nostalgia is made possible by your brain's hippocampus --where long-term memories get sorted out--and it seems it's a very primal instinct, which may explain its power. You know what I mean: The way an unexpected whiff of scent will spark off memories of a long-forgotten partner

A survey reveals that 70% of slate-style computer owners fiddle with them while watching television. How long before we don't need one of those small screens at all? Good night and good luck, indeed.

(PhysOrg.com) -- One of the most difficult problems for designing mobile devices is finding a way to minimize the size of the device while simultaneously maximizing the size of the display. To get the best of both worlds, researchers from the Samsung Advanced Institute of Technology in South Korea have designed and built a prototype of a seamless foldable display that folds in half without a visible crease in the middle.

The electrical energy from the vibrations caused by a human voice can be harvested--and one day could be used to charge your cell phone. The catch

A real-life version of the tracking devices seen on detective shows, the Garmin GTU 10 lets you keep tabs on prized possessions. The waterproof GPS transmitter, which is roughly the size of a cigarette lighter and weighs 1.7 ounces, comes with a case, a carabiner ring, and an adhesive strip for attaching it to objects—a briefcase, say, or a dog collar

1. Darling of the social media scene Twitter just revealed some stats for its recent performance, and they're pretty eye-popping: Over the first quarter of 2011 Twitter's tweet-per-day count grew 41% globally, and 38% in the U.S. Meanwhile from December to March there was a 52% increase in monthly sign-ups, and 155 million tweets per day are going on, up from 55 million at the same time last year.

Two intriguing rumors have popped up at almost the same time: A number of photos of an assumed iPod Touch that has no physical home button, hinting at the iPhone 5, and a keypad-less HP device that could be the webOS clone of Apple's invention. Website PreCentral , which secured early images of the Verizon Pre 3, has published images of what seems to be a keyboard-less Pre smartphone, with a screen slightly larger than earlier Pre devices and what seems to be a front-facing camera set off-center at the top of the phone. According to earlier leaked data, the device could be codenamed the Stingray (the Pre 3 was codenamed Mantaray).
