Subretinal implant uses light instead of batteries, shows promise in initial testing
There's been significant progress in bringing sight to the blind in recent years, and this looks set to continue that miraculous trend. Scientists at Stanford University have invented a subretinal photodiode implant for people who have lost their vision due to degenerative retinal diseases. Existing tech involves batteries and wires, but the new implant works without such crude appendages. Instead, it's activated by near-infrared beams projected by a camera that's mounted on glasses worn by the patient and can record what the patient sees. The beams then stimulate the optic nerve to allow light perception, motion detection and even basic shape awareness. It hasn't actually been tested with humans just yet, but the first few rodents volunteers have yet to lodge a single complaint.
iPhone 4 pixel density examined (video)
Sure, you've seen our iPhone 4 hands-on... but have you seen it through a retina display? We put the new device next to our trusty old iPhone 3G to get a feel just how different the screens look with twice the pixel density and shot a little pseudo-macro video. There's a marked difference in the screens, even side-by-side with the EVO 4G, and we found that even from a distance we were able to read bodies of text we'd previously had to squint to discern on our classic iPhones. Hard to capture, it really is something you have to see first-hand... but until you get that chance, live vicariously through us after the break.%Gallery-94640%
Brother, NEC look to invade your retinas next year
Brother may spend a big chunk of its time on things like printers and sewing machines, but it's also quietly been working on some decidedly more futuristic products, and it may just be set to deliver on one of them. While it wasn't offering much in the way of specifics the last time we heard about its retina display technology, Brother now seems to have a fully developed, fully functional prototype (pictured above), and it says it plans to commercialize the glasses sometime "next year." Naturally, there are a few considerable limitations compared to more traditional displays, but the company's as yet unnamed goggles do promise to beam an 800 x 600 image directly into your retina that'll appear as a 10-centimeter wide image floating about one meter in front of them -- which is certainly no small feat, even if it may not be the most practical one. Slightly less specific, but also working on a retina display of its own is NEC, which apparently hopes to incorporate a microphone into their display and use it as a real-time translation device that would quite literally display subtitles as you talk to someone. Ambitious, to be sure, but NEC is also saying it hopes to get it on the market in 2010.

Panasonic develops walkthrough iris scanner to hasten ID checks
Snappy retinal scanners have been in the works for some time, and now Panasonic is apparently hoping to hasten those annoying ID checks by enabling security personnel to confirm the true identity of a person walking through in just "two seconds." Additionally, this scanner does not require subjects to "focus on the equipment," packs "multiple two-megapixel cameras," and in case you couldn't guess, is being marketed towards airports and high-security office buildings. No word just yet on when these may be rolled out for public use, but anything (well, almost) that speeds up our traveling is smiled upon by us.[Via TechDigest]
