Tiny, printable batteries promise to change the face of obnoxious greeting cards forever

The always-imaginative gurus at Fraunhofer-Gesellschaft never cease to amaze, and at this year's IFA, they're delivering once more. The so-called "virtual mirror" gives to-be garb buyers an accurate look at what different outfits look like on their person without requiring them to try a single thing on. Granted, shopaholics are apt to detest this thing, but anyone with better things to do than try on four sweaters to see which one makes them look fat should be completely in love. The concept here is far from new, as we've seen both virtual makeover machines and fitting room enhancers before. Still, Fraunhofer's dream of getting you suited up and out of the store in mere minutes is one we'd love to see come true. Just don't ditch the traditional stalls too soon -- we wouldn't want any kind of worldwide uprising.
It's hardly the only one working on making lithium-ion batteries a little less likely to blow up in your face, but the prolific folks at Fraunhofer Institute seem to think that they've come up with a solid contender for your future laptop or cellphone, and they're now set to take the wraps off it at the Hannover Messe conference later this month. The key to their solution, it seems, is the use of a non-flammable polymer electrolyte instead of the liquid electrolyte now commonly used in lithium-ion batteries. While that switch cuts down on the explosiveness, it also introduced a fair number of challenges, not the least of which is the fact that polymer becomes less conductive as it gets more solid. Fraunhofer's apparently made some significant progress on that front, however, and while they're still not completely satisfied with the conductivity, they say the batteries could be ready for commercial use in three to five years. They also, not surprisingly, see no end to the uses for 'em, saying that they could not only wind up in laptops and cellphones, but power tools, lawnmowers, and potentially even cars.
Sure, it might look like a Viewmaster 3D from your childhood, but this here stripe projection 3D sensor from Fraunhofer IOF is so much less exciting. The concept is simple enough: the Kolibri projects a stripe pattern onto the subject, and then the two "eyes" capture slightly distinct angles of the image to compose a 3D model of the object based on the deducted geometry. The technology has been available for a while, but this is apparently the first device to cram it into such a small and portable form factor. Yeah... we'll stick with the Viewmaster.
Those Fraunhofer folks are nothing if not prolific, and it now looks like they're getting a little boastful as well, as evidenced by some comments reps from the group made at CES this week. As MacWorld reports, Fraunhofer IIS is not only saying that its new HD-ACC codec is "better than CD," but that it "makes CDs obsolete." That is apparently due to the codec's lossless compression of 24-bit music content, as opposed to the 16-bit, 44.1 kHz quality now found on CDs. What's more, the HD-AAC encoding process embeds a so-called "core layer" on any device that supports plain old AACs, although you'll obviously need a player with an HD-AAC decoder in order to take advantage of the fully lossless signal. Of course, some formats have a tendency to take off more quickly than others, so we'll just have to wait and see how HD-ACC plays out in the grander scheme of things.
