Cloaking device puts the kibosh on cellphone interference

by Joseph L. Flatley posted Jan 15th 2009 @ 7:59PM

There has been plenty of research into cloaking devices, but while scientists are still working their way towards the visible light spectrum they seem to be having the best luck with microwaves. Most recently, a new metamaterial made from over 10,000 individual pieces of fiberglass has been used to cloak a bump on a flat mirrored surface -- the material prevents microwaves from being scattered, giving the RADAR (we're guessing it's a RADAR) the impression that the surface is flat. This has many possible applications, such as cloaking sources of interference to cellular communications. Unfortunately, the implication we most desire -- rendering us invisible during high society jewel heists -- has yet to become reality.

Brickhouse Security's two-way micro headset may never leave your ear canal

Unlike Brickhouse Security, we won't go so far as to call this thing "invisible," but when placed in the ear, all but the most eagle-eyed among us are likely to overlook it. The elaborately named Secret Service Invisible 2-Way Micro Headset comes with an easily hidden wireless transmitter that plugs into any mobile with a 2.5-millimeter audio output. Once rigged up, the wearer can have someone listen in on conversation in a room while also receiving input from said listener. Unfortunately, this likely Jack Bauer-approved gizmo demands a practically ludicrous $649.95, so it looks like we'll be sticking to brute force and walkie talkies here. Check out a demo video after the jump -- but be sure and kill the speakers first, alright?

Scottish researchers reveal cameraphone-enabled 'invisible art'

by Darren Murph posted Aug 14th 2007 @ 3:38PM

Granted, we've already seen what wild colors can hide behind a shutter, but now a team of Scottish researchers are hoping to "bridge the virtual and real worlds" by applying invisible artwork to buildings around Edinburgh. Put simply, users who snap pictures of landmarks and MMS them back to the database can receive "an image with extras added to it." Dubbed Spellbinder, the invisible graffiti project uses image-matching algorithms to analyze the image and send back tagged snapshots of the location a user just photographed. Additionally, location projects and "virtual games" are also being looked into, which should thoroughly please both the social networking fanboys and hide-and-seek lovers alike.
