Please remove all jewelry: Nokia files metal detector patent

Chris Ziegler

Here's a patent filing from the creative minds at Nokia that'll appeal to both the security industry and the paranoid among us. Apparently, with a little elbow grease, bubble gum, and duct tape, engineers have been able to take your standard induction coil used for hearing aid compatibility and give it the functionality of a close-range metal detector. At least, that was the intent of Nokia's patent filing back in 2004. Of course, we've seen enough phone patents come and go to know that the odds we'll see this in a shipping product any time soon are low, so in the meantime, keep your distance from knife-wielding baddies, m'kay?
