Here's an odd product from Samsung-Italia. It's the Fidobag
. The site explaining the Fidobag is in Italian, but apparently it's a suitcase that will respond to the voice of its owner and come at their command (that would be useful for finding a bag in an airport). Also, if someone tries to steal your bag, all you need do is call out and the Fidobag will start to 'bark' at an intensity of 197.5 decibels, thereby stunning and exposing the would-be thief. Gizmodo
offers a more complete translation of the site. Although the Fidobag does seem like it would be useful, it just seems way too odd to actually be real.

Also I'm trying to imagine: So I try to steal this thing and it's starts to growl....so WHAT. What's it gonna do bite me????
Even if it were real: not a very good design 😊
130 dB = air raid siren at 1 meter
140 dB = jet engine
150 dB = instant perforation of eardrum
180 dB = shuttle launch at ground zero
If this thing barks at 197.5 dB it would cause internal organ damage to anybody unfortunate enough to be near it. I don't know of anything that can emit a sound that loud other than a very large explosion. Must be a total hoax.
Shucks, why not just put an atomic bomb in the darned bag?
