secure luggage
use distance sensing device to get alarm if luggage is being stolen or forgotten | |
use two wireless gadgets which constantly sense distance between them. if the distance increases beyond the limit (say 3 meters) then the alarm rings reminding that other gadget which is in luggage is being lost.
one can think of one of the devices as mobile phone(master device) and other to be kept
with luggageas slave device.
in advanced version the minimum distance between the gadgets can be altered to suit the situation.
this will effectively curb thefts or loss of luggage in cabs,at airports or in railways,public places etc.
If it's not in here it should be.

I'm going to hazard that [phoenix] has shown this idea to be redundant. |
