Personal Security Backpack

Guardian Backpacks are inconspicuously equipped with the world's loudest personal alarm system to attract immediate attention to dangerous or harmful situations.

Constructed like any standard backpack commonly used by students, the Guardian Backpack is designed to simultaneously emitt two 130 decibel sirens that can be heard within a 100 yard radius and a high intensity strobe light that can be seen up to 400 yards away. The sirens are positioned in the lower outer section of the backpack, directed away from the user to prevent hearing damage.

The alarm system can run up to five continuous hours before replacing the batteries.

Actually a good idea. Put a

Actually a good idea. Put a lojac on the kid with this and you might have something. The alarm will initially startle the criminal and the kid has to rehearse this potential life-threatening scene with the parents. This startling moment is when the kid needs to run away - fast! Some of these wonderful inventions can be best utilized with other life-saving inventions - like daveanne's idea of putting a 911 dialer into the mix. This is a good start as long as the kid knows what to do and is aware of "bad guys."

You didn't mention how it's activated. Also I like this but limits the user for what bag they are using. Would be better as a portable device.

But that gives you a problem with getting the unit to be on the outer side of the bag.

How about a leg band unit that just stays around your leg water proof and needs a key to be removed. Also you could make it not turn of until the small key is inserted in to the unit.

That way a kid doesn't get jumped and then they turn it off. If you want to go even more than that.

GPS signal sending. Send a message to a preselected mobile alerting the person where the ban is. You could program it via usb or blue tooth as there small these days. I don't know how small GPS devices can be, and also power consumption would be a factor to take in to account as you wouldn't want a brick around your leg.
