Bad news for the insurgency

Maybe not by next week, but if this technology comes to fruition, it will help our military in the near future since they will be fighting these islamists for some time on our behalf.

New Scientist Tech - Breaking News - Invention: Bomb jammer:
Jimmy Hendrix turned feedback into an art form – sticking his guitar close to a speaker so that it picked up its own sound and generated deafening shrieks.

Now a US inventor is patenting a way to defeat remote-controlled explosives using the same trick. A series of transmitters would create a self-sustaining bubble of radio frequency noise to prevent terrorists from sending a trigger signal to a hidden bomb."

In his patent filing, James Cornwell of Virginia, US, claims that existing radio jamming devices are flawed because they leave gaps that let trigger signals sneak through. His system would use up to four radio transmitters and receivers placed around a risk area. When a wide frequency of noise is fed to one of the transmitters, all the receivers pick it up and feed the signal to their respective transmitters. Soon the feedback loop completely blankets the risk area with powerful radio energy.

The method could produce a bomb-blocking bubble up to 1 kilometre square, Cornwell reckons. This would leave bomb disposal experts safe in the knowledge that no one could trigger an explosive device while they are working to defuse it.
