Sound familiar? That is because if you watched Doctor Who then you should know that the Doctor has this on him at all time. The sonic screwdriver from the T.V. show rendered locks useless, repaired items, cut and melded metal, scanned for information, and just do it all. This device however is not entirely out of our reach now though. Professor of Ultrasonics Bruce Drinkwater says that this device can be ushered in through the use of sonic technology. The one pocketable item which they are trying to create may not be able to render locks useless, but it will certainly be able to repair and maybe even put up a small forcefield. Doctor Who fans should hope that they can get a hold of one of the prototype models.
