background checks failed in Washington, but several
entrepreneurs say they have a different answer to curbing gun
violence.  They're using technology to create guns that only
fire in the right hands. These so-called smart guns can
recognize a watch, a ring or even just a grip.  For more than a
decade, researchers at the New Jersey Institute of Technology
have been working on a grip-recognizing gun similar to the one
James Bond uses in "Skyfall."  Sensors on the grip -- similar to
the touchpad on a laptop -- measure the pressure applied and the
size and shape of the hand holding the gun.  "If a child tries
to grab the gun, their hand geometry is actually going to be
smaller," said NJIT Associate Professor Michael Recce. "So
they're not going to touch the sensors, and they're not going to
be able to fire the gun
