  **_Slowshields_ :** A Korozhet device implanted subcutaneously, just above the
  breastbone of a mammal user. The device remains inactive, except for
  maintaining an ovoid spherical perimeter fieldjust outside of the reach of
  the userfor which it draws energy from the body heat of the user. If an
  object moving at greater than 22.8 mph impinges on the perimeter field, the
  slowshield device strips all the kinetic energy from this object. Effectively,
  the projectile will simply fall. The energy absorbed cannot be contained by
  the slowshield device. The device wastes the energy by projecting a hardshield
  (a force field). The time the hardshield is active for depends on the amount
  of kinetic energy absorbed. The slowshield device has a particle-size acceptor
  program. Should two slowshields intersect, a twin focus develops, making a
  larger perimeter than both combatants.
