Handheld Weapon Including Projectile Interceptor

New devices, systems and methods are provided for protecting personnel and/or equipment from projectile(s) and/or weapons. In some embodiments, one or more actuator(s) mounted on a handheld combat device project shielding materials, such as particles and surfaces, to intercept one or more such projectile(s) or weapon(s). In some embodiments, such actuator(s) include electromagnets or a propellant, for driving the interception particles and surfaces away from the protected personnel and/or equipment. In some aspects of the invention, a control system using sensors with one or more sampling points are included, and determine the location and probable trajectory(ies) of an incoming projectile, and deploy the interception particles and surfaces to intercept the incoming projectile or other weapon.
