Abstract: A method for incapacitating an object using a non-lethal projectile equipped with a motion sensing device. The non-lethal projectile is fired at and preferably attaches to the object. Motion of the object is monitored by the motion sensing device. Upon sensing motion of the object, the non-lethal projectile provides a first or another incapacitating stimulus to the object if the motion is sensed as meeting at least one criterion. The criterion may be based on a previously determined algorithm or the threshold is previously determined.

Abstract: An electronic circuit which provides an electrical incapacitation current to a living target. The circuit includes a high voltage power supply, a charge-storing capacitor connected by a high voltage lead to the high voltage power supply. The charge-storing capacitor stores a charge at high voltage as supplied by the high voltage power supply. The circuit further includes a switch, a step-up transformer including a primary coil a secondary coil, a resonant circuit and an output terminal serially connected through the secondary coil to the high voltage lead of the charge-storing capacitor. The primary coil is connected in parallel with the charge-storing capacitor through the switch. During the incapacitation, the output terminal is operatively attached to at least a part of the living target.

Abstract: A projectile is provided for use in a non-lethal weapon system. The projectile having kinetic energy is launched substantially along the longitudinal axis in the direction of a target. Upon impact of the projectile with the target an elastic mechanism absorbs elastically a first portion of the kinetic energy. A locking mechanism stores the first portion of the kinetic energy within the elastic mechanism; whereby the remaining kinetic energy of the impact is reduced to a non-lethal level of the target. The projectile preferably includes a deformable head attached to the first body. The deformable head is formed from a viscoelastic material which manifests both the elastic mechanism (with the elastic mechanical properties of the viscoelastic material) and further manifests the locking mechanism with the viscous properties of the viscoelastic material.
