Patent number: 9958242Abstract: A payload dispersion system for a non-lethal projectile including a resilient layer and a marker packet having a hollow body including a lower surface, at least a partial opening centrally disposed, an upper surface, a volume formed by the lower surface, the at least a partial opening and the upper surface and a payload contained within the volume. The upper surface of the marker packet includes a wall and at least one weakened portion within the wall. The lower surface of the marker packet contacts an upper surface of the resilient layer.Type: GrantFiled: July 13, 2016Date of Patent: May 1, 2018Assignee: Security Devices International Inc.Inventors: Gregory Barry Sullivan, Dean Gregory Thrasher

Patent number: 8342098Abstract: A projectile launched from a conventional weapon; upon impact with a human target the projectile attaches to the target and stuns and disables the target by applying a pulsed electrical charge. The electric round is defined as non lethal ammunition directed to incapacitate a human, to prevent him from moving for a short time, to prevent him from committing a crime and to allow authorized personnel to arrest the target. A novel thin film technology transformer and thin film technology battery produce an electrical shock capable of stunning a human being in a device the size of a conventional bullet. The transformer and battery are smaller and lighter than conventional transformers and batteries with similar power output.Type: GrantFiled: June 12, 2006Date of Patent: January 1, 2013Assignee: Security Devices International Inc.Inventors: Ilan Shalev, Matwey Bereznitsky, Haim Danon, Nathan Blaunstein, Ginnadii Swarzshtein

Patent number: 8336462Abstract: 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.Type: GrantFiled: March 23, 2009Date of Patent: December 25, 2012Assignee: SDI - Security Device International Inc.Inventors: Haim Danon, Ilan Shalev

Patent number: 8111498Abstract: 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.Type: GrantFiled: July 9, 2008Date of Patent: February 7, 2012Assignee: SDI - Security Device International Inc.Inventor: Shmuel Ben-Yaakov

Patent number: 8061276Abstract: A projectile is provided for use in a non-lethal weapon system. The projectile includes a first body with a longitudinal axis. The projectile having kinetic energy is launched substantially along the longitudinal axis in the direction of a target. The projectile preferably includes a second body with the same longitudinal axis and a hollow. A portion of the first body fits marginally within the hollow. The elastic mechanism includes an elastic deformation of the first body and/or second body while the first body is forced into the hollow during the impact.Type: GrantFiled: November 23, 2010Date of Patent: November 22, 2011Assignee: SDI—Security Device International Inc.Inventors: Haim Danon, Ilan Shalev

Patent number: 7861657Abstract: 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.Type: GrantFiled: March 31, 2008Date of Patent: January 4, 2011Assignee: SDI - Security Device International, Inc.Inventors: Haim Danon, Ilan Shalev
