The present invention relates to an electrified riot protection shield for keeping law enforcement officers safe while deterring rioters. The shield is designed as a multi-person shield and can be used by a plurality of security officers to shield their bodies, such that when one or more protestors touch a front surface of the shield, a non-lethal electric shock is administered to the protestor's body to deter the protestor or rioter. The shield can be held in front of the officers' bodies by grasping the insulated handles disposed on a rear surface of the device and an electric supply is provided to a metal plate from an integrated battery for providing the electric shock. A trigger is actuated to enable the electric supply to the metal plate and the trigger can be actuated when the metal plate is pushed or touched by a protestor.

An electric fence energizer including an IPC (isolated power coupling) power transmitter and an IPC power receiver adapted to receive power from the IPC power transmitter and supply power to the energizer. A pulse shaping circuit between an energy source and output transformer of the energizer may include a series inductance of between 2 μH to 20 μH and a parallel capacitance of between 3μF to 30 μF. The energizer output transformer may comprise a primary winding consisting of less than 15 turns and a secondary winding of between 5 and 50 times the number of turns of the primary winding. The energizer may produce a pulse having a duration of between 20 μs and 60 μs and a peak amplitude greater than 5 kV into 300 Ω.

A conducted electrical weapon (“CEW”) launches wire-tethered electrodes from multiple cartridges to provide a current through a human or animal target to impede locomotion of the target. The CEW may detect when the electrodes launched from the cartridges may provide the current through more than one target. The CEW may detect when electrodes launched from the cartridges may provide the current through the same target. The CEW may set the pulse rate of the current based on detecting the launch of electrodes from more than one cartridge, detecting that electrodes may provide the current through two or more targets, and/or detecting that two or more pairs of electrodes may deliver the current through the same target.

The device for applying an electrical pulse includes at least one glove having a glove body ending in glove fingers, at least three of which are provided with first application contacts, connected to an electrical energy source via a control unit. The glove further includes second application contacts. The control unit includes a selector for applying a differential electrical pulse between the first and second application contacts.

Systems and methods for calibrating a conducted electrical weapon (“CEW”) to provide a predetermined amount of current for each pulse of the stimulus signal. Providing the predetermined amount of current, close thereto, increases the effectiveness of the stimulus signal in impeding locomotion of a human or animal target. The calibration process enables a CEW to calibrate the amount of charge in a pulse of the stimulus signal in the environmental conditions where the tester operates and also in the field where the environmental conditions may be different from the environmental conditions during calibration.

A conducted electrical weapon (“CEW”) launches wire-tethered electrodes from multiple cartridges to provide a current through a human or animal target to impede locomotion of the target. The CEW includes a handle and one or more deployment units. A handle and each deployment unit include a processing circuit and memory. The processing circuit of a handle may communicate with the processing circuit of the one or more deployment units. The processing circuit in a deployment unit may confirm receipt of a message from the processing circuit in a handle. A handle may provide operation and usage data to a deployment unit for storage. A handle may receive data from a deployment unit.
