A conducted electrical weapon (CEW) launches wire-tethered electrodes from one or more 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 one or more cartridges, 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 present invention relates to a remotely triggered improved electrical stimulus circuit to be worn by cattle that is lightweight and can store voltage lower than what is to be supplied to an animal. Known cattle electrical stimulus collars may be heavy, use a lot of energy, and not supply a consistent electrical stimulus. The present electrical stimulus circuit utilizes feedback loops to allow the use of high tolerance lightweight capacitors, and/or cool down periods to utilize a highly inefficient transformer running fully saturated.

An electric fence energizer comprising an energy storage capacitor (2), which is able to be discharged into the primary (3) of a step-up transformer, the secondary (4) of which is connected to the electric fence, and comprising an internal electronic control device for controlling the discharge pulses from the capacitor (2) to the electric fence. The capacitor (2) is discharged into a circuit consisting, in series and in the following order, of a first electronic actuator (5), followed by the primary (3) of the transformer, followed by a second electronic actuator (6), the opening and closing of each one of the two electronic actuators (5, 6) being able to be controlled, and each one of said electronic actuators being able, during discharging, to interrupt the discharge pulses from the capacitor (2) into the primary (3) of the transformer, and then to permit said pulses.

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.
