A duration of a stimulus signal delivered to a target by a conducted electrical weapon may be selected in accordance with a current of the stimulus signal delivered to the target. The current may be measured by the conducted electrical weapon. The current may comprise a measured current of a pulse of the stimulus signal. The duration may be selected while the pulse is delivered to the target. The duration may be selected from a range of durations for which the stimulus signal may be applied. The range of durations may comprise a range of increasing pulse durations associated with a range of increasing charges provided by the stimulus signal in accordance with combinations of respective measured currents of a range of measured currents and respective pulse durations of the increasing pulse durations. A charge delivered by a measured current and a selected duration may increase as the measured current decreases.

An electric fence connection system includes a body formed with a slot have a predetermined depth. The slot may be formed to receive a polymer coated cable such that at least a portion of the polymer coated cable is surround by the body. The body may be formed to also include a first threaded aperture that extends through the body to the slot. A first threaded fastener may be sized to threadably engage the first threaded aperture. The first threaded fastener may include a head at a proximate end, a conical tip at a distal end and threads along a shaft of the fastener between the distal and the proximate end. The conical tip of the first threaded fastener may be formed to pierce the polymer coated cable positioned in the slot. The body may be formed with a second aperture formed to receive a power supply cable to supply electrical power to the polymer coated cable via the first threaded fastener.

A conducted electrical weapon (CEW) launches wire-tethered electrodes to provide a current through a human or animal target to impede locomotion of the target. The current may ionize air in a gap. A gap may occur between terminals at a face of the CEW and/or between the electrodes positioned near target tissue. A CEW may include a detector to detect ionization of air in a gap. A CEW may use information related to detecting ionization to determine a location where the ionization occurred. Information regarding location of ionization may be used to determine whether the current was delivered through the target via the electrodes.
