Abstract

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.

First claim

What is claimed is:

1. A conducted electrical weapon (“CEW”) for providing a current through tissue of a target to impede locomotion of the target, the CEW comprising:
a processing circuit;
a signal generator for providing the current at a pulse rate, the pulse rate set by the processing circuit; and
two or more deployment units, each deployment unit includes two or more wire-tethered electrodes for launching toward the target to provide the current through the target to impede locomotion of the target; wherein:
the processing circuit sets the pulse rate to a first pulse rate responsive to detecting that only one deployment unit has launched electrodes; and
the processing circuit sets the pulse rate to a second pulse rate responsive to detecting that two or more deployment units have launched electrodes.

2. The CEW of claim 1 wherein the second pulse rate is greater than the first pulse rate.

3. The CEW of claim 1 wherein the first pulse rate is in a range of 15 to 30 pps, preferably 22 pps.

4. The CEW of claim 1 wherein the second pulse rate is in a range of 30 to 100 pps, preferably 44 pps.

5. The CEW of claim 1 wherein:
the first pulse rate is in a range of 15 to 30 pps, preferably 22 pps; and
the second pulse rate is in a range of 30 to 100 pps, preferably 44 pps.

6. The CEW of claim 1 wherein:
the first pulse rate is about 22 pps; and
the second pulse rate is about 44 pps.

7. The CEW of claim 1 wherein the CEW comprises two deployment units, a first deployment unit and a second deployment unit, each deployment unit includes two electrodes, wherein:
the processing circuit sets the pulse rate to the first pulse rate responsive to detecting that the electrodes of one of the first deployment unit and the second deployment unit have launched; and
the processing circuit sets the pulse rate to the second pulse rate responsive to detecting that the electrodes of the first deployment unit and the second deployment unit have launched.

8. A method performed by a conducted electrical weapon (“CEW”), the CEW for launching wire-tethered electrodes from two or more deployment units toward a target to provide a current through the target, the current for impeding locomotion of the target, the two or more deployment units removeably coupled to the CEW, the method comprising:
responsive to detecting launch of electrodes from one deployment unit, providing the current at a first pulse rate; and
responsive to detecting launch of electrodes from two or more deployment units, providing the current at a second pulse rate.

9. The method of claim 8 wherein the second pulse rate is higher than the first pulse rate.

10. The method of claim 8 wherein the first pulse rate is in a range of 15 to 30 pps, preferably 22 pps.

11. The method of claim 8 wherein the first pulse rate is in a range of 30 to 100 pps, preferably 44 pps.

12. The method of claim 8 wherein:
the first pulse rate is in a range of 15 to 30 pps, preferably 22 pps; and
the second pulse rate is in a range of 30 to 100 pps, preferably 44 pps.

13. The method of claim 8 wherein:
the first pulse rate is about 22 pps; and
the second pulse rate is about 44 pps.

14. The method of claim 8 wherein the CEW comprises two deployment units, a first deployment unit and a second deployment unit, each deployment unit includes two electrodes, wherein:
responsive to detecting launch of electrodes from one of the first deployment unit and the second deployment unit, providing the current at about 22 pps; and
responsive to detecting launch of electrodes from the first deployment unit and the second deployment unit, providing the current at about 44 pps.
