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 includes a handle and one or more deployment units. A handle and each deployment unit include a processing circuit and memory. A handle may provide operation and usage records to a deployment unit for storage. The information stored on a deployment unit may be unalterable once written. A handle may log a record of usage, deployment units, and other deployment information. The log file may be available to an electronic device through a secure wireless protocol.

Claims

1. A conducted electrical weapon (“

CEW”

) for providing a current through one or more provided targets to impede locomotion of the one or more targets, the CEW comprising;

a handle, the handle includes a processing circuit, a signal generator for providing the current, a first user-operated control, a second user-operated control, and a plurality of bays, each bay includes a coupler;

one or more deployment units, each deployment unit includes a coupler, a pyrotechnic and at least two wire-tethered electrodes, the pyrotechnic for launching the at least two wire-tethered electrodes, each deployment unit configured to be inserted into any one bay so that one or more bays hold a respective deployment unit;

wherein;

responsive to an operation of the first user-operated control, the processing circuit serially polls each bay to determine whether one of the deployment units is inserted into the bay;

upon detecting one of the deployment units inserted into the bay, the processing circuit;

sends data to and receives data from the deployment unit via the coupler of the bay and the coupler of the one deployment unit; and

marks the bay as holding the one deployment unit; and

after polling each bay and in response to each operation of the second user-operated control, the processing circuit successively selects one marked bay to launch the at least two electrodes from the one deployment unit in the marked bay toward the one or more targets to provide the current from the signal generator through the one or more targets.

2. The CEW of claim 1 wherein the first control comprises a safety switch to arm and disarm the CEW.

3. The CEW of claim 1 wherein the second control comprises a trigger switch.

4. The CEW of claim 1 wherein the data received by the processing circuit from the deployment unit includes a unique identifier of the deployment unit.

5. The CEW of claim 1 wherein the data received by the processing circuit from the deployment unit includes an encoded response to the data sent to the deployment unit, the encoded response for authenticating the deployment unit.

6. The CEW of claim 1 wherein the data is communicated bidirectionally via the coupler of the bay and the coupler of the deployment unit.

7. A conducted electrical weapon (“

CEW”

) for providing a current through a provided human or animal target to impede locomotion of the target, the CEW comprising;

a handle, the handle includes a processing circuit, a signal generator for providing the current, a first user-operated control, a second user-operated control, and a plurality of bays;

one or more deployment units, each deployment unit includes a pyrotechnic and at least two wire-tethered electrodes, the pyrotechnic for launching the at least two wire-tethered electrodes, each deployment unit configured to be inserted into any one bay so that one or more bays hold a respective deployment unit;

wherein;

responsive to an operation of the first user-operated control, the processing circuit serially polls each bay to determine whether one of the deployment units is inserted into one of the bays;

upon detecting one of the deployment units inserted into one of the bays, the processing circuit;

authenticates the deployment unit in the bay; and

responsive to authentication, marks the bay as holding one deployment unit; and

after polling each bay and in response to each operation of the second user-operated control, the processing circuit successively selects one marked bay for launching the at least two electrodes from the deployment unit in the selected bay toward the target to provide the current from the signal generator through the target.

8. The CEW of claim 7 wherein the first control comprises a safety switch to arm and disarm the CEW.

9. The CEW of claim 7 wherein the second control comprises a trigger switch.

10. A handle that cooperates with a plurality of provided deployment units to provide a current through a provided human or animal target to impede locomotion of the target, each deployment unit includes at least two provided electrodes for providing the current, the handle comprising:

a processing circuit;

a signal generator for providing the current;

a first user-operated control;

a second user-operated control; and

a plurality of bays for respectively receiving one of the deployments;

wherein;

responsive to an operation of the first user-operated control, the processing circuit polls each bay to determine whether one of the deployment units is inserted into the bay;

upon detecting one of the deployment units inserted into one of the bays, the processing circuit;

receives data from the deployment unit in the bay for authenticating the deployment unit;

marks the bay as holding one deployment unit; and

in response to each operation of the second user-operated control, the processing circuit successively selects one marked bay for launching the at least two electrodes from the deployment unit in the selected bay toward the target to provide the current from the signal generator through the target.

11. The handle of claim 10 wherein the first control comprises a safety switch to arm and disarm the handle.

12. The handle of claim 10 wherein the second control comprises a trigger switch.

13. The handle of claim 10 wherein the data received from the deployment unit for authenticating is encoded data.

14. The handle of claim 10 wherein the processing circuit includes a memory for recording which bays are marked as holding one deployment unit.

15. The handle of claim 14 wherein the processing circuit records which marked bays have fired the deployment unit.
