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.

First claim

What is claimed is:

1. A conducted electrical weapon (“CEW”) for delivering 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 first processing circuit, a power supply, a signal generator for producing the current, and a plurality of bays, each bay includes a coupler;
a plurality of deployment units, each deployment unit includes a second processing circuit, a coupler, and at least two wire-tethered electrodes for launching toward the one or more targets to provide the current, each deployment unit configured to be inserted into any one bay so that one or more bays may hold a respective deployment unit; wherein for each deployment unit inserted into one bay:
the coupler of the bay physically contacts the coupler of the deployment unit to electrically couple the handle to the deployment unit for transferring data between the handle and the deployment unit;
the first processing circuit sends a first data to the second processing circuit;
the second processing circuit encodes the first data to create an encoded first data and sends the encoded first data to the first processing circuit;
the first processing circuit examines the encoded first data to authenticate the deployment unit; and
responsive to authentication, the first processing circuit indicates that the deployment unit is available for launching the at least two electrodes of the deployment unit toward the one or more targets to provide the current through the one or more targets to impede locomotion of the one or more targets.

2. The CEW of claim 1 wherein the coupler of the bay provides power from the power supply to the second processing circuit of the deployment unit.

3. The CEW of claim 1 wherein:
the first and second processing circuits each encode the first data using a predetermined algorithm; and
the first processing circuit authenticates the deployment unit by comparing the encoded first data from the second processing circuit with data encoded by the first processing circuit.

4. The CEW of claim 1 wherein:
the deployment unit further includes a memory;
the first processing circuit sends a second data to the second processing circuit, the second data includes a fired status indicating that the deployment unit has been deployed; and
the second processing circuit stores the fired status in the memory.

5. The CEW of claim 4 wherein the fired status stored in the memory is unalterable after being stored.

6. The CEW of claim 1 wherein:
the first processing circuit sends a request for a second data to the second processing circuit; and
responsive to the request for the second data, the second processing circuit sends the second data wherein the second data includes indicia about the deployment unit.

7. The CEW of claim 6 wherein the indicia includes at least one of manufacturer, data of manufacture, deployment unit type, revision, expiration data, unique identifier, and fired status.

8. A deployment unit that cooperates with a provided handle to deliver a current through a provided human or animal target to impede locomotion of the target, the deployment unit comprising:
a coupler;
a processing circuit;
two or more wire-tethered electrodes; and
a pyrotechnic; wherein:
the deployment unit is configured for inserting into any one bay of the handle;
while the deployment unit is inserted into the one bay, the processing circuit receives power via the coupler for performing one or more operation;
the processing circuit receives a data from the handle via the coupler;
the processing circuit encodes the data to create an encoded data;
the processing circuit transmits the encoded data to the handle via the coupler, the encoded data for enabling the handle to authenticate the deployment unit;
responsive to authentication, a launch signal from the handle ignites the pyrotechnic for launching the two or more wire-tethered electrodes toward the target; and
a stimulus signal from the handle is delivered through the target via the launched wire-tethered electrodes to impede the locomotion of the target.

9. The deployment unit of claim 8 further comprises a memory for storing deployment unit indicia, wherein the indicia includes at least one of manufacturer, data of manufacture, deployment unit type, revision, expiration data, unique identifier, and fired status.

10. The deployment unit of claim 9 wherein the fired status is unalterable after being set to fired.

11. The deployment unit of claim 8 further comprising a first electrical ground and a second electrical ground wherein:
the first electrical ground provides a first voltage reference for the processing circuit; and
the second electrical ground provides a second voltage reference for the launch signal.

12. The deployment unit of claim 8 further comprises a memory wherein:
responsive to receiving the launch signal, the processing circuit receives a second data that includes a fired status indicating that the deployment unit has been deployed; and
the processing circuit stores the fired status in the memory.

13. The deployment unit of claim 8 wherein:
responsive to a request from the handle, the processing circuit provides a second data to the handle; and
the second data includes indicia about the deployment unit.

14. 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, the handle comprising:
a plurality of bays, each bay includes a coupler, each bay configured to receive one deployment unit so that one or more bays hold a respective deployment unit, each deployment unit includes a coupler;
a processing circuit;
a power supply; and
a signal generator for provide the current; wherein:
while one deployment unit is inserted into one bay of the plurality, the coupler of the one bay physically contacts the coupler of the one deployment unit to electrically couple the handle to the one deployment unit for transferring data between the handle and for the power supply to provide power to the one deployment unit;
the processing circuit provides a data to the one deployment unit;
the processing circuit receives an encoded data from the one deployment unit, the data is encoded by the one deployment unit to create the encoded data;
the processing circuit uses the encoded data to authenticate the one deployment unit; and
responsive to authentication, the processing circuit indicates that the deployment unit inserted into the one bay is available for launching at least two electrodes toward the target to provide the current through the target to impede locomotion of the target.

15. The handle of claim 14 wherein the processing circuit encodes the data provided to the deployment unit to compare with the encode data from the deployment unit for authentication.

16. The handle of claim 14 wherein the processing circuit requests deployment unit indicia from the one deployment unit, the indicia includes at least one of manufacturer, data of manufacture, deployment unit type, revision, expiration data, unique identifier, and fired status.

17. The handle of claim 14 wherein the data provided to the one deployment unit further includes deployment status.
