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. 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.

First claim

What is claimed is:

1. A handle for a conducted electrical weapon (“CEW”) comprising:
a bay configured to receive a deployment unit; and
a processing circuit in communication with the bay, wherein the processing circuit is configured to:
detect whether the deployment unit is inserted into the bay,
at least one of send a first data to or receive a second data from the deployment unit,
authenticate the deployment unit based on the at least one of send the first data to or receive a second data from the deployment unit, and
mark the bay as containing the deployment unit.

2. The handle of claim 1 , further comprising a safety in communication with the processing circuit, wherein the processing circuit is configured to detect whether the deployment unit is inserted into the bay in response to the safety being activated.

3. The handle of claim 1 , further comprising a battery pack configured to be inserted and removed from the handle, wherein the processing circuit is configured to detect whether the deployment unit is inserted into the bay in response to the battery pack being inserted into the handle.

4. The handle of claim 1 , further comprising a memory in communication with the processing circuit, wherein the processing circuit is configured to write the bay as containing the deployment unit in the memory.

5. The handle of claim 1 , wherein the processing circuit is configured to at least one of send the first data to or receive the second data from the deployment unit for error detection, error correction, read messaging or write messaging, identity messaging, or status messaging.

6. The handle of claim 1 , wherein the second data comprises at least one of a unique identifier, a manufacturer name, a manufacturer number, or a device type.

7. The handle of claim 1 , wherein the second data comprises an encoded data, and wherein the processing circuit is configured to authenticate the deployment unit based on the encoded data.

8. The handle of claim 1 , wherein the processing circuit is configured to detect whether the deployment unit is inserted into the bay by serially polling the bay.

9. A deployment unit for a conducted electrical weapon (“CEW”) comprising:
a coupler;
an electrode; and
a processing circuit, and wherein in response to the deployment unit being inserted into a CEW handle the processing circuit is configured to:
receive a first data from the CEW handle, and
transmit a second data back to the CEW handle, wherein the second data is used by the CEW handle for at least one error detection, error correction, authentication, read messaging or write messaging, identity messaging, or status messaging.

10. The deployment unit of claim 9 , wherein the processing circuit is configured to receive power from a power supply of the CEW handle.

11. The deployment unit of claim 9 , wherein the second data comprises at least one of a unique identifier, a manufacturer name, a manufacturer number, or a deployment unit type.

12. The deployment unit of claim 9 , wherein the second data comprises an encoded data, and wherein the CEW handle is configured to authenticate the deployment unit based on the encoded data.

13. The deployment unit of claim 9 , further comprising a memory in communication with the processing circuit, wherein the memory is configured to store at least one of a manufacturer, data of a manufacture, a deployment unit type, a version, an expiration data, a unique identifier, or a first status.

14. A conducted electrical weapon (“CEW”) comprising:
a handle comprising:
a processing circuit;
a power supply;
a bay; and
a signal generator configured to provide an electrical signal; and

a deployment unit removably inserted within the bay, the deployment unit comprising an electrode configured to be launched from the deployment unit, wherein the processing circuit is configured to:
poll the bay to determine whether the deployment unit is inserted within the bay,
mark the bay as holding the deployment unit,
select, based on the mark, the bay, and
instruct, based on the select, the signal generator to provide the electrical signal to the deployment unit.

15. The CEW of claim 14 , wherein the handle further comprises a trigger, and wherein the processing circuit is configured to instruct the signal generator to provide the electrical signal to the deployment unit in response to operation of the trigger.

16. The CEW of claim 15 , wherein the electrical signal is configured to cause the electrode to be launched from the deployment unit.

17. The CEW of claim 14 , wherein the processing circuit is configured to store a record that includes indicia of an activation of the deployment unit.

18. The CEW of claim 17 , wherein the record comprises the bay marked by the processing circuit that housed the deployment unit during the activation of the deployment unit.

19. The CEW of claim 17 , wherein the indicia of the activation comprises a fired flag.

20. The CEW of claim 14 , wherein the bay comprises a plurality of bays, and wherein the processing circuit is configured to poll each of the plurality of bays.
