Abstract

Magazines of conducted electrical weapons (CEW) comprise a set of magnetic elements having positions, polarities, and magnitudes corresponding to a type of magazine. The CEW uses sensors to detect an indicator magnet indicating that a magazine is inserted into a bay of the CEW. The CEW additionally uses sensors to detect information about the set of magnetic elements and determines, based on the detected information, a type of the magazine.

First claim

What is claimed is:

1. A method comprising:
receiving, by a conducted electrical weapon (“CEW”), a magazine into a bay of the CEW;
detecting, by the CEW, an indicator magnet having a first respective position on the magazine and a first respective polarity;
performing, by the CEW, a check for one or more magnetic elements responsive to the indicator magnet being detected, the one or more magnetic elements having one or more second respective positions on the magazine and one or more second respective polarities; and
determining, by the CEW and based at least in part on the one or more magnetic elements, a magazine type of the magazine.

2. The method of claim 1 , wherein the one or more magnetic elements comprise three magnetic elements.

3. The method of claim 1 , wherein determining the magazine type of the magazine is based at least in part on the one or more second respective polarities of the one or more magnetic elements.

4. The method of claim 1 , wherein determining the magazine type of the magazine is based at least in part on the one or more second respective positions of the one or more magnetic elements.

5. The method of claim 1 , wherein determining the magazine type of the magazine comprises accessing, by the CEW, a data store of the CEW, the data store of the CEW comprising a mapping of information about the one or more magnetic elements and a corresponding magazine type.

6. The method of claim 1 , further comprising displaying, by the CEW, information about the magazine type of the magazine for display to a user of the CEW.

7. The method of claim 1 , further comprising modifying, by the CEW, one or more parameters of operation of the CEW based at least in part on the magazine type of the magazine.

8. The method of claim 1 , wherein the one or more second respective positions are one or more fixed positions and the one or more second respective polarities are one or more fixed polarities of the one or more magnetic elements.

9. A conducted electrical weapon (“CEW”) comprising:
a bay configured to receive a magazine;
a memory configured to store information about one or more magazine types; and
a processor communicatively coupled to the memory and configured to perform steps comprising:
detecting an indicator magnet having a first respective position on the magazine and a first respective polarity;
determining, based at least on the indicator magnet, that the magazine is within the bay;
performing a check for one or more magnetic elements responsive to the indicator magnet being detected, the one or more magnetic elements having one or more second respective positions on the magazine and one or more second respective polarities; and
determining, based at least in part on the one or more magnetic elements, a magazine type of the magazine.

10. The CEW of claim 9 , wherein performing the check for the one or more magnetic elements is performed responsive to detecting the indicator magnet.

11. The CEW of claim 9 , wherein determining the magazine type of the magazine is based at least in part on the one or more second respective polarities of the one or more magnetic elements.

12. The CEW of claim 9 , wherein determining the magazine type of the magazine is based at least in part on the one or more second respective positions of the one or more magnetic elements.

13. The CEW of claim 9 , wherein determining the magazine type of the magazine comprises accessing the memory of the CEW, the memory of the CEW comprising a mapping of information about the one or more magnetic elements and a corresponding magazine type.

14. The CEW of claim 9 , wherein the processor is further configured to modify one or more parameters of operation of the CEW based at least in part on the magazine type of the magazine.

15. The CEW of claim 9 , further comprising a sensor configured to at least in part perform the check for the one or more magnetic elements.

16. The CEW of claim 15 , wherein the sensor comprises a hall effect sensor.

17. The CEW of claim 9 , wherein determining the magazine type of the magazine comprises establishing, by the CEW, a communication channel with a remote entity and receiving, from the remote entity, a mapping of information about the one or more magnetic elements and a corresponding magazine type.

18. The CEW of claim 9 , wherein the processor is further configured to display information about the magazine type of the magazine for display to a user of the CEW.

19. The CEW of claim 18 , wherein the information about the magazine type comprises a number of cartridges the magazine can receive.

20. The CEW of claim 18 , wherein the information about the magazine type comprises an identifier of the magazine type.
