  • Patent number: 12215958
    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.
