US12709965 - Shock resistant perforating tool for multizone completions

An apparatus for perforating a wellbore includes a plurality of perforator units that includes a first perforator unit and a second perforator unit; and a signal transfer module connecting the first perforator unit to the second perforator unit. The signal transfer module includes an enclosure having a bore, an input end, and an output end, an initiator positioned adjacent to the first perforator unit and at least partially in the enclosure, an initiator, an igniter, a fuse, and an isolator. The initiator generates a shock wave when initiated. The igniter is positioned in the enclosure and generates a low order output upon receiving the shock wave generated by the initiator. The fuse is positioned in the enclosure and is initiated by the low order output of the igniter. The fuse outputs a high order output from the output end of the enclosure. The isolator secures the fuse body in the bore of the enclosure. The isolator includes a shock attenuator. Only the shock attenuator physically connects the fuse to the enclosure.

US12352520 - Magazine ammunition rounds detection and alert module

A module for detecting and notifying of the presence of ammunition in an ammunition magazine is provided, comprising a spring and a follower for containing and advancing ammunition within the magazine. A printed circuit board having electronics mounted thereon is mounted in a handle of a gun and includes a central processing unit with access to memory having executable instruction data thereon, at least one motion sensor for sensing motion of the printed circuit board, an eccentric motor, a connector providing remote digital access to the processor, at least one mechanism for erasing data or resetting parameters, and a battery bay for accepting a battery, at least one sensor for detecting position of the spring or follower. An amount of ammunition is thereby discerned by the central processing unit based upon the position of the spring or follower.
