US12510320 - Dual use magazine identification wire with power routing

A communications interconnect between the countermeasure controller of a countermeasure system and the dispenser containing the countermeasure payloads therein. Additionally, the present disclosure provides a power connection between the countermeasure controller and the countermeasure dispenser to deliver power to the countermeasure payloads, including smart payloads, utilizing existing vehicle wiring harnesses and wiring kits.

The patent describes an enhanced fire select multiplexing assembly designed for a countermeasure dispenser system, which facilitates power and data transmission to countermeasure payloads using existing vehicle wiring. It includes components such as a sequencer, power control module, and transceivers, enabling the delivery of 20 W of power to multiple expendable payloads over a single fire pin pair.

Claim 1

1 . An enhanced fire select multiplexing (EFSM) assembly for a countermeasure dispenser system comprising: at least one sequencer; a 28V power control module; a first magazine identification line operable to connect the at least one sequencer and the 28V power control module to a first transceiver and a first 28V bus; a second magazine identification line operable to connect the at least one sequencer and the 28V power control module to a second transceiver and a second 28V bus; a first countermeasure expendable payload connected to the first transceiver and first 28V bus; and a second countermeasure expendable payload connected to the second transceiver and second 28V bus; wherein the EFSM assembly is configured to provide power and data transmission to at least one countermeasure expendable payload from one of the first and second countermeasure expendable payloads over a single fire pin pair; and wherein the first and second transceivers and 28V busses are operable to deliver 20 W of power to the first and second countermeasure expendable payloads. at least one sequencer; a 28V power control module; a first magazine identification line operable to connect the at least one sequencer and the 28V power control module to a first transceiver and a first 28V bus; a second magazine identification line operable to connect the at least one sequencer and the 28V power control module to a second transceiver and a second 28V bus; a first countermeasure expendable payload connected to the first transceiver and first 28V bus; and a second countermeasure expendable payload connected to the second transceiver and second 28V bus; wherein the EFSM assembly is configured to provide power and data transmission to at least one countermeasure expendable payload from one of the first and second countermeasure expendable payloads over a single fire pin pair; and wherein the first and second transceivers and 28V busses are operable to deliver 20 W of power to the first and second countermeasure expendable payloads.
