US12510336 - Squib enabled hold up battery switch

A countermeasure includes a cartridge case. There is an impulse cartridge (IC) cup on the cartridge case. There is a deployable payload within the cartridge case, where the deployable payload is adapted to be deployed and expelled from the cartridge case. A battery is on the deployable payload, wherein the battery is enabled to power a component on the deployable payload in response to an impulse cartridge being connected with the IC cup and the battery is disabled in response to the impulse cartridge being disconnected from the IC cup.

The patent describes a countermeasure device featuring a canister that houses a deployable payload and a battery, with a switch that alternates between active and inactive states based on interactions with the canister. The switch allows power transmission when a device is connected and prevents it when the device is disconnected, enabling controlled deployment of the payload.

Claim 1

1 . A countermeasure device comprising: a canister; a deployable payload within the canister, where the deployable payload is adapted to be deployed from the canister; a battery in the canister; and a switch in the canister that is electrically connected to the battery, wherein the switch is configured to be repeatedly switched between an active state and an inactive state based on two different interactions with the canister, wherein the active state permits transmission of power from the battery through the switch and the inactive state precludes transmission of power from the battery through the switch; wherein the two different interactions with the canister includes: a first action relative to a portion of the canister to effect the switch to operate in a first manner; and a second action relative to the portion of the canister to effect the switch to operate in a second manner; wherein the first action effects the switch to permit transmission of power through the switch and the second action effects the switch to preclude transmission of power through the switch; and wherein the first action is associated with connecting a device to the canister and the second action is associated with the disconnecting the device from the canister. a canister; a deployable payload within the canister, where the deployable payload is adapted to be deployed from the canister; a battery in the canister; and a switch in the canister that is electrically connected to the battery, wherein the switch is configured to be repeatedly switched between an active state and an inactive state based on two different interactions with the canister, wherein the active state permits transmission of power from the battery through the switch and the inactive state precludes transmission of power from the battery through the switch; wherein the two different interactions with the canister includes: a first action relative to a portion of the canister to effect the switch to operate in a first manner; and a second action relative to the portion of the canister to effect the switch to operate in a second manner; a first action relative to a portion of the canister to effect the switch to operate in a first manner; and a second action relative to the portion of the canister to effect the switch to operate in a second manner; wherein the first action effects the switch to permit transmission of power through the switch and the second action effects the switch to preclude transmission of power through the switch; and wherein the first action is associated with connecting a device to the canister and the second action is associated with the disconnecting the device from the canister.
