Abstract: An inflatable flotation device includes an inflatable body configured to be stored in a deflated state and to be inflated in response to an event. The inflatable flotation device also includes a switch attached to the inflatable body and configured to switch from an off state to an on state in response to the inflatable body being inflated at least one of to or beyond a predetermined inflation level. The inflatable flotation device also includes a speaker attached to the inflatable body, electrically coupled to the switch, and configured to generate an audio signal indicating that the inflatable body is ready for use in response to the switch being switched from the off state to the on state.

Abstract: A canopy support for an inflatable evacuation device may comprise a first canopy support segment and a second canopy support segment configured to fit at least partially within the first canopy support segment when the canopy support is in a stowed state and configured to interlock with the first canopy support segment in an extended position when the canopy support is in a deployed state. The first canopy support segment may include a first interlocking portion. The second canopy support segment may include a second interlocking portion. The second interlocking portion may be configured to mate with the first interlocking portion.

Abstract: An aspirator includes an aspirator body having at least one flapper door designed to allow intake of a gas from an environment of the aspirator. The aspirator also includes an aspirator barrel having an end tip, a compressible spring, and a fabric positioned about the compressible spring, and designed to extend in response to receiving the gas and to transfer the gas from the aspirator body to the inflatable flotation device. The aspirator also includes a gas valve designed to receive a fluid from a compressed fluid source. The aspirator also includes a nozzle positioned within the aspirator body, coupled to the gas valve, and designed to receive the fluid via the gas valve and to direct at least a portion of the fluid towards the aspirator barrel such that the at least one flapper door allows the gas to flow from the environment into the aspirator barrel.
