An inline for an inflatable assembly may comprise a first end defining a primary gas inlet and a second end defining a primary gas outlet. An internal surface may define a flow path extending from the primary gas inlet to the primary gas outlet. An orifice may be located between the first end and the second end. The orifice may be defined, at least partially, by a radial wall extending from the internal surface to the external surface. The orifice may be configured to entrain ambient air with a primary gas flowing from the primary gas inlet to the primary gas outlet.

The invention discloses a self-rescue device for an automatic driving door when a car is drowning. It includes a first body, a hollow slider is threadedly installed on the threaded screw, and the first rotation shaft is located in the first sliding space to rotate and install a first A universal joint, the other side of the first universal joint is rotationally connected to the right-hand threaded screw, and a motor is used to drive and control the three-position threaded screw to adjust the position of the safety hammer. Save time in time, and the edge of the glass is the easiest to break, so it can be extended to the edge of the glass in a short period of time, greatly increasing the chance of survival, and a life buoy is stored in the middle, which can be used in a short time in an emergency Time to quickly inflate the lifebuoy to give people who can't swim a little vitality.

An emergency location information service (E-LIS) for water-based network devices. The E-LIS includes a server application and server network devices that accepts emergency messages from water-based network devices. The water based network devices comprise one or more sensors or one or more actuators, a wireless connection interface including a wireless low power wide-area ultra-narrowband network interface and a wireless low earth orbit satellite network connection interface and is an automated network device capable of sensing is own environment and automatically sending out the one or more emergency messages or one or more emergency text messages without operator input to an E-LIS server network device when an emergency event occurs on a body of water. The E-LIS server network device provides a current physical geographic location for such water-based network devices and/or users of the water-based network devices in an emergency situation on the body of water such as a river, lake, sea, ocean, etc.

A portable safety device (100) for inflating multiple envelopes includes at least one inlet for surrounding air (1), at least one inflation system, at least one enriched air or gas zone, at least one nonreturn valve (2), at least one connector (3) connected to the at least one inflatable envelope (4). The device also includes at least one separation wall (8), which compartmentalizes at least the end of at the connector (3) opening into at least two substantially hermetically independent inflatable envelopes (4).

A pierce pin for an inflator for piercing the frangible seal of a gas cartridge including in combination a shaft having a axial bore forming a tubular member having a tip with a rim and a pair of slots formed across the rim into the tip into the tubular member to an appreciable depth to form a tab, the tab being bent inwardly into the axial bore after formation of the slots.

A self-propelled personal flotation apparatus provides a motorized flotation board which includes internal water propulsion equipment and associated push-button controls. In use, a user straps the apparatus onto their chest area, enters a body of water such as a lake, a pond, or a pool, and is propelled across the water surface.
