A method of operating an inflation system is provided. The method includes recognizing that the inflation system is activated or actuated by a user, supplying current to an electromagnet of a solenoid valve of the inflation system such that an armature-valve element of the solenoid valve is moved to an open position, wherein movement of the armature valve element to the open position actuates an actuator housing that in turn causes a normally-closed valve element of a valve housing of the inflation system to open, and ceasing current supply to the electromagnet once the actuator housing is actuated.

A valve assembly is provided and includes a valve housing, an actuator housing coupled to the valve housing and configured when actuated to open a normally-closed valve element in the valve housing whereby pressurized fluid is permitted to flow through the valve housing and a solenoid valve. The solenoid valve includes an armature-valve element balanced to remain in a closed position and an electromagnet. The electromagnet generates magnetic flux that moves the armature-valve element into an open position such that at least a portion of the pressurized fluid flows into the actuator housing to actuate the actuator housing.

A personal survival system for use in water includes an inflatable chamber (9) and in inflation system (31) operable to inflate the inflatable chamber (9), wherein the inflation system (31) is mounted separately from and remotely from the inflatable chamber (9). Also disclosed are: a survival system for use in water includes an inflatable chamber including an inner layer and an outer layer, wherein the inner layer is separate from the outer layer; an inflation control system for use with an in-water survival system, the inflation control system comprises a selectively sealable chamber configured to contain water-triggered automatic inflation device of the survival system; and a personal survival system including an inflatable bladder and a moulded cover constructed from a flexible polymer.

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.

Described herein is a garment (e.g., pants, underpants, shorts, headgear, a skullcap, a glove, socks, shoes, a vest, a jacket, a shirt, an undershirt, an undergarment, or a full body suit) that can be worn by a wearer (e.g., military or civilian law enforcement personnel, an emergency first responder, or a dog) that includes inflatable bladders. When activated, the bladders of the garment inflate, thereby providing an increase in buoyancy to the wearer of the garment, e.g., while swimming.
