A modular, multi-crew life support system and a method of assembling the system involve a fan to draw in ambient air. The system includes one or more assemblies that produce conditioned air from the ambient air, and a housing to support an oxygen source. The system also includes a port configured as an inlet from the oxygen source to augment the conditioned air, and a duct to disperse a result of augmenting the conditioned air as output air to support two or more occupants of an enclosure.

A sterile body suit apparatus, system, and method is provided. In certain embodiments, the sterile body suit apparatus may comprise a helmet member, a lower extremity member, and a control interface means. The helmet member may comprise a respiratory means to provide uncontaminated, breathable air to a wearer, an ingestion means for drinking, eating, and vaping, and an audio communication means. The lower extremity may be defined by a torso, a first arm, and a second arm, and may further comprise an egestion means. Moreover, in some embodiments, the sterile body suit may further comprise a temperature control means and a tactile sensation means. The sterile body suit method may comprise the steps of: providing one or more mobile computing devices; providing one or more body suits at an environment having a local computing device; receiving, at the one or more mobile computing devices, a suit selection; generating and transmitting, at the one or more mobile computing devices, a suit selection notification; receiving, at the local computing device, the suit selection notification; and preparing and delivering, at the environment, the one or more body suits to one or more wearers.

A cough catching device is an apparatus used to limit the spread of airborne and droplet-transmissible pathogens by providing a sanitary tool to substantially capture a cough or sneeze. The cough catching device utilizes at least one membrane enclosing an internal cavity, wherein an aperture is formed into the membrane in fluid communication with the internal cavity. At least one flexible member is integrated into the membrane to bias the aperture closed over the internal cavity. The flexible member may be manually deformed by a user to expand the aperture, enabling a user to cough or sneeze into the internal cavity to capture any droplets with the membrane.

Disclosed is an adjustable support frame for a breathing apparatus having an adjustable longitudinal dimension and a user-facing side configured to substantially overlay a user's back in use, the adjustable support frame comprising: a first frame portion and a second frame portion, the first and second frame portions being moveable relative to each other so as to adjust the longitudinal dimension; an adjustment mechanism having a locked configuration which inhibits relative movement of the first and second frame portions and an unlocked configuration which permits relative movement of the first and second frame portions; wherein the adjustment mechanism comprises one or more actuating elements which are operable to actuate the adjustment mechanism from the locked configuration to the unlocked configuration, the one or more actuating elements being provided on a surface which is substantially perpendicular to the user-facing side of the support frame.

Apparatus and associated methods relate to a body-worn unitary harness having a shoulder portion and a waist portion in tensile communication with one another, such that both the shoulder and the waist portions can be simultaneously adjusted using a single adjustment mechanism to conform to a wearer's body. In an illustrative embodiment, a length of webbing may thread through an angle-turning buckle and change direction therein. Tensile forces in the length of webbing may be directed in different directions on either side of the angle-turning buckle. A single clasp may facilitate both donning and doffing of the unitary harness. An implement connector may be coupled to a hip member and configured to connect an implement to the unitary harness. Various exemplary unitary harnesses may provide comfortable implement carrying capacity while automatically adjusting relative waist and shoulder lengths to accommodate a user's movements and positions.
