A breathing gas delivery system comprising a gas flow controller, at least one breathing apparatus, and at least one first length of tubing coupling the breathing apparatus to the gas flow controller. The gas flow controller has a body having an on/off switch, at least one gas input, at least one gas output, and at least one control mechanism for controlling flow of gas to the gas output. The breathing apparatus comprises a T-shaped gas input, a breathing bag coupled to the T-shaped gas input, a second length of tubing having two opposed ends, wherein one end is coupled to the other arm of the T-shaped gas input, a filter coupled the second length of tubing, and a nasal assembly coupled to the filter, the nasal assembly comprising a nasal hood, one or more straps, and an airtight elbow coupling for coupling the nasal hood to the filter.

The aircraft emergency oxygen supply system includes one or more sources of supplemental breathable oxygen, one or more inlet valves for one or more breathing devices, connected to the inlet valves, and one or more cabin air pressure transducers. A pressure controller controls the inlet valves in response to the one or more cabin air pressure transducers. One or more second pressure transducers may connected to conduits downstream of inlet valves to be monitored, and the pressure controller may also control operation of the inlet valves in response to the one or more second pressure transducers.

A connector system for connecting a cable having a length to an item includes a base operatively connectible to the item, the base including a channel to seat at least a portion of the cable, the channel being in operative connection with the item upon connection of the base to the item, and a rotatable member which is rotatable relative to the base. The cable is in operative connection with the rotatable member so that, as the rotating member rotates relative to the base, a bend in the cable is formed at different locations in the length of the cable such that the different locations define different lengths of the cable. The different lengths of the cable become positioned within the channel as the rotating member rotates relative to the base.
