Methods, apparatuses, and systems for mechanically releasing a predetermined amount of supplemental oxygen to a user via a mechanical initiator are disclosed with the release of the amount of supplemental oxygen based on and in response to the combined factors of a user's determined oxygen consumption based on sensing a user's inhalation combined with determining the ambient pressure in the area of the user.

Apparatus, system, and method for pressure altitude-compensating breath-controlled oxygen release

The present disclosure provides a door latch assembly including (a) a locking pin movable from an extended position where the locking pin is positioned in an aperture of a driver, to a retracted position where the locking pin is configured to be removed from the aperture of the driver, (b) a solenoid including a solenoid plunger having a first end coupled to the locking pin and a second end coupled to a shaft, (c) a lever arm having a first end engaging the shaft, and (d) a switch including an actuator button in contact with the lever arm, wherein when the solenoid is actuated the solenoid plunger moves to retract the locking pin from the aperture and causes the shaft to displace the lever arm and the actuator button to activate the switch.
