Abstract: An air purifying respirator includes a dual stage fan that sucks outside air in through the filter canisters and then pushes the filtered air on to the user's mask or hood, where excess air escapes. A differential pressure sensor measures the pressure within the passages after the dual stage fan and in the ambient environment to estimate the user's rate of respiration. The microcontroller monitors the estimated rate of respiration, as well as the estimated altitude and its estimated amount of oxygen to calculate a user's filtered air flow need. The microcontroller adjusts the van via a fan controller to the appropriate air flow level. The microcontroller further monitors the battery level, filter life, and for low pressure within the user's mask and operates their respective indicators when problem levels arise. The battery supplies power to the microcontroller, power on/off button, and the dual stage fan.

The system provides a control base for coupling to one of a plurality of different cartridges containing product, at least two cartridges having different modalities of delivery—the coupled control base and selected cartridge providing a dosing device. Each cartridge has at least a unique identifier, which may be read by the control base and correlated through a database to confirm that the user is authorized to use the cartridge, and use of the cartridge for a dose of product will not conflict with other products received by the user and known to the system. Cartridges that are not coupled to the control base are non-functional and cannot dispense product as intended with the system. An associated method of use is also provided.

Abstract: An oxygen system supplies either 100% oxygen to a demand valve in a mask or pulses of oxygen to the mask. Switching is automatic during a parachute descent. The system includes a valve manifold that is responsive to ambient pressure such that at low pressures it is configured to deliver gas from either an oxygen cylinder or an aircraft supply line to the mask demand valve and at higher pressures it is configured to deliver gas from the cylinder to a pulse gas delivery system. The mask also includes an inhalation valve that is closed if oxygen is supplied to the demand valve. Otherwise, the inhalation valve opens to allow ambient air to be drawn in and the pulse gas delivery system delivers a pulse of oxygen in response to the onset of inhalation.
