Abstract
A system for detecting and alleviating pilot hypoxia is provided. The system includes an oxygen generator adapted to be powered by a power supply. The oxygen generator is in communication an oxygen delivery device where the oxygen delivery device is adapted to deliver supplemental oxygen to a pilot. A control module is in communication with the oxygen generator and the power supply. A hypoxia detection device is in communication with the control module wherein the control module causes one or both of the oxygen generator and the oxygen delivery device to increase an amount of oxygen being delivered to the pilot upon detection of pilot hypoxia. The hypoxia detection device may include a pupillometer and a luminometer and/or a flash generator.

A system for detecting and alleviating reduced cognitive function of a pilot, the system comprising:
- a) an oxygen supply system adapted to be actuated by a power supply, the oxygen supply system in communication with an oxygen delivery device, the oxygen delivery device adapted to deliver supplemental oxygen to a pilot,
- b) a control module in communication with the oxygen supply system and the power supply;
- and
- c) a reduced cognitive function detection device comprising a pupillometer configured to monitor a pupil size of the pilot, the reduced cognitive function detection device in communication with the control module wherein the control module includes a data file containing compiled pilot pupil size data as a function of ambient light and wherein the reduced cognitive function detection device further comprises a luminometer configured to measure an ambient light level wherein pilot pupil size is compared to the data file at the ambient light level so that a pupil size outside the pilot pupil size data indicates reduced cognitive function and wherein the control module causes one or both of the oxygen supply system and the oxygen delivery device to increase an amount of oxygen being delivered to the pilot upon detection of pilot reduced cognitive function.
A method for detecting and alleviating reduced cognitive function of a pilot, comprising:
- a) providing a system for detecting and alleviating reduced cognitive function of a pilot comprising:
- i) an oxygen supply system adapted to be actuated by a power supply, the oxygen supply system in communication with an oxygen delivery device, the oxygen delivery device adapted to deliver supplemental oxygen to a pilot,
- ii) a control module in communication with the oxygen supply system and the power supply;
- and
- iii) a reduced cognitive function detection device comprising a pupillometer configured to monitor a pupil size of the pilot, the reduced cognitive function detection device in communication with the control module wherein the control module includes a data file containing compiled pilot pupil size data as a function of ambient light and wherein the reduced cognitive function detection device further comprises a luminometer configured to measure an ambient light level;
- b) monitoring the pupil size of the pilot using the pupillometer;
- c) measuring the ambient light level using the luminometer;
- d) comparing the monitored pupil size to the compiled pilot pupil size data corresponding to the measured ambient light level to detect an occurrence of reduced cognitive function;
- e) communicating via the reduced function detection device a pupillometer control signal to the control module upon the occurrence of reduced cognitive function of the pilot;
- and
- f) communicating via the control module a control module control signal to one or both of the oxygen delivery device and oxygen supply system to increase the oxygen being delivered to the pilot.
