Abstract
This invention provides oxygen-enriched air to the passenger compartment of wheeled vehicles to reduce drowsiness of drivers of wheeled vehicles so as to reduce the number of accidents caused by drowsy drivers. The invention also makes drivers and passengers in wheeled vehicles more alert and feel better by increasing the percentage of oxygen in the passenger compartments of wheeled vehicles to a beneficial and safe level.
Claims15
In a wheeled vehicle having a passenger compartment, the improvement comprising a system for supplying oxygen-enriched air to said passenger compartment for helping drivers and passengers remain alert and maintain well-being including drowsiness reduction, said system comprising:
- means for producing oxygen-enriched air;
- a conduit for flowing said oxygen-enriched air into said passenger compartment;
- an oxygen concentration detection device for detecting the oxygen content of air in said passenger compartment;
- and
- means for limiting the oxygen concentration of the air in said passenger compartment so as to not exceed a safe level.
A system for supplying oxygen enriched air to a passenger compartment in a wheeled vehicle for helping drivers and passengers remain alert and maintain well-being including drowsiness reduction, comprising:
- at least one gas separation membrane for producing oxygen-enriched air;
- a compressor for supplying compressed ambient air to said at least one membrane;
- a conduit for flowing said oxygen-enriched air from said membrane into said passenger compartment;
- an oxygen concentration measuring device for measuring the oxygen content of air in said passenger compartment;
- and
- means for limiting the oxygen content of the air in said compartment so as to not exceed a preselected safe concentration.
A system for supplying oxygen-enriched air to a passenger compartment in a wheeled vehicle for helping drivers and passengers remain alert and maintain well-being including drowsiness reduction, comprising:
- means for producing oxygen-enriched air having an oxygen content not exceeding a reasonably safe concentration;
- and
- means for flowing said oxygen-enriched air into a passenger compartment of a wheeled vehicle at a flow rate sufficient to raise the oxygen concentration of the air in said compartment to about 24-25% in less than about 10-20 minutes.
