Abstract

In one embodiment, a method is provided. The method comprises: receiving, in a vehicle, at least one pollution parameter; and adjusting at least one fluid flow regulating mechanism position, to regulate an intake of pollutants into an environmental control system of the vehicle, based upon the at least one pollution parameter.

First claim

What is claimed is:

1. A fluid flow regulating system of a vehicle, the system comprising:
a ram duct configured to accept fluid flow into the vehicle;
a fluid flow regulating mechanism coupled to the ram duct and coupled to a processing system of the vehicle; and
at least one heat exchanger coupled to a cabin of the vehicle and the ram duct and configured to cool air flowing through the at least one heat exchanger using ram fluid flowing through the ram duct;
wherein the fluid flow regulating mechanism is controlled by the processing system of the vehicle to adjust a size of an opening of the ram duct to regulate the amount of ram fluid flowing through the ram duct based upon at least one pollution parameter.

2. The system of claim 1 , further comprising the processing system; and
at least one sensor, coupled to the processing system, comprising at least one of: at least one particle sensor, a global navigation satellite system receiver, an altimeter, a cabin temperature sensor, and an exterior temperature sensor.

3. The system of claim 2 , further comprising a communications system coupled to the processing system; and
wherein the communications system is configured to receive the at least one pollution parameter from an operations center.

4. The system of claim 1 , further comprising a compressor coupled to the at least one heat exchanger; and
a turbine coupled to the at least one heat exchanger.

5. The system of claim 1 , further comprising a ram fluid fan in the ram duct.

6. A method, comprising:
receiving, in a vehicle, at least one pollution parameter; and
adjusting, by at least one fluid flow regulating mechanism, a size of an intake opening based upon the at least one pollution parameter to regulate an amount of intake of pollutants into an environmental control system of the vehicle.

7. The method of claim 6 , wherein receiving, in the vehicle, the at least one pollution parameter comprises receiving, in the vehicle, the at least one pollution parameter from at least one of an operations center, and at least one particle sensor of the vehicle.

8. The method of claim 6 , further comprising determining commands for the intake of the pollutants into the environmental control system of the vehicle.

9. The method of claim 6 , further comprising determining if the at least one pollution parameter is qualified.

10. The method of claim 6 , further comprising receiving cabin temperature.

11. The method of claim 10 , further comprising determining if the cabin temperature is above a temperature threshold.

12. The method of claim 6 , further comprising receiving exterior temperature.

13. The method of claim 6 , receiving, in a vehicle, while the vehicle is stationary at least one pollution parameter from at least one of an operations center, or at least one particle sensor of the vehicle.

14. An operations center, comprising:
an operations center communications system;
an operations center processing system coupled to the operations center communications system;
wherein the operations center processing system is configured to generate at least one pollution parameter; and
wherein the operations center communications system is configured to communicate the at least one pollution parameter to a vehicle to prompt the vehicle to adjust a size of an intake opening to regulate the intake of pollutants into an environmental control system of the vehicle.

15. The operations center of claim 14 , wherein the at least one pollution parameter comprises at least one of: data related to pollution along a travel path of the vehicle, and
at least one command to regulate ram fluid flow to at least one heat exchanger in the vehicle.

16. The operations center of claim 14 , wherein the operations center processing system is configured to be coupled to at least one data source.

17. A method, comprising:
obtaining pollution data;
determining the location of a vehicle;
generating at least one pollution parameter; and
communicating, to the vehicle, at least one pollution parameter configured to adjust a size of an intake opening to do at least one of: regulate the intake of pollutants into the environmental control system of the vehicle, and alert an operator of the vehicle.

18. The method of claim 17 , wherein the at least one pollution parameter comprises at least one of data related to pollution, and at least one command.

19. The method of claim 17 , further comprising receiving a request for pollution data from the vehicle.

20. The method of claim 17 , further comprising determining if a vehicle is a subscriber.
