Pneumatic delivery system with braking

1. A method to transport an object within a conduit extending between a first location and a second location, comprising:

generating a pneumatic force within the conduit by operating multiple pneumatic force devices at a location proximate the first or second location to move the object from the first location towards the second location;

detecting movement of the object within the conduit; and

based on the detected movement, controlling the pneumatic force from the same location by reversing the direction of the generated pneumatic force and altering the operation of the pneumatic force devices at the location in time-delayed increments to reduce the reversed pneumatic force over time and control movement of the object to a desired rate prior to arrival at the second location.

2. The method as recited in claim 1 , wherein generating the pneumatic force comprises activating a plurality of air blowers.

3. The method as recited in claim 2 , wherein controlling the pneumatic force comprises deactivating a first air blower of the plurality of air blowers.

4. The method as recited in claim 2 , wherein controlling the pneumatic force comprises activating a plurality of vacuum generators.

5. The method as recited in claim 1 , wherein controlling the pneumatic force is initiated upon detection of the object at a predetermined location within the conduit, wherein the predetermined location is between the first and second locations.

6. The method as recited in claim 1 , wherein the detected movement provides an indication of speed of the object, and wherein controlling the pneumatic force is based on the detected speed.

7. The method as recited in claim 1 , wherein controlling the pneumatic force is further based on a weight of the object.

8. A method of moving an object through a conduit extending between a first location and a second location, comprising:

generating a pneumatic pressure differential across the object within the conduit by operating multiple pneumatic force devices at a location proximate the first or second location to move the object from the first location to the second location; and

while the object is moving within the conduit, controlling the pneumatic pressure differential from the same location by reversing the direction of the generated pneumatic pressure differential and altering the operation of the pneumatic force devices at the location in time-delayed increments to reduce the reversed pressure differential across the object over time based on a weight of the object to stop the movement of the object at the second location.

9. The method as recited in claim 8 , wherein generating the pneumatic pressure differential comprises increasing the pressure at the first location relative to the second location.

10. The method as recited in claim 8 , wherein generating the pneumatic pressure differential comprises reducing the pressure at the first location relative to the second location.

11. The method as recited in claim 8 , further comprising:

detecting movement of the object within the conduit; and

determining the weight of the object based on the detected movement.

12. The method as recited in claim 8 , further comprising:

detecting the object within the conduit; and

reducing the reversed pressure differential across the object over time controls movement of the object to a desired rate.

13. The method as recited in claim 12 , wherein the revers pressure differential is reduced incrementally.

14. The method as recited in claim 13 , wherein generating the pressure differential comprises activating a plurality of air blowers located proximate the first location; and wherein altering the operation in increments comprises sequentially deactivating the air blowers.

15. The method as recited in claim 13 , wherein generating the pressure differential comprises activating a plurality of pneumatic force devices proximate the first location; and wherein altering the operation in increments comprises sequentially deactivating the pneumatic force devices to stop the object at the second location.

16. A pneumatic transport system for transporting an object, comprising:

a pressure differential system configured to generate a pressure differential across the object within a conduit extending between a first location and a second location with the operation of multiple pneumatic force devices proximate the first or second location;

sensors to detect movement of an object through the conduit between the first location and the second location; and

a control system in communication with the pressure differential system and the sensors to control the pressure differential within the conduit based on the detected movement of object, wherein the control system is configured to reverse the direction of the generated pressure differential and alter the operation of the multiple pneumatic force devices in time-delayed increments to reduce the reversed pressure differential across the object over time to slow movement of the object to a desired rate prior to arrival at the second location.

17. The system as recited in claim 16 , wherein the pressure differential system comprises a plurality of air blowers and a plurality of vacuum generators.

18. The system as recited in claim 17 , wherein the pressure differential system is located proximate the first location.

19. The system as recited in claim 17 , wherein the pressure differential system is a distributed system, wherein a first portion of the distributed system is located proximate the first location and a second portion of the distributed system is located proximate the second location.

20. The system as recited in claim 17 , wherein the control system is capable of incrementally reducing the reversed pressure differential within the conduit based on the detected movement of the object.

21. The system as recited in claim 20 , wherein the control system is capable of incrementally reducing the reversed pressure differential within the conduit further based on a weight of the object.
