Abstract

The presented inventions seek to create a verifiable and closed loop chain-of-custody for a specific transaction in a pneumatic tube transport system while allowing a sender and recipient to perform asynchronous activity. That is, one aspect the presented inventions allows a sender to securely send a carrier to a desired recipient while allowing the desired recipient to receive the secured carrier at a convenient time and/or location without tying up system resources. Another aspect improves the physical barriers between high value payloads and the unintended recipients. This is done in part by introducing randomness into the carrier delivery process such that no member of the general public or facility staff knows the location and/or delivery time of a secured carrier without having access to specific database records indicating the current location and/or delivery status of the secured carrier.

Claims

1. A method for use in a computerized controller for operating a pneumatic carrier system that includes a plurality of user stations, pneumatic tubes and transfer devices, comprising:

receiving a secured carrier transaction request from a sending user for a carrier to be dispatched from an originating user station;

generating control signals to move the carrier from the originating user station to an intermediate storage location within the pneumatic carrier system;

receiving an input from the sending user identifying a receiving user who is a desired recipient of the carrier;

sending a message to a user communication device associated with the receiving user;

maintaining the carrier within the pneumatic carrier system while awaiting a response signal from the receiving user;

receiving the response signal from the receiving user, where the response signal indicates the receiving user is available to receive the carrier; and

based on the response signal generating control signals to effect delivery of the carrier, via the pneumatic system, to a destination location associated with the receiving user.

2. The method of claim 1, further comprising;

recording a carrier identifier of said carrier in a transaction record; and

prior to delivery, reading a carrier identifier to confirm the carrier is the carrier associated with the secured carrier transaction request.

3. The method of claim 1, wherein said destination location is a user station identified in the secured carrier transaction request.

4. The method of claim 3, wherein the destination location is a user station identified in the response signal.

5. The method of claim 1, further comprising:

upon receiving the response signal, generating an access code; and

delivering the access code to the user communication device.

6. The method of claim 5, further comprising:

generating control signals to effect movement of the carrier to a user station at the destination location; and

upon receiving the access code input into a user interface at the user station, generating a signal to effect release of the carrier.

7. The method of claim 1, wherein sending a message comprises generating a message indicating a carrier is intended for delivery to a specified recipient.

8. The method of claim 1, wherein sending said message comprises sending a message via a telephonic network.

9. The method of claim 1, wherein sending said message comprises sending a message via a computer network.

10. The method of claim 1, further comprising:

accessing a database to identify the user communication device associated with the intended destination.

11. The method of claim 1, wherein sending the message further comprises

generating an access code, wherein the access code is sent with the message.

12. The method of claim 11, further comprising:

receiving the access code as entered into an input device at the destination location; and

releasing the carrier to the destination location.

13. The method of claim 12, further comprising:

sending a delivery confirmation message to one of;

a display device of the originating user station; and

a user communication device associated with the originating user station.
