Abstract

An automated cafeteria. Customers place orders via computers, over the Internet. Their orders are prepared by the cafeteria, and placed into a delivery bay. Each customer retrieves his own order from the bay, and carries it to a payment station. Security measures discourage theft.

Claims

1. An automated cafeteria system comprising:

a cafeteria web site for presenting a menu over a public-access network and for assigning an order number to an order comprised of menu selections;

a computer for viewing the menu presented by the cafeteria web site over the public-access network, for issuing an order message comprised of menu selections, and for receiving the assigned order number;

a storage unit coupled to the computer for storing the assigned order number;

a label generator for receiving the assigned order number from the cafeteria web site and for generating a label identifying the assigned order number for a corresponding prepared order, the label being associated with the corresponding prepared order; and

an automated check-out station for retrieving the assigned order number from the storage unit and for verifying that the retrieved assigned order number corresponds to the assigned order number on the generated label for a prepared order presented to the automated checkout station so that the prepared order may be obtained at the automated check-out counter.

2. The system of claim 1 wherein the computer is a personal digital assistant (PDA) and the storage unit for the assigned order number is internal to the PDA.

3. The system of claim 1 further comprising:

a card reader coupled to the computer; and

the storage unit is a stored-value card so that an assigned order number received by the computer from the cafeteria web site may be stored by the card reader in the stored-value card and retrieved from the stored-value card by the automated check-out station.

4. The system of claim 3 wherein the automated check-out station deducts an amount corresponding to the prepared order that is verified as having an assigned order number on its generated label that corresponds to the assigned order number retrieved from the stored-value card.

5. The system of claim 1 further comprising:

a basket for holding a prepared order, the basket having a sensor for detecting removal of a prepared order placed within the basket and generating an alarm in response to detection of such removal; and

the automated check-out station for deactivating the basket sensor so that the prepared order may be removed from the basket without generating the alarm in response to the detection of such removal.

6. The system of claim 1, further comprising:

a basket for holding a prepared order;

an anti-theft device coupled to the basket; and

a detector for detecting unauthorized removal of the basket from the automated check-out station site so that the anti-theft device has to be de-activated in order for the basket to be removed from the automated check-out station site without generating an alarm.

7. A method for automating cafeteria order correlation comprising:

presenting a menu over a public-access network;

selecting menu items from the presented menu over the public-access network to comprise an order;

assigning an order number to the order comprised of the selected menu items;

receiving the assigned order number over the public-access network;

storing the assigned order number received over the public-access network in a storage unit;

generating a label identifying the assigned order number for a corresponding prepared order comprised of selected menu items;

retrieving the stored assigned order number from the storage unit at an automated check-out station site where prepared orders having generated labels are located; and

verifying that the stored assigned order number retrieved at the site corresponds to the generated label identifying the assigned order number for a prepared order so the prepared order may be obtained contemporaneously with the assigned order number verification.

8. The method of claim 7 wherein the assigned order number storage comprises storing the assigned order number in a personal digital assistant (PDA);

and the assigned order number verification further comprising;

retrieving the assigned order number from the PDA and determining whether the retrieved assigned order number corresponds to the generated label identifying the assigned order number.

9. The method of claim 7, the storing of the assigned order number further comprising:

storing the assigned order number received over the public-access network in a stored-value card so that the assigned order number may be retrieved from the stored-value card at the site where prepared orders having generated labels are located for verification.

10. The method of claim 7, the method further comprising:

deducting an amount corresponding to the prepared order verified as having an assigned order number on its generated label that corresponds to the assigned order number retrieved from the stored-value card.

11. The method of claim 7 further comprising:

detecting removal of a prepared order from a basket containing the prepared order before order identification verification occurs; and

deactivating the removal detection so that the prepared order may be removed from the basket without detection.

12. The method of claim 7, the method further comprising:

an anti-theft device to a basket containing a prepared order;

detecting unauthorized removal of the basket containing the prepared order from the automated check-out station site; and

deactivating the anti theft device in response to the verification that the stored assigned order number corresponds to the assigned order number for the prepared order in the basket.
