[0058] System Architecture:

[0059] Referring next to FIG. 5 there is shown a sample architecture of a system 50 in accordance with the present invention. A plurality of refrigerators 1 in accordance with the present invention are shown, in addition to a server 15. A plurality of user client devices 22 are also shown. The user client devices 22 would be any type of a device capable of communication and interaction with the server 15 for the formulation and transmission of zone opening requests. The wide area network 23, specifically likely the Internet, connecting the server 15, and the zone opening controllers 8 of each refrigerator 1 as well as the plurality of user client devices 22 are also shown.

[0060] The system 50 permits the actuation of locks and doors on multiple refrigerated storage zones 3 in multiple refrigerators 1 in accordance with the present invention.

[0061] A user, using a user client device 22 can initiate a communication session with the server 15 by the network 23, for the purpose of transmitting a zone opening request to the server in accordance with the remainder of the method. The server 15 and the software component 18 in combination with the data structures and the remainder of the software resident there and will permit the remotely triggered actuation or opening of the locks on individual refrigerated storage zones 3 within a refrigerator in accordance with the present invention.

[0062] Method Overview:

[0063] Referring next to FIG. 6 there is shown a flowchart demonstrating the steps in one embodiment of a method in accordance with the present invention. This would be a method in accordance with the use of the system of FIG. 5. The flowchart of this Figure shows a single zone opening data transaction. It will be understood that typically in a client/server method such as is contemplated in the control system outlined herein, the software would actually facilitate these types of transactions in a repeated or looped basis and that will be understood to those skilled in the art of software design and is obviously intended to be encompassed within the scope of the present invention.

[0064] The zone database 21 would be pre-populated with zone records and affiliated user credentials as required.

[0065] A user wishing to access their affiliated refrigerated storage zone 3 would initiate a communication session between their user client device 22 and the server 15. The server, as shown at step 6-1, can serve an interface or communicate with the local application at the user client device 22 for the purpose of communication including formulating or receiving zone opening requests.

[0066] Via a browser interface, local application or otherwise, the user by other user client device 22 would transmit a zone opening request to the server 15 where it would be received. Receipt of the zone opening request at the server 15 is shown at step 6-2.

[0067] As outlined throughout, the zone opening request would be a data packet including at least information corresponding to a zone address 7 of a requested refrigerated storage zone 3 to be opened as well as user identification credentials. On receipt of a zone opening request at the server 15, the server software component 18 would authenticate the request by attempting to match it against zone records in the zone database 21. If the zone address indication as well as the user identification credentials provided in the zone opening request match a zone record in the zone database 21, the zone opening request is an accepted zone opening request. Authentication and acceptance of the zone opening request is shown at step 6-3. As shown, if the zone opening request received is not authenticated, the software component 18 can continue its listing loop for other zone opening requests to be received etc.

[0068] When a zone opening request is accepted, the server will open the corresponding storage zone. This will be done by the server 15 initiating a transmission of a zone opening instruction to the zone opening controller 8 corresponding to and connected by the local control bus to the lock 5 of the refrigerated storage zone 3 to be opened. Transmission of the zone opening instruction is shown at step 6-4.

[0069] On receipt of a zone opening instruction, the corresponding zone opening controller will parse the information contained in that instruction or data packet and trigger the opening of the corresponding lock 5 and/or 4 by a control signal on the local control bus 6.

[0070] It will be apparent to those of skill in the art that by routine modification the present invention can be optimized for use in a wide range of conditions and application. It will also be obvious to those of skill in the art that there are various ways and designs with which to produce the apparatus and methods of the present invention. The illustrated embodiments are therefore not intended to limit the scope of the invention, but to provide examples of the apparatus and method to enable those of skill in the art to appreciate the inventive concept.

[0071] Those skilled in the art will recognize that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the scope of the appended claims.
