Disclosed are apparatus and methodology subject matters for temperature monitoring and controlled access to refrigerated medications. An electronically controlled lock is installed on a refrigerator used for storage of temperature sensitive medications. Lock access is given to individuals having differing levels of access authorization so that user level authorization holders may have access to stored medications. Supervisor level authorization holders may have access to stored medications and may also effect changes in lock settings including setting alarm levels. Alarm levels may be adjusted to monitor temperatures within the refrigerated storage area so that in the case that temperature fall outside preset limits, access to the stored medicines may be had only by those individuals having supervisory access authorization.

1. A refrigerated area access control system, comprising: an access control circuit;a lock configured to be unlocked by said access control circuit;a user interface configured to provide user access to said access control circuit; anda temperature transducer coupled to said access control circuit and configured for placement within the refrigerated area;wherein said access control circuit is configured to monitor the temperature within the refrigerated area and to respectively permit differentiated access to the refrigerated area by a first user having a first access level and a second user having a second access level, such that a first user is denied access to the refrigerated area when the temperature within the refrigerated area is not maintained within predetermined parameters. 2. A refrigerated area access control system as in claim 1, wherein said user interface is further configured to permit said second user to adjust system operational parameters comprising one or more of adding credentials for first users, deleting credentials for first users, and adjusting temperature based parameter settings. 3. A refrigerated area access control system as in claim 2, further comprising a user readable display configured to display values representative of the temperature within the refrigerated area; andwherein said user interface comprises a control panel configured to permit manual programming of operational characteristics of the access control circuit by observation of said user readable display. 4. A refrigerated area access control system as in claim 1, further comprising: a computer interface associated with said user interface; anda computer; andwherein said computer is configured to permit said second user to adjust system operational parameters comprising one or more of adding credentials for first users, deleting credentials for first users, and adjusting temperature based parameter settings. 5. A refrigerated area access control system as in claim 1, wherein said lock comprises a motorized slam bolt latch. 6. A refrigerated area access control system as in claim 1, further comprising an alarm configured to be activated when the temperature within the refrigerated area is not maintained with said predetermined parameters. 7. A refrigerated area access control system as in claim 1, further comprising: a memory associated with said access control circuit; andwherein said access control circuit is configured to store in said memory a number of different valid credentials to be used to access said refrigerated area, an audit trail for each access to said refrigerated area, and data logging at predetermined time periods of temperature readings within said refrigerated area. 8. A refrigerated area access control system as in claim 7, further comprising a credential presentation device consisting of at least one of a key pad, an electronic card reader, a biometrics reader, and a computer interface. 9. A refrigerated area access control system as in claim 7, further comprising: a computer interface associated with said user interface; anda computer; andwherein said computer is configured to upload system operational parameters to said access control circuit and to download and display audit trails and logged temperature data. 10. A refrigerated area access control system as in claim 1, wherein: said refrigerated area comprises a refrigerator; andsaid access control system is configured to be retrofittable to said refrigerator. 11. A refrigerated area access control system as in claim 1, further comprising: a temperature modulator associated with said temperature transducer; andwherein said temperature modulator is configured to provide thermal shock protection for said thermal transducer. 12. A refrigerated area access control system as in claim 1, further comprising: a temperature modulator associated with said temperature transducer; andwherein said temperature modulator is configured as a thermal shock absorber to allow said thermal transducer to more accurately reflect the temperature of any materials stored in the refrigerated area. 13. A method of providing access to a refrigerated area, comprising: providing an access control circuit;monitoring temperature variations within the refrigerated area, for maintenance of such temperature variations within selected predetermined parameters;providing respectively differentiated access to the refrigerated area to a first user having a first credential enabled access level and to a second user having a second credential enabled access level; anddenying access to the refrigerated area by a first user if the temperature within the refrigerated area is not maintained within the selected predetermined parameters. 14. A method as in claim 13, further comprising: providing a user interface including a display and a control panel; andpermitting the second user to add first user credentials, delete first user credentials, and adjust temperature based parameters. 15. A method as in claim 14, further comprising: providing an alarm signal when the temperature within the refrigerated area is not maintained within the selected predetermined parameters for a predetermined period. 16. A method as in claim 13, wherein providing second user access comprises: providing a user interface including a computer interface;associating a memory with the access control circuit;storing temperature measurement data in the memory; andproviding a computer configured to permit the second user to upload data to the memory to add first user credentials, delete first user credentials, and adjust temperature based parameters, and to download and display stored data. 17. A method as in claim 16, further comprising: monitoring access events by first and second users; andstoring an audit trail of the access events in the memory. 18. A method as in claim 13, wherein the step of providing an access control circuit includes retrofitting such access control circuit to an existing refrigerated area. 19. A method as in claim 13, wherein the step of providing an access control circuit includes originally outfitting a refrigerated area with such access control circuit.
