Abstract: A mechanism is provided for managing the referencing of at least two versions of a function. A first version is a single threaded version that does not ensure multi-thread safety. A second version is a multi threaded version that does ensure multi-thread safety. The mechanism determines whether a set of executable code (e.g. a program) is currently executing in single-threaded mode or multi-threaded mode. If the executable code is executing in single-threaded mode, then the mechanism causes the executable code to reference the first version of the function. If the executable code is executing in multi-threaded mode, then the mechanism causes the executable code to reference the second version of the function. By doing so, the mechanism ensures that the additional overhead of ensuring multi-thread safety is incurred only when it is needed. In this manner, the mechanism makes execution of the function more optimal.

Abstract: A system for implementing a wide-range of glycemic control protocols (e.g., Tight Glycemic Control protocols) in an automated, semi-closed or closed loop manner thereby eliminating common sources of system error is provided herein. More specifically, the system can include a blood glucose measuring device in communication with a wide-range of databases and/or interfaces thereby allowing for typically independent steps such as patient testing, result determination, protocol adjustment (suggestions as well as actual calculations of new dosages), meal information, scheduling of future testing in light of test results, and administration of medicine to be performed automatically in a semi-closed or closed loop manner. Furthermore, the system provides for ultimate flexibility by allowing a protocol administrator to continuously add, subtract, and/or modify various steps of the protocol while maintaining the integrity and safety of the system.
