<qa>  What is the name of the two systems that are used to enhance the closed-loop systemSeveral groups around the world investigate efforts in developing closed-loop systems. Investigators combined two closed-loop systems with different mode of operation in order to enhance the closed-loop system. The two systems are Hybrid closed-loop system and the MD-Logic closed-loop system . The combined algorithm Hybrid logic closed loop HLCL was tested In silico and was proved to be safe and effective. The next step is to test the system in a clinical study in a supervised environment in a camp.
