1. A method for diabetes management, the method comprising:

  • controlling insulin delivery to a host, using a processor comprising a controller module, the processor processing data collected from a continuous glucose sensor using in part a Kalman filter;

    iteratively evaluating internally derived data relative to a predetermined glucose boundary, wherein the internally derived data comprises processed glucose data and a learned insulin sensitivity of the host;

    adaptively adjusting the glucose boundary; and

    selectively turning the controller on or off, or controlling a rate of insulin delivery, responsive to the iterative evaluation, wherein the selectively turning the controller on or off, or the controlling the rate of insulin delivery, comprises selectively turning insulin delivery on or off or controlling the rate of insulin delivery when the processed glucose sensor data meets one or more predetermined criteria relative to the predetermined glucose boundary.
