Measure	Artificial Pancreas Control Type 1 Diabetes Mellitus subjects who fit the inclusion/exclusion criteria will undergo artificial pancreas closed-loop study for 28 hours. For the entire study, the adaptive component of Artificial Pancreas Control Software will be used to control the subject's blood glucose. Artificial Pancreas Control Software: This master controller software is used in conjunction with two subcutaneous continuous glucose monitoring systems and two Omnipod pumps, one for administering aspart insulin (NovoLog) and one for administering glucagon (GlucaGen), to control blood glucose levels. The insulin and glucagon infusion rates are determined by an automated version of the Adaptive Proportional Derivative (APD) insulin and glucagon control algorithm.

Mean Percent of Time in Target Blood Glucose Range	62.4 percentage of time Standard Deviation 7.0

SECONDARY outcome

Timeframe: all 28 hour studies

Mean difference of venous blood glucose from glucose target. Daytime venous blood glucose values (7am-11pm) subtracted from daytime target of 115 mg/dl. Nighttime venous blood glucose values (11pm-7am) subtracted from nighttime target of 140 mg/dl. This is a metric of how successful the closed loop algorithm was at controlling glucose.
