  • Publication number: 20240000347
    Abstract: Disclosed herein is a method, implemented in an automated drug delivery system for determining a risk of a hypoglycemic or hyperglycemic condition based on risk factors calculated each time a new blood glucose reading is received and providing an alert to the user should a risk be determined. The risk factors may include the current CGM reading, the trend of CGM readings, the amount of insulin-on-board of the user and the accuracy of previous alerts provided to the user. The method may be modified to provide the risk of hypoglycemia if the user were to engage in exercise or other physical activities.

  • Publication number: 20230420691
    Abstract: Disclosed is a method of manufacturing a cathode for a solid oxide fuel cell (SOFC) including preparing an electrode composition containing urea, ultrasonically spraying the electrode composition onto a GDC scaffold, and drying the scaffold. By using urea, calcination (?700° C.) after each infiltration cycle can be omitted, the next infiltration cycle is performed immediately after the drying (?100° C.), and thus the cathode manufacturing process time can be greatly reduced. Disclosed is also a solid oxide fuel cell including an anode support, an anode functional layer disposed on the anode support, an electrolyte disposed on the anode functional layer, and a cathode disposed on the electrolyte, wherein the cathode is formed by ultrasonic spraying using an electrode composition containing urea.

A count of a number of missing blood glucose measurement values over a period of time may be established. A controller may calculate a divergence of the number of missing blood glucose measurement values over the period of time from the average of missing blood glucose measurements over the predetermined time period. Based on a value of the divergence, a determination that a safety constraint for delivery of insulin is to be reduced. The safety constraint may be reduced by a predetermined percentage. An instruction to deliver an insulin dosage may be generated according to the reduced safety constraint may be forwarded to a wearable drug delivery device.

  • Publication number: 20230372613
    Abstract: The exemplary embodiments may employ a glucose prediction model (GPM) that is tailored to a user to account for insulin sensitivity or insulin insensitivity. The exemplary embodiments may predict future glucose levels based on past glucose levels for the user. Specifically, the GPM in exemplary embodiments may predict the future glucose level of the user as a weighted sum of most recent glucose level readings from the user. The exemplary embodiments may employ linear regression analysis to determine the values of the weights. These weights customize the GPM of the user based on the user's most recent glucose level history. Due to the customization, the GPM may more accurately predict future glucose levels of the user. As a result, the AID may exhibit better glucose level control for the user. The GPM of the exemplary embodiments may be updated on an ongoing basis.

  • Publication number: 20230377706
    Abstract: The exemplary embodiments may dynamically adjust an Insulin on Board (JOB) profile for a user of a medicament delivery system to customize the IOB profile to the user based on recent glucose level history and insulin deliveries rather than use the conventional static IOB profiles that are based on population averages. The exemplary embodiments may calculate a Duration of Insulin Action (DIA) for a user from the customized insulin decay curves. The exemplary embodiments may generate and send notifications to the user to help reduce the DIA of the user and/or to keep the DIA of the user from rising. The exemplary embodiments may aim to not overly constrain insulin delivery due to the contribution of insulin boluses to JOB.
