    Abstract: Embodiments of the present disclosure relate to approaches for transitioning a drug delivery device from a low-energy sleep state to a high-energy active state. In some embodiments, a system may include a drug delivery device, the drug delivery device including a pump mechanism coupled to a reservoir for expelling a liquid drug from the reservoir; and an activation component communicatively coupled to the pump mechanism. The activation component may include at least one of a sensor and a mechanical activation device, and a wake-up circuit operable to receive an input from the sensor or the mechanical activation device, wherein the input indicates a change in a device characteristic. Based on the change in the device characteristic, the wake-up circuit may be further operable to transition the drug delivery device from a low-energy state to an active state.

    Abstract: Disclosed are techniques to establish initial settings for an automatic insulin delivery device. An adjusted total daily insulin (TDI) factor usable to calculate a TDI dosage may be determined. The adjusted TDI factor may be a TDI per unit of a physical characteristic of the user (e.g., weight) times a reduction factor. The adjusted TDI factor may be compared to a maximum algorithm delivery threshold. Based on the comparison result, the application or algorithm may set a TDI dosage and output a control signal. Blood glucose measurement values may be collected from a sensor over a period of time. A level of glycated hemoglobin of the blood may be determined based on the obtained blood glucose measurement values. In response to the level of glycated hemoglobin, the set TDI dosage may be modified. A subsequent control signal including the modified TDI dosage may be output to actuate delivery of insulin.

    Abstract: Disclosed are devices, a system, methods and computer-readable medium products that provide techniques to implement functionality to determine when to softened upper bounds of drug delivery and how much to soften the upper bound. Future blood glucose measurement values may be predicted by calculating deviations between predicted blood glucose measurement values and additional blood glucose measurement values. A gain parameter may be determined for use with a model of predicting a user's blood glucose measurement values and determining future drug dosages. Safety constraints may be determined based on an evaluation of missing blood glucose measurement values. In addition, safety constraints may be determined based on an evaluation of a user's increased interaction with an automatic drug delivery device. A bolus uncertainty metric to determine an amount of insulin to be provided in a bolus dosage in response to a bolus request may be calculated.

    Abstract: A medicament delivery system, process and techniques are provided. The medicament delivery system may include a wearable medicament delivery device, a memory storing programming instructions, and a processor. The processor may be operable to execute the programming instructions, which cause the processor to receive an available medicament delivery history of a user, and determine whether the available medicament delivery history spans an extent of time greater than a first glucose history duration. The processor, in response to a determination that the extent of time spanned by the available medicament delivery history is greater than the first glucose history duration, determines an average daily medicament delivered. The processor calculates a trust value of the available medicament delivery history, and utilizes the trust value to determine a total daily medicament value of the user.

    Abstract: Disclosed are a system, methods and computer-readable medium products that provide safety constraints for an insulin-delivery management program. Various examples provide safety constraints for a control algorithm-based drug delivery system that provides automatic delivery of a drug based on sensor input. Glucose measurement values may be received at regular time intervals from a sensor. A processor may predict future glucose values based on prior glucose measurement values. The safety constraints assist in safe operation of the drug delivery system during various operational scenarios. In some examples, predicted future glucose values may be used to implement safety constraints that mitigate under-delivery or over-delivery of the drug while not overly burdening the user of the drug delivery system and without sacrificing performance of the drug delivery system. Other safety constraints are also disclosed.

    Abstract: A drug delivery system including a memory storing programming code operable to control delivery of a drug, a user interface operable to accept an input indicating a perceived glucose state of a user, and a processor operable to execute the programming code. When executed, the programming code causes the processor to: receive a perceived state signal from the user interface indicating the perceived glucose state of the user, evaluate the perceived glucose state of the user indicated by the perceived state signal using a glucose measurement value corresponding in time to when the perceived state signal was received, determine an adjustment to a drug delivery algorithm, and utilize the adjustment in a determination of a drug delivery dosage to be administered to a user.
