Abstract: The exemplary embodiments attempt to identify impending hypoglycemia and/or hyperglycemia and take measures to prevent the hypoglycemia or hyperglycemia. Exemplary embodiments may provide a drug delivery system for delivering insulin and glucagon as needed by a user of the drug delivery system. The drug delivery system may deploy a control system that controls the automated delivery of insulin and glucagon to a patient by the drug delivery system. The control system seeks among other goals to avoid the user experiencing hypoglycemia or hyperglycemia. The control system may employ a clinical decision support algorithm as is described below to control delivery of insulin and glucagon to reduce the risk of hypoglycemia or hyperglycemia and to provide alerts to the user when needed. The control system assesses whether the drug delivery system can respond enough to avoid hypoglycemia or hyperglycemia and generates alerts when manual action is needed to avoid hypoglycemia or hyperglycemia.

Abstract: A device and method for moving a turf roll end first through a narrow gate. A turf roll mover has a front cradle and a rear cradle, connectable by a connector bar. The connector bar is used to lever the turf roll onto the turf roll mover and to connect the front and rear cradles. Each cradle has four wheels and tires suited for driving over the ground with relatively low friction. To move the turf roll onto the mover, the connector bar is inserted into the one end of the turf roll and used as a lever to lift that end onto the front cradle, then inserted into the other end of the turf roll to lift that end onto the rear cradle. The connector bar is placed into a receiver on the front cradle and into a receiver on the rear cradle to connect the cradles.

Abstract: In one example, a laser assembly may include a substrate, a lens array, and a laser array. The lens array may be positioned on a first side of the substrate. The laser array may be positioned on a second side of the substrate opposite the first side. Lasers of the laser array may be oriented to generate optical signals through the substrate to corresponding lenses of the lens array. The lens array may include at least one concave lens and at least one convex lens. The concave and convex lenses may map the irradiance of the lasers to a common target irradiance profile, resulting in an alignment tolerant laser assembly.

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.

The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors, or in response to an infrared or radio-frequency remote control.

Abstract: Exemplary embodiments provide an approach to predicting meal and/or exercise events for an insulin delivery system that otherwise does not otherwise identify such events. The insulin delivery system may use a model of glucose insulin interactions that projects estimated future glucose values based on a history of glucose values and insulin deliveries for a user. The predictions of meal events and/or exercise events may be based on residuals between actual glucose values and predicted glucose values. The exemplary embodiments may calculate a rate of change of the residuals over a period of time and compare the rate of change to thresholds to determine whether there likely has been a meal event or an exercise event. The insulin delivery system may then take measures to account for the meal event or the exercise event by the user.

Abstract: Compensation may be provided for the varying accuracy levels of a sensor over time. As a result of the compensation, the medicament delivery device may perform better. The sensor may provide input to a medicament delivery device, and the input may be used to determine a dose of medicament to be delivered to a user by the medicament delivery device. A degree of inaccuracy of sensor values may be determined based on when in the lifetime a sensor value is generated. Glucose level values read by a glucose monitor, such as a CGM, may be directly modified before being used by an automated insulin delivery (AID) control of an insulin delivery device. The compensation for the inaccuracy of the glucose level values from the glucose monitor instead may be achieved by modifying a weight coefficient of a glucose cost component of a cost function in one example.

Abstract: Disclosed are a device, a computer-readable medium, and techniques that provide an onboarding process and an adaptivity process for a drug delivery device. A processor executing an onboarding process determines whether a history of delivered insulin to a user meets certain sufficiency requirements. The onboarding process enables a processor to cause the drug delivery device to administer doses of insulin to a user according to an initial total daily insulin dose calculation that is determined based on the sufficiency of the insulin delivery history. The initial total daily insulin may be adapted according to the adaptivity process as new insulin delivery is collected. The insulin delivery history, when sufficient, may be used to set total daily insulin dosages that enable automated insulin delivery upon replacement of a drug delivery device. The adaptivity process may be implemented to modify an initial insulin delivery doses to provide adapted insulin delivery doses.

Abstract: The exemplary embodiments provide medicament delivery devices that use cost functions in their control systems to determine medicament dosages. The cost function may have a medicament cost component and a performance cost component. The exemplary embodiments may use cost functions having medicament cost components that scale asymmetrically for different ranges of inputs (i.e., different candidate medicament dosages). The variance in scaling for different input ranges provides added flexibility to tailor the medicament cost component to the user and thus provide better management of medicament delivery to the user and better conformance to a performance target. The exemplary embodiments may use a cost function that has a medicament cost component (such as an insulin cost component) of zero for candidate dosages for a range of candidate dosages (e.g., below a reference dosage).
