Abstract: Methods, systems, and devices for experimental programs are described. A method includes acquiring baseline PPG data from a user via a wearable device throughout a time interval, and displaying one or more experimental programs via a user device based on the baseline PPG data, where each experimental program is associated with one or more behavioral changes. Upon a selection of an experimental program, the method includes acquiring additional PPG data from the user via the wearable device throughout a time interval of the experimental program. The method includes identifying adherence of the user to a behavioral change of the experimental program based on the additional PPG data and/or information received via the user device. The method further includes displaying, via the user device, changes between the baseline PPG data and the additional PPG data based on identifying the adherence to the behavioral change.

Abstract: Apparatuses and methods for transitioning to sleep mode or otherwise modified glucose target range in automated insulin delivery systems. For example, sleep mode can include a lower glucose target and/or lower and narrower glucose target range because of fewer variables that affect glucose values during sleep such as eating and exercise. Due to increased stability provided by the sleep mode target range, it is desirable to transition to the sleep mode target range as quickly as possible, while ensuring the transition is done safely and does not risk low glucose or hypoglycemia by too quickly switching to the lower and narrower target range. Systems and methods disclosed herein therefore provide various approaches for safely and quickly transitioning to sleep mode or other modified target ranges in order to improve time in range by being more aggressive to get to the lower sleep mode or other target faster without risking hypoglycemia.

Rotation of at least a portion of the arm drives at least a portion of the arm radially outward from an axis of the downhole tool.

Abstract: A system for driving an arm radially outward from a work string axis includes a pivot block coupled to the arm at a first coupling, the arm rotating about the first coupling in a first direction to move from a stored position to an expanded position, and about the first coupling in a second direction to move from the expanded position to the stored position. The system also includes a biasing member that drives movement of the arm in the first direction. The system further includes a chamber for storing the biasing member within a pivot block diameter when the arm is in the stored position.

Abstract: A method for providing on-demand service information for aerial surveys is provided. An application based software platform is created to form a medium for both customers and pilots to complete aerial survey requests. The application based software platform allows customers to post survey requests for pilots to view. If interested, pilots are able to compete for the survey requests. The interested pilots are then selected based upon the pilot criteria. The application based software platform creates a flight plan to conduct the survey. This flight plan is transmitted to the selected pilot and a drone, owned by the pilot, is dispatched to collect the raw data. Once collected, the raw data is received and processed by the computing system to create the survey. The survey is distributed to the customer, and the payment is distributed to the pilot. The survey is also stored in the database of surveys.
