Abstract: Various analyte sensing apparatuses and associated housings are provided. Some apparatuses comprise one or more caps. Some apparatuses comprise a two-part adhesive patch. Some apparatuses comprise one or more sensor bends configured to locate and/or hold a sensor in place during mounting. Some apparatuses utilize one or more dams and/or wells to retain epoxy for securing a sensor. Some apparatuses utilize a pocket and one or more adjacent areas and various transitions for preventing epoxy from wicking to undesired areas of the apparatus. Some apparatuses include heat-sealable thermoplastic elastomers for welding a cap to the apparatus. Related methods of fabricating such apparatuses and/or housings are also provided.

Abstract: Devices and methods for providing a user with alerts are provided. The alerts may take different forms, such as an output to a display, a speaker, a vibration module, a shock module, etc. The alerts provide the user with sufficient information to take appropriate action, but the devices may be of limited functionality to enhance their compactness, discreetness, wearability, etc., while also lowering their cost to manufacture.

Abstract: In some aspects, an apparatus for a biosensor includes a sensor wire and a rigid member. The rigid member may be coupled to the sensor wire and include a contact surface. The contact surface may be sized to enable a suction head of a robotic placement device to create a vacuum seal on the contact surface for lifting the sensor wire and rigid member.

Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: Systems and methods for processing sensor data and self-calibration are provided. In some embodiments, systems and methods are provided which are capable of calibrating a continuous analyte sensor based on an initial sensitivity, and then continuously performing self-calibration without using, or with reduced use of, reference measurements. In certain embodiments, a sensitivity of the analyte sensor is determined by applying an estimative algorithm that is a function of certain parameters. Also described herein are systems and methods for determining a property of an analyte sensor using a stimulus signal. The sensor property can be used to compensate sensor data for sensitivity drift, or determine another property associated with the sensor, such as temperature, sensor membrane damage, moisture ingress in sensor electronics, and scaling factors.

Abstract: Systems and methods for processing sensor analyte data are disclosed, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. The sensor can be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. Reference data resulting from benchtop testing an analyte sensor prior to its insertion can be used to provide initial calibration of the sensor data. Reference data from a short term continuous analyte sensor implanted in a user can be used to initially calibrate or update sensor data from a long term continuous analyte sensor.
