Abstract: Embodiments of a framework are disclosed for stair escalation to capture high resolution heart rate data that can be used to develop cardio fitness metrics related to stair climbing.

Abstract: Various examples are directed to systems and methods for operating an analyte sensor system. A sensor electronics of the analyte sensor system may access an indication that an analyte sensor has been inserted into a host. The sensor electronics may detect a property of a sensor signal generated by the analyte sensor after being inserted into the host. The sensor electronics may determine a first sensor sensitivity based at least in part on the property of the sensor signal. The sensor electronics may also determine a first analyte concentration using the sensor signal and the first sensor sensitivity.

Abstract: Systems and methods for processing sensor data and end-of-life detection are provided. In some embodiments, a method for determining the end-of-life of a continuous analyte sensor includes receiving a sensor signal from an analyte sensor. A plurality of risk factors associated with end-of-life symptoms of analyte sensors is evaluated. The risk factors include a downward drift in sensor sensitivity over time, an amount of non-symmetrical, non-stationary noise and a duration of noise. An end-of-life status of the analyte sensor is determined based at least in part on the evaluating. An output related to the end-of-life status of the analyte sensor is provided.

Abstract: In accordance with a system and/or method for monitoring an analyte concentration, a sensor signal indicative of an analyte concentration in a host may be received from an analyte sensor. The sensor signal may be filtered using a Kalman filter having process noise with a process covariance and measurement noise with a measurement covariance. The filtering may include updating a value associated with at least one of the process covariance and the measurement covariance using a value associated with one or more parameters employed in a model of the Kalman filter. A filtered sensor signal representative of the analyte concentration in the host may be output from the Kalman filter.
