Abstract: A method of measuring a physiological characteristic of a user obtains first calibrating sensor data indicative of an analyte level of the user, and produced in response to operation of a continuous analyte sensor device during a calibration period, and obtains second calibrating sensor data indicative of status or condition of the user, and produced in response to operation of a noninvasive sensor device, concurrently with operation of the continuous analyte sensor device, during the calibration period. A correlation measurement is calculated by comparing the first calibrating sensor data against the second calibrating sensor data. When the correlation measurement exceeds a threshold value, a transfer function is generated to calculate estimated values of the analyte level as a function of sensor data from the noninvasive sensor device. The transfer function is provided to a client device associated with the user.

Abstract: A physiological characteristic monitoring system includes a wearable attachment device, an electronic device, and a physiological characteristic sensor (e.g., a glucose sensor) including a portion that is insertable into subcutaneous tissue of a user to generate sensor signals indicating a physiological characteristic of the user. The electronic device includes a first connector configured to detachably couple to the physiological characteristic sensor to receive the sensor signals in a first configuration of the electronic device, a second connector configured to detachably couple to the wearable attachment device in a second configuration of the electronic device, a controller configured to determine the physiological characteristic of the user based on the sensor signals, and a display configured to display the physiological characteristic of the user.

Abstract: A physiological characteristic monitoring system includes a physiological characteristic sensor that observes a physiological characteristic and generates sensor signals based on the observation. The physiological characteristic sensor includes a sensor connector. The physiological characteristic monitoring system includes a wearable device to be worn by a user in a first configuration and having a connector to couple to the sensor connector in a second configuration. The wearable device includes a controller that receives the sensor signals from the physiological characteristic sensor in the second configuration and determines a current value of the physiological characteristic based on the sensor signals.
