  • Patent number: 11633133
    Abstract: Disclosed herein are systems and methods for a continuous analyte sensor, such as a continuous glucose sensor. One such system utilizes first and second working electrodes to measure additional analyte or non-analyte related signal. Such measurements may provide a background and/or sensitivity measurement(s) for use in processing sensor data and may be used to trigger events such as digital filtering of data or suspending display of data.

  • Publication number: 20220378337
    Abstract: In implementations of adaptive systems for continuous glucose monitoring (CGM), a computing device implements an adaptive system to receive glucose data describing user glucose values measured by a sensor of a CGM system, the sensor is inserted at an insertion site. The adaptive system accesses orientation data describing forces measured by an accelerometer of the CGM system, and the adaptive system identifies a location of the insertion site based on the orientation data. Modified glucose data is generated by modifying the user glucose values based on the location of the insertion site. The adaptive system generates an indication of the modified glucose data for display in a user interface of a display device.
