摘要： The present disclosure describes a multi-analyte sensor system that detects artifacts using multiple analytes. According to an embodiment, the multi-analyte sensor system includes a first analyte sensor, a second analyte sensor, and a sensor electronics module. The first analyte sensor produces a first analyte signal stream indicating a level of a first analyte. The second analyte sensor produces a second analyte signal stream indicating a level of a second analyte different from the first analyte. The sensor electronics module detects, based on the first analyte signal stream and the second analyte signal stream, at least one of a compression event or a dip and recover event and in response to detecting at least one of the compression event or the dip and recover event, make an adjustment related to at least one of the first analyte sensor or the first analyte signal stream based on the event.

摘要： Systems and methods for compensating for effects of temperature on implantable sensors are provided. In some embodiments, systems and methods are provided for measuring a temperature to determine a change in temperature in a sensor environment. In certain embodiments, a temperature compensation factor is determined based on a change in temperature of the sensor environment. The temperature compensation factor can be used in processing raw data of an analyte signal to report a more accurate analyte concentration.

摘要： Systems and methods for continuous measurement of an analyte in a host are provided. The system generally includes a continuous analyte sensor configured to continuously measure a concentration of analyte in a host and a sensor electronics module physically connected to the continuous analyte sensor during sensor use, wherein the sensor electronics module is further configured to directly wirelessly communicate sensor information to one or more display devices. Establishment of communication between devices can involve using a unique identifier associated with the sensor electronics module to authenticate communication. Times tracked at the sensor electronics module and the display module can be at different resolutions, and the different resolutions can be translated to facilitate communication. In addition, the frequency of establishing communication channels between the sensor electronics module and the display devices can vary depending upon whether reference calibration information is being updated.
