Medical devices and methods

A medical device comprising:

• an in vivo analyte sensor configured to generate analyte measurements associated with an analyte concentration;
• and
• processing circuitry configured to:
• generate a first analyte estimate using a first analyte estimation path;
• generate a second analyte estimate using a second analyte estimation path operating concurrently with the first analyte estimation path;
• and
• selectively provide one of the first analyte estimate or the second analyte estimate for transmission to an external device.

A system comprising:

• an on-body analyte sensor configured to generate analyte measurements;
• an electronics unit coupled to the analyte sensor;
• and
• an external device configured to communicate with the electronics unit;
• wherein the electronics unit comprises processing circuitry configured to:
• generate a plurality of analyte estimates using a plurality of analyte estimation paths operating concurrently;
• and
• selectively provide one of the plurality of analyte estimates to the external device.

A processor-implemented method comprising:

• receiving analyte measurements from an analyte sensor;
• generating a first analyte estimate using a first analyte estimation path;
• generating a second analyte estimate concurrently with the first analyte estimate using a second analyte estimation path;
• and
• selectively outputting one of the first analyte estimate or the second analyte estimate.
