First Claim
Patent Images
1. A sensor system for measuring an analyte in a host, the system comprising:
- a sensor configured to measure an analyte concentration in a host; and
electronics operably connected to the sensor and configured to initialize a sensor session after the sensor is in communication with a biological sample of the host, wherein the electronics are configured to confirm removal of the sensor from contact with the biological sample of the host prior to initialization of another sensor session.
