Abstract

Claims (18)

1. An analyte monitoring system comprising:

an analyte sensor configured to generate and convey sensor data, wherein the analyte sensor comprises:

an analyte indicator including indicator molecules having one or more detectable properties indicative of an amount or concentration of an analyte in proximity to the analyte indicator; and

an inductor configured to wirelessly convey the sensor data;

a transceiver configured to:

receive sensor data conveyed by the analyte sensor,

calculate one or more analyte measurements during a first period of time using at least the received sensor data,

calculate a duration of time that a host uses the analyte monitoring system during the first period of time, and

calculate an average time that the host uses the analyte monitoring system during a second period of time or a percentage of the first period of time that the host uses the analyte monitoring system, wherein the average time or the percentage is calculated based on at least the calculated duration; and

a display device configured to receive and display the one or more calculated analyte measurements from the transceiver and to display a report indicating the average time that the host uses the analyte monitoring system or the percentage of the first period of time that the host uses the analyte monitoring system;

wherein, in calculating the duration of time that the host uses the analyte monitoring system during the first period of time, the transceiver is configured to:

determine a number of analyte concentrations calculated by the transceiver during the first period of time;

calculate a ratio between the determined number of analyte concentrations and an expected number of analyte concentrations during the first period of time; and

multiply the first period of time by the calculated ratio.

2. The analyte monitoring system of claim 1 , wherein the transceiver is positioned such that the transceiver is operatively linked to the analyte sensor.

3. The analyte monitoring system of claim 1 , wherein the analyte sensor further comprises:

a light source configured to emit excitation light that interacts with the indicator molecules; and

a photodetector that is sensitive to emission light emitted by the indicator molecules and configured to generate a signal that is indicative of a level of the emission light.
