Systems and methods for monitoring and managing life of a battery in an analyte sensor system worn by a user
Systems and methods for analyte monitoring, particularly systems and methods for monitoring and managing life of a battery in an analyte sensor system worn by a user, are provided.
1. An analyte sensor system configured to be worn by a user, comprising:
an analyte sensor;
a transceiver configured to transmit and receive wireless signals;
a battery; and
a processor configured to:
measure a value indicative of a current power level of the battery,
predict a remaining useful life of the battery based on the measured value and an assumed future usage of the analyte sensor system,
wherein the assumed future usage is determined based on stored history of prior usage of the analyte sensor system, and wherein the prior usage is related to a number of data transmission events, and different types of data transmission events that occurred within a predetermined number of past update cycles,
determine that the remaining useful life of the battery is below a predefined power level, and
cause a change in one or more data transmission operations of the analyte sensor system.
2. The analyte sensor system of claim 1 , wherein the analyte sensor system is a continuous glucose sensor system.
3. The analyte sensor system of claim 1 , where the change includes a reduction in a radio frequency transmission power level of the transceiver.
4. The analyte sensor system of claim 3 , wherein the reduction in the radio frequency transmission power level of the transceiver is preceded by a determination that the analyte sensor system is in close proximity of a display device for displaying analyte values received from the transceiver.
5. The analyte sensor system of claim 1 , wherein the change includes a limitation on bulk transfers of past measured analyte values stored at the analyte sensor system.
6. The analyte sensor system of claim 5 , wherein the limitation includes a cancellation of the bulk transfers altogether.
7. The analyte sensor system of claim 5 , wherein the limitation includes a transfer of only part of the stored past measured analyte values in the bulk transfers.
8. The analyte sensor system of claim 1 , wherein the change includes an increase in an interval between regularly-scheduled transmissions of analyte values.
9. The analyte sensor system of claim 1 , wherein the change includes skipping one or more of regularly-scheduled transmissions of analyte values.
10. The analyte sensor system of claim 1 , wherein the change includes a cancellation of regularly scheduled transmissions of analyte values and a transmission of an analyte value in response to one or more events instead.
11. The analyte sensor system of claim 10 , wherein the one or more events include a user prompt of data.
12. The analyte sensor system of claim 10 , wherein the one or more events include analyte values exceeding or falling below a threshold analyte value.
13. The analyte sensor system of claim 1 , wherein one of the type of transmissions is regularly-scheduled transmission of measured analyte values.
14. The analyte sensor system of claim 1 , wherein one of the type of transmissions is bulk-transfers of analyte values.
15. The analyte sensor system of claim 1 , wherein the assumed future usage is related to the expected frequencies of different types of transmission events.
