Abstract

Systems and methods for a continuous monitoring of analyte values received from an analyte sensor system are provided. One method for a wireless data communication between an analyte sensor system and a mobile device involves storing identification information associated with a transceiver of the analyte sensor system, the identification information entered by a user of the mobile device via a custom application running on the mobile device; causing the custom application to enter a background mode; searching for advertisement signals; receiving an advertisement signal from the transceiver; authenticating the transceiver based on the identification information; prompting the user to bring the custom application to a foreground mode; causing the custom application to request a confirmation from the user that a data connection with the transceiver is desired; receiving the confirmation from the user; and completing the data connection with the transceiver.

First claim

What is claimed is:

1. A method for transmitting data between a first communication device associated with an analyte sensor and one or more display devices configured to provide user access to analyte values and/or information derived from analyte values, comprising:
switching among a plurality of communication states, wherein a first communication state includes:
periodically opening a first transmission window according to a first time interval to provide a first display device with sensor data from the first communication device that is associated with the analyte sensor;
determining to vary the first time interval based on one or more criteria, wherein the one or more criteria is selected from a group consisting of: sensor data, monitored battery life of the first communication device, type of the first display device, user instructions received from the first display device, and timing of sensor session;

switching to a second communication state from the first communication state responsive to the determination, wherein the second communication state includes:
varying the first time interval to a second time interval; and
periodically opening a second transmission window according to the second time interval to continue to provide the display device with updated sensor data from the first communication device.

2. The method of claim 1 , wherein the second time interval is varied to be shorter in duration than the first time interval when the sensor data indicates a low glucose value.

3. The method of claim 1 , wherein the second time interval is varied to be longer in duration than the first time interval when the battery life of the first communication device meets or exceeds a threshold.

4. The method of claim 1 , wherein the first time interval is a duration of time between closing and re-opening the first transmission window in the first communication state.

5. The method of claim 1 , wherein the first time interval is varied based on the user instructions indicating a physical activity performed by a user of the first communication device.

6. The method of claim 1 , wherein the second time interval is a duration of time between closing and re-opening the second transmission window in the second communication state.

7. The method of claim 1 , wherein the first time interval is varied when the timing of the sensor session indicates that a new sensor is being used.

8. A system for wirelessly exchanging glucose information between devices, the system comprising:
a sensor electronics module operatively coupled to a continuous glucose sensor; and
a first display device comprising a display electronics module and a user interface, the user interface comprising an input module configured to receive user input and a display configured to display glucose information, wherein the system synchronizes the sensor electronics module and the first display device to switch among a plurality of communication states, wherein a first communication state includes:
periodic opening of a first transmission window according to a first time interval to provide the first display device with sensor data from the sensor electronics module;
determining to vary the first time interval based on one or more criteria wherein the one or more criteria is selected from a group consisting of: sensor data, monitored battery life of the sensor electronics module, type of the first display device, user instructions received from the first display device, and timing of sensor session;

wherein the system is further configured to switch to a second communication state from the first communication state responsive to the determination, wherein the second communication state includes:
variation of the first time interval to a second time interval; and
periodic opening of a second transmission window according to the second time interval to continue to provide the first display device with updated sensor data from the sensor electronics module.

9. The system of claim 8 , wherein the second time interval is varied to be shorter in duration than the first time interval when the sensor data indicates a low glucose value.

10. The system of claim 8 , wherein the second time interval is varied to be longer in duration than the first time interval when the battery life meets or exceeds a threshold.

11. The system of claim 8 , wherein the first time interval is a duration of time between closing and re-opening the first transmission window in the first communication state.

12. The system of claim 8 , wherein the user instructions received from the first display device and the first time interval is varied based on the user instructions indicating a physical activity performed by a user of the sensor electronic module.

13. The system of claim 8 , wherein the second time interval is a duration of time between closing and re-opening the second transmission window in the second communication state.

14. The system of claim 8 , wherein the first time interval is varied when the timing of the sensor session indicates that a new sensor is being used.
