Abstract

Systems and methods for processing, transmitting and displaying data received from an analyte sensor, such as a glucose sensor, are provided. The data can be displayed on a hand-held display device having a display such as a key fob device including a user interface, such as an LCD and one or more buttons allows a user to view data, and a physical connector, such as USB port.

Claims

1. A method for transmitting data between a communication device associated with an analyte sensor and another communication device configured to provide user access to analyte values and/or information derived from analyte values, comprising:

generating sensor data using a first communication device coupled to a continuous analyte sensor of an analyte sensor system;

switching the first communication device among a plurality of transmission window states, the plurality of transmission window states including;

a first transmission window state in which the first communication device does not open a transmission window,

a second transmission window state in which the first communication device periodically opens a transmission window at a first frequency to facilitate communication with a display device configured to provide user access to analyte values or information derived from analyte values, and

a third transmission window state in which the first communication device periodically opens a transmission window at a second frequency that is less than the first frequency, wherein the first communication device switches from the second transmission window state to the third transmission window state responsive to a determination of a successful pairing of the first communication device with the display device, and availability of the sensor data generated from the continuous analyte sensor of the analyte sensor system; and

transmitting one or more beacons during one of the transmission window state.

2. The method of claim 1, wherein the first communication device switches from the first transmission window state to the second transmission window state upon actuation of a hall-effect switch or a reed switch.

3. The method of claim 1, wherein the first communication device operates in a low power mode in the first transmission window state.

4. The method of claim 1, wherein the first communication device automatically switches from the second transmission window state to the first transmission window state responsive to a determination of no successful pairing after a predetermined amount of time since switching from the first transmission window state to the second transmission window state.

5. The method of claim 1, wherein the first frequency is about 30 seconds and the second frequency is about 5 minutes.

6. A system for monitoring an analyte level of a host, the system comprising:

a first communication device operatively coupled to a continuous glucose sensor configured to generate sensor data;

a second communication device comprising a display electronics module and a user interface, the user interface comprising a second input module configured to receive user input and a display configured to display glucose information;

wherein the system is configured to;

switch the first communication device between a plurality of transmission window states, the plurality of transmission window states include;

a first transmission window state in which the first communication device does not open a transmission window to facilitate communication with the second communication device,

a second transmission window state in which the first communication device periodically opens a transmission window at a first frequency, and

a third transmission window state in which the first communication device periodically opens a transmission window at a second frequency that is less than the first frequency;

wherein the first communication device switches from the second transmission window state to the third transmission window state responsive to a determination of a successful pairing of the first communication device with the second communication device, and availability of the sensor data generated from the continuous analyte sensor; and

wherein the system is further configured to transmit one or more beacons during one of the transmission window states.

7. The system of claim 6, wherein the first communication device is configured to switch from the first transmission window state to the second transmission window state upon actuation of a hall-effect switch or a reed switch.

8. The system of claim 6, wherein the first communication device operates in a low power mode in the first transmission window state.

9. The system of claim 6, wherein the first communication device is configured to automatically switch from the second transmission window state to the first transmission window state responsive to a determination of no successful pairing after a predetermined amount of time since switching from the first transmission window state to the second transmission window state.

10. The system of claim 6, wherein the first frequency is about 30 seconds and the second frequency is about 5 minutes.
