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 that allows a user to view data, and a physical connector, such as USB port.

Claims

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

establishing a communication channel between a secondary communication device and a first communication device during a transmission time window of a sensor session;

determining whether a primary communication device has previously been in communication with the first communication device during the sensor session; and

rejecting requests for data or commands sent by the secondary communication device to the first communication device if the primary communication device has not been in communication with the first device during the sensor session.

2. The method of claim 1, wherein the communication between the primary communication device and the first communication device comprises control information for initiating a sensor session.

3. A system for monitoring an analyte level of a host, the system configured to perform the method of claim 1, wherein the first communication device comprises a sensor electronics module, the sensor electronics module configured to electronically couple to an analyte sensor and to generate an analyte data stream using the analyte sensor.

4. A method of transmitting data between a first communication device associated with an analyte sensor and a primary communication device and a secondary communication device, each of the primary communication device and the secondary communication device configured to provide user access to analyte values and/or information derived from analyte values, comprising:

determining whether a first communication channel has been established between a first communication device and a primary communication device during a time window; and

establishing a second communication channel between the first communication device and a secondary communication device during the time window only if the first communication channel was established during the time window.

5. A system for monitoring an analyte level of a host configured to perform the method of claim 4, wherein the first communication device comprises a sensor electronics module, the sensor electronics module configured to electronically couple to an analyte sensor and generate an analyte data stream using the analyte sensor.

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

switching a first communication device between a plurality of transmission window states, the plurality of window transmission modes 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, 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; and

transmitting one or more beacons during each transmission window state.

7. The method of claim 6, 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.

8. The method of claim 6, wherein the first communication device automatically 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.

9. The method of claim 6, the first communication device automatically switches from the second transmission window state to the third 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 method of claim 6, wherein the first frequency is about 30 seconds and the second frequency is about 5 minutes.

11. A system for monitoring an analyte level of a host, the system configured to perform the method of claim 6, wherein a first communication device comprises a sensor electronics module, wherein the sensor electronics module is configured to electronically couple to an analyte sensor and generate an analyte data stream using the analyte sensor.

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

storing technical support data in a log file in memory in a first communication device;

determining that a second communication device should receive at least some of the stored technical support data;

transmitting, using the first communication device, a message indicative of the determination;

receiving a request from the second communication device for at least some of the stored technical support data responsive to the transmitted message; and

transmitting the at least some of the stored technical support data.

13. The method of claim 12, wherein the message is included in a beacon transmitted by the first communication device.

14. The method of claim 12, wherein the message consists of a bit.

15. A system for monitoring an analyte level of a host configured to perform the method of claim 12, wherein a first communication device comprises a sensor electronics module, wherein the sensor electronics module is configured to electronically couple to an analyte sensor and generate an analyte data stream using the analyte sensor.
