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 exchanging analyte data among communication devices, the method comprising:

receiving, at an analyte sensor communication device associated with an analyte sensor, a request from a primary display device configured to provide user access to analyte values for data stored in memory of the analyte sensor communication device;

transmitting, from the analyte sensor communication device, the stored data to the primary display device in response to the request from the primary display device, wherein the data comprises previous analyte sensor measurements in addition to analyte sensor measurements of a scheduled analyte sensor measurement transmission;

establishing a wireless communication channel between the primary and a secondary display device;

receiving by the secondary display device the requested analyte data and time synchronization information upon being forwarded by the primary display device over the established wireless communication channel; and

using the received time synchronization information, initiating an establishment of a direct wireless communication channel by the secondary display device with the analyte sensor communication device to receive analyte sensor measurement data generated by the analyte sensor from the analyte sensor communication device.

2. The method of claim 1, wherein the transmitting the stored data comprises transmitting a data set of analyte sensor measurements corresponding to a pre-determined time interval that includes the previous analyte sensor measurements.

3. The method of claim 2, wherein the pre-determined time interval corresponds to a twenty-four hour period of analyte sensor measurements.

4. The method of claim 3, wherein the previous analyte sensor measurements comprise a sub-set of the data set of analyte sensor measurements.

5. The method of claim 4, wherein the data is transmitted in a compressed format.

6. The method of claim 5, wherein the analyte sensor measurements of the scheduled analyte sensor measurement transmission include a most recent glucose measurement value.

7. The method of claim 6, wherein the previous analyte sensor measurements include past glucose measurements.

8. The method of claim 7, wherein the primary display device determines a range of missing data and transmits a request for the range of missing data.

9. The method of claim 8, wherein the range of missing data comprises a range of glucose measurement related data that is missing from memory of the primary display device.

10. The method of claim 9, wherein, after receiving the request for the range of missing data from the primary display device, the analyte sensor communication device transmits the requested range of missing data or transmits a data set of previous analyte sensor measurements, the data set including the requested range of missing data.

11. The method of claim 1, wherein the data comprises technical support data, wherein the technical support data is stored in a log file in the memory of the analyte sensor communication device;

and wherein the method further comprises;

determining that the primary display device should receive at least some of the stored technical support data; and

transmitting, using the analyte sensor communication device, a message indicative of the determination; and

wherein;

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

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

12. The method of claim 11, wherein the message is included in a beacon transmitted by the analyte sensor communication device, and/or wherein the primary display device is configured to automatically send the at least some of the transmitted technical support data to a technical support communication device.

13. The method of claim 1, further including executing an authentication procedure to establish the wireless communication between the primary and the secondary display devices.

14. The method of claim 1, wherein the time synchronization information includes timing information for establishing a communication channel with the analyte sensor communication device.

15. A system for exchanging analyte data among communication devices, the system comprising:

a primary display device configured to provide user access to analyte values and establish a wireless communication channel with a secondary display device;

an analyte sensor communication device associated with an analyte sensor, wherein the analyte sensor communication device is configured to receive a request from the primary display device for data stored in memory of the analyte sensor communication device, and transmit the stored data to the primary display device in response to the request from the primary display device, wherein the data comprises previous analyte sensor measurements in addition to analyte sensor measurements of a scheduled analyte sensor measurement transmission; and

the secondary display device configured to provide user access to analyte values, receive time synchronization information and the requested analyte data upon being forwarded by the primary display device over the established wireless communication channel, and use the received time synchronization information to initiate establishment of a direct wireless communication channel with the analyte sensor communication device to receive analyte sensor measurement data generated by the analyte sensor from the analyte sensor communication device.

16. The system of claim 15, wherein the transmission of the stored data comprises transmission of a data set of analyte sensor measurements corresponding to a pre-determined time interval that includes the previous analyte sensor measurements.

17. The system of claim 16, wherein the pre-determined time interval corresponds to a twenty-four hour period of analyte sensor measurements.

18. The system of claim 17, wherein the previous analyte sensor measurements comprise a sub-set of the data set of analyte sensor measurements.
