Abstract

Systems and methods for processing, transmitting and displaying data received from an analyte sensor, such as a glucose sensor, are provided. In an embodiment, 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 sensor-related information comprises: activating a transceiver of a first communication device associated with an analyte sensor at a first time; and establishing a two-way communication channel with the second communication device; wherein the activating comprises waking the transceiver from a low power sleep mode using a forced wakeup from the second communication device.

Claims

1. 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 sensor-related information, comprising:

activating a transceiver of a first communication device associated with an analyte sensor, wherein the activating comprises waking the transceiver from a low power sleep mode using a forced wakeup from the second communication device;

establishing a two-way communication channel with the second communication device at a first time;

sending sensor-related information to the second communication device using the two-way communication channel during a transmission window;

deactivating the transceiver of the first communication device at a second time; and

periodically repeating the establishing, sending and deactivating, wherein a difference between the first time and the second time is less than or equal to one minute, and wherein the periodic repeating is performed at least once every 30 minutes, and wherein the forced wakeup is out of sync with the periodic establishing, sending, and deactivating.

2. The method of claim 1, wherein the establishing the two-way communication channel includes using authentication information related to the transceiver.

3. The method of claim 2, wherein the authentication information comprises a transmitter serial number.

4. The method of claim 1, wherein the transceiver of the first communication device is configured to engage in near field communication (NFC) with second communication device.

5. The method of claim 4, wherein the transceiver of the first communication device comprises an NFC tag that may be powered by the second communication device.

6. The method of claim 5, wherein the second communication device is configured to engage in NFC with the transceiver of the first communication device and wherein the second communication device comprises an NFC initiator.

7. The method of claim 6, wherein the second communication device comprises a software application that allows a user to initiate NFC with the first communication device.

8. The method of claim 7, wherein the software application instructs the user to place second communication in close proximity to the first communication device.

9. The method of claim 8, wherein close proximity comprises a distance that is less than 12 inches.

10. The method of claim 8, wherein close proximity comprises a distance that is less than 6 inches.

11. The method of claim 1, further comprising sending a calibration value to the first communication device and receiving an updated glucose value at the second communication device immediately thereafter.

12. The method of claim 1, further comprising sending new setting information to the first communication device.

13. The method of claim 1, wherein the first communication device and second communication device are paired using NFC.

14. A method of providing a user-initiated transmission pause mode between an on-body worn analyte sensing device and a hand-held display device, the method comprising:

intermittently automatically communicating analyte sensing information between an analyte sensing device and a display device at a first transmission power level;

receiving, on a user-interface of the display device, user input indicative of initiating of a transmission pause mode; and

sending a transmission pause command from the display device to the analyte sensing device in response to the receiving, wherein the intermittent automatic communication is at a second, lower transmission power level while in the pause mode, and wherein a software application running on the display device initiates the transmission pause mode responsive to a user request using the display device.

15. The method of claim 14, wherein the transmission pause mode is in compliance with the federal aviation administration guidelines for electronic devices.

16. The method of claim 14, wherein the user is requested to enter a duration of time that the analyte sensing device will remain in the transmission pause mode.

17. The method of claim 16, wherein a transceiver of the analyte sensing device is deactivated for the transmission pause mode duration, where after the transceiver is automatically activated.

18. The method of claim 14, wherein the display device is a smart phone.

19. The method of claim 14, wherein the intermittent automatic communication is ceased while in the pause mode.
