Abstract

Methods and apparatus for providing data processing and control for use in a medical communication system are provided.

Claims

1. A method, comprising:

receiving one or more signals associated with a monitored analyte level from an analyte sensor of an analyte monitoring device, wherein the sensor is in contact with bodily fluid under a skin surface;

retrieving a first operational state of the device, wherein the first operational state is based on a prior signal associated with the analyte sensor, wherein the prior signal is received before the one or more signals;

comparing a first signal level of the prior signal and a second signal level of the one or more signals against a predetermined level; and

transitioning the analyte monitoring device from the first operational state to a second operational state based on the comparison step.

2. The method of claim 1, wherein the second operational state is sensor inserted in response to the first signal level being below and the second signal level being above the predetermined level.

3. The method of claim 2, wherein the first signal level is obtained over a predetermined time period.

4. The method of claim 2, wherein the predetermined level includes one of 9 or less ADC counts or 18 or less ADC counts.

5. The method of claim 1, wherein the second operational state is based on a signal transition from above the predetermined level to below the predetermined level.

6. The method of claim 1, wherein the second operational state is sensor removed in response to the first signal level being above and the second signal level being below the predetermined level.

7. The method of claim 6, wherein the second signal level is obtained over a predetermined time period.

8. The method of claim 2, further including starting one or more processing timers associated with the second operational state.

9. The method of claim 8, wherein the one or more processing timers includes a calibration timer, a sensor expiration timer, or a combination thereof.

10. An apparatus, comprising:

an analyte sensor of an analyte monitoring device, wherein the sensor is in contact with bodily fluid under a skin surface and is configured to monitor analyte level in the bodily fluid; and

a data processor operatively coupled to the analyte sensor and configured;

to receive one or more signals associated with the monitored analyte level from the analyte sensor;

to retrieve a first operational state of the device, wherein the first operational state is based on a prior signal associated with the analyte sensor, the prior signal is received before the one or more signals;

to compare a first signal level of the prior signal and a second signal level of the one or more signals against a predetermined threshold; and

to transition from the first operational state to a second operational state based on the comparison step.

11. The apparatus of claim 10, further including a communication unit operatively coupled to the data processor, wherein the communication unit is configured to communicate the one or more signals and the prior signal.

12. The apparatus of claim 11, wherein the communication unit includes one of an RF transmitter, an RF receiver, an infrared data communication device, or a short-range data communication device.

13. The apparatus of claim 10, further including a memory operatively coupled to the data processor to store the one or more signals associated with the monitored analyte level, the prior signal associated with the monitored analyte level, and the first operational state.

14. The apparatus of claim 10, wherein the second operational state is sensor removed in response to the first signal level being above and the second signal level being below the predetermined threshold.

15. The apparatus of claim 14, wherein the first signal level is obtained over a first predetermined time period.

16. The apparatus of claim 15, wherein the second signal level is obtained over a second predetermined time period.

17. The apparatus of claim 10, wherein the second operational state is sensor inserted in response to the first signal level being below and the second signal level being above the predetermined threshold.

18. The apparatus of claim 17, wherein the first signal level is obtained over a predetermined time period.
