Abstract

Methods and apparatuses for determining an analyte value are disclosed.

Claims

1. A method, comprising:

generating a noise filtered signal associated with a monitored analyte related data stream based on one or more prior filtered signals;

detecting a signal dropout in the noise filtered signal; and

estimating, using one or more processors, a dropout compensated signal based on the noise filtered signal and the detection of the signal dropout.

2. The method of claim 1 wherein the one or more prior filtered signals includes one or more prior noise filtered signals associated with the monitored analyte related data stream.

3. The method of claim 1 further comprising generating a signal associated with the detected signal dropout, wherein estimating the dropout compensated signal includes determining a variation between the signal associated with the detected signal dropout and the generated noise filtered signal.

4. The method of claim 1 wherein estimating the dropout compensated signal includes subtracting the signal associated with the detected signal dropout and the generated noise filtered signal.

5. The method of claim 1 wherein generating the noise filtered signal includes applying a filter to the monitored analyte related data stream.

6. The method of claim 1 wherein generating the noise filtered signal includes applying a weighted average function to the monitored analyte related data stream.

7. The method of claim 1 further including outputting the dropout compensated signal, and wherein outputting the dropout compensated signal includes providing an indication associated with the noise filtered signal.

8. The method of claim 1 including transmitting one or more of the monitored analyte related data stream, the noise filtered signal, the detected signal dropout, or the dropout compensated signal.

9. The method of claim 8 wherein said transmitting includes wirelessly transmitting the one or more of the monitored analyte related data stream, the noise filtered signal, the detected signal dropout, or the dropout compensated signal.

10. The method of claim 8 including transmitting the one or more of the monitored analyte related data stream, the noise filtered signal, the detected signal dropout, or the dropout compensated signal to a remote location.

11. An apparatus, comprising:

one or more processors; and

a memory storing instructions which, when executed by the one or more processors, causes the one or more processors to generate a noise filtered signal associated with a monitored analyte related data stream based on one or more prior filtered signals, to detect a signal dropout in the noise filtered signal, and to estimate a dropout compensated signal based on the noise filtered signal and the detection of the signal dropout.

12. The apparatus of claim 11 wherein the one or more prior filtered signals includes one or more prior noise filtered signals associated with the monitored analyte related data stream.

13. The apparatus of claim 11 wherein the memory stores instructions which, when executed by the one or more processors, causes the one or more processors to generate a signal associated with the detected signal dropout and to determine a variation between the signal associated with the detected signal dropout and the generated noise filtered signal.

14. The apparatus of claim 11 wherein the memory stores instructions which, when executed by the one or more processors, causes the one or more processors to subtract the signal associated with the detected signal dropout and the generated noise filtered signal.

15. The apparatus of claim 11 wherein the memory stores instructions which, when executed by the one or more processors, causes the one or more processors to apply a filter to the monitored analyte related data stream.

16. The apparatus of claim 11 wherein the memory stores instructions which, when executed by the one or more processors, causes the one or more processors to apply a weighted average function to the monitored analyte related data stream.

17. The apparatus of claim 11 wherein the memory stores instructions which, when executed by the one or more processors, causes the one or more processors to output the dropout compensated signal.

18. The apparatus of claim 17 wherein the memory stores instructions which, when executed by the one or more processors, causes the one or more processors to provide an indication associated with the noise filtered signal.

19. The apparatus of claim 11 wherein the memory stores instructions which, when executed by the one or more processors, causes the one or more processors to transmit one or more of the monitored analyte related data stream, the noise filtered signal, the detected signal dropout, or the dropout compensated signal.
