Classification: CPC A  G | IPC A  G

Claim 8:
9. A method for air bubble detection comprising:
determining a first moving average for a first period of time based upon first temperature data generated by a first temperature sensor during the first period of time;
determining a second moving average for the first period of time based upon second temperature data generated by a second temperature sensor during the first period of time;
determining a first air presence parameter based upon a comparison between the first temperature data and the first moving average and a comparison between the second temperature data and the second moving average;
determining a second air presence parameter based upon a comparison between the first temperature data, the second temperature data, and one or more calibrated air thresholds;
determining a third air presence parameter based upon a comparison between a first temperature data entry and each second temperature data entry; and
detecting a presence of an air bubble within a fluid flow system based upon the first air presence parameter, the second air presence parameter, and the third air presence parameter.
