  • taking a series of measurements of a parameter associated with the motor or one of the drive train components;

    after each measurement in the series of measurements is taken, performing a comparison between the measurement taken and a calculated threshold value before taking the next measurement in the series of measurements; and

    if the comparison indicates that the measurement taken is less than the calculated threshold value, determining that there is no occlusion, and delivering said fluid to the user'"'"'s body.
