    摘要: A method for controlling a pump for delivery of liquid to an organ over a series of fixed-length time intervals f, each interval f comprising a time t1 and a time t2 wherein t1+t2 equals the length of interval f. The method comprises allowing output pressure of the pump to decrease over time t1, increasing output pressure of the pump over time t2, comparing achieved pump output pressure to a predetermined pressure at about the end of interval f, and at least one of (i) adjusting t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f, and (ii) adjusting a rate of change of the output pressure during at least one of t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f.

    摘要: Air bubbles may be characterized by an air bubble detector by choosing an optimum set of frequencies and then comparing a return signal from a sensor receiving those frequencies against an internal reference. The number of pulses that exceed the internal reference represents a width and may be counted. The width, as counted, may be correlated to bubble characteristics including volume.
