The present invention provides an ultrasonic diagnostic apparatus. The determination of the optimal access areas or points is based in part on the location of the device, the specified user preferences, serviceapplication requirements and the capabilities of available access network connections. The arrangement of several deoxygenators for a single fuel stream improves removal of dissolved oxygen and provides for scalability of the fuel system to meet application specific demands. The device may be implanted in the abdomen using a laparoscopic or other method.
