Additional activities may include adjusting operation of a fluid transport mechanism based on the sensor information and baseline information, to continue moving the fluid and change the condition until the fluid is depleted from the at least one fluid container or the sensor information conforms to the baseline information to a selected degree. Additional apparatus, systems, and methods are disclosed. | 01-08-2015 |
