| 20090053072 | Integrated "One Pump" Control of Pumping Equipment - Methods and systems for improving the efficiency of a pumping process by controlling the operation of the pumps involved based on certain parameters characterizing the pump. A pump unit is coupled to a pump controller which is in turn, coupled to a pump modulator. A master controller drives the pump modulator based on a desired output parameter for the system. The pump modulator then drives each pump unit through its corresponding pump controller in a manner for the system to achieve optimal performance. | 02-26-2009 |
| 20090308603 | Work string controller - Well bore servicing equipment is provided. The well bore servicing equipment comprises a first manipulator to grip a well bore work string, to raise the work string, and to lower the work string. The well bore servicing equipment further comprises a controller to receive a work string trajectory input and to automatically control the first manipulator to raise and lower the work string substantially in conformance with the work string trajectory input. | 12-17-2009 |
