Embodiments of a system and method for blur-calibration of an imaging sensor using a moving constellation are generally described herein. When the voltage exceeds a predetermined voltage, a first transistor is turned on, and a second transistor is turned off. The pads are activated by increasing fluid pressure in the annulus between the tool and tubing wall and deactivated by increasing fluid pressure through the central bore of the tool. The valve element rotates from a first position in which the inlet passages deliver pressurized air from the inlet chamber to the piston chamber, to a second position in which the exhaust passages exhaust pressurized air from the piston chamber to the exhaust chamber.
