Abstract
A telemetering system is disclosed for communicating command signals to a downhole adjustable blade stabilizer, and for transmitting encoded time/pressure signals back to the surface. The command signal provides information regarding a desired blade position for an adjustable blade stabilizer. The stabilizer sets a positioning piston in response to the command signal to limit the extent of blade expansion. A position sensor is provided in association with the positioning piston to measure precisely the position of the blades. An encoded signal is generated in response to the measurement and is transmitted to the surface in a combined time/pressure format to uniquely identify the position of the blades.
