Patent ID: 8794354

Claim:
A tool for use in a wellbore, comprising a first tubular body having: a bore therethrough, an opening through a wall thereof, and a first actuation profile formed in a surface thereof adjacent the opening; a first arm: pivotally connected to a first piston, rotationally coupled to the first body, having a second actuation profile formed in an inner surface thereof and corresponding to the first actuation profile, disposed in the opening in a retracted position, movable to an extended position where an outer surface of the first arm extends outward past an outer surface of the first tubular body, and rotatable about the pivotal connection and relative to the first body during extension from the retracted position to the extended position to accommodate movement of the first arm along the first actuation profile, wherein the actuation profiles are disengaged in the retracted position; the first piston: disposed in the body bore, having a bore therethrough, and operable to move the first arm from the retracted position to the extended position in response to fluid pressure in the first piston bore exceeding fluid pressure in the opening and by moving longitudinally relative to the first body, thereby moving the first arm along the first actuation profile; an annular control module, comprising: a central bore therethrough; a lock operable to retain the first piston in the retracted position; and an electronics package in communication with an antenna and having a controller operable to release the lock in response to receiving a first instruction signal from the antenna; and the antenna in communication with the central bore for receiving the first instruction signal from a radio frequency identification (RFID) tag pumped through the central bore.
