Patent ID: 8332181

Claim:
A method to align a first object with a second object, comprising: positioning a portable device at a known position within a reference frame by mating an alignment key of a calibration station with an alignment socket of the portable device in a predetermined location on a calibration station, wherein the portable device comprises an inertial sensor; attaching the portable device to a predetermined location on the first object by mating the alignment key of to the first object with an alignment socket formed on the portable device; learning a position/orientation of the object relative to a reference frame using the inertial sensor of the portable device; moving the portable device from the first object to a predetermined location on the second object by mating an alignment key of the second object with the alignment socket of the portable device; determining relative position data relating the relative position of the second device with respect to the first device using the inertial sensor of the portable device; and aligning the first object with the second object based on the relative position data.
