Patent ID: 8044629

Claim:
A self-tuning vibration absorber comprising: a carrier rod assembly, said carrier rod assembly including operatively connected thereto mounting means for mounting said carrier rod assembly to a primary system and hollow shafted motorized tuning means for tuning a phase difference between vibration of the primary system and vibration of said carrier rod assembly to 90 degrees, said hollow shafted motorized tuning means is further defined as a motorized tuning mass, said carrier rod assembly further including detecting means for detecting the vibration of the primary system and the vibration of said carrier rod assembly; and controller means in electrical connection with said detecting means and said hollow shafted motorized tuning means for controlling said tuning means based on the vibration of the primary system and said vibration of said carrier rod assembly detected and activating movement of said motorized tuning mass so that the phase difference between the primary system and vibration of said carrier rod assembly is 90 degrees and then turning off a motor of said motorized tuning mass.
