The article presents information on Vallejo, California-based Earthquake Protection Systems Inc., which has installed its proprietary Friction Pendulum bearings on 150 major construction projects worth more than 20 billion dollars, including buildings, bridges and industrial facilities. According to the company, Friction Pendulum bearings use the characteristics of a pendulum to lengthen the natural period of an isolated structure, so as to avoid the impact of an earthquake.
