Patent ID: 8127904

Claim:
An automatic energy dissipation system, comprising: a sensor for detecting a disruptive force applied to a structure; a processor connected to said sensor, configured for determining a control signal based on a sensing data received from said sensor; an energy absorbing device for coupling to said structure; and an actuator, coupled to said processor and connected to said energy absorbing device, for tuning said energy absorbing device based on said control signal generated by said processor; wherein said energy absorbing device is a base isolator configured for: adjusting a resonance frequency of said structure; and generating a damping force to reduce a structural response to said disruptive force applied to said structure; further wherein said base isolator comprises: a base adapted to attach to a support member of said structure; a cover coupled to said base in a manner so as to form an enclosure, wherein said cover is adapted to attach to said base and said structure; and further wherein said cover of said base isolator further comprises: a rigid layer; a resilient layer; and a plurality of side plates; wherein said rigid layer and said resilient layer are substantially semicircular in shape, having substantially the same center and having respective ends configured to attach to said base; and wherein said rigid layer acts as a restraining material for said resilient layer when said disruptive force is applied to said cover, and an energy absorbing material situated within said enclosure, wherein said enclosure is coupled to said actuator in a manner so that a stiffness of said enclosure may be controlled by activating said actuator.
