1. A system for preventing damage from an earthquake to an object, having a foundation anchored to a ground surface, which is generally horizontally oriented as defined relative to a gravitationally defined vertical direction, the system comprising:
- means for guiding mounted on the foundation and on the object for allowing relative displacement between the object and the foundation in at least one horizontal direction;
at least one actuator is capable of displacing the object in the at least one horizontal direction relative to the foundation as allowed by the means for guiding;
a central processing unit, where the at least one actuator is communicated with the central processing unit; and
at least one displacement sensor,where the central processing unit is communicated with the at least one displacement sensor,where the at least one displacement sensor is capable of detecting a displacement of the foundation in real time and/or the ground surface and/or the object and capable of inputting displacement data in real time to the central processing unit, andwhere the central processing unit is programmed to activate the actuator in real time in dependence on the displacement data so that the object is displaced relative to the foundation in real time, such that a maximum horizontal displacement vector of the object is kept substantially smaller than a horizontal maximum displacement vector of the foundation.

Abstract
An object, such as a building, provided with a system for preventing damage from earthquakes to the object, said system comprising:
- a foundation anchored to the ground;
- guide means mounted on said foundation and on said object arranged to allow relative displacement between the object and the foundation in at least one horizontal direction;
- at least one actuator arranged to displace said object in said at least one direction relative to said foundation;
- said at least one actuator being connected to a central processing unit;
said central processing unit being connected to at least one displacement sensor;
said at least one displacement sensor being arranged to detect in real time displacement of said foundation and/or the ground and/or said object and to input in real time data about said displacement to said central processing unit; and
said processing unit being programmed to activate in real time said actuator in dependence on said data in such a manner that said object is displaced relative to said foundation in real time, such that the maximum displacement vector of the object relative to the earth'"'"'s gravitational field is kept substantially smaller than the maximum displacement vector of said foundation relative to the earth'"'"'s gravitational field.

17. A method for preventing damage from an earthquake to an object having a foundation anchored to a ground surface, which is generally horizontally oriented as defined relative to a gravitationally defined vertical direction, the method comprising:
-
providing means for guiding mounted on the foundation and on the object arranged to allow relative displacement between the object and the foundation in at least one horizontal direction; providing at least one actuator capable of displacing the object in the at least one direction relative to the foundation, the at least one actuator being communicated to a central processing unit, the central processing unit being communicated with at least one displacement sensor; detecting displacement of the foundation and/or the ground surface and/or the object the at least one displacement sensor using the at least one displacement sensor; inputting displacement data in real time to the central processing unit; and
activating the actuator in real time using the central processing unit in dependence on the displacement data so that the object is displaced relative to the foundation in real time, so that a maximum horizontal displacement vector of the object is kept substantially smaller than a maximum horizontal displacement vector of the foundation.
