System for imparting mechanical impulse energy to the ground
First Claim
1. A system for imparting a mechanical impulse to the earth comprising:
- an anvil for operative deployment against the earth;
a hammer operatively connected to the anvil for striking the anvil;
a control system operatively connected to the hammer for controlling the impulse energy of the hammer striking the anvil, the control system including a linear feedback system for measuring the linear position of the hammer with respect to the anvil during a force stroke, a processor for receiving linear position data from the linear feedback system and for controlling the relative speed of the hammer with respect to the anvil during a force stroke through an actuation system.

Abstract
The invention relates to an apparatus and method for imparting a precise amount of impulse energy to be delivered to the ground. The apparatus includes an anvil for operative deployment against the earth a hammer operatively connected to the anvil for striking the anvil; and a control system operatively connected to the hammer for controlling the impulse energy of the hammer striking the anvil. The control system includes a linear feedback system for measuring the linear position of the hammer with respect to the anvil during a force stroke and a processor for receiving linear position data from the linear feedback system for controlling the relative speed of the hammer with respect to the anvil during a force stroke through an actuation system.

10. A system for imparting a mechanical impulse to the earth comprising:
-
an anvil/platen/base plate assembly for operative deployment against the earth;
a hammer and mass assembly operatively connected to the anvil, the hammer/mass assembly for striking the anvil;
a control system including a servo valve, hydraulic actuator and accumulator assembly interconnected to the hammer/mass assembly for controlling the impulse energy of the hammer/mass assembly striking the anvil/platen/base plate assembly, the control system including a linear feedback loop for measuring the linear velocity and position of the hammer with respect to the anvil during a force stroke, a processor for receiving linear velocity and position data from the linear feedback loop and a proportional integrated derivative (PID) control loop to measure and correct the velocity of the hammer/mass velocity with respect to the anvil during a force stroke. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
