ABSTRACT:
Method and apparatus for actuating a counting device for recording and stng data. The invention comprises an activator for a counter device and includes a mass or weight having an eccentric center of mass which is freely pivotable in one plane in response to an externally applied impulse force of a predetermined magnitude to apply a torque force to a shaft which, on rotation thereof under the influence of said torque force, activates the counter mechanism to record a count. Means are also provided to apply counter torque force of a constant predetermined magnitude or value to the shaft so that the counting device is actuated only in response to a resultant torque force of a predetermined magnitude or value generated by the impulse.
