Abstract:
1. A system for determining a predicted value of a function from at least one previous value of the function and at least one second-derivative value of the function, the system comprising: a sensor provided to sense a second-derivative value of the function and transmit an oscillatory signal representing the sensed second-derivative value; a computer-readable memory in communication with the sensor to store the previous value of the function and the second-derivative value; and means for computing the predicted value of the function using an integration algorithm including a coefficient of integration that is dependant upon at least a frequency of the signal, wherein the predicted value of the function is a position value and the second-derivative value of the function is an acceleration value and the function is expressed as: wherein the terms expressed generally as c p (b) represent the p th coefficient associated with a term of the b th derivative, T is a sampling period, H equals the number of previous second-derivative values sensed, M is a number of previous function values, h is a numerical value within a range of from 0 to H, m is a numerical value within a range of from 1 to M, x(t) is the predicted value of the function at time t, and x″(t−hT) represents a second derivative of the function taken with respect to time and evaluated at time t−hT.
