Appl. No.:

10/818182

Inventors:

Dale H. Mugler - Hudson OH, US
Yan Wu - Statesboro GA, US

Assignee:

The University of Akron - Akron OH

International Classification:

G06F 11/30
G06F 15/00
G21C 17/00

US Classification:

702182

Abstract:

A system and method for determining a predicted value of a function from at least one previous value of said function and at least one second-derivative value of the function. The system includes 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 a feature 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.

Abstract:

A system and method for calculating a future function value, such as velocity, for an object, from derivative values, such as acceleration, includes a sensor, such as an accelerometer, coupled to an object, such as a car. By predetermining a sampling rate of the derivative values and determining the highest frequency in the sampled signal, a set of prediction coefficients can be derived for use in a prediction formula which generates the future function value. A processor, which derives the prediction coefficients and implements the prediction formula may use the future function value to control operation of the object or a related object. By including a past function value in the prediction formula, a highly accurate future function value can be determined.
