Patent ID: 7647208

Claim:
A method of generating a series of output signals representative of a series of time interval signals, including the steps of: (a) creating a trend line from a number of historical time interval signal values; (b) predicting a first output time interval signal value from said trend line; (c) measuring a first new time interval signal value; (d) comparing the measured first new time interval signal value to the predicted first output time interval signal value; (e) if the measured first new time interval signal value is within a pre-determined range of acceptable values, using the measured first new time interval signal to update said trend line and if the measured first new time interval signal value is outside the pre-determined range of acceptable values, using the predicted first output time interval signal value to update said trend line; and (f) repeating steps (a) to (e) to predict at least a second output time interval signal value.
