Abstract:
A method of determining a direction of rotation of a shaft is disclosed, as well as an integrated circuit chip that uses the disclosed method. The method includes receiving a first binary signal and a second binary signal from a transducer attached to the shaft, with the first and second binary signals being in quadrature. A present quadrant identification number, QID PRESENT , is determined as a two-digit binary number by left-shifting a value of the first signal and adding a value of the second signal. After a sampling interval has elapsed, the method sets a past quadrant identification number, QID PAST , to the value of said QID PRESENT , determines a new value of QID PRESENT  and calculates a value of a transition code using an equation that operates on QID PRESENT  and QID PAST . The method uses the transition code to determine a direction of rotation of the shaft.

Claim (Index 1):
A method comprising:\n receiving first and second binary signals that are in quadrature with one another; determining a present quadrant identification number (QID PRESENT ) based on the first binary signal and the second binary signal; after a sampling interval has elapsed, setting a past quadrant identification number (QID PAST ) to the value of QID PRESENT , determining a new value of QID PRESENT ; and, after determining the new value of QID PRESENT , determining a transition code as a function of QID PRESENT  and QID PAST ; and in response to a determination that the transition code is valid, using the transition code to determine a rotation direction, producing a direction of rotation signal indicative of the rotation direction, generating at least one control signal based upon the direction of rotation signal, and using the at least one control signal to control a motor.
