Patent ID: 7873493

Claim:
A method for determining a resulting value for an angular position, the method comprising: circuitry performing the following: determining a first factor and a second factor as a function of an initial angular position value; forming a first product from a first signal of a first sensor and the first factor and a second product from a second signal of a second sensor and the second factor; forming a subtraction result by subtracting the second product from the first product; comparing the subtraction result to a predetermined quantity; determining an additional first factor and an additional second factor as a function of an additional angular position, the additional angular position selected based on the comparison; forming an additional first product from the first signal and the additional first factor and an additional second product from the second signal and the additional second factor; forming an additional subtraction result by subtracting the additional second product from the additional first product; comparing the additional subtraction result to the predetermined quantity; and determining a resulting value for a first angular position based on the comparison of the additional subtraction result to the predetermined quantity.
