Various embodiments of the present invention provide systems and methods for determining a location of a spiral pattern. As an example, a location detection circuits is discussed that includes: a pattern detection circuit, a computation circuit, and a center determination circuit. The pattern detection circuit is operable to identify a subset of a series of data samples corresponding to a defined pattern, and to indicate a location of the identified subset of the series of data samples. The series of data samples corresponds to a spiral pattern. The computation circuit operable to sum an absolute value of each sample of the subset of the series of data samples to yield a sum. The center determination circuit operable to identify a location of the spiral pattern using the sum.
