Update: looking at the patent again: http://www.freepatentsonline.com/7349503.html Note that bb_m1thres and bb_m2thres refer to normalized, self-correlated thresholds, bb_m2count_thr refers to the number of self-correlation values (wherein a typical count would not exceed 31), and bb_use_self_corr_low refers to an enabling bit value. (but the variables are still quite confusing.) ~ w ~ On Thu, Oct 10, 2013 at 10:12 AM, w <tx2023@gmail.com> wrote: > Yup, I read the patent.
