weight setting means. Helldörfer would not have suggested a
weight setting means operative to change weight factors during
each sampling cycle of the geomagnetic sensor because the
weight factor k in Helldörfer is selected as a function of the
sampling interval and would remain the same as long as the
sampling interval is not changed. When the weighting factor k
is changed in Helldörfer, it is changed as a function of
sampling time and not as a function of the deviation in
sampled values as recited in claim 15.
In summary, the examiner’s attempt to equate the
claimed weight setting means with a standard statistical
method is in error. Therefore, the examiner has not
established a prima facie case of the obviousness of
independent claim 15. Thus, we do not sustain the rejection
of claim 15 or of claims 16 and 23 which are grouped
therewith.
We now consider the rejection of claims 19 and 20
based on Helldörfer and Ueno and of claim 22 based on
Helldörfer and Kendall. Each of these claims depends from
claim 15. The additional references were cited only to meet
