obscure the basic fuzzy logic principles and that are unnecessary
to meeting the claim limitations. It will help simplify the
analysis by noting Hisano is applied simply to show a fuzzy logic
controller that takes sensor inputs, performs fuzzy logic
operations on them, and outputs the results as a control signal.
As a background of fuzzy logic for any judicial review, we cite
the article Fuzzy set and systems, in McGraw-Hill Encyclopedia of
Science & Technology (7th ed. 1992), pages 524-527. This article
is not relied on to support the rejection and therefore does not
raise a new ground of rejection. See In re Boon, 439 F.2d 724,
727-28, 169 USPQ 231, 234 (CCPA 1971) (standard work cited to
support an officially noticed fact which plays a minor role does
not raise a new ground of rejection).
To simplify the analysis we consider a single fuzzy computer
(FC) in Hisano, e.g., FC 2 in figures 1 and 3. FC 2 is attached
to MPU 1 and to a plurality of sensors 6a and to FC 3. FC 2
accepts the values of input variables (x1, y1 in the equation for
figure 2, col. 3, lines 55-56; x, y, and z in equation (1),
col. 5, line 26), via input controller 12. Figure 2 illustrates
that the values of some fuzzy input variables (e.g., x3, y3) are
obtained directly from sensors 6 (in dotted box 7), while the
values of other fuzzy input variables (the antecedents to the
rule, e.g., x1, y1) are obtained from the results of the
