Appellant further asserts (brief, page 10) that the
“values of a maximum slope, R, [sic ] and dead time L . . . .2
do not appear to be dynamic process characteristics of a PID
controller.” We find that Ueda (col. 5, lines 31-33)
specifically refers to R, L, and K as “characteristics of the
process.” In addition, we find that the plurality of process
variables R, L, and K to be dynamic in view of the disclosure
of Ueda (col. 5, lines 34-44) that the tuning parameters K ,

K , and K are determined by the following equations:3

K =C ·R·L; K =C ·R, and K =C ·K where C , C , and C are constants

Ueda discloses (col. 5, lines 62 et seq.) that when the tuning
factors K , K , and K are decided, all of the membership

the tuning parameters in the manner set forth by Ueda.
