Application 10/326,410
which machine parameters are to be processed and stored.
(Sarangapani, Col. 4, ll. 12-20).
6. In Sarangapani, each parameter is associated with a dependency
definition that identifies the conditions under which data will be stored “for
trending purposes” (Sarangapani, Col. 4, ll. 23-25), and trend data is
gathered and stored as the dependency definition is met over a specified
trend period. (Sarangapani, Col. 4, ll. 31-33).
7 In Sarangapani, for each trending period, a single trend point is
generated for a parameter which represents either the average value,
maximum value, or minimum value in the period, and the choice of which
form is selected for the trend points is a system designer’s decision based on
what changes best indicate impending failure. (Sarangapani, Col. 4, ll. 37-
50).
8. For projecting impending failure, Sarangapani discloses
plotting the generated trend points based on actual conditions versus time.
(Sarangapani, Col. 5, ll. 51-54 and 57-59; Fig. 5, curve 44). Also plotted on
the same graph shown in Figure 5 is a separate curve 44 illustrating a
“typical” theoretical trend line based on past actual or historical information.
9. Sarangapani discloses comparing the actual trend curve 44 with
the theoretical trend curve 42 to arrive at a conclusion on whether the
machine will last longer or shorter than a machine under typical conditions,
and by how much. (Sarangapani, Col. 6, ll. 7-11).
E. Principles of law
To establish anticipation under 35 U.S.C. § 102, each and every
element in a claim, arranged as is recited in the claim, must be found in a
single prior art reference. Karsten Manufacturing Corp. v. Cleveland Golf
