Appeal 2007-2682
Application 10/326,410
displaying at least one of: a time, a period, a location,
and a damage level when the damage factor exceeds a
designated level.
34. A method of monitoring the effect of operating
conditions on a component of a machine, the method
comprising:
sensing at least one property associated with the
machine;
maintaining a data structure in a memory element that
determines a damage factor indicative of an instantaneous stress
applied to the component based at least in part on the at least
one property; and
processing the data structure to determine the damage
factor based on the at least one property; and
displaying at least one of: a time, a period, a location, and
a damage level when the damage factor exceeds a designated
level.
3. Sarangapani discloses a method for evaluating a machine
parameter “trend” as it approaches an impending failure limit or point of
unacceptable performance, and a method for determining a severity value for
the trend. (Sarangapani, Col.1, ll. 7-13).
4. Sarangapani discloses using sensors to sense operational
parameters of a machine and delivering sensor output signals to an
electronic module which includes a microprocessor and a memory
section 24. (Sarangapani, Col. 3, l. 52 to Col. 4, l. 5).
5. Sarangapani discloses that performance baselines are
stored within the memory section of the electronic module, and the
baselines are (1) used during performance checks of the machine to
help verify machine component health, and (2) as reference points to
determine whether the machine is in an operating condition in
