of Fisk as indicated by the examiner. However, the details of
the oversampling and filter means clauses of claim 1 on appeal
are not specifically identified by the examiner to be found at
this location of the reference and we can find none ourselves.
The emphasis in Fisk is noise immunity by oversampling and
switch debounce being preformed in a software-oriented
approach in the single controller in such a manner as to avoid
the need for complex circuits or switches. Because Fisk is
computer-based, the artisan would have surmised that the
computer was interruptible. However, the interrelationship of
the input data change detecting means and the interrupt signal
