storing and updating of values in order to obtain such a history. Since page 24 indicates
that the difference equation represents an output Y for an input X, it is reasonable to infer
n
that one is keeping track of input and output values, or “lists.” Accordingly, it appears to
be a reasonable conclusion that, at the time of filing the present application, appellants had
possession of a compensator for periodically storing and updating an input list of most
recent input values and an output list of most recent output values. Clearly, based on the
equation shown at page 23, and discussed at pages 23-24 of the specification, appellants
were in possession at that time of a determination of new output values as a weighted
algebraic sum of selected ones of the input and output values of the input and output lists.
With regard to the claimed “digitally programming a compensator...for
implementing a difference equation whereby sequential outputs...to permit control of the
foundation member,” even the original claims [see original claim 1] recited and disclosed a
“programmable digital compensator” included in the “control electronics” recited to be in
“operative relationship with the assembly.” Since an original claim is its own support, it is
clear that there is adequate support for digitally programming a compensator to permit
control of the foundation member. The only question to be
