Appeal No. 96-2573
Application No. 08/331,168
We find no such sampling and resampling frequencies in
Chandler employed in any such manner so as to generate a
frequency shifted optical target signal as claimed. The
examiner refers us to column 22, lines 55-59 of Chandler for a
teaching of converting the optical target input signal in
accordance with a first sampling frequency to provide a
converted input signal. While there is disclosure thereat
regarding conversion of an analog signal to a digital signal,
there is no teaching thereat of converting with a first
sampling frequency. However, we are willing to concede that
an analog-to-digital converter will inherently employ a
sampling signal in order to effect the conversion. Then, the
examiner points to column 24, lines 27-32 of Chandler for a
teaching of adjusting a second resampling frequency in
accordance with the height signal. However, when we refer to
the cited portion, we find nothing there regarding a height
signal or adjusting a resampling frequency in accordance
therewith. The cited portion is concerned only with a
bandpass filter, disclosing a certain frequency band in order
to keep label distortions to a minimum. Perhaps the examiner
intended column 22, lines 27-32 wherein, at least, there is a
