then employed to acquire the optical target on the surface of
the package.
We would agree with the examiner that Chandler is clearly
related to the instant claimed invention with regard to
optically readable labels on packages. However, while many 5
of the elements are the same, including, for example, a height
sensor, whereas Chandler is concerned with encoding and
retrieving information on and from an optically readable
label, the instant claimed invention is concerned with optical
target acquisition. To that end, the instant claims call for
converting the optical target input signal in accordance with
a first sampling frequency to provide a converted input signal
and for adjusting a second resampling frequency in accordance
with the height signal. Then, a second reconverting means
receives the converted input signal and reconverts the
converted input signal in accordance with the second
resampling frequency to generate a frequency shifted optical
target signal which is then employed to acquire the optical
target on the surface of the package.
5Both the Chandler patent and the instant application
are assigned to the same assignee, United Parcel Service of
America, Inc.
