Appeal No. 1997-3819
Application No. 08/278,153
As stated above, we find that the scope of claim 1
includes that the projected line forms an image on the surface
of the object. We find that the scope of claim 9 similarly
includes that an image of a line is projected into the
scanning area, and that an image is formed on the surface of
the object. These limitations are found in the recitation of
“means for projecting at least one line onto a scanning area”
and “means for detecting an image formed on a surface of the
log.”
We find that Olsson teaches a system for orientating a
log in a saw mill for optimum cutting. See Column 4, lines 6
to 15. Olsson teaches that the log is observed by either two
or three cameras which traverse the log scanning it’s surface
contour. See Figures 1, 6 and 8a, the description in Column
7, line
51 through Column 8, line 37 and the description in Column
8, line 63 through 68. Olsson teaches that the scanned data
is
used to generate a model which in a simplified form defines
the contour of the log. See Figure 7, description in Column
7, lines 30 to 51 and Column 9, lines 8 through 12. We find
