Appeal No. 96-0550
Application 07/960,148
730 F.2d 1452, 1463, 221 USPQ 481, 489 (Fed. Cir. 1984).
However, an examiner may reject a claim if it is reasonable to
conclude that one skilled in the art would be unable to carry out
the claimed invention. Eynde, 480 F.2d at 1370, 178 USPQ at 474.
In the present case the examiner is of the opinion that
the disclosure fails to disclose how to use gray scale to soften
the edges of the image reflected on the windshield (Examiner's
Answer at page 3).
The specification states that a double image is
produced when an image is projected onto an automotive windshield
due to the reflection of the projected image from both the inside
and outside reflecting surfaces of the windshield (Specification
at page 14). The specification also discloses:
The effect of the double image can be
made less noticeable by "softening" the
edges of the projected image. This
softening of the edge of the image is
achieved by surrounding the periphery of
the activated pixels on the deformable
mirror device with pixels that are
activated a smaller fraction of the
time, i.e., using gray scale. The "next
nearest neighbor" pixel may be activated
with a smaller duty cycle than the
pixels that are "nearest neighbors" to
the periphery of the fully activated
pixels, causing the edges of the image
to be less distinct and the double image
to be less noticeable. [Specification
at page 15]
