Appeal No. 96-1445
Application 08/371,684
electronic and mechanical controls which are necessary for
controlling the rotatability of the receiving screen for the
viewer to essentially "see" a 3-D depiction. Various light
receiving and transmitting means in the form of mirrors and
lenses including the dichroic mirrors of Ernstoff obviously
would have been employed to convey a single planar image from
plural image sources/beams. Taken in this light, therefore,
we do not agree with the positions advocated by appellants in
the initial portions of the argument section of the principal
Brief on appeal as to independent claim 1 on appeal.
As to the features in dependent claims we note the
following. As to claim 2 various circuits clearly control the
rotatability of the image projection apparatus in both Hirsch
and Collender. The beam intensity control features in
dependent claims 3 and 4 are met by the collective teachings
of Collender, Ernstoff and Hornbeck. As to the features in
dependent claims 5 to 8, they are obviously met by the
teachings in Hornbeck, which appellants’ own invention relies
upon as a basis for their invention disclosure. The
simultaneity feature of dependent claims 9 through 16 is
taught by Collender and Ernstoff with similar teachings
