OPINION
Claims 9 and 11 -- § 102(b) over Daniel
Daniel describes an interactive display screen (Fig. 1) having a matrix
of elements addressed by line and column (L, C) electrodes. A control
element X receives detection signals from element Re, which is associated
with image element P. An image element P may be controlled by the
electrodes and by control circuit X. Daniel 3:23 - 4:2. The image element P
may thus be actuated by either or both of electrodes L, C and receiver Re.
Receiver Re can be sensitive to radiation from a mobile emitter E (Figs. 2
and 3). Id. 4:3-14, 21-24. Emitter E is capable, in addition, of transmitting
coded orders to designated zones of the screen that can be decoded and
executed by circuits X. Id., ll. 25-31. One may thus, for example, draw
lines, having user-selectable colors, upon the screen. Id. 5:13-29.
The emitter can thus be used to superimpose information on a pre-
existing image. Daniel 6:3-5. The reference also describes circuit X as
containing a decoder D (Fig. 5) that can receive and decode coded signals
received in the first instance by receiver Re, in addition to signals received
from decoupling circuits DC1 and DC2 from the line and column electrodes.
The signals may relate to a particular image element P. A particular circuit
X also decodes signals intended for other image elements, which are
transmitted through coupling circuits to the line and column electrodes, for
reception by the intended X circuit and associated image element. Daniel
6:21 - 7:3.
The Examiner finds instant claim 9 to be anticipated by Daniel. The
Examiner reads the first pulse density capture circuit on the decoupling
circuits, and the second pulse density capture circuit on the combination of
