22, 23, and 27 have been withdrawn from consideration. Claims
19, 24 through 26, 29, and 30 have been canceled.
Appellant's invention relates to a system for sensing the
position of a stylus and generating a display. Claim 18 is
illustrative of the claimed invention, and it reads as
follows:
18. A system for sensing the position of a stylus
proximate a display device employing a matrix of display
electrodes which generate display electrode signals, wherein
the position sensing and display functions are performed
simultaneously, comprising:
means for generating in the stylus positioning signals;
means for coupling said positioning signals to the
display electrodes and for superimposing said positioning
signals onto the display electrode signals;
means for sensing said positioning signals from the
display electrodes; and
means, responsive to said means for sensing, for
resolving the position of the stylus in relation to the
display electrodes.
