1. A drawing tablet device with data capture comprising:
- a drawing layer adapted to display an image drawn upon said drawing layer by application of pressure on said drawing layer;
a data capture device including a data capture layer capturing the image drawn upon said drawing layer as electronic data representing the image; and
a separating layer separating said drawing layer from said data capture layer, said separating layer having properties preventing structure provided on said data capture layer from impacting the image drawn upon said drawing layer.

Abstract
A writing/drawing tablet utilizing a data capture device such as a pressure sensitive display with data capture component that can capture data from the resulting image drawn on the device for storage. In general, Bistable Liquid Crystal Displays (BLCD), and in particular, Cholesteric Liquid Crystal Displays (ChLCDs), can be utilized in the tablet. The tablet can also be adapted to connect to external devices for displaying images being drawn on the tablet or that were previously stored.

13. A drawing tablet device with data capture comprising:
-
a drawing layer adapted to display an image drawn upon said drawing layer by application of pressure on said drawing layer; a specialized stylus; a data capture device including a data capture layer having a conductive grid provided on a surface thereof capturing the image drawn upon said drawing layer by said specialized stylus as electronic data representing the image; and a separating layer separating said drawing layer from said data capture layer, said separating layer having properties for preventing the conductive grid from impacting drawing layer during said application of pressure, wherein an image drawn upon said drawing layer using means other than the specialized stylus is not captured as electronic data representing the image. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

32. A drawing tablet device with data capture comprising:
-
a switch selectable between a first drawing mode and a second drawing mode; a drawing layer adapted for responding to an image drawn upon said drawing layer by application of pressure on said drawing layer such that when said first drawing mode is active, said drawing layer displays the image, and when said second drawing mode is active, said drawing layer does not display the image; a specialized stylus; and a data capture device including a data capture layer electronically capturing a motion of the specialized stylus on said drawing layer during both said first drawing mode and said second drawing mode. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
