DCFirst Claim
1. A portable computer comprising:
- a first panel having a first flat surface;
a second panel having a second flat surface;
hinge means for joining said first panel to said second panel such that said first flat surface is juxtaposed to said second flat surface in a closed position and is disposed side by side in a common plane in one of a selection of open positions;
said first flat surface comprising a first digitizer;
said second flat surface comprising a second digitizer and a display juxtaposed together to form a digitizer-display unit; and
a stylus connectable to at least one of said first panel and said second panel for interacting with at least one of said first digitizer and said second digitizer, wherein data entered on one of said digitizers and displayed on said digitizer-display unit is freely alterable on said digitizer-display unit.

Abstract
A keyboardless portable computer simulates a foldable notepad and has a display which can be reoriented to the convenience of the user, carried in a self-protecting closed position and operated in any convenient open position. The computer has a first flat panel, a second flat panel and hinge means for joining the first panel to the second panel such that the first flat surface is juxtaposed to the second flat surface in a closed position and is disposed side by side in a common plane in one of a selection of open positions. The first flat surface comprises a first digitizer and the second flat surface comprises a second digitizer, and a stylus is provided which is connectable to at least one of the panels for interacting with at least one of the digitizers. One of the digitizers includes a flat panel display through which visual output is provided. Thus, registration of a written symbol on the surface of the panel produces a displayed symbol, preferably at the position of registration. The panels may be detachable at the hinge means, folded back to back to one another for compact usage and a second hinge on a digitizer panel permits a bound paper notebook to be interleaved with a thin digitizer.

16. A portable computer comprising:
-
a first panel having a first flat surface; a second panel having a second flat surface; hinge means for joining said first panel to said second panel such that said first flat surface is juxtaposed to said second flat surface in a closed position and is disposed side by side in a common plane in one of a selection of open positions; said first flat surface comprising a first digitizer; said second flat surface comprising a second digitizer; a stylus connectable to at least one of said first panel and said second panel for interacting with at least one of said first digitizer and said second digitizer; a primary axis; a secondary axis; a plurality of hinge brackets; a first securing means wherein said primary axis inserts through said first panel and a first, second, third and fourth of said hinge brackets so that said first panel pivots about said primary axis, or held stationary as said securing means secures said primary axis and said first panel; and a second securing means wherein said secondary axis inserts through said second panel and a first, second, third and fourth of said hinge brackets so that said second panel pivots about said secondary axis, independent of said first panel, or is held stationary as said second securing means secures said secondary axis and said second panel.

17. A method for operation of a personal computer that includes at least a first and a second digitizer, in a variable rotational orientation one to the other for coordinating changes in said orientation and wherein said second digitizer includes a display so that data inputted to said personal computer is displayed and is freely alterable on said second digitizer, said method comprises the steps of:
-
storing an initial set of rotation values; indicating said change in said orientation to said computer; comparing said stored rotation values to said change to determine if different; and
if differentrecognizing and storing of a new set of rotation values corresponding to said change in said orientation. - View Dependent Claims (18, 19)
