Appeal No. 1998-0631
Application 07/957,990
withdrawn from consideration by Appellant pursuant to a
restriction requirement. Claims 11, 13, and 193-205 have
been canceled.
We affirm-in-part.
BACKGROUND
The disclosed invention relates to a keyboard that
generates signals indicative of key actuation and of the
pressure with which the user has pressed the keys. If the
pressure exceeds a certain threshold, or a certain average
pressure, the key event is annunciated. By warning the user
if too much pressure is being employed, injuries such as
carpal tunnel syndrome, tendonitis, and repetitive motion
syndrome can be avoided.
Claim 1 is reproduced below.
1. A keyboard apparatus comprising:
a keyboard with depressible keys;
means mechanically engaged with the keys and responsive
to the pressing of the keys for generating electrical
key signals indicative thereof;
output means conveying the key signals externally from
the keyboard;
pressure sensing means mechanically engaged with the
keys and responsive to pressure upon particular ones of
the keys for generating electrical pressure signals
