First Claim
Patent Images
1. A computing system comprising:
- a stylus configured for emitting a signal, the stylus including;
at least one battery; and
a switch operative to turn transmission of the signal ON/OFF,wherein the switch is operable to turn OFF transmission responsive to sensing that the stylus is in a reclined position indicating that the stylus is not in use;
a flat panel display;
a digitizer sensor overlaid on the flat panel display and operative to sense the signal emitted by the stylus, the digitizer sensor providing output;
a host computer operative to control display on the flat panel display and to receive the output provided by the digitizer sensor; and
a stylus garage configured for storing the stylus while not being used for interacting with the digitizer sensor and for recharging the at least one battery of the stylus while the stylus is stored in the garage.

Abstract
A pressure sensitive stylus, comprises a movable tip that recedes within a housing of the stylus in response to user applied contact pressure, wherein a displacement of the tip along an axis on which it recedes is a function of the applied contact pressure, and an optical sensor enclosed within the housing for optically sensing the displacement of the tip and for providing output in response to the sensing.
