Rechargeable, untethered electronic stylus for computer with interactive display screen
First Claim
1. A pen based computer comprising:
- a) a housing supporting computer electronics and including a stylus support;
b) a visible interactive display screen assembly supported by the housing, the display screen assembly including a sensing assembly; and
c) an untethered, rechargeable stylus for inputting data to the computer electronics via positioning the stylus with respect to images displayed on the display screen assembly, the stylus including;
i) a stylus case adapted to be removably secured to the workslate computer housing stylus support, the stylus case supporting stylus electronics and a rechargeable power source;
ii) the stylus electronics including a signal generator for generating a signal received by the sensing assembly and correlated to a position of the stylus with respect to the display screen assembly by the sensing assembly;
iii) the rechargeable power source coupled to the stylus electronics; and
iv) a first conductor and a spaced apart second conductor, the first and second conductors electrically coupled to a negative terminal and a positive terminal respectively of the rechargeable power source to provide a conductive path for recharging the power source, the conductors being accessible from an exterior of the stylus case; and
v) wherein the stylus case is generally cylindrically shaped and includes a first end and a spaced apart second end and the first conductor comprises a concave shaped conductive member forming a part of the case adjacent the case second end.

Abstract
A pen based workslate computer having a detachable, rechargeable stylus is disclosed. The workslate computer includes a housing supporting computer electronics and a stylus charging station defining an opening adapted to receive the detachable stylus. The housing also supports a visible interactive display screen assembly including a sensing assembly. Depending on the position of actuators of the stylus, signal generation circuitry of the stylus generates one of a plurality of signals having different frequencies. The generated signal is received by the sensing assembly and correlated with a position of the stylus with respect to the display screen assembly by the sensing assembly thereby allowing data and/or commands to be input by an operator manipulating a signal generation end of the stylus to "pick" icons or other representations displayed on a LCD screen. When the stylus is inserted in the charging station opening it is held in place by a clamping mechanism and charging circuitry of the charging station recharges a rechargeable power source of the stylus.
