Abstract
Abstract An improved voice communication feature is disclosed for an untethered personal stylus used with a digitizing display in a pen-based computer system. A microphone and speaker are included in an untethered stylus in conjunction with a mechanical contact and radiative pickup mechanisms, to enable multimedia communication between the user and the pen-based computer system, through a digitizing display. <IMAGE>

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
In a data processing system, a multimedia stylus (20) for a digitizing display, comprising: a multiplexer (36) in said stylus, having an input coupled to a receiver for receiving data from said data processing system, and having an output coupled to a transmitter, for transmitting data to said data processing system; a position detector (38) in said stylus, coupled to an input of said multiplexer, for generating a position indicating signal from said digitizing display and in response, said multiplexer transmitting a first signal through said transmitter to said data processing system; a microphone (16) in said stylus, coupled to an input of said multiplexer, for converting an input audio signal of a first audio message into a second signal transmitted by said multiplexer through said transmitter to said data processing system; said data processing system sending to said receiver in said stylus third signal, in response to said first signal; a speaker (17) in said stylus coupled to an output of said multiplexer, for receiving said third signal representing a second audio message and producing an output audio signal in response to said first signal.
Claim 2
Dependent Claim
149 words
In a data processing system, a multimedia stylus for a digitizing display, comprising: a multiplexer in said stylus, having an input coupled to a receiver in said stylus for receiving data from said data processing system, and having an output coupled to a transmitter in said stylus for transmitting data to said data processing system; a radiative pickup antenna in said stylus, coupled to an input of said multiplexer, for receiving position indicating electromagnetic signals from said digitizing display and in response, said multiplexer transmitting first signals through said transmitter to said data processing system; said data processing system receiving said first signals and in response thereto, sending to said receiver in said stylus second signals representing a first audio message; a speaker in said stylus, coupled to an output of said multiplexer, for receiving said second signals and producing an output audio signal of said first audio message.
Claim 3
Dependent Claim
98 words
The system of claim 2, which further comprises: a microphone in said stylus, coupled through a switch means to an input of said multiplexer, for converting an input audio signal of a second audio message into third signals; said data processing system sending to said receiver in said stylus fourth signals, for controlling said switch means; said switch means selectively coupling said microphone to said transmitter through said multiplexer in response to said fourth signals; whereby said microphone is selectively coupled to said transmitter in response to said position indicating electromagnetic signals received by said radiative pickup antenna.
Claim 4
Dependent Claim
90 words
The system of claim 2, which further comprises: a mechanical contact sensor in said stylus, coupled to an input of said multiplexer, for generating contract indicating signals and in response, said multiplexer transmitting third signals through said transmitter to said data processing system; said data processing system receiving said third signals and in response thereto, sending to said receiver in said stylus fourth signals representing a second audio message; said speaker in said stylus receiving said fourth signals and producing a second output audio signal of said second audio message.
Claim 5
Dependent Claim
97 words
The system of claim 4, which further comprises: a microphone in said stylus, coupled through a switch means to an input of said multiplexer, for converting an input audio signal of a third audio message into fifth signals; said data processing system sending to said receiver in said stylus sixth signals, for controlling said switch means; said switch means selectively coupling said microphone to said transmitter through said multiplexer in response to said sixth signals; whereby said microphone is selectively coupled to said transmitter in response to said contact indicating signals generated by said mechanical contact sensor.
Claim 6
Dependent Claim
64 words
The system of claim 4, which further comprises: a microphone in said stylus, coupled through a switch means to an input of said multiplexer, for converting an input audio message into fifth signals; said switch means having a control input coupled to said mechanical contact sensor, for selectively coupling said microphone to said transmitter through said multiplexer in response to said contact indicating signals.
Claim 7
Dependent Claim
128 words
In a data processing system, a multimedia stylus for a digitizing display, comprising: a multiplexer in said stylus, having an input coupled to a receiver for receiving data from said data processing system, and having an output coupled to a transmitter, for transmitting data to said data processing system; a position detector in said stylus, coupled to an input of said multiplexer, for generating a position indicating signal from said digitizing display and in response, said multiplexer transmitting a first signal through said transmitter to said data processing system; an audio means in said stylus coupled to an output of said multiplexer, for receiving a second signal from said receiver; said data processing system receiving said first signal and in response thereto, sending said receiver said second signal.
Claim 8
Dependent Claim
39 words
The system of claim 7, which further comprises: said audio means is a speaker in said stylus, for receiving said second signal representing an audio message and producing an output audio signal in response to said position sensing signals.
Claim 9
Dependent Claim
69 words
The system of claim 7, which further comprises: said audio means is a microphone in said stylus, coupled through a switch means to an input of said multiplexer, said switch means being coupled to an output of said multiplexer, for selectively converting an input audio signal into a third signal; said switch means selectively coupling said microphone to said transmitter through said multiplexer in response to said second signal.
Claim 10
Dependent Claim
157 words
In a data processing system, a multimedia stylus for a digitizing display, comprising: a multiplexer in said stylus, having an input coupled to a receiver for receiving data from said data processing system, and having an output coupled to a transmitter, for transmitting data to said data processing system; a position detector in said stylus, coupled to an input of said multiplexer, for generating a position indicating signal from said digitizing display and in response, said multiplexer transmitting a first signal through said transmitter to said data processing system; a microphone in said stylus, coupled through a switch means to an input of said multiplexer, said switch means having a control input coupled to said position detector, for selectively transmitting an audio signal through said multiplexer and transmitter to said data processing system; said switch means selectively coupling said microphone to said transmitter through said multiplexer in response to said position indicating signal from said position detector.
Claim 11
Independent Claim
40 words
The system according to any one of the above claims, wherein said position detector is a radiative pickup antenna in said stylus, for receiving a position indicating electromagnetic signal from said digitizing display and in response, outputting said first signal.
