Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
A portable communication system message receiving device comprising a communication receiver for detecting encoded signals transmitted over a communication channel, a battery, a decoder coupled to the battery and responsive to detected encoded signals from the receiver for processing the detected signals in real time, address memory coupled to and accessed by the decoder containing predetermined address information, and comparison means coupled to the decoder and the address memory for producing a control signal when the detected signals correlate with predetermined address information, and annunciation means coupled to the comparison means and responsive to the control signals for alerting the user of the reception of a message Characterised by: the receiving device further including an internal clock coupled to the decoder for establishing timing signals for real time processing of detected signals; and power conservation circuit responsive to the timing signals for reducing the power drain on the battery by temporarily disabling preselected functions of message receiving device independently of the detection of received signals.
Claim 2
Dependent Claim
165 words
A portable communication system message receiving device comprising a communication receiver for detecting encoded signals transmitted over a communication channel, a battery, a decoder coupled to the battery and responsive to detected encoded signals from the receiver for processing the detected signals in real time, address memory coupled to and accessed by the decoder containing predetermined address information, and comparison means coupled to the decoder and the address memory for producing a control signal when the detected signals correlate with predetermined address information, and annunciation means coupled to the comparison means and responsive to the control signals for alerting the user of the reception of a message Characterised by: the receiving device further including an internal clock coupled to the decoder for establishing timing signals for real time processing of detected signals; and power conservation circuit responsive to the timing signals for reducing the power drain on the battery by temporarily disabling preselected functions of message receiving device independently of the detection of received signals.
Claim 3
Dependent Claim
48 words
The receiving device of claim 1 wherein said decoder has two modes of operation, a first mode associated with full processing capability in real time with a corresponding power drain, and a second mode of operation associated with a diminished processing capability with a correspondingly diminished power drain.
Claim 4
Dependent Claim
36 words
The receiving device of claim 2 further including a DC to DC power converter coupled between the battery and the decoder to establish a power level to support the first mode of operation of the decoder.
Claim 5
Dependent Claim
25 words

Claim 9
Dependent Claim
33 words
The receiving device of claim 2 further including means for modifying the frequency of the time signals from the internal clock to establish the first and second modes of operation of said decoder.
Claim 10
Dependent Claim
31 words
The receiving device of claim 8 wherein said decoder further includes means responsive to the time signals for controlling operational functions for the decoder independently of the detection of encoded signals.
Claim 11
Dependent Claim
22 words
The receiving device of claim 9 wherein the, decoder includes means for controlling the electrical power between the battery and the receiver.
Claim 12
Dependent Claim
30 words
