Abstract
Abstract In a selective call radio paging device, a plurality of alerts are generated in response to the decoding of a message having an address corresponding to the address assigned to the pager. A specific alert envelope waveform is generated and drives an alerting device of a first type (e.g., a transducer). Inverting means is provided to invert the envelope and cause a second alerting device (e.g., visual) to be activated in a manner complementary to the first. Thus, alerting devices are not operated concurrently, and peak loads on a resident power source are avoided.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
150 words
An alert generating apparatus for use in conjunction with a selective call receiver having an address decoder that matches a received address recovered from an input signal to an address assigned to the selective call receiver and generates at least one function detect signal corresponding to an alert sequence, said apparatus comprising: first means for generating a first alert signal selected in response to the function detect signal received from the address decoder; second means for generating a second alert signal selected in response to the function detect signal received from the address decoder; and means for alternatingly presenting at least a selected two of an audible alert signal, a visual alert signal, and a tactile alert signal as determined at least in part by the received address and controlled by the first and second alert signals, thereby producing the alert sequence and reducing the load on the energy source.
Claim 2
Dependent Claim
150 words
An alert generating apparatus for use in conjunction with a selective call receiver having an address decoder that matches a received address recovered from an input signal to an address assigned to the selective call receiver and generates at least one function detect signal corresponding to an alert sequence, said apparatus comprising: first means for generating a first alert signal selected in response to the function detect signal received from the address decoder; second means for generating a second alert signal selected in response to the function detect signal received from the address decoder; and means for alternatingly presenting at least a selected two of an audible alert signal, a visual alert signal, and a tactile alert signal as determined at least in part by the received address and controlled by the first and second alert signals, thereby producing the alert sequence and reducing the load on the energy source.
Claim 3
Dependent Claim
43 words
An apparatus according to claim 1 wherein said first means comprises: envelope generating means for producing a modulating signal; a source of an energizing signal; and third means for modulating said energizing signal with said modulating signal to produce said first alert signal.
Claim 4
Dependent Claim
29 words
An apparatus according to claim 2 wherein said second means comprises first inverting means having an input coupled to said envelope generating means and responsive to said modulating signal.
Claim 5
Dependent Claim
14 words
An apparatus according to claim 2 wherein said modulating means is an AND gate.
Claim 6
Dependent Claim
27 words
An apparatus according to claim 2 wherein said envelope generating means is capable of generating a plurality of different modulating signals each having a different predetermined pattern.
Claim 7
Dependent Claim
18 words
An apparatus according to claim 1 wherein said first means comprises envelope generating means for producing a signal.
Claim 8
Dependent Claim
27 words
An apparatus according to claim 6 wherein said second means comprises inverting means having an input coupled to said envelope generating means and responsive to said signal.
Claim 9
Dependent Claim
216 words
An alert generating apparatus for use in conjunction with a selective call receiver having an address decoder that matches a received address recovered from an input signal to an address assigned to the selective call receiver and generates at least one function detect signal corresponding to an alert sequence, said apparatus comprising: first means for generating a first alert signal selected in response to the function detect signal received from the address decoder; second means for generating a second alert signal selected in response to the function detect signal received from the address decoder; and means for alternatingly presenting at least a selected two of an audible alert signal, a visual alert signal, and a tactile alert signal as determined at least in part by the received address and controlled by the first and second alert signals, a first of the at least a selected two alert signals being activated during at least a first portion of each of a plurality of successive time intervals and a second of the at least a selected two alert signals being activated during at least a second portion of each of a plurality of successive time intervals, the second portion being subsequent to the first portion, thereby producing the alert sequence and reducing the load on the energy source.
Claim 10
Dependent Claim
216 words
An alert generating apparatus for use in conjunction with a selective call receiver having an address decoder that matches a received address recovered from an input signal to an address assigned to the selective call receiver and generates at least one function detect signal corresponding to an alert sequence, said apparatus comprising: first means for generating a first alert signal selected in response to the function detect signal received from the address decoder; second means for generating a second alert signal selected in response to the function detect signal received from the address decoder; and means for alternatingly presenting at least a selected two of an audible alert signal, a visual alert signal, and a tactile alert signal as determined at least in part by the received address and controlled by the first and second alert signals, a first of the at least a selected two alert signals being activated during at least a first portion of each of a plurality of successive time intervals and a second of the at least a selected two alert signals being activated during at least a second portion of each of a plurality of successive time intervals, the second portion being subsequent to the first portion, thereby producing the alert sequence and reducing the load on the energy source.
