Claims Analysis

Total Claims: 31
Claim 1
Independent Claim 76 words
A selective call receiver, comprising in combination: a receiver/demodulator for receiving and decoding selective call radio signals; means for manually selecting between an audible alert mode and a tactile alert mode; override means for detecting an alert mode override code as a part of said selective call radio signal and for overriding said manually selected alert mode in response thereto; and means for generating an alert in response to receipt of said alert mode override code.
Claim 2
Dependent Claim 23 words
The apparatus of claim 1, wherein said override means selects an audible alert mode in response to detecting said alert mode override code.
Claim 3
Dependent Claim 29 words
The apparatus of claim 1, further comprising a display, and wherein a "lost pager" message is displayed on said display in response to detecting said alert mode override code.
Claim 4
Dependent Claim 41 words
The apparatus of claim 1, wherein said means for generating an alert includes means for generating an alert sequence comprising repeating sequence of a first alert for a first time period followed by a second alert for a second time period.
Claim 5
Dependent Claim 33 words
The apparatus of claim 4, wherein said first alert includes an audible alert operating at a high audio level and wherein said second alert includes an audible alert at a lower audio level.
Claim 6
Dependent Claim 28 words
The apparatus of claim 4, wherein said first alert includes an audible alert operating at a high audio level and wherein said second alert includes audible chirp alert.
Claim 7
Dependent Claim 18 words
The apparatus of claim 4, wherein said first time period is short compared with said second time period.
Claim 8
Dependent Claim 12 words
The apparatus of claim 1, wherein said tactile alert includes a vibrator.
Claim 9
Dependent Claim 27 words
The apparatus of claim 1, further comprising resetting means for restoring said alert mode to said manually selected mode after receipt of said alert mode override code.
Claim 10
Dependent Claim 13 words
The apparatus of claim 9, wherein said resetting means includes a reset switch.
Claim 11
Dependent Claim 43 words
A selective call receiver, comprising in combination: a receiver/demodulator for receiving and decoding selective call radio signals; selecting means, responsive to an alert mode override code as a part of said selective call radio signal, for selecting an alert mode in response thereto.
Claim 12
Dependent Claim 23 words
The apparatus of claim 11, further comprising an alert mode switch which select between an audible alert mode and a tactile alert mode.
Claim 13
Dependent Claim 22 words
The apparatus of claim 11, further comprising means for generating an alert in response to receipt of said alert mode override code.
Claim 14
Dependent Claim 23 words
The apparatus of claim 11, wherein said selecting means selects an audible alert mode in response to detecting said alert mode override code.
Claim 15
Dependent Claim 28 words
The apparatus of claim 11, further comprising a display, and wherein a predetermined message is displayed on said display in response to detecting said alert mode override code.
Claim 16
Dependent Claim 42 words
The apparatus of claim 13, wherein said means for generating an alert includes means for generating an alert sequence comprising a repeating sequence of a first alert for a first time period followed by a second alert for a second time period.
Claim 17
Dependent Claim 33 words
The apparatus of claim 16, wherein said first alert includes an audible alert operating at a high audio level and wherein said second alert includes an audible alert at a lower audio level.
Claim 18
Dependent Claim 28 words
The apparatus of claim 16, wherein said first alert includes an audible alert operating at a high audio level and wherein said second alert includes audible chirp alert.
Claim 19
Dependent Claim 18 words
The apparatus of claim 16, wherein said first time period is short compared with said second time period.
Claim 20
Dependent Claim 13 words
The apparatus of claim 11, further comprising a tactile alert including a vibrator.
Claim 21
Independent Claim 44 words
A method for operation of a selective call radio receiver, comprising the steps of: detecting a selective call signal including a predetermined address; detecting an alert mode override code; and overriding a manually selected alert mode in response to said alert mode override code.
