Programmable multi-address pager receiver and method of characterizing same
First Claim
1. A method governing the operation of alert annunciation in response to decoded pager addresses from received pager signals, said method comprising the steps of:
- (a) decoding any one of a plurality of predetermined pager addresses from received pager signals;
(b) generating a first digital word having a code uniquely corresponding to one of said decoded pager addresses of step (a);
(c) decoding any one of a plurality of address functions associated with said decoded pager address from received pager signals;
(d) generating a second digital word having a code uniquely corresponding to one of said decoded address functions of step (c);
(e) selecting a subset of combined codes of said first and second digital words from a set of all coded first and second digital words by assigning a pattern code selected from a limited plurality of pattern codes to each member of said subset;
(f) generating an alert signal in response to the generated first digital word of step (b) and the generated second digital word of step (d) having a combined code which is a member of said subset with an annunciation pattern corresponding to the assigned pattern code thereof; and
(g) inhibiting alert signal generation in response to the generated first digital word of step (b) and the generated second digital word of step (d) having a combined code which is not a member of said subset.

Abstract
The pager receiver including a conventional address decoder, an alert envelope waveform generator, and an alert function mapper is disclosed. The pager is individually and uniquely characterized by programming the alert function mapper to govern the generation of assigned alert annunciation patterns by the waveform generator in response to selected decoded pager addresses and associated functions thereof, and to inhibit alert generation by the waveform generator in response to non-selected decoded pager addresses and associated functions thereof. In one embodiment, the alert signal waveform generator is enabled to respond to the alert function mapper only when the pager address is decoded by the decoder.

5. A multi-address pager receiver including a receiver section for receiving pager signals, said pager receiver comprising:
-
a decoder for decoding any one of a plurality of predetermined pager addresses from said received pager signals and generating a first digital word having a code uniquely corresponding to said decoded pager address of said plurality of predetermined pager addresses, and for decoding any one of a plurality of related predetermined address functions of said decoded pager address from said receiver pager signals and generating a second digital word having a code uniquely corresponding to said decoded address function of said plurality of address functions; means governed by a third digital word to generate an alert signal having an annunciation pattern corresponding to an assignment code of said third digital word, said means rendered non-responsive when governed by an inhibit code of said third digital word; and non-volatile memory means for coupling to said decoder and said alert signal generating means and including a plurality of registers, each register of said plurality being programmable to store a codedword representing one of either an assignment code of said third digital word or an inhibit code of said third digital word, the programmed code of each register of said plurality being uniquely accessible as a code of said third digital word by the code of the first and second digital words for governing the operation of the alert signal generating means, whereby a pager may be individually and uniquely characterized by the programming of the non-volatile memory means to generate assigned alert annunciation patterns in response to selected decoded pager addresses and associated functions thereof and to inhibit alert generation in response to non-selected decoded pager addresses and associated functions thereof. - View Dependent Claims (6, 7, 8)
