Abstract
Abstract A selective call system is provided in which string searching or text matching operations are performed on data from data generating devices such as condition sensors in a security system. When a predetermined string is identified, an address of a selective call receiver such as a pager is generated and that receiver is called. The invention is applicable to other applications where data is generated which includes predetermined character strings.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
A selective call system comprising: means for receiving a predetermined plurality of characters; string searching means for monitoring said received plurality of characters including; means for storing a plurality of predetermined character strings, each character string of said plurality including at least one instructional character; and means for comparing sequentially the plurality of predetermined character strings of said storing means with said received predetermined plurality of characters to identify a predetermined character string of said plurality which correlates with the received characters; control means responsive tot he identified predetermined character string for selectively generating an address of a selective call receiver and message based on said identified predetermined character string and said at least one instructional character thereof; and transmitting means responsive to the control means for transmitting said selectively generated address and message to the selective call receiver identified by that address.
Claim 2
Dependent Claim
143 words
A selective call system comprising: means for receiving a predetermined plurality of characters; string searching means for monitoring said received plurality of characters including; means for storing a plurality of predetermined character strings, each character string of said plurality including at least one instructional character; and means for comparing sequentially the plurality of predetermined character strings of said storing means with said received predetermined plurality of characters to identify a predetermined character string of said plurality which correlates with the received characters; control means responsive tot he identified predetermined character string for selectively generating an address of a selective call receiver and message based on said identified predetermined character string and said at least one instructional character thereof; and transmitting means responsive to the control means for transmitting said selectively generated address and message to the selective call receiver identified by that address.
Claim 3
Dependent Claim
62 words
The selective call system of claim 1, further comprising character storage means for storing the received predetermined plurality of characters, and selector means for selecting at least one character from the stores plurality of received characters for message transmission to the selective call receiver, the at least one character selected being dependent on the instructional character of the predetermined character string identified.
Claim 4
Dependent Claim
53 words
The system of claim 2 including means for storing a plurality of operational codes; and means for selecting an operational code from said string means based on the identified character string; and wherein the selector means includes means for selecting characters from the received plurality of characters based on the selected operational code.
Claim 5
Dependent Claim
63 words
The system of claim 1, further comprising text storage means for prestoring predetermined text messages, and selector means for selecting a text message from the prestoring means based on the identified character string for transmission to the selective call receiver together with at least one character selected from the received plurality of characters based on the instructional character of the identified character string.
Claim 6
Dependent Claim
54 words
The system of claim 1, further comprising means for obtaining a numerical character from the received plurality of characters based on the identified character string and the instructional character thereof and means for calculating the address to which a message is to be sent, by combining the obtained numerical character with a fixed address.
Claim 7
Dependent Claim
58 words
The system of claim 5 wherein the identified character string includes a plurality of instructional characters; including means for designating an instructional character of the identified character string; and wherein the obtaining means includes means for obtaining the numerical character of the received plurality of characters which correlates with the designated instructional character of the identified character string.
Claim 8
Dependent Claim
41 words
The system of claim 1, further comprising means for connecting the system to one or more telephone receivers, means for dialing one or more telephone numbers and means for storing and sending an audible message to the telephone receiver so dialed.
Claim 9
Independent Claim
126 words
A method of operating a selective call system comprising the steps of: receiving a predetermined plurality of characters; monitoring said received plurality of characters by performing string searching operations thereon including: storing a plurality of predetermined character strings, each character string of said plurality including at least one instructional character; and comparing sequentially the plurality of predetermined character strings of said storing means with said received predetermined plurality of characters to identify a predetermined character string of said plurality which correlates with the received characters; generating an address of a selective call receiver and message based on said identified predetermined character string and said at least one instructional character thereof; and transmitting the generated address and message to the selective call receiver identified by that address.
Claim 10
Independent Claim
126 words
A method of operating a selective call system comprising the steps of: receiving a predetermined plurality of characters; monitoring said received plurality of characters by performing string searching operations thereon including: storing a plurality of predetermined character strings, each character string of said plurality including at least one instructional character; and comparing sequentially the plurality of predetermined character strings of said storing means with said received predetermined plurality of characters to identify a predetermined character string of said plurality which correlates with the received characters; generating an address of a selective call receiver and message based on said identified predetermined character string and said at least one instructional character thereof; and transmitting the generated address and message to the selective call receiver identified by that address.
