First Claim
Patent Images
1. A pager capable of generating an alert signal and displaying a message received by said pager, comprising:
- a time message identifying circuit connected to receive said message and determine whether said message contains time data, said time message identifying circuit outputting a time data signal indicating that time data is present in said message and extracting said time date from said message;
a memory connected to receive and store said message as a realert message when said time message identifying circuit indicates that time data is present;
a display coupled to receive said time data signal and including a time data message portion for indicating to a user of said pager that said message includes time data in response to said time data signal;
a time comparing circuit coupled to said time message identifying circuit, said time comparing circuit comparing a current time with said time data extracted by said time message identifying circuit and calculating a time interval between said current time and a time indicated by said time data;
a counter connected to receive said time interval from said comparing circuit, said counter counting a period of time to produce a realert signal, said period of time being less than said time interval by a predetermined amount of time; and
realert means responsive to said realert signal for displaying said realert message stored in said memory and for generating an alert to said user.
