Abstract

A paging receiver is described having page memory for automatically storing a page if the user does not reset the receiver within a prescribed time interval after an alert signal is started. After a page is stored it can be recalled from page memory by operating the reset button.

Independent Claims | See all claims (14)

  1. 1. In an alerting device that is responsive to a calling signal to initiate an alerting signal and having reset means to terminate the alerting signal, means including time interval measuring means responsive to said calling signal to initiate said alerting signal, said time interval measuring means including means automatically to terminate said alerting signal after a prescribed time interval, said reset means having alternatively a normal reset state and a recall state into which said reset means can be set, an input for setting said reset means alternatively into said reset state or said recall state, said reset means having operator means, a reset output means and recall output means, means coupling said reset means via said reset output means to said time interval measuring means for terminating operation of the latter and thereby terminating said alerting signal if said operator means is operated when said reset means is in said reset state, means coupling said reset means via said recall output means to said time interval measuring means for initiating a time interval measuring cycle thereof and thereby initiating said alerting signal if said operator means is operated when said reset means is in said recall state, alerting signal memory means that is settable into a stored-page state, said time interval measuring means including means for setting said alerting signal memory means in said stored-page-state upon automatically terminating said alerting signal in the absence of operation of said operator means of said reset means during the time when the latter is in said reset state, said alerting signal memory means being coupled to said reset means via said input thereof for setting said reset means into said recall state when said alerting signal memory means is set into said stored-paged state.
  2. 9. An altering device responsive to a calling signal for providing calling information to a user comprising, in combination, means responsive to the calling signal to provide an alerting signal during a predetermined time interval, memory means for storing said calling information, means responsive to said calling signal to set said memory means into an information-storage state, means operable within said time interval to terminate the alerting signal and the information storage state of the memory means, said means operable after the end of said time interval, in the absence of operation of said means within said time interval, to recall said calling information from said memory means.
  3. 12. An alerting device responsive to a calling signal for providing calling information to a user, including, in combination,means responsive to the calling signal to provide an alerting signal having a predetermined time interval;memory means for storing said calling information;operator means having first and second modes of operation and being operable in the first mode of operation during the predetermined time interval to terminate the alerting signal;said memory means responsive to the nonoperation of said operator means during the predetermined time interval for automatically storing said calling information in the memory means and for setting the operator means into the second mode of operation; andthe operator means being operable in the second mode of operation to recall the calling information from the memory means.
  4. 14.14. An alerting device responsive to an encoded calling signal for providing calling information to a user, comprising:means responsive to the encoded calling signal for decoding the calling signal to provide a decoded signal;alert means responsive to the decoded signal for providing an alert signal having a predetermined duration;operator means having first and second modes of operation and being operable in the first mode of operation during the duration of the alert signal for terminating the alert signal;the alert signal providing means being automatically responsive to non-operation of the operator means during the duration of the alert signal to provide a memory alert signal upon end of duration of the alert signal;memory means having a non-stored page state, and a stored page state for storing the calling information;calling signal memory means responsive to the decoded signal for setting the memory means to a non-stored page state wherein the memory means is responsive to the memory alert signal for setting the memory means into the stored page state and for setting the operator means into the second mode of operation;the operator means in the second mode of operation being operable to provide an alert enable signal; andthe alert means being responsive to the alert enable signal to provide the alert signal.
