Abstract

Abstract A pager receiver for a radio calling signal carrying a call number and/or a message includes a processing unit for producing a drive and an information signal to produce ordinary tone or tones related to the call number and to provide ordinary visual displays representative of the message, respectively. A processed signal is produced by the processing unit to provide extraordinary tones peculiar to a message-absent call, a message-present call, and a repeat call for repeatedly displaying a prior message. The processed signal also appears to provide extraordinary visual displays unique to the message-absent call. When the pager receiver has a plurality of preassigned call numbers, the processed signal is produced to provide such extraordinary displays inherent to each of the respective presassigned call numbers. In addition to the extraordinary displays of the preassigned call number, a plurality of messages are successively stored in a memory in a predetermined order to be successively displayed one by one. On reception of the repeat call, the predetermined order may be changed to keep the message related to the repeat call from being erasing from the memory even when the memory is full of message.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 156 words
A pager receiver having first and second preassigned call numbers preassigned thereto and responding to a present call signal carrying a call number to produce first and second audible signals when said call number of the present call signal is coincident with said first and second preassigned call numbers, respectively, said first and second preassigned call numbers being different from each other, said pager receiver comprising: a processing circuit responsive to said present call signal for processing said present call signal into first and second processed signals which are representative of first and second patterns, respectively, when the call number of said present call signal is coincident with said first and said second preassigned call numbers, respectively, said first and said second patterns being for specifying said first and said second preassigned call numbers, respectively; and display means responsive to said first and said second processed signals for selectively displaying said first and said second patterns.
Claim 2
Dependent Claim 156 words
A pager receiver having first and second preassigned call numbers preassigned thereto and responding to a present call signal carrying a call number to produce first and second audible signals when said call number of the present call signal is coincident with said first and second preassigned call numbers, respectively, said first and second preassigned call numbers being different from each other, said pager receiver comprising: a processing circuit responsive to said present call signal for processing said present call signal into first and second processed signals which are representative of first and second patterns, respectively, when the call number of said present call signal is coincident with said first and said second preassigned call numbers, respectively, said first and said second patterns being for specifying said first and said second preassigned call numbers, respectively; and display means responsive to said first and said second processed signals for selectively displaying said first and said second patterns.
