Abstract

A paging receiver demodulates a carrier wave modulated with a paging signal code and a plurality of information key codes, respectively. The demodulated information key codes are decoded by a receiver when its own paging signal code is detected. The receiver contains a plurality of words corresponding to said information key codes, respectively. These stored words are read out when they correspond to the decoded information. The read-out codes are then displayed.

Claims

1. A paging receiver comprising:

first means for receiving and demodulating a carrier wave modulated with at least a paging signal code assigned to the receiver, and a plurality of information key codes corresponding to a plurality of words, respectively;

second means responsive to a detection of said paging signal code for decoding said information key codes;

third mean for storing in advance a plurality of words individually corresponding to said information key codes, respectively;

fourth means for reading out of said third means those words which correspond to the decoded information key codes; and

fifth means for displaying the read-out words in a sentence form.

2. A paging receiver claimed in claim 1, comprising sixth means for providing an alert tone when its own paging signal code is detected.

3. A paging receiver claimed in claim 1 or 2, comprising means responsive to a control signal for scrolling said read-out words.

4. A radio paging system station comprising means in said station for storing a plurality of different specific information items;

means at said station responsive to the receipt of incoming signals having a calling signal and a plurality of information identifying key codes for detecting when said calling signal is assigned to said station;

means in the station identified by said calling signal and responsive to the detection of said calling signal for selecting the specific information items which are stored in said station and are identified by said key codes; and

means for converting said selected specific information item into a humanly recognizable communication form, said converting means comprising means for giving an individual voice message responsive to each identified stored information, and means responsive to said plurality of information key codes for assembling a plurality of said voice message into a spoken sentence.

5. The station of claim 4 and an alphanumerical display means associated with said station, said stored specific information items including signals required to read out alphanumerical signals in the form of words which may be displayed by said display means and may be read by a human who is viewing said displaying means, and means responsive to said incoming signals for scrolling a plurality of said words onto said display means in order to convey a sentence of words selected from among said stored signals.

6. The station of either one of the claims 5 or 4 and read only memory means for storing the specific information items as signals required to generate a read out in human communication terms, means for selectively addressing said read only memory at any storage location to read out a selected information item, and means responsive to said addresses for generating said human communication terms responsive to signals read out of said read only memory means.

7. The station of either one of the claims 5 or 4 and means responsive to said incoming signals for synchronizing said incoming signals.

8. The station of either one of the claims 5 or 4 and means responsive to said incoming signals for controlling the application of power to said station, said power application being either a battery saving mode of low power consumption during stand-by periods or a full power mode for powering said station to an operational level during a signal reception and a response thereto.

9. The station of claim 8 wherein said incoming signals include an alert signal for switching said power application from said standy-by battery saving mode to said full power operational level.

10. The station of claim 9 and timer means for returning said power application from said full power operational level to said battery saving stand-by mode if said station does not detect its address in the incoming code.
