Abstract

A radio pager decoder including a register which is incremented when a page is received and a visual indicator which displays a count of the number of received pages. Pages may also be selectively retrieved from memory.

Claims

1. In a pager, a method of indicating a number of received pages comprising the steps of:

incrementing a register when a page is received; and

displaying a count from the register, which count is a measure of the number of received pages.

2. A pager including a receiver, means for decoding an address in a received page, and means for controlling functions, the pager comprising:

means for detecting a received page;

means for counting a number of detected received pages; and

means for displaying a measure of the count.

3. The apparatus of claim 2 wherein the means for counting comprises a plurality of flip-flops connected in cascade with a delayed trigger.

4. The apparatus of claim 3 comprising in addition means for selecting a desired one of the received pages.

5. In a pager including a page address decoder that produces a pulse in response to a received page, a circuit for indicating a number of received pages comprising:

a plurality of cascaded flip-flops connected to the page address decoder, receiving as an input the pulse from the page address decoder, and receiving as a clock input a delayed pulse from the page address decoder; and

a plurality of message indicators equal in number to the number of cascaded flip-flops, each one of the message indicators connected to a different one of the flip-flops of the cascaded flip-flops to indicate a number of flip-flops that have been triggered, which number is a measure of the number of received pages.

6. The circuit of claim 5 comprising in addition

a voltage source;

a read button connected to the voltage source;

a counter connected to the read button to count in response to an actuation of the read button;

a decoder connected to the counter to produce a signal on one of a plurality of lines according to the count in the counter; and

a plurality of indications, one connected to each of the lines to indicate the count in the counter;

which count is a measure of a number of actuations of the read button.

7. A paging receiver including a memory, comprising:

means for detecting a plurality of types of received pages;

means for determining which of said types of received pages has been received; and

means for counting a number of received pages of a particular type.

8. The paging receiver of claim 7, further including means for displaying a measure of the number of received pages of a particular type counted by said counting means.

9. The paging receiver of claim 8, wherein:

said detecting means includes means for detecting voice type received pages and means for detecting tone type received pages; and

said counting means includes means for counting the number of tone type received pages.

10. The paging receiver of claim 8, wherein:

said detecting means further includes means for detecting voice type received pages and means for detecting data type received pages; and

said counting means includes means for counting the number of data type pages.

11. The paging receiver of claim 7, further including:

a visual indicator, operatively coupled to said determining means, for indicating that a certain one of said types of pages has been received.

12. The paging receiver of claim 7, wherein said counting means includes means for assigning message numbers to received pages of said particular type so that said message number is indicative of the order of receipt of said particular type of received pages.
