Two-way communication device with transmission of stored signal directly initiated by user
First Claim
1. A circuit for use in a two-way communication device of a communication system, said circuit comprising:
- a sensor adapted to receive a message provided by a user;
an analog-to-digital (A-D) converter coupled to said sensor, said A-D converter being operative to output a digital signal dependent on said message provided by said user;
a memory operative to store data;
a control circuit coupled to said memory and to said A-D converter, said control circuit operative to access said memory; and
a transmitter coupled to said control circuit, said transmitter operative to transmit an electromagnetic signal;
wherein said circuit is operative to store said digital signal in said memory; and
wherein said circuit is further operative to transmit an electromagnetic signal dependent on said stored digital signal when directly initiated by said user, said user directly initiating transmission of the electromagnetic signal after said digital signal is stored, said user thus having an opportunity to review said message before transmission.

Abstract
A circuit for use in a two-way pager of a paging system to transmit voice messages. The circuit includes: a microphone to receive an analog audio signal provided by a user; an analog-to-digital (A-D) converter coupled to the microphone; a memory; a processor coupled to the memory and to the A-D converter; and a transmitter coupled to the processor. The analog audio signals are typically voice messages spoken by the user, which the A-D converter samples and digitizes. The processor stores the digitized voice message in the memory. The user can then transmit the stored digitized voice message through the transmitter, which is processed through the paging system and provided to the intended recipient. In a further refinement, the circuit includes a playback circuit that allows the user to listen to the stored digitized voice message before transmitting the voice message to the rest of the paging system.

32. A method for transmitting messages from a two-way communication device in a communication system, the method comprising:
-
storing a message in the two-way communication device provided by a user;
including a telephone number of a recipient in said message; and
transmitting said message to said recipient through a switch of said communication system, said user directly initiating said transmitting of said message after storing said message in the two-way communication device, said user thus having an opportunity to review said message before transmission. - View Dependent Claims (33, 34)
