Digital voice storage mobile

Claim 2

A radio control terminal for the secondary stations in a multi-unit communications system for voice and data communications, having a primary station and a plurality of secondary stations each primary station adapted to transmit a command data packet including an address, and each secondary station including a microphone to permit input of voice messages by an operator, said control terminal comprising: digitizing means for digitizing a voice message; memory means for storing the digitized voice message; processing means for appending operator entered voice messages in the memory means to a message previously stored in the memory means; conversion means for converting digitized stored message to analog form; and, transmission means for transmitting of converted stored messages to the primary station.

Claim 3

The radio control terminal of claim 1 wherein said processing means activates transmission of a command data packet indicating an emergency status condition, and activates the conversion means and the transmission means to initiate transmission of a stored message in response to a command data packet transmitted by the primary station subsequent to transmission of the emergency status command data packet by the secondary station.

Claim 4

A radio control terminal for the secondary stations in a multi-unit communications system for voice and data communications, having a primary station and a plurality of secondary stations each primary station adapted to transmit a command data packet including an address, and each secondary station including a microphone to permit input of voice messages by an operator, said control terminal comprising: converting means for digitizing an analog voice message into a digitized equivalent voice message and for reconverting a digitized equivalent voice message into an analog voice message; memory means coupled to said converting means for storing a digitized equivalent voice message; means coupled to said converting means for reproducing an analog voice message from a reconverted, stored, digitized equivalent voice message; said converting means additionally enabling the playing of a stored digitized equivalent voice message in response to completion of storage thereof.

Claim 5

A radio control terminal for the secondary stations in a multi-unit communications system for voice and data communications, having a primary station and a plurality of secondary stations each primary station adapted to transmit a command data packet including an address, and each secondary station including a microphone to permit input of voice messages by an operator, said control terminal comprising: converting means for digitizing an analog voice message into a digitized equivalent voice message and for reconverting a digitized equivalent voice message into an analog voice message; memory means coupled to said converting means for storing a digitized equivalent voice message; means coupled to said converting means for reproducing an analog voice message from a reconverted, stored, digitized equivalent voice message; said converting means additionally enabling the playing of a stored digitized equivalent voice message in response to completion of storage thereof.

Claim 6

A radio control terminal for the secondary stations in a multi-unit communications system for voice and communications, having a primary station and a plurality of secondary stations each primary station adapted to transmit and receive both a command data packet including an address and voice message, and each secondary station including a microphone to permit input of voice messages by an operator, said control terminal comprising: means for receiving a command data packet from the primary station including a record command and an address corresponding to the predetermined station address of the respective secondary station; and, memory means for digitizing and storing voice messages transmitted to the secondary station by the primary station in response to said record command receipt.

Claim 7

A radio control terminal for the secondary stations in a multi-unit communications system for voice and communications, having a primary station and a plurality of secondary stations each primary station adapted to transmit and receive both a command data packet including an address and voice message, and each secondary station including a microphone to permit input of voice messages by an operator, said control terminal comprising: means for receiving a command data packet from the primary station including a record command and an address corresponding to the predetermined station address of the respective secondary station; and, memory means for digitizing and storing voice messages transmitted to the secondary station by the primary station in response to said record command receipt.

Claim 8

The radio control terminal of claim 4 wherein the memory means further comprises means for storing up to eight unique primary station transmitted messages.

Claim 9

The radio control terminal of claim 4 further comprising means for indicating that a message transmitted from the primary station has been stored but not played.
