Remote typing system

Claim 2

A remote typing station, for connection to an information storage and retrieval system having means for storing and transmitting analog information defining audio messages and receiving digital data defining a transcription for the audio messages, comprising: (a) computer means for mutually exclusively initiating and terminating audio and data modes, said data mode being terminated when said audio mode is initiated and said data mode being initiated when said audio mode is terminated; (b) interface means connected to said computer means, said interface means configured to receive audio information signals representing an audio message and transmit digital data signals; (c) terminal means having a keyboard and display, said terminal means connected to said computer means and said interface means, said terminal means generating digital data signals representing the audio information signals of the audio message received by said interface means whereby the digital data signals constitute transcribed audio information; and (d) switch means connected to said computer means, said switch means having energized and deenergized states, said computer means initiating said audio mode for transmitting a control signal to said information storage and retrieval system when said switch means is in one of said energized and denergized states, said computer means terminating said audio mode and initiating said data mode for transmitting a further control signal to said information storage and retreival system when said switch means is in the other of said energized and deenergized states.

Claim 3

The remote typing station as claimed in claim 1 wherein said computer means includes a central processing unit, a read-only memory and a random access memory, said central processing unit generating command signals for controlling operation of said remote typing station, said read-only memory storing system programs and said random access memory storing transcribed audio information.

Claim 4

The remote typing station as claimed in claim 2 further comprising terminal interface means for converting parallel data to serial data and serial data to parallel data, said computer means using parallel data and said terminal means using serial data.

Claim 5

The remote typing station as claimed in claim 2 wherein said switch means is a foot pedal.

Claim 6

In combination with an information storage and retrieval system having means for storing and transmitting analog information defining audio messages and receiving digital data defining a transcription of the audio messages, a remote typing station communicating with the information storage and retrieval system via a single telephone line, said remote typing station comprising: (a) computer means for mutually exclusively initiating and terminating audio and data modes, said data mode being terminated when said audio mode is initiated and said data mode being initiated when said audio mode is terminated; (b) interface means connected to said single telephone line and said computer means, said interface means configured to receive the audio information transmitted by the information storage and retrieval system and to transmit digital data signals defining the transcribed audio information to the information storage and retrieval system with both the audio information signals and digital data signals being transmitted via the single telephone line; (c) terminal means having a keyboard and display, said terminal means connected to said computer means and said interface means, said terminal means generating the digital data defining the transcribed audio information; and (d) switch means connected to said computer means, said switch means having energized and deenergized states, said computer means initiating said audio mode and transmitting a control signal to said information storage and retrieval system when said switch means is in one of said energized and deenergized states, said computer means terminating said audio mode and initiating said data mode and transmitting a further control signal to said information storage and retrieval system when said switch means is in the other of said energized and deenergized states.

Claim 7

In combination with an information storage and retrieval system having means for storing and transmitting analog information defining audio messages and receiving digital data defining a transcription of the audio messages, a remote typing station communicating with the information storage and retrieval system via a single telephone line, said remote typing station comprising: (a) computer means for mutually exclusively initiating and terminating audio and data modes, said data mode being terminated when said audio mode is initiated and said data mode being initiated when said audio mode is terminated; (b) interface means connected to said single telephone line and said computer means, said interface means configured to receive the audio information transmitted by the information storage and retrieval system and to transmit digital data signals defining the transcribed audio information to the information storage and retrieval system with both the audio information signals and digital data signals being transmitted via the single telephone line; (c) terminal means having a keyboard and display, said terminal means connected to said computer means and said interface means, said terminal means generating the digital data defining the transcribed audio information; and (d) switch means connected to said computer means, said switch means having energized and deenergized states, said computer means initiating said audio mode and transmitting a control signal to said information storage and retrieval system when said switch means is in one of said energized and deenergized states, said computer means terminating said audio mode and initiating said data mode and transmitting a further control signal to said information storage and retrieval system when said switch means is in the other of said energized and deenergized states.

Claim 8

The remote typing station as claimed in claim 5 wherein said computer means includes a central processing unit, a read-only memory and a random access memory, said central processing unit generating command signals for controlling operation of said remote typing station and transmission of the audio information and digital data between the remote typing station and information storage and retrieval system, said read-only memory storing system programs and said random access memory storing transcribed audio information.

Claim 9

The remote typing station as claimed in claim 6 further comprising terminal interface means for converting parallel data to serial data and serial data to parallel data, said computer means using parallel data and said terminal means using serial data.

Claim 10

The remote typing station as claimed in claim 5 wherein said switch means is a foot pedal.

Claim 11

The remote typing station as claimed in claim 8 wherein said foot pedal is in said energized state when depressed and in said deenergized state when released.

Claim 12

The remote typing station as claimed in claim 8 wherein said foot pedal is a depressable dual switch pedal having forward and reverse energized states when said foot pedal is depressed, said audio mode initiated when said foot pedal is in one of said forward and reverse energized states.
