Abstract
Abstract A simultaneous translation system used to enable interpretation from the language of a speaker into several different languages. A switching system and matrix circuit are used to connect the speaker to appropriate interpretation booths thereby enabling an interpreter to translate the speaker''s language into the different appropriate language and a circuit for transmitting the speaker''s language and the language of each active interpreter to a conference audience.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
126 words
A simultaneous translation system comprising a first transmission circuit for transmitting an input audio-signal from a master microphone to a transmitter, booths to which the audiosignal is transmitted, a first switch for switching an input audio-signal from an auxiliary microphone in each booth to a second switch means, and a second transmission circuit for selecting either said input audio-signal from said master microphone or said input audio-signal from the auxiliary microphone by said second switch means and transmitting it to the transmitter, the system being characterized by said second switch means worked by a voltage applied on the horizontal line of a selective circuit connected to a hold-cancel circuit and said first switch worked by a voltage applied on the vertical line of the selective circuit.
Claim 2
Dependent Claim
126 words
A simultaneous translation system comprising a first transmission circuit for transmitting an input audio-signal from a master microphone to a transmitter, booths to which the audiosignal is transmitted, a first switch for switching an input audio-signal from an auxiliary microphone in each booth to a second switch means, and a second transmission circuit for selecting either said input audio-signal from said master microphone or said input audio-signal from the auxiliary microphone by said second switch means and transmitting it to the transmitter, the system being characterized by said second switch means worked by a voltage applied on the horizontal line of a selective circuit connected to a hold-cancel circuit and said first switch worked by a voltage applied on the vertical line of the selective circuit.
Claim 3
Dependent Claim
126 words
A simultaneous translation system comprising a first transmission circuit for transmitting an input audio-signal from a master microphone to a transmitter, booths to which the audio-signal is transmitted, a first switch for switching an input audio-signal from an auxiliary microphone in each booth to a second switch means, and a second transmission circuit for selecting either said input audio-signal from said master microphone or said input audio-signal from the auxiliary microphone by said second switch means and transmitting it to the transmitter, the system being characterized by said second switch means worked by a voltage applied on the horizontal line of a selective circuit connected to a hold-cancel circuit and said first switch worked by a voltage applied on the vertical line of the selective circuit.
