Abstract

Abstract An electronic system for the transmission of binary coded pulse information is comprised of a transmitter and a receiver. The transmitter is provided with circuitry for the generation of a pre-signal pulse which is produced upon the actuation of respective command inputs. The pre-signal pulse is combined with and transmitted a fixed period ahead of the pulses representing the command information. The receiver is provided with a pre-amplifier stage having an inherently fixed response time, such that receipt of the pre-signal pulse prepares the pre-amplifier for handling of the coded information without a loss of information resulting from distortion during the initial response time of the pre-amplifier.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 137 words
An electronic data transmission system for transmission of pulse coded information having a transmitter means and a receiver means, said system comprising: a plurality of manually actuatable command input means; a pulse generator actuated by any of said command input means for producing information pulses representing commands according to selected inputs; a means for producing a pre-signal pulse simultaneously with actuation of any input command; a means for combining said pre-signal pulse and said information pulses such that a pre-signal pulse associated with respective pulse information is transmitted prior to said information to said receiver means; and an amplifier in said receiver means having a fixed response time, whereby said amplifier is activated by said pre-signal pulse so that said response time has elapsed prior to introduction into said amplifier of pulse information associated with said pre-signal.
Claim 2
Dependent Claim 137 words
An electronic data transmission system for transmission of pulse coded information having a transmitter means and a receiver means, said system comprising: a plurality of manually actuatable command input means; a pulse generator actuated by any of said command input means for producing information pulses representing commands according to selected inputs; a means for producing a pre-signal pulse simultaneously with actuation of any input command; a means for combining said pre-signal pulse and said information pulses such that a pre-signal pulse associated with respective pulse information is transmitted prior to said information to said receiver means; and an amplifier in said receiver means having a fixed response time, whereby said amplifier is activated by said pre-signal pulse so that said response time has elapsed prior to introduction into said amplifier of pulse information associated with said pre-signal.
Claim 3
Dependent Claim 39 words
The electronic data transmission system of claim 1 wherein the means for combining said pre-signal and said information pulses includes a delay switch to delay transmission of said pulse information until a fixed time after production of said pre-signal.
Claim 4
Dependent Claim 31 words
The electronic data transmission system of claim 2 wherein the delayed pulse information and the pre-signal each comprise an input to an OR-gate having its output connected to said transmitter means.
Claim 5
Dependent Claim 41 words
The electronic data transmission system of claim 1 wherein said receiver means further comprises a programmable decoder connected to an output of said amplifier for interpreting received pulse information and directing said information to designated addresses in accordance with a program.
