Abstract

Abstract Two groups of terminals are interconnected by circuitry which transfers a pulse from any one terminal of the first group to all terminals of the second group and vice versa. Each terminal is connected to a common transfer system through an individual amplifier circuit which permits simultaneous bidirectional pulse transfers. The amplifiers are arranged to inhibit transfers of signals from one terminal of a group to the remaining terminals of the same group.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 180 words
A pulse transfer system comprising: a plurality of amplifiers, each said amplifier including a common input/output terminal, a first input lead, a first output lead, means for generating an output signal on said first output lead in response to an input signal on said common input/output terminal, means for generating an output signal on said common input/output terminal in response to an input signal on said first input lead, and means for inhibiting the transfer of pulses from said first output lead to said common input/output terminal; first means connecting all of said first output leads of a first group of the amplifiers to all of said first input leads of a second group of the amplifiers; and second means connecting all of said first output leads of said second group of the amplifiers to all of said first input leads of said first group of the amplifiers; whereby an input pulse applied to a common input/output terminal of one group of amplifiers causes the generation of output pulses on all common input/output terminals of the other group of amplifiers.
Claim 2
Dependent Claim 180 words
A pulse transfer system comprising: a plurality of amplifiers, each said amplifier including a common input/output terminal, a first input lead, a first output lead, means for generating an output signal on said first output lead in response to an input signal on said common input/output terminal, means for generating an output signal on said common input/output terminal in response to an input signal on said first input lead, and means for inhibiting the transfer of pulses from said first output lead to said common input/output terminal; first means connecting all of said first output leads of a first group of the amplifiers to all of said first input leads of a second group of the amplifiers; and second means connecting all of said first output leads of said second group of the amplifiers to all of said first input leads of said first group of the amplifiers; whereby an input pulse applied to a common input/output terminal of one group of amplifiers causes the generation of output pulses on all common input/output terminals of the other group of amplifiers.
Claim 3
Dependent Claim 73 words
A pulse transfer system as claimed in claim 1 wherein: said first output leads of said first group of the amplifiers are connected to said first input leads of said second group of the amplifiers through a first single transfer lead; and said first output leads of said second group of the amplifiers are connected to said first input leads of said first group of the amplifiers through a second single transfer lead.
Claim 4
Dependent Claim 44 words
A pulse transfer system as claimed in claim 1 in which each said amplifier is a bidirectional amplifier capable of transferring signals from said common input/output terminal to said first output lead and from said first input lead to said common input/output terminal simultaneously.
Claim 5
Dependent Claim 44 words
A pulse transfer system as claimed in claim 2 in which each said amplifier is a bidirectional amplifier capable of transferring signals from said common input/output terminal to said first output lead and from said first input lead to said common input/output terminal simultaneously.
Claim 6
Dependent Claim 53 words
A pulse transfer system as claimed in claim 1 including error detection means connected to said first output leads, said error detection means including means for generating an error indication signal in response to the simultaneous reception of input pulses by more than one common input/output terminal of the amplifiers in a group.
