Abstract
Abstract A printing apparatus for multiple signal printout has separate multiplexers for analog and pulse channels. The multiplexed analog signal is digitized, formatted, and applied via a selector to an adder, alternatively and selectively, the pulses are applied as digital signals to the adder. The adder receives zero offset numbers which differ for the different channels and the resultant numbers are applied to a one-out-of-n decoder driving printing electrodes. The system is under control of a cyclically addressed ROM whose outputs controls the multiplexing and furnishes the offset numbers. A clock sequencer times each acquisition frame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
209 words
Recording device for recording a plurality of different input signals provided in a corresponding plurality of different channels, comprising a multiplexing means for sequentially scanning said input channels to obtain a cyclically repeated acquisition of said input signals; an analog-to-digital conversion means having its input connected to an output of the multiplexing means for association with all of the channels of the plurality which provide analog signals, to obtain digitization thereof and to provide a train of digital signals; means for providing signals representing fixed numbers, defining individual zero scale levels for recording the digitized input signals; an adder connected for receiving the digital signals from the multiplexing means and as digitized and said fixed numbers to obtain an added output; means connected to multiplexing means and the means for providing, to operate them in synchronism with each other; a one-out-of-n decoder connected to the adder for receiving the output thereof, n being an integer, the decoder having n output channels accordingly; a plurality of altogether n- recording means respectively connected to the n output channels of the decoder for being individually operated by the decoder output channels; and a recording medium moving relative to the recording means to obtain print dots upon operation of the respective recording means.
Claim 2
Dependent Claim
209 words
Recording device for recording a plurality of different input signals provided in a corresponding plurality of different channels, comprising a multiplexing means for sequentially scanning said input channels to obtain a cyclically repeated acquisition of said input signals; an analog-to-digital conversion means having its input connected to an output of the multiplexing means for association with all of the channels of the plurality which provide analog signals, to obtain digitization thereof and to provide a train of digital signals; means for providing signals representing fixed numbers, defining individual zero scale levels for recording the digitized input signals; an adder connected for receiving the digital signals from the multiplexing means and as digitized and said fixed numbers to obtain an added output; means connected to multiplexing means and the means for providing, to operate them in synchronism with each other; a one-out-of-n decoder connected to the adder for receiving the output thereof, n being an integer, the decoder having n output channels accordingly; a plurality of altogether n- recording means respectively connected to the n output channels of the decoder for being individually operated by the decoder output channels; and a recording medium moving relative to the recording means to obtain print dots upon operation of the respective recording means.
Claim 3
Dependent Claim
56 words
Recording device as in claim 1, wherein the multiplexing means includes separate multiplexers for analog channels and for pulse signal channels, the conversion means being connected to the multiplexer for the analog channels, the multiplexing means further including selection means to selectively apply the multiplexed channels or the output of the conversion means to the adder.
Claim 4
Dependent Claim
39 words
Recording device as in claim 1, and including program means for controlling the multiplexing means to obtain interrogation of all said input channels in cyclic repetition, said program means further providing the fixed numbers in the sequence of multiplexing.
Claim 5
Dependent Claim
76 words
Recording device as in claim 3, including a recycling program counter and an addressable memory connected for being accessed by the counter to obtain sequential readout of information in accordance with the operation and as accessed by the counter, each such information including control information for operating the multiplexing means and one of the fixed numbers; and timing means for sequentially applying the information as read from memory to the multiplexing means and to the adder.
Claim 6
Dependent Claim
59 words
A recording device as in claim 4, said memory including an output bus for distributing the content of a readout memory location upon being accessed by the counter, to the multiplexing means and to the adder, the programs means including timing means to cause sequential operation of the multiplexing means of the conversion means, and of the recording means.
Claim 7
Dependent Claim
26 words
A recording device as in claim 1, including a buffer interposed between the adder and the decoder to obtain a timed delay between acquisition and printing.
Claim 8
Dependent Claim
50 words
The recording device as in claim 1, wherein said n dot recording means is comprised of a plurality of n electrodes arranged in a row, the recording medium being a metallized strip, and means for applying a voltage between the respective energized electrode and the metallized strip to obtain printing.
Claim 9
Dependent Claim
36 words
A recording device as in claim 1 and including an exchangeable formatting circuit dividing the scale of the number defined by the conversion means for adapting the range to a particular portion of the recording medium.
