Abstract
Abstract Method and apparatus for integrating the output of a measuring instrument, in which a plurality of check points of each peak in the output are detected to produce a time signal which lasts a predetermined period of time, so that if one of the check points is detected within the time period caused by the detection of the previous check point, the peak is treated as a noise peak. Whether or not a peak being detected is a noise peak superimposed on the signal peak of the measured output is determined by whether the end point or the apex of the peak exceeds a predetermined level.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
154 words
An apparatus for integrating the area of a peak in the output of a measuring instrument, and for eliminating the integration of unwanted noise peaks comprising: detection signal means for detecting predetermined check points including at least the start point, the apex and the end point of said peak to produce start point, apex and end point detection signals; time signal means operable in response to said detection signals to provide at least first, and second, time signals which last for predetermined first and second periods of time; integrating means operable in response to said start point detection signal to start integration of the output of said measuring instrument and in response to said end point detection signal to terminate said integration; and control means operable in response to said apex detection signal and said first time signal to reset said integrating means when said apex is detected during said first period of time.
Claim 2
Independent Claim
154 words
An apparatus for integrating the area of a peak in the output of a measuring instrument, and for eliminating the integration of unwanted noise peaks comprising: detection signal means for detecting predetermined check points including at least the start point, the apex and the end point of said peak to produce start point, apex and end point detection signals; time signal means operable in response to said detection signals to provide at least first, and second, time signals which last for predetermined first and second periods of time; integrating means operable in response to said start point detection signal to start integration of the output of said measuring instrument and in response to said end point detection signal to terminate said integration; and control means operable in response to said apex detection signal and said first time signal to reset said integrating means when said apex is detected during said first period of time.
Claim 3
Dependent Claim
29 words
The apparatus of claim 1, further including inhibit signal means for preventing the operation of said control means when said apex is detected during said second period of time.
Claim 4
Dependent Claim
62 words
The apparatus of claim 1 wherein said time signal means provides third and fourth time signals which last for a predetermined third and fourth period of time and further including a second control means operable in response to said end point detection signal and said first, third and fourth time signals, to prevent termination of said integrating operation of said integrating means.
Claim 5
Dependent Claim
52 words
The apparatus of claim 1, further including means for detecting the level of said output so that when said output exceeds a predetermined level the resetting operation of said control means is prevented, while when said output has become lower than said predetermined level, the operation of said integrating means is terminated.
Claim 6
Dependent Claim
21 words
The system of claim 4, further including means for printing the result of said integration when said integrating operation is terminated.
Claim 7
Dependent Claim
40 words
The apparatus of claim 1, further including means for detecting a predetermined point on said output having become lower than a predetermined level to produce a signal, and means operable in response to said last-mentioned signal to terminate said integration.
Claim 8
Dependent Claim
21 words
The apparatus of claim 6, wherein said predetermined point is selected from the apex and the end point of a peak.
Claim 9
Dependent Claim
73 words
The apparatus of claim 1, further including means for comparing the level of the end point of each peak in said output with that of a succeeding peak to produce an output when the level of the end point of a peak becomes higher than that of the previous peak which was lower than the level of the last peak, and means operable in response to said last-mentioned signal to terminate said integration.
Claim 10
Independent Claim
163 words
An apparatus for integrating the area of a peak in the output of a measuring instrument and for eliminating the integration of unwanted noise peaks, comprising: detection signal means for detecting predetermined check points including at least the start point, the apex and the end point of said peak to thereby produce start point, apex and end point detection signals; time signal means operable in response to said detection signals to produce first, second and third time signals which last for predetermined first, second and third periods of time; integrating means operable in response to said start point detection signal to start integration of the output of said measuring instrument and in response to said end point detection signal to stop said integration; and first control means for preventing the application of said end point detection signal to said integrating means when either the apex detection signal or the end point detection signal is produced during said first, secoNd or third time periods.
Claim 11
Independent Claim
163 words
An apparatus for integrating the area of a peak in the output of a measuring instrument and for eliminating the integration of unwanted noise peaks, comprising: detection signal means for detecting predetermined check points including at least the start point, the apex and the end point of said peak to thereby produce start point, apex and end point detection signals; time signal means operable in response to said detection signals to produce first, second and third time signals which last for predetermined first, second and third periods of time; integrating means operable in response to said start point detection signal to start integration of the output of said measuring instrument and in response to said end point detection signal to stop said integration; and first control means for preventing the application of said end point detection signal to said integrating means when either the apex detection signal or the end point detection signal is produced during said first, secoNd or third time periods.
Claim 12

31 words
The apparatus of claim 9 wherein said control means comprises gate means receiving said end point detection signal as an input and one of said time signals as an inhibit input.
Claim 13
Dependent Claim
41 words
The apparatus of claim 10 further including means for detecting the level of said output of said measuring instrument to prevent said inhibit input from being applied to said gate means when said output has become lower than a predetermined level.
Claim 14
Dependent Claim
49 words
The apparatus of claim 9 further including means connected to said integrating means, and means connecting said printing means to the output of said detection signal means to apply said start point detection to print out the result of said integration at the start point of a succeeding peak.
Claim 15
Dependent Claim
63 words
The apparatus of claim 11 wherein said time signal means produces a fourth time signal which lasts for a predetermined fourth period of time and further including second control means to prevent the application of said start point detection signal to said integrating means when said second control means receives said start point detection signal during said second, third or fourth time periods.
Claim 16
Dependent Claim
67 words
The apparatus of claim 9 further including means for comparing the level of the end point of each peak in said output with that of a succeeding peak to produce an output to be applied to said integrating means when the level of the end point of a peak becomes higher than that of the previous peak which was lower than the level of the last peak.
