Abstract
Abstract Automatically controlled, discrete sampling of co-related values of two or more variables is triggered in response to at least two of the variables each time any of them reaches or passes predetermined values. The predetermined values are preferably equidistant and may be defined by one or more preceding samples. At the time of each sampling, the particular variable which has triggered the sampling is determined. An apparatus used to practice the method comprises means for triggering sampling of the variables when any of two or more of them is subjected to a predetermined variation in its magnitude, and the apparatus further includes means for supplying the sampled values to indicating, recording, or appropriate controlling means.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
105 words
A method for automatically controlling the discrete sampling of co-related amplitude values of an unknown function of at least two variables comprising the steps of establishing a number of predetermined values Associated with each of said variables respectively and defining amplitude limits within which each of said at least two variables may vary individually without triggering sampling of the other of said variables, causing either of said variables upon reaching or surpassing the amplitude of each of its associated predetermined values to trigger sampling of the instantaneous amplitude value of the other of said variables, and supplying said sampled amplitude values to data receiving means.
Claim 2
Independent Claim
105 words
A method for automatically controlling the discrete sampling of co-related amplitude values of an unknown function of at least two variables comprising the steps of establishing a number of predetermined values Associated with each of said variables respectively and defining amplitude limits within which each of said at least two variables may vary individually without triggering sampling of the other of said variables, causing either of said variables upon reaching or surpassing the amplitude of each of its associated predetermined values to trigger sampling of the instantaneous amplitude value of the other of said variables, and supplying said sampled amplitude values to data receiving means.
Claim 3
Dependent Claim
12 words
The method of claim 1 wherein said predetermined values are equidistantly spaced.
Claim 4
Dependent Claim
20 words
The method of claim 1 wherein the magnitudes of said predetermined values are determined by at least one preceding sampling.
Claim 5
Dependent Claim
30 words
The method of claim 1 wherein one of said two variables comprises a regularly spaced time function, and the other of said two variables comprises a parameter other than time.
Claim 6
Dependent Claim
21 words
