Abstract
Abstract A method of and arrangement for the production of a control signal for automatically operated devices, wherein the control signal is derived from a digital value to be measured repeatedly, which comprises the steps of forming the individual difference signals between an actual measured digital value and a reference value of each individual measurement, and storing the individual difference signals. The individual difference signals are each compared with settable limit values representing statistical variations of the measured value and representing erroneous measurements and material faults of the goods to be measured. A control signal is emitted upon surpassing of the limit value for the statistical variation by an individual difference signal, to a regulating unit control of the control device, and the individual difference signals are cancelled and the emittance of a control signal suppressed upon surpassing another limit value repressing the erroneous measurements and material faults.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
146 words
A method for the production of a control signal for automatically operated devices, wherein said control signal is derived from successive digital values to be measured at repeated times, comprising the steps of repeatedly forming the individual difference signal between an actual measured digital value and a reference value of each individual measurement, storing said individual difference signals, comparing each of said individual difference signals with a settable first limit value representing statistical variations of the measured values and representing erroneous measurings and material faults of the goods to be measured, emitting a control signal, upon surpassing of the limit value for the statistical variations by an individual difference signal, to a regulating unit control of a control device, and cancelling said individual difference signals and suppressing the emittance of said control signal upon surpassing a second limit value representing said erroneous measurings or material faults.
Claim 2
Independent Claim
146 words
A method for the production of a control signal for automatically operated devices, wherein said control signal is derived from successive digital values to be measured at repeated times, comprising the steps of repeatedly forming the individual difference signal between an actual measured digital value and a reference value of each individual measurement, storing said individual difference signals, comparing each of said individual difference signals with a settable first limit value representing statistical variations of the measured values and representing erroneous measurings and material faults of the goods to be measured, emitting a control signal, upon surpassing of the limit value for the statistical variations by an individual difference signal, to a regulating unit control of a control device, and cancelling said individual difference signals and suppressing the emittance of said control signal upon surpassing a second limit value representing said erroneous measurings or material faults.
Claim 3
Dependent Claim
55 words
The method, as set forth in claim 1, which includes the step of deducting an individual difference signal from all individual difference signals occurring within a measuring delay time period forming subtracted signals for prevention of a multiple consideration of a difference of a measured value from said reference value within the measuring delay time.
Claim 4
Dependent Claim
28 words
The method, as set forth in claim 2, which includes the step of storing said already considered individual difference signal in a reduction accumulator during said delay time.
Claim 5
Dependent Claim
21 words
The method, as set forth in claim 1, which includes the step of stopping the consideration of further individual difference signals.
Claim 6
Dependent Claim
34 words
The method, as set forth in claim 4, which includes the step of emitting an additional control signal upon occurring of an individual difference signal of reversed polarity surpassing said settable first limit value.
Claim 7
Dependent Claim
41 words
The method, as set forth in claim 1, which includes the steps of storing the number of surpassings of said second limit value representing said erroneous measurings or material faults, and actuating a means upon surpassing of said second limit value.
Claim 8
Dependent Claim
46 words
The method, as set forth in claim 2, which includes the steps of adding said subtracted signals and storing same over a summing time period, comparing said added signals with a settable third limit value, and emitting control signals upon surpassing of said third limit value.

28 words
The method, as set forth in claim 7, which includes the step of modifying said added signals according to a predetermined function of the number of added measurings.
