Abstract: Controlling processes comprising detecting and measuring a parameter, for example presence and location of an element of a good, with at least two determinations as representations of the target parameter, transmitting signals to the computer, and processing the signals to compare the parameter to acceptable conditions. The detection can include three or more replications, optionally each for at least two parameters, optionally using at least two different methods to analyze the signals. The invention contemplates detecting and analyzing the target parameters using two or more analytical tools within the respective image to detect a given component of the product, namely two or more measurements of the parameter on a single visual image.

Abstract: Methods of controlling processes having operating conditions, one or more inputs, and one or more outputs. The methods comprise defining acceptable steady state conditions, operating the process, and sampling output on the basis of a dual segment output population model, detecting destabilizing process events which result in output not representing acceptable output parameters, defining operating conditions according to which output is rejected, and defining output parameters according to which output is rejected. Upon detecting a destabilizing process event, the invention temporarily implements sampling assuming a second segment of the output population.

Abstract: Methods of controlling manufacturing processes manufacturing, for example, absorbent articles. A target parameter to be measured is established, as are acceptable conditions of the target parameter. The target parameter is detected with first and second replications of determinations of the condition of the goods using multiple independent determinors, for example multiple sensors, or multiple replications using a common determinator, for example software instructions for analyzing a full digital vision image. Multiple determinations are taken at sites which are selected for their prospects for indicating acceptable conditions of the parameter. The method includes developing a measurement strategy, programming a computer to use appropriate analysis tools to evaluate the determination signals, transmitting the signals to the computer, and processing the signals according to an appropriate method.

Abstract: This invention pertains to fabricating composite personal care article products on a fabrication line, and sensing assembly quality characteristics of such personal care article products so fabricated, using infrared image sensing apparatus, and signal processing apparatus for processing the infrared energy so sensed, to fabricate visual displays of the composite images sensed by the infrared sensing apparatus. By using infrared imagery, and sensing the various temperatures of elements being placed and worked on the fabrication line, elements of the personal care articles which are hidden from visual observation can be sensed by sensing the infrared radiation emitted from such articles. Elements which are available for visual observation can likewise be sensed where temperature of such elements is suitable for detection, by infrared-sensitive receptors.

Abstract: A distinctive apparatus and method for selectively providing predetermined segments of web material comprises a supplying mechanism for providing the web material. A first sensing mechanism detects a reference marker on the web material to generate at least one reference marker datum which is associated with a selected web segment. A separating mechanism includes a sensor mechanism for providing at least one separation datum, and divides the web material along a separation region during a production of the web segment. A phase regulating mechanism controls a relative phasing between the reference marker detected by the first sensing mechanism and the dividing by the separating mechanism. The phasing is conducted with respect to a set reference value.

Abstract: The present invention provides an apparatus for examining a moving web composed of an interconnected plurality of articles to determine a location of a selected component thereof. The apparatus includes an indicating mechanism for providing marker data corresponding to the presence of a selected article. A metering mechanism generates gauge data corresponding to selected incremental lengths along the article in the movement direction of the web. A designating mechanism provides reference data corresponding to a selected reference point on the article, and a locating mechanism detects position data corresponding to a position of a selected component of the article. An evaluating mechanism processes the reference data, location data and gauge data to determine a spaced distance between the component and the reference point.
