Abstract: Multiple two-dimensional variation patterns are extracted from two-dimensional sheet measurement data of sheet material being manufactured with the variation patterns being classified to identify the causes of the extracted patterns. The extracted two-dimensional variation patterns are identified with the elements or components of the process or machine which caused the patterns. The machine components which cause the variation patterns can then be adjusted and/or controlled so that the patterns can be reduced or substantially eliminated in sheets of material produced by the machine. In addition to adjustment and/or control of the process or machine producing the sheet of material, the extracted variation patterns can be used as new representations of sheet quality, process or machine quality and the patterns will provide more in-depth understanding for operators of the machine.

Abstract: A method and apparatus are provided for sensing basis weight of a rod (100) of material, such as tobacco, by two basis weight sensing operations which are then combined. A first sensing operation having high accuracy but slow response time is combined with a second sensing operation having low accuracy but fast response time to result in a high accuracy and fast response time output signal. The first sensing operation is performed using a low radiation beta gauge (102) which does not require licensing or safety precautions required by currently used beta gauges. The second sensing operation is performed using a dielectric sensor (104). The output signals from the first and second sensing operations are time averaged and combined such that the fast response output signals from the second sensing operation are calibrated or biased using the output signals from the first sensing operation to result in a high accuracy and fast response time measurement of the basis weight for a rod (100) of material, such as tobacco.

Abstract: A paper web (102) is monitored for measurement and manufacturing control by a stationary web sensor (132) extending across the entire web which is raster scanned by the motion of the web (102). Massive amounts of data are processed by a look up table memory addressed by digitized sensor data and the output from a reference memory containing element specific information. The lookup table is loaded with data to define a characteristic or property of the web corresponding (102) to digitized sensor data interpreted in view of element specific data from the reference memory. Rapidly processed data is stored in a memory in a form facilitating its display and interpretation by an operator of the web manufacturing machine (100) and also control of the machine. By controlling operation of the machine, uniformity of the web is substantially improved and, by taking the measurements closely adjacent the initial processing end of the web, corrections of nonuniformity in the web are quickly effected. To measure and control absolute characteristics and properties of the web, a second, preferably stationary, sensor (210) adjacent the finished end of the web (102) monitors the web adjacent a takeup reel (124). Alternately, for basis weight measurement and control, the weight of the takeup reel (124) is monitored and combined with the web width and machine operating speed to determine an absolute web basis weight. Thus, uniformity of the web and absolute values of characteristics and properties of the web can be measured and controlled.

Abstract: A plurality of random probing sequences are used to perturb a corresponding plurality of CD actuators of a web manufacturing machine. The web of sheet material is measured as the CD actuators are perturbed. The global process MD dynamics is estimated and a CD response is estimated for each of the plurality of CD actuators using the plurality of random probing sequences, measurements of the web of sheet material and the estimated global process MD dynamics. The estimated global process MD dynamics and the estimated CD responses form 2D responses for the plurality of CD actuators. To refine the 2D responses, the estimates of global process MD dynamics, and CD responses for each of the plurality of CD actuators are iterated. The actuator dynamics of the plurality of CD actuators may also be estimated and used in the estimates of the global process MD dynamics of the plurality of CD actuators and CD responses for each of the plurality of CD actuators. Variations that are not associated with actuator responses are removed from the estimated CD responses, for example by filtering. The estimated CD responses may be further refined by selecting one of the CD responses as a reference response. All remaining CD responses are shifted into alignment with the reference response to determine relative CD response locations and to define a group of overlapping CD responses. Using iterative techniques, a mean response is determined from a group of overlapping CD responses and variation bounds are set above and below the mean response. A family of probable CD responses are generated within the variation bounds and a most probable response is selected from the family of probable responses for each CD actuator response. The CD response for each CD actuator is replaced with the most probable response shifted by an appropriate amount for each CD actuator and multiplied by an optimal gain.

Abstract: A detector (110) of a measuring system (100) sensitive to light energy receives light (108) from a process (102) being measured and also from a separate light source (116) which is modulated such that it can be detected in signals generated by the detector (110). The separate light source (116) is turned on and off to modulate its output such that output signals from the detector (110) can be separated into on-times and off-times of the separate light source. The difference in on and off signal levels generated by the detector (110), or elements (110e) of the detector if the detector has a plurality of elements, are used to calibrate the detector (110). The light energy is conveyed to the detector (110) by an energy conduit which may be a "leaky" optical fiber (126) which receives light at one end and leaks the light out one sidewall along a portion of the fiber which is positioned adjacent to and preferably secured to the detector (110). The leaky optical fiber can be made by removing cladding (126c) from at least a portion of the sidewall along the portion of the fiber which is to leak light to the detector. Alternately, a bundle of fiber optics can be utilized with one end of the bundle receiving light and the other end being broken out to direct one or more of the fibers toward elements of the detector.

Abstract: A standard control signal for a web forming machine is temporarily interrupted and replaced by a perturbing signal or signals which are applied to one, a grouping, or all of a series of actuation cells of the web forming machine. One or more actuation cells are driven with an alternating perturbing signal(s) which generate a corresponding action in the actuation cell(s). The perturbing signal(s) alternates from a neutral position of the cell and is selected to minimize mean effects over any given period of time. The effects of the alternating signal(s) on the web appear within the area of the web which is affected by the actuation cell(s) such that the mapping and the response of the actuation cell(s) can be determined by monitoring that portion of the web which is formed while the alternating signal(s) is applied to the actuation cell(s). The mapping(s) and/or response(s) of the actuation cell(s) are obtained by correlating the perturbing signal(s) and a web property signal or profile signal obtained by monitoring the web formed by the machine. The perturbing signal(s) is defined by a pseudo-random binary sequence with multiple signals being selected to be statistically independent of one another. To ensure that the web is not perturbed beyond defined specifications, the perturbing signal preferably is gradually increased in amplitude and is terminated individually for each actuation cell upon reaching a usable amplitude.
