Patent number: 9016120Abstract: A method of determining a testing volume for a micronaire measurement by containing a fiber sample within a micronaire chamber having a length and at least one movable end wall. A flow is initiated along the length of the micronaire chamber. The fiber sample is compressed within the micronaire chamber by advancing the movable end wall, and the advancement of the movable end wall is stopped when at least one property of the flow attains a set point. The position of the movable end wall defines the testing volume. In this manner, there is provided a convenient method of setting a testing volume and acquiring the information needed to take a micronaire measurement.Type: GrantFiled: November 12, 2009Date of Patent: April 28, 2015Assignee: Uster Technologies AGInventors: James T. Wender, Preston S. Baxter, Hossein M. Ghorashi

Patent number: 8301410Abstract: A method for determining a corrected weight of a mixed volume, by gravimetrically measuring a total weight of the mixed volume, creating an image of the mixed volume, detecting at least one selected component within the image of the mixed volume, estimating a component weight of the at least one selected component from the image of the mixed volume, and subtracting the component weight from the total weight to yield the corrected weight.Type: GrantFiled: May 6, 2010Date of Patent: October 30, 2012Assignee: Uster Technologies AGInventors: Youe-Tsyr Chu, Preston S. Baxter, Michael E. Galyon, Hossein M. Ghorashi

Publication number: 20120158342Abstract: A method for measuring the weight of impurities in a mixed volume of fibers and impurities by mechanically separating the impurities are from the fibers, whereupon some undesired fibers still remain admixed to the impurities due to imperfections of the mechanical separation. A total weight of the separated impurities and the undesired fibers is gravimetrically measured. An image of the separated impurities and the undesired fibers is created. A weight of the undesired fibers is estimated from the image. The estimated weight of the undesired fibers is subtracted from the total weight to yield a corrected weight of the impurities. The mechanical separation and the subsequent electronic correction yield a more accurate weight of the impurities.Type: ApplicationFiled: May 5, 2011Publication date: June 21, 2012Applicant: USTER TECHNOLOGIES AGInventors: Youe-Tsyr Chu, Preston S.

Patent number: 8199319Abstract: A fiber instrument for measuring properties of a fiber sample, the fiber instrument having a surface for receiving the fiber sample, a hand for pressing the fiber sample against the surface, an illumination source for selectively illuminating the fiber sample with more than one peak wavelength, where each of the peak wavelengths is independently controllable as to an applied intensity of the peak wavelength, a sensor for capturing images of the fiber sample while it is illuminated, and a controller for controlling at least the sensor and the illumination source. By providing multiple peak wavelengths of illumination that are each independently controllable as to illumination intensity, the fiber instrument as described herein is better able to detect both foreign material within the fiber sample, and color gradations of the fiber sample.Type: GrantFiled: June 29, 2009Date of Patent: June 12, 2012Assignee: Uster Technologies AGInventors: Preston S. Baxter, Youe-Tsyr Chu, Hossein M. Ghorashi, Michael E. Galyon

Patent number: 7143642Abstract: A fiber testing station. Electrically conductive first fiber retaining means engage first ends of fibers, where the fibers extend in substantially one direction from the first fiber retaining means to distal second ends of the retained fibers. The first fiber retaining means are electrically isolated from the fiber testing station. First length measurement means measure first relaxed lengths of the retained fibers between the first fiber retaining means and the second ends of the retained fibers. Electrically conductive second fiber retaining means engage the second ends of the retained fibers. The second fiber retaining means are electrically isolated from the fiber testing station. Moisture measurement means take electrical measurements along the retained fibers between the first fiber retaining means and the second fiber retaining means, and thereby determine a moisture content of the retained fibers.Type: GrantFiled: July 1, 2005Date of Patent: December 5, 2006Assignee: Uster Technologies, Inc.Inventors: Preston S.
