Yarn Quality Patents (Class 700/144)
  • Patent number: 10119210
    Abstract: A textile machine adjustment method is provided. An operating speed of a textile machine within an operating range is set by a processor according to the basic information of the fabric. A motion image of the fabric and the vibration characteristics of the yarns are recorded by a video camera. The operating speed of the textile machine is adjusted at least once, and the vibration characteristics of the yarns is analyzed after each adjustment of the operating speed. Multiple correlation factor functions and the relative weights of the multiple factors related to the operating speed of the textile machine are recorded. The relative weights of the multiple factors are adjusted according to a yield quality of the fabric. When an expected value is met, the fabric continues to be produced at the current operating speed; otherwise, the relative weights of multiple factors are adjusted to correct the operating speed.

  • Patent number: 9811110
    Abstract: A system and a method of sampling an event signal using multiple clocking signals each provided in a separate candidate clock domain each of which also receives points in time from a master clock. From each candidate clock domain, clocked by the individual clocking signals, pairs of a received point in time and event signal value are fed to a master clock domain. In the master clock domain, the values of the event signal may be determined over time as a function of master clock time. This may be used for synchronizing operation in the master clock domain of e.g. packet time stamping with an overall time defined by the event signal. Using multiple clocking signals for the sampling, a much more precise sampling of the event signal is facilitated.

  • Patent number: 8959002
    Abstract: Readings of a characteristic of the yarn along the longitudinal direction of the yarn are detected. Values of a yarn parameter are determined from the readings. An event field contains a quadrant of a two-dimensional Cartesian coordinate system, whose abscissa defines an extension of yarn parameter values in the longitudinal direction and whose ordinate defines a deviation of the yarn parameter from a desired value. Densities of events in the event field are determined from the values of the yarn parameter and their extensions in the longitudinal direction. A yarn body is represented as an area in the event field. The area on the one hand is delimited by the abscissa, on the other hand by the ordinate and further by a line in the event field that substantially follows a constant event density. The representation of the yarn body permits a clearing limit to be defined in a rapid and rational manner.

  • Patent number: 7996483
    Abstract: Adaptive caching techniques are described. In an implementation, a head end defines a plurality of cache periods having associated criteria. Request data for content is obtained and utilized to associate the content with the defined cache periods based on a comparison of the request data with the associated criteria. Then, the content is cached at the head end for the associated cache period.

  • Patent number: 6922604
    Abstract: The invention relates to a process and a device for adjusting clearing limits, defects in the yarn being cut out and a clearing limit separating defects which are to be cut out from defects which are not to be cut out. To achieve an improved, simplified and rapid adjustment of the clearing limit so the effect thereof in the end product can also be predicted more accurately, starting from the clearing limit, displays of defects in the end product are to be produced which make an effect of the defects in the end product visible.

  • Patent number: 6842532
    Abstract: A method of three dimensional measurement, evaluation, and grading system for fabric/textile structure/garment appearance, based an values P and Q, is carried out using a fixed digital camera positioned above a piece of the fabric, shining at least two different parallel light beams from inclined directions onto the surface of the fabric and capturing different reflected images of the surface with the camera. The captured images are analysed to derive certain parameters relevant to the appearance. In particular, values of P+Q may be used in a grading evaluation, where P and Q are summations of the surface gradients for a plurality of evenly distributed points in an x direction and in a y direction of the surface, respectively.

  • Patent number: 6263257
    Abstract: A device for the simulation of spinning machines with a view to their optimum economic use and operation. Starting from material properties of a preproduct (1) determined by measurement, as well as from configuration and setting parameters (3) of such a spinning machine, material properties (2) of the intermediate or output products which are being produced, which properties can be determined by measurement, are predicted using a process model describing the behavior of the spinning machine, by a simulation device. The process model on which a method being based is presented by a neural network. The coefficients determining the actual behavior of this neural network area calculated from a set of sample data in a training phase. This sample data and/or from otherwise conclusively predicted properties of the behavior of such a spinning machine.
