摘要： 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.

摘要： An apparatus for measuring a moisture content value within a volume. A frequency generator generates at least one source signal at frequencies of no more than about one kilohertz. Probes are disposed with surfaces in physical contact with the volume, where no direct current flows between the probes through the volume. One of the probes is electrically connected to the frequency generator as a source probe, and adapted to receive the source signal and emit the source signal into the volume, thereby creating an electrical field having characteristics that are dependent at least in part on a moisture content of the volume. Another of the probes operates as a receiver probe for sensing the electrical field and producing an output signal having an output property that is dependent at least in part on the source signal and the moisture content within the volume. Means are provided for producing a moisture content value for the volume, where the moisture content value is based at least in part on the output property of the output signal.

摘要： A gin process control system including sensing stations for sensing the physical properties of cotton as it progresses through a gin. A moisture sensor determines, over a wide range of values, the amount of moisture in the cotton. A quality monitor determines the color of the cotton, color distribution, and the amount and type of trash or other impurities which may be entrained in the cotton. A micronaire unit determines both micronaire and cotton maturity. A fiber length tester provides information on the length distribution, breaking strength, and elongation of the cotton fibers. Cotton samples are gathered from the gin flow stream and presented to the sensing stations in a variety of manual, semi-automated, and automated fashions. In a fully automated unit, the sensing stations are connected directly to the gin. The sensing stations are also in communication with the gin process control system, which uses the data from the sensing stations to automatically control the operation of the gin. Alternately, the sensing stations are assembled into a stand-alone unit. In a semi-automatic version of the stand-alone unit, samples are manually gathered and presented to the unit in cassettes for automated subsampling and testing by the sensing stations. In this semi-automatic version, the sensing stations may be in a configuration identical to that of the fully automatic, on-line unit. In a manual version of the stand-alone unit, the samples are manually gathered and manually placed into contact with the various sensing stations. The information reported by the stand-alone units can be used to manually control the operation of the gin.

摘要： An apparatus measures moisture content of cotton based upon rates of electrical charges flowing through the cotton. The apparatus includes a moisture sensor having first electrodes, second electrodes, and ground electrodes which are interdigitated between the first and second electrodes. The apparatus also includes a moisture content determination circuit that provides first electrical charges to the first electrodes, and second electrical charges to the second electrodes. The moisture content determination circuit determines the rate of electrical charge flowing from each of the first and second electrodes through the cotton to the ground electrodes, and determines the moisture content of the cotton based upon the rates of electrical charges flowing through the cotton. By thus applying first electrical charges to the first electrodes and second electrical charges to the second electrodes, the apparatus accurately measures the moisture content of the cotton over a wide range of moisture contents. This wide range is achieved by setting the first electrical charges on the first electrodes to a level which is optimal for moisture levels at the upper end of the desired measurement range, and by setting the second electrical charges on the second electrodes to a level which is optimal for moisture levels at the lower end of the desired measurement range.
