Abstract: The apparatus is for measuring at least one of color and trash in a fiber sample. A light emitting diode light source generates an incident light that is directed toward the fiber sample, and reflected by the fiber sample, thereby producing a reflected light. A sensor receives the reflected light and produces a signal. A controller controls the light source and the sensor, and at least one of receives and adjusts the signal. At least one of the incident light, the reflected light and the signal is conditioned to compensate for differences between the light emitting diode light source and a xenon light source. Thus, drawbacks of the xenon light source used to date can be avoided.

A radiation subsystem (114) comprises a radiation source (120) for directing a first, ultraviolet radiation (122) and a second, visible radiation (123) toward the sample (106), and causing the sample (106) to produce a fluorescent radiation (124) and a reflected radiation (125). A sensing subsystem (126) comprises an imager (130) for capturing the fluorescent radiation (124) and the reflected radiation (125) in an array of pixels (408). A control subsystem (132) comprises a processor (136) for controlling the presentation subsystem (102), the radiation subsystem (114), and the sensing subsystem (126), and for creating a fluorescent and reflected radiation image (400) containing both spectral information and spatial information in regard to the fluorescent radiation (124) and the reflected radiation (125).

Abstract: An apparatus (100) for measuring not only the reflected radiation but also the fluorescence emission of a textile sample (106), which includes a presentation subsystem (102) having a viewing window (108). A radiation subsystem (114) has a tunable radiation source (120) for directing a desired radiation (122) having a wavelength range and an intensity through the viewing window (108) toward the sample (106), and thereby causing the sample (106) to produce a fluorescence (124). A sensing subsystem (126) has an imager (130) for capturing the reflected radiation and fluorescence (124) in an array of pixels. A control subsystem (132) has a processor (136) for controlling the presentation subsystem (102), the radiation subsystem (114), and the sensing subsystem (126), and creates a reflected radiation and fluorescence image containing both spectral information and spatial information in regard to the reflected radiation and fluorescence (124) of the sample (106).

Abstract: The weighing apparatus is for automatically weighing trash that is separated from a fiber sample. It includes a scale, a weigh pan disposed on the scale, a cleaner for passing a cleaning element across a surface of the weigh pan when the scale is not taking a weight measurement, and a controller for selectively controlling operations and sequencing of the scale and the cleaner.

Abstract: An instrument for identifying at least one of fiber blend composition and fiber blend ratio in an input material moved by a third set of fiber movements. A second spectral radiation source directs radiation toward the input material. A second spectral sensor receives portions of the second radiation that pass through the input material. A third spectral sensor receives portions of the second radiation that reflect off of the input material. A controller processes the signals from at least one of the second spectral sensor and the third spectral sensor to determine at least one of the fiber blend composition and the fiber blend ratio in the input material. The controller also sends control signals to the second electromagnetic radiation source and the third set of fiber movements.
