Abstract: Disclosed is a method for controlling surface errors of a sample in a homogeneity measurement of infrared optical materials. In this invention, a calculation relationship among the surface errors, measurement principles and precision requirements is established. The wavefront distortion caused by the surface errors of the sample measured in infrared wavebands is converted to the surface errors of the sample which is processed and inspected under the visible light. Through establishing related algorithms and formulas for numerical calculations, a numerical table for controlling the surface errors of the sample is created to ensure the precision of the homogeneity measurement for the infrared optical material under short, middle and long wavebands. A case table for controlling the surface errors of the sample is also provided to ensure the precision of the homogeneity measurement for the specific infrared optical materials under short, middle and long wavebands.

Abstract: Multiple groups of sensors are circumferentially spaced apart at each cross-directional position along a sensing roll of a nip press to measure and cancel or nearly cancel the effects of rotational variability which may be acting on the sensing roll. The strategically-placed sensors are designed to measure the pressure being placed against the web that is being advanced through the nip press. The average of the measurements of multiple sensors spaced circumferential apart provides a good cancellation of any rotational variability that might be found at a cross-directional position on the sensing roll. In this manner, a more true measurement of the nip pressure profile can be obtained and better adjustments made to reduce nip pressure profile variability. In addition, the nip variability profile may be used as a predictor of cover or bearing failures, resonant frequencies and other roll anomalies.

Abstract: A mixed-reality system causes a magnetic transmission device to transmit a magnetic field signal. The mixed-reality system also causes a magnetic-field sensing device to determine a measurement of the magnetic field signal. The mixed-reality system then identifies, using one or more input devices, that a magnetically-interfering object is located within a same environment as both the magnetic transmission device and the magnetic-field sensing device. The mixed-reality system also determines one or more characteristics of magnetic field interference that the magnetically-interfering object is imparting on the magnetic transmission device or the magnetic-field sensing device. The mixed-reality system then computes an adjustment to a pose-estimation model based upon the one or more characteristics of magnetic field interference. The pose-estimation model is used to calculate a pose of at least one of the magnetic transmission device or the magnetic-field sensing device.
