摘要： An ellipsometric apparatus provides two impinging focused probe beams directed to reflect off the sample along two mutually distinct and preferably substantially perpendicular directions. A rotating stage rotates sections of the wafer into the travel area defined by two linear axes of two perpendicularly oriented linear stages. As a result, an entire wafer is accessed for measurement with the linear stages having a travel range of only half the wafer diameter. The reduced linear travel results in a small travel envelope occupied by the wafer and, consequently, a small footprint of the apparatus. The use of two perpendicularly directed probe beams permits measurement of periodic structures along a preferred direction while permitting the use of a reduced motion stage.

摘要： Methods and systems for predicting out-of-stock occurrences and for assigning root causes to out-of-stock occurrences are described. In one implementation, inventory data and point of sale data are collected. An expected lost sales value is determined. A true demand is determined based on the point-of-sale data and the expected lost sales value. A probability of an out-of-stock occurrence is determined based on the inventory data. In another implementation, an out-of-stock occurrence is identified. The out-of-stock occurrence is classified, and one or more root causes are assigned to the out-of-stock occurrence.

摘要： A monitoring system provides for monitoring the optical performance of a plurality of different channels of a fiber optic network, each channel having an associated channel wavelength. The system includes: means for generating a calibration signal including a plurality of stable calibration wavelengths; means for combining a tapped communication signal and the calibration signal to generate a combined signal; and a multi-channel monitoring device. The monitoring device includes: an input optical fiber for receiving the combined signal, and for radiating an input light beam including the communication wavelengths and the calibration wavelengths; a detector unit having an array of pixel detector elements each being responsive to light beams incident thereon, and operative to generate an associated data signal; collimating and focusing means for collimating and focusing beams propagating between the fiber end and the detector unit; and a transmissive grating assembly for diffracting and spatially separating beams propagating between the input fiber end and the detector unit. The grating assembly, collimating and focusing means, and pixel detector elements are configured so that the diffracted beams are spatially separated and focused onto associated ones of the detector elements according to their wavelengths. A data processing unit receives the data signals from the detector unit, and is operative to provide information indicative of the intensities and wavelengths associated with each of the channels of the main communication signal. The processing unit uses the calibration wavelengths as standards to calibrate positional relationships between the spatially diffracted beams and the associated pixel detector elements.
