摘要： An apparatus for characterizing multilayer samples is disclosed. An intensity modulated pump beam is focused onto the sample surface to periodically excite the sample. A probe beam is focused onto the sample surface within the periodically excited area. The power of the reflected probe beam is measured by a photodetector. The output of the photodetector is filtered and processed to derive the modulated optical reflectivity of the sample. Measurements are taken at a plurality of pump beam modulation frequencies. In addition, measurements are taken as the lateral separation between the pump and probe beam spots on the sample surface is varied. The measurements at multiple modulation frequencies and at different lateral beam spot spacings are used to help characterize complex multilayer samples. In the preferred embodiment, a spectrometer is also included to provide additional data for characterizing the sample.

摘要： A method and apparatus to be used with a motor controller for determining RMS line current during a start-up period or a stalled period using electrical values known to the controller. Various equations relate RMS line current to monitored thyristor and source voltages as well as the duration of non-conducting periods in line voltages to determine the RMS line current.

摘要： A direct-view stereoscopic confocal microscope including a light source, an aperture plate, image collector, and first and second vibrators. The light source is used for illuminating a portion of a specimen and the aperture plate is used for passing a portion of the light emanating from the light source onto a portion of the specimen. The image collector is optically coupled to the illuminated portion of the specimen and acts to separate the image created by the illuminated portion of the specimen from the light illuminating the specimen. A first vibrator is coupled to the specimen for vibrating the specimen along a first axis and the second vibrator is coupled to the image collector, and synchronized with said first vibrator, for vibrating the collecting means along a second axis.

摘要： The invention discloses a method of improving the brightness of liquid crystal projectors, comprising the following steps: step 1: one pixel is composed of three sub-pixels; increasing the area ratio of green sub-pixels in the pixel and reducing the area ratio of red and blue sub-pixels; step 2: the illumination light source does not follow the RGB ratio of white light; under the condition that the total luminous energy remains unchanged, reducing the ratio of green light in the light source, and increasing the ratio of red light and blue light in the light source; step 3: multiplying the RGB ratio by the corresponding sub-pixel area, and the obtained result conforms to the RGB ratio in white balance. By changing the luminosity of pixels and RGB, more light can be transmitted under the same light energy density, which is an important method to improve the brightness of liquid crystal projectors.

摘要： Methods, apparatus, systems and articles of manufacture for detecting a side channel attack are disclosed. An example apparatus includes a histogram generator to generate a histogram representing cache access activities. A histogram analyzer is to determine at least one statistic based on the histogram. A machine learning model processor is to apply a machine learning model to the at least one statistic to attempt to identify a side channel attack. A multiple hypothesis tester to perform multiple hypothesis testing to determine a probability of the cache access activities being benign. An anomaly detection orchestrator is to, in response to the machine learning model processor identifying that the at least one statistic is indicative of the side channel attack and the probability not satisfying a similarity threshold, cause the performance of a responsive action to mitigate the side channel attack.
