  • Patent number: 10592785
    Abstract: Methods, apparatus, and systems are provided for integrated driver expression recognition and vehicle interior environment classification to detect driver condition for safety. A method includes obtaining an image of a driver of a vehicle and an image of an interior environment of the vehicle. Using a machine learning method, the images are processed to classify a condition of the driver and of the interior environment of the vehicle. The machine learning method includes general convolutional neural network (CNN) and CNN with adaptive filters. The adaptive filters are determined based on influence of filters. The classification results are combined and compared with predetermined thresholds to determine if a decision can be made based on existing information. Additional information is requested by self-motivated learning if a decision cannot be made, and safety is determined based on the combined classification results. A warning is provided to the driver based on the safety determination.

  • Publication number: 20060140821
    Abstract: A laboratory sample plate for use in PXRD and other testing techniques includes a quartz body having substantially planar top and bottom surfaces that are parallel with each other. The quartz body includes a matrix of cylindrical apertures that are substantially perpendicular to the top and bottom surfaces. Each aperture has an upper opening at the top surface and a lower opening at the bottom surface of the plate body. A synthetic quartz bottom sheet is fused to the bottom surface of the quartz body. The quartz bottom sheet include respective portions that close the lower opening of each aperture in the quartz body, such that each aperture and respective portion of the bottom sheet together form a well for receiving a sample. Each aperture and respective portion of the bottom sheet are suitably dimensioned to perform a powder X-ray diffraction technique as well as microscopy and Raman spectroscopy on a sample contained in the well.
