Abstract: There is provided a photoelectric switch capable of accurately detecting even such a workpiece where a tint changes within the same workpiece, while preventing erroneous detection. The photoelectric switch includes: a light projecting unit; a light receiving unit; a coincidence degree calculating unit for comparing the acquired color information with a reference color to calculate a coincidence degree of both of the color information. When the color information is newly acquired, a detection signal generating unit compares, with a detection determination threshold, the highest coincidence degree of coincidence degrees calculated by respectively comparing the color information newly acquired, with the two or more reference colors, to perform workpiece determination.

Abstract: A method of processing hyperspectral data includes receiving the hyperspectral data. The hyperspectral data includes spectral data for each pixel in a two-dimensional array of pixels, and for each spectral band in a set of multiple spectral bands associated with each pixel. The hyperspectral data is converted into one-dimensional spectra. Each one-dimensional spectrum includes, for a single pixel of the pixels, the spectral data for each spectral band in the set of multiple spectral bands associated with the single pixel. Each one-dimensional spectrum is inputted to a trained transformer neural network. For each one-dimensional spectrum, the trained transformer neural network is used to spectrally un-mix the spectral data in the set of multiple spectral bands.

Abstract: In some implementations, a device may identify, based on spectroscopic data, a pseudo steady state end point indicating an end of a pseudo steady state associated with the blending process. The device may identify a reference block and a test block from the spectroscopic data based on the pseudo steady state end point. The device may generate a raw detection signal associated with the reference block and a raw detection signal associated with the test block. The device may generate a statistical detection signal based on the raw detection signal associated with the reference block and the raw detection signal associated with the test block. The device may determine whether the blending process has reached a steady state based on the statistical detection signal.
