Each color reference point represents the color value of an existing siding product. The system determines a “distance” between the desired color point and each plotted color reference point within the color space and identifies the siding product associated with the color reference point that is located the shortest distance to the desired color point within the color space.

  • Patent number: 9973614
    Abstract: An electronic device is operated based on whether it detects vibration indicative of natural human tremors while the device is not enclosed in a small space. Human tremors are detected by sampling a motion signal and performing a discrete Fourier transformation on a plurality of sets of samples. For each sample, a mean magnitude is calculated for a first range of frequencies indicative of human tremors. A mean magnitude is also calculated for a second range of frequencies greater than the first range. If the difference between the mean magnitude of the first range and the mean magnitude of the second range, then human tremors are detected for the set of samples. Human tremors are detected for the device if a threshold number of sets of samples within a predetermined time period produce an output indicating detection.

  • Patent number: 8355581
    Abstract: A system detects an object contour with an image acquisition assembly, the object moving relative to the assembly. A line detector scans the surface line by line during a scan cycle, the line being transverse to the relative motion direction. During active periods, a light source emits light synchronized with the scan cycle, allowing the line detector to acquire a first group of at least one lit scan line. A second group of unlit scan line(s) is acquired during non-emitting idle periods. The object passes between the line detector and the light source. A processor receives and analyzes acquired scan lines. For each lit scan line group and a successive second unlit scan line group, the processor identifies a token pattern with a lit segment adjoining an unlit segment. The processor searches the first and second groups for the token pattern ending or reappearing to produce an object contour.

  • Patent number: 8305587
    Abstract: A metrology tool (1) for measuring the positions of structures (32) on a mask surface (31) is disclosed. On a measuring stage (33) a reflector (36) selective with respect to the wavelength is provided, which essentially reflects light within a first wavelength region emitted from a first illumination device (10), and essentially does not reflect light within a second wavelength region emitted from a second illumination device (20). The reflector (36) selective with respect to the wavelength preferentially is a dichroic mirror. By detecting the light within the first wavelength region reflected by the reflector (36) the position of predefined sections of outer edges (37) of the mask is determined. The light from the second wavelength region is used for determining the coordinates of structures on the mask.

  • Patent number: 8300919
    Abstract: Edge points are extracted by specifying a height (values indicating a distance from a substrate) on a pattern when edges of the pattern are extracted from a CD-SEM image. Further, LER values obtained by the extraction of a Fourier spectrum of the LER are obtained. When the same sample is previously observed with the AFM and the CD-SEM, a size of the LER obtained by specifying a height, an auto-correlation distance of the LER, or an index called the spectrum is obtained from results of the AFM observation. Further, theses indices obtained by specifying image processing conditions for detecting the edge points from the CD-SEM observation result are obtained. Also, it is determined that heights providing values when the values are matched correspond to the image processing conditions and then, the edge points are extracted from the CD-SEM IMAGE instead of the AFM observation by using the image processing conditions.

  • Patent number: 8019149
    Abstract: A pattern shape evaluation method for deciding whether a pair of patterns are disconnected or connected. The method includes extracting a plurality of pattern contour points that make up a contour of a pattern in a measurement region, and creating two pattern contour point sequences based on the plurality of pattern contour points. Each of the two pattern contour point sequences includes a set of the pattern contour points. In the pattern contour point sequence, each of distances between neighboring pattern contour points is equal to or smaller than a predetermined value. The method includes calculating an angle between a line passing through two of the pattern contour points which provide a shortest distance between the two pattern contour point sequences and a reference line arbitrarily defined with respect to the measurement region. The method further includes deciding whether the patterns are disconnected or connected, based on the angle.
