  • Publication number: 20160289050
    Abstract: An apparatus for a crane comprises a large-cavity pressure sensor, a small-cavity pressure sensor, a controller, a telescopic oil cylinder, and a telescopic oil cylinder regulator. The large-cavity pressure sensor can measure the oil pressure in a large cavity of the telescopic oil cylinder. The small cavity pressure sensor can measure the oil pressure in a small cavity of the telescopic oil cylinder. The controller can control an output electrical signal according to a large-cavity oil pressure fed back by the large-cavity pressure sensor and a small-cavity oil pressure fed back by the small-cavity pressure sensor, and, by means of the electrical signal, control a change of the amount of hydraulic oil flowing into and out of the large cavity and the small cavity of the telescopic oil cylinder so as to regulate the oil pressures in the large cavity and the small cavity.

  • Patent number: 9357105
    Abstract: To determine if a pixel exhibits artifacts, statistics are generated for the pixel and its neighbors. These statistics are compared with thresholds. If the comparison of the statistics and the thresholds suggests that the pixel exhibits a pixel artifact, then recourse can be taken, either to adjust the pixel value in some way, or to reject the angle of interpolation used in computing the value for the target pixel.

  • Patent number: 8004544
    Abstract: A boost table stores adjusted target levels for pairs of original and target pixel levels. The adjusted target levels can be used to as a substitute for the target pixel level to improve pixel response in reaching the desired target pixel level. A reduced boost table can be used, storing a subset of the adjusted target levels. Fuzzy logic control rules can be used to calculate adjusted target levels not actually stored in the reduced boost table.

  • Publication number: 20110136658
    Abstract: A catalyst used in the reaction of oxidative bromination of methane is provided. The catalyst is prepared by the following procedures: mixing at least one of the precursors selected from the compounds of Rh, Ru, Cu, Zn, Ag, Ce, V, W, Cd, Mo, Mn, Cr and La which can dissolve in water with the Si precursor, hydrolyzing, drying and sintering. In the catalysis system, methane reacts with HBr, H2O and oxygen source (O2, air or oxygen-rich air), finally CH3Br and CH2Br2 are produced. Another catalyst used in the reaction of condensation of methane bromide to C3-C13 hydrocarbons is also provided. This catalyst is prepared by supporting compounds of Zn or Mg on molecular sieves such as HZSM-5, HY, Hb, 3A, 4A, 5A or 13X et al. With this catalyst, CH3Br and CH2Br2 produced in the former process can react further to give C3 to C13 hydrocarbons and HBr, and HBr can be recycled as a medium.

  • Patent number: 7941007
    Abstract: To interpolate a value for a pixel, multiple patterns are selected. Each pattern is used to determine a pixel angle. One of the determined pixel angles is then selected based on the reliability of the pixel angles. The selected pixel angle can be selected based on its reliability irrespective of the reliability of other pixel angles. The selected pixel angle can then be used to interpolate a value for the target pixel. Dynamic thresholds can be computed for use in either determining a pixel angle for a given pattern, or to select the pixel angle from the available determined pixel angles.

In certain embodiments, the hydrolytically degradable crosslinked hydrogel substantially hydrolyzes only at about physiological pH. In certain embodiments of the method, the hydrolytically degradable crosslinked hydrogel is stable at low pH. In certain embodiments of the method, the hydrolytically degradable crosslinked hydrogel comprises a marker molecule, such as a dye, radiopaque, or an MRI-visible compound. It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.

  • Patent number: 7742103
    Abstract: A method and system for performing fuzzy logic based de-interlacing on film source fields that might be mixed with video on film. An embodiment of the invention comprises an adaptive de-interlacer by weighing between merge operation and interpolation operation in the case of occurring video on film motion object. A weighing factor is generated from video on film pattern based on fuzzy logic inference rules. This weighing factor specifies the weighting between merging and interpolating in assigning the pixel values of the progressive display output.
