  • Patent number: 11997507
    Abstract: A line-of-sight determination method includes: a point cloud data acquisition step of acquiring point cloud data including a first position indicating a position of a first wireless station and a plurality of second positions indicating positions on a structure serving as a candidate in which a second wireless station opposing the first wireless station is to be installed; and a line-of-sight determination step of determining whether or not there is a line of sight between the first position and at least one of the second positions, and determining whether or not there is a line of sight between the first wireless station and the structure based on the determination result.

  • Patent number: 11956643
    Abstract: A station placement design method includes: extracting candidates for an installation location of a wireless base station from point group data in accordance with designated conditions for an installation location of a wireless base station; determining presence/absence of visibility between a plurality of designated wireless terminal stations and the candidates for an installation location of a wireless base station based on the point group data and generating a first list including information in which the candidates for an installation location of a wireless base station and wireless terminal stations determined to have presence of visibility for the candidates for an installation location of a wireless base station are associated with each other; generating a second list including information representing combinations of the candidates for an installation location of a wireless base station that enable all of the plurality of designated wireless terminal stations to be accommodated based on the first list

  • Patent number: 11916610
    Abstract: An interference evaluation method for evaluating, over an area, radio-wave interference that occurs between a first radio station and a second radio station includes: a distinguishing step of acquiring information indicating topographic cross-sections of respective azimuths centered about the first radio station, and distinguishing the topographic cross-section into a segment in which there is visibility from the position of the first radio station and a segment in which there is no visibility from the position of the first radio station; and a specification step of specifying a position at which a desired interference amount is reached based on a distance between the first radio station and the second radio station in a segment distinguished as having visibility from the position of the first radio station, and specifying a position at which the desired interference amount is reached by evaluating the radio-wave interference for each square of an evaluation target region segmented into squares in a segment d

  • Patent number: 8524033
    Abstract: To provide: a coated wood composite having surface properties such as transparency, smoothness, gloss, uniformity, and depth, and excellent in various physical properties such as durability and strength; and a method for producing such a coated wood composite efficiently and easily. A coated wood composite produced by placing an unsaturated polyester resin composition on a decorative veneer and heat-pressing the decorative veneer and the composition placed thereon to mold the composite, wherein the unsaturated polyester resin composition comprises: an unsaturated polyester; a polymerizable monomer; and an isocyanate component essentially including an aliphatic diisocyanate.

  • Publication number: 20110170776
    Abstract: An image processing apparatus is provided which makes it possible to improve an access speed for accessing a storage device so as to improve an image processing velocity without increasing a capacity of the storage device. The apparatus includes an optical system; an imaging device having a plurality of pixels each corresponding to one of colors and an arithmetic calculating section to process image data. When a color of an original pixel is different from that of a distortion-corrected pixel, the arithmetic calculating section conducts an interpolation processing to calculate pixel data of the distortion-corrected pixel from other pixel data of plural pixels residing at peripheral positions surrounding the original pixel, stored in advance, and the arithmetic calculating section stores pixel data categorized in one of the colors as a continuous series of the pixel data into corresponding one of storing areas provided in the storage section.
