  • Patent number: 7818080
    Abstract: It is one object of the present invention to provide a program writing method of numerical controller, a numerical controller and a cutting machine controlled thereby, achieving the writing of a plurality of programs relating to one axis to perform a high efficiency in a lot of productions. A next or later user-set-program controlling a duplicated axis controlled by plural user set programs identifies a virtual axis virtually controlled by one user set program. A program is written to replace the duplicated axis with the virtual axis. A control amount calculated by the user set program identifying the virtual axis is added to a control amount inputted to a correspondent axis driving program as a control amount of the duplicated axis before replacing the virtual axis.

  • Patent number: 7731323
    Abstract: With this invention, compatibility between an image forming apparatus and a component mounted on the image forming apparatus is precisely checked. A cartridge, as the component, stores its ID (first information) and an ID (second information) of the image forming apparatus that can use the cartridge. The image forming apparatus stores its ID (third information) and an ID (fourth information) of the cartridge that can be used in the image forming apparatus. Then, when the fourth information includes the first information or the second information includes the third information, it is decided that the cartridge mounted in the image forming apparatus can be used. When the fourth information does not include the first information and the second information does not include the third information, it is decided that the cartridge mounted in the image forming apparatus cannot be used.

  • Patent number: 7719575
    Abstract: A regression analysis is carried out (8) using pixel signals having a K-th spectral characteristic as the explanatory variable and pixel signals having an L-th spectral characteristic as the purpose variable in a plurality of pixel positions in an area neighboring a pixel of interest to obtain a pixel signal having the L-th spectral characteristic (9). Pixel signals obtained by low-pass filtering (7a-7c) of the output signals of an imaging device may be used as the explanatory variable and the purpose variable. The occurrence of false colors is thereby reduced when, in a group of pixel signals from pixels arrayed on a two-dimensional plane, each pixel having one of a plurality of spectral characteristics, the missing colors at each pixel position are obtained by interpolation.

  • Publication number: 20100088024
    Abstract: A support control unit for determining a traveling condition of a host vehicle during an exit from a main road to an access road determines whether or not the condition of the host vehicle at a given point in time corresponds to an exit start scene or an exit completion scene for detecting the start of an exit or completion of the exit on the basis of a host vehicle position, route data, map rendering data, or lane information including at least road surface marking positions, and determines that an exit start timing or an exit completion timing of the host vehicle has arrived when the condition is determined to correspond to the exit start scene or the exit completion scene. Hence, during the exit from the main road to the access road, the traveling condition of the host vehicle can be determined accurately. The support control unit also determines the traveling condition of the host vehicle during convergence with the main road from the access road.
