  • Publication number: 20090253378
    Abstract: The present invention provides with a terminal having a monitoring period changing function for changing the value (monitoring period) of a no-traffic monitoring timer of the terminal by feeding back the information on radio signal conditions, and a no-traffic monitoring function for changing the status of the call of the terminal to “a disconnected state for only receiving radio signal from a base station” depending on the value (monitoring period) of the no-traffic monitoring timer based on the information fed back.

  • Publication number: 20080151324
    Abstract: The present invention provides a surface-reading apparatus that includes a subject-flexing mechanism and a surface-reading component. The subject-flexing mechanism causes a subject to flex in one of a convex form and a concave form. The surface-reading component reads a characteristic of a surface condition of the subject that has been flexed by the subject-flexing mechanism. The surface-reading component can includes an optical reading component that optically reads the characteristic of the surface condition of the subject. The optical reading component may be a reflected light-reading component that reads the characteristic of the surface condition of the subject with reflected light or may be a transmitted light-reading component that reads the characteristic of the surface condition of the subject with transmitted light.

  • Publication number: 20080060079
    Abstract: To determine authenticity of a solid body simply and precisely, a reference area of a paper sheet which is genuine is optically read from two different directions, and the image is registered as a reference image. A check area of a paper sheet subjected to the authenticity determination, including the reference area and having a size larger than the reference area, is read from two different directions with a scanner, and data on a partial area having the same size as the reference area are extracted from each set of check data collected by the reading. For a set consisting of the reference image and the check image optically read from the same direction, the value of the correlation with the reference image is repetitively calculated by the normalized correlation method while the partial area is shifted within the check area. The maximum correlation value and the normalized score of the maximum correlation value are compared with respective thresholds to determine the authenticity of the paper sheet.
