Abstract: An optical device includes a first waveguide extending in a first direction and a second waveguide connected to the first waveguide. The second waveguide includes a first mirror, a second mirror, and an optical waveguide layer. At least either the first waveguide or the second waveguide has one or more gratings in a part of a connection region in which the first mirror, the second mirror, and the first waveguide overlap one another when seen from an angle parallel with a direction perpendicular to a first reflecting surface of the first mirror. The one or more gratings is at a distance that is longer than at least either a thickness of the first mirror or a thickness of the second mirror in the first direction from an end of the first mirror or the second mirror that is in the connection region.

Abstract: The present invention relates to a method and system for restoring a transferred mobile service by a mobile transfer service. To this end, the present invention provides a method for restoring a mobile service that releases a mobile transfer state of a first mobile terminal when it is confirmed that a state where the power strength of a common pilot channel received from a second mobile terminal is a previously set threshold value or less is maintained for a previously set threshold time or more. In addition, the present invention provides a method for restoring mobile service that releases a mobile transfer state of the first mobile terminal when it is confirmed that the frequency of a period that is the power threshold value or less of the common pilot channel received from the second mobile terminal exceeds the previously set threshold frequency within the previously set time unit.

Abstract: An onboard vehicle information notifying apparatus has a moving body position acquiring section that acquires a moving body position for at least one moving body existing in a vicinity of a host vehicle and that acquires map information of the vicinity of the host vehicle. The map information is divided into a plurality of unit regions, with each of the unit regions being a notification necessary region when the moving body exists in the unit region. An information acquiring section acquires an advancement speed and an advancement direction of the host vehicle, and a prescribed movement speed of the moving body. An information providing zone setting section sets an information providing zone within which existence of the moving body should be reported. The information notifying section reports the existence of the moving body when the information providing zone overlaps with the notification necessary region.
