Abstract: In one aspect, a reception means receives, from a roadside device, first information transmitted from a mobile body by using a first wireless communication. An identification means identifies, based on information of a terminal apparatus to be managed by an information management means, the terminal apparatus being located in the vicinity of the mobile body that has transmitted the first information. A transmission means transmits second information generated based on the first information, to the terminal apparatus identified by the identification means via a second wireless communication.

Abstract: A liquid ejecting device includes: a printing unit including a liquid ejecting head configured to eject a liquid to a medium and a head holder configured to form an air cooling path, and a cooling mechanism configured to cause air in the air cooling path to flow therethrough to air-cool the liquid ejecting head, wherein the printing unit is provided so as to be movable with respect to a transport path along which the medium is transported, the cooling mechanism includes a first air hole and a second air hole that are configured to be coupled to the air cooling path, and the air cooling path is coupled to one of the first air hole and the second air hole corresponding to a position of the printing unit.

Abstract: A driving assistance device that performs steering operation of a vehicle. The device includes a travel track creation device having a curvature waveform creator that creates a waveform representing a curvature of a reference travel track. A first changer changes first and second edge portions of the waveform to a ramp shape and provides the waveform with first and second ramp-shaped portions. A second changer changes each of the first and second ramp-shaped portions to a curve and provides the waveform with first, second, third, and fourth curve portions. A travel track creator creates the travel track based on the waveform. A controller provides a steering signal according to the travel track.

Abstract: A travel track creation device includes: a curvature waveform creator that creates a waveform representing a curvature of a reference travel track that is a track on which a vehicle travels along a road and includes an inlet straight track, an arc track continuous to the inlet straight track, and an outlet straight track continuous to the arc track; a first changer that changes each of first and second edge portions that are two edges of the waveform to a ramp shape and provides the waveform with first and second ramp-shaped portions; a second changer that changes each end of each of the first and second ramp-shaped portions to a curve and provides the waveform with first, second, third, and fourth curve portions; and a travel track creator that creates the travel track based on the waveform.
