Abstract: A head-up display includes: an image generator that emits display light that forms a display image; a second reflective mirror that forms a virtual image on a side opposite to an observer relative to the windshield; and a housing that houses the image generator and the second reflective mirror. The second reflective mirror includes: a base that is elongated and includes a first surface and a second surface, the first surface including a reflective surface that guides the display light to the windshield, the second surface being a rear surface of the first surface; and a raised wall that extends upward from a terminal edge of the second surface and extends in a longitudinal direction of the base. The center portion of the raised wall in the longitudinal direction is lower than each of both end portions of the raised wall in the longitudinal direction.

Abstract: The present disclosure promotes distribution of sensor data among a plurality of business operators. A controller that an information processing system according to the present disclosure includes collects first data including a plurality of items and personal information from mobile bodies belonging to a first business operator. The controller converts the first data to second data not being usable to identify individuals. The controller provides data in a range decided based on content of a predetermined data use contract, among the second data, to a second business operator. The controller calculates a consideration for the data that is to be paid by the second business operator, based on a data use record of the second business operator.

Abstract: A display device includes a light source, an optical system, a liquid crystal panel, and a first heat sink. The optical system converts light emitted from the light source into irradiation light that is to be an irradiation area having a predetermined width. The liquid crystal panel receives the irradiation light. The first heat sink includes an opening through which the irradiation light passes, and supports the liquid crystal panel. The first heat sink is in contact with the liquid crystal panel.
