Abstract: A power management system includes a plurality of power stations, a plurality of vehicles capable of exchanging power with any of the power stations, and a server configured to communicate with the plurality of vehicles and the plurality of power stations. When each power station receives power from the vehicle or supplies power to the vehicle, each power station associates a power amount received from the vehicle or a power amount supplied to the vehicle with a user ID of the vehicle, and transmits the power amount to the server. The server sets a value point based on the power amount received from the power station, and provides the value point to the user having the user ID associated with the power amount.

Abstract: A head-up display device that superimposes a plurality of virtual images different in display distance (depth perception) on each other and display the superimposed virtual images is provided with a simple configuration. A head-up display device includes a synthetic optical system and a projection optical system. The synthetic optical system superimposes and emits first image light that travels through a first optical path and second image light that travels through a second optical path having an optical path length different from an optical path length of the first optical path.
