IPC: G08G1/16
Filed: 2022-01-20
Abstract: To provide a driving assist device that can correctly guide a driver in the direction of a designated traffic division even when the driver has advanced to a traffic division designated as a direction other than the desired travel direction.SOLUTION: When detecting an intersection ahead of an own vehicle M, a driving assist control unit 22 designates a predictive advancing course as of a time of entering the intersection on the basis of a vehicle behavior inferred prior to entering the intersection from a temporal change in own vehicle position information.

Title: Light-emitting element, light-emitting device, electronic apparatus, and illumination device
IPC: H01L51/50
Filed: 2022-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a light-emitting element with high external quantum efficiency and a light-emitting element with long life. 
     SOLUTION: A light-emitting element includes a light-emitting layer containing a guest material and a host material between a pair of electrodes. An emission spectrum of the host material and an absorption spectrum of the guest material overlap. Excitation energy of the host material is converted into excitation energy of the guest material and phosphorescence is emitted. Since an energy shift from the host material to the guest material occurs smoothly using the overlap between the emission spectrum of the host material and the absorption spectrum of the guest material, the light-emitting element has high energy shift efficiency. Therefore, the light-emitting element has high external quantum efficiency.
