Abstract: A semiconductor light emitting element includes an optical waveguide having a first and second waveguide provided with a width that allows propagation of light in a second-order mode or higher and a multimode optical interference waveguide provided with a wider width than the first and second waveguide and arranged at a position therebetween. The semiconductor light emitting element further includes a first optical loss layer facing the first waveguide in an active-layer crossing direction for causing a loss of light that is propagating in the first waveguide in the second-order mode or higher and a second optical loss layer facing the second waveguide in an active-layer crossing direction for causing a loss of light that is propagating in the second waveguide in the second-order mode or higher, the active-layer crossing direction being orthogonal to a surface of an active layer.

Abstract: A parking assist apparatus is configured to perform a deviation control including at least one of a first notification control and a stop control when the parking assist apparatus determines that a vehicle that is performing an automatic parking deviates from a learned route. The parking assist apparatus is configured to learn, as the learned route, a position of the vehicle in each of multiple learned images that an outside-vehicle camera captures a space including the vehicle and the parking space multiple times while the vehicle is performing a manual parking or the automatic parking; and perform the deviation control when the parking assist apparatus determines that the vehicle deviates based on a position of the vehicle in a comparative image and a position of the vehicle in the learned image.

Abstract: A parking assistance system includes: a non-on-board sensor that is able to acquire first information that is three-dimensional information of a first area including a target parking space being a target area in which an own vehicle is parked; an on-board sensor that is able to acquire second information that is three-dimensional information of a second area being a surrounding area of the own vehicle and constituting a part of the first area; and a control device configured to determine a route along which the own vehicle moves to the target parking space based on the first information and the second information and to control the own vehicle such that the own vehicle moves along the route.

Abstract: A recording control device includes: a photographic data acquisition unit that acquires photographic data from a camera that photographs a periphery of a vehicle; a moving object detection unit that detects a moving object from the photographic data acquired by the photographic data acquisition unit while the vehicle is parked; and a recording control unit that correlates detection information of the moving object with the photographic data, records the correlated information in a recording unit as a data file that is capable of being overwritten, and when overwriting of the data file in the recording unit becomes necessary, performs the overwriting by reducing the priority of overwriting on the data file in which the moving object is detected.
