Abstract: An information generation device generating a test case being a simulation model for reproducing a road traffic condition in an area on a road including a target point, the information generation device including: a first storage unit that stores moving-object information being information regarding a moving object existing in the area; a determination unit that determines whether or not an incident in which the moving object existing in the area shows a behavior that leads to occurrence of an accident has occurred, on the basis of the moving-object information; an extraction unit that extracts, as target information, moving-object information in a target period being a predetermined time period including a time point at which the incident occurred; and a generation unit that generates the test case upon occurrence of the incident on the basis of the target information.

Abstract: A detection device, which detects a behavior of a vehicle in a preset detection area using a laser radar that generates point cloud information by irradiating the detection area with laser light and receiving reflected light resulting from the irradiation with the laser light, includes an acquisition unit configured to acquire the point cloud information, a vehicle detection unit configured to detect a vehicle on the basis of the point cloud information, and a behavior detection unit configured to detect a target behavior that is a vehicle behavior subjected to detection in response to the vehicle detected by the vehicle detection unit having moved from a first area to a second area, in which the first area and the second area are included in the detection area and are set according to the target behavior.

Abstract: A cavity has a longitudinal hollow having opposite open ends. An excitation source, such as a YAG rod, is accommodated in the hollow of the cavity. A hollow, cylindrical rod holder is inserted into each of the opposite open ends of the hollow and is fitted over a corresponding end of the YAG rod. A seal is fitted into a hollow of the rod holder adjacent to a portion of the rod holder fitted over the end of the YAG rod. The seal includes an annular seal body with a U-shaped section, e.g. made from Teflon®, and fitted over an outer periphery of the YAG rod to grip the YAG rod, as well as a spring fitted in a groove of the seal body provided by the U-shaped section so as to circumferentially surround a gripped portion of the YAG rod.
