A vehicle-mounted object detection system utilizing vertical cavity surface emitting laser diodes as an emitter source to alert a motor vehicle operator to the presence of another moving vehicle in a monitored zone. The bracket assembly includes a first, relatively more rigid member including a first mounting flange and a second, relatively more flexible member including a second mounting flange. A control electrode of the trench gate type is formed in a trench, which is formed in depth through the semiconductor base layer to the first semiconductor pillar. AM screening and applying pure color. Each of these pin-shaped members supports the moving frame in parallel to the fixed plate, has ends that contact the fixed plate and the moving frame and that have curved surfaces, and tilts in the substantially perpendicular direction in response to movement of the moving frame about the one end as a fulcrum.
