Abstract: A system, apparatus and method for spatially distributed, spectrally neutral optical attenuation. One embodiment of the apparatus can include: an attenuator fin plate; a set of attenuator fins, wherein each of the fins is operably coupled to the fin plate at a preset fin angle to the fin plate normal such that the attenuator fins maintain their position relative to the fin plate as the fin plate moves; and a motor for rotating the fin plate a set angular distance around an axis of rotation, wherein the axis of rotation is at a preset fin plate angle to a light beam direction of travel and wherein the attenuator fins block varying amounts of the light beam as the fin plate is rotated through the set angular distance. The attenuator fin plate and attenuator fins can be a single, integral component, wherein the attenuator fin plate is etched and stamped to form the attenuator fins, or separately formed components that are attached, for example, to a separate frame.

Abstract: A child safety seat assembly, including a base for being positioned on a vehicle seat bottom. An anti-rebound bar is carried by the base and extends outwardly and upwardly from a foot end of the base for engaging a seat back of the vehicle seat to which the seat is attached for retarding inertia-induced rotation of the base and the attached carrier by transmitting rotational force applied to the seat during a sudden change in velocity into the seat back of the vehicle seat onto which the seat is attached.
