Abstract: An illumination apparatus has a circular base plate and a plurality of tracks arranged radially about the base plate. LED modules are disposed upon the tracks, and transmission members coupled to the LED modules move the LED modules along the tracks. A distance measurement sensor is mounted on one side of the base plate, and is used to measure a distance value of an illuminated object. A processor is configured to determine a desired radius value for the plurality of LED modules based on the distance value and move the transmission members according to the desired radius value.

Abstract: A carriage system for a printing apparatus is disclosed. The carriage system includes a movable carriage for carrying at least one ink pen, a carriage rod on which the carriage is rotatably mounted, an anti-rotation rail that is adjacent to one end of the carriage to prevent the rotation of the carriage in one direction, and a spring-loaded preloader coupled to an underside of the carriage to prevent the rotation of the carriage in the opposite direction and to urge the carriage against the anti-rotation rail. The preloader includes a preloader body made of a nonmetallic material, a roller operable to roll along a surface below the carriage, and a resilient spring.
