Abstract
The present invention discloses methods and systems for continuously repositioning a shading element to shade an eyepoint from the direct rays originated from a source of radiation. Different ways to simplify the methods are presented, including the use of a repositioning means which continuously repositions the shading element to shade a target location from the direct rays. Also suggested are novel devices to serve as the repositioning means, which may be incorporated in the systems. In embodiments as a visor system on transportation vehicles, this invention avoids a number of shortcomings and limitations of prior systems. It provides practical solutions to the dual problem with conventional visors: their size were too big and too small. This invention enables the vehicle occupants to have a more open field of view while the eyes are always protected from direct sunglare, making it safer and more pleasant to travel.
